Steady Flow Of A Micropolar Fluid Through Coaxial Circular Cylinders Under Constant Pressure Cradient

Authors:

DOI NO:

Abstract:

The aim of this paper is to investigate the problem of steady flow of micropolar fluid  in an annulus bounded by two co-axial circular cylinders of radii a and b, b being greater than a. The annular flow takes place under the action of constant pressure gradient. The velocity and microrotatioin component as well as the rate of discharge of the fluid through the annulus and time of efflux have been derived analytically in closed froms. Numerical calculations have been  given to find out the velocity in viscous fluid and a percentage decrease in micropolar fluid and a persentage decrease in micropolar fluid over viscous fluid corresponding to this flow have been compared. The microrotation has also been calculated. It is clear from the numberical calculations that the fluid velocity is always less in micropolar fluid than in viscous fluid. Also the rate of discharge in micropolar fluid is considerably less than that of viscous fluid. In fact, all important results are less in micropolar fluid than the viscous fluid.

Authors:

DOI NO:

Abstract:

The aim of this paper is to study the radial vibration of a non-homogeneous sherically anisotroplc elastic spherical shell with an isotropic elastic inclusion as the core. The non-homogeneous of the material is characteised by taking linear vibration with radial distance of elastic parameters and mass density. This property of non-homogeneity is assumed to be satisfied by the entire shell of the sphere, while the core of the spherical shell behaves like an inclusion of isotropic homogeneouselastic mass. Satisfying the appropriate boundary conditions, the frequency of vibration of the composite solid sphere has been determined. results obtained by other authors may be deduced from our more general result as special cases.

Propagation Of Waves In A Microstretch Elastic Solid Layer

Authors:

DOI NO:

Abstract:

• Starting from the fundamental equations of motion for liner homogeneous isotropic microstretch elastic solid media, two dimensional wave propagation in a microstretch layer has been investigated in this paper. Under suitable boundary conditions concerned frequency equations involving a eighth order determinant has been obtained. Expressing the determinant as a product of two fourth order determinants, several possibilities and the corresponding wave velocities have been found out in closed forms. Two interesting particular cases when the large of the wave is very small or large relative to the thickness of the layer have been discussed. Graphs have been drawn to highlight the effect of microstretch and micropolarty in the propagation of waves. It is found that the wave velocity increases with the increase of the microelastic parameter while the stretch character of the medium causes diminution of the wave velocity.

Abstract:

The aim of the present paper is to investigate the propagation of waves in a magneto­visco-elastic initially stressed electrically conducting plate of finite thickness involving time rate of strain and stress of higher order. The initial stress is assumed to be of the nature of hydrostatic tension or compression.

Abstract:

n most recent time worrying epidemic was HIV, Influenza, Tuberculosis etc. While there are many complicating factors, simple mathematical models can provide much insight into the dynamics of disease epidemics and help officials make decisions about public health policy in this subject matter. We shall discuss two of the classical and still much used, deterministic epidemiological models which are responsible for spreading diseases in an area. We shall then consider a reaction-diffusion model, Fisher’s equation, a new integro-differential equation model for the spread of an epidemic in space and to evaluate strategies to control an epidemic.

BLOOD FLOW THROUGH A FLEXIBLE ARTERY IN PRESENCE OF STENOSIS – A MATHEMATICAL STUDY

Authors:

DOI NO:

Abstract:

The mathematical analysis presents the study of heat transfer and magneto hydrodynamic effects on pulsatile flow of blood through geometrically irregular arterial system, and its effects on cardiovascular disorder and arterial diseases. Considering the influence of magnetic field on the steno- tic artery, the effect of transverse magnetic field and multi-stenosis on the blood flow in blood vessels is studied theoretically. The blood flow is considered to be axi-symmetric with an outline of the irregular stenosis obtained from a three-dimensional casting of mild stenosed artery, so that the physical problem becomes more realistic from the physiological point of view. The MARKER AND CELL (MAC) and SUCCESSIVE –OVER-RELAXATION (SOR) methods are respectively used to solve the governing unsteady magneto-hydrodynamic equations and pressure-Poisson equation numerically. The present observations certainly have some clinical implications relating to magneto-therapy. It may help reducing the complex flow separations zones causing flow disorder and leading to the formation and propagation of the arterial diseases and cardiovascular disorders.

Abstract:

Aim of this paper is providing a novel method for evaluating emotion ilicitation procedures based on emotion recognition. Attention should be paid to physiological signals for emotion recognition compared to audiovisual emotion channels such as facial expression or speech. This paper focuses on an idea to define emotion from different perspectives and explore possible causes and variations of different parameters. Here the authors determined the scope of fuzzy relational approach to human emotion identification from facial expression. Initially the facial features are extracted from selective regions which are fuzzified and mapped onto an emotion space. This has been implemented using Mamdani type relational model. In subsequent stages Max-min inverse fuzzy relation has been used to determine the fuzziness of emotions if values of facial expressions are known.

In the subject matter of mathematical statistics, let the domain of mathematical activity that draws its inspiration from and nurtures the lead provided by the seminal paper of the American Economist and Nobel Prize (1970) winner P.A. Samuelson entitled, “How Deviant can you be?” and published in the Journal of the American Statistical Association in 1968, on the maximum and the minimum deviations, from the mean (denoted presently by m and ‘m respectively) in a set of n observations with given mean μ and standard deviation σ, be henceforth defined as the Samuelson Domain. The present communication is in the Samuelson Domain. A circle theorem in the −σmplane is rigorously established and exhibited step by step for the sheer delight of its simplicity and elegance. A crude first approximation yields a result that is inferior to Samuelson’s but a more precise investigation of the consequences of the circle theorem shows that Samuelson’s famous work on the existence of bounds, for a set of n real numbers, in terms of σμ, and n can be improved upon provided n exceeds a critical value.

We studied the equation of continuity and derived the Navier-Stockes (N-S) equations of motion for viscous compressible and incompressible fluid flow. Boundary layer and thermal boundary layer equations are also derived. Then we studied similar solution of boundary layer and thermal boundary layer equations. We also performed unsteady solutions of thermal boundary layer equations. We used some non-dimensional variable to non-dimensionalised thermal boundary layer equations. The non-dimensional boundary layer equations are non-linear partial differential equations. To find out the non-similar solutions of unsteady thermal boundary layer equation we used finite difference method. The effect on the velocity and temperature profiles for various parameters entering into the problems are separately discussed and shown graphically.

Pressure-Driven Flow Instability with Convective Heat Transfer through a Rotating Curved Channel with Rectangular Cross-section: The Case of Negative Rotation

Authors:

DOI NO:

Abstract:

Due to engineering applications and its intricacy, the flow in a rotating curved duct has become one of the most challenging research fields of fluid mechanics. A comprehensive numerical study is presented for the fully developed two-dimensional thermal flow of viscous incompressible fluid through a rotating curved rectangular duct of constant curvature1.0=δ. Numerical calculations are carried out by using a spectral method and covering a wide range of the Taylor number 02000<≤−Trand the Dean number 1000100≤≤Dn for the constant Grashof number100=Gr. A temperature difference is applied, that is the outer wall of the duct is heated while the inner wall is cooled. The rotation of the duct about the center of curvature is imposed, and the effects of rotation (Coriolis force) on the unsteady flow characteristics are investigated. Flow characteristics are investigated for the case of negative duct rotation. We investigate the unsteady flow characteristics for the Taylor number02000<≤−Tr and it is found that the unsteady flow undergoes in the scenario ‘steady-state→ periodic→ multi-periodic → steady-state’, if Tr is increased in the negative direction. Contours of secondary flow patterns and temperature profiles are also obtained at several values of Tr, and it is found that there exist two- and multi-vortex solutions if the duct rotation is involved in the negative direction.

State Space Analysis of a Solar Power Array Taking a Higher Degree Of Non-Linearity into Account

Authors:

DOI NO:

Abstract:

This paper develops a mathematical technique for the solution of a non linear state variable model of a solar array power system powering a non linear load. The significance of the technique lies in the fact that experimental complexities can be avoided to reach a desired conclusion regarding the design of the controller associated with a solar power array system. An iterative method has been used in which the initiating assumption has been made to consider the system to depend entirely upon its initial values at the instant t = 0 and taking the forcing function to be zero at that instant. In the next step we use the solution at t = 0 and plug it into the equation iteratively while having a non zero value of the forcing equation during the second iteration. The non linearity lies in the fact that the forcing function is a function of the state variable itself. We have applied the Maclaurin series to find the laplace transform of certain mathematical functions containing a singularity at the zero time instant. The time response is obtained and then it is plotted by using MATLAB and various graphs have been obtained.

Authors:

DOI NO:

Abstract:

In this paper, the similarity solution of natural convective laminar boundary layer flow around a vertical slender body with suction and blowing has been investigated. Firstly, the governing boundary layer partial differential equations have been made dimensionless and then simplified by using Boussinesq approximation. Secondly, similarity transformations are introduced on the basis of detailed analysis in order to transform the simplified coupled partial differential equations into a set a ordinary differential equations. The transformed complete similarity equations are solved numerically by using Fourth order Runge-Kutta method as well as MATLAB. Finally, the flow phenomenon has been characterized with the help of obtained flow controlling parameters such as suction parameter, buoyancy parameter, Prandtl number, body-radius parameter and other driving parameters. The effects of dimensionless parameters on the velocity and temperature distributions are presented graphically. It is found that a small suction or blowing can play a significant role on the patterns of flow and temperature fields.

HIGH DOF INTERPRETED EMG DATA BASED PROSTHETIC ARM

Authors:

DOI NO:

Abstract:

EMG is the detection of the electrical activity associated with muscle contraction. It is obtained by measurement of the electrical activity of a muscle during contraction. EMG signals are directly linked to the desire of movement of the person. Robot arms are versatile tools found in a wide range of applications. While the user moves his arm, (EMG) activity is recorded from selected muscles, using surface EMG electrodes. By a decoding procedure the muscular activity is transformed to kinematic variables that are used to control the robot arm. This patent is the  innovative design of a new low-cost series elastic robotic arm. The arm is unique in that it achieves reasonable performance for the envisioned tasks with high DOF. There are numerous dimensions over which robotic arms can be evaluated, such as backlash, payload, speed, bandwidth, repeatability, compliance, human safety, and cost, to name a few. In robotics research, some of these dimensions are more important than others: for grasping and object manipulation, high repeatability and low backlash are important. To develop the articulated  innovative arm design of the robot with high DOF equations were developed for both forward and inverse kinematics. Forward kinematics gives the location of the end effector in the “universe” frame. The inverse kinematics gives the joint angles needed in order for the to the robot arm reach the goal frame. This high DOF based prosthetic arm operates according to EMG database. The EMG signal is obtained for different users for different arm  movements  using signal acquisition system. The EMG signals are used as input to the Microcontroller and converted to digital ones in the comparator. According to these signals the program built in the microcontroller make decisions to control the motors to drive the prosthesis arm.

Reliable Best-Relay Selection for Secondary Transmission in Co-operation Based Cognitive Radio Systems: A Multi-Criteria Approach

Abstract:

Selection of Relay for unlicensed transmission in cooperation based cognitive
radio systems is an essential area of research which ensures the transmission
performance of the secondary system & at the same time maintains the transmission
behavior of the licensed network with respect to the quality-of-service (QoS).So far we
have studied Signal-to-Interference-plus-Noise Ratio (SINR) of a relay node as the sole
parameter to judge the BEST relay in the existing research works. This time we have
proposed few other important parameters like Reliability and Relative Link Quality
(RLQ) of a relay node as seen from the receiver, in order to select the Reliable BEST
relay in a more accurate manner from the rest of the lot as the authors believe that for a
faithful transmission, the selected best relay should be reliable along with other
parameters. We have carried out ample simulation study to find out the reliable best
relay applying our proposed fuzzy logic-based scheme. The implementation of the
suggested system is verified with the earlier proposed schemes, i.e., fuzzy logic-based,
SINR based and without relay have been studied holistically through the Secondary
Outage Probability & Bit Error Rate (BER) simulation results.

equation of fractional order with the aid of a suitable composite transformation and
then the methods are applied to construct the solutions. The methods successfully
provide many new and more general closed form traveling wave solutions. The
obtained solutions may be more effective to analyze the nonlinear physical
phenomena relevance to science and engineering than the existing results in
literature. The performance of the proposed method is highly noticeable and this
method will be used in further works to establish more entirely new solutions for

Currently, Fuzzy analytic hierarchy process (FAHP) proves to be an advantageous scheme for multiple criteria decision-making (MCDM) in fuzzy conditions. This paper provides FAHP-based relay node selection scheme that prioritizes the fuzziness of the decision makers during the relay node selection procedure. Numerical examples and simulation study, both are carried out to find out the best relay. The simulation study reveals the fact that the proposed scheme outperforms the existing systems.

The divide by 32/33 dual modulus prescaler using 2/3 prescaler and 4/5 prescaler consumes 1.03mW and 0.85mW power from 1.2V and 1V respectively. To further improve speed and reduce design complexity with low power consumption a pseudo divide by 32/33 dual modulus prescaler is proposed. According to simulation results the pseudo divide by 32/33 dual modulus prescaler reaches a maximum 9.2 GHz working frequency at 1V with a 0.17mw power consumption.

From few decades conventional PID tuning rules are used for analyzing any complex system. But these rules did not give always a satisfactory result as our requirement. That’s why a better algorithm was introduced which is actually based on Evolutionary Computation method. This methodology provides a very high accuracy in the response in comparison with other tuning rules.From thevery past, PID controller has been very popular and is being used in maximum industries. So, there’s always a need to control the accuracy and efficiency of the controller because depending on this controller the whole industry might be functioning. If any large error occurs in the controller (PID), the functioning of the industry might be hampered. That’s why using PSO algorithm for determining the PID parameter is a good idea to get an efficient and accurate output. This approach may help in future to improve the performance of PID controller and also may help to reduce errors encountered in the industries.

Biomethanation – A source of clean alternative fuel for Electric Power Generation and sustainable development in rural India

Authors:

DOI NO:

Abstract:

Biogas is obtained from biomethanation of biomass waste. The present work aims at a detailed discussion of the different factors affecting the perforation of biomethanation process. Some case studies have been presented to show the techno-economical feasibility of different plants, based on different locally available biomass. In most of the cases plants are installed against adequate financial support with subsidy, but the performance of the plants is being affected due to lack of technical knowhow. Effects of different process parameters such as PH-value, temperature, C/N ratio on biogas generation, needs to be taken care of to ensure maximum generation rate with highest yield. Since biomass is locally available, harnessing energy from it may be a probable solution to end the energy crisis in rural areas which are remote from the power grid, thereby providing immense potential for electrification, application to a large number of industries and last but not the least domestic purpose using Biogas.

Rprop Based Noble Blind Channel Equalization Algorithm for QAM Signal

Authors:

DOI NO:

Abstract:

In this paper, authors have considered the issue of slow convergence and moderate Bit Error Rate (BER) of Constant Modulus Algorithm used for channel equalization. Constant Modulus Algorithm (CMA), an extensively used gradient descent based unsupervised algorithm for QAM Signal, suffers from the poor convergence property as well as poor BER. Two novel blind equalization algorithms have been proposed which overcomes the problem of slow convergence and poor BER associated with CMA. Proposed algorithm incorporates modified CMA-like error function based on mean forth error criteria into Rprop frame work. Matlab Simulation of the proposed Rprop Based Improved Constant Modulus Type (RICMT) algorithm offers better result in terms of convergence, inter symbol interference (ISI) and bit error rate (BER) in a linear channel as well as for nonlinear channel in comparison to the CMA Equalizer for noisy environment.

To Negate the influences of Un-deterministic Dispersed Generation on Interconnection to the Distributed System considering Power Losses of the system

Authors:

DOI NO:

Abstract:

Now a days, the rapid need for electrical energy all over the world has put electrical power system under great stress. Due to day by day decrease in available conventional energy sources, researchers are shifting towards non-conventional energy resources or Dispersed generation (DG). DG is becoming a feasible alternative to overcome the power deficiency due to reduction in power losses, system reliability, and availability of power at consumer’s premises. With this need of DG, it’s important to analyze the adverse impact of DG on distributed power system. This research analyzes the effects of induction generator and synchronous generators on distribution system. The main outcome and objective of this research is to find optimum type, size and placement of DG to be injected in distributed system in order to have minimum impact on power losses of the system. By using globally renowned and modern software Electrical Transient Analyzer Program (ETAP) and taking Rahman Baba electricity distribution network as a test case. After analyzing, the results show that injecting DG has positive impacts on power losses at certain buses while 30% of power losses were decreased when induction generator as a DG unit was integrated with the distribution network in the optimum location. Also positive impacts of DG unit on power losses has been seen by injecting undeterministic small amount of synchronous generator as a DG unit and by increasing cross-sectional area of the conductor has showed much improvement in power losses.

Abstract:

The speed control is an interesting and important term in control system engineering. Speed of the DC servomotor has to be varied according to application requirement. According to requirement suitable controllers and algorithm are use to achieve best control over speed. PID controller is a well known controller which is used in feedback control in industrial application. But in some industrial application the speed control with PID controller is not able to achieve the perfect control due to non linear element present in the system. Therefore in this research the Particle Swarm Optimization based PID controller and Hybrid Fuzzy Logic Controller are use to overcome this problem.

Design approach to a wound rotor induction motor towards optimization

Authors:

DOI NO:

Abstract:

About 88% of the driving power is produced by 3-phase and single-phase induction motors. In most part it is by squirrel-cage motors, only a small fraction by the slip-ring or phase-wound type. It is because the cage-type motors are relatively inexpensive. But they suffer from low p.f. operation and low starting torque which cannot be manipulated by inserting resistance in the rotor circuit. Also, this type of induction motors is not easily speed-adjustable. Though a little more expensive, the slip-ring type induction motors do not have these disadvantages. Therefore, they are used as speed-adjustable drives and for drives where heavy duty starting is involved. The design of any kind of power equipment should be made cost-optimally in the present day competitive market. A new approach to reaching optimal solution has been shown in this paper by the method of sequential searching with respect to the chosen design variables. Also, another design has been made following a hybrid of analytical and synthetic approach. The design variables have been chosen from designers’ experience. In contrary to the popular belief that there is no need for going in for complexity of optimal design, the quasi-optimal solution may be obtained by the designer from his accumulated experience, we find that the idea is wrong. The optimal design approach saves a lot of money.

Abstract:

Abstract
Exponential growth in cellular services has fueled the penetration of
telecommunication industry in rural areas of Khyber Pakhtunkhwa (KPK). However,
the scarcity of electricity at such localities has limited the growth and operation of
network operators. One solution to overcome the problem includes utilization of
diesel generator along with grids for continuous supply. However, this solution
requires high fuel consumption, extensive maintenance and elevated delivery cost,
which makes its operation less efficient. Photovoltaic (PV) systems are anticipated to
solve the problem by providing necessary power at increased reliability and
performance. This paper proposes the use PV system along with grids at rural areas
of KPK to increase the operation and reliability of base stations (BTS’s). Feasibility
of the proposed design is checked via Hybrid Optimization Model for Electrical
Renewable(HOMER) Software. It is shown that the proposed PV grid hybrid system
is more efficient as compared to the diesel and standalone PV system at the rural cell
sites in KPK, Pakistan.

The production of electric power from the foot step movement of the peoples and the pressure exerted during walking which is fritter away, is the main theme of this paper. The mechanical power transformation into electrical power as the pressure exerted by the footstep and by using transducers is basically called as “Foot step power generation system”. Power is produced by the power generating floor and it is basically the production of electrical energy from kinetic energy. As today electricity demand is increasing and it is unable to overcome this global issue by using the traditional power generating sources. Demand and supply gap is the major issue of energy crisis.
The main aim is to overcome the power crisis throughout the world although it is not enough to fulfill over excessive demand of electrical energy but it will be able to change and decrease reliance on old method of generating electricity. We can generate 1 megawatt of power if we have a 100 floor, as we are able to model a power production floor which can generate up to 1000 watt on just twelve footsteps means one unit and it is capable to generate 10000w power for just 120 footsteps. It can be installed on road side footpath, parks and jogging tracks and many other public place, airport etc. and have great impact of this and will create great difference in the electrical power generation system.

Abstract:

Pavement distresses such as Rutting, fatigue, Potholes and moisture induced damage are common Pavement distress that causes the pavement failure at early design life of pavement which causes huge financial constrain to national exchequer. Since developed countries are adopting pavement preventive technique as compared to pavement reconstruction. This strategy of pavement prevention can be beneficial for developing countries to enhance serviceable life of Pavement, which can save huge amount of Cost. In this research four different Pavement section were selected based on the type of treatment applied on that specific section along Islamabad-Lahore motorway (M-2), Pakistan. The first pavement section was a blend of 15 percent Rap and 7 percent crumb rubber (Rap 15%, CR 7%), the second pavement section was a blend of asphalt with crumb rubber modified bitumen as binder (Rap 0%, CR 7%), the third Pavement section was a blend of 15 percent Rap with grade 60-70 bitumen as binder (Rap 15%, CR 0%), the fourth section was asphalt concrete wearing course with grade 60-70 bitumen as binder(Rap 0%, CR 0%). Cores were extracted from the selected four section which were further evaluated at laboratory for pavement distresses such as fatigue and damage induced to pavement due to moisture at lab. It was concluded that section one performance against fatigue was substantially better than other pavement sections while section one performance against moisture induced damages was lesser as compare to other section. Moreover, it was observed that resistance against moisture damage was considerable in section 3.

Abstract:

As heat transfer device, heat exchanger has gained wide applications across different areas of domestic and industrial set-ups. Various studies have been carried out to analyze and predict its performance. However, one major problem that limits heat exchanger performance is fouling effect. Based on this, different studies and approaches have been employed by different researchers on reduction and mitigation of fouling. The following review paper furnishes the different major analysis carried out by different researchers on the effect of fouling of shell and tube type of heat exchanger. The study found that despite of the existing models developed towards understanding fouling, there is no single model that has provided an accurate prediction of fouling in tube and shell type heat exchangers. Further to this, majority of the study results only pointed to small scale laboratory test schemes and there is absence of sufficient data that predicts actual (real life) service performance.

Noble methods to Prevent pounding between Adjacent Buildings

Authors:

DOI NO:

Abstract:

Pounding refers to the collision of adjacent structures during strong ground motions. Actually when an earthquake occurs, the structures which are having different dynamic properties vibrate out of phase and collide with each other resulting in heavy damage of life and property. The main reason behind pounding between structures is the insufficient separation distance provided between the buildings. Different countries having different codes provide different rules and regulations regarding the separation distance that needs to be given between the structures to prevent pounding but the insufficient land area and high land prices especially in metropolitan cities, the separation distance is bound to be given very less in order to have effective use of land area during construction. So, in order to prevent the structures from colliding with each other, some cost effective mitigation measures like RCC cross bracings and RC shear wall have been discussed in this study. SAP2000 v19 software has been used for modelling and analysis of the structures. This study includes two types of frame structures i.e. (i) bare frame structure and (ii) structure having infill walls in the form of diagonal strut in it. The mitigation methods such as use of shear wall and bracings proved to be effective in all the cases. Also the best location of bracings and shear wall has been studied by placing them at various locations in the structures and observe the amount of displacement that is being reduced.

Similarity Based Feature Weighting for Inter Domain Classification of Text

Authors:

DOI NO:

Abstract:

Intra domain supervised classification of online reviews is vastly analysed by current studies. At the same time, the level of performance declines when training is performed with one domain and testing with reviews of a different domain. The main fact behind this reduction is the domain distribution difference and the feature vector difference. Also the semantic of each word in a corpus differs based on its usage in domains. The objective of this study is to propose a new similarity based feature weighting technique for text reviews for enhancing the accuracy of inter domain classification. Different training and testing domains are weighted by proposed probability based statistical techniques for the classification by Support Vector Machine (SVM) and Transductive Support Vector Machine (TSVM). TSVM performs much better for this cross domain classification. The fact behind the performance of TSVM is its Transductive learning even with the small training set. The correlation between source and target domain and its influence on classification accuracy are analysed in detail using the outcome of existing feature weighting and proposed weighting techniques.

Investigation of Self – Dithering Technique on MASH 1-1-1 and Third Order Error – Output Feedback Modulator

Authors:

Abstract:

Digital delta sigma modulator (DDSM) is integral part of the divider of PLL based fractional –N frequency synthesizer. The output of DDSM is notorious for spurious tones in its output. Generally, the inherent periodicity of DDSM is considered the main reason for generation of these tones. The recent researched focus on the role of linear feedback shift register (LFSR) based pseudorandom dither which is added with input of DDSM to break its periodicity. Since, an ideal random sequence cannot be realized; the periodic nature of LFSR dither itself is considered a sour to energize these spurious tones appearing at the output of synthesizer. The self-dithering technique is claimed to perform the efficient dithering of the input of DDSM without using LFSR. In this paper we investigate the use of self-dithering technique with MASH 1-1-1 & EOFM mash that is claimed to be as effective as LFSR dither.

A New Image Steganography Method using Message Bits Shuffling

Authors:

DOI NO:

Abstract:

Steganography has been considered as a technique of message hiding within another carrier multimedia data. Messages in the form of image (with embedded handwritten or typed texts) are often embedded in several ways within another image in image steganography. DCT based schemes are undertaken in the frequency domain methods in addition to usual plain text message embedding. Most of the message image hiding techniques embeds image bit string without considering any shuffling schemes to deal with the said string before embedding. Present work targeted to incorporate message hiding essentially with shuffled and re-shuffled bit strings in different ways prior to DCT operation. A new method has been proposed with these shuffling schemes to enhance the security level of the encryption. Investigations with the proposed image steganography method show that the new methods performed better than normal image steganography techniques without shuffling schemes. Performance of the proposed method is evaluated using Peak-Signal-to-Noise Ratio (PSNR) and Mean Square Error (MSE). Results show that the shuffling bit steganography method outperformed the common DCT based schemes without shuffling.

Authors:

DOI NO:

Abstract:

Architecture Evaluation is a means to reduce risk and save cost. It holds the key to success of the system being developed. Various evaluation methods exist which have specific objectives and basis and all contribute to enhance product quality. In this paper a Complexity UML Based Architecture Evaluation (CUBAE) approach is proposed to evaluate the architecture of a system built using CBSD approach. . The proposed approach estimates the complexity of the architecture from the UML representation of different views of the architecture. Earlier works on complexity measures of UML representations found in literature are used along with proposed measures for complexity calculation. This complexity measure may be used to assess and compare architecture representing the same system along with other measures like modifiability and different quality attributes used for evaluating the architecture.

Prediction of Heating and Cooling Load to improve Energy Efficiency of Buildings Using Machine Learning Techniques

Authors:

DOI NO:

Abstract:

Global warming has been a severe threat to humanityand greenhouse gases emitted from power plants is one of the major causes of global warming. In this paper, we use machine learning to incorporate energy efficiency techniques to buildings by predicting the Heating and Cooling Load using eight input features.Heating load is the amount of heat per unit time that a building needs to maintain the temperature at an established level whereas Cooling load is the amount of heat per unit time that must be removed. Heating, cooling, and ventilation systems are used to handle heating and cooling load. We train four regression (linear regression, Lasso, Ridge, and Elastic-Net) and three gradient boosting models (GBM, XGBoost, and LightGBM) and test them to compare their performance using 768 rows of data of residential buildings. We observe that the gradient boosting models perform significantly better than the standard regression models for both Heating Load and Cooling Load. XGBoost achieves the highest R-squared score of 0.99 for Heating Load and 0.99 for Cooling Load. From the results of this study, we conclude that machine learning techniques can predict Heating Load and Cooling Load with high accuracy. The obtained Heating load and cooling load values can be used to install efficient heating, cooling and ventilation systems and thus reduce both energy consumption and money.

Overhead Transmission Lines Analysis Considering Sag-Tension under Maximum Wind Effect

Authors:

DOI NO:

Abstract:

Grid stations get generated power from power stations that are ordinarily far; continuous consumption or use of electric power has expanded in most recent couple of years. Transmission system is the system by methods for which power is transmitted from place of generation to the consumers. Overhead wires or conductors are the medium used for transmission of power. These wires are visible to wind, heat and ice. The efficiency of the power system increases if the losses of these overhead wires are minimal. These losses are based on the resistive, magnetic and capacitive nature of the conductor. It is necessary to create or make proper design of these conductors accompanied by proper installation. To balance the working and strength of overhead transmission line and to minimize its capacitive effect the conductors must be installed in catenary shape. The sag is required in transmission line for conductor suspension. The conductors are appended between two overhead towers with ideal estimation of sag. It is because of keeping conductor safety from inordinate tension. To permit safe tension in the conductor, conductors are not completely extended; rather they are allowed to have sag. For equal level supports this paper provides sag and tension estimation with two different cases under maximum operating temperature 45 °C. To calculate sag-tension estimation of ACSR (Aluminum Conductor Steel Reinforced) overhead lines twoe different cases are provided with no and high wind speed effects. Four different span lengths are taken for same level supports. ETAP (Electrical Transient and Analysis Program) is used for simulation setup. The results shows that wind effect has great impact upon line tension and with addition of wind speed the sag of line remains same while tension altered.

Abstract:

As beam steering antennas are being an ideal solution for many satellite applications, this paper is concerned on the design of a 16-element linear array antenna, using an RT Duroid substrate at 20.2 GHz for Ka-Band satellite communications. The design is initiated with single element and thereby incremented in steps to 2, 4, 8 and 16 elements. An optimum inter element spacing of 0.73λ is considered for the purpose of fulfilling the desired scanning requirement. Performance analysis of the proposed antenna is analyzed mainly in terms of Relative Side Lobe level (RSLL) and Beam steering. To synthesize the antenna, weights of the antenna are considered according to Taylor’s amplitude distribution along the antenna aperture to attain a relative side lobe level of -25dB. The proposed 16-element linear array antenna achieved a maximum gain of 19.5dB and the main beam direction can be switched up to 50o (±25o) without introduction any grating lobes. In addition to, other relevant antenna parameters such as reflection coefficient, VSWR, gain and efficiency of single, 2, 4, 8 and 16 element antennas are compared. The proposed linear array antenna is designed using Ansoft HFSS.

Abstract:

Portable water is a gift of God, which is used by human beings both for domestic and industrial purposes, but when it is polluted by certain reasons it become useless and adversely effects human health, aquatic life and threats the ground water. There are many sources of water pollution and Industrial pollution is one major source and concern for today’s world because toxic substances and chemicals used as raw products in industries is being discharged as residual to the water bodies if not treated. The HIE is no exception, where different industries are indiscriminately releasing their untreated effluents to open nallah, which ultimately makes its way into river Kabul while passing through urban and rural areas of Peshawar. The river Kabul water is widely used for irrigation purposes and is affecting the human and marine life because of the untreated toxic effluents.
The study deals with the estimation and characterization of pollutions load discharged by the HIE and possible solutions to control these effluents at source i.e. at individual industrial level or at a Combined Effluent Treatment Plant (CETP). The study concluded that toxic effluents with high BOD, COD and TSS along with number of other heavy metals are released untreated. These effluents cannot be treated at source due to high cost and non-availability of land in existing developed industries. Also it is not advisable to install individual treatment plants due to lack of technical knowhow and high maintenance costs. The solution for this is to install a CETP at a suitable location on common benefit and maintenance cost mechanism.

Abstract:

Wireless Body Area Sensor Network (WBANs) are used to measure the biological parameters of a human body in a critical health situation. Sensors use an antenna and electromagnetic radiations to drive the response towards the sink node. Our research focuses on the overheating problem of body tissues due to the electromagnetic field generated by electromagnetic radiations. When sensor nodes continuously send and receive the data, it not only influences the communication between the nodes by stimulating high attenuation for signal transmission, but also conduits various health problems. These health issues may include reducing blood flow, affecting the enzymatic reactions, brain tumor, damaging the sensitive tissues and leading to tissue cancer. The exposition of such issues are addressed in our research called iBTTA (Improved Body Tissue Temperature Aware)routing scheme, where not only the temperature of a body tissues is controlled under the threshold value but significantly improves the performance in terms of its throughput, end- to- end delay and transmission loss. The scheme is an extension of our previously published scheme BTTA. The validation of our scheme iBTTA is done through comparison with already existing techniques SIMPLE (Stable Increased-throughput Multi-hop Protocol for Link Efficiency in WBANs) and LAEEBA (Link-Aware and Energy Efficient scheme for WBANs). In iBTTA we have improved the problem of the body tissues temperature, utilization of battery power and load balancing techniques in WBANs.

Abstract:

In late years, camera identification methods have drawn attention in the area of digital forensics. To detect the source camera through which the picture is caught, Photo-Response Non uniformity (PRNU) noise is utilized as a camera, impression, as it is a particular component that recognizes pictures taken from the comparable cameras. This paper introduces a camera identification technique which is based on Krawtchouk Moment invariant features. The Photo Response Non-Uniformity (PRNU) noise is a type of sensor finger impression, which permits to extraordinarily distinguish the camera that took an image. It is estimated from the denoised images using a denoised filter. Then estimate the Krawtchouk Moment invariants from the PRNU noise pattern. The Krawtchouk Moments are invariant to scaling, translation, rotation, and shear. These invariants are fed to Fuzzy Min-Max Neural Network with Compensatory Neuron (FMCN) and by performing ten-fold cross-validation technique, verification is made out. The experimental results show that the proposed technique achieves an average accuracy of 93.3% for first experiment and 98.3% for the second experiment.

Abstract:

Ground granulated furnace slag is a waste material which is rich in Calcium. Aim of this study is to observe the effect of mixing of ground granulated blast furnace slag as a replacement of cement in concrete. The study is conducted on M-30 grade concrete. The cement is replaced partially by the ground granulated blast furnace slag to obtain a cost-effective mix. The concrete mixes are prepared by replacing the cement by 15%, 30%, 45%, 60% and 75 % ground granulated blast furnace slag. The tests are performed to know the compressive strength, flexural strength and workability of concrete. Non-destructive tests like rebound hammer test and ultrasonic pulse velocity tests are also performed to understand the post hardening characteristics of the concrete. It is found that the replacement of cement GGBFS reduces the initial strength of concrete but increases the ultimate strength if mixed in optimum amount. The optimum percentage of ground granulated furnace slag in M-30 concrete is found to be 45%. The workability increases as the amount of GGBFS is increased in the mix. The post hardening tests show the better performance of concrete at 30% and 45% mixing of GGBFS in concrete.

Abstract:

Social media data made real world like a web of data which is highly categorical in nature. Data having categorical attributes are omnipresent in existing real world. Clustering is an effective approach to deal with categorical data. However, partitional clustering algorithms are prone to fall into local optima for categorical data. A novel approach of ABC K-modes has been proposed to address this issue but acceleration issue of this algorithm was still a challenge for it. In this paper, we address this challenge to reduce the acceleration factor of algorithm and proposing a novel modified ABC K-modes approach which we refer as N-ABC K-modes approach. In our approach, unlike existing ABC K-modes we introduces different attribute matrix for each data sets. In further step, we apply XOR operation to combine the matrix of similar attributes. In last phase, dissimilar data would form a cluster and we apply clustering follow by searching on this cluster. The performance of New ABC K-modes evaluated by a series of tests and experiments over real time streaming social media data like twitter and facebook in comparison with that of other popular algorithms for categorical data.

The recent paper, we enucleated this method for each of the following Couple Boiti-Leon-Pempinelli equations system, DSSH equation and fourth-order nonlinear Ablowitz-Kaup-Newell-Segur (AKNS) water wave dynamical equation. The prominent competence of this method is to naturalize the way of solving systems of NLEEs. Moreover, we can see that when the parameters are ascribed to the particular values, obtain solitary wave solution from the exact travelling wave solution. The obtained new solutions have a wide range of inflictions in the field of physics and other areas of applied science. To perceive the physical phenomena, we have plotted coupled with some 2𝐷 and 3𝐷 graphical patterns of analytic solutions obtained in this study by using computer programming wolfram Mathematica.

Performance Enhancement of Intermediate Temperature SOFC Cathode by Nano-Composite Coating

Authors:

DOI NO:

Abstract:

The La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) is categorized as a mixed ionic-electronic conducting oxide has found significant attention as cathode material in solid oxide fuel cells (SOFCs) operating at intermediate temperatures, 500-850oC. The performance of LSCF electrode is limited by the oxygen ion transport process at the surface, which is the rate determining step of oxygen reduction reaction. To enhance the oxygen surface exchange process of LSCF electrode, a nano-composite electrolyte is introduced at the surface, which substantially improves the electrochemical performance. The electrical conductivity relaxation technique (ECR) has been used to study the oxygen surface exchange kinetics of bare LSCF and coated with a mixture of Ce0.8Sm0.2O2-δ (SDC) and ZrO2.Y2O3 (Yttria-stabilized zirconia -YSZ) nano-powders in three different weight ratios, SDC:YSZ = 0.5:1, 1:1, 1:0.5. The chemical oxygen surface exchange coefficient kchem of surface modified specimens were derived with a one-parameter fitting process. The results show that the oxygen surface exchange kinetics of LSCF is affected by the SDC-YSZ coating and the average kchem values of SDC-YSZ coated LSCF increases by a factor 2 to 8 from 650 to 850 oC, respectively. It has been concluded that the high ionic conductive oxide coating improves the oxygen surface exchange kinetics of underlying LSCF mixed conducting oxide and consequently enhances the performance of electrochemical device such as solid oxide fuel cell.

Ultra Stable and Highly Efficient Nickel Nanotube Catalyst for PEMFC Electrochemical Oxygen Reduction Reaction

Authors:

DOI NO:

Abstract:

The oxygen reduction reaction (ORR) in proton exchange membrane fuel cell (PEMFC) having sluggish kinetics at cathode side requires highly active and low cost catalyst. Conventionally, platinum (Pt) is considered to be the most feasible and active catalyst for ORR at cathode, however,it’s far expensive to meet the demand for commercialization. Herein novel non platinum group metal (N-PGM) nickel (Ni) nanotubes were prepared by using solvothermal method using transition metal precursor forming Ni ZeoliticImidazolateFramework (Ni/ZIF). Ni nanotubes were obtained after carbonizing Ni/ZIF at 850oC under inert nitrogen atmosphere. The morphology and motif were extensively studied by conducting XRD and SEM. The electro-catalytic performance of Pt/C catalyst, pristine Ni/ZIF and Ni nanotubes were investigated by Linear Sweep Voltammetry (LSV) performed with Rotating Disk Electrode (RDE) in alkaline medium. The Ni/ZIF shows a current density of -1.4 mA/cm2and Ni nanotubes depicts current density of -2.7mA.cm-2 and an over potential of -0.27V Vs Saturated Calomel Electrode (SCE). RDE Results were obtained at 400, 800, 1200 and 1600 rpm in 0.1M KOH solution. The evaluation shows that Ni nanotubes own extraordinary electro-catalytic behavior towards ORR activity and Ni nanotubes has potential to be used for PEMFC application.

Influence of Dual Layer Silica Nanoparticles Coating on the Performance Enhancement of Solar PV Modules

Authors:

DOI NO:

Abstract:

The Porous silica nanoparticles deposited on the glass as well as bare silicon wafer substrate to obtain super hydrophilicity and antireflectivity. The coating is performed by using aerosol impact deposition system using silane, air and helium as precursor gases. The desired coating thickness over the substrate surface is achieved by tuning the RF power, pressures ratio of reaction to deposition chamber and maneuvering of silane flow rate, helium and air mixture. Scanning electron microscopy reveals the particle size of 12.6 nm, whereas, atomic force microscopy (AFM) is deployed to study the coated film surface topology. This indicates outstanding antifogging and super-hydrophilic properties due to surface roughness and nano-porosity. Moreover, the coated surface graded index increases the transmissivity from 90% to 99.2%. Such enhancements are much favorable for the solar PV applications.

A Secure and Efficient Scheduling Mechanism for Emergency Data Transmission in IOT

Authors:

DOI NO:

Abstract:

Internet of things (IOT) enables electronic gadgets to communicate with the server and each other, enabling them to share crucial information. With the advancement in the technology, more and more devices are added to the network of IOT every day. In the era of smart cities, the amount of data being transmitted is immense. While transferring such a huge amount of data, the system has to prioritize the data being sent based on the importance, such as medical and fire safety information. Lack of efficient scheduling algorithms leads to inappropriate delivery of emergency packets, thus rupturing the functionality of the system. Also, the data sent over the network has to guardagainst attacks over the channel. To overcome these drawbacks, a scheduling algorithm named Efficient data emergency aware packet scheduling scheme (EARS), enhanced with data security using Elliptic curve cryptography is proposed in this paper. In EARS, each packet has a description of its priority and the deadline before which it has to reach the sink. This enables easy identification of the emergency nodes. Further, in order to reduce the total number of transmissions in the network, the normal data packets can be network-coded and sent to the destination. This will reduce the congestion in the network. The proposed method is compared with the existing state of the art techniques and the results produced outperformed the exciting methods.

Two Step Verification technique For Detection of Malicious Nodes in Wireless Sensor Networks

Authors:

DOI NO:

Abstract:

The wireless sensor network is the application oriented network which performs task of monitoring and object tracking. The wireless sensor node has the architecture which involves wireless interface for the communication. The design of the wireless sensor network depends upon the significant of application, cost and type of hardware. The architecture of WSN is dynamic due to which security and energy consumption are the major constraints. The Sybil attack is the attack which is possible in wireless sensor networks and it affect network performance. The attacker node generates multiple identities to attract network traffic and leads to denial of service in the network. In this research work, two step verification technique is proposed for the detection of malicious nodes from the network. In the two step verification technique, the cluster heads detect the node as untrusted if its energy consumption is abnormal. The extra observer nodes are deployed in the network, which observe network traffic. On the basis of network traffic observations, the node is declared as trusted or untrusted. When the cluster head and observer node both declare on node as untrusted node, then that sensor node will be considered as malicious node. The experiment is conducted is NS2 by considering certain simulation parameters. It is analyzed that two step verification technique detect malicious nodes successfully and it also leads to improve network performance in terms of Delay, PDR and Packetloss.

Performance Analysis of sub interleaver for turbo coded OFDM system

Authors:

DOI NO:

Abstract:

4G LTE / 5G is the high speed communication system developed for smart phones and other mobile devices in the recent era. The current level of mobile device usage and data exchange over the internet has raised the need for such a fast and secure communication system. One of the important feature in an LTE system is the use of OFDM technique, owing to its advantage namely robustness to multipath fading and interference. This paper proposes an improved OFDM based 4G LTE system fused with turbo code encoding technique to further reduce the bit error rate over noisy real-time channels. The proposed turbo codes system has a hybrid two stage interleaver which is a combination of 3GP interleaver and block interleaver. This interleaver reduces the time required for interleaving processing while maintaining the BER criteria up to the levels. The traditional decoder has been replaced with a threshold-log-MAP algorithm based interleaver for improved noise tolerance. The proposed system has been tested over various channels like Rayleigh, rician and nakagami channels. The experimental results prove that the performance of the stem has improved in comparison by the addition of turbo codes.

Flag Com: Energy Efficient Secure Routing Protocol

Authors:

Abstract:

Mobile communication has become all pervasive in the present day scenario and has gained ubiquitous importance in everyday life. The radio spectrum, which form foundation of mobile communication is a physically limited resources, and is already reaching the threshold of saturation. Co-Operative communication is expected to be the next big change in mobile communication systems. The radio spectrum scarcity, which is prescribed to be reality sooner than we may realize, needs immediate addressing and cooperative communication provides hope of offering solution towards resolution. While looking at radio spectrum scarcity co-operative communication is a hope to resolve this problem. There are however, lot of issues like security, energy consumption, instability of nodes etc, which should be resolved before execution of co-operative communication. In this paper we suggest a protocol Flag-com, which may take care of all these issues. This protocol has been designed in such a way that the major portion of packet processing is done only on source and destination node. This will resolve not only security issue but will also reduce consumption of power at the relay nodes. It will also keep a tab on the movement of relay nodes so that proactive measures like searching and selection of new relay nodes can be done before the relay node moves out of the range.
Path selection is another major issue in co-operative communication. Since the transmitted power from any node is very low so effect any type of attenuation will affect the communication. Attenuation in a wireless or mobile network can be divided in two parts (i) attenuation due to nature (ii) attenuation due to interference. Attenuation due to nature cannot be reduced. In this paper we have dealt with both, Markov model has been used to predict the effect of nature on transmitted data packets and tabu search is used to find the path having lowest interference.

Abstract:

Oxidized poly(acrylonitrile) fibers (OPF) upon thermal treatment of poly(acrylonitrile) has been achieved and has been used as raw material to produce carbon fibers. The influence of fibers on the mechanical properties of the composite of polymer matrix reinforced by fabric were analyzed in this study by using three types of advanced fibers. For this purpose, 13 composites of epoxy matrix reinforced by fabrics of carbon fiber, Kevlar and Glass fiber with OPF were prepared by manual padding of 4 layers with different arrangements. For the preparation of composite epoxy resin Bisphenol F and polyamine as a hardener were used with resin to fiber ratio of 60:40. The tensile properties and the fractured surface of the composite samples were studied. Results of the study showed that by increasing the ratio of OPF to carbon, to Kevlar and to Glass fabric, the tensile strength decreases but for the samples in which OPF is more than 50% the fracture strain is increased. The results of cross-sectional fracture showed that composite made with a carbon fiber fabric, Kevlar and Glass fabric with OPF have lateral, explosive and edge delamination failure mode occurs on the other hand by increasing the OPF content to composite transverse failure mode happens.

Abstract:

Biopolyols have been synthesized from Oil Palm Mesocarp fibre (PM) as monomer feedstock to be crosslinked as polyurethane, PU foams (PMF). This study is conducted to determine the effects of PM as waste fibre filler on the performance of PU foam. A ‘one-step method’ technique is used to crosslink the monomer and disperses the PM waste filler with vigorous stirred and left to cure at room temperature in an open cylindrical mould. Increasing the PM waste filler percentage from 1% to 9% on PU foams namely as PMF1 – PMF9 respectively have shown dramatic enhancements in physical, thermal and mechanical properties over the neat PMF without compromising foaming kinetic, density, porosity, and processibility. The compressive strength of PMF slightly increased as the increments of the waste filler percentage content. TGA result indicated that PMFs displayed almost the same trend in thermal stabilities and thermal degradation temperature. As comparison with PMF, the PMF1 – PMF9 were markedly increased the degradation temperature at three different decomposition stages as neat PMF. In addition, fourier transform infrared (FT-IR) analysis revealed that the incorporation with PM waste filler did not changed any chemical group of polyurethane.

The presence of active institutional investors in monitoring and controlling the management decision making are focus towards public listed firms invested by government fiduciary bodies (Top-6). Institutional investors who are purchased and held the corporate bonds and sukuk rather than individual investors might be a significant factor to bond performance especially on yield to maturity (YTM). As institutional ownerships, supposed they will actively involve in monitoring and pressure more sensitive towards performance of conventional bonds and sukuk. By considering to this issue, the objective of this paper is to investigate the impact of equity ownerships towards bond performance particularly on its yield spreads. Data are obtained from firm issuers’ annual reports, Bondinfo Hub of Malaysia Central Bank, Department of Malaysia Statistics and Bloomberg for the period of 2003 to 2014. Unbalanced Panel data approach is utilized for multivariate regression model covers for OLS, fixed effects and random effects. Results revealed that the presence of top-6 institutional investors have a significant negative impact towards yield spreads. Debt issuers are recommended to offer high bond issuances to this investor since their presence could mitigate cost of defaults by active cost monitoring and controlling which support the agency cost of debt theory.

Abstract:

Geopolymer (GP) is a new generation of binder material in construction industry. Production of ordinary Portland cement (OPC) utilizes extensive energy as well as it emits large amount of CO2 into the atmosphere when compared to GP production. This paper focuses on the effect of polyvinyl alcohol (PVA) fibers, sand/fly ash and water/ geopolymer solids ratios on the workability and compressive strength of fly ash based geopolymer composite. Curing temperature, NaOH molarity and Na2Sio3/NaOH were kept as 60ᵒC, 8M and 2.5 respectively. Total of 2% (v/v) PVA fibers with cut length of 8mm and diameter of 0.04mm were utilized. Furthermore, sand/fly ash and water/ geopolymer solids (W/GP) ratios were varied in a range of 0-0.8 and 0.22-0.26 respectively. Results were evaluated with the help of response surface methodology. Reduction in workability was observed with the addition of fibers in matrix. Moreover, increase in sand/fly ash ratio caused decrease in workability and vice versa for the increase in water/ geopolymer solids ratio. Furthermore, Inclusion of fibers did not show considerable change in the compressive strength of geopolymer, however, when the workability of the matrix mixture kept relatively low, abrupt decrease in the compressive strength was observed with the addition of fibers. Increase in the sand/fly ash ratio contributes in the compressive strength up-to a certain limit. Additionally, increase in the W/GP solids ratio caused reduction in the compressive strength. Finally, multi-objective optimization technique revealed that the mix having W/GP solid =0.228848, and Sand/Fly ash =0.120947 would give optimized value.

Treatment of Tilapia Wastewater by Using a Biofilter for Reuse in a Closed Recirculation Fish Culture System

Authors:

DOI NO:

Abstract:

Ammonia treatment in a tilapia pond is considered of great significance, for cleaning and changing water in the pond can cost substantially while ammonia has a high toxicity to aquatic animals. In the experiment of the treatment of tilapia wastewater, a 10 L column reactor and a 10 L baffle reactor were employed. Two biofilter materials included bioball and fiberglass while two types of wastewater were synthetic wastewater and authentic wastewater. From experimenting on synthetic wastewater, it was found that on the same surface area of biofilter media, the baffle reactor could treat ammonia most effectively, yet the water was not reusable for tilapia culture. Therefore, the experiment was further conducted to enhance efficiency in the wastewater treatment for aquaculture. In the same-volume reactors, the surface area of fiberglass could be increased owing to fiberglass having higher void percentage. In contrast, the surface area could not be increased in the case of bioball because of their rigid shape and lower void percentage. Thus fiberglass was used instead in the experiment to enhance the efficiency in wastewater treatment. It was discovered that the biofilter system with the fiberglass used as the biofilter media on the 2.4 m2 could remove the ammonia in the wastewater, specifically decreasing it to 0.2 mg/L, which contributed to the reuse of water for a closed recirculation tilapia culture system.

Abstract:

In textile industry, there is always wastewater which is hard to treat. It is usually caused from fiber softening in finishing process. In this experimental study, electrocoagulation technique was employed with 6 types of softeners with different features and functions. The wastewater was synthesized by dissolving softeners in the treated wastewater from textile factory to manipulate the characteristic of synthesized wastewater so that its matrix became close to real wastewater. In examination of the removal efficiency, COD and TOC were water quality indicators. The experiments revealed that COD and TOC treatment efficiency was not dependent on the softeners’ features and functions, but the efficiency could be indicated by testing the sludge based on SEM and EDX techniques. According to the analysis of the elements in the flocs from electrocoagulation process by EDX, the amount of Al in the flocs was high, which means the synthetic wastewater could be effectively treated. In addition, the analysis from SEM showed morphology of sludge, which could be classified into 3 groups: powder, chunk, and flat sheet. Note that the flat-sheet flocs were well precipitated.

An Improved Technology of Implementation of Foundations in the Rammed Pits

Authors:

DOI NO:

Abstract:

Implementation of foundations in the rammed pits allows to provide the construction of buildings on soft loess and subsidence soils, as well as on clay and loam grounds. Principle of the proposed pit ramming under foundation consists in the fact that a weight of 2.5-15 tons drops from a height of 6-12 m in a same spot. As a result of soil compaction the hollow is formed, in which the reinforcing rebar skeleton is installed and concrete is poured. Foundation in rammed pit, which created in this way, can hold the bearing capacity of up to 10,000 kN. Machineries based on the tractor, the crane-excavator or the ramming machine are used for pit ramming under the foundation. The main strike element is the rammer that falls under its own weight along the guiding rail trunk or the guiding rail road. Using of such machineries and foundation implementation in rammed pit can significantly reduce the volume of excavation work, material consumption and the complexity of implementation.
Pit ramming in the soil with water-saturated layer (aquifer) is associated with some technical difficulties. The softened soil collapses into the pit bottom. Water at the pit bottom contributes to the creation of vacuum, during the removal of rammer, which generates the effect of its suction. It makes the pit ramming without any special measures quite problematic. And at the same time it is necessary to prevent the entry of water into the pit cavity for foundation implementation in the soils with water-saturated layer. A way to successfully cross the water-saturated layer and to implement the foundations in rammed pits is proposed. The developed technology has been repeatedly tested in the constructions of industrial and livestock buildings.

Forecasting the Compressive Strength of Thermal Treated Self-Compacting Concrete during Cast-in-Situ Construction

Authors:

DOI NO:

Abstract:

Thermal treatment (TT) of concrete can significantly accelerate the strength growth during cast-in-situ construction. Forecasting the compressive strength of thermal treated self-compacting concrete (SCC) is one of the pillars of the technical safety of buildings. To this end we carried out a study of strength development issue of SCC during TT. For our study, we used SCC of grade C25. Test samples were cured with TT by infrared radiators for 7, 9, 11, 13, 16 and 24 hours. Then warmed samples were tested for compressive strength after 0.5, 4, 12 and 24 hours of cooling period. Study was carried out on the basis of analyzing, generalizing and evaluations of experimental data. A mathematical model for determining the compressive strength of SCC after one day of curing of SCC with TT is proposed, which allows to forecast the concrete behavior in a real cast-in-situ construction of SCC structures immediately after one day of curing with TT. This paper also presents a technology of TT of structures for cast-in-situ construction with SCC. The proposed technology can be used for mass cast-in-situ construction. Application of this technology allows to reduce the turnover of formwork, the labor costs for construction, and the construction period.

Analysis of Physical-Mechanical Characteristics and Advantages of Bakelite Plywood as Constructional Material

Authors:

DOI NO:

Abstract:

Waterproof plywood as product of the wood reprocessing has the number of advantages for civil engineering, such as: ability to form curved surface; transportability and possibility of quick erection; relatively large size and similar physical-mechanical properties in lengthwise and crosswise direction; resistance against chemical and biological influence. Bakelite plywood is one of the prospective types of waterproof plywood.
The effective introduction of bakelite plywood into civil engineering slows down because of insufficient knowledge of influence of the range of factors on strength and deformability of the bakelite plywood structures. Taking into account the above, the research work is devoted to study physical-mechanical properties of bakelite plywood as orthotropic material. The aim of the research is to obtain the results, which can be used for design of the bakelite plywood structures.
Samples with size 30x30x120 mm, made by bonding the required number of 9-layers plywood sheets with the use of phenol-formaldehyde glue, were used to determine mechanical-physical characteristics of bakelite plywood. The sheets with thickness of 10 mm were used in the research work. Every sample was tested by sixfold loading and unloading with measurement of deformations in the process of loading.
The research results of physical-mechanical properties of bakelite plywood as orthotropic material are shown in the article. They are necessary for practical calculations of tensions in the adhesive joints by methods of elastic theory of anisotropic materials. The possibility of using the obtained research results for practical calculations is shown on the example of the overlapping adhesive joint.

Abstract:

One of the main guarantees of sustainable development of the civilization nowadays is settlement of the energy problem. People will encounter the crisis, connected with the reduction of the modern rate of production due to the depletion of fossil fuels without introduction of energy-saving technologies and renewable energy resources.
The research work is devoted to reduction of the fossil fuels consumption in manufacturing of concrete elements and replacement them by solar energy, which can be used for heat treatment of concrete. Transformation to the renewable energy resources is associated with economic costs, which seem unjustified without taking into account its social and ecological aspects.
The aim of the research work is to develop the methodic of economic assessment of the solar energy use for the manufacturing of concrete elements, taking into account its social and ecological advantages.
The developed methodic includes equitation for determination: of the cost of yearly saving of fuel and energy resources during operation of solar energy equipment; the nonrecurring cost of production and installation of the solar energy equipment; ecologic and social components of the converted economic costs.
The economic assessment shows that yearly replacement of fossil fuels by solar energy is 40-60% in dependence on the geographic area of manufacturing of concrete elements. The yearly economic benefit from replacement of fossil fuels is 60-85 tons of oil equivalent for the plants with manufacturing capacity of 20000 m3, 150-200 tons of oil equivalent for the plants with manufacturing capacity of 50000 m3.

Engineering Trainee Characteristic: How Does This Affect Modern Apprenticeship Training In Malaysia?

Authors:

DOI NO:

Abstract:

Modern apprenticeship training systems require trainees to have the capability to become highly skilled workers. However, most studies only deal with high-skill and knowledgeable terms without deliberating in depth what skills are required in the high-skilled intentions. Thus, this study is conducted to examine the characteristics of the trainers to form the model of modern apprenticeship trainer characteristics to develop highly skilled workers. Modern apprenticeship system should combines elements of mixed trainee ability. Previous study showed that most trainees enter public training institutions due to poor academic results. This creates the view of public vocational training institutions as second-class education. Study using grounded theory method was to identify the factors behinds successful trainees and how they manage their learning process. A total of 32 respondents were interviewed comprising trainees, industry supervisors, and employers. The results showed that there are eight factors that contribute to the success of the trainees in training institutions and also through industrial training before being appointed as an employee. This clearly shows that the success of the apprenticeship training system not only depends on the training system itself but also on the trainees’ characteristics model that are natural or formed by the working environment.

A Goal Programming Approach to Peninsular Of Malaysia Electricity Tariff Structure

Authors:

DOI NO:

Abstract:

Tariff design is the key mechanism used to allocate electricity generation and distribution costs to customers. The designing process can be very complex not only due to the regulatory policies surrounding it but also due to the need of satisfying various parties such as the electricity distributor and the different types of electricity customers. Therefore, it is the aim of this study to formulate an optimum tariff structure for Malaysia that can deal with multiple objective functions. Utilizing secondary data gathered through various energy related sources and a goal programming approach, a new optimum tariff structure has been proposed specifically focused on domestic customers and others in general. The findings show, in the case of domestic users, having only two bands of domestic customers instead of the current practice of five, may have already helped to achieve an optimum tariff structure. The findings also show that for other types of users Malaysian current tariff structure may have yet to achieve its optimum level. While these findings are subjected to few limitations, it is notable that the findings can be used to evaluate the existing tariff structure of Malaysia.

Abstract:

In the process of the study of platform joints of panel buildings, it was established that the most significant contribution to the reliability of the joint is provided by a number of parameters which have specialty randomly. The distribution of these parameters is described by a normal principle that does not have a simple numerical solution. To determine the probability of failure of the connection in the conduct of probabilistic calculations, method of linearization is used, which is based on the method of expanding the initial function in a Taylor series. The work assesses the impact of structural parameters of the horizontal platform joint of panel buildings on the reliability of the connection. The coefficients of ponderability of the investigated parameters are determined in estimating the probability of joint failure. The practical value of the obtained research results is to increase the reliability of the node of interface panel.

Elastic-Plastic Analysis of Space Trusses with Large Displacements

Authors:

DOI NO:

Abstract:

Analysis of spatial bar structures is a labor-intensive and complex task, and it must be carried out taking into account all possible limiting states in various operating conditions of structures. The aim of this paper is to give an insight into elastic-plastic analysis that enables determining the ultimate load of space trusses with large displacements. A direct method is treated in this investigation to gain insight into the computational effort required for the method. The algorithms for the direct methods are obtained by modifying the algorithms for incremental geometrically nonlinear analysis developed by one of the authors to account for yielding and plastic deformation in the bars of the truss. A Java software application has been developed based on the algorithms and the analysis of the space arch truss has been performed. The example demonstrates that direct limit analysis of space trusses with large displacements can be implemented successfully on the Java platform. The computer application is suitable as a test platform for a broad spectrum of investigations into elastic-plastic truss behavior.

Elastoplastic Deformation of Clay Brick Masonry under Biaxial Stresses and Mechanisms of its Performance

Authors:

DOI NO:

Abstract:

Plasticity properties of the masonry appear to be key requirements in order to predict seismic response from masonry construction. On the grounds of the experimental research results, the system of mechanisms of local damage in masonry elements (brick, mortar and contact nodes thereof) is formulated and justified. It is revealed that the state of interaction nodes of basic masonry materials under increasing stress is not irreversible: when the stress state of the node changes, the discrete transition from one state to another becomes possible. The proposed system of mechanisms of local damage and the tools to analyze the state of masonry elements serves grounds for elaboration of a structural model of clay brick masonry as piece-wise homogeneous multimodule composite environment. Based on the results of numerical studies of behavior of the clay brick masonry structural model with the proposed destruction mechanisms as well as on the grounds of the strength criteria system, an accurate prediction of the elastic and plastic deformation phases can be made to determine the plasticity characteristics of the masonry under biaxial stresses.

Abstract:

Vital problem, occurring in the operation process of bearing timber structures, is improvement of their durability in conditions of aggressive environment. Another aspect of this problem is the increase of fire resistance of timber-steel structures. One of the possible design solutions of this problem is given in the research work.
The aim of the research is study of experimental arch with support joints on glued-in steel rods. The arch was developed based on typical timber-steel arch with span length 11.8 m. Geometric shape and sizes of the arch were kept without changes, but steel elements were replaced by timber elements. Design features of the arch and calculation methods, taking into account bearing capacity of the joints on glued-in steel rods, are given in the research work.
The experimental arch showed enough reliability during the test and stiffness during transportation and mounting. The arch loading was carried out in laboratory bench by using hydraulic jacks. The load increased until the arch destruction. Deflection and deformation of glued-in steel rods were measured during the test.
Information about vertical deformation in the arch and stretching tensions along the length of the rods under the load were obtained in the test results. The results show that shear tensions in the joints spread along the bonding length unevenly and they have maximum value on the surface of timber elements. The arch showed perceptivity of practical using in the mild chemical-aggressive conditions and bearing structures with high requirements of fire resistance.

Abstract:

Quick-assembling single-storey houses are one of the possible design solutions if we want to get ready-made houses in short time. It is especially important in locations where new factories and plants, fields of the fossil fuels extraction are developed, various catastrophes occurred and there is a necessity to carry out recovery works. However, the spread of quick-assembling single-storey houses slows down because of design, arrangement and technological complications, which should be settled comprehensively.
The aim of the research work is to provide competiveness of such houses by improving their manufacturing level, which includes design, arrangement and technological solutions, reducing price and time of getting ready-made houses. The manufacturing level is determined by labor input, time and cost parameters.
The research results show that the design solution, improving manufacturing level, is the use of prefabricated flat packets of sandwich-panels, which transform into design position during the assembling process due to transformable joints. The transportation of the flat packets can be carried out if their size allows transporting them by road transport.
The arrangement and technological sustainability of the construction system includes the following stages: selection of separate arrangement and technological conditions of the system; determination of groups of arrangement, technological and economic factors, which influence on sustainability of each condition of the construction system, determination of rational spheres of influence of arrangement and technological factors on cost of the transformable houses.
The developed solutions can reduce cost and time of the assembling process and improve manufacturing level of single-storey houses.

Using Parametric Blocks for Construction of Flat Algebraic Curves in AutoCAD by the Example of Cassini Ovals

Authors:

DOI NO:

Abstract:

Designing surfaces of complex shape is in demand in various industries. Forms of such surfaces are flat curves. However, the variety of these curves remains unclaimed by constructors, architects, designers due to the lack of tools for the rapid construction of these curves in modern graphical systems AutoCAD, Inventor, Revit, KOMPAS, etc. The article suggests a convenient and generally available method for constructing any curves defined by mathematical methods in AutoCAD by creating parametric blocks. For example, the lines obtained by the section of the torus by a plane parallel to the axis are chosen (curves of the fourth order are Cassini’s ovals). In the process of investigation, the features of fourth-order curves are analyzed as a result of the intersection of the torus by planes parallel to the rotation axis of the torus, the shape dependence of the shape of the curves on the ratio of the parameters. We consider the problem of reconstructing the toric metric and forming a model of a spatial object along the contours of the obtained sections by the methods of descriptive geometry and using 3-d modeling. On the basis of the obtained curves, surfaces with generators or guides, which are Cassini ovals, are constructed.

Cancer Relapse Prediction from Microrna Expression Data Using Machine Learning

Authors:

DOI NO:

Abstract:

Cancer is a major deadliest disease globally that involve uncontrolled cell growth and invasion-metastasis events. It accounts for around 13% of all deaths worldwide. Statistical reports have pointed out that the cancer occurrence rate is increasing at an alarming rate in the world. Furthermore, cancer relapse rate is also rising mostly due to late cancer diagnosis. Some cancers can recur at the site of origin or the distant site after years of anti-cancer treatment. Therefore, cancer relapse prediction process is of paramount important so that early specific treatments can be sought. Nevertheless, conventional methods for diagnosing cancer relapse rely on invasive and labor intensive biopsy examinations. Circulating miRNAs have gained great interest in medical field because of their higher sensitivity, specificity and potential for minimally invasive sampling procedures. Furthermore, miRNA expression profiling from body fluid samples using high-throughput approaches is a promising technology that could predict cancer relapse. This paper describes a machine learning based approach called one-dependent estimator to predict cancer relapse from miRNA expression data. The proposed framework will predict whether a particular cancer will relapse within cancer recurrence time frame, which is usually 5 years. To select relevant cancer recurrence associated miRNAs, we employ an entropy-based miRNA marker selection approach. This proposed system has achieved an average accuracy of 92.82% in predicting cancer relapse over three datasets, namely glioblastoma, ovarian cancer, and hepatocellular carcinoma (HCC). The experimental results exhibit the efficacy of the proposed framework.

Influence of Reinforcement of Contour High-Strength Reinforcement without Adhesion to Concrete on the Deflections of Monolithic Beams

Authors:

DOI NO:

Abstract:

Excessively large deflections in the center of the slab are one of the most significant drawbacks that prevent the spread of monolithic flat ceilings during spans of more than 7 m. The influence of the application of contour prestressed reinforcement (in a shell) without adhesion to concrete on the deflections of plates with the aspect ratio a/b=1÷2 is considered in the article. In the work presented, the rope laying path in the slab is represented by a part of the parabola passing through the supports, with a height that is equal to the deflection, and the length of the rope’s diagonal is equal to the distance between the column axes. Knowing the initial equation of the curved axis of the rope, it is possible to calculate the values of the repulsive forces by integrating this parabola equation and obtain a formula for determining the intensity of the repulsion at any point along the length of the rope. With the help of the finite element method, the deflections of a cell of a flat plate were obtained, where the deflection was taken into account in the form of concentrated forces applied at the nodes of the grid of finite elements along the cell contour. According to the results of the study, it is established that the use of a contour high-strength prestressed reinforcement without adhesion to concrete can reduce the deflections of the slab of overlap up to 15% or more. When prestressing only on one side of the cell, it is possible to advise on the installation of prestressed ropes only on the long side of the slab with a ratio of sides a/b=1.3 or more, because the installation on the short side is not advisable.

Abstract:

As the main method of calculating reinforced concrete structures for strength the modern Russian standards have been using the method of limiting equilibrium, which contains some contradictions. In recent years, a discussion has been developing on the transition to the deformation model of the resistance of reinforced concrete used by European code. However, there are a limited number of studies confirming the consistency of the proposed deformation model. We calculated the deformation of a slab on the basis of the Russian standards for theoretical and deformational model. The calculation was carried out by the finite element method using the model of nonlinear deformation of concrete. Then the analysis of the obtained results and their comparison with the results of calculation according to the theoretical provisions of the norms were performed.

Taking into account the 2 sp -hybridization effect for valence electrons in carbon
atoms, we introduce a unitary matrix U as an order parameter and suggest a scalar
chiral model of graphene for the description of carbon nanotubes. We consider both
single-walled and two-walled carbon nanotubes, analyze corresponding solutions to
the model equations and estimate the Young’s modulus. We discuss also the possible
extension of the model in question to describe fullerenes as three-dimensional
hedgehog structures (skyrmions). We find the corresponding Lagrangian density for
the spherirically-symmetric chiral angle. The other extension of the model concerns
spin and magnetic excitations of graphene-based configurations. To this end, the 8-
spinor field should be introduced as a new order parameter (Rybakov, 2015).

Surface Electromagnetic TM Waves along the Boundary between Two Nonlinear Anisotropic Dielectrics

Authors:

DOI NO:

Abstract:

It is shown that the Maxwell’s equations for surface electromagnetic TM
waves, propagating along the plane boundary between two nonlinear dielectrics with
arbitrary diagonal tensor of dielectric permittivity, depending on
2 | | E 
, can be
integrated in quadratures. For the TM plane wave the magnetic intensity has only the
transverse component, but the electric intensity has both transverse and longitudinal
ones. This fact permits one to find the first integral of the Maxwell’s equations and
eliminate the magnetic intensity. The resulting equations for the electric intensity can
be simplified and integrated, if one uses the transverse permittivity as the independent
variable. Finally, we consider the Kerr dielectrics, with the permittivity being a
quadratic function of the electric intensity. In this case the quadratures can be
reduced to the elliptical integrals.

On the Deflection of Light by a Charged Rotating Black Hole

Authors:

DOI NO:

Abstract:

The Kerr-Newman, Schwarzschild, Reissner-Nordström, Kerr and Lense-Thirring metrics have been presented. The deflection of light by Kerr–Newman’s black hole has been evaluated. Expressions for the law of motion and trajectory of light have been obtained. The black hole is assumed to be slowly rotating. The light impact parameter is considered to be much superior to the gravitational radius and classical radius of the black hole. The deflection of light is both due to attraction by the black hole mass and due to repulsion by its charge and specific angular momentum.

Simulation of Quantum Cryptographic System

Authors:

DOI NO:

Abstract:

Quantum key distribution protocols and the questions of their protection were studied. There were estimated mutual influences between legitimate users and for any types of cracker attack. For example, BB84 protocol is shown to be unconditional security protocols using photon polarization between outlying channels. Secret keys share between spatially separated (removed or remote) legitimate users. A simple method of generating a dichotomy signal has also been accomplished. In fact, this method can open the way of probabilistic quantum states. We argue that quantum cryptographic systems can be partially simulate on a classical computer with finite degrees of freedom. Quantum entanglement is a basic tool of communication and processing of the information.

Analysis of Abrikosov Vortices by the Superconductivity Model at the Twin Boundaries

Authors:

DOI NO:

Abstract:

The work is devoted to the study of Abrikosov vortices using the superconductivity model at the twin boundaries (MSC-TB) proposed in the works of V.А. Chizhov. The new model allows a deeper understanding of the mechanism of formation, evolution, and destruction of Abrikosov vortices and associated creep currents. A quantitative comparison of theoretical estimates of MSC-TB with experimental data is carried out. A good correspondence is shown. Methods of fighting with the creep current are sug-gested. Materials are described, including new ones, which, in accordance with the theory of MSC-TB, should have improved properties of superconductivity of the second kind. Perspective directions of further research are formulated.

The Numerical Solution of the Rayleigh-Plisset Equation for Spark Cavitation and Calculation of the Maximum Temperature and Pressure in a Cavity

Authors:

DOI NO:

Abstract:

We study the processes typical for liquids under the influence of powerful impulses of electric current. The maximum temperature and pressure arising in cavitation bubbles at such processes are calculated. To this aim, the main equation of cavitation (Rayleigh – Plisset’s equation) is solved numerically. The maximum amplitudes of fluctuations of temperature and pressure in a cavity are calculated during a collapse. The analysis of the process shows the existence of the extreme value of pressure above which the cavitation is not observed. Before the limiting pressure being achieved, the cavity increases several times, collapses and comes back to the initial radius, oscillating near it. The increasing of the maximum value of the bubble radius yields, therefore, the increasing of the extreme values of temperature and pressure in a bubble at a collapse. It is established that the maximum amplitude of a bubble during spark cavitation can reach values of the order 200. This fact gives the evidence of large local pressure and temperature in the cavity at the time of a collapse. These temperature and pressure have been calculated in this work. The main conclusion is made that in a liquid metal’s phase the intensive cavitation, with local increasing temperature and pressure in a cavity, is possible. Therefore, the process in question can initiate reactions of nuclear fusion in a liquid metal’s phase.

Bi-variational Evolutionary Systems and Approximate Solutions

Authors:

DOI NO:

Abstract:

The use of variational methods for the construction of sufficiently accurate approximate solutions of a given system requires the existence of the correspondent variational principle – a solution of the inverse problem of the calculus of variations. In the frame of the Euler’s functionals there may not exist variational principles. But if we extend the class of functionals then it could allow to get the variational formulations of the given problems. There naturally arises the problem of the constructive determination of the corresponding functionals – in general non-classical Hamiltonian actions – and their applications for the search of approximate solutions of the given boundary value problems. Its solution may not be unique. In particular, there can exists a bi-variational system, i.e. generated by two different Hamiltonian actions. The main aim of the paper is to present a scheme for the construction of indirect variational formulations for given evolutionary problems and to demonstrate the effective use of the non-classical Hamiltonian actions for the construction of approximate solutions with the high accuracy for the given dissipative problem. In the paper there are used notions and methods of nonlinear functional analysis and of modern calculus of variations.

Modeling the Accumulation Kinetics of Anionic Photo-sensitizers in Tumor Cells with Different Trans-membrane Potentials

Authors:

DOI NO:

Abstract:

The accumulation of photo-sensitizer (PS) mainly in tumor cells (TC) is a necessary condition for the effectiveness of photodynamic therapy (PDT). The purpose of this work is the modeling of the accumulation kinetics of anionic PS in TC differing in energy metabolism and trans-membrane potentials (TMP). The kinetic model (KM) including a system of linear differential equations describing the accumulation of PS in some model system based on Nernst theory, is suggested. This system consists of four parallel-sequential compartments separated by permeable membranes with different electric field gradients. These potentials include negative plasma and the mitochondrial TMP as well as energy-dependent positive TMP of the nuclear membranes. The model in question accounts for the phenomenon of reduction of plasma and mitochondrial TMP in TC due to their more rapid division in comparison with normal cells. The KM is constructed for TC of tumor areas sites under hypoxic or oxygen conditions. We conclude that the accumulation kinetics of anionic PS (chlorin E6) in the tumor cells mainly depends on the relationship between the transfer rate constants through their plasma and mitochondrial membranes, these constants being functions of TMP.

Abstract:

The article presents researches of the thinking activity of project schematization. Often, work on the project is done without understanding the problem. The solution appears accidentally and unconsciously. The quality of the result depends on the algorithm of conscious plans. Techniques of thought schematization allow us to more consciously approach design. This technique has been tested in design practice by three project teams. We investigated the technique of schematization of thought on five educational projects. The research was carried out in three project groups using the example of training projects. The results of the research showed the best effectiveness in the group, which conducted a reflexive analysis and worked with the technique of the schematization described in the article. The results of the group that worked on this technique were better than the rest. One of the basic concepts is reflexive analysis, which allows both identifying and mastering the actualization of the design process. The group that made the reflexive analysis also showed better results. This is part of the methodology of schematization, which is described in the article. The algorithm of thought activity and the actualization of the techniques of schematization in project thinking are disclosed.

The efficient design of valves for the water supply system requires knowledge of the parameters and regularity of change in the hydraulic characteristics of the locking pair. The article contains the results of a study of regularity of change in the hydraulic characteristics of the locking element in the form of a “curved drop” for plumbing fittings.
The numerical values and the patterns of change in the hydraulic characteristics of liquid outflow through the hole in the form of a “curved drop”, made in a thin wall defined. The patterns of change in water discharge identified, and the comparison of characteristics for different bore shape.
The ability to adjustment the flow of water depends on the shape of through hole. The values and regularity of change in the hydraulic characteristics of the locking element in the form of a ” curved drop” for water reinforcement obtained on the basis of theoretical and experimental studies. The results of the study are of interest in the theoretical and practical aspects for the design and manufacture of valves for water supply.
The results of theoretical and experimental studies show that the form of “a curved drop” for plumbing fittings allows to have a linear change in water consumption depending on the opening tap. The coefficients allow us to design the plumbing fittings valve type with a high regulating capacity.
The use of the locking element with a hole in the shape of a “curved drop” allows to reduce the loss of tap water of drinking quality. Water savings for the house for three persons is 12-15% compared to valves of other types.
The study is in the continuation.

Geometrical Aspects of the Equilibrium Statistical Thermodynamics

Authors:

DOI NO:

Abstract:

The geometrical approach due to Gibbs in the equilibrium phenomenological, or Clausius, thermodynamics (CTD) is generalized for the statistical case (STD), which is naturally stipulated by the stochastic nature of the thermal contact between the TD-object and the external surrounding (thermostat). To this end the probabilistic measure p is introduced into the affine space of finite-dimensional space of basic TD-variables, which is parametrized by means of the intensive variables of the thermostat. For the case of strongly additive extensive TD-variables the measure p possess the exponential, or canonical Gibbs form. The ordinary Clausius TD-variables are then Gibbs TD-variables averaged with the measure p and of primary interest are the relevant spontaneous fluctuations; in particular, they determine the accuracy of Zeroth Law of TD fulfillment.

This paper looked into the effectiveness of refined basalt in the Nigerian civil and structural engineering world. Current technology has been in search in the development of new type of composites which are made to measure the required conditions. A general problem of new types of structures made from high performance materials is their behavior in certain specific conditions and situations. Temperature in Nigeria keeps increasing every season. The specific gravity, tensile strength, elastic modulus, rupture strain and melting point of basalt materials are the properties in consideration for the use of the basalt material listed below in use. This increase in temperature has been an issue of concern to scientists and engineers. This concern brought about the use of basalt made materials in the construction of utilities and buildings. Basalt which is a natural resource with the ability to contain high and low temperature was looked into in this paper. The three basalt formations discussed in this paper out of other formations found in Nigeria are: Bachit Basalt Rock Formation, Kahwang Rock Formation and Ikom Columnar Basalt. Basalt fiber wool, rebar, sandwich panels, roving and roofing sheet are the basalt materials discussed in this paper for proper utilization in the Nigerian structural construction.

Abstract:

This work explores the ways that brought the development of Latin American architecture to the highest extent of morphologic complexity. Understanding the evolution of forms and fusion of different traditions we can research the possibility of the progress of classical forms and ways of further possible development of the architecture and culture overall. An objective of this work is to prove that the formation of the Latin American Baroque was not an accidental combination of influences but a conscious elaboration of a universal architectural concept enabling convergence of East and West and confluence of the most various cultures in one unity. The main emphasis is put on the correspondence between the processes happening in Latin American and in Russia featuring the Eurasianist principles of cultural formation in both cases. The similar circumstances that induced the generation of progressive architecture are investigated in order to figure out the universal formation principles applicable to any kind of architectural innovation.

Abstract:

Wastewater from water softening stations contains a large amount of calcium and magnesium salts. The results of studies aimed at using these waters as natural solutions of calcium and magnesium ions in the processes of reagent purification of other categories of wastewater are presented. The conditions for the formation of sparingly soluble calcium and magnesium compounds during their alkali treatment using potentiometric titration were studied. According to the results of potentiometric titration of solutions of magnesium and calcium salts with alkali, the ranges of the active reaction of the medium are established, corresponding to the formation of pre-cipitates in the form of hydroxides for magnesium and calcium. The potentiometric titration curves have sufficient selectivity for the quantitative evaluation of the com-pounds formed with acceptable accuracy. It is established that the interaction of pollu-tants of real sewage with freshly formed precipitation of calcium and magnesium hy-droxides occurs according to the adsorption mechanism. Data on the sorption proper-ties of calcium and magnesium hydroxide precipitation in relation to pollutants of textile enterprises are presented. The greatest efficiency of water purification is achieved by solid dispersed impurities absorbed by hydroxides at the time of structure formation and by dyes. The extraction of hydrocarbons, such as petroleum products and surfactants, does not exceed 40%.

EXAMINATION OF THERMAL INSULATION OF EXTERNAL WALLS USING THERMAL IMAGER

Authors:

DOI NO:

Abstract:

One of the most important ways to increase the thermal and energy efficiency of buildings is to improve their thermal insulation. Thermal insulation of external walls is relevant not only for climatic conditions with a cold period of the year, but also for climatic regions with increased heat input into the premises. At present, the insulation of external walls with placing of cladding on some distance from the wall (ventilated facades) is increasingly used to improve the thermal efficiency of the enclosing structures of buildings intended for various purposes. Using of thermal insulation of external walls with placing of cladding on some distance from the wall allows to get significant reduction of energy costs not only for heating buildings in winter, but also for their cooling during the summer period of the year. It is most expedient to check the effectiveness of thermal insulation with the use of thermal imaging equipment. This allows us to obtain actual data on the thermal radiation of the enclosing structures. As part of thermal imaging survey of the building’s facade is determined the heat-and-energy efficiency of the made insulation of the enclosing structures was determined. Also areas with increased thermal radiation due to the poor quality of the heat-insulation works were identified. As a result of the thermal imaging survey, the assessment of the thermal energy efficiency of the insulation with placing of cladding on some distance from the wall was made, and areas with increased thermal radiation were identified.

Study of Reinforced Concrete Beams with Indirect Reinforcement of Compressed Zone in the Form of Cross Welded Mesh

Authors:

DOI NO:

Abstract:

One of the design solutions, saving materials and increasing strength and deformation characteristics of concrete, is the use of indirect reinforcement. The volume of research devoted this problem for bending elements in comparison with compressed elements, is rather low. The aim of the research work is to analyze the influence of the indirect reinforcement on strength and deformation characteristics of the reinforced concrete beams.
The test results of three batches of the beams with indirect reinforcement of compressed area in form of cross-welding mesh are given in the research work. Each batch consisted of the sample without mesh and two samples with various coefficients of the indirect reinforcement of compressed area. The batches were different from each other by the area of longitudinal reinforcement.
The pattern change from brittle to plastic destruction of the samples was identified in the results of research. In this case, the limit deformability increases considerably with saving the high residual bearing capacity.
We noticed that the influence of the indirect reinforcement on the beams work depends on not only coefficient of indirect reinforcement but also the area of longitudinal reinforcement. We explain it by growth of large deformation in concrete of the compressed area in the limit condition and, therefore, more effective inclusion of the indirect reinforcement. The bending reduction is 7.2-14.4% for the samples with mesh, the increase of the bending moment, satisfying the beginning of the concrete destruction of the compressed area, is 11-33%.

Static Two-Beam Surface Plasmon Interferometer of the Terahertz Range

Authors:

DOI NO:

Abstract:

A new scheme of static surface plasmon-polaritons (SPPs) interferometer of the terahertz (THz) range is described. The interference pattern is formed due to interaction of two converging SPP beams that have run different distances. The original SPP beam is splitted and reflected by a flat beam splitter and a mirror disposed of the waveguiding surface and normally to it. By varying the distance spacing the splitter and the coupling element one can change the pattern period. Execution of the pattern enables one to determine both the real and imaginary part of the SPPs refractive index, which is uniquely related to the dielectric constant of the surface and the optical characteristics of its transition layer. The operating time of the interferometer is determined by the photodetector time constant, which is extremely important for studying fast processes on a conducting surface. The interferometer can work with broadband THz radiation sources (such as synchrotrons or pulsed lasers) as well.

The thermal data of onset temperature, peak temperature and enthalpy of reaction of hydrogen peroxide at 35% w/w was tested by differential scanning calorimetry. The increasing of heating rate in the range of 2-8 °C/min increases the onset temperature from 76.9-84.0 °C, respectively. The activation energy of hydrogen peroxide was 57.6kJ/mol. The adiabatic decomposition temperature rise and time-to-maximum rate were 231.7 K and 32.3 sec, respectively. The thermal hazard potentials were estimated by the critical half thickness, the critical temperature and the time-to-thermal-runaway. The result confirmed that hydrogen peroxide is highly oxidizing hazardous material. Thus using in laboratory and industry must be act carefully.

Healthy Routes To School (HRTS) For Overweight and Obesity Children

Authors:

DOI NO:

Abstract:

The trend of overweight and obesity cases in developing countries in recent years have been particularly alarming as the cases are consistently on the rise. Improving the economy rate has resulted to the increasing number of overweight and obesity cases among adults and children in a family. Overweight and obesity have commonly been known to associate with eating habits and this belief is assimilated into the people for many years. However, recent studies suggest that the factors to the issue are extended to the convenience and comfort that modern technologies have provided which affects our lifestyle due to passive mobility. Therefore, it is important that the awareness of practicing healthy lifestyle is incorporated in young children. Although there are efforts towards this campaign such as organizing physical activities in school as a part of the curriculum, it is insufficient to burn enough calories. Thus, Healthy Routes to School (HTRS) concept is introduced as a strategy to cope with this issue by encouraging childhood walking so its positive effects on health can be benefited. The use of Geographic Information System (GIS) in this research is to monitor the distance and BMI classification, and to calculate the appropriate time taken for each mobility mode. The results were classified into four categories which are walking, public transport, parent vehicle, and cycling. Children that use parent vehicle and public transport contributed to 82.35% of overweight and obesity class while 17.65% were normal and underweight. In order to promote the HRTS concept, the distance and time taken were calculated to determine the most suitable and comfortable distance for walking and cycling to school.

Urban Built-Up Effects to Land Surface Temperature

Authors:

DOI NO:

Abstract:

Shah Alam is one of the regions which has a dense population and high level of urbanization in Malaysia. The study assumed high urbanization leads to the increase of temperature. The aim is to study the trend and relationship between Land Surface Temperature (LST) with built-up areas and Normalized Difference Vegetation Index (NDVI) in three different years (1997, 2007, 2017) in Shah Alam, Selangor. This study used Geographical Information System (GIS) and Remote Sensing software to process satellite imagery data (Landsat 5 TM, 7 ETM+, 8 OLI). Built-up area was processed using Principal Component Analysis (PCA) from Landsat 8 (OLI) while the land use land cover was processed using Supervised Classification method. The results were analyzed using linear regression analysis in the Statistical Package of the Social Science (SPSS) to describe the relationship of the LST with built-up area and NDVI. The highest LST distribution of 35.717ºC is recorded in 2017. This indicates that built-up area gives more impact to the increase of LST in Shah Alam despite NDVI having the highest correlation relationship as shown by the values of R² which are 0.557, 0.533, and 0.585 for year 1997, 2007, and 2017 respectively. This paper focused on the changes of land use land cover for built-up area (i.e. residential and industrial area) which have increased from year 1997 to 2017. In year 1997, the percentage of built-up area is 36.69% and it has increased to 44.36% in year 2017. The study can conclude that urban built-up is one of the major factors in the increasing LST.

Two Level Security Approaches System Architecture for Secure XML Database Centric Web Services against XpathInjections

Authors:

DOI NO:

Abstract:

Web services are deployed using eXtensible Markup Language (XML), which is an independent language for easy transportation and storage. As an important transportation for data, Web services has become increasingly vulnerable to malicious attacks that could affect essential properties of information systems such as confidentiality, integrity, or availability. Like any other application that allows outside user submission data, Web services can be susceptible to code injection attacks, specifically XPath (XML Path Language) injection attacks. This kind of attack can cause serious damage to the database at the backend of Web services as well as the data within it. To cope with this attack, it is necessary to develop effective and efficient secure mechanism from various angles, outsider and insider. This paper addresses both outsider and insider threats with respect to XPath injections in providing secure mechanism for XML database-centric Web services. We propose the two level security approaches for the ultimate solution within XML database-centric Web services. The first approach focuses on preventing malicious XPath input within Web services application. In order to address issues of XPath injections, we propose a model-based validation (XIPS) for XPath injection attack prevention in Web service applications. The second approach focuses on preventing insider threat within XML database.

Mortality Trends of Male Elderly in Malaysia: Comparison between Lee-Carter model and Heligman-Pollard model

Authors:

DOI NO:

Abstract:

Human life expectancies have shown remarkable improvement and this leads to significant reductions in mortality rates across all age groups, genders and countries. In Malaysia, mortality rates have been declined significantly due to the increases of life expectancies of an individual. Thus the proportion of the elderly in Malaysia is increasing. This study examines the mortality trends for male elderly of age group 60-64, 65-69, 70-74 and 75-79. The mortality trends analysis is done by discussing the pattern of mortality rate for the past 35 years period and 10 upcoming years resulted from Lee-Carter Model and Heligman-Pollard Model. Since these models involves nonlinear equations that are explicitly difficult to solve, the Matrix Laboratory (MATLAB) software will be used to estimate the parameters of the models. Autoregressive Integrated Moving Average (ARIMA) procedure is applied to acquire the forecasted parameters for both models as the forecasted mortality rates are obtained by using all the values of forecasted parameters. It was found that the declining trend of mortality in each age group although there is a fluctuation along the past 35 years. However, the estimated mortality rates for both mortality models move along with the actual rate.

The Basics of Special Relativity are the Same: It is A Deliberate Attempt for Conceptual Modifications Only. Space – Time is A Curvature (Complete Closed Loop) for Fermions only And Space – Time is A Curvature (Semi – Elliptical) for Bosons.

Authors:

DOI NO:

Abstract:

A defining year in physics was 1905 when great Einstein first postulated a great theory in physics: the special theory of relativity. Very few understood the theory that time and even fewer believed in this theory. Keeping all the basics of that theory intact, it is just a deliberate attempt to introduce some conceptual modifications in the special theory of relativity. This paper also focuses on space – time as a curvature (Complete Closed Loop) for fermions and space – time is a curvature (Semi – Elliptical) for bosons. The assumptions are made that mass and velocity of a particle or antiparticle cannot go negative. A revision on the mass – energy equivalence equation is proposed in this paper and theoretical relationships of space – time for fermions and bosons are proposed with some conceptual modifications in the special theory of relativity in the light of particle and antiparticle pair production and annihilation. In this paper, conceptual modifications are arranged in such a way to justify conclusion.

Elasto-damage Modeling of Concrete Subjected to Proportionate and Non-proportionate Multiaxial State of Stress

Authors:

DOI NO:

Abstract:

This study focuses on the improvement of predictive capabilities of elasto-damage model, initially proposed by Khan et al., for concrete subjected to multiaxial state of stress. The critical energy release rate 𝑅𝑐, which was initially assumed constant, is defined as a function of 𝑓𝑐′, and 𝐸𝑜 in the present study. Parameters 𝛼,𝛽 and 𝛾 used in effective compliance matrix, are redefined for the proposed form of 𝑅𝑐 by regressing against available experimental data to obtain better estimates. The computer code for implementing the model is modified such that it is able to predict the response of concrete under both proportionate and non-proportionate loadings. The predictive capability of model to simulate stress-strain response of concrete subjected to multiaxial stresses and confining pressures is shown to have improved. The model is able to predict essential phenomenological behavior of concrete which relate well with the experimental results.

Abstract:

Building information modelling (BIM)Building information modelling (BIM) is a new way of approaching the design and documentation of building projects. The objective of BIM is not only to model and manage graphics, but also information – information that allows the automatic generation of drawings and reports, design analysis, schedule simulation, facilities management, and more – ultimately enabling the building team to make better-informed decisions. This thesis documents the modelling of a real life structure (Qayyum Stadium) as well as implies interoperability checks between BIM tool and SAP2000 analysis software.
The Pavilion of Qayyum Stadium is located in Saddar, Peshawar. The data like plans of the structure was acquired. The structure was modeled in BIM tool, Tekla Structures v20. The structure was then exported to SAP2000 for analysis. In SAP2000 Gap analysis was performed to determine the structural elements which were not translated by SAP2000 like curved slab, column beam joints. The component catalog option is an important asset in BIM tool, Tekla Structure, making it easy to counter various flaws during the reinforcement placing. The reinforcement detailing of the structure are done using Tekla Structures, Drawings are generated, quantity take offs are done, Clash Detection tool was applied, which is one of the important tool in Tekla Structure (BIM).
Nowadays the Architecture, Engineering, Construction (AEC) sector has the intentions to deliver a product through formal procedures, which will not depend on design process. With the development in technology, many sectors(production and business) other than construction industry of production and business (outside of construction) are being modified and refurnished, due to which the construction industry lays behind. Presently construction process is same as it previously hundred years before, from the set of drawings. Mostly these drawings have errors and limitations which ultimately results in delays, increase in project cost and delay in project completion. These limitations and errors can be improved through Building Information Modelling tool.

Abstract:

In multimedia community, cross modal similarity search based hashing received extensive attention because of the effectiveness and efficiency of query. This research work contributes large scale dataset for weakly managed cross-media recovery, named Twitter100k. Current datasets namely Wikipedia, NUS Wide and Flickr30k, have two main restrictions. First, these datasets are deficient in content diversity, i.e., only some pre-characterized classes are secured. Second, texts in these datasets are written informal dialect, that leads to irregularity with practical applications. To overcome these disadvantages, the proposed method used Twitter100k dataset because of two major points, first, it has 100,000 content-image pairs that are randomly crawled from Twitter and it has no importance in the image classifications. Second, text in Twitter100k is written in informal language by the clients. Since strongly supervised strategies use the class labels that might be missing in practice, this paper mainly concentrates on weakly managed learning for cross-media recovery, in which only text-image sets misused during training. This paper proposed a Random Multimodal Deep Learning (RMDL) based Recurrent Neural Network (RNN) for cross-media retrieval. The variety of input data such as video, text, images etc. are used for cross-media recovery which can be accept by proposed RMDL in weakly dataset. In RMDL, the various input data can be classified by using RNN architecture. to improve the accuracy and robustness of the proposed method, RMDL uses the specific RNN structure i.e. Long Short-Term Memory (LSTM). In the experimental analysis, the results demonstrated that the proposed RMDL-based strategy achieved 78% of Cumulative Match Characteristic (CMC) compared to other datasets.

Abstract:

This study investigates the dynamic response | E*|, rutting susceptibility and fatigue resistance of the virgin HMA and HMA blended with RAP and further RAP with hydrated lime mixtures. Optimum binder contents were obtained using Marshal Mix design method and the samples for performance testing were prepared. The Superpave Gyratory Compactor (SGC) was used. The samples were then cored and trimmed to the specified dimensions. Using Asphalt mixture performance tester (AMPT), test was conducted at four different temperatures (4. 4, 21. 1, 37. 7 and 54. 4) and six different frequencies (0.1, 0.5,1,5,10 and 25). And flow tests were conducted at only one temperature of 54.4 C. The viscous properties of the mixture and the dynamic response indicators were brought into account to obtain the fatigue parameters to evaluate the fatigue resistance and from flow tests the rutting susceptibility was evaluated and the results showed that RAP and lime has weak resistance to fatigue but are less susceptible to permanent deformation. Master curves for all the mixtures were developed. HMA blended with RAP are very cost effective and environmentally friendly. The flow number results revealed that the virgin HMA accumulated more strains at less loading cycles as compared to the other mixes.

Abstract:

Soil pH is one of the major factors to be considered before doing any cultivation. Farmers always tested their soil pH either in soil pH laboratory, soil pH color chart or sometimes with the help of an expert. But these methods need time, labor and expertness. In this paper, a digital Smartphone image-based method is presented which predicts the soil pH in a simple and accurate way. Soil images are captured with the help of Redmi 3S prime Smartphone and store all the images as soil dataset. Soil images are processed through the different steps of digital image processing including soil image enhancement, soil image segmentation, and soil image feature extraction. During the feature extraction, Hue, Saturation and Value of the soil image are calculated and store Saturation and Hue plus Saturation as an index for the feature vector of the soil images. Prediction of soil pH is done with the help of Linear Regression, Artificial Neural Network, and KNN Regression. The coefficient of the linear regression is 0.859 for the Saturation feature of the soil image. Again, the coefficient of linear regression is 0.823 for Hue plus Saturation. The regression coefficient for ANN is 0.94064 with Levenberg-Marquardt algorithm and 0.92932 with Scaled Conjugate Gradient Backpropagation Algorithm. The regression coefficient of KNN is 0.89326 for K=5 with an RMSE value 0.1311. It is found that ANN always gives a better result as compare to another one.

Gasification of Solid Waste

Authors:

Abstract:

With an increasing demand for electrical energy, it is certain that the production will also increase, especially in rapid developing countries like Pakistan. Rapid industrialization is carving for more electrical energy, investment and suitable space for its infrastructure. But this development has to be sustainable keeping in mind the increasing global temperature due to pollution. Pakistan is the six largest populations in the world and hence produces a lot of waste daily. As of now, most of the waste goes to the landfills and gets burnt there or decomposed, either way releasing greenhouse gases in the process and degrading the environment. The municipal waste management is a challenging process in developing countries because of non-availability of proper infrastructure. There are some methods to manage this waste, such as scientific landfills, Incineration, Biomethanation, Gasification, Pyrolysis and Plasma Arc Gasification. By gasification the solid waste is converted into synthesis gas which can be used for chemical industries, power generation, transportation and industrial heating etc. This process shrinks the solid waste to slag or ash which can either be used to manufacture eco bricks or can be disposed of on landfill. Thus saving a lot of place from land filling and if used for power generation it does not release any considerable harmful gases into the environment making it a sustainable process and partially renewable source of energy. This project will estimate the cost and procedure to setup gasification plant. In the study, the generation, composition, treatment and energy potential of solid waste have been studied. The technologies for waste-to-energy conversion have also been studied and the feasibility comparison of two leading technologies has been done.

employing (modified) Adaptive Kalman Filter (AKF). AKF allows optimization over
lesser number of parameters as the variance ( 2
v  ) of the noise in the volatility state
equation is determined by the AKF. The adaptive method, instead of a constant 2

allows it to be time varying. Before applying the methodology on market data, the
proposed method is characterized here by synthetic data through simulation
investigations. Numerical experiments show that the performance of SVM based QMLKF

Identity-Based Directed Signature Scheme without Bilinear Pairings

Authors:

DOI NO:

Abstract:

P. Vasudeva ReddyThe most important contribution of modern cryptography is the invention of digital signatures. Digital signature schemes have been extended to meet the specific requirements for real world applications. A directed signature scheme is a kind of signature scheme intended to protect the privacy of the signature verifier. In directed signature schemes, a signer signs the document/message for a designated verifier so that only the designated verifier can verify the validity of the signature and others cannot do. Thus the restriction of verification is controlled by the signer. Such directed signature schemes are applicable in many situations where the signed message is sensitive to the receiver such as signature on medical records, tax information etc. However all the existing directed signature schemes in ID based setting uses bilinear pairings over elliptic curves. Due to the heavy computational cost of pairing operations, these existing ID based directed signature schemes are not much efficient in practice. In order to improve the efficiency, in this paper, we present an efficient Identity-based directed signature scheme without pairings. The proposed scheme is proven secure under the assumption of elliptic curve discrete logarithm problem is hard. In addition, this scheme improves the efficiency than the existing directed signature schemes in terms of computational cost.

Optimal Image Compression based on Hybrid Bat Algorithm and Pattern Search

Authors:

DOI NO:

Abstract:

In this paper, multilevel image thresholding for image compression is proposed for the first time using Shannon entropy and Fuzzy entropy, which are maximized by the nature-inspired hybrid Bat algorithm and Pattern Search (hBA-PS).The ordinary thresholding method gives high computational complexity, but while extending for multilevel image thresholding, the optimization techniques are needed in order to reduce the computational time. Particle Swarm Optimization (PSO) and FA (Firefly Algorithm) undergo instability when the particle velocity is maximum. It is evident that Bat Algorithm (BA) is good in exploitation whereas Pattern Search (PS) is good in exploration. We hybridized the BA and PS based on their strengths and weaknesses. The proposed technique (hBA-PS) is compared with Differential Evolution (DE), PSO and BA for which the experimental results are compared in terms of Standard deviation, Computational time, Peak Signal to Noise Ratio (PSNR), Weighted PSNR and Reconstructed image quality. The performance of the proposed algorithm is found to be better with Fuzzy entropy compared to Shannon.

An IOT based Novel approach to predict Air Quality Index (AQI) using Optimized Bayesian Networks

Authors:

DOI NO:

Abstract:

As the size of the air quality data increases, it is difficult toforecastthe air quality metrics due to the non-stationary and randomization form of data distribution. Air quality prediction refers to the problem of finding the air quality by using statistical inference measures. However, traditional air prediction models are based on static fixed parameters for quality prediction. Also, it is difficult to classify and predict the air quality index for both rural and urban areas due to change in data drift and distribution. PM2.5 is one of the major factor to predict the air quality index (AQI) and its severity level. Due to high noisy and outliers in the PM2.5 data, it is difficult to classify and predict the air quality by using the traditional quality prediction models. In order to overcome these issues, an optimized Bayesian networks based probabilistic inference model is designed and implemented on the air quality data. An IOT enabled Air pollution monitoring system includes a DSM501A Dust sensor which detects PM2.5, PM1.0, MQ series sensor interfaced to a Node MCU equipped with ESP32 WLAN adaptor to send the sensor reading to Thing Speak cloud. In the proposed model, the data is initially gathered from the ICAO records of Safdarjung weather station and pre-processed.An improved discrete and continuous parameter estimation and bayes score optimization are implemented on the air quality prediction process. Experimental results show that the present optimized Bayesian network classify and predicts the air quality data with high less computational error rate and high accuracy. Further the proposed optimized model is applied on the real data which is gathered using IOT enabled gas sensors and the model is giving best results in predicting the air quality Index.

Abstract:

This research aims to discover the optimal anisotropic wet etching condition in order to reduce hillocks that occur on the etched surface or reduce roughness and increase etch rate for 45 degree of wall angle (micro-mirror) of a silicon substrate by adopting a design of experiment (DOE) technique and the factorial 2k. Three potential factors which are an ultrasonic mode, a speed motor and a sample orientation, are employed in the factorial design. Analysis of variance (ANOVA) at a p-value significance level of 0.05 is used to assess the significance of the factors on an etch rate and a surface roughness (Ra). The silicon substrates were etched in 20 wt. % sodium hydroxide (NaOH) with Isopropyl alcohol (IPA) at 60 ͦC of solution temperature. An experiment with 24 runs, eight conditions and three replications for each condition, was performed and it was found that the ultrasonic mode was a significant factor which affected the etch rate. An ultrasonic mode and a speed motor were significant factors influencing the surface roughness (Ra). The optimal conditions of 45 degrees of wall angle of a silicon substrate, which were the maximum etch rate and the minimum roughness, were investigated by using a desirability optimization technique in sense of a soft mode of ultrasonic, a speed motor of 5 rpm and a vertical orientation with a desirability value of 0.7619.

DOI NO:

Abstract:

With increase in use of fibres for strengthening of Reinforced Concrete (RC) beams, Textile Reinforced Mortar (TRM) is becoming a popular choice among the researchers and scientists. While Carbon, glass and PBO fibers have shown encouraging results for structural strengthening, use of basalt fibres have not been much explored for strengthening other than masonry. Limited small-scale data exists for the use of basalt fibres in TRM strengthening but data for full scale beams is scarce. This paper presents an experimental study of six full scale RC beams tested with a varying shear span to depth (a/d) ratio 3 through 6, where three beams served as control beams for various a/d ratios while the remaining three beams were strengthened with TRM using basalt fibres. TRM was provided at the tension face of the beams for strengthening in flexure along with U-shaped wraps. Results showed that TRM using basalt fibres is effective in improving the performance of RC beams in terms of serviceability, crack and deflection control, load carrying capacity, initial and post cracking stiffness, and ductility.

Abstract:

The small perturbation method is widely used in attempting to model non-linear systems. Many systems nowadays in different domains exist as adaptive-parameter type models, where the control effort is not applied as in input to the system (as is usually the case) but as a change to the parameter within the system itself. This paper attempts to analyze a non-linear adaptive-parameter type system, using the small perturbation method for linearization. The Ward-Leonard DC Motor with thyristor field control is used as a “test bench” here as it is suited for being an adaptive parameter system. The results and inferences from this study can easily be generalized to a wide variety of systems in applied mathematics, general control systems, power systems, robotics etc.

Authors:

DOI NO:

Abstract:

This paper aims to model and forecasting on GDP data of Bangladesh for the period of 1960 to 2017. To test the stationarity of the series graphical method, correlogram and unit root test were used. The time series plot of GDP shows a non-stationary pattern and overall this is like exponential curvature shape. Hence the data have been differenced twice to convert the data from non-stationary to stationary. From the autocorrelation function (ACF) and partial autocorrelation function (PACF) we obtain the order of the time series model. The chosen model was autoregressive integrated moving average ARIMA (1, 2, 1). The model has been fitted on data to estimate the parameters of autoregressive and moving average components of ARIMA (1, 2, 1) model. For residual diagnostics, correlogram, Q-statistic, histogram, and normality test were used. Also, Chow test was used for stability testing. Using model selection criterion and checking model adequacy, wesee that the model is suitable in shape. It is found that the forecast values of GDP in Bangladesh are steadily improving over the next thirteen years.

Abstract:

Because of the prolong use of the system, the performance (Output parameters of the system) can change and output of the system may start deteriorating from the desired value. If the performance of a system, based on control theory is not up to the expectations as per the desired specification, then some changes in the system are required to obtain the desired performance. The control system can be represented with a set of mathematical equations called system model which are used to answer questions via analysis and simulation. A model is a precise representation of a system dynamics which are the arrangement of physical elements and that physical elements are analyzed to make governing equations. Cardiovascular muscle senses the force generated due to the contraction and expansion of muscle wall .This can be well understood by the analytical approach of the transfer function generated by using a mechanical model of force displacement analogy. The efficiency of the work also lies in the measure of the movement of cardiovascular factors in the system. The mass of heart muscle varies with different age groups both for male and female. This work is based on the glimpses of changing transfer function with different age groups due to the variation of mass of heart muscle. Viscous drag has also been calculated considering different values of damping coefficient for a particular value of mass. For attending the optimality in the performance of the system one designed controller is used along with the derived transfer function in cascade arrangement. To get more stability of the system, damping coefficient is chosen for the system model considering less settling time and steady state error. The open loop transfer function in the forward path is simply the product of derived transfer function and designed transfer function of controller. The design emphasizes on the optimality in operation of the control process which has been determined by the performance index (PI) of the total process using integral square method.

Abstract:

One of the most frequently used mechanism to estimate the basin’s hydrological response due to precipitation is Hydrological modeling. In the paper to pretend the rainfall-runoff processing Upper Indus Basin, Pakistan the HEC-HMS model is used. The development of most of hydrological methodologies is done before 1990. But the advancement in GIS technologies and the management of spatial data has assisted repetitious processing tasks for high resolution datasets improving efficiency and spatial variations. Although large amount of data are often required but the preprocessors in GIS helps hydrological modeling through the semi-automated spatial analysis. We used HEC-HMS for hydrological modeling of Upper Indus Basin. To estimate the watershed discharge over time, the HEC-HMS routes a runoff hydrograph through the stream network. It produces the event based storm hydrograph which can be used in urban drainage design, water management, reservoir design, land use impact studies, flood forecasting and floodplain mapping To cover seven years (2005-2011) data Rainfall-runoff simulation is done using random rainstorm measures of these years.

To Negate The Power Losses In Grid System By Selecting Case Study Of Malakand Divison

Authors:

DOI NO:

Abstract:

Electricity frame has constantly changed over the past decades but there has
not been quite improvement on increasing the production capability. Keeping in view
of the increased movement of population from the rural to urban and ever increasing
load of the industrial and agricultural areas the need for electrical power has sky
rocketed. There is not only problem with the production side but also with the
transmission to the consumer end which makes the problem even more serious and
needs to be addressed vigilantly. The load demand of Chakdara and other grid
station was calculated as 550 MV. The available source for Mardan to Chakdara
could cater load = 270MW load shered and Dargai, Golan gol and Bahrain
Powerhouse equal to 60MW. Load demand to be covered =550-(270+50) =
220MVA. By energizing 220 kV grid station Chakdara the load shered = 240 MW,
load shedding vanished. This research paper brings us to this conclusion that the
system is facing issues like identification of problems, proper management, and
inability of the government to take appropriate action, lack of investing parties and
also highlights and point out the areas that need improvement.

A comparison of Seismic Behavior of Reinforced Concrete Special Moment Resisting Beam-Column Joints vs. Weak Beam Column Joints Using Seismostruct

Authors:

DOI NO:

Abstract:

This paper focusses on a numerical model of a Reinforced Concrete Special
Moment Resisting frame beam-column joint. The software chosen for this purpose is
Seismostruct. The experimental models chosen for this purpose; referred to as
Model-1 (Code Compliant), and Model-2 (Non-code complaint), are two-story twobay
frames based on experimental model scaled at 1:3, and tested in University of
Engineering and Technology Peshawar. Link elements that follow a distinct predefined
constitutive law based on Kim (2012) and Takeda (1970) have been
introduced at beam-column joint interface to simulate the failure mechanism in joint
panel. Roof displacements, base shear and local damage mechanism of the numerical
analysis are compared with the experimental results for the verification of the
calibrated numerical models. The results showed close similarity of experimental
data with numerical results with a percentage error of less than 5 percent and
showed a very close resemblance of local damage mechanism. The numerical models
obtained is further used to perform the seismic evaluation of code compliant and
code deficient models and results like drift profile and inter-story drift ratio are
calculated. Furthermore the response of both models against DBE and MCE is also
determined and results shows that beam-column joints in code compliant as well as
code deficient models behave in an inelastic manner and hence considering a beamcolumn
joint element as a rigid panel in MCE analysis is not a valid assumption. In
addition to shear cracking, bar slip mechanism was also generated in code deficient
model which caused in an increased story drift, which can be prevented by adequate
design of beam-column joint assemblage providing confinement for the concrete strut
mechanism and proper bond anchorage to avoid bar slip mechanism.

Abstract:

The control system consisting different components mainly regulates,
manages as well as senses the behavior of another system and gives the desired
output. The properly tuned controllers are used widely in different industrial
applications. This paper concentrates on the work based on the PID tuning by
applying Z-N rule to get the optimized performance of control system based modeling
of human cardiac muscle. The another aim of this paper is the addition of pole at
origin in plant along with PID controller to increase the type of open loop transfer
function of plant as steady state error for any input test signal reduces with the
increment of type of a system. Due to addition of pole, transient part may get
deteriorated as order increases with the increment of type of plant. To balance this
fact, a proper PID controller has been introduced and designed by applying Z-N
tuning rule to get an output with better dynamic and static performance of the total
system. At the end of this work an OP-Amp based practical implementation of PID
controller has been done to calculate the controller parameters in terms of resistance
and capacitance for real life application.

Abstract:

A remarkable year was 1905 in physics and astronomy when Einstein first
proposed the special theory of relativity. This theory is the foundation of modern
astronomy and astrophysics. This theory was also the foundation of the theory of
general relativity proposed by Einstein in 1915 to incorporate gravity into the system.
Thus, the special theory of relativity already became of supreme importance in
physics since the beginning of nineteenth century and it continues to be the right from
the word go theory in modern physics. An attempt is made in this paper for a
deliberate and comprehensive derivation from an equation of the special theory of
relativity. The derivation is made with an aim to look deep inside of the theory of
special relativity to conclude a comprehensive conclusion. Also some conceptual
modifications are arranged to justify the conclusion. The physical time, mass and
velocity are related in some equations in this paper.

Factors Affecting the Performance of Construction Projects in Pakistan

Authors:

DOI NO:

Abstract:

There is a French dictum “when the construction industry prospers
everything prospers”. Construction, a term that encompasses activities related to the
creation of physical infrastructure and related activities, plays a crucial role in the
economy of any country with estimated share of 40-60 % in gross fixed capital
formation and having linkage of more than 60 other associated industries. Today,
construction is the second largest sector in Pakistan’s economy after agriculture.
Roughly 30-35% of employment is directly or indirectly affiliated with the
construction sector.
In Pakistan, a Construction Project can be categorized as high risk as it is
very complex and involves a variety of stakeholders looking after their own interests.
In order to make sure that the projects are completed within the key measures of
budgeted cost, allocated time and required quality, identification of causes affecting
the project performance is very much necessary so that stakeholders can take
proactive steps to avoid such situations and manage effectively and systematically to
achieve the project performance objectives of time, cost and quality.
The purpose of this Paper is to investigate the major obstacles and
constraints in the performance of construction projects in Pakistan. In this paper a
local construction project case study and facts which I observed during my 16+ years
of experience in dealing with construction projects are taken into account to
document the bottlenecks. The case study is the construction of Earth Dam Project in Tribal region of KPK, where I worked as a Resident Engineer. The project
performance has been suffered adversely equally by roles played by the design
consultant, the Employer, the supervisory consultant, the Contractor and country
political situation and regional security. Finally, main recommendations with
discussions are presented that will help to overcome the related obstacles and
hindrances in project performance in construction industry of Pakistan.
Similar methodology is adopted in Document of the World Bank Discussion
Paper Series: Technical Note:9 LOCAL CASE STUDIES November 2007, where
case studies of several past infrastructure projects in different sectors including
roads, airport, motoway and irrigation were reviewed to document the bottlenecks
which occurred during the various processes involved in the life cycle of
infrastructure projects. Identifying such processes allows a better understanding of
the capacity constraints in planning, designing, programming, procurement, contract

Abstract:

Concrete durability, strength, manageability, and economy have made it the
world’s most generally utilized development material. The term Concrete alludes to a
blend of totals, normally sand, and either (rock or smashed stone) coarse aggregates,
held together by a binder of cementitious paste. Concrete has great compressive
quality however almost no rigidity, subsequently constraining its utilization in
development. . Thus it needs assistance in opposing pliable anxieties caused by
twisting forces from connected burdens which would bring about breaking and at last
disappointment. Due to the increasing demands of concrete strength & ductility in
our modern day construction, increases the demand to address the importance of this
concept once again. As many techniques/researches has been carried to improve the
strength of concrete prior which has been successful to some extent but still increase
in the strength of plain cement concrete considered to be a future challenge. In this
research the focus on increasing the strength of concrete is by embedding steel
springs phenomena in the different zones of concrete samples are studied. Tension
and compression steel springs attached to base plate embedded in the concrete
samples, and are tested for compressive and tensile strength of the concrete. Results
shows that steel springs can be effective in the strength of concrete at specified zones.
Hence it is recommended using steel springs in the concrete at effective zones to
increase the strength of concrete.

Energy Efficient Backend Cluster Head and Fault Tolerance model for Wireless Sensor Networks

Authors:

DOI NO:

Abstract:

Fault Tolerance and energy consumption are the constraints in designing
Wireless Sensor Network’s (WSN’s) while most of the Base station’s designed are
based on energy usage whereas medical care systems need fault tolerant systems. In
previous works, numerous clustering procedures are intended for network clustering.
There doesn’t exist any recovery methods in the clustering procedures in case if CH
node fails. Since the load is enlarged at the CH nodes, the energy depletion occurs
more quickly which results in CH failure. Centered on the proposed technique,
distance and residual energy are the two parameters that are considered to select
BKCH. This BKCH which act as CH aggregates the data and send them back to the
BS when there occurs a failure in the elected CHs. For solving the problems
produced by faults of Cluster Heads, an Energy efficient Backup Cluster Head Fault
tolerance (EE-BKCH-FT) is offered. We present two strategies to find the optimal
position of BS’s: 1) low energy usage while transmission 2) low energy usage when a
CH fails. Considering weight factor and the above conditions the position of a CH is
decided as fault tolerance is highly recommended as to increase network lifetime
which can sustain in any environmental conditions even if CH failures happen.
Simulation results given by NS2 software are utilized to verify the efficiency of
proposed method compared to the surviving approaches.

Pairing-free Partially Blind Message Recovery Signature Scheme with Application To Online e-Cash Payment System

Authors:

DOI NO:

Abstract:

Blind signature plays a significant role in practical applications such as ecash
and e-voting systems, where anonymity is of great importance. A partially blind
signature enables a signer to explicitly incorporate a pre-agreed common
information into a blind signature without the loss of blindness property. In recent
years, many cryptographic researchers have made substantial progress in the design
of blind signature schemes. In order to improve the efficiency, in this paper, we
propose a new pairing free partially blind signature scheme with message recovery in
the identity-based frame work. The proposed scheme is existentially unforgeable with
the assumption that the Elliptic Curve Discrete Logarithm Problem (ECDLP) is hard.
We compare our scheme to the well known existing identity-based partially blind
signature schemes. With pairing free realization and the message recovery features,
the proposed scheme is more efficient in terms of computation and communication
point of view. Finally, we present an electronic-cash payment system based on our
PF-IDPBS-MR scheme.

energy consumers in Pakistan. The institute budget for energy cost has assumed to be
the major costs and minimizing the energy bill in a large institute has become a big
challenge. The targeted actions can be used to minimize the electricity consumption.
The savings on energy provides a chance to reinvest it for the institute. In this work,
energy assessment of Government College of Technology (GCT) campus Bhakkar is
done to identify potential energy savings and to enhance the awareness,
responsiveness for energy conservation amongst the community of the campus. The
data about the installed load is collected by visiting each department. This work

Abstract:

The paper is intended to investigate the foster effects of political instability,
leadership influence, experimentation and budget constraints responsible for poor
performance and feedback from public sector organizations. Keeping in view the
purpose of the study, the research framework for the study is descriptive. Firstly,
Primary data is collected through questionnaires from individuals engaged with
public sector organizations. Secondly, unstructured interviews conducted to explore
the effect of Artificial intelligence. Through research analysis, the empirical evidence
suggest that the innovation activity is intrigued with important conditions responsible
for the performance of public sector organization. Political instability suggested
negative significance while others have demonstrated positive significance
concerning innovation reforms. Artificial Intelligence also demonstrates a strong
scope for future public sector organizations. In the following research framework, the
data is based on the judgments of employees engaged with public sector
organizations. The responses are individual self-reported and not objective, so there
is a fair possibility that response would be biased. Furthermore, the responses are
from Pakistan’s main cities which cannot be generalized to various countries. This
study focuses on the performance of the public sector organization. A large amount
of literature has emerged on the likelihood of innovation reforms for private sector
firms over the course of time. This paper is widening the horizon to study the
likelihood of innovation reforms for public sector organizations by adhering the
innovation culture and identifying important factors which may influence. The paper
also provides a base for finding more dimensions to implement innovation reforms
and also guide policymakers to execute efficient policies. Furthermore, the study is
based on questions covering “what” and “how” dimensions. This type of quantitative
study lacks for “why” dimension. Therefore, semi-structured interviews and case
analysis could explain more regarding innovation reforms. The research framework
is the first attempt to examine the impact of different conditions on the
implementation of innovation and Artificial intelligence influence in public sector

VSM Based Models and Integration of Exact and Fuzzy Similarity For Improving Detection of External Textual Plagiarism

Authors:

DOI NO:

Abstract:

A rapid growing has occurred for the act of plagiarism with the aid of
Internet explosive growth wherein a massive volume of information offered with
effortless use and access makes plagiarism − the process of taking someone else’s
work (represented by ideas, or even words) and representing it as his own work −
easy to be performed. For ensuring originality, detecting plagiarism has been
massively necessitated in various areas so that the people who aim to plagiarize
ought to offer considerable effort for introducing works centered on their research.
In this paper, a work has been proposed for detecting textual plagiarism
focused on proposing models for both candidate retrieval and detailed comparison
phases. Firstly, for the candidate retrieval, two models have been proposed
established on adopting the vector space method VSM as a retrieval model wherein
these models base on offering different representations for text documents. The first
model centers on representing documents as vectors consisting of average term
𝑡𝑓 − 𝑖𝑠𝑓 weights instead of representing them as vectors of term 𝑡𝑓 − 𝑖𝑑𝑓 weight.
Whereas, the second retrieval model assigns for each term constituting the document
a weight resulted from a weighted sum equation that sums this term 𝑡𝑓 − 𝑖𝑑𝑓 weight
with its average 𝑡𝑓 − 𝑖𝑠𝑓 weights and considers it as a query for retrieval. The
detailed comparison task comes as the second phase wherein a method has been
proposed that cores at the integration of two diverse similarity measures and the
introduction of one similarity measure involving them; Exact similarity and Fuzzy
similarity.
Experiments have been conducted using PAN-PC-10 as an evaluation dataset
for evaluating the proposed system. As the problem statement in this paper is
restricted to detect extrinsic plagiarism and works on English documents,
experiments have been performed on the portion dedicated for extrinsic detection and
on documents in English language only. These documents have been randomly
separated into training and testing dataset. The training data has been used for parameters tuning whereas evaluating the performance of the proposed system and
comparing it against the existing methods have been performed using testing dataset.
For evaluating performance of the models proposed for the candidate retrieval
problem, Precision, Recall, and F-measure have been used as an evaluation metrics.
The overall performance of the proposed system has been assessed through the use of
the five PAN standard measures Precision, Recall, F-measure, Granularity and
𝑃𝑙𝑎𝑔𝑑𝑒𝑡 . The experimental results has clarified that the proposed system either
comparable or outperforms the other state-of-the-art methods.

Abstract:

Now a day’s fingerprint techniques are widely used in authentication systems,
therefore its privacy protection becomes an important issue. Securing a stored
fingerprint template is very important because once fingerprints are compromised, it
cannot be easily revoked. So, we review here a new system for preserving fingerprint
confidentiality. In this system, the fingerprint privacy is maintained by combining two
special fingerprints keen on a original identity. In the enlistment phase, two fingerprints
need aid taken from two different fingers. We acquire the minutiae positions
about one fingerprint, the introduction from claiming another fingerprint, and the
reference focuses starting with both fingerprints. In view of those gotten information,
a joined minutiae format may be created Also saved previously, a database. In the
Confirmation phase, we utilize the fingerprints of the same fingers that need aid at
that point utilized within enlistment stage. For same 2 finger prints against a mutual
minutiae template, a two-stage fingerprint matching process is used. By storing the
combined minutiae template in the database, the complete minutiae characteristic of
a single fingerprint will not be compromised when the database is stolen by the attackers.
The joined minutiae format will be changed over under a real-look indistinguishable
joined together finger impression by utilizing existing finger impression
reproduction approach. These effects under another virtual character to those two

Protein sequence comparison under a new complex representation of amino acids based on their physio-chemical properties

Authors:

DOI NO:

Abstract:

The paper first considers a new complex representation of amino acids of
which the real parts and imaginary parts are taken respectively from hydrophilic
properties and residue volumes of amino acids. Then it applies complex Fourier
transform on the represented sequence of complex numbers to obtain the spectrum in
the frequency domain. By using the method of ‘Inter coefficient distances’ on the
spectrum obtained, it constructs phylogenetic trees of different Protein sequences.
Finally on the basis of such phylogenetic trees pair wise comparison is made for such
Protein sequences. The paper also obtains pair wise comparison of the same protein
sequences following the same method but based on a known complex representation
of amino acids, where the real and imaginary parts refer to hydrophobicity properties
and residue volumes of the amino acids respectively. The results of the two methods
are now compared with those of the same sequences obtained earlier by other
methods. It is found that both the methods are workable, further the new complex
representation is better compared to the earlier one. This shows that the hydrophilic
property (polarity) is a better choice than hydrophobic property of amino acids
especially in protein sequence comparison.

Effect of Thin Layer on Bearing Capacity in Layered Profile Soil

Authors:

DOI NO:

Abstract:

Bearing capacity is the main criteria for designing the foundation of a
structure. Several theories and experimental methods have been propounded by many
researchers for computing the bearing capacity parameters separately. Traditional
bearing capacity theories for determining the ultimate bearing capacity of shallow
foundations assume that the bearing stratum is homogenous and infinite. However
this is not true in all cases. Layered soils are mostly encountered in practice. It is
possible to encounter a rigid layer at shallow depth or the soil may be layered and
have different shear strength parameters. In such cases shear pattern gets distorted
and bearing capacity becomes dependent on the extent of the rupture surface in
weaker or stronger material. The best estimation of bearing capacity on layered soil
are possible only, if the pressure-settlement characteristics of the foundation-soil are
known for the size of the footing. From the review of literature, it may be noted that
the bearing capacity equations proposed for the homogenous soils by Terzaghi
(1943) and Meyerhof (1951) are not applicable to layered soils. Hence it is necessary
to develop an equation for predicting the bearing capacity of granular layered soils.
In present investigation, plate load test have been conducted in a large tank to
observe the load settlement behavior of plates of different sizes resting on layered
granular soils. Tests were conducted on two layers of soils. Fine gravel layer
overlain sand layer were tested using mild steel plates of square shapes. The effect of
the placement of layers on the bearing capacity characteristics of footing, has been
studied and an equation for predicting the bearing capacity of two layered granular
soils is developed based on the plate load test data.

has been partitioned from the father’s chromosome structure. It initially preprocesses
the image of the son using the collaborative filtering for making it look different from
the input image to show the similarity between the father and the son. It then detects
the edge of the structure after preprocessing it using the SOBEL edge recognition
calculation. The SOBEL edge discovery calculation is that the inclination of the
picture is determined for every pixel position in the picture .After detecting the edges
of those input images, matching process starts between the input image and the list of
father chromosome images. Then the matched output appears. In order to predict the
diseases which is yet to come in future for the son is represented graphically by
dividing it into three colors, firstly green represents there is less possibility of the son
getting the disease, secondly yellow represents there may be any chance of son
getting the disease and finally red represents there is high possibility of son getting

Abstract:

Because of the accessibility of recoverable petroleum product holds and the
natural issues brought about by the utilization of these non-renewable energy
sources, much consideration has been given to the creation of biodiesel as a
substitute for oil diesel. The two most normal kinds of biofuels are ethanol and
biodiesel. Be that as it may since biodiesel comprises of vegetable oils and creature
fats, it is to be expected that biodiesel crude materials can contend with long haul
nourishment supplies. In this way, consideration has concentrated on oilseeds that
produce non-eatable oil as a wellspring of biodiesel generation. In this undertaking,
the citronella of plant species (Cymbopogon flexuous) is portrayed as another
wellspring of unrefined petroleum for biodiesel generation. Lemongrass is local to
India and tropical Asia. In India, it develops along the western ghats (Maharashtra,
Kerala), Karnataka and Tamil Nadu, alongside the lower regions of the Arunachal
Pradesh and Sikkim slopes. This investigation analyzes the exhibition of citronella oil
and its blends as fills for pressure start motors. The information in this way got was
contrasted and the information got utilizing diesel. The motor worked very well
without burning issues. We prescribe the utilization of citronella oil and its blends as
elective powers for diesel motors. In any case, since biodiesel comprises of vegetable
oils and creature fats, it is to be expected that biodiesel crude materials can contend
with long haul nourishment supplies. Along these lines, consideration has
concentrated on oilseeds that produce non-palatable oil as a wellspring of biodiesel
generation. In this way, the commitment of non-sustenance oils as non-nourishment
wellsprings of vegetable oils to biodiesel generation would be significant.

The constrained mechanical systems by quasi-coordinates are more universal than by generalized coordinates. In this paper, the motion equations of nonconservative singular mechanical systems by quasi-coordinates in phase space are studied. The regularization forms of Boltzmann-Hamel equations for general holonomic and nonholonomic singular mechanical systems are derived. The results show that the canonical equations expressed by quasi-coordinates and quasivelocities have a completely single structure, which do not depend on the constraints or not. The nonholonomic singular mechanical system is a natural extension of the general holonomic singular mechanical system.

Abstract:

In the world today computer networks have a very important position and most of the urban and national infrastructure as well as organizations are managed by computer networks, therefore, the security of these systems against the planned attacks is of great importance. Therefore, researchers have been trying to find these vulnerabilities so that after identifying ways to penetrate the system, they will provide system protection through preventive or countermeasures. SVM is considered as one of the major algorithms for intrusion detection. One of the major problems is the time of training and the need to improve its efficiency when it comes to work with large
dimensions. In this research, we try to study a variety of malware and methods of intrusion detection, provide an efficient method for detecting attacks and utilizing dimension reduction. Thus, we will be able to detect attacks by carefully combining these two algorithms and pre-processes that are performed before the two on the
input data. The main question raised in this study is how we can identify attacks on computer networks with the above-mentioned method. In anomalies diagnostic method, by identifying behavior as a normal behavior for the user, the host, or the whole system, any deviation from this behavior is considered as an abnormal behavior, which can be a potential occurrence of an attack. In this research, the network intrusion detection system is used by anomaly detection method that uses the SVM algorithm for classification and SVD to reduce the size. The various steps of the proposed method include pre-processing of the data set, feature selection, support vector machine, and evaluation. The NSL-KDD data set has been used to teach and test the proposed model. In this study, we inferred the intrusion detection using the SVM algorithm for classification and SVD for diminishing dimensions with no
classification algorithm. And also the KNN algorithm has been compared in situations with and without diminishing dimensions and the results have shown that the proposed method has a better performance than comparable methods.

Finite Element Simulation of Thermal Behavior of Dry Friction Clutch System during the Slipping Period

Authors:

DOI NO:

Abstract:

Most of failures in the friction clutches occur due to the excessive heat generated due to friction between various parts, and this heat causes high temperatures leading to high thermal stresses. In the present research paper,
numerical simulation had been developed using finite element method to simulate the thermal behavior of the dry friction clutch. Three-dimensional finite element model was made and analyzed using ANSYS/Workbench sofware18. The friction clutch system was firstly modeled mathematically and solved numerically to determine the transient thermal response of the clutch disc. The two fundamental methods of uniform wear and uniform pressure are assumed. The applied torque during the sliding period was constant. The temperature and heat generated were estimated for each clutch part (pressure plate, clutch disc and flywheel) using heat partition ratio. The assumptions that are inherent in the derivation of the governing equations are presented which followed up by the appropriate boundary conditions. The results show that the maximum temperature values for uniform pressure condition are
greater than those for uniform wear condition. Also, the temperature value increased with time and approximately reaches the highest value at the middle of the sliding period when the applied torque is constant with time and then decreased to the final values at the end of slipping period.

Investigating the behavior of steel structures with honeycomb damper against blast and earthquake loads

Abstract:

Earthquake is one of the most important natural phenomena and humans
have always been trying to control its adverse effects. In the past century, the
development of cities and the high investment in them and many financial and life
losses caused by earthquake and, on the other hand, the ever-increasing advances in
science and technology that allow for more accurate knowledge of the factors causing
the earthquake and how to control it have made humans reduce its financial and life
losses by making suitable and earthquake resistant structures. Today, due to the
increasing growth of terrorist activities, the risk of structures facing blast loads has
also increased. The occurrence of various terrorist incidents in relation to important
structures around the world has caused that in recent years, blast loads become the
focus of special attention. This article examines the connection of steel structures
with honeycomb damper by applying blast and earthquake loads in Abaqus finite
element software. Three frame models with 6, 9 and 13 floors have been considered
for the study. For air blast, 10 Kg of TNT have been used. To apply earthquake
records, seven pairs of accelerograms have been employed. By examining the results
of numerical modeling in Abaqus finite element software, it can be observed that as a
result of applying blast load, the damper could not react. But due to applying
earthquake records, the damper’s behavior was very good so that at the beamcolumn
joint, the highest amount of stress was created in the damper. Considering
that applying the blast loading occurs in less than a few milliseconds and the
structure does not have enough time to react to this load, blast load failure has been
local and sectional.

increases the exterior area of the nano-membranes. The resultant membrane is
tendbal and instinctivelyrobust enough to resist filtration under high stress. The
synthesized nanofibers are further analyzed and characterized by using spectroscopy
(UV-Vis), Fourier Transform Infra-Red spectroscopy (FTIR) and Scanning Electron
Microscope(SEM).The SEM, UV-vis and FTIR result shows the filtration rate of the
fabricated membrane could capably exclude nanoparticles with different sizes (from
10 to 100 nm in diameter) from a feed solution.

How the Higgs Field Effects the Wave Propagation of Waves as Wavy Resembles a Sine Wave. Why Astronomical Particles have Relationship between Shape (Elliptical) and Orbit (Elliptical).

Authors:

DOI NO:

Abstract:

The space is filled with Higgs fields. As other fields like electric fields or
magnetic fields, Higgs fields are of elliptical shape. Higgs fields are small individual
fields represent a tiny part of space. Every adjacent Higgs Fields have opposite
rotations, the repulsive force makes them to have unique identity for themselves
which makes free space highly stable. Opposite rotation is the reason that any two
Higgs fields do not mingle with each other to form larger field in free space, but
under the influence of ordinary matter like Earth, Higgs fields change their
orientations to be unidirectional to form a larger field called gravity. The larger the
mass, the higher the number of Higgs fields to have unidirectional orientations. The
force carrying particle Higgs Boson is responsible for Higgs field and the force
carrying particle graviton is responsible for gravitational force. The unidirectional
orientations of many small oval shaped Higgs Boson yields the graviton which has
oval shape too. Thus, Higgs Boson and graviton are same force carrying particle
acting differently at different situations. For example, stationary charge gives electric
field where as moving charge gives magnetic field. The phenomenon of both is
basically the same but looks different due to movement. Maxwell realized that the
phenomenon of both is the same with the same force carrying particle but act
differently at different situations. In this paper we will find, why wave propagations of
waves are wavy. We will also find why the shape and orbit of astronomical objects
are of similar pattern – elliptical or oval shape.

The Constructive Implementation of New Applications of Fuzzy Languages and Fuzzy Automata Ƒ * – Pure Semi groups for Generating Theorems

Authors:

DOI NO:

Abstract:

Introducing the idea of Ƒ* – pure semi group and shows that a semi group ‘S
‘is regular and Ƒ* – pure iff ‘ S ′ is a semi lattice of groups. Also shows with the
purpose of a semi group’ S ′ be Ƒ* – pure iff S3 is a semi lattice of groups.
Additionally, learning the group congruence’s as well as semi lattice congruence’s
on such a semi group and give a number of properties of fuzzy congruence’s on Ƒ* –
pure semi groups. A nonempty set X, a fuzzy subset of X is, by definition, an arbitrary
mapping A: X → [0,1], where [0,1] is the usual interval of real numbers. The
important concept of fuzzy automata set position onwards by Zadeh [I]. Has opened
up keen insights and applications in a wide range of scientific fields. It offers tools
and a new approach to model imprecision and uncertainty present in phenomena that
do not have sharp boundaries. Since then, a series of research on fuzzy automata sets
has come out expounding the importance of the concept and its applications to logic,
set theory, algebra theory, real analysis, topology, etc. [III]. Fleck A. C. used the
notion of a fuzzy subsets of a set to introduce the notion of fuzzy group of a group,
Rosenfeld’s paper motivated the development of fuzzy algebras [X]. Following the
formulation of fuzzy subgroups by Rosenfeld, Dib introduced the concept of a fuzzy
automata space as a replacement for the concept of universal set in the ordinary
case. Recently, some basic concepts of fuzzy algebras such as fuzzy homomorphism’s
were introduced and discussed by using the new approach of fuzzy space and fuzzy
automata groups introduced. In this paper we introduce concepts of fuzzy automata
inverse semi groups and redefine fuzzy automata inverse sub-semi groups using the
concept of fuzzy spaces introduced by K. A. Dib [II].

Impact of Jelly Fish Attackonthe Performance of DSR Routing Protocol in MANETs

Authors:

DOI NO:

Abstract:

Mobile Ad-hoc Networks (MANETs) could be setup frequently without the
need of pre-established infrastructure. The nodes in MANETs are free to move and
they can join as well as leave the network. Due to the dynamic nature of nodes in
MANETs, routing protocols in MANET are extremely vulnerable to different security
attacks. Like other different security attacks, Jellyfish attack is one of the most
dangerous attacks in MANETs environment and it degrades the overall performance.
In such type of attack, the packets reached its destination but take more time and
hence it is difficult to detect such attack. In this research paper, we have analyzed the
performance of Dynamic Source Routing (DSR) routing protocol in the presence of
Jellyfish attack. To evaluate the performance we have created different scenarios
having various number of Jellyfish attacks in MANETs environment. From the
simulation result, it has been observed that Jellyfish attack significantly degrades the
performance of DSR protocol in terms of end to end delay, throughput and packet
delivery ratio. Moreover it has also been observed that when the number of Jellyfish
attacks increases in the network then the performance is further degraded. In this
research OPNET Modeler 14.5 simulator has been used in order to assess the
performance of Jellyfish attack in MANETs environment.

Medical Image Fusion based on Hybrid Algorithms for Neuro cysticercosis and Neoplastic Disease Analysis

Authors:

DOI NO:

Abstract:

A Neuro cysticercosis is avoidable parasitic infection caused by larval cysts
of the pork tapeworm. The larval cysts can affect different parts of the human organs
causing a condition known as cysticercosis which can direct to seizures it is called
neuro cysticercosis. A neoplasm is an abnormal growth of cells in the brain, also
known as a tumor which causes growth of tumor triggered by DNA mutations within
your cells. The neoplastic disease causes two types of tumor growth. The benign
tumors usually grow which grow slowly and cannot spread to other tissues are called
as noncancerous growth. The Malignant brain tumors grow quickly and spread to
multiple tissues, organs are known as cancerous growth. In spite of huge progresses,
still there is no single modality which can represent all aspects of the human body. In
this paper a novel method has been proposed for Dual tree complex wavelet
Transform (DTCWT) with Non-subsampled shearlet transform (NSST) hybrid fusion
algorithm. The developed fusion algorithm is experienced on the pilot study datasets
of patients affected with Neurocysticercosis and neoplastic diseases. The fused image
conveys the superior description of the information than the source images.
Experimental results are evaluated by the number of well-known performance
evaluation metrics.

Numerical Simulation of the effect of simple and T-shaped dikes on turbulent flow field and sediment scour/deposition around diversion intakes

Authors:

DOI NO:

Abstract:

The interaction of flow patterns with the movements of live bed of natural
channels is a complex 3D process which requires precise investigation in different
scenarios to be fully understood. This study effort to investigate the flow patterns and
its effect on the formation of scour holes and deposition stacks in the vicinity of a
diversion channel entrance considering the presence of a single dike with various
lengths normal to flow and different simple and T-shaped models. Results indicated
that Dike shape and its length normal to flow significantly affects the ratio of diverted
discharge, volume of sediment transport into the diversion channel, and volume and
depth of the scour holes as well as the shape, height and location of the formation of
the deposition stack. Increasing the length of wing for the T-shaped dikes could
decrease the depth and span of the scour holes efficiently as well reducing the
dimensions of deposition stack to form out of the diversion channel.

Applications of Fractal and Quasi Fractal Geometries in Slot Antenna Design: A Review

Authors:

DOI NO:

Abstract:

Fractals stand for unique geometries that can be nice-looking for microwave
circuit scholars. Latest expansions in wireless communication systems have been
caused different experiments to manufacture high-grade diminished components.
These experiments motivate microwave circuits and antennas engineers to look for
solutions by examining diverse fractal structures. Nonetheless, there are several
relevant limits of fractal antennas involving geometric restrictions, low gain, fractal
orders and design complexity. These limits are feasibly solved by restructuring
methods as in fractal reconfiguration and like pre-fractal structures. These methods
have been known as semi or quasi-fractals that can be applied to antenna design
without endless scale. Accordingly, quasi-fractal geometry with limited orders or
iterations can be exploited for a specific dual/multiband antenna based on a
particular fractal iteration.
In this study, the unique properties of fractal geometries will be presented
together with the most commonly used fractal geometries applied in the slot antenna
design. In this respect, the application of fractal geometries in the slot antenna design
can be classified into two categories. In the first category, the fractal geometry is
applied directly such that it constitutes the whole slot structure, while in the second
one; the fractal geometry is applied indirectly. In this case, there is a slot structure
with Euclidean shape, such as triangle, square…etc., and fractal geometry has to
replace each line segment in this structure. In addition, slotting processes by fractal
or semi fractals in the ground plane of antenna substrates to produce dual or
multiband or even wideband response have been discussed in this review paper.

If Space and Time are the Necessary Conditions for Sustaining the Universe, then, Mass and Energy are the Sufficient Conditions for the Universe. One Condition can be Smoothly Transformed into the Other Conditions and Vice Versa

Authors:

DOI NO:

Abstract:

Space and time are the necessary conditions for sustaining the Universe
whereas mass and energy are the sufficient conditions for sustaining the Universe. All
conditions are in almost balanced state but not in absolute balanced state. Little
imbalance is maintained by the Universe to sustain the Universe as the way it is now.
That is why, the Universe is almost peaceful, but not absolute peaceful. Only we can
attain an absolute peaceful Universe by stopping the time in the forward direction
(positive direction, the way it is now). The rate of change of anything in time is called
evolution. If time stops running, everything will be at absolute rest without any
evolution. This is a theoretical abstract idea only because it has no practicality or
feasibility in the present state of the Universe. Speed is a function of space and time.
It can be easily shown that time is a sinusoid and it loses its frequency of oscillations
with the interaction with mass which increases time period, which can be termed as
time dilation. The time period is extremely large of time, and the peak of the temporal
magnitude is extremely low. Thus, frequency is extremely low. This is the reason,
there are hardly any differences of time on Earth compare to free space. Even the
astronomical body has very negligible effect on the time period or frequency of time.
But time period gets larger with effect of mass, thus, time slows down (due to time
dilation), which implies that frequency decreases little bit due to the effect of mass on
time. Due to the slight variation in magnitude in a very low frequency sinusoid (time),
time runs in the forward direction, as it is now in the present Universe. Thus, space
and time are the necessary conditions for sustaining the Universe whereas mass and
energy are only sufficient conditions for sustaining the Universe, the way it is now.
All these four entities are the key for the Universe to get the present shape, the way it
is now. Any change in one condition can lead the Universe to entire different shape
with compare to the present shape. Thus, the Universe is at knife edge accuracy but
not at absolute accuracy. Any one condition can be smoothly transformed into the
others and vice versa.

Abstract:

In this paper, thermal pyrolysis nanocoating technique was used to coat the brass
alloy (grade B-111) of heat exchanger that used in Midland Refineries Company-
Iraq. The nanocoating specifications and surface characterization have been made by
using many measuring techniques; Atomic Force Microscopy (AFM), Scanning
Electron Microscopy (SEM), and X-ray Diffraction (XRD). From AFM results, it was
observed that the particle size of nanocoated brass substrate was 70 nm. From XRD
results it was showed high crystalline thin films. On the other hand, the SEM results
showed good smooth surface morphology films. The corrosion behavior of with and
without nanocoated brass tubes achieved by study the open circuit potential,
corrosion current density and corrosion potential which are used to determine the
corrosion rates in 3.5M of sodium chloride solution. The results indicated that
nanocoated substrate showed insignificant weight losses in comparison to that of
uncoated substrate. So minimum weight loss with CuO nanocoating with thermal
pyrolysis technique at 0.04M was 2.5*10-2 mm/year.
