Abstract:

Sedimentation has become a major problem in all over the world and especially in Pakistan. Discharge capacity of the canal has been reduced and the chances of overflowing in critical situations have increased. Cleaning of the sediments from canal require huge resources and the silt obtained after cleaning the reservoir not only will be wasted but will also cause pollution. In order to prevent the pollution and reduce the cost on the cleaning the reservoir, the silt is needed to be used beneficially to generate some revenue. We conducted this project to use this silt beneficially, in our case to manufacture artificial aggregate. A number of tests were performed to check the viability of artificial aggregates for being used in construction industry. Shape and particles size distribution properties of artificial aggregates are excellent but in properties like abrasion resistance, water absorption and compression strength artificial aggregates does not performs very well. However from the results it can be concluded that these artificial aggregates can be used as artificial light weight aggregates.

Abstract:

Amongst various health and risk associated issues, Road safety is also now treated as a Public health problem as per the recommendations of the World Health Organization (WHO). This is so particularly due to a significant increase in the number of traffic injuries. Pakistan is adversely affected by the problem of fatalities. It is the common practice that issues of crash prevention is not given consideration in the context of strategic planning. The safety issues are only dependent on imbalanced Police data governing general cause over speeding which is surely not at all. The research focuses on the operational model for mega city Karachi. The idea is designed to emphasize the trends including severity in road crashes, victims, and major arterials. The idea integrates a connection between Engineering and Management with the help of an exemplary system and provision of suitable infrastructure. Different year’s data record is manipulated only to hit way forward actions that can be chosen for prevention. On the contrary, mathematical justification is provided to correlate the Trauma surveillance model as a guideline in recommendations. The overall balance of research is maintained on the basis of ground realities and data modeling.

Abstract:

Electroplating and metal working industries discharges effluent that contains toxic heavy metals such ascopper (Cu(II)), nickel (Ni(II)) and zinc (Zn(II)) ions. Biosorption has been recognized as ahigh efficiency and low-cost alternative method that can be used to treat the industrial effluent for heavy metal removal. In this study , mature leaves of neem (Azadirachta indica) was used as the potential biosorbent to study its adsorption behavior of Cu(II), Ni(II) and Zn(II) ions from aqueous medium solution in single and multicomponent system. The biosorption experiment was carried out in a batch process at constant room temperature and initial heavy metal concentration. Optimal biosorbent dosage, pH and contact time for the biosorption process of the three metals were investigated. At optimal pH of 6 and biosorbent dosage of 0.2g, the maximum metal uptake for Cu(II), Ni(II) and Zn(II) were 34mg/g, 26mg/g and 37mg/g respectively. For single metal solutions, biosorption equilibrium data for Cu(II) and Zn(II) fit the Freundlich model, while Ni(II) fitted the Langmuir isotherm. In the multicomponent system, the Langmuir isotherm fitted well for the equilibrium data of mixed solution of Cu(II), Ni(II) andZn(II).

Abstract:

Clustering is the procedure of arranging things into teams whose participants are similar in some way. A cluster is consequently a collection of things which are comparable between them and also are dissimilar to the objects coming from various other clusters. As numerous kinds of clustering and also requirements for homogeneity or separation are of passion, this is a huge area. A prolonged survey is offered from a mathematical programming perspective. Actions of a clustering research study, kinds of clustering and criteria are discussed. In this paper, we recommend an estimate technique for time collection based on mathematical models.

Zeba Khanam, Md. Ayub Ali

DOI NO:

https://doi.org/10.26782/jmcms.2019.12.00039

Abstract:

Advance payment is the important issue in inventory analysis. Due to advance payment another important issue is the capital money. The main aim of this paper is to introduce advance payment concept in the analysis of inventory problem. Annual demand has been considered to developed this model. Also, we have considered the product deteriorate constantly after the certain time period. Due to advance payment supplier may offer to his retailers’ instalment facility. However, purchasing amount must pay before received the lot size. Shortages are allowed partially with the constant backlogging rate. Due to the high nonlinearity of the corresponding optimization problem, we cannot able to find the closed form solution of the objective function. To overcome this difficulties, we have used LINGO 18 software for solving the proposed inventory problem. To validate the proposed model, one numerical examples have been solved. Finally, the effects of changes of different parameters have been studied graphically of the proposed model and a fruitful conclusion has been drawn.

Abstract:

The transformer-less single-phase five-level Photovoltaic (PV) inverter is presenting in this paper. The Photovoltaic (PV) module is connecting to the proposed topology with different values of irradiation and temperature. The modelling of the PV cell is also representing in this research activity. The output voltage of the PV is stepped up by using DC-DC Boost converterfurther operation of the topology. The sinusoidal PWM control technique is proposed for this topology. Two reference sinusoidal signals are comparing by the magnitude of the carrier triangular signal for the generation of PWM pulses to the switches. The operating states of the proposed topology are explaining in detail. With the reduced switch inverter topology, the switching, conduction losses are reducing. This proposed topology will be simulated in MATLAB/SIMULINK to produce the output of five-levelwith the less number of switches.

Abstract:

A robust nonlinear control technique based on synergetic control theory is presented to extract maximum power of standalone photovoltaic system (SPV). The synergetic control makes the controlled system robust under the presence of system uncertainties and external disturbances such as variable irradiance and temperature. The designed control law guarantees the fast convergence towards the maximum power operating point origin without any oscillations. The PV system comprises of a PV source, power converter, maximum power point tracking algorithm and load. The simulations results show effectiveness of proposed method in comparison with Perturb and Observe (P&O) method under different atmospheric conditions such as variable solar radiation and PV cell temperature.

OBSERVABILITY AND REDUNDANCY BASED PMU PLACEMENT AT OPTIMAL LOCATION OF POWER SYSTEM

Authors:

P. Lakshmi Narayana, M Venkatesan

DOI NO:

https://doi.org/10.26782/jmcms.2019.12.00044

Abstract:

This paper investigates redundancy and observability constrained Sequential Quadratic (SQ) technique for optimal Phasor Measurement Units (PMU) placement. The nonlinear constraints of buses are considered with this approach to optimize the quadratic objective for PMU placement. Zero Injection (ZI) bus constraints are modeled in quadratic formulation to less PMU locations. PMU placement with and without ZI constraints are compared to illustrate the importance of ZI constraint modeling for PMU placement. Redundancy in network is estimated with number of branches connected to bus. Redundancy of bus network is measured by the proposed Bus Redundancy Index (BRI). To estimate observability performance of the complete network, a Complete System Bus Observability Index (CSBOI) is proposed. IEEE- 14,30, and 57 bus systems are simulated with the proposed constrained SQ Programming formulation in MATLAB. The comparison of planned way with conventional methods is also considered to show its efficacy

CAPACITOR BALANCING FOR MMCC-SSBC TOPOLOGY WITH NEGATIVE SEQUENCE CURRENT INJECTION METHOD

Authors:

DOI NO:

https://doi.org/10.26782/jmcms.2019.12.00045

Abstract:

This paper investigates the negative sequence current injection method for balancing the capacitor voltage in cascaded H--bridge D-STATCOM (MMCC-SSBC). Though the cascaded H -bridge D-STATCOM has the advantage of having less number of circuit components compared to Diode clamped and flying capacitor clamped D-STATCOM but the capacitor voltage balancing between the phase clusters is a main issue. Considering this problem the negative sequence current injection method is investigated under normal working condition of D-STATCOM as well as under large unbalance in the supply voltage. The performance of this technique is investigated by using MATLAB-SIMULINK modeling.

DEFENSE AGAINST LOAD REDISTRIBUTION ATTACKS CONSIDERING LOAD CURTAILMENT

Authors:

Kommoju C Sravanthi, Kotapuri Mercy Rosalina

DOI NO:

https://doi.org/10.26782/jmcms.2019.12.00046

Abstract:

In the present scenario of cyber-physical power grid, DC State Estimation (SE) plays a key role in the secure and reliable operation of power systems. Advanced communication and information technological devices like Remote Terminal Units’/Phasor Measurement Units’ measurement values are more prone to false/bad attack vectors. Those typical attacks that target SE are called False Data Injection Attacks (FDIAs) which can bypass classical detection methods. Load Redistribution Attacks (LRAs) are practical FDIAs that aim active bus power injections and active line power flows. Immediate LRAs lead to severe load shedding whereas delayed ones lead to load shedding and line outages too. To find the most damaging LRA vector, a bi-level mathematical optimization problem is framed, which represents attacker and defender. An optimal defense strategy is found by obtaining the Nash equilibrium on solving a two-player (attacker and defender) static zero-sum game considering load shedding as the utility function. The approach is analyzed on IEEE-30 bus test system, and attack and defense probabilities at Nash equilibrium are obtained.

The paper emphasis the importance of DTC for an induction motor with multi level inverter in order to reduce the frequency of switching for the IGBT’S for same hysteresis bands of torque and flux. The simulations were completed in SIMULINK software. Simulation results from conventional NPC-DTC and modified NPC- DTC are presented and compared. Results shows that torque, flux linkage and stator current ripples are decreased with proposed NPC-DTC strategy. Evaluation was made based on the motor performance, which are like reduction of switching cycles and improvement in flux responses.
