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.

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:

The structure of supportable wireless-sensor-network’s(W/S/N’s) is an extremely testing matter From single perspective, vitality compelled sensors are relied upon to run self-sufficiently for extensive stretches. Be that as it may, it might be cost-restrictive to supplant depleted batteries or even outlandish in threatening situations. Then again, in contrast to different systems, WSNs are intended for explicit applications which run from little size medicinal services reconnaissance frameworks to extensive scale natural checking. Along these lines, any WSN sending needs to fulfil a lot of necessities that contrasts starting with one application then onto the next. In this unique circumstance, a large group of investigate occupation have been directed so as to suggest a wide scope of answers for the vitality sparing issue. This exploration covers a few zones going from a top-down review. Here we plan a design for WSNs utilizing turbo decoder. We deteriorate the LUT-Log-MBCJR design into its most essential add/compare/select (A/C/S) tasks also execute them utilizing a novel low-multifaceted nature ACS component. At that point we present another order of energy preservation strategy found in the ongoing writing, trailed by a deliberate discourse concerning how these plans struggle with the particular prerequisites. At long last, we study the methods linked in W/S/Ns to achieve exchange off flanked by a variety of prerequisites, for instance, multi-target streamlining.

Abstract:

Conventional clay bricks are heavier in weight which increase the overall dead load of the structure. Its formation creates smoke, loss of agricultural land and high energy consumption. To avoid these problems, Lightweight concrete is used in the construction due to its applications such as reduction of dead loads, seismic loads, environmental pollution and labor cost. In this study, the lightweight concrete is used to make lightweight concrete bricks/blocks. The lightweight materials used are; shale aggregate, expanded polystyrene and gypsum, paper pulp. The compressive strength and weight test of the samples were carried out. The papercrete was selected because of its lightweight, reasonable price and local availability. The results indicate that the papercrete bricks are 15% lighter in weight than conventional clay bricks. Due to low compressive strength these bricks are acceptable only for non-load bearing walls and are potentially ideal material for earthquake prone regions

Abstract:

Pakistan annually produces approximately 50 Million tons of sugar cane and most of it is used for production of sugar. The industrial waste of sugar cane, known as bagasse, is mostly used as fuel for power generation in the same sugar industry. We have to study the properties of sugar cane bagasse ash in concrete, the main variables in this study are the amount of sugar cane bagasse ash (0, 5, 10, 15, 20 and 25 percent by weight of cement) as a partial replacement of cement in concrete. We conclude that to improve the quality and reduce the cost of construction material. The importance of this work is to make sugar cane bagasse ash (SCBA) as a construction material.

Abstract:

Around the world, governments at all levels take part very important roles in organizing the safety and comfort of public transportation systems in the form of BRTs. Huge Construction projects such as BTR are initiated in intricate and dynamic conditions bringing about conditions of high vulnerability and risk, which are compounded by challenging phase restrictions. Constructions of BRT’s have reformed suggestively from the past numerous years. It is a structure obsessed primarily by govt. Sponsors. It is exposed against the several specific and trade risks that habitually speak to more remarkable publicities than those that are conventional. In this manner risk assessment requires develops. Risk taxation is an apparatus to classify those hazards in a task and direct it as requirements be with suitable management. Risk assessment is considered in this research as a strategy that expects to distinguish and appraise those important risks which are related to design, financial and management. The common procedure of this research rest on to a great extent on the review survey which was collected from the client, consultant and contractors of projects. A careful literature review was directed to distinguish the risk issues that influence the enactment of BRTs in general. The inspection questionnaire was designed to investigate the cross sectional behavioral arrangement of construction risks related to the BRT Peshawar. This research wants to classify and evaluate the risks and to improve a hazard supervision framework which the clients/ consultants/ contractors can implement when tightening BRT work in Pakistan.

Abstract:

Programming support is a foremost characteristic from claiming programming improvement existence cycle; henceforth prior close estimation from claiming fill in to maintainability assumes a vibrant part. For large portions quite some time now, product professionals bring been gathering measurements from source book clinched alongside a exertion on superior see those product they would Creating alternately evolving. Maintainability list (MI) will be a composite metric that incorporates an amount for universal source book measurements under a solitary amount that demonstrates relative maintainability. Similarly as initially recommended the mi is comprised of weighted Halstead measurements (effort or volume), McCabe’s Cyclamate Complexity, lines for code (LOC), & number about remarks [1, 2]. Two equations were presented: person that viewed as remarks & particular case that didn’t.
The improvement about Open Source system(OSS) is generally unique in relation to that proprietary product. In the OSS improvement situation an absolute designer alternately assembly of developers composes those source book for those initially adaptation of the product & make it uninhibitedly accessible through the web. After that different developers are welcome to help the existing code to its next discharge. Settling on that source book of the product accessible on the web permits developers around the reality to help code, include new functionality, change of the existing source book and submitting bug fixes of the present discharge. Over such a product improvement situation the upkeep of the open sourball product may be a culprit errand. Creating an OSS framework infers an arrangement from claiming incessant upkeep deliberations for debugging existing purpose & including new purpose of the programming framework. Those transform for settling on the adjustments should programming frameworks after their main discharge is known as support procedure. Those haul maintainability may be nearly identified with those programming upkeep on account of maintainability implies those effortlessness to perform upkeep of the framework. Suggested agenize based approach is give acceptable those cosset effective, productive Also exact answers for assess the programming (web application) RMA measurements including the screening to cloud registering administrations that methods “Testing/Debugging Similarly as An administration Evaluation”. Proposed system has performs faster and produce more accurate results to assure the quality of the software related to the non-functional metrics such as RMA (Reliability, Maintainability and Availability). Obtained result are outperform as compared to existing methods.

Abstract:

Labor productivity is among the most critical factors that heavily impact the achievement of a construction projects. In construction sites, construction techniques, construction organization, human resource management, working conditions and worker personal characteristics have significant effects on the labor productivity. Formwork, among others, is a common task in every construction project. This paper presents the measurement of labor productivity by work sampling method for floor and beam formwork of high-rise buildings in Ho Chi Minh City, Vietnam. The research identifies the proportion of time consumption for effective tasks, supportive tasks, and ineffective tasks of formwork as follows: 32%, 35%, and 33% respectively. In other words, the change in the proportion of ineffective work over periods of time through a working day enables a conclusion that the labor productivity of floor and beam formwork workers begins low, then

Abstract:

In the present paper we have studied the applicability of Initial rise (IR) and Peak shape(PS) methods for calculation of activation energy for saturated and unsaturated thermoluminescence peaks in the frame work of OTOR and IMTS
models. This peaks correspond to hyperbolic heating profile. It is shown as in the linear heating scheme that both IR and PS methods tend to underestimate the activation energies for TL peaks resulting from OTOR and IMTS models with
increasing filling ratio.
