 Abstract

This paper traces the roots of Brahmin dominance that took place in Indian society. It basically focuses on the interpretation of historians, philosophers and great social reformers regarding the origin of the Shudras and Aryans. It is not an attempt to write the history of the varna system or caste system in India, but rather related to the contradictions on the issues of the origin of the Shudras and Aryans.

 Abstract

This paper presents different techniques for controlling of dynamic starting performance of three phase induction motor using voltage controller based soft starter. Controlling of torque is based on firing angle control of voltage controller and hence voltage input to induction motor. Different open loop and close loop strategies are presented. Finally a comparison among different controlling strategies is presented. MATLAB SIMULINK software is used to develop models and simulation results are used to comparing.

Abstract : Software testing has been established that testing, analysis and debugging prices typically consume over five hundredth of the prices related to the event of huge software systems. Several researchers have found many approaches to schedule associate order for execution. They incorrectly schedule tests and also the value is overrun throughout the prioritization method. To improve the regression testing process, test case prioritization techniques systematizes the execution level of test cases. One of the most critical activities of software development and maintenance, known as regression testing. Regression testing has been proved to be crucial stage of software testing. In our proposed study we introduce a hybrid firefly algorithm based regression test case prioritization. The major contribution of our study is regression test case generation, factors identification, clustering for test case prioritization, optimization of prioritized test case. In this research, the K-means clustering algorithm will be used to separate the relevant test cases from irrelevant test cases. Relevant test cases denote the prioritized test cases. We will consider only this relevant test cases resultant from the clustering algorithm in order to optimize it with Hybrid Fire Fly Algorithm (HFFA). HFFA works by the hybridization of Artificial Bee Colony (ABC) Algorithm and Fire Fly (FF) Algorithm. ABC algorithm is a part of a swarm based meta-heuristic algorithm which is enthused by the sharp foraging behavior of the honey bees. In our HFFA Optimization Algorithm, the FF will be processed within the scout bee component of ABC, which leads to fast convergence and limited search space controlled based optimization of locations. Thus we will obtain Effective prioritized test cases.

 Abstract

Bond strength is one among the important property of hardened concrete. Bond between the reinforcement and concrete influences the behavior of structural concrete in many respects. The quality and quantity of ingredients used for making the concrete affect the bond strength of concrete. The addition of mineral admixtures like fly ash, silica fume, rice husk ash etc. into the cement by means of replacing the cement content is nowadays considering as an important matter for protecting the environment against any hazardous situations and also recycling the waste by-products into an effective manner. But, the addition of mineral admixtures affects the structural system of cement and also in concrete. It also leads to the variations in the properties of concrete both fresh and hardened state. With these in mind, the bond strength variations of ternary blended concrete were examined in this experimental investigation and compared with the normal strength concrete. The class F type Fly Ash (FA) was used for making the binary blended concrete. In addition to that Silica Fume (SF) and Rice Husk Ash were (RHA) considered for developing the ternary blended concrete.

 Abstract

The performance of pavement is very responsive to the characteristics of the flyash subgrade. For that reason, weak subgrade is enhanced by adopting the most efficient stabilization technique. Based on the literature review, stabilization with crusher dust activated with cement was found to be an effective option for improvement of flyash properties. In this regard an experimental program was undertaken to study the effect caused by the combined action of crusher dust and cement stabilization on the geotechnical characteristics of weak subgrade flyash. Flyash treated with varying percentages of crusher dust, 0, 5, 10, 15, and 20 percent combined with 5% cement content were studied. Consistency limits, compaction, California Bearing Ratio and permeability tests were conducted on treated and untreated flyash. The experimental results show that addition of cement crusher dust admixture to the flyash has great influence on its properties. It was found that the optimum dosage of crusher dust is 25% mixed with 5% cement revealed in significant improvement in strength and durability and reduction in permeability and liquid limit properties of the flyash. Based on the results, it is recommended that cement-crusher dust admixture be considered a viable option for the stabilization of subgrade.

Abstract: Present study is an approach to socio economic and domestic consumptions, especially concentration on selected slums in greater Visakhapatnam city of Andhra Pradesh state. Slums are an urban phenomenon which comes into existence on account of industrialization in and around cities thereby attracting in migration of population from country side. Though slums are a rich source of un-skilled and semi-skilled manpower, they tend to result in burden on the existing civic amenities. India's urbanization is often termed as over urbanization, pseudo- urbanization. The big cities attained inordinately large population size leading to virtual collapse in the urban services and followed by basic problems in the field of housing, slum, water, infrastructure, quality of life etc. Slum dwellers often lack adequate access to clean water and sanitation facilities. Water supplies may be unreliable, expensive or contaminated.. The lack of adequate sanitation in slums results in the pollution of groundwater, water sources and coastlines. The environmental impact of poor sanitation in unplanned urban settlements may be hidden in statistics that consider access to improved sanitation.

 Abstract

The developing reliance of clients via web-based networking media, media transmission administrations, portable applications and other cloud services requires an arrangement that mitigates inescapable failures and guarantees the dependably on access to these services. So there must be a way to handle these failures during migration and adoption of cloud without any redundancy. This paper proposes migration way to deal with managing benefit conveyance upon a sudden failure, a virtual machine (VM) over-burden, or support. It builds up a combined redundancy handling FTC programming model that limits the movement downtime that is based on VM memory pages and the reliable situation of the VM. Experimental results shows that proposed system is much reliable than existing systems. The results are calculated in terms of make span, energy consumption and fault tolerance rate during VM migration resource allocation.
