It is a simple method to determine the production of Torque in Repulsion motor based on the
basic Theory of magnetism. The Torque Characteristics of the motor is developed by shifting the brushes
position of Repulsion motor. In this case – desires to shifting the angle of brushes, to study, how the torque will
be developed with concept of the Theory of the magnetism and also to explain torque characteristic of the
Repulsion motor as developed for various position of brush shifts corresponds to the practical curve of the said
motor. The Torque Characteristics can successfully determine and as well as its performance.
KEYWORDS: Torque, analytical aspects of Torque production, Geometrical analysis of Torque.

Around the world, applications of information and communications technologies (ICT) are making dramatic changes in economic and social development. These changes go beyond a mere increase in the number of computers appearing in work places, homes, and schools to more fundamental changes in the foundations of economic growth and its relationship to human capital. These tectonic economic and social changes have been characterized by terms such as "knowledge economy" and "learning society", conveying the notion that knowledge and learning are now at the core of economic productivity and social development. Research work and experience in using media, methods, curricular articulations, and learning environments in an innovative manner, stimulated studies and characterization of factors involved in improving educational practice related to the use of ICT, with special attention to the culture of diversity, as well as those elements that enhance or inhibit their generalization.

In this paper we consider the problem of finding the number of zeros of a polynomial in a given
circle when the coefficients of the polynomial or their real or imaginary parts are restricted to certain
conditions. Our results in this direction generalize some known results in the theory of the distribution of zeros
of polynomials.

We explore the problem of the Falkner-Skan boundary layer flow past a wedge considering the velocity slip condition and nanofluid. The governing partial differential equation is transformed into an ordinary differential equation. The numerical results of the resulting ordinary system are obtained using Matlab software. The effect of the slip parameter on the flow and the presence of the nanofluids are discussed.

There are a number of quality model already available like MC.Call Quality model, Boehm Quality model, ISO 9126, Capability maturity model and LISA(Localisation Industry standard association ) has also introduced its own QA model. Each model is adapted by several organizations in some way to manage the quality assurance process for the components in the product. The purpose of this paper is to simulate some of the already existing QA models with regard to the localized product and to introduce a new Generalized QA model combining the advantages of several. It also discusses the QA model with an example of the tester module named GUNVATTA PARIKSHAK and identifies the value metric for each of the operation.

Web application today are become more rich and complex. For building such application developers are using Ajax and Web 2.0 technologies. This powerful technologies offer advanced features for building user-friendly and highly interactive web applications that are providing quality end-user experience. Deploying web application is a challenge both in assuring that the functionality will be maintained and in guaranteeing that the functionality will be delivered with an acceptable performance. Performance problems can bring all kind of undesired consequences. For web applications especially in an e-commerce situation, performance testing is crucial. Performance testing is a type of testing that is performed, from one perspective, to determine how fast some abstract of a system performs under a particular workload. In this paper we discuss general concepts, practices and tools that lie at the core of performance testing web applications. Performance analysis tools from the open-source can be used to achieve effective web application performance tests. A case study will be given to demonstrate these tools used in a Ajax web application. In this paper we conclude that performance tools helps software developer to find out bottleneck in performance of the system as well as to choose a good platform for designing web application.

Cloud computing is a Service Oriented Architecture which reduced information technology overhead for the end-user and provide great flexibility, reduced total cost of ownership, on-demand services and many other things [1]. Hence it delivered all IT related capability as services rather than product .Services on cloud are divided into three broad categories: Software as a Service, Infrastructure as a Service & Platform as a Service. Same as services cloud is also classified as Private Cloud, Public Cloud & Hybrid Cloud. Private cloud is increasingly become popular between every private organization either large or small wants .To deploy public or private cloud there are many open source software available some are Eucalyptus, Nimbus, OpenStack, Open Nebula Cloud stack and Amazon Web Services .This paper, I provide a study of the main open source software such as Eucalyptus, OpenStack and OpenNebula for cloud implementation. It is believe that the comparison presented in this paper would benefit developers in selecting best open source Software.

In Wireless Sensor Networks(WSN) data transmission is one the major challenges and a number of routing protocols have been proposed to cope up with this problem by saving energy during transmission. Routing protocols that performs in-network aggregation are best suited for this purpose to yield energy saving Data Transmission. In this paper we are proposing an improved version of M-SPIN protocol named "I-SPIN" protocol. Our protocol aims at disseminating data to the sink node through shortest path in such a way that the load is uniformly distributed among all the nodes lying in the path and hence the probability of the nodes of being dead is almost same. Thus we don‟t have to calculate the shortest path as frequently as in M-SPIN protocol and all the sensor nodes in the network are utilized almost equally. Also I-SPIN protocol is more reliable than M-SPIN because the decay time of the sensor nodes is increased.

The main objective of our project is to design a 32 bit Arithmetic Logic Unit which is a digital circuit that performs arithmetic and logical operations using VHDL. The ALU is a fundamental building block of the central processing unit (CPU) of a computer, and even the simplest microprocessors contain one for purposes such as maintaining timers. The processors found inside modern CPUs and graphics processing units (GPUs) accommodate very powerful and very complex ALUs; a single component may contain a number of ALUs. This behavioral design can be made synthesizable and thus can be used for layout and fabrication on FPGA based digital circuits.
