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.
