Abstract: Grid Computing is a form of distributed Computing that has emerged as a viable solution to meet the ever increasing needs for computational power and data management capability. Designing solutions in such grid computing framework entails addressing much more complicated issues compared to chore software development, namely concurrency, heterogeneity, scalability and so forth; just to name a few. In order to simplify the task of programming in grid environment a software layer is employed to mask off the massive underlying heterogeneity in network, hardware, operating system and programming languages, known as the middleware. Moreover, resources in a grid are dynamic and thus incorporating appropriate scheduling mechanism becomes a challenging proposition. This paper addresses some major issues in context of job scheduling in computational grids: namely, average active jobs, busy time of CPU, heap memory and average CPU load. They are treated as Work Load Description (WLD) in a grid sc

Abstract: Process control and energy conservation are the two primary reasons for using an adjustable speed drive (ASD). However, voltage sags are the most important power quality problem facing many commercial and industrial customers. Voltage sag problem arise because of transients in supply voltage by the usage of heavy inductive loads. Therefore to improve the performance and reliability of the motor and drive, new controlling drives has to be implemented with the help of power electronics. Adjustable Speed Drives (ASD) is the emerging trend in the induction motor research to improve the performance during voltage sag conditions. The ride-through capability of the induction motor during voltage sag is taken into account that duration of the ride-through operation depends on the initial motor flux, speed level, rotor time constant, load torque and inertia. Also Inverter design mainly affects the motor performance. A new combination technique has been proposed for the mitigation of voltage sag
