ABSTRACTRenewable Energy Sources (RES) are well – defined as energy sources, that are in abundance within the natural surroundings and are much inexhaustible. In addition, hydroelectricity (HE) is a vital part of world renewable energy supply and hydropower remains a bulk source of electricity generation because of its environmental friendliness in nature. Modeling is the analysis of the ...
This paper presents a new system, called NetSolve, that allows users to access computational resources, such as hardware and software, distributed across the network. The development of NetSolve was motivated by the need for an easy-to-use, efficient mechanism for using computational resources remotely. Ease of use is obtained as a result of different interfaces, some of which require no progra...
With the rapid development of Internet, Grid becomes more and more popular. In this paper, mobile service is introduced to solve some key problems in Grid environment, such as load balance and fault tolerance etc. A mobile service is the combination of Grid service and mobile agent and has migration ability that can make it migrate between grids and ability to detect surroundings to decide when...
The ability to decompose a complex, long-running query into simpler queries that produce the same result is useful for many scenarios, such as admission control, resource management, fault tolerance, and load balancing. In this paper we propose query slicing as a novel mechanism to do such decomposition. We study different ways to extend a traditional query optimizer to enable query slicing and...
Load Testing helps to capture performance at different load levels. It is naïve to assume that application performance at a certain load level may be in the same band that the load testing has pointed out. By introducing small spike for short duration we observed that applications either show resiliency, graceful degradation and recovery or total crash even after the spike has subsided. This be...

In recent years, several frameworks have been developed for processing very large quantities of data on large clusters of commodity PCs. These frameworks have focused on fault-tolerance and scalability. However, when using heterogeneous environments these systems do not offer optimal workload balancing. In this paper we present Jumbo, a distributed computation platform designed to explore possi...
As software systems evolve over a series of releases, it becomes important to know which components are stable compared to components that show repeated need for corrective maintenance. The latter is a sign of code decay. Code decay can be due to the deterioration of a single component. In this case it manifests itself in repeated and increasing problems that are local to the component. A secon...
Load sharing can improve performance in distributed systems by transferring work from heavily loaded nodes to lightly loaded nodes. We propose a lter component to be included in a load sharing algorithm to detect short-lived jobs not worth considering for remote execution. One lter, called History, detects short-lived jobs by using job names and statistics based on previous executions. Job trac...
In this paper, methods of fault location are discussed in electrical traction single-end direct power supply network systems. Based on the distributed parameter model of the system, the position of the short-circuit fault can be located with the aid of the current and voltage value at the measurement end of the electrical traction line. Furthermore, the influence of the transient resistance, th...
