The growing demand for quality and performance has become a discriminating factor in the field of web applications. Advances in software technology and project management have increased the amount of web applications which are developed under these aspects. At the same time the research in web performance simulation and prediction is focusing on complex modeling methods and techniques rather than...
The frequent and volatile unavailability of volunteer-based grid computing resources challenges grid schedulers to make effective application placements. The manner in which host resources become unavailable will have different effects on different applications, depending on their runtime and their ability to be checkpointed or replicated. A multi-state availability model can help improve scheduling...
In this paper the problem of prediction of queue lengths in the multi-queue-single-processor queuing system is considered. Efficient solutions for this problem are crucial in many technical appliances, such as load balancing in multi-processor systems. Here, a fuzzy-neural model for approximation of the average future system load along with model identification algorithm are proposed. Moreover, condition...
