Jobs to be processed in distributed systems are often characterized by a high complexity. Several interdependent tasks (here called "steps") have to be performed on possibly different sites using different types of resources (services) [1,2,5-7]. As an example, think of a print job (job type J1) submitted by a user to be printed on some special printer. This print job consists of a database acc...

The recent dramatic improvements in the performance of commodity hardware has made clusters of workstations or PCs an attractive and economical platform upon which to build scalable database servers. These clusters have large aggregate memory capacities; however, since this global memory is distributed, good algorithms are necessary for memory management, or this large aggregate memory will go ...

The dayahead short term load forecasting (STLF) is a necessary daily task for power dispatch. Short term load forecasting is essential for unit commitment, economic allocation of generation, maintenance schedules. This paper presents a solution methodology using fuzzy logic for short term load forecasting. Fuzzy logic approach is implemented on weather sensitive data and historical load data fo...

Microturbine generation system is one of the most promising and a fast growing distributed generation sources. It is used in various applications thanks to high efficiency, quick start and high reliability. Combination of the microturbine and storage system (e.g. battery bank) is desirable selection to satisfy the load requirements under all conditions and hence the battery bank can play an imp...
