Some years ago the supercomputer landscape changed dramatically: the supremacy of vector processorbased systems had to give way to machines built from Commodity Of-The-Shelf (COTS) products that promised to deliver a better price-performance ratio. In addition cheap Beowulf clusters emerged and are massively employed in laboratories all over the world. We discuss some reasons for this change an...

An Unified Power Flow Controller (UPFC) is a typical Flexible AC Transmission System (FACTS) device playing a vital role as a stability aid for large transient disturbances in an interconnected power system.This paper deals with the design of Feedback Linearising Controller (FBLC) for UPFC.The disturbances are created in the SMIB system and the results are simulated.The results proved the supre...

Owing to the technological advancement in communication areas, presently, the security and the reliability of operating power system is very much possible on real-time platform. Phasor measurement units (PMUs) are based on these advance communication technology and are one of the most important equipment for electric utility, now a days, helpful in maintaining a healthy operating power system. ...

Preventing denial-of-service attacks in wireless sensor networks is difficult primarily because of the limited resources available to network nodes and the ease with which attacks are perpetrated. Rather than jeopardize design requirements which call for simple, inexpensive, mass-producible devices, we propose a coping strategy that detects and maps jammed regions. We describe a mapping protoco...
