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...

The color of the gingiva has a tremendous impact on the esthetics of the smile. Clinically gingival melanin hyper pigmentation is presented as ‘black gum’ which is a common esthetic problem especially for those who have gummy smile. Several attempts have been made for removal of gingival pigmentation by different techniques. Each technique had its own supremacy in efficiency and also draw back....

Hindu medicine correctly judged by him is a composite system. It consists of a Dravidian system on which was superimposed an Aryan system on which in its turn was superimposed a Buddhist system. The Dravidian system centres round Dhanvantari who does not figure in the vedic pantheon of the Aryan immigrants. He is one of the 14 jewels churned out of the milky ocean at the beginning of time when ...

Many prominent jurists and scholars, including those with outlooks as diverse as Chief Justice John Roberts and Cass Sunstein, have recently advocated a “minimalist” approach to opinion writing at the Supreme Court. They assert that the Court should issue narrow, fact-bound decisions that do not resolve much beyond the case before it. I argue that minimalism, as employed by the current Supreme ...
