The original design for the PCI bus was to move high bandwidth peripherals closer to the CPU for performance gains. Graphics-oriented operating systems (OS) and other high bandwidth functions such as Ultra2 SCSI, Fibre Channel, Fast Ethernet, and 3D graphics are consuming more PCI bus bandwidth. This need for more bandwidth has compelled system vendors to(More)
Invisible persons are seen in fiction stories only, but in the real world it is proved that invisibility is possible. This paper describes the creation of invisibility with the help of technologies like Optical camouflage; Image based rendering and Retro-reflective projection. The object that needs to be made transparent or invisible is painted or covered(More)
Image compression is one of the prominent signal processing areas for multimedia applications. Compressed images when transmitted are affected by noise and thus reconstruction of images at the receiver becomes complex. Very recently Artificial Neural Networks are being used for image compression and decompression. One of the building blocks in ANN is the(More)
Flexible ac Transmission Systems (FACTS) devices are used to control power flow in the transmission grid to relieve congestion and limit loop flows. High cost and reliability concerns have limited the widespread deployment of FACTS solutions. The present paper describes the steady-state response and control of power in Transmission line equipped with FACTS(More)
Power dissipation of a VLSI chip was not a concern in the past. A lot of effort has been put into synthesis for speed and area, power optimization has been explored only recently. Since power estimation is the foremost step in any low power design; this work concentrates on developing a technique that estimates the toggle rates for circuits implemented on a(More)
The present paper describes the modeling of Distributed Power Flow Controllers (DPFC) for studying the steady-state response and behavior of Transmission networks equipped with FACTS devices. Detailed simulations are carried out on two-machine systems to illustrate the control features of these devices and their influence to increase power transfer(More)
A synchronous counter, in contrast to an asynchronous counter, is one whose output bits change state simultaneously, with no ripple. A simple way of implementing the logic for each bit of an ascending counter is for each bit to toggle when all of the least significant bits are at a logic high state. In this paper we aim for the timing driven placement and(More)
