 Abstract— Wavelet Transform is a time-frequency representation of the input signal. Realization of wavelet transform on field-programmable gate array (FPGA) device for the detection of power system disturbances is proposed in this thesis. This approach provides an integral signal-processing paradigm, where its embedded wavelet basis serves as a window(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 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)
The Euler-Bernoulli's method is used to model the dynamics of single link flexible manipulator. Model is highly nonlinear in nature, consists of partial differential equations, and so with the help of MATLAB & SIMULINK is taken. The state space model is designed by using S function block in SIMULINK and it's M-file in MATLAB. The response of the model is(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)
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)
Recently several papers have appeared in the literature which propose pseudo-dynamic features for automatic static handwritten signature verification based on the use of gray level values from signature stroke pixels. Good results have been obtained using rotation invariant uniform local binary patterns LBP plus LBP and statistical measures from gray level(More)
