Direct Time Domain Modelling Of First Return Stroke Of Lightning
(2009-05-21)Being one of the most spectacular events in nature, lightning is basically a transient high current electric discharge in the atmosphere, which extends up to kilometres. Cloud to ground discharge is the most hazardous one ... -
Modeling, Analysis And Control Of Single-Phase And Three-Phase PWM Rectifiers
(2009-06-16)Pulse width modulation (PWM) rectifiers are extensively used in battery charger, regulated dc voltage source, UPS systems, ac line conditioner and motor drives. The conventional control schemes for these rectifiers require ... -
Music And Speech Analysis Using The 'Bach' Scale Filter-Bank
(2009-08-13)The aim of this thesis is to define a perceptual scale for the ‘Time-Frequency’ analysis of music signals. The equal tempered ‘Bach ’ scale is a suitable scale, since it covers most of the genres of music and the error is ... -
A New Family Of Soft Transition DC-DC Converters
(2009-09-10)Switched mode power supplies (SMPS) have found wide spread acceptance in all power processing applications. The design demand is moving towards higher power densities. For reduction in size and weight, it is imperative to ... -
A Peer To Peer Web Proxy Cache For Enterprise Networks
(2009-09-10)In this thesis, we propose a decentralized peer-to-peer (P2P) Web proxy cache for enterprise networks (ENs). Currently, enterprises use a centralized proxy-based Web cache, where a dedicated proxy server does the caching. ... -
Perceptual Criterion Based Rate Control And Fast Mode Search For Spatial Intra Prediction In Video Coding
(2010-03-11)This thesis dwells on two important problems in the field of video coding; namely rate control and spatial domain intra prediction. While the former is applicable generally to most video compression standards, the latter ... -
