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. ... -
Interference Cancelling Detectors In OFDMA/MIMO/Cooperative Communications
(2009-09-02)In this thesis, we focus on interference cancelling (IC) detectors for advanced communication systems. The contents of this thesis is divided into the following four parts: 1. Multiuser interference (MUI) cancellation in ... -
Energy Efficient Scheduling Of Sensing Activity In Wireless Sensor Networks Using Information Coverage
(2009-08-19)Network lifetime is a key issue in wireless sensor networks where sensor nodes, distributed typically in remote/hostile sensing areas, are powered by finite energy batteries which are not easily replaced/recharged. Depletion ... -
Blind Detection Techniques For Spread Spectrum Audio Watermarking
(2009-08-13)In spreads pectrum (SS)watermarking of audio signals, since the watermark acts as an additive noise to the host audio signal, the most important challenge is to maintain perceptual transparency. Human perception is a very ... -
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 ... -
Low Correlation Sequences Over AM-PSK And QAM Constellations
(2009-08-13)Direct-Sequence Code Division Multiple Access (DS-CDMA), over the last few years, has become a popular technique and finds a place in many modern communication systems. The performance of this technique is closely linked ... -
Soft Switched Multi-Phase Tapped-Boost Converter And Its Control
(2009-08-04)Boost dc-to-dc converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the ... -
Design Of 1400W Telecom Power Supply With Wide Range Input AC Voltage
(2009-07-24)In the fast growing field of Telecommunications, the back up DC power supply plays a vital role in powering the telecom equipment. This DC power supply is a combination of AC-DC Rectifier coupled with a battery bank to ... -
Optimizations In Storage Area Networks And Direct Attached Storage
(2009-07-23)The thesis consists of three parts. In the first part, we introduce the notion of device-cache-aware schedulers. Modern disk subsystems have many megabytes of memory for various purposes such as prefetching and caching. ... -
Robust Techniques Of Language Modeling For Spoken Language Identification
(2009-07-23)Language Identification (LID) is the task of automatically identifying the language of speech signal uttered by an unknown speaker. An N language LID task is to classify an input speech utterance, spoken by an unknown ... -
Development Of Algorithms For Security Oriented Power System Operation
(2009-07-23)The objective of an Energy Control Center (ECC) is to ensure secure and economic operation of power system. The challenge to optimize power system operation, while maintaining system security and quality of power supply ... -
Power System Data Compression For Archiving
(2009-07-23)Advances in electronics, computer and information technology are fueling major changes in the area of power systems instrumentations. More and more microprocessor based digital instruments are replacing older type of meters. ... -
Design Of Linear Precoded MIMO Communication Systems
(2009-07-09)This work deals with the design of MT transmit, MR receive antenna MIMO (Multiple Input Multiple Output) communication system where the transmitter performs a linear operation on data. This linear precoding model includes ... -
A Mechanism Design Approach To Resource Procurement In Computational Grids With Rational Resource Providers
(2009-07-08)A computational grid is a hardware and software infrastructure that provides dependable, consistent, pervasive, and inexpensive access to high-end computational capabilities. In the presence of grid users who are autonomous, ... -
Superscalar Processor Models Using Statistical Learning
(2009-06-24)Processor architectures are becoming increasingly complex and hence architects have to evaluate a large design space consisting of several parameters, each with a number of potential settings. In order to assist in guiding ... -
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 ... -
Efficient Online Path Profiling
(2009-06-05)Most dynamic program analysis techniques such as profile-driven compiler optimizations, software testing and runtime property checking infer program properties by profiling one or more executions of a program. Unfortunately, ... -
