Generation Of 12-Sided And 18-Sided Polygonal Voltage Space Vectors For Inverter Fed Induction Motor Drives By Cascading Conventional Two-Level Inverters
(2010-06-01)Multi-level inverters play a significant role in high power drive systems for induction motors. Interest in multi-level inverters started with the three-level, neutral point clamped (NPC) inverter. Now there are many ... -
Compiler-Assisted Energy Optimization For Clustered VLIW Processors
(2010-04-13)Clustered architecture processors are preferred for embedded systems because centralized register file architectures scale poorly in terms of clock rate, chip area, and power consumption. Although clustering helps by ... -
Battery Buffered Stiff Micro Grid Structure For A Variable Speed Slip Ring Induction Machine Based Wind Generation System
(2010-04-12)Electric power has become a basic necessity of human life. The major share of electric power comes from fossil fuel which results in global warming and pollution. A share of generated power comes from nuclear power which ... -
Impact Of Energy Quantization On Single Electron Transistor Devices And Circuits
(2010-04-06)Although scalingof CMOS technology has been predicted to continue for another decade, novel technological solutions are required to overcome the fundamental limitations of the decananometer MOS transistors. Single Electron ... -
Semi-Supervised Classification Using Gaussian Processes
(2010-03-26)Gaussian Processes (GPs) are promising Bayesian methods for classification and regression problems. They have also been used for semi-supervised classification tasks. In this thesis, we propose new algorithms for solving ... -
Signal Processing Algorithms For Digital Image Forensics
(2010-03-19)Availability of digital cameras in various forms and user-friendly image editing softwares has enabled people to create and manipulate digital images easily. While image editing can be used for enhancing the quality of the ... -
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 ... -
Towards Achieving Better NOx Removal In Discharge Plasma Treatment Of Diesel Engine Exhaust
(2010-03-03)In India, the expansion of industries and two-fold increase in motor vehicles over the last decade are posing a serious environmental crisis in the form of urban air pollution. Common pollutants include carbon monoxide, ... -
Errors In Delay Differentiation In Statistical Multiplexing
(2010-03-03)Different applications of communication networks have different requirements that depend on the type of application. We consider the problem of differentiating between delay-sensitive applications based on their average ... -
Time Management In Partitioned Systems
(2010-02-11)Time management is one of the critical modules of safety-critical systems. Applications need strong assurance from the operating system that their hard real-time requirements are met. Partitioned system has recently evolved ... -
Linear Network Coding For Wireline And Wireless Networks
(2010-02-10)Network Coding is a technique which looks beyond traditional store-and-forward approach followed by routers and switches in communication networks, and as an extension introduces maps termed as ‘local encoding kernels’ and ... -
FIR System Identification Using Higher Order Cumulants -A Generalized Approach
(Indian Institute of Science, 2010-01-12)The thesis presents algorithms based on a linear algebraic solution for the identification of the parameters of the FIR system using only higher order statistics when only the output of the system corrupted by additive ... -
Joint Evaluation Of Multiple Speech Patterns For Speech Recognition And Training
(2009-12-09)Improving speech recognition performance in the presence of noise and interference continues to be a challenging problem. Automatic Speech Recognition (ASR) systems work well when the test and training conditions match. ... -
Receiver Channelizer For FBWA System Confirming To WiMAX Standard
(2009-09-10)Fixed Broadband Wireless Access (FBWA) is a technology aimed at providing high-speed wireless Internet access, over a wide area, from devices such as personal computers and laptops. FBWA channels are defined in the range ... -
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
