No/Nox Removal In Diesel Engine Exhaust Under Different Energizations And Reactor Configurations
(2010-06-09)In India, with the increase in the number of industries and vehicles the environment is getting more and more polluted. More than industries it is the rapid growth of vehicles which causes serious environmental crisis in ... -
A Novel Higher Order Noise Shaping Sigma-Delta Modulator
(2010-06-04)The thesis focuses on a higher order noise-shaping Δ ADC architecture which employs filtered quantization error as a dither signal. Furthermore, the work studies implementation challenges using Switched-Capacitor and ... -
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ... -
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 ... -
