Integrated CM Filter for Single-Phase and Three-Phase PWM Rectifiers
(2018-08-11)
The use of insulated-gate bipolar transistor (IGBT)-based power converters is increasing exponentially. This is due to high performance of these devices in terms of efficiency and switching speed. However, due to the ...
Efficient Transceiver Techniques for Massive MIMO and Large-Scale GSM-MIMO Systems
(2018-08-13)
Multi-antenna wireless communication systems that employ a large number of antennas have recently stirred a lot of research interest. This is mainly due to the possibility of achieving very high spectral efficiency, power ...
Experimental Studies on Acoustic Noise Emitted by Induction Motor Drives Operated with Different Pulse-Width Modulation Schemes
(2018-08-13)
Voltage source inverter (VSI) fed induction motors are increasingly used in industrial and transportation applications as variable speed drives. However, VSIs generate non-sinusoidal voltages and hence result in harmonic ...
Design, Fabrication and Characterization of Low Voltage Capacitive RF MEMS Switches
(2018-08-11)
This dissertation presents the design, fabrication, and characterization of low-voltage capacitive RF MEMS switches. Although, RF MEMS switches have shown superior performance as compared to the existing solid-state ...
Approximate Dynamic Programming and Reinforcement Learning - Algorithms, Analysis and an Application
(2018-08-13)
Problems involving optimal sequential making in uncertain dynamic systems arise in domains such as engineering, science and economics. Such problems can often be cast in the framework of Markov Decision Process (MDP). ...
Resource Allocation in Femtocells via Game Theory
(2018-08-14)
Most of the cellular tra c (voice and data) is generated indoors. Due to attenuation from walls, quality of service (QoS) of di erent applications degrades for indoor tra c. Thus in order to provide QoS for such users the ...
Lightning Shielding Failure Analysis of Ultra High Voltage Power Transmission Lines
(2018-08-14)
In India, the natural energy resources (thermal and hydro) are unevenly distributed and are mostly present in the remote areas and the load centers are distributed across various regions of the country. Therefore high ...
On a Divide-and-Conquer Approach for Sensor Network Localization
(2018-08-20)
Advancement of micro-electro-mechanics and wireless communication have proliferated the deployment of large-scale wireless sensor networks. Due to cost, size and power constraints, at most a few sensor nodes can be equipped ...
Studies on Silicone Rubber Insulators used for High Voltage Transmission
(2018-08-20)
Recently high temperature vulcanized (HTV) silicone rubber (SIR) / polymeric/composite insulators are gaining wider acceptance as overhead transmission line insulators for extra high voltage (EHV) and ultra-high voltage ...
Active Power Flow Tracing for Preventive Control in Deregulated Power Systems
(2018-05-29)
Modern day power systems present an open access environment, inspiring participation from small scale and large power suppliers. With multiple players in the system driven by the market, proper monitoring and control of ...
