Supervised Learning of Piecewise Linear Models
(2018-03-07)
Supervised learning of piecewise linear models is a well studied problem in machine learning community. The key idea in piecewise linear modeling is to properly partition the input space and learn a linear model for every ...
A Networked Control Systems Framework for Smart Grids with Integrated Communication
(2018-02-28)
Over the last decade, power systems have evolved dramatically around the world, owing to higher demand, stringent requirements on quality and environmental concerns that are becoming increasingly critical. With the ...
Study on Pulsewidth Modulation Techniques for a Neutral-Point-Clamped Voltage Source Inverter
(2018-02-23)
Neutral-point-clamped (NPC) three-level inverter is capable of handling higher dc bus voltage and producing output waveform of better quality than a conventional two-level inverter. The main objective of the present work ...
Frequency and Time Domain Response Analysis of Transformer Winding for Indirect Measurement of Series Capacitance and Construction of Ladder Network Models
(2018-02-10)
This thesis proposes innovative methods to extract information embedded in the frequency and time domain response of the transformer winding, and utilizes them to suggest solutions to a few tasks that have until now been ...
Adaptive Sampling Pattern Design Methods for MR Imaging
(2018-02-07)
MRI is a very useful imaging modality in medical imaging for both diagnostic as well as functional studies. It provides excellent soft tissue contrast in several diagnostic studies. It is widely used to study the functional ...
PWM Techniques for Split-Phase Induction Motor Drive
(2018-02-18)
A split-phase induction motor (SPIM) is obtained by splitting each of the three-phase stator windings of an induction motor into two equal halves. This results in two sets of three-phase windings with a spatial angle ...
Control, Modulation and Testing of High-Power Pulse Width Modulated Converters
(2018-04-02)
Experimental research on high-power converters, particularly in an academic environment, faces severe infrastructural constraints. Usually, power source and loads of required ratings are not available. Further, more ...
Sub-Nyquist Sampling and Super-Resolution Imaging
(2018-07-04)
The Shannon sampling framework is widely used for discrete representation of analog bandlimited signals, starting from samples taken at the Nyquist rate. In many practical applications, signals are not bandlimited. In order ...
Design and Analysis of Real-time Message Scheduling under FlexRay Protocol
(2018-05-29)
A typical automobile system consists of many Electronic Control Units (ECUs) for the purposes of safety, comfort, and entertainment applications. FlexRay is a high bandwidth protocol for such automotive requirements, which ...
Low Switching Frequency Pulse Width Modulation for Induction Motor Drives
(2018-06-11)
Induction motor (IM) drives are employed in a wide range of industries due to low maintenance, improved efficiency and low emissions. Industrial installations of high-power IM drives rated up to 30 MW have been reported. ...
