Variability Aware Device Modeling and Circuit Design in 45nm Analog CMOS Technology
(2018-05-10)Process variability is a major challenge for the design of nano scale MOSFETs due to fundamental physical limits as well as process control limitations. As the size of the devices is scales down to improve performance, the ... -
Variants and Generalization of Some Classical Problems in Combinatorial Geometry
(2018-02-18)In this thesis we consider extensions and generalizations of some classical problems in Combinatorial Geometry. Our work is an offshoot of four classical problems in Combinatorial Geometry. A fundamental assumption in these ... -
Variants of Hegselmann-Krause Model
(2017-12-04)The Hegselmann-Krause system (HK system for short) is one of the most popular models for the dynamics of opinion formation in multi agent systems. Agents are modeled as points in opinion space, and at every time step, each ... -
Variational Bayes Algorithms for mmWave and Massive MIMO-OFDM Systems with Low Resolution ADCs
In this thesis, we develop novel low-complexity algorithms for massive multiple-input multiple-output (MIMO) systems under practical non-idealities and theoretically analyze their performance. The first problem we consider ... -
Verification of a Generative Separation Kernel
A Separation Kernel is a small specialized microkernel that provides a sand-boxed execution environment for a given set of processes (also called \subjects"). The subjects may communicate only via declared memory channels, ... -
Visual Analysis Of Interactions In Multifield Scientific Data
(2014-11-14)Data from present day scientific simulations and observations of physical processes often consist of multiple scalar fields. It is important to study the interactions between the fields to understand the underlying phenomena. ... -
Visual Speech Recognition
Visual speech recognition (VSR), or automatic lip-reading, is the task of extracting speech information from visual input. The addition of visual speech has been shown to improve the performance of traditional audio ... -
Voltage Stability Analysis of Unbalanced Power Systems

(2016-07-12)Wireless Sensor Networks (WSNs) consist of a large number of resource constrained sensor nodes equipped with various sensing devices which can monitor events in the real world. There are various applications such as ... -
Who Spoke What And Where? A Latent Variable Framework For Acoustic Scene Analysis
(2016-09-15)Speech is by far the most natural form of communication between human beings. It is intuitive, expressive and contains information at several cognitive levels. We as humans, are perceptive to several of these cognitive ... -
Why only two ears? Some indicators from the study of source separation using two sensors
(Indian Institute of Science, 2005-02-10)In this thesis we develop algorithms for estimating broadband source signals from a mixture using only two sensors. This is motivated by what is known in the literature as cocktail party effect, the ability of human beings ... -
