Van der Waals Heterojunctions for Emerging Device Applications
Low-dimensional systems are an exciting platform for exploring new physics and realizing novel devices. The intriguing features, such as the existence of strongly bound multiparticle complexes and thickness-dependent band ... -
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, ... -
Verification of information flow properties
Information flow properties are a way of specifying security properties of systems, that dates back to the work of Goguen and Meseguer [7] in the eighties. A system is viewed as generating traces containing “confidential” ... -
Vision-driven Tele-Operation for Robot Manipulation
It’s worth the time to acknowledge just how amazingly well we humans can perform tasks with our hands. Starting from picking up a coin to buttoning up our shirts. All these tasks for robots are still at the very forefront ... -
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 ... -
VLSI architecture for the parallel computation of power system problems.
The large size and modeling complexities of power system problems have been providing the motivation for the use of fast computers and the search for new algorithms. The present trend of using digital computers for the ... -
Voltage Stability Analysis of Unbalanced Power Systems
(2018-02-07)The modern day power system is witnessing a tremendous change. There has been a rapid rise in the distributed generation, along with this the deregulation has resulted in a more complex system. The power demand is on a ... -
Wave from mapped multiplexing: an alternative methodology for multiplexing plesiochronous channels.
From the above analysis, it is evident that implementing Weighted Mean Method (WMM) using a fixed point of reconstruction introduces a bias of the form (x?Tg2)Tg2(x - \frac{T_g}{2})^{\frac{T_g}{2}}(x?2Tg??)2Tg?? in the ... -
Wavelength routing in All-Optical networks using full, limited and no wavelength conversion
We study the effect of full, limited and no wavelength conversion on the blocking performance of the all-optical networks. We first formulate an exact model for linear tree networks for the case of full and no wavelength ... -
Wavelet array transform for signal representation using generalised hermite polynomials
The thesis deals with a framework for the analysis and synthesis of one- and two-dimensional signals, created by a new array of wavelets as basis functions, which are derived from generalized Hermite polynomials. The ... -
Wavelet Based Algorithms For Spike Detection In Micro Electrode Array Recordings
(2010-07-13)In this work, the problem of detecting neuronal spikes or action potentials (AP) in noisy recordings from a Microelectrode Array (MEA) is investigated. In particular, the spike detection algorithms should be less complex ... -
Wavelets for volume graphics
In recent years, there has been a shift in the paradigm from surface-based graphics to volume graphics. Volume graphics uses a three-dimensional unit cube, known as a voxel, as its primitive, whereas surface-based graphics ... -
Weak visibility and related problems on simple polygons
Visibility and shortest path problems are two important areas of research in computational geometry. In this thesis we study weak visibility and related problems on simple polygons and propose efficient algorithms. We study ...
