Adjacent Independent Row (Air) Matrices and Index Coding
An index coding problem, comprises a transmitter that has a set of independent messages and a set of receivers. Each receiver knows a subset of messages, called its side-information, and demands another subset of messages, ... -
Contributions on Index Coding, Coded Caching and Gradient Coding
In this thesis, we cover three major areas, namely, index coding, coded caching and gradient coding. We begin by considering unicast index coding problems where a server broadcasts coded messages over a noiseless channel, ... -
Energy-Efficient Data Fusion Techniques for Wireless Sensor Networks
Wireless sensor networks (WSNs) are finding increasing use in applications such as environmental monitoring, military surveillance, and healthcare due to their low cost and ease of deployment. However, the nodes in a ... -
Engineering quantum emitters in WSe2 films on metal films
The discovery of single photon emitters (SPEs) in van der Waals materials, in particular, from point defects in Tungsten Diselenide (WSe2) and hexagonal Boron Nitride (hBN), has sparked tremendous research interest in the ... -
Linear Dynamical Systems with Sparsity Constraints: Theory and Algorithms
This thesis develops new mathematical theory and presents novel recovery algorithms for discrete linear dynamical systems (LDS) with sparsity constraints on either control inputs or initial state. The recovery problems ... -
Low delay file transmissions over power constrained quasi-static fading channels
The ubiquitous deployment of battery-operated wireless devices has resulted in the need for efficient low latency power allocation schemes. A common phenomenon in wireless transmission systems is congestion, where the ... -
Mask Estimator Approaches For Audio Beamforming
Beamforming is a family of algorithms and performs a spatial filtering operation that makes it possible to map the distribution of the sources at a certain distance from the microphones and therefore locate the ... -
Nonlinear Optical Enhancement Studies in Silicon-based Resonant Metasurfaces
Metasurfaces are two dimensional arrangements of building blocks called meta-atoms which have been found to be useful to manipulate amplitude, phase, polarization of light at the nanoscale. Using these properties, functional ... -
Performance improvement of meshless methods for practical time domain electromagnetic analyses.
Solution of Maxwell's equations for practical antennas, filters, waveguides and other microwave devices requires use of numerical methods. Popular numerical methods include the finite difference time domain method (FDTD), ... -
Sequential Controlled Sensing to Detect an Anomalous Process
In this thesis, we study the problem of identifying an anomalous arm in a multi-armed bandit as quickly as possible, subject to an upper bound on the error probability. Also known as odd arm identification, this problem ... -
A Two Step Optimal Decoding for PSK and Trellis Coded Modulation in Noisy Index Coding Problem
Index coding is a communication problem in which a server has a set of messages and wants to broadcast them to a set of receivers. Each receiver is interested in a single message, but some of the receivers may have some ...
