Information-rich Sampling of Time-varying Signals
Confrontation with signal non-stationarity is a rule rather than an exception in the analysis of natural signals, such as speech, animal vocalization, music, bio-medical, atmospheric, ans seismic signals. Interestingly, ... -
Integrated Optical Double Ring Resonators with MEMS for Pressure and Acceleration Sensing
Silicon Photonics has become a signi ficant area of research in last three decades because of its high speed operation, low power consumption and the most important feature, resistant to electro-magnetic interferences. ... -
Integrating Read-Copy-Update Synchronization and Memory Allocation
The evolution of multicore systems with thousands of cores has led to the exploration of non-traditional procrastination-based synchronization techniques such as Read-Copy- Update (RCU). Deferred destruction is the ... -
Investigations on Multilevel Voltage Space Vectors Generated by Stacked and Cascaded Basic Inverter Cells with Capacitor Voltage Control for Induction Motor Drives
Induction motor drives (IMD) require a DC-AC inverter system to obtain variable frequency operation. Generally, IMD uses conventional 2-level inverters. The conventional 2-level inverter has its pole switching between zero ... -
Investigations on Stacked Multilevel Inverter Topologies Using Flying Capacitor and H-Bridge Cells for Induction Motor Drives
(2018-09-04)Conventional 2-level inverters have been quite popular in industry for drives applications. It used pulse width modulation techniques to generate a voltage waveform with high quality. For achieving this, it had to switch ... -
Investigations on the Corona Degradation of Polymeric Insulating Samples
Insulators play an important role in the reliability and safe operation of EHV/UHV transmission lines. Recently several utilities in the country and elsewhere are using polymeric insulators for the high voltage transmission ... -
IO Pattern Aware Methods to Improve the Performance and Lifetime of NAND SSD
Modern SSDs can store multiple bits per transistor which enables it to have higher storage capacities. Low cost per bit of such SSDs has made it a commercial success. As of 2018, cells with an ability to store three bits ... -
Model Checking Temporal Properties of Presburger Counter Systems
Counter systems are a well-known and powerful modeling notation for specifying infnite state systems. In this thesis we target the problem of checking temporal properties of counter systems. We address three predominant ... -
Modeling and Adaptive Scheduling Strategies for Distributed Graph Algorithms
Graph processing at scales of millions-billions of vertices and edges has become common to solve real-world problems in domains like social networks, smart cities and genomics. Distributed "Big Data" platforms for graph ... -
Modulation of Power Electronic Converter Fed Split-phase Induction Machine Drive
Induction machine (IM) is the workhorse of several industries due to its low cost and minimal maintenance. Power electronic converters play a major role in driving IMs which give better flexibility in these applications. ... -
Multiview Registration Using Rank-Constrained Semide nite Programming
We consider the problem of reconstructing a 3D surface from its multiview scans. Typically, the computational pipeline for this problem has two phases: (I) finding point-to-point correspondences between overlapping scans, ... -
On Applications of 3D-Warping and An Analysis of a RANSAC Heuristic
In recent years communication of the scene geometry is gaining importance. With development of technologies such as head mounted displays and Augmented Reality (AR) the need for efficient 3D scene communication is becoming ... -
On Reduced-State Optimal Scheduling for Decentralized Medium Access Control of Wireless Data Collection Networks
In the Internet of Things (IoT), devices such as sensors and actuators will almost invariably be connected to the Internet via wireless networks. The sensor and actuator devices in such systems will be resource challenged ... -
On Some Questions Involving Prefix Codes
Let A be a finite alphabet and A be the set of all finite sequences of the elements of A. A word is any member of A . A prefix code X is a set of words satisfying the prefix property, i.e., no word in the set is a prefix ... -
Optimal Relay Selection in Interference-Constrained Underlay Cooperative Cognitive Radio
Cognitive radio (CR) promises to significantly improve the utilization of scarce wireless spectrum. In the underlay mode of CR, which is the focus of the thesis, a secondary user (SU) can simultaneously transmit on the ... -
Optimal Routing and Data Transmission for Multi-Hop D2D Communications
Device-to-Device (D2D) communication, which enables direct link communication between nodes without going through the infrastructure, has received considerable attention in recent years, particularly in the context of ... -
Phase Retrieval and Hilbert Integral Equations – Beyond Minimum-Phase
(2018-07-18)The Fourier transform (spectrum) of a signal is a complex function and is characterized by the magnitude and phase spectra. Phase retrieval is the reconstruction of the phase spectrum from the measurements of the magnitude ... -
