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 ... -
A Modified Sum-Product Algorithm over Graphs with Short Cycles
(2018-07-18)We investigate into the limitations of the sum-product algorithm for binary low density parity check (LDPC) codes having isolated short cycles. Independence assumption among messages passed, assumed reasonable in all ... -
Savitzky-Golay Filters and Application to Image and Signal Denoising
(2018-07-18)We explore the applicability of local polynomial approximation of signals for noise suppression. In the context of data regression, Savitzky and Golay showed that least-squares approximation of data with a polynomial of ... -
Small Signal Stability Analysis of a Power System with a Grid Connected Wind Powered Permanent Magnet Synchronous Generator (PMSG)
(2018-07-18)Small signal oscillation has been always a major concern in the operation of power systems. In a generator, the electromechanical coupling between the rotor and the rest of the system causes it to behave in a manner similar ... -
Robust Nonparametric Sequential Distributed Spectrum Sensing under EMI and Fading
(2018-07-16)Opportunistic use of unused spectrum could efficiently be carried out using the paradigm of Cognitive Radio (CR). A spectrum remains idle when the primary user (licensee) is not using it. The secondary nodes detect this ... -
Optical WDM Systems for Multi-point Distribution of Hybrid Signals in Phased Array Radar Applications
(2018-07-16)Photonics and Optical techniques have advanced recently by a great extend to play an important role in Microwave and Radar applications. Antenna array of modern active phased array radars consist of multiple low power ... -
Dynamic Headpose Classification and Video Retargeting with Human Attention
(2018-07-14)Over the years, extensive research has been devoted to the study of people's head pose due to its relevance in security, human-computer interaction, advertising as well as cognitive, neuro and behavioural psychology. One ... -
Supervised Classification of Missense Mutations as Pathogenic or Tolerated using Ensemble Learning Methods
(2018-07-09)Missense mutations account for more than 50% of the mutations known to be involved in human inherited diseases. Missense classification is a challenging task that involves sequencing of the genome, identifying the variations, ... -
Compilation of Graph Algorithms for Hybrid, Cross-Platform and Distributed Architectures
(2018-07-09)1. Main Contributions made by the supplicant: This thesis proposes an Open Computing Language (OpenCL) framework to address the challenges of implementation of graph algorithms on parallel architectures and large scale ... -
Towards a Charcterization of the Symmetries of the Nisan-Wigderson Polynomial Family
(2018-07-09)Understanding the structure and complexity of a polynomial family is a fundamental problem of arithmetic circuit complexity. There are various approaches like studying the lower bounds, which deals with nding the smallest ... -
On Codes for Private Information Retrieval and Ceph Implementation of a High-Rate Regenerating Code
(2018-07-09)Error-control codes, which are being extensively used in communication systems, have found themselves very useful in data storage as well during the past decade. This thesis deals with two types of codes for data storage, ... -
Stochastic Approximation Algorithms with Set-valued Dynamics : Theory and Applications
(2018-07-05)Stochastic approximation algorithms encompass a class of iterative schemes that converge to a sought value through a series of successive approximations. Such algorithms converge even when the observations are erroneous. ... -
Ranking from Pairwise Comparisons : The Role of the Pairwise Preference Matrix
(2018-07-05)Ranking a set of candidates or items from pair-wise comparisons is a fundamental problem that arises in many settings such as elections, recommendation systems, sports team rankings, document rankings and so on. Indeed it ... -
Secret Key Generation in the Multiterminal Source Model : Communication and Other Aspects
(2018-07-04)This dissertation is primarily concerned with the communication required to achieve secret key (SK) capacity in a multiterminal source model. The multiterminal source model introduced by Csiszár and Narayan consists of a ... -
Optimal Mechanisms for Selling Two Heterogeneous Items
(2018-07-04)We consider the problem of designing revenue-optimal mechanisms for selling two heterogeneous items to a single buyer. Designing a revenue-optimal mechanism for selling a single item is simple: Set a threshold price based ... -
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 ... -
Efficient Static Analyses for Concurrent Programs
(2018-06-29)Concurrent programs are pervasive owing to the increasing adoption of multi-core systems across the entire computing spectrum. However, the large set of possible program behaviors make it difficult to write correct and ... -
