Odor Source Localization Using Swarm Robotics
(20100602)Locating an odor source in a turbulent environment, an instinctive behavior of insects such as moths, is a nontrivial task in robotics. Robots equipped with odor sensors ﬁnd it diﬃcult to locate the odor source due to the ... 
On A Cubic Sieve Congruence Related To The Discrete Logarithm Problem
(20130521)There has been a rapid increase interest in computational number theory ever since the invention of publickey cryptography. Various attempts to solve the underlying hard problems behind publickey cryptosystems has led ... 
On a DivideandConquer Approach for Sensor Network Localization
(20180820)Advancement of microelectromechanics and wireless communication have proliferated the deployment of largescale wireless sensor networks. Due to cost, size and power constraints, at most a few sensor nodes can be equipped ... 
On an ODE Associated to the Ricci Flow
(20180418)We discuss two topics in this talk. First we study compact Ricciflat four dimensional manifolds without boundary and obtain point wise restrictions on curvature( not involving global quantities such as volume and diameter) ... 
On Applications of 3DWarping 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 Asymmetric Distributed Source Coding For Wireless Sensor Networks
(20110119)We are concerned with addressing the worstcase distributed source coding (DSC) problem in asymmetric and interactive communication scenarios and its application to datagathering wireless sensor networks in enhancing their ... 
On Codes for Private Information Retrieval and Ceph Implementation of a HighRate Regenerating Code
(20180709)Errorcontrol 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, ... 
On Critical Points of Random Polynomials and Spectrum of Certain Products of Random Matrices
(20180730)In the first part of this thesis, we study critical points of random polynomials. We choose two deterministic sequences of complex numbers, whose empirical measures converge to the same probability measure in complex plane. ... 
On Design and Analysis of Energy Efficient Wireless Networks with QoS
(20180613)We consider optimal power allocation policies for a single server, multiuser wireless communication system. The transmission channel may experience multipath fading. We obtain very efficient, low computational complexity ... 
On Dimensional Parameters Of Graphs And Posets
(20130621)In this thesis we study the following dimensional parameters : boxicity, cubicity, threshold dimension and poset dimension. While the ﬁrst three parameters are defined on graphs, poset dimension is defined on partially ... 
On Generalized Measures Of Information With Maximum And Minimum Entropy Prescriptions
(20080129)KullbackLeibler relativeentropy or KLentropy of P with respect to R deﬁned as ∫xlnddPRdP , where P and R are probability measures on a measurable space (X, ), plays a basic role in the deﬁnitions of classical information ... 
On Learning kParities and the Complexity of kVectorSUM
(20180206)In this work, we study two problems: first is one of the central problem in learning theory of learning sparse parities and the other kVectorSUM is an extension of the not oriouskSUM problem. We first consider the problem ... 
On Maximizing The Performance Of The Bilateral Filter For Image Denoising
(20170707)We address the problem of image denoising for additive white Gaussian noise (AWGN), Poisson noise, and Chisquared noise scenarios. Thermal noise in electronic circuitry in camera hardware can be modeled as AWGN. Poisson ... 
On Modeling Of Constrained Piezoelectric Thin Films For Structural Health Monitoring
(20100101)The behaviour of a freestanding thin film differs from that of a film surfacebonded or embedded due to the boundary constraints. A general dearth of analytical models, in regard to prediction of the operational competence ... 
On Network Coding and NetworkError Correction
(20180424)The paradigm of network coding was introduced as a means to conserve bandwidth (or equivalently increase throughput) in information ﬂow networks. Network coding makes use of the fact that unlike physical commodities, ... 
On PerceptionBased Image Compression Schemes
