Observational Aspects Of Core Collapse Supernovae
(2013-10-17)The discovery of several bright supernovae (SNe) in recent years has evoked a great deal of interest in these objects. The study of these objects are of importance not only as probes to the end stages of stellar evolution, ... -
Observational study of Core-Collapse Supernovae
The advent of dedicated surveys for studying transient events has invoked a great interest in the study of supernovae (SNe). The rate of discovery of SNe has hence gone up ten-fold relinquishing their diversity. SNe not ... -
Observed Subseasonal Variability Of Temperarture And Salinity In The Tropical Indian Ocean
(2013-06-10)Subseasonal variability of tropical Indian Ocean sea surface temperature is thought to influence the active-break cycle of the Asian monsoon. There are several open questions related to the role of surface fluxes, large-scale ... -
An Ocean General Circulation Model Study Of The Arabian Sea Mini Warm Pool
(2009-07-17)The most important component of the climate system over the Indian Ocean region is the southwest monsoon, which dictates the life and economy of billions of people in the tropics. Being a phenomena that involves interaction ... -
Odor Source Localization Using Swarm Robotics
(2010-06-02)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 ... -
Oleosin, a Bifunctional Enzyme is Phosphoregulated by a Protein Kinase
In eukaryotic cells, lipids are indispensable principal components that vitiate biological life. Lipids are classified into two major groups, polar and non-polar lipids. Polar lipids are phospholipids, whereas non-polar ... -
On A Cubic Sieve Congruence Related To The Discrete Logarithm Problem
(2013-05-21)There has been a rapid increase interest in computational number theory ever since the invention of public-key cryptography. Various attempts to solve the underlying hard problems behind public-key cryptosystems has led ... -
On a Divide-and-Conquer Approach for Sensor Network Localization
(2018-08-20)Advancement of micro-electro-mechanics and wireless communication have proliferated the deployment of large-scale 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
(2018-04-18)We discuss two topics in this talk. First we study compact Ricci-flat four dimensional manifolds without boundary and obtain point wise restrictions on curvature( not involving global quantities such as volume and diameter) ... -
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 Asymmetric Distributed Source Coding For Wireless Sensor Networks
(2011-01-19)We are concerned with addressing the worst-case distributed source coding (DSC) problem in asymmetric and interactive communication scenarios and its application to data-gathering wireless sensor networks in enhancing their ... -
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, ... -
On Critical Points of Random Polynomials and Spectrum of Certain Products of Random Matrices
(2018-07-30)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
(2018-06-13)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
(2013-06-21)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
(2008-01-29)Kullback-Leibler relative-entropy or KL-entropy 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 ...
