A Stochastic dynamical system for edge detection
A new stochastic algorithm for edge detection has been presented. This algorithm is based on time-homogeneous Markov chains with the same kind of transition probabilities as in Monte Carlo algorithms and is inherently ... -
Algorithms for some problems on trees and graphs
Design and analysis of graph algorithms is an active area of research in Computer Science. Trees form an important subclass of graphs and have vast applications. In this thesis, we present some new algorithmic results on ... -
Analysis of some unsteady laminar boundary - layer flows using numerical methods
This thesis presents the analysis of the numerical investigations of some unsteady laminar incompressible boundary?layer flow problems. It consists of five chapters. The first chapter deals with a general introduction to ... -
Architecture, Performance and Applications of a Hierarchial Network of Hypercubes
(Indian Institute of Science, 2005-02-09)This thesis, presents a multiprocessor topology, the hierarchical network of hyper-cubes, which has a low diameter, low degree of connectivity and yet exhibits hypercube like versatile characteristics. The hierarchical ... -
Characterization, properties and dynamics of squeezed states: single mode and multimode systems
Squeezed states of the quantized electromagnetic field, as well as the squeezing phenomenon in the more general quantum mechanical context, have been topics of enormous interest recently. In addition to a very large number ... -
Chemistry of spironapthalelenones - synthesis and reactions of oxygen and nitrogen heterocycles
The thesis entitled "CHEMISTRY OF SPIRONAPHTHALENONES – SYNTHESIS AND REACTIONS OF OXYGEN AND NITROGEN HETEROCYCLES" is presented in four chapters and an appendix. Chapter I is divided into two sections. Section I deals ... -
Combustion synthesis and properties of fine particle oxide materials: studies on Ferrites
Synthesis of oxide materials with desired structure and properties is of prime importance in Solid State Chemistry and Materials Science. Since the discovery of superconductivity in oxide ceramics, there has been renewed ... -
Electrochemical studies of sealed lead-acid battery electrode reactions
Sealed lead-acid battery (SLA), also called valve-regulated lead-acid battery (VRLA), is the subject of considerable research efforts at the present time. There are, however, a few outstanding problems to be solved to ... -
Electron Tunneling Studies on Normal and Superconducting oxides
In this final chapter, we shall summarize our important observations and suggest improvements and problems for further investigation. This research has been a learning experience for us as we had no prior experience in the ... -
Estimation of thermophysical properties of binary organic solutions- surface tensions
Thermophysical properties present an interesting field of research to understand molecular nature and behaviour. The primary reason is that these properties mirror any change at the molecular level. One such property is ... -
Evolutionary design of plan based pattern recognition systems in complex domains
Many real-life Pattern Recognition (PR) problems do not fit into the classical PR paradigms. Such systems are currently being implemented using knowledge-based approaches. Designing such systems is an involved, evolutionary ... -
Excitation dynamics in GaAs quantum wells
The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ... -
Flow in pipes of uniform and non-uniform cross-sections with physiological applications
Laminar flow in pipes and channels with uniform and non-uniform cross-sections plays an important role in many engineering and physiological flow problems. Flow of blood through catheterised and stenosed (constricted) blood ... -
Informational Asymmetry in Agency, Bargaining and Market Contexts
The standard micro-economic theory, as epitomized by Walras-Arrow -Debreu’s “General equilibrium theory", assumes that all the economic agents have complete information about their environment. But one comes across many ... -
Instruction scheduling for RISC processors
Instruction scheduling is the process of reordering instructions (whether assembly code or code in some other form) so as to make fuller use of the resources provided by the processor. In the case of RISC processors, ... -
Labelled clustering and its applications
Clustering is a process of grouping a collection of objects. Clustering approaches can be broadly categorized into conventional and knowledge-based approaches. In a conventional approach, objects are typically represented ... -
Lexicalisation of montague semantics: a unified approach to semantic interpretation
This thesis presents the X/LTAG model, a novel framework for semantic representation that integrates the Lexicalized Tree Adjoining Grammar (LTAG) formalism of Arvind Joshi with the possible world semantics of Richard ... -
Low temperature synthesis & characterization of fine particle perovskite oxide & structurally rlated mixed metal oxides
This thesis concentrates on the precursor chemistry of simple and mixed metal carboxylates, especially the citrates and tartrates. The carboxylate process is simple, convenient and most efficient to synthesize fine powders ... -
Motifs in proteins: Disulfide constraints and their applications to protein engineering and peptide modelling
By carrying out a detailed data analysis of 175 PP motifs in proteins, sequence–structure relationships were identified for linking loops 1–5 residues long. Conformational families were recognized in 1-, 2-, 3-, and 4-residue ...
