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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Numerical investigations of unsteady incompressible boundary - layer flows
This thesis presents a numerical study of some problems in unsteady, laminar incompressible boundary-layer theory. It is divided into five chapters, the first being a general introduction to boundary-layer theory with ... -
numerical studies of laminar compressible boundary layer flows with heat and mass transfer
This thesis presents a numerical study of some laminar compressible boundary-layer flows with heat and mass transfer. It consists of five chapters: the first is an introductory one, the remaining four are concerned with ... -
Numerical study of natural convection boundary layer flows
This thesis presents a numerical study of some laminar natural convection boundary layer flows in isothermal and non-isothermal media. It consists of five chapters. The first is an introductory one; the remaining four are ... -
On the Eikonal equation and shape from shading
This thesis proposes and develops new techniques for the solution of the Shape from Shading (SFS) problem. For a homogeneous Lambertian surface, illuminated by a distant point light source in the direction (p, q, -1) ... -
Phasons,topological defects and dynamics in incommensurate matter
In this thesis, we derive some physical consequences of the existence of a phason mode in incommensurate materials. We consider two main examples of such materials-quasicrystals and the incommensurate twist grain boundary ... -
Reason maintenance and logic
This thesis studies the theory and applications of recison maintenance from a logical perspective. First a series of exam ples introduces the concepts, structures and techniques of reason m aintenance. T he exam ples ... -
Specification environment for distributed real time systems
Real-time computer systems usually find applications in safety-critical areas. Thus, real-time systems need to be extremely reliable. However, most of the real-time systems are inherently "distributed" in nature. The ... -
Studies in learning and representation in connectionist networks
This work deals with questions related to learning and representation in connectionist networks. The main issue taken up in learning is the convergence of local learning rules for feedforward networks. We ask the following ... -
Study of radio emissions from clusters of galaxies: CD galaxies and the very steep spectrum sources
(a) An important conclusion regarding the probability of radio emission associated with the brightest galaxy in the centre of a cluster containing a VSSS (Very Steep Spectrum Source) can be drawn from the study of Table ...
