A Synthesis study of the radio sky at decametre wavelengths.
This thesis describes an all-sky survey made at 34.5 MHz using the low frequency telescope situated at Gauribidanur, near Bangalore (latitude 13.36 12 N). The antenna system is made up of 1000 dipoles arranged in the ... -
Algorithmic knowledge for a knowledge-based clustering environment.
Clustering is a process of partitioning a given set of objects into meaningful groups. It has potential applications in many areas, including: 1.Image Segmentation, 2. Speech/speaker Classification, 2.ECG Classificati ... -
Algorithms for testing planarity of chordal graphs and hamiltonicity of planar chordal graphs.
Design and analysis of graph algorithms is an active research area in Computer Science. Designing efficient algorithms for graph problems is both challenging and rewarding from the point of view of theory and applications. ... -
Application of exponential power estimator for speech coding
In speech coding, it is known that the Differential Pulse Code Modulation (DPCM) schemes lead to the reduction of bandwidth requirement (by removing the redundancy) as compared to pulse Code Modulation (PCM) schemes, ... -
Codes over galois rings closed under certain monomials
The use of error-control coding in information transmission systems and data storage systems is increasing rapidly. The primary aim of coding theorists has been to find “good codes” with “reasonably simple” decoding methods. ... -
A Compiler and Symbolic Debugger for Occam
(Indian Institute of Science, 2005-03-03)We have implemented Occam, a parallel programming language, on a uniprocessor machine (MC-68020 based HORIZON I11 running on UNIX system V.2) with simulated concurrency. Occam is a descendant of CSP with a few convenient ... -
Design and implementation of a multidimensional multilink multicomputer hardware and software
In this thesis, we propose and implement a multidimensional multilink system (MMS) architecture which uses message passing paradigm between computing elements (CEs). The merits of this architecture are its simplicity, regularity ... -
Diagnostic Reasoning with Surface and Deep Level Knowledge in Medical Domain
The aim of this work is to structure the domain knowledge based upon some conceptual models so that the knowledge can be efficiently used for diagnostic reasoning in medical domain. Medical domain is complex and incompletely ... -
Effect of a QSO on its host galaxy
Various arguments and observations have led to a general belief that QSO phenomenon is a form of violent activity in the nuclei of galaxies. It is natural to expect that a powerful source of high energy radiation like a ... -
A Hybrid Knowledge-Based System for Process Plant Fault Diagnosis
(Indian Institute of Science, 2005-03-11)Knowledge-Based Systems (KBSs) represent a relatively new programming approach and methodology that has evolved and is still evolving as an important sub-area of Artificial Intelligence (AI) research. The most prevalent ... -
Intelligent backtracking in logic programming.
Logic programming languages are being used extensively in the Fifth Generation Computer Project and in the areas of artificial intelligence, knowledge representation, expert systems and other reasoning systems. One very ... -
NMR spectroscopy of oriented systems: studies at and near magic angle sample spinning
The experiments described in this chapter are important in the context of applications mentioned in section 2.2, viz., (i) analysis of spectra of oriented molecules and (ii) use of liquid crystals for measurement of spinning ... -
Optimization techniques applied to the design of integrated rural energy centres
A major part of the energy needs of rural India and many other developing countries is met by non-commercial sources of energy. Considerable amounts of human and animal energy are also being spent in an inefficient manner ... -
Solution of algebraic riccati equations on wavefront array processors
The need for high performance computers has been felt for some time in application areas such as on-line control, system identification and estimation in real-time, complex control system design, etc. Parallel computers ... -
Some aspects of synthesis, structure and stability of quasicrystals.
The celebrated discovery of quasicrystals has broadened our outlook towards the various possibilities of atomic arrangements in the solid state. Many fascinating problems in the field of quasicrystals have emerged, which ... -
Some exact analytic models of time dependent collisionless stellar systems.
This thesis began with the general theme of studying the time-dependent behavior of collisionless self-gravitating systems. It is rather hard to obtain exact, general results by analytical methods (see Mathur 1986 for an ... -
Study of parallel distributed schemes for combinatorial optimization.
This thesis is concerned with Parallel Distributed Optimization techniques for solving Combinatorial Optimization (CO) problems. Given a finite set of configurations and a cost function over them, a CO problem requires ...
