A digital correlation receiver for the Gauribidanur Decametre wave radio telescope
A low-frequency radio telescope operating at 34.5 MHz has been set up at Gauribidanur (Latitude: 13°36′12″ N, Longitude: 77°26′07″ E) in the form of a T-shaped array antenna. It consists of: A 1.38 kilometre long array ... -
An integrated relational database for computer-aided design applications
In view of the widespread use of Computer Aided Design (CAD) systems, the problem of storing data efficiently (in terms of memory requirements and the time required to access it) is of considerable importance. This thesis ... -
Conformational studies on polynuc leotides and nucleic acids
After an introduction to the nucleic acids and the conformational studies on them at the monomeric and polymeric levels, the need for investigations on the conformations of 3?-nucleotides is outlined. The significance of ... -
Electrical breakdown and post breakdown studies in sodium vapour using coxial; cylilndrical electrode configuration
The advancing technology of power circuit breakers has led the way for the study of arcs in gas?filled as well as vacuum circuit breakers. The spectroscopic investigations of such arcs have clearly shown the presence of ... -
Esperimental techniques and of electrical properties of critical binary liquid systems
A direct analysis of the resistance and capacitance data did not yield any unambiguous result on the value of the exponent ?. Both resistance and capacitance behave in a similar way, and the ? value seems to depend upon ... -
Generalized light rays and relativistic front dynamics : theory and application to paraxial optics
We recount here briefly the main advantages of using the front form for paraxial wave problems. It leads to a clean separation of the space-time variables into the combinations on each of which the amplitude has a ... -
Hydromagnetic surface waves
The ASW propagates as a dispersive wave along the boundaries of a bounded plasma column. At the interface of a plasma slab surrounded by two identical plasma media, two modes-symmetric and asymmetric-propagate with a phase ... -
Iterative and direct P;Adic algorithms for exact solution of numerical problems
In this chapter, we have described an O(n³), 2 < P < 3 algorithm for inverting integer matrices using p-adic computations. Some of the important aspects of this method are: (a) Absence of any convergence problems – the ... -
Mathematical models of some physiological system
This thesis presents some theoretical investigations on certain problems concerning the respiratory, excretory, and circulatory systems in human physiology, from a fluid mechanics point of view. It consists of an introductory ... -
Membership algorithms for dependencies in relatinal databases
In relational database theory, a class of dependencies that includes functional dependencies (FDs), multivalued dependencies (MVDs), and join dependencies (JDs) has been found to play an important role in the process of ... -
Norrish type 1 Cleavage reactions of cyclobutanethiones and media
The thesis entitled "Norrish Type I ?-Cleavage Reactions of Cyclobutanethiones and Photochemical Studies in Micellar Media" has been divided into two parts. Part I deals with the strain-assisted ?-cleavage reactions of ... -
Prebreakdown studies in binary mixtures of electronegative and buffer gases
Electronegative gases of high dielectric strength such as SF?, CCl?F?, etc., are extensively used as a gaseous insulating medium in high voltage transmission systems and power apparatus. Such gases are expensive, and hence ... -
Solutions of some rasially symmetric problems of heat conduction with phase change
Some analytical and numerical solutions pertaining to radially symmetric problems of heat conduction with phase change have been presented in this thesis. The emphasis is on finding the growth rate of the moving boundary. ... -
Some flow problems in noncoaxial rotating systems
We live in an atmosphere of air and water which involve rotation to a greater or lesser extent. The atmosphere and the oceans rotate as a whole with the earth and move over its surface as winds and ocean currents which ... -
Studies on graph grammars : comparison of various models and applications to graph theory
In this short chapter we shall raise a few questions whose answers could throw further light on the theory of graph grammars. When the notion of contextual condition was introduced by Rosenfeld, the grammars were constructed ... -
Studies on hydrodynamics and liquid-solid contacting in trickle-bed reactors
In trickle-bed reactors, gas and liquid flow concurrently downwards over fixed beds of catalysts. The reactors find wide application for three-phase contacting in chemical, petrochemical, petroleum and fermentation industries, ... -
Studies on methods of reducing some cost parameters in microprogrammed digital computers and distributed processing systems
The concept of microprogramming is frequently employed in designing the control units of modern digital computers and microprocessors. In a microprogrammed digital computer, the size of control memory depends upon the width ... -
Studies on phase transitions in crystals
The present Raman spectroscopic observations of the mixed crystals of ammonium and potassium sulphate in the paraelectric phase show that as the concentrations of K? ions increase in the crystal, the frequency of totally ... -
Study of coupled spin system using two dimensional NMR spectroscopy
Chapter 1 contains a review of various 2D NMR techniques, their applications and an outline of this work. The theory of spin?echo multiple?quantum spectroscopy of strongly coupled spin systems and that of other 2D NMR ...
