Constrined hamiltonian dynamics geometric structure and application to relativistic particle machanics
The study of constrained dynamical systems has gained importance in recent years, following the realisation that they are often found in nature. The subject developed out of efforts to recast Einstein's theory of gravitation ... -
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 ... -
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 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 ... -
Surface explosive instabilities in a beam plasma system
Explosive instability due to non?linear wave–wave interaction is one of the most interesting phenomena in non?linear plasma theory. Since it is widely recognized that plasma, either in nature or in laboratory, is bounded ... -
Unsteady laminar boundary layer studies through finite difference methods
This thesis embodies a study of some problems in unsteady laminar compressible and incompressible boundary layer theory. The thesis is divided into five chapters. Each chapter contains a brief survey of the literature relevant ...
