Studies in laminar boundary layer theory with suction or injection
Chapter I deals with the solution of the full Navier-Stokes equations in the neighbourhood of the leading edge in the presence of suction. We obtain exact solution further downstream on the basis of boundary layer equations ... -
Some dual realizations of Bergman and Hardy spaces on convex domains via integral transforms
The Fantappi{\`e} and Laplace transforms identify abstract spaces of analytic functionals with concrete function spaces, converting geometric support conditions into analytic growth conditions. Specifically, the space of ... -
Kobayashi geometry and a metric notion of negative curvature
In this thesis, we study some problems that represent various aspects of Kobayashi geometry. Our problems are, in some sense, motivated by a close examination---which forms a part of this thesis---of a property that may ... -
Some magneto-hydrodynamical problems with an application to astoronomy
Part A: A steady flow with the effect of a controlling field of low conductivity past a rotating cylindrical surface in the case of a dissipative medium and its corresponding flow past a magnetized sphere. Part B: The ... -
Stability and allied problems in magnetohydrodynamics
We note that the expressions (1.20)�(1.27) are real for all real values of the angular momentum MMM. In the numerical computations, we fixed V0V_0V0? and MMM, then obtained the values of (r,z)(r, z)(r,z) from the given ... -
Finite field computational techniques for exact solution of numerical problems
In this dissertation, we consider the application of residue arithmetic for the exact computation of g-inverses in order to obviate the round-off errors normally associated with their computation. It turns out that for ... -
Secondary flows and heat transfer in non-newtonian fluids
The thesis consists of four chapters. In chapter I we have described the non-Newtonian fluids which we have discussed in the text and have also derived the equations of motion in the systems of coordinates which we have ... -
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 ... -
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 ... -
Nega-base computer arithemetic-theory and applications
This dissertation presents a detailed study of negative base number representation—the theory as well as the development of suitable algorithms for building the arithmetic unit of a digital computer. The idea of negative ... -
Some flow and heat transfer problems with special reference to numerical procedures
This thesis deals with elegant application of certain known mathematical methods and with certain numerical procedures devised to obtain solutions of the differential equations arising in the flow and heat transfer ... -
Three Dimensional Boundary Layer with suction and injection
Chapter I deals with the study of incompressible boundary layer over a yawed semi-infinite flat plate with suction or injection by modified Pohlhausen method. IN the first two parts, a comparison of three different velocity ... -
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 ... -
Computations in linear algebra: a new look at residue arithmetic.
The dissertation deals with error-free and approximate computations of some problems in linear algebra, with an emphasis on a modified residue arithmetic developed here. It is divided into five chapters:Chapter 1 The ... -
Boundary element method applied to fluid flow problems
This research work is a study of fluid flow problems by the Boundary (Finite) Element Method. The widely used Finite Element Method has the advantages of its flexibility in choosing the shape and size of the elements, the ... -
Ergodic and adaptive control of markov processes.
We address the problem of controlling two classes of Markov processes, viz., Markov chains and diffusion processes. Our main goal is to minimize a long-run average cost criterion (or ergodic cost criterion) associated with ... -
some nonlinear surface wave propagation problems
This thesis contains the results of investigations of some nonlinear surface wave propagation problems. It is divided into six chapters, of which Chapter I is the general introduction and the concluding remarks constitute ... -
Some results on finite section linear integral operators
This thesis deals mainly with some spectral properties of finite section linear integral operators from L2[0,t]L^2[0,t]L2[0,t] into itself, defined as Ttf(x)=?0tK(x,y)f(y)?dyT_t f(x) = \int_0^t K(x,y) f(y) \, dyTt?f(x)=? ... -
Enumerative considerations of SDR's and latin rectangles
The art of counting is interesting but often 120000103 a difficult task. It requires computational skills^ ' .. ability to recognise similar patterns and a little mastery of general principles and simplification ... -
Some boundary value problems in elasticity with and without magnetic field
In our paper, in order to solve the problem we need the knowledge of three analytic functions 4>(z), and f^(z).. In the case of plane magneto-elasticity we arrive at a homogeneous biharmonic equation, as is the case ...
