Management is a vibrant and multi phase dynamic process, just like social, scientific and engineering processes, that involves a wide spectrum of activities such as planning, coordination, communication, policy framing, ...
The various topological concepts and properties like openness, closedness, continuity, compactness, connectedness etc. have been generalised by mathematicians. In this thesis we have studied these generalisations and made ...

Classification is a deep and fundamental problem in every branch of Mathematics. Although an uphill task, this target has been achieved in a number of cases in different fields. In general, the strategy for this grand ...
In many branches of Mathematics, a strategy for study of the mathematical entities is to view them as being made up of simpler entities in one or more ways. The task is then divided into two parts: (i) identifying and ...
Effects of the molecular, normal optical Woods-Saxoo and squared Woods-Saxon (Michel) ~-nucleus potentials on the 27 Al(a.,tf1 Si. 21.l9.:w>Si(a.,d)30.31 ,32P and 21S(a.,p)31P reactions have been studied. The parameters ...
Cupric oxide (CuO) and Cadmium sulphide (CdS) thin films have been deposited on glass substrates by chemical spray pyrolysis technique and their structural, electrical and optical properties were studied. Film growth aspects ...
Investigations have been carried out on spray pyrolysed
undoped and indium doped ZnO thin films for the thickness range
700-4000 A. The undoped ZnO thin films were found to be nonstoichiometric
but homogeneous and ...
In order to find the approximate numerical solution to a system of nonlinear equations as well as an integral and a differential operator equations, Newton's algorithm is widely used. L. V. Kantorovich [1948] and Moore ...
This thesis studies the nature of distributive nearlattices. By a nearlattice S we will always mean a (lower) semilattice which· has the property that any two elements possessing a common upper bound,have a supremum, Cornish ...

In this work, we deal with the two types of variational inclusions. Firstly, we consider
the variational inclusion problem of the form
0 ∈ ζ(¯s) + g(¯s) + ξ(¯s), (A)
where S and T are Banach spaces, ζ : S → T is ...

Turbulence means agitation, commotion and disturbance. This definition is, however too general and does not suffice to characterize turbulent fluid motion in the modern sense. Osborn Reynolds in the study of turbulent ...
This thesis studies extensively the finitely generated n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor in studying the kernels around a particular element n, of a skeletal ...

Fixed point theory has fascinated hundreds of researchers since 1922 with the celebrated Banach’s fixed point theorem. Fixed point iterative procedures are one of the early achievements of fixed point theory for their ...

Infant and under-five mortality are the sensitive indices of development and often
reflect a country's quality of life. But there is little understanding of whether
Bangladesh will be capable of achieving all of the ...
A theoretical study of oxygen diffusion process through living tissues and its various consequences have been presented. In this aspect we have reviewed some physiological terms and fundamental lows of diffusion.
A ...
This is an elaborate discussion of main theme ideas and the condition in "Fluid mechanics", which help us to realized a clear concept of the background and elements of various viscous Newtonian and non-Newtonian flow ...

This thesis studies the nature of standard n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor. For a fixed element n of a lattice L, a convex sublattice containing n is called ...
Turbulent motions are very common in nature. The theory of turbulent motion has received considerable attention in recent developments of high-speed jet aircraft, plasma physics and chemical engineering. The formation of ...
The first chapter is a general introductory chapter and gives the general idea of turbulence, distribution functions and their principal concepts. Some results and theories which are needed in the subsequent chapters have ...
