Engineering 2D Materials and Heterostructures for Advanced Gas Sensing and Molecular Memory Devices
The increasing need for monitoring environmental health has spurred the search for advanced sensing materials to create energy efficient, low cost, light weight gas sensing systems. The inherent attributes of 2D materials, ... -
Design,fabrication and instrumentation of a broadcast bus multicomputer system
In this thesis, we propose, design, and give the implementation details of a Multicomputer System called the Broadcast Bus Multicomputer System (BBMS). We also model the message broadcast bus and compare the analytical ... -
Study of giant radio galaxies.
Within the framework of the beam model, we have deduced some basic physical parameters of the jets and hotspots associated with classical double radio sources, following a simple approach which is based on the assumptions ... -
Dissipative dynamics of classical and quantum systems
We have calculated the dynamic structure factor for tethered surfaces in the concentrated and semi-dilute regimes. We also calculated the concentration dependence of the diffusion constant and the coefficient of form ... -
Charged solution excitations and the vaccum state of.. field theories
This thesis describes some theoretical investigations on ?? field theories (i.e., theories governed by Lagrangians which are sixth-degree polynomials in ?) where ? is either a real or a complex scalar field. We work in one ... -
Topics in the statistical mechanics of extended objects
In this chapter, we have presented a theory for muon-spin-rotation (?SR) spectra in anisotropic, layered superconductors, incorporating thermal effects in both the solid and liquid phases. We now discuss, in some detail, ... -
Study Of the Cometary Globules in the Gum Nebula
From our analysis of the measured velocities of cometary globules (CGs), we draw the following conclusions: Kinematic Interpretation The motion of the CGs cannot be explained by a model dominated by galactic rotation, ... -
Study of radio emissions from clusters of galaxies: CD galaxies and the very steep spectrum sources
(a) An important conclusion regarding the probability of radio emission associated with the brightest galaxy in the centre of a cluster containing a VSSS (Very Steep Spectrum Source) can be drawn from the study of Table ... -
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 ... -
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 ... -
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 ... -
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 ... -
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)=? ...
