Study of simulated xy plasma at k-band
Spacing between the wires (in mm) Spacing between the grid structures (in mm) Free-space wavelength (in mm) Simulated plasma frequency (in Hz) Frequency of the oscillator (in Hz) Refractive index Equivalent plasma density ... -
DPLL's for network synchronization: a new approach.
A new DPLL has been described in this thesis to overcome some of the limitations of the conventional second-order DPLL in the context of network synchronization applications. The analytical and computer simulation studies ... -
Design and development of subject storage and learner models for WESLA
With the advent of the web, the Internet has evolved into a user-friendly medium, capable of high-speed on-demand information delivery. Web-based distance learning systems support distributed and asynchronous learning. ... -
Application of coherent optical techniques in the study of serve mathematical operations
The aim of the project is to study some of the mathematical operations by coherent optical processing techniques with the help of gratings. These mathematical operations are namely: (1) Translation (2) Addition (3) ... -
Coherent optical image deblurring with computer generated fourier plane filters
This thesis deals with the fabrication techniques of optical filters for use in a coherent optical processor for correcting images that are degraded by space-invariant blurs. In particular, techniques wherein one can utilize ... -
Kinematical conservation laws and applications
Study of wave motion is important in the field of fluid mechanics. The equations governing the motion of an inviscid compressible fluid form a hyperbolic system of quasi-linear equations and hence give rise to nonlinear ... -
Grushin Multipliers and Toeplitz Operators
This work investigates advanced concepts in functional analysis and partial differential equations, focusing on Sobolev spaces and their weighted variants. The study explores properties of functions in Lp(Rn+1)L^p(\mathb ... -
A Study and development of numerical techniques for the solution of integral equations
We have shown that given any function f(x), there exists a unique f?(x), as defined by the relation (2.1), which exactly coincides with f(x) at the points jh. By using the package MATHEMATICA, we can choose a k, such that ... -
Benard-Marangoni convection and instability in a layered fluid system
Buoyancy-driven instability has been well established since the pioneering work of Rayleigh, who showed that convection, called Bénard convection, occurs only when the Rayleigh number, which is a ratio of buoyancy force ... -
Some aspects of synthesis, structure and stability of quasicrystals.
The celebrated discovery of quasicrystals has broadened our outlook towards the various possibilities of atomic arrangements in the solid state. Many fascinating problems in the field of quasicrystals have emerged, which ... -
Kinetic investigations on gas solid reactions
Gas-Solid Reactions in Metallurgical Processes Gas-solid reactions are of current interest to process metallurgists because of their growing importance in industrial processes. In the present work, investigations were ... -
Assessment of the dielectric behaviour of some liquid impregnated systems
This thesis reports the results of an extensive investigation carried out to develop a possible alternative to polychlorobiphenyls (PCBs) which are being banned in most countries due to their toxicity and poor biodegradability. ... -
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 ... -
Swarm coefficients and the ratio of diffusion coefficients of mobility for electronic in Gases
The use of ever-increasing voltages for transmission of electrical power and nuclear particle accelerators continues to stimulate research into the fundamental aspects of electrical breakdown in gases. A knowledge of primary ... -
AMI-The language and its implementation
Automatic translation of sequential programs to parallel programs which can reasonably exploit distributed memory machines is very difficult and not well-understood. Programming with communication-based statements is very ... -
Nondeterminism and communication in functional progamming systems: a study in formal program development
In this thesis, a Relational Database Management System that supports a query/data manipulation language along with facilities like database creation is presented. A compiler model chosen for translating the input statements ... -
Monitoring program dynamics : Evaluation of software profiler effectiveness
Program monitoring tools are often used to verify program correctness, study program performance, and identify performance bottlenecks. Program profilers are a class of program monitoring tools which aid in tuning the ... -
Interaction paradigms for distributed object-oriented programming
Current trends in large-scale distributed programming on a network of workstations are experiencing a paradigm shift into object-orientation. This is primarily driven by the need for modular, compact, portable and reusable ... -
PEG: a programming environment generator
Integrated piogramming enviionments play an im portant role in making the software development process easier and more efficient. Since there exist a number of programming languages, it is necessary to provide programmers ... -
New techniques for the analysis of two and three dimensional objects
The results of an investigation carried out on certain pattern recognition aspects of a class of two-dimensional line drawings and three-dimensional objects are reported in this thesis. The motivation for the proposed ...
