Natural frequencies of 3-phase transformer windings.
The equations of the windings of a 3?phase transformer together with the terminal conditions completely specify the electrical behaviour of the windings. However, they are awkward and difficult to solve. These difficulties ... -
Electromagnetic modelling of the first stroke of a lightningflash
Lightning is one of the most frequently encountered and spectacular natural phenomena which induces disturbances and sometimes damages to electrical and communication systems. Aircrafts, ships, and explosive storage units ... -
Deposition and characterisation of spin-on-oxide (spoxide) using an organosilicon compound
Abstract not available -
VLSI architecture for the parallel computation of power system problems.
The large size and modeling complexities of power system problems have been providing the motivation for the use of fast computers and the search for new algorithms. The present trend of using digital computers for the ... -
Wavelet array transform for signal representation using generalised hermite polynomials
The thesis deals with a framework for the analysis and synthesis of one- and two-dimensional signals, created by a new array of wavelets as basis functions, which are derived from generalized Hermite polynomials. The ... -
A special purpose simd machine for Low-level vision processing
The thesis deals with the design of a parallel computer architecture and a performance analysis of a simulated version of the same, for a class of problems in vision using a relaxation labeling paradigm. The motivation ... -
Reconstruction of signals from the sign data.
This thesis deals with the problem of reconstruction of signals as a function of time or space, from the given information of the type of sign data in the space domain. The problem of signal representation and reconstruction ... -
Computer systems performance evaluation
The use of the mutual nearest neighbourhood concept for solving certain classes of problems in pattern recognition methodology is the main topic of study in this thesis. The concept of mutual nearest neighbourhood, ... -
Hybrid evolutionary algorithms for supervised and unsupervised learning
The main focus of this work is the development of hybrid evolutionary algorithms. Evolutionary Algorithms (EAs) are stochastic optimization algorithms inspired by natural evolution. EAs include Genetic Algorithms (GAs), ... -
Multicriteria games with applications to two-target game problems.
The primary objective of this thesis was to develop new solution concepts for two?person multicriteria games, emphasizing the security aspect of the players’ strategies, and to demonstrate their application to two?target ... -
Hyperspectral Image Fusion with Implicit Regularization
Hyperspectral (HS) satellite images contain rich spectral information but generally suffer from low spatial resolution. In contrast, multispectral (MS) images offer higher spatial resolution but only a limited number of ... -
Fast adaptive multipole-algorithm for scattering from inhomogeneous dielectric cylinders of arbitrary cross-section
The work reported in this thesis is concerned with the rapid solution of electromagnetic scattering problems involving inhomogeneous dielectric cylinders of arbitrary cross?section. In particular, attention is focused on ... -
Coaxial triggered vacum gap : switching and delay characteristics
Vacuum is an excellent insulator, albeit has a poorly defined intrinsic electric breakdown strength. Because of this, the ordinary vacuum gap with only two electrodes is unsuitable for switching applications. The electric ... -
Electrical breakdown and post breakdown studies in sodium vapour using coxial; cylilndrical electrode configuration
The advancing technology of power circuit breakers has led the way for the study of arcs in gas?filled as well as vacuum circuit breakers. The spectroscopic investigations of such arcs have clearly shown the presence of ... -
Pressure gradient flow electrical conduction in polar liquids
Polar liquids like nitro-, chloro- and bromobenzenes find possible applications in electrostatic generators, impulse voltmeters etc. In this work natural conduction in these liquids has been studied at electric fields of ... -
Electrical discharges in mercury vapour in a magnetic field
Langmuir probe method is applied to determine the n? and T? of a low-density, collisional plasma in mercury vapour under moderate magnetic field strengths. The charge density evaluated by Bohm's method and the orbital ... -
Learing automata algorithms for connectionist systems local and global convergence
Connectionist systems have been studied with much interest as models for the brain and also as systems which work in a parallel and distributed manner. These systems exhibit desirable properties such as learning capability ... -
Excitation dynamics in GaAs quantum wells
The dynamics of excitons is studied using time?resolved photoluminescence. We deduce experimentally, for the first time, the intrinsic homogeneous linewidth of free excitons in GaAs quantum wells. The scattering rate of ... -
Measurements of the ionsation current Growth and the ratio of Diffusion coefficient to mobility for electronics in feebly Attaching gases
For a proper understanding of the mechanism of breakdown in gases, it is essential to have knowledge of the swarm coefficients, namely, the sparking potentials (V?), Townsend's primary (?/N) and secondary (?) ionization ...
