Effect of valve element characteristics, stray capacitance and voltage harmonics on surge arrester diagnostics
(2001-05-01)
Metal Oxide Surge Arresters (MOSA) degrade in service under the influence of constant working voltage, internal partial discharges, non-uniform voltage distribution, possible moisture ingress and the occurrence of transient ...
Reducing latency on the Internet using Component-Based Download and File-Segment Transfer Protocol
(2001-03-01)
This thesis examines the Component-Based Download (hereinafter referred to as "CBD") and the Component-Based Download File-Segment Transfer Protocol (hereinafter referred to as "CBD-FSTP") to combat the latency due to the ...
Application of lattice gas automata to electromagnetic scattering and transmission line modelling
(2000-05-01)
Lattice gas automata consist of particles within a lattice that interact with their nearest neighbours according to simple deterministic rules. Essential parts of the algorithm can be implemented in a few lines of code, ...
Coplanar waveguide structures on micromachined glass substrates
(2001-06-01)
Micromachining is currently being studied to help reduce the packaging and integration costs of multi-chip modules (MCMs) in radio frequency (RF) systems. Such systems require the integration of radiating elements, feed ...
Simulation models relevant to the protection of synchronous machines and transformers
(2001-04-01)
The purpose of this research is to develop models which can be used to produce realistic test waveforms for the evaluation of protection systems used for generators and transformers. Software models of generators and ...
Field testing, modelling and analysis of ferroresonance in a high voltage power system
(2000-08-01)
Catastrophic equipment failures continue to occur today due to ferroresonance even though this phenomenon has been extensively studied over the past ninety years. This thesis is concerned with the tasks of defining where ...
A simplified scattering synthesis method for LC ladder filters
(2000-05-01)
This thesis is devoted to the presentation of a simplified synthesis method and its application in the development of a computer program for the synthesis of LC ladder networks. The approach developed in the thesis is based ...
Electromagnetic scattering by numerical methods applicable for large structures
(2000-07-01)
The objective of this research is to develop numerical methods for general and efficient solutions to the linear systems obtained using the integral equations arising from electromagnetic scattering problems involving ...
Interaction of electromagnetic waves with biological tissue
(2001-05-01)
The interaction of electromagnetic waves with biological tissue is investigated. Two problems in particular are studied. The first is three-dimensional scattering from biological tissue taking into consideration its ...
Design and implementation of odd-order wave digital lattice lowpass filters, from specifications to Motorol DSP56307EVM module
(2001-06-01)
This thesis is dedicated to applying and developing explicit formulas for the design and implementation of odd-order lattice Lowpass wave digital filters (WDFs) on a Digital Signal Processor (DSP), such as a Motorola ...
