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, ...
Non-invasive internal pattern extraction of integrated circuits using electrostatic force microscopy
(1999-05-01)
Improvements in technology of the microelectronic areas have allowed researchers to develop Integrated Circuits (ICs) with higher speed and smaller size. However these improvements have also increased the difficulties for ...
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 ...
DSP-based control strategies for an inverter-based compensator
