Breast image registration using a textural transformation
(1997-09-01)
Breast cancer could be cured 99.4% if all tumors are detected by the time they reach 0.4 cm. However, since many normal structures in the breast will be of this magnitude, to detect small tumors we need to align two breast ...
Electrical impedance tomography with neural networks and fuzzy sets
(1997-06-01)
Various imaging procedures, providing different types of information and based on different physical properties of the tissues, are characterized by specific complexities, degrees of hazard, resolutions and price. Electrical ...
Artificial neural network and fuzzy logic control for HVDC systems
(1997-07-01)
This thesis comprises the studies and results from the application of artificial neural networks (ANN) and fuzzy logic theory to the control of the high voltage direct current (HVdc) systems. The studies considered their ...
Protection of transmission lines sharing the same right-of-way
(1997-05-01)
The compact transmission configurations such as the double-circuit and multi-phase systems have emerged as a result of the search for compact and efficient systems with minimal environmental hazards. Protective relaying ...
Investigation of protection problems due to geomagnetically induced currents
(1996-10-01)
Geomagnetically Induced Currents (GIC), flowing in power systems during Solar Magnetic Disturbances (SMD), can cause severe offset saturation of power system transformers. Continuous saturation of transformers can result ...
HPP lattice-gas automata for computational electromagnetics
(1998-05-01)
A Lattice-Gas Automaton (LGA) is an unconditionally stable discrete system in which particles with a small and finite number of states move about on a regular lattice. The dynamics of this system are governed by a reversible ...
Soft competitive learning using stochastic arithmetic
(1998-05-01)
Artificial Neural Networks (ANNs) are massively parallel systems which can benefit from technology which allows implementation of an unusually large number of simple computational elements on a single integrated circuit. ...
Pattern recognition techniques as applied to the classification of convective storm cells
(1999-09-01)
This thesis investigates the role of preprocessing, rejection classes and ample relabelling in the classification of convective storm cells. This problem is representative of pattern recognition problems displaying high ...
Multifractal characterization of electromyogram signals
(1999-01-01)
In this thesis, we present an approach to the characterization and feature extraction of the electromyogram (EMG) signals. This approach is based upon the chaotic behaviour of the EMG signals and the existence of the ...
Wireless ATM network management modeling
(1998-04-01)
Wireless personal communication services (PCS) and broadband networking for delivery of multimedia information represent two well-established trends in telecommunications. Given that ATM is now viewed as a universal base ...
