Planarity testing and embedding algorithms.
(1990)This thesis deals with several aspects of planar graphs, and some of the problems associated with nonplanar graphs. Chapter 1 is devoted to introducing some of the fundamental notation and tools used in the remainder of ... 
Packing problems on a PC.
(1991)Bin packing is a problem with many applications in various industries. This thesis addresses a specific instance of the this problem, known as the Container Packing problem. Special attention is paid to the Pallet Loading ... 
Builtin tests for a realtime embedded system.
(1991)Beneath the facade of the applications code of a welldesigned realtime embedded system lies intrinsic firmware that facilitates a fast and effective means of detecting and diagnosing inevitable hardware failures. These ... 
A practical investigation of meteorburst communications.
(1991)This study considers the meteorburst communication (MBC) environment at three levels. At the lowest level, the trails themselves are studied and analysed. Then individual links are studied in order to determine the data ... 
Speech recognition and blackboard expert systems.
(1992)Spoken language is used by people to communicate naturally with one another. A simplistic view of the communication process is as follows. Person A wishes to communicate an idea to person B. The idea, initiated in the ... 
Application of backpropagationlike generative algorithms to various problems.
(1992)Artificial neural networks (ANNs) were originally inspired by networks of biological neurons and the interactions present in networks of these neurons. The recent revival of interest in ANNs has again focused attention ... 
Modelling with mathematica.
(1994)In this thesis a number of mathematical models are investigated with the aid of the modelling package Mathematica. Some of the models are of a mechanical nature and some of the models are laboratories that have been ... 
The investigation into an algorithm based on wavelet basis functions for the spatial and frequency decomposition of arbitrary signals.
(1994)The research was directed toward the viability of an O(n) algorithm which could decompose an arbitrary signal (sound, vibration etc.) into its timefrequency space. The well known Fourier Transform uses sine and cosine ... 
A support environment for the teaching of programming.
(1996)This thesis examines the effectiveness of a specially constructed computer based support environment for the teaching of computer programming to novice programmers. In order to achieve this, the following distinct ... 
The development of a behavioural video analysis system and a toolbox prototype.
(1996)Behavioural research studies often include a data acquisition process, during which subjects are observed, and the displayed behaviours recorded, and a subsequent analysis process, during which the observed behaviours ... 
Neural network assisted software engineered refractive fringe diagnostic of spherical shocks.
(1996)A shock is essentially a propagating variation in the pressure or density of a medium. If the medium is transparent, such as air, and the shock radially symmetric, the refractive fringe diagnostic can be used to examine ... 
Application of genetic algorithms to the travelling salesperson problem.
(1996)Genetic Algorithms (GAs) can be easily applied to many different problems since they make few assumptions about the application domain and perform relatively well. They can also be modified with some success for handling ... 
Artificial neural networks for image recognition : a study of feature extraction methods and an implementation for handwritten character recognition.
(1996)The use of computers for digital image recognition has become quite widespread. Applications include face recognition, handwriting interpretation and fmgerprint analysis. A feature vector whose dimension is much lower ... 
The application of computer technology in South African distance education.
(1996)The advent of online ComputerAssisted Instruction and Computer Mediated Communication may improve instruction and communication in distance education in South African universities. Online ComputerAssisted Instruction ... 
On case representation and indexing in a casebased reasoning system for waste management.
(1997)CaseBased Reasoning is a fairly new Artificial Intelligence technique which makes use of past experience as the basis for solving new problems. Typically, a casebased reasoning system stores actual past problems and ... 
The design and simulation of routing protocols for mobile ad hoc networks.
(2000)This thesis addresses a novel type of network known as a mobile ad hoc network. A mobile ad hoc network is a collection of entirely mobile nodes that can establish communication in the absence of any fixed infrastructu ... 
A real time, system independent, secure, Internet based auctioning system.
(2000)This thesis outlines the creation of a secure, real time, system independent, Internet based auctioning application. The system has been developed to meet the needs of today's stringent reqUirements on secure Internet ... 
Spectral techniques for roughness estimation.
(2001)Roughness is a relatively untouched field considering its significance to natural scientists. In this thesis mathematical techniques for measuring the roughness of signals are constructed and investigated. Both one ... 
Computer assisted education : design, development and evaluation.
(2001)Educational institutions throughout the world are increasingly facing classes of educationally, culturally and linguistically diverse student groups. At the same time economic constraints require these institutions to ... 
Computer simulation of the two body abrasive wear process.
(2002)New computer technologies are applied to the classical material engineering twobody abrasive wear process. The computer simulation provides an interactive and visual representation of the wear process. The influence of ...
