Knowledgedirected intelligent information retrieval for research funding.
(2001)Researchers have always found difficulty in attaining funding from the National Research Foundation (NRF) for new research interests. The field of Artificial Intelligence (AI) holds the promise of improving the matching ... 
Learners' conceptual understanding of congruent triangles in transformation geometry
(2011)No abstract. 
Locally finite nearness frames.
(1998)The concept of a frame was introduced in the midsixties by Dowker and Papert. Since then frames have been extensively studied by several authors, including Banaschewski, Pultr and Baboolal to mention a few. The idea of ... 
Long time behaviour of population models.
(2010)Nonnegative matrices arise naturally in population models. In this thesis, we look at the theory of such matrices and we study the PerronFrobenius type theorems regarding their spectral properties. We use these theorems ... 
Mathematical analysis of preexposure prophylaxis on HIV infection.
(2012)We develop a mathematical model which seeks to assess the impact of HIV PreExposure Prophylaxis (PrEP) on the prevalence and incidence of HIV infection. Mathematical analysis of the model is carried out to establish the ... 
Mathematical analysis of tuberculosis vaccine models and control stategies.
(20141020)The epidemiological study of tuberculosis (TB) has been ongoing for several decades, but the most effective control strategy is yet to be completely understood. The basic reproduction number, R₀, has been found to be ... 
Mathematical attitudes and achievement strategies of successful mathematics learners.
(2011)Too often, discussions about Mathematics express feelings of anguish and despair; and, indeed Mathematics results in general in South Africa can be described as dismal. The Department of Education (DoE) reported that in ... 
Mathematical modelling of drug resistance in malignant tumour treatment.
(2014)Resistance to conventional chemotherapies, especially to anticancer agents, is rapidly becoming a global pandemic. Mutations, in combination with genetic instabilities, play an important role in the molecular heterogeneity ... 
Maths anxiety and communication apprehension as barriers to learning mathematics.
(2011)As learners progress through the educational system their interest in mathematics diminishes. Although mathematics is designed to challenge learners, it has produced a high number of failures. Mathematics is most often ... 
A measuretheoretic approach to chaotic dynamical systems.
(2001)The past few years have witnessed a growth in the study of the longtime behaviour of physical, biological and economic systems using measuretheoretic and probabilistic methods. In this dissertation we present a study of ... 
Modeling the burden of disease for cattle.
(2014)Summary measures of human population health (SMPH) represents approaches to measuring the burden of disease. These approaches are divided into two classes: health expectancies and health gaps. A health gap model approach ... 
Modelling the spatial dynamics of a semiarid grazing system.
(1999)A large proportion of the world's land surface is covered by semiarid grasslands, and they provide an important source of income as a grazing resource. A more comprehensive understanding of these complex ecosystems is ... 
Multiparameter perturbation analysis of a second grade fluid flow past an oscillating infinite plate.
(2009)In this dissertation we consider the two dimensional flow of an incompressible and electrically conducting second grade fluid past a vertical porous plate with constant suction. The flow is permeated by a uniform transverse ... 
On decoupled quasilinearization methods for solving systems of nonlinear boundary value problems.
(20150610)In this dissertation, a comparative study is carried out on three spectral based numerical methods which are the spectral quasilinearization method (SQLM), the spectral relaxation method (SRM) and the spectral local ... 
On minimal degrees of faithful permutation representations of finite groups.
(2014)Abstract available in PDF file. 
On spectral torsion theories.
(2003)The purpose of this thesis is to investigate how "spect ralness" properties of a torsion theory T on R  Mod are reflected by properties of the ring R and its ring of quotients R,.. The development of "spectral" torsion ... 
On the existence of selfdual codes invariant under permutation groups.
(2014)Abstract available in PDF file. 
An overview of hidden symmetries.
(2012)Approaches to nding solutions to di erential equations are usually ad hoc. One of the more successful methods is that of group theory, due to Sophus Lie. In the case of ordinary di erential equations, the subsequent ... 
Population dynamics based on the McKendrickvon Foerster model.
(1988)The current state of information concerning the classical model of deterministic, agedependent population dynamics  the McKendrick von Foerster equation  is overviewed. This model and the related Renewal equation are ... 
The preliminary group classification of the equation utt = f(x,ux)uxx + g(x, ux)
(1995)We study the class of partial differential equations Utt = f(x, ux)uxx + g(x, u x), with arbitrary functions f(x, u x) and g(x, u x), from the point of view of group classification. The principal Lie algebra of infinitesimal ...
