2generations pf the sporadic simple groups.
(1997)A group G is said to be 2generated if G = (x, y), for some nontrivial elements x, y E G. In this thesis we investigate three special types of 2generations of the sporadic simple groups. A group G is a (l, rn, n )generated ... 
Age structured models of mathematical epidemiology.
(20141121)We consider a mathematical model which describes the dynamics for the spread of a directly transmitted disease in an isolated population with age structure, in an invariant habitat, where all ... 
Algebraic properties of ordinary differential equations.
(1995)In Chapter One the theoretical basis for infinitesimal transformations is presented with particular emphasis on the central theme of this thesis which is the invariance of ordinary differential equations, and their first ... 
Analysis and numerical solutions of fragmentation equation with transport.
(20140512)Fragmentation equations occur naturally in many real world problems, see [ZM85, ZM86, HEL91, CEH91, HGEL96, SLLM00, Ban02, BL03, Ban04, BA06] and references therein. Mathematical study of these equations is mostly ... 
Analysis of a binary response : an application to entrepreneurship success in South Sudan.
(2012)Just over half (50:6%) of the population of South Sudan lives on less than one US Dollar a day. Three quarters of the population live below the poverty line (NBS, Poverty Report, 2010). Generally, effective government ... 
An analysis of approaches for developing national health information systems : a case study of two subSaharan African countries.
(2016)Health information systems in subSaharan African countries are currently characterized by significant fragmentation, duplication and limited interoperability. Incorporating these disparate systems into a coherent national ... 
Analysis of cultural and ideological values transmitted by university websites.
(2003)With the advent of globalisation and new communication technologies, it was inevitable that educational institutions would follow the advertising trend of establishing websites to market their services. This paper analyses ... 
Analysis of longitudinal binary data : an application to a disease process.
(2008)The analysis of longitudinal binary data can be undertaken using any of the three families of models namely, marginal, random effects and conditional models. Each family of models has its own respective merits and demerits. ... 
Analysis of mixed convection in an air filled square cavity.
(2010)A steady state twodimensional mixed convection problem in an air filled square unit cavity has been numerically investigated. Two different cases of heating are investigated and compared. In the first case, the bottom ... 
Analysis of multiple control strategies for preexposure prophylaxis and postinfection interventions on HIV infection.
(2016)Abstract available in PDF file. 
Analysis of shearfree spherically symmetric charged relativistic fluids.
(2011)We study the evolution of shearfree spherically symmetric charged fluids in general relativity. This requires the analysis of the coupled EinsteinMaxwell system of equations. Within this framework, the master field ... 
An analysis of symmetries and conservation laws of some classes of PDEs that arise in mathematical physics and biology.
(2016)In this thesis, the symmetry properties and the conservation laws for a number of wellknown PDEs which occur in certain areas of mathematical physics are studied. We focus on wave equations that arise in plasma physics, ... 
Analysis of timetoevent data including frailty modeling.
(2006)There are several methods of analysing timetoevent data. These include nonparametric approaches such as KaplanMeier estimation and parametric approaches such as regression modeling. Parametric regression modeling ... 
The applicability of casebased reasoning to software cost estimation.
(2002)The nature and competitiveness of the modern software development industry demands that software engineers be able to make accurate and consistent software cost estimates. Traditionally software cost estimates have been ... 
Application of artificial intelligence for detecting derived viruses.
(2017)A lot of new viruses are being created each and every day. However, some of these viruses are not completely new per se. Most of the supposedly ‘new’ viruses are not necessarily created from scratch with completely new ... 
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 ... 
The application of classification techniques in modelling credit risk.
(20150904)The aim of this dissertation is to examine the use of classification techniques to model credit risk through a practice known as credit scoring. In particular, the focus is on one parametric class of classification techniques ... 
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 ... 
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 ... 
Application of mixed model and spatial analysis methods in multienvironmental and agricultural field trials.
(2015)Agricultural experimentation involves selection of experimental materials, selection of experimental units, planning of experiments, and collection of relevant information, analysis and interpretation of the results. An ...
