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 ... 
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 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 ... 
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 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 ... 
The application of multistate Markov models to HIV disease progression.
(2011)Survival analysis is a well developed area which explores time to single event analysis. In some cases, however, such methods may not adequately capture the disease process as the disease progression may involve ... 

Application of statistical multivariate techniques to wood quality data.
(2010)Sappi is one of the leading producer and supplier of Eucalyptus pulp to the world market. It is also a great contributor to South Africa economy in terms of employment opportunity to the rural people through its large ... 
Application of survival analysis methods to study underfive child mortality in Uganda.
(20131212)Infant and child mortality rates are one of the health indicators in a given community or country. It is the fourth millennium development goal that by 2015, all the united nations member countries are expected to have ... 
The application of the unified modelling language and soft systems metholdology for modelling the production process in an aluminium plant.
(2003)This research explores the combined use of soft systems methodology (SSM) and UML based business process modelling (BPM) techniques. These two techniques are integrated to provide a framework for the analysis and definition ...
