  • Siweya, Hlengani James (1994-04)
    We define morphism (E, M)-structures in an abstract category, develop their basic properties and present some examples. We also consider the existence of such factorization structures, and find conditions under which they ...
  • Van Heerden, Liske (1994-11-30)
    The unique problems encountered when analyzing weather data sets - that is, measurements taken while conducting a meteorological experiment- have forced statisticians to reconsider the conventional analysis methods and ...
  • Thulapersad, Sarah (1994-12)
    In the paper [HSS] Herrlich, Salicrup and Strecker were able to show that Kuratowski / Mrowka's Theorem concerning compactness for topological spaces could be applied to a wider setting. In this dissertation, which is based ...
  • Hildebrand, Annelize (1995-11)
    In developing an understanding of real-world problems, researchers develop mathematical and statistical models. Various model selection methods exist which can be used to obtain a mathematical model that best describes ...
  • Schoeman, Daniel Frederik (1996-06)
  • Mohanlal, Pramod (1997-06)
    Over the past two decades there has been an upsurge in interest in structural equation modelling (SEM). Applications abound in the social sciences and econometrics, but the use of this multivariate technique is not so ...
  • Taljaard, Monica (1997-06)
    Non-response is an error common to most surveys. In this dissertation, the error of non-response is described in terms of its sources and its contribution to the Mean Square Error of survey estimates. Various response and ...
  • Mohoto, Seth Themba (1998-06)
    Two well-known methods of improving the reliability of a system are (i) provision of redundant units, and (ii) repair maintenance. In a redundant system more units made available for performing the system function when ...
  • Pauw, Jeanette (1998-11)
    Therapeutic horseback riding (THR) uses the horse as a therapeutic apparatus in physical and psychological therapy. This dissertation suggests a more appropriate technique for measuring the effect of THR. A research ...
  • Busetti, Franco Raoul (2000-06)
    In this thesis we investigate the application of two heuristic methods, genetic algorithms and tabu/scatter search, to the optimisation of realistic portfolios. The model is based on the classical mean-variance approach, ...
  • Fletcher, Lizelle (2002-06)
    In this thesis the two disciplines of Statistics and Artificial Neural Networks are combined into an integrated study of a data set of a weather modification Experiment. An extensive literature study on artificial neural ...
  • Van der Merwe, Thomas Mc Donald (2008-06)
    The poor performance by South African pupils in The Third International Mathematics and Science Study highlighted the importance of and need for Continuing Professional Development (CPD) for South African mathematics ...
  • Chinemerem, Ikpe Dennis (2009-02)
    In this dissertation we obtain an e cient hybrid numerical method for the solution of stochastic di erential equations (SDEs). Speci cally, our method chooses between two numerical methods (Euler and Milstein) over a ...
  • Pilkington, Colin Leon (2009-08)
    Many learners find the study of introductory computer programming difficult. This is also true of children with attention deficit hyperactivity disorder (ADHD), and we need an improved understanding of how they learn ...
  • Potgieter, Paul (2009-08)
    After an introduction to Brownian motion, Hausdorff dimension, nonstandard analysis and Loeb measure theory, we explore the notion of a nonstandard formulation of Hausdorff dimension. By considering an adapted form of the ...
  • Schwartz, Larisa (2009-08-25)
    No abstract
  • Hargreaves, Carol Anne (2009-08-25)
    An attempt is made in this thesis to study some stochastic models of both reliability and inventory systems with reference to the following aspects: (i) the confidence limits with the introduction of common-cause ...
  • Faleye, Sunday (2009-08-25)
    It was generally accepted that the rate of formation of cerebrospinal °uid (CSF) is independent of intraventricular pressure [26], until A. Sahar and a host of other scientists challenged this belief. A. Sahar substantiated ...
  • Stols, Gert Hendrikus (2009-08-25)
    Real empowerment of school learners requires preparing them for the age of technology. This empowerment can be achieved by developing their higher-order thinking skills. This is clearly the intention of the proposed South ...
  • Philpin, Elizabeth Mary (2009-08-25)
    It is the aim of this paper to review some of the work done on stable matching, and on stable marriage problems in particular. Variants of the stable marriage problem will be considered, and the similarities and differences ...
