  • On completeness of partial metric spaces, symmetric spaces and some fixed point results 
    Moshokoa, Seithuti Philemon; Aphane, Maggie (2016-12)
    The purpose of the thesis is to study completeness of abstract spaces. In particular, we study completeness in partial metric spaces, partial metric type spaces, dislocated metric spaces, dislocated metric type spaces ...
  • On factorization structures, denseness, separation and relatively compact objects 
    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 ...
  • On some results of analysis in metric spaces and fuzzy metric spaces 
    Aphane, Maggie (2009-12)
    The notion of a fuzzy metric space due to George and Veeramani has many advantages in analysis since many notions and results from classical metric space theory can be extended and generalized to the setting of fuzzy ...
  • The predictors of success of computer aided learning of pre-calculus algebra 
    Yushau, Balarabe (2009-08-25)
    Mathematics achievement has been of great concern to researchers involved in mathematics education. This concern has resulted in research seeking to determine for example, the factors that positively or negatively contribute ...
  • Pricing European and American bond options under the Hull-White extended Vasicek Model 
    Mpanda, Marc Mukendi (2013-01)
    In this dissertation, we consider the Hull-White term structure problem with the boundary value condition given as the payoff of a European bond option. We restrict ourselves to the case where the parameters of the Hull-White ...
  • Pricing outside barrier options when the monitoring of the barrier starts at a hitting time 
    Mofokeng, Jacob Moletsane (2015-02)
    This dissertation studies the pricing of Outside barrier call options, when their activation starts at a hitting time. The pricing of Outside barrier options when their activation starts at time zero, and the pricing of ...
  • Products of diagonalizable matrices 
    Khoury, Maroun Clive (2002-09)
    Chapter 1 reviews better-known factorization theorems of a square matrix. For example, a square matrix over a field can be expressed as a product of two symmetric matrices; thus square matrices over real numbers can be ...

  • The queen's domination problem 
    Burger, Alewyn Petrus (1998-11)
    The queens graph Qn has the squares of then x n chessboard as its vertices; two squares are adjacent if they are in the same row, column or diagonal. A set D of squares of Qn is a dominating set for Qn if every square ...
  • Radio astronomy techniques : the use of radio instruments from single dish radio telescopes to radio interferometers 
    De Witt, Aletha (2012-03)
    New radio telescopes under development, will significantly enhance the capabilities of radio astronomy in the Southern Hemisphere. South Africa, in particular, is actively involved in the development of a new array ...
  • Remoteness in the category of locales 
    Nxumalo, Mbekezeli Sibahle (2023-05)
    This thesis is concerned with the study of remote sublocales which are a pointfree version of remote subsets which we de ne using van Mill's de nition of a remote collection. Unlike in van Mill's case though, the remote ...
  • Risk properties and parameter estimation on mean reversion and Garch models 
    Sypkens, Roelf (2010-09)
    Most of the notations and terminological conventions used in this thesis are Statistical. The aim in risk management is to describe the risk factors present in time series. In order to group these risk factors, one needs ...
  • The role of the pedagogical content knowledge in the learning of quadratic functions 
    Ibeawuchi, Emmanuel Ositadinma (2010-06)
    This study investigates to what extent educators’ pedagogical content knowledge affects learners’ achievement in quadratic functions. The components of pedagogical content knowledge (PCK) examined are: (i) mathematical ...
  • A simulation study of the effect of therapeutic horseback riding : a logistic regression approach 
    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 ...
  • Solving multiobjective mathematical programming problems with fixed and fuzzy coefficients 
    Ruzibiza, Stanislas Sakera (2011-04)
    Many concrete problems, ranging from Portfolio selection to Water resource management, may be cast into a multiobjective programming framework. The simplistic way of superseding blindly conflictual goals by one objective ...
  • Some stochastic problems in reliability and inventory 
    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 ...
  • Spectral factorization of matrices 
    Gaoseb, Frans Otto (2020-06)
    The research will analyze and compare the current research on the spectral factorization of non-singular and singular matrices. We show that a nonsingular non-scalar matrix A can be written as a product A = BC where the ...
  • Stable matching in preference relationships 
    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 ...
  • Static and dynamic traversable wormholes 
    Adamiak, Jaroslaw Pawel (2009-08-25)
    The aim of this work is to discuss the effects found in static and dynamic wormholes that occur as a solution of Einstein equations in general relativity. The ground is prepared by presentation of "faster than light" ...
  • Statistical modelling by neural networks 
    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 ...
