  • 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 ...
  • Statistical modelling of return on capital employed of individual units 
    Burombo, Emmanuel Chamunorwa (2014-10)
    Return on Capital Employed (ROCE) is a popular financial instrument and communication tool for the appraisal of companies. Often, companies management and other practitioners use untested rules and behavioural approach ...
  • A strategic model for planning and implementing an on-line approach for continuous professional development 
    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 ...
  • Structural equation modelling 
    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 ...
  • A study on the analysis of two-unit redundant repairable complex systems 
    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 ...
  • Sublocale-based ideals of rings of integer-valued functions 
    Tlharesakgosi, Batsile (2021-07)
    Let L be a zero-dimensional frame and ZL be the ring of continuous integer-valued functions on L. We associate with each sublocale of L, the Banaschewski compacti cation of L, an ideal of ZL, and study the behaviour of ...
  • Sums and products of square-zero matrices 
    Hattingh, Christiaan Johannes (2018-03)
    Which matrices can be written as sums or products of square-zero matrices? This question is the central premise of this dissertation. Over the past 25 years a signi - cant body of research on products and linear combinations ...
  • Supplementary tuition in Mathematics: exploring the industry in the Eastern Cape 
    Coetzee, J. (2009-08-25)
    This study explored and evaluated the prevalence of supplementary tuition in the teaching and learning of Mathematics/Mathematical Literacy in some high-performing schools of the East London district in the Eastern Cape. ...
  • Teachers' views on the use of contexts in transition to mathematics 
    Phoshoko, Moshe Moses (2013-05-)
    The exploratory study sought to elicit and document mathematics teachers‟ views on how they enacted the process of transition between contexts and mathematics. The study pursued to understand teachers‟ beliefs and knowledge ...
  • Tidal distortion of a neutron star in the vicinity of a black hole 
    Naidoo, Monogaran (2009-08-25)
    We will consider the scenario of the co-rotation of a fluid star (in specific, a neutron star) and a black hole. The neutron star (or primary)is assumed to have constant angular velocity. The tidal effects on the primary ...
  • Topics on z-ideals of commutative rings 
    Tlharesakgosi, Batsile (2017-08)
    The first few chapters of the dissertation will catalogue what is known regarding z-ideals in commutative rings with identity. Some special attention will be paid to z-ideals in function rings to show how the presence ...
  • Towards hybrid stochastic modeling and simulation of complex systems in multi-scale environments with case studies on the spread of tuberculosis in Democratic Republic of the Congo 
    Kabunga, Selain Kasereka (2020-10)
    Mathematical modeling of the spread of infectious diseases in a population has always been recognized as a powerful tool that can help decision-makers understand how a disease evolves over time. With the evolution of science ...
  • Triple generations of the Lyons sporadic simple group 
    Motalane, Malebogo John (2015-03)
    The Lyons group denoted by Ly is a Sporadic Simple Group of order 51765179004000000 = 28 37 56 7 11 31 37 67. It(Ly) has a trivial Schur Multiplier and a trivial Outer Automorphism Group. Its maximal subgroups are G2(5) ...
  • Two conjectures on 3-domination critical graphs 
    Moodley, Lohini (1999-01)
    For a graph G = (V (G), E (G)), a set S ~ V (G) dominates G if each vertex in V (G) \S is adjacent to a vertex in S. The domination number I (G) (independent domination number i (G)) of G is the minimum cardinality ...
