  • 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 ...
  • Prioritising data quality challenges in electronic healthcare systems in South Africa 
    Botha, Marna (2015-10)
    Data quality is one of many challenges experienced in electronic healthcare (e-health) services in South Africa. The collection of data with substandard data quality leads to inappropriate information for health and ...
  • Problem analysis using small problem frames 
    Jackson, MA (South African Computer Society (SAICSIT), 1998)
    The notion of a problem frame is introduced and explained, and its use in analysing and structuring problems is illustrated. A problem frame characterises a class of simple problem. Realistic problems are seen as compositions ...
  • Process simulation of the co-gasification of biomass and polythlene 
    Khumalo, Nomadlozi Lucy (2021-12)
    The aim of this study was to determine the effects of the feedstock composition, such as biomass, polyethylene and their respective blend ratios, -gasifying agents and operating conditions on the product gas composition, ...
  • Process synthesis and experimental analysis of waste tire thermochemical conversion processes 
    Mavukwana, Athi-Enkosi (2023-04-11)
    The thermochemical conversion of waste tires for chemicals and power production is investigated using process synthesis techniques and experimental analysis. Pyrolysis and gasification technologies were evaluated in terms ...
  • Product form solutions for multiserver centres with hierarchical concurrency constraints 
    Krzesinski, AE; Schassberger, R (1991)
    The MultiServer centre with Hierarchical Concurrency Constraints (MSHCC) is an exponential multiserver with a queueing discipline which imposes restrictions on the number of customers of different types and subtypes that ...
  • Production and characterization of biofuel from waste cooking 
    Emeji, Ikenna Chibuzor (2015-08)
    At present, the use of other sources of energy other than energy source from crude oil has accelerated. This is due to limited resources of fossil fuel, increasing prices of crude oil and environmental concerns. Alternative ...
  • The production of 103Pd and 109Cd using proton irradiated tandem natAg/natAg targets 
    Ineza, Claire (2015-03)
    103Pd is an important therapeutic radionuclide and has recently found great interest due to its higher radiobiologic effect. 109Cd decays by electron capture and is generally used as calibration sources in industrial and ...
  • 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 ...
  • Products of diagonalizable matrices 
    Khoury, Maroun Clive (2009-08-25)
    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 ...
  • Profiling mLearning students according to cultural dimensions : is that possible? 
    Van Biljon, Judy; Kotze, P. (SACLA, 2007-07-01)
    Mobile learning (mLearning) is a buzzword in education due to the widespread adoption and prolific use of mobile phones worldwide. Contextualisation, location and culturalisation are important issues in designing and ...
  • Program Design as the Tool of Preference in Computer Literacy Education, Experience, Incentives, Implications 
    Richfield, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Structured program design is urged as a rewarding vehicle for the introduction of computer concepts to age groups ranging from mid primary school to senior management. Progressively expanded subsets of the material form ...
  • A program development environment for microcomputers 
    Byron-Moore, S.P. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Any distractions in the working environment can affect the quality and quantity of output. For example, noise may disturb a person's thought processes and lead to errors. In addition, the programmer is subject to other, ...
  • Programme re-curriculation: An experience at the University of Johannesburg 
    Ramdass, Kemlall (International Journal of Business and Social Sciences., 2012-04-30)
    The clothing industry globally has undergone rapid change within the past few decades. The production of fashion has evolved into a multi faceted industry that is not only concerned with the manufacture of clothing but ...
  • Programming using induction 
    Mueller, C.S.M. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Induction has been used as a major tool in mathematics in proving theorems. This paper explores whether it has an equally important role in formulating programs. There are those who advocate that induction should be used ...
  • Progressing towards object orientation in South Africa 
    Jansen van Rensburg, M (South African Computer Society (SAICSIT), 1999)
    This article provides a description of the current state of Object Orientation in South African companies. It forms part of an MSc research report, looking at the pitfalls and guidelines in the transition to 00. The problems ...
  • Project management in CASE 
    Le Roux, M (1996)
