  • Expert systems for management control: a multi-expert architecture 
    Ram, V (South African Computer Society (SAICSIT), 1991)
    The use of Expert Systems technology in management decision making domains is increasing rapidly as business environments worldwide grow more turbulent and as the cost of development tools decrease. Research effort in ...
  • Developing soft skills in computer students 
    Schroder, C; Thomas, T (2000)
    Today software developers are required to work closely with users when defining, developing and implementing systems. Interaction between software developers and users can influence the success or failure of the system ...
  • Modelling the algebra of weakest preconditions 
    Brink, C; Rewitzky, I (1991)
    Dijkstra's weakest precondition semantics, as presented in textbook form by Gries, may be viewed as an equational algebra. The problem then is to find a reasonable (set-theoric) model of this algebra. This paper provides one.
  • The effects of virtual banking on the South African banking industry 
    Dunley-Owen, M; Hart, ML (2000)
    The South African banking industry is set to undergo a complete transformation in the next ten years. One of the main reasons for this transformation is the development of virtual banking, specifically new delivery channels ...
  • Combining rule-based Artificial Intelligence with Geographic Information Systems to plan the physical layer of wireless networks in Greenfield areas 
    Prag, K; Premjeeth, P; Sandrasegaran, K (2000)
    This paper elucidates the development of a computer tool which combines the use of terrain data in a Geographic Information System (GIS), an equipment database and rule-based inference. It explores the use of GJS to aid ...
  • Information security awareness, a must for every organization 
    Thomson, M; Von Solms, R (2000)
    Information Technology (IT) has become part and parcel of the business world today. In fact, with the increasing sophistication of networks and the continued growth in electronic commerce, it will continue becoming an ever ...
  • PLaVa: a lightweight persistent Java virtual machine 
    Tjasink, S; Berman, S (2000)
    This paper describes the implementation and tuning of an orthogonally persistent Java Virtual Machine (JVM) for small computers. It is based on a JVM that was targeted at a digital satellite television decoder with 1 ...
  • Cardinality constrained 0-1 Knapsack problems 
    Kruger, MF; Hattingh, JM; Steyn, T (2000)
    The Knapsack Problem is one of the most important problems in Discrete optimization. Although it is the simplest integer program, it has numerous practical applications and often appears as a subproblem in solving more ...
  • Returns on the Stock Exchange 
    Kruger, JW (2000)
    The McGreggor database supplies the accounting information of companies listed on the Johannesburg stock exchange. These attributes are not significantly correlated to the Return. The Pearl's algorithm in Bayesian belief ...
  • Error analysis in selected medical devices and information systems 
    Randiki, E (1998)
    The purpose of this paper is to identify and analyse error in selected medical devices: the Datex cardiocap and the capnomac Ultima II. These are both anaesthetic machines used to monitor patients in theatre. A secondary ...
  • A risk model to allocate resources to different computerised systems 
    Kruger, HA; Hattingh, JM (1997)
    The majority of large organisations operate and maintain significant portfolios of computerised systems. All Information Systems (IS) managers are increasingly faced with the task of doing more with less. To cope with ...
  • Model checking software with symbolic trajectory evaluation 
    Hazelhurst, S (1997)
    Traditional methods of testing computer systems, although valuable, are inadequate for ensuring sufficiently high quality in systems in which a high degree of reliability must be placed. Formal methods for development of ...
  • An overview of the Internet services available in South Africa 
    Radovanovic, A; Venter, DM (1995)
    South African networking history started in the mid 1980's. Within less than ten years, the country became the 15-th fastest growing network within the lnternet community. Today, the South African network offers a variety ...
  • Rank-one update of Cholesky factorization 
    Ntlatlapa, N (1995)
    Symmetric positive definite matrices appear in most methods for Unconstrained Optimization. The method widely adopted for factoring these matrices is Cholesky Factorization. Furthermore, in Quassi-Newton methods for ...
  • The design of a 2D non-linear filter for digital image processing 
    Cloete, E (1995)
    A 1 D non-linear filter which is based on 'max-min' selectors is extended for use in 2 0 applications. The objective of this research is to remove impulsive noise without unduly changing original, valid data. Some examples ...
  • Higraphs: an overview of theory and application 
    Hillebrand, G (1995)
    This paper presents an overview of the established concepts of David Harel' s higraphs, to increase their visibility. Higraphs are a union of extended graph and extended set theory which allows the understandable definition ...
