  • On learning styles and novice computer use 
    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Learning to use a decision support system involves both formal and informal teaching as well as self-teaching. Many cases have been documented of unsuccesful implementation of DSS or MIS in organisations and identifying ...
  • Semantic information management 
    Berman, Sonia (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    An information management system with a semantic data model interface is currently being developed at UCT. This system provides high-level, non-procedural access to information and enforces powerful integrity and security ...
  • The evaluation of business process reengineering projects in South Africa 
    Whittaker, L (South African Computer Society (SAICSIT), 1996)
    While much has been written describing the necessity for and effects of Business Process Reengineering (BPR), little research has been conducted into the evaluation of BPR projects. This paper describes the result of a ...
  • An approach for the standardisation of policies for selection of computer hardware and software 
    Petkov, D (South African Computer Society (SAICSIT), 1996)
    This paper suggests an approach for the selection of microcomputer equipment in a decentralised environment. It is based on a modification of the procedure of the Analytic Hierarchy Process (AHP) by T. Saaty. The structuring ...
  • Efficient shared memory multiprocessing and object-oriented programming 
    Machanick, Philip (South African Computer Society (SAICSIT), 1996)
    Object-oriented techniques are shown to hold promise for addressing the growing speed gap between memory and processors on shared-memory multiprocessors. However, reducing cache misses can be at the expense of more misses ...
  • ATM transmission convergence implementations: SONET/SDH vs Cell-based 
    De Jager, N; Roos, J (South African Computer Society (SAICSIT), 1996)
    This article discusses various issues around the Transmission Convergence (TC) sublayer in the physical layer of ATM. A brief introduction is given to the layered approach and functionality of the ATM physical layer. This ...
  • Reviewing IS curricula: A practical approach 
    Froneman, L; Roode, JD (South African Computer Society (SAICSIT), 1996)
    Many curriculum designs are based purely on what educators think it should be, reflecting their own experiences or idiosyn­crasies, with little reference to the needs of the information systems field. A number of studies ...
  • The status of computing manpower and training in tertiary education in Southern African universities 1995 
    Bishop, JM (South African Computer Society (SAICSIT), 1996)
    The survey of staff and student numbers done in 1992 provided the first country-wide picture of computing departments in South Africa. This report presents the picture three years later, from data collected in 1995. It ...
  • A comparison of graph colouring techniques 
    Parkinson, E; Warren, PR (South African Computer Society (SAICSIT), 1995)
    Many scheduling problems can be modelled as graph colouring problems. This paper gives a survey of heuristic algorithms used to colour graphs by describing a number of such algorithms found in the literature using an ...
  • The recall performance of multiple associative memories - a comparison of thresholding strategies 
    Vahed, A (South African Computer Society (SAICSIT), 1995)
    The associative network presents a practical and efficient means for the storage and retrieval of data. Although the recall abilities of single-layer associative memories have been well researched [3], little investigation ...
  • Enabling a collaborative approach to management 
    Tromp, PJ; Roode, JD (South African Computer Society (SAICSIT), 1995)
    In this paper the collaborative approach to management is examined and, in particular, how this approach could benefit from the right technological support. Collaborative management focuses on the joint performance of ...
  • Word frequencies in scientific prose 
    Paijmans, H (South African Computer Society (SAICSIT), 1995)
    An overview is given of popular term-weighting schemes as used in Information Retrieval. The question is raised whether the word frequency based t f.idf weights may be used as a yardstick to compare schemes that are not ...
  • Limitations and problems of management applications that use enterprise extensions to the SNMP MIB 
    Oosthuysen, WH; McDonald, T (South African Computer Society (SAICSIT), 1995)
    Until some years ago, management of TCP/IP based products was done in a proprietary fashion. Many large companies build their own system-wide management facilities because of a lack of usable systems to manage heterogeneous ...
  • Computer fraud in SA: an indictment of information systems 
    Messerschmidt, HJ (South African Computer Society (SAICSIT), 1995)
    There is an increasing amount of computer fraud in South Africa. A recent court case shows that Information Systems can actually assist criminals. The paper shows where the major loopholes are and suggests ways of improving ...
  • Training strategies for architecture-specific recurrent neural networks 
    Ludik, J; Cloete, I (South African Computer Society (SAICSIT), 1995)
    The typical approach taken by other researchers to address the defects of standard backpropagation is to investigate alternative methods for selecting initial parameter values, or for adjusting parameter values during BP ...
  • A high-level interface to a relational database System 
    Berman, Sonia; Walker, L. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    A high-level language for accessing a relational database is being developed at UCT. The system, known as HAL (High-level Access Language), provides complete data independence as users view the database in terms of ...
  • Parallel distributed objects' structure and their synchronization in an APPC environment 
    Kisimov, V; Da Silva, I (South African Computer Society (SAICSIT), 1995)
    Over a period of a few hours, every computer participating in a distributed system has many unused resources. If these resources can be combined, a large amount of computational power can be generated. This paper offers ...
  • A family tree of circumscriptive logics 
    Halland, KJ; Labuschagne, W.A. (South African Computer Society (SAICSIT), 1995)
    The relationships between the best-known forms of circumscription are elucidated with the aid of an hypothetical ancestor, which we choose to call naive circumscription.
  • In praise of solid state discs 
    Ridler, P.F. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    Various ways of using random access memory to emulate a magnetic disc storage system are described and the advantages and disadvantages are enumerated. An algorithm for making use of a solid state disc is given which avoids ...
  • The refinement calculus 
    Morgan, C (South African Computer Society (SAICSIT), 1995)
    The refinement calculus, based on weakest preconditions, elaborates imperative program developments as a series of steps linked by a mathematical refinement relation. Specifications and executable code are regarded equally ...
