  • Technological experience and technophobia in South African university students 
    Clarke, MC (South African Computer Society (SAICSIT), 2000)
    In an earlier study co-ordinated by Weil and Rosen, university students in 23 countries were surveyed in order to compare their levels of technological sophistication and technophobia. The countries sampled did not include ...
  • Test automation of safety-critical reactive systems 
    Peleska, J; Siegel, M (South African Computer Society (SAICSIT), 1997)
    This article focuses on test automation for safety-critical reactive systems. In the first part of the paper we introduce a methodology for specification, design and verification of fault-tolerant systems allowing to ...
  • Text categorization as an information retrieval task 
    Paijmans, H (South African Computer Society (SAICSIT), 1998)
    A number of methods for feature reduction and feature selection in text classification and information retrieval systems are compared. These include feature sets that are constructed by Latent Semantic Indexing, 'local ...
  • Theory meets practice. Using Smith's normalization in complex systems 
    Van der Merwe, AJ; Labuschagne, WA (South African Computer Society (SAICSIT), 1997)
    In 1985 Smith introduced a new way of deriving fully normalized tables. His method was based on the use of a dependency list and a dependency diagram to produce fifth normal form directly. We introduce the use of end-line, ...
  • 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 ...
  • Understanding HCI methodologies 
    Warren, P (South African Computer Society (SAICSIT), 1999)
    The paper proposes a framework for discussing methodologies for developing interactive computer systems. It uses this framework for a sample of systems and shows how certain insights about missing aspects of the methodologies ...
  • The universal relation as a database interface 
    Philips, M.J.; Berman, Sonia (South African Institute of Computer Scientists and Information Technologists, 1991)
    The universal relation is a way of overcoming users' prime database access difficulty, namely navigation through database structures. As a result there is reduced user involvement with the underlying logical database ...
  • An update on UNINET-ZA: The Southern African Academic and Research Network 
    Shaw, V (South African Institute of Computer Scientists and Information Technologists, 1991)
    The UNINET Academic and Research Network is a collaborative project among Universities, Research Councils and the FRD for the development, implementation and promotion of an academic and research network of computers ...
  • The use of a lattice for fast pattern matching 
    Oosthuizen, GD (South African Institute of Computer Scientists and Information Technologists, 1990)
    Pattern recognition involves the matching of a given pattern against a collection of patterns in store in order to identify the given pattern as belonging to a particular class already known to the system or not. Similarly, ...
  • Using information systems methodology to design an instructional system 
    O'Donovan, BC (South African Computer Society (SAICSIT), 1992)
    Designers of both computerized information systems and instructional systems are faced with a need to find more effective methods of identifying and supplying the information that the users of these systems require. Both ...
  • Using statecharts to design and specify a direct-manipulation user interface 
    Van Zijl, L; Mitton, D (South African Institute of Computer Scientists and Information Technologists, 1992)
    Statecharts were developed by Harel et al [10] to specify complex reactive systems. In this paper we report on our application of statecharts as a design and specification tool for an X-Windows based Graphical User Interface ...
  • Verification of finite state systems with temporal logic model checking 
    Schlingloff, B (South African Computer Society (SAICSIT), 1997)
    These tutorial notes contain an introduction to the logical theory and computational aspects of computer aided verification of finite state reactive systems with linear and branching temporal logic model checking. As a ...
  • Visualising eventuality structure 
    Rock, ST (South African Computer Society (SAICSIT), 1999)
    This paper describes the use of pictorial representations in showing the understanding of natural language that is about multiple or extended events. The focus is on the structure of such eventualities, and depiction of ...
  • What are websites used for - cost saving, revenue generating or value creating? 
    Lee, M (South African Computer Society (SAICSIT), 1999)
    For responding to the previous debate about whether Websites can be more properly used as a cost saving or revenue generating devices. The author interprets Plehan's internet selling matrix in a particular way to provide ...
  • What is information systems? 
    Crossman, T.D. (South African Computer Society (SAICSIT), 1994)
    This paper is an attempt to answer the question 'What is Information Systems?' While the characteristics of both a science and a non-science can be identified in Information Systems (IS), it is argued here that it is not ...
  • Where do software architectures come from? Systematic development from domains and requirements. A re-assessment of software engineering? 
    Bjorner, D (South African Computer Society (SAICSIT), 1998)
    In this paper we show how details of a software design emerges in two steps: software architecture and program organisation and from first having established careful descriptions of the application domain and of functional ...
  • Who will implement information technology for development? 
    Korpela, M (South African Computer Society (SAICSIT), 1995)
    There is a long, although thin, tradition of research on whether and how information technology (IT) can contribute to national development and basic human needs, particularly in developing countries (DCs). It is striking, ...
  • Why the fuss about neural networks? 
    Barth, G (South African Institute of Computer Scientists and Information Technologists, 1991)
    Currently, there is a certain hype about issues related to neural networks. This is somewhat surprising since the origins of neural nets date back some 40 years. At that time, several researchers experimented with distributed ...
