  • Some automata-theoretic properties of -NFA 
    Van Zijl, L; Van der Walt, APJ (South African Computer Society (SAICSIT), 1999)
    We prove that the shortest word accepted by an n-state intersection selective nondeterministic automaton with nonempty language can be of length O( e n log n).
  • Some current practices in evaluating IT benefits in South African organisations 
    Sutherland, F (South African Computer Society (SAICSIT), 1994)
    IT has a dynamic impact on organisations and little research has been done especially on the extent to which senior executives take the different system types into account when they appraise an IT investment. The aim of ...
  • Some typical phases of a business transformation project 
    Remenyi, D (South African Computer Society (SAICSIT), 1997)
    Business Process Reengineering (BPR) or Business Transformation is very difficult to manage successfully. There is a high failure rate of BPR projects and thus the risk associated with this type of work is high. Although ...
  • South African Computer Journal Table of Contents 
    Unknown author (2019)
  • Specialization by exclusion 
    Theron, H; Cloete, I (South African Computer Society (SAICSIT), 1994)
    This paper presents a theoretical analysis of the search schemes employed by AQ, CN2 and the recently introduced BEXA algorithm. These covering algorithms induce disjunctive concept descriptions, and employ a general-to-specific ...
  • Specific acquisition of collective belief knowledge for socially motivated multiagent systems 
    Ram, V (South African Computer Society (SAICSIT), 1998)
    Shared beliefs and knowledge are an integral part of an organisation's identity and a prerequisite for collective func­tioning. Multiagent systems that support or emulate cooperative problem solving in such a context cannot ...
  • SSDE: CASE in education 
    Norman, MJ; Berman, Sonia (South African Computer Society (SAICSIT), 1993)
    Software Engineering is a difficult and time-consuming discipline to learn. CASE Tools are generally expensive, prescriptive and tedious to use. Structured Software Development Environment (SSDE) was developed as a teaching ...
  • Statenets - an alternative modelling mechanism for performance analysis 
    Lewis, L (South African Computer Society (SAICSIT), 1992)
    Statecharts were developed by Harel to specify complex reactive systems. Statecharts proved to be rich in modelling power and convenience [9] and well suited to mechanical implementation. However, the semantic definition ...
  • Statistical analysis of an automated computer architecture learning environment 
    Waldron, JT; Horgan, J; Keogh, G (South African Computer Society (SAICSIT), 1999)
    The level of programming skill achieved by a method of learning introductory computer architecture with a strong emphasis on assembly language programming as part of a Graduate Diploma in Information Technology in the ...
  • 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 survey of information authentication techniques 
    Smuts, WB (South African Computer Society (SAICSIT), 1994)
    This article provides a survey of techniques which can be used to add authenticity to electronic documents and messages.
  • Syntactic description of neighbourhood in quadtree 
    Tapamo, JR (South African Computer Society (SAICSIT), 2000)
    Region representation is very important in Graphics and Image Processing. This paper is concerned with a formalisation of image representation by quadtrees. Indeed an image here is a language over an alphabet of four ...
  • Teaching math more effectively, through the design of calculational proofs 
    Gries, D; Schneider, FB (South African Computer Society (SAICSIT), 1998)
  • Teaching Pascal using multimedia 
    Jordaan, DB; Gilliland, S (South African Computer Society (SAICSIT), 1994)
    Research has shown that traditional teaching methods such as lecturing are not always as effective as the teacher or lecturer might like them to be. Frederick [3, p45] stated: 'Nearly all learning theorists.faculty development ...
  • 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 ...
