  • Pointers as a data type 
    Philips, N.C.K.; Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The distinction between an abstract data type and an implementation of a data type is not as clear as is commonly thought. A hash table can be used to implement the type bag but few of our colleagues think of a hash table ...
  • Common approach to some informational systems 
    Orlowska, M.E. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    In this paper we consider relationships between a complete system [6], an L-system [3], a stochastic system [13] and an N-system [8]. We introduce a notion of the induction of one system by another. We prove the important ...
  • Three packaging rules for information system design 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    After identifying the processing functions required in a computer based information system, the designer needs to combine them into an optimal set of load units. Some "packaging" arrangements yield a better system ...
  • The ELSIM language: an FSM-based language for the ELSIM SEE 
    Du Plessis, A.L.; Bornman, C.H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A fonnal requirements specification language, the ELSIM language, is presented. The language uses conceptual models for modelling data processing, and control characteristics and behavior of real-time systems, and is ...
  • A comparison of academic and practitioner perceptions of the changing role of the systems analyst: an empirical study 
    Crossman, T.D. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Changes in technology introduce new job responsibilities and demand new skills profiles from personnel involved in application software development. Inability to perfonn competently within these job responsibilities can ...
  • Strategic planning models for information systems 
    Bruwer, P.J.S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A key to the success of the information system function in organizations is a comprehensive, effective planning system. According to R.V. Head's[l] pyramid structure of an Information system managers are classified into ...
  • A model to evaluate the success of information centres in organizations 
    Bruwer, P.J.S.; Groenewald, J.J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The objective of this research report was to investigate some South African organizations who have been operating information centres (IC's) successfully for more than two years. As the success of the IC is strongly · ...
  • Abstracts of Old mutual conference for Ph.D and M.Sc students In Computer Science, Stellenbosch, 2-3 October 1987 
    Unknown author (Computer Society of South Africa (on behalf of SAICSIT), 1987)
  • 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, ...
  • The practice of clausification in automatic theorem proving 
    Sutcliffe, G; Melville, S (South African Computer Society (SAICSIT), 1996)
    In the process of resolution based Automatic Theorem Proving, problems expressed in First Order Form (FOF) are transformed by a clausifier to Clause Normal Form (CNF). This research examines and compares clausifiers. ...
  • The new IS'95 curriculum 
    Smith, DC (South African Computer Society (SAICSIT), 1996)
    The recent acceptance of South Africa as a world player and the government's reconstruction and development programme (RDP) have created new challenges and opportunities for business and universities. The Information Systems ...
  • Business process reengineering: A down to earth critique 
    Shewaram, T (South African Computer Society (SAICSIT), 1996)
    'Change' is a universal phenomenon that many take for granted. Without change, time has no meaning. Even people are essentially dynamic processes, we are constantly changing in multitudinous ways. In light of this, it is ...
  • An AI search algorithm to obtain the shortest simplex path 
    Scott, TG; Hattingh, J.M.; Steyn, T (South African Computer Society (SAICSIT), 1996)
    The simplex method is one way of solving a linear programming problem (LP-problem). An A* search algorithm based on a certain evaluation function has been developed to obtain the shortest path to an optimal solution within ...
  • An integrated classification of multiple database systems 
    Renaud, K; Kotze, P (South African Computer Society (SAICSIT), 1996)
    In many applications today multiple pre-existing database systems are integrated into one multiple database system. There are various characteristics of these systems which distinguish them from other types of multiple ...
  • The homological transfer research method revisited 
    Koornhof, C (South African Computer Society (SAICSIT), 1996)
    The Homological transfer method is a very efficient research method which is based on similarities between manufacturing, financial, educational, informational and other productive processes. The existence of these ...
  • The complexity of Petri Net transformations 
    Donaldson, SR; Bause, F; Kritzinger, Pieter S. (South African Computer Society (SAICSIT), 1996)
    We consider the complexity of several property preserving Petri net transformations found in the literature. These transfor­mations were candidates for.inclusion in a software tool to peiform liveness and boundedness ...
  • Critical success factors for implementing CASE at a selection of companies in South Africa 
    Addison, TM; Hamersma, S (South African Computer Society (SAICSIT), 1996)
    CASE, or Computer Assisted Software Engineering, provides the potential for a future in which computer programs will be generated automatically from business rules, but many potential buyers have adopted a wait and see ...
  • Rekenaar spraaksintese: die omskakeling van teks na klank 
    Wagener, M.J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Verslag word gelewer oor die ontwikkeling en implementering van 'n stel letter-na-klank reels vir die omskakeling van Afrikaanse teks na foneme. 'n Inleidende oorsig van rekenaar spraaksintese en 'n kort beskrywing van ...
  • Polygon shading on vector type devices 
    Scheepers, C.F. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A method is presented whereby the interior of boundary-defined regions on vector type devices may be shaded using regular line, cross-hatch and dot patterns. Different shades are realized by changing shading parameters ...
  • Set-oriented functional style of programming 
    Mueller, C.S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A novel way of programming, which starts with specific details of a particular example and abstracts these details into generalised sets, is proposed. The whole program is constructed around the definition of these ...
