  • Software design to meet third world requirements: an experimental software engineering approach 
    Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1989)
    Appropriate technology refers to technology appropriate for use in less developed parts of the world, especially the Third World; this paper raises some problems in adapting a definition of appropriate technology to ...
  • Some remarks on deleting a node from a binary tree 
    Aik-Koen, Heng (Computer Society of South Africa (on behalf of SAICSIT), 1986)
  • Specification and Performance Prediction of Fourth Generation Language Run Units 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Fourth generation languages offer substantial productivity benefits to data processing departments. Major problems associated with their use include the inability of conventional project management systems to control ...
  • 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 Structural Model of Information Systems Theory 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1988)
    The laws and techniques of maJure sub1ects such as Physics and Electrical Engineering are logically connected to one another in the form of a deductive network There is a foundation of basic laws deriving from them ...
  • A summation problem 
    Aik-Koen, Heng (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    This paper suggests a method to minimize the roundoff errors of adding N positive nimbers. The idea of construction can be easily applied to a linear recurrence process.
  • Syllabi for Computer Science as a Scientific Discipline 
    Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The paper is concerned with computer science as a science and the training required by its scientific practitioners-tobe. The background and objectives for a curriculum design are briefly sketched, and a taxonomy is given ...
  • Teacher Control in Computer-Assisted Instruction 
    Calingaert, Peter (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    To many persons, computer-assisted instruction (CAI) connotes automated programmed instruction (PI). This exemplifies the authorcontrolled mode of CAI, in which PI, suitably generalized, is mediated by the computer. This ...
