    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes a study of changes in attitude toward computers exhibited by novice student users during a first course in business computing. Several dimensions of attitude were established by factor analysis. ...
  • Design of secure medical database systems 
    Pangalos, G; Khair, M (South African Computer Society (SAICSIT), 1996)
    A database design methodology is presented in this paper which aims to improve the security of medical database systems. The proposed methodology is based on both the discretionary and the mandatory database security ...
  • Random context structure grammars 
    Ehlers, E.M.; von Solms, S. H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Random Context Structure Grammars are defined. The language generated by a Random Context Structure Grammar is a set of three-dimensional digital structures. A hierarchy of Random Context Grammars is discussed briefly. ...
  • Hands-on microprogramming for computer science students 
    Clayton, Peter G. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper advocates hands-on training on microprogrammable hardware for Computer Science students, and suggests an appropriate microprogram development approach for this purpose. The particular tool discussed is ...
  • Functional and operational security system for open distributed environments 
    Muftic, S (South African Computer Society (SAICSIT), 1996)
    The paper describes the design details and implementation results of the completely integrated, functional and operational security system, suitable for open distributed environments. Functionality means that security ...
  • Encryption policy for the global information infrastructure 
    Hoffman, LJ (South African Computer Society (SAICSIT), 1996)
    Cryptology policy deals not only with various technological encryption methods but also with thorny political and adminis­trative problems. It is a challenge to address these in a timely and open manner. The problems arise ...
  • Reinforcing password authentication with typing biometrics 
    De Ru, WG; Eloff, JHP (South African Computer Society (SAICSIT), 1996)
    This paper presents a methodology for the reinforcement of password authentication with the use of typing biometrical mechanisms. Typing biometrics refers to the analysis of keystroke patterns, which is unique for each ...
  • User attitudes main reason why information systems fail 
    Bruwer, P.J.S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Some factors which may influence the attitude of the user toward a computerized system are investigated in this article. The research was done in South Africa involving the users of computer-based systems in two organizations. ...
  • A CAI model of space and time with special reference to field battles 
    Anderssen, E.C.; von Solms, S. H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A computer aided instruction facility is presented, in which the simulation of field battles introduces history students to the dynamic relationships between space and time in a historical perspective. Information on a ...
  • The development of a syntax checker for LOTOS 
    Van der Vegte, L.J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    In this article a brief overview is given of specification techniques in general and in particular, specification techniques used for the specification of communication protocols. This discussion forms the background ...

    Roos, Jan (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    ESTELLE is being developed by the International Standards Organisation (ISO), Technical Committee (TC) 97, Sub-committee (SC) 21, Working Group (WG) 1, Formal Definition Technique (FDT) Subgroup B to fulfil the need for ...
  • Decision tables as a knowledge representation formalism 
    Podevyn, D. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A knowledge engineering tool called GESS (General Expert System Shell) is presented which is used for building different types of expert systems. Knowledge representation is based on direct extensions of the idea of decision ...
  • Research computeracy 
    Pirow, Peter Cluver (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes the concept of computeracy as it applies to research workers and argues that research will be improved if the level of computeracy can be raised.
  • Education rather than training 
    Levieux, Craig (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The role of teachers in a University Computer Science course is examined. The case for education rather than training is put. It is argued that current methods of teaching are not as effective as they could be. A case ...
  • Local area networks in perspective 
    Kritzinger, Pieter S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Current scientific and trade literature are flooded with information about local area networks. Details about physical media and their properties, versions of media access methods confusingly called protocols, variations ...
  • Experience with teaching software engineering 
    Hoogendoorn, C.H. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The term "software engineering" has been in use for nearly 20 years since the so-called "software crisis" was identified in the late 1960's. However, it is only comparatively recently that courses in software engineering ...
