  • 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 ...
  • A new framework for information security to avoid information anarchy 
    Parker, DB (South African Computer Society (SAICSIT), 1996)
    It is reasoned that to preserve the three traditional elements of information security, confidentiality, integrity and availabil­ity, it is not sufficient to fully protect information. Three new elements are introduced: ...
  • A model for fault-tolerant computer systems 
    Goosen, H.A.; Hoogendoorn, C.H.; Goosen (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Reliability is an important consideration in the design of computer systems. This is a result of the increasing complexity of computer systems and of the greater reliance placed on their continuous and correct operation. ...
  • Information security on the electronic superhighway 
    Von Solms, SH (South African Computer Society (SAICSIT), 1996)
    This paper discusses a number of security protocols for the Internet and World Wide Web. The first two, SSL and SHTTP, provide general authentication, confidentiality and integrity facilities, while SEPP is a payment ...
  • Novice attitude changes during a first course In computing: a case study 
    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 ...
  • The protocol specification language ESTELLE 
    Roos, Jan (Computer Society of South Africa (on behalf of SAICSIT), 1987)
