  • Building a secure database using self-protecting objects 
    Olivier, MS; Von Solms, SH (1991)
    In current database systems the responsibility for enforcing security is often given to the various application programs. Even where the Database Management System (DBMS) does supply security mechanisms, a single application ...
  • A reusable kernel for the development of control software 
    Fouche, W; De Villiers, PJA (1991)
    A kernel has been developed which can be used to simplify the development of control software. It can be used to control several physical machines which are interconnected via a fast local area network. One or more virtual ...
  • Using statecharts to design and specify a direct-manipulation user interface 
    Van Zijl, L; Mitton, D (1991)
    Statecharts were developed by Harel et al [10] to specify complex reactive systems. In this paper we report on our application of statecharts as a design and specification tool for an X-Windows based Graphical User ...
  • A new algorithm for finding an upper bound of the genus of a graph 
    Carson, DI; Oellermann, OR (1991)
    In this paper we discuss the problem of finding an upper bound on the genus of a graph. This problem has applications to circuit layouts. An electronic circuit may be modelled by a graph. By punching holes into the circuit ...
  • Expert systems for management control: a multi-expert architecture 
    Ram, V (South African Computer Society (SAICSIT), 1991)
    The use of Expert Systems technology in management decision making domains is increasing rapidly as business environments worldwide grow more turbulent and as the cost of development tools decrease. Research effort in ...
  • An overview of the Internet services available in South Africa 
    Radovanovic, A; Venter, DM (1995)
    South African networking history started in the mid 1980's. Within less than ten years, the country became the 15-th fastest growing network within the lnternet community. Today, the South African network offers a variety ...
  • Rank-one update of Cholesky factorization 
    Ntlatlapa, N (1995)
    Symmetric positive definite matrices appear in most methods for Unconstrained Optimization. The method widely adopted for factoring these matrices is Cholesky Factorization. Furthermore, in Quassi-Newton methods for ...
  • Business computing: an African perspective 
    Blewett, CN; Erwin, GJ (1995)
    The book uses storytelling as teaching, with exclusive use of active tense, local examples a problem-driven approach rather than a product-driven approach. For example, magnetic tape principles are explained in ...
  • An alternative teaching approach for information systems 
    De Villiers, C; Roode, JD (1995)
    lnterpersonal skills and communications are the two topics in Curriculum '95, compiled by the joint task force of the ACM/AIS-ICIS/DPMA, where both academics and industry expect the level of knowledge of the students to ...
  • Object-oriented development: knowledge base support for design 
    Loock, M; Steenkamp, AL (1995)
    The research is conducted in the area of Software Engineering, with emphasis on the design phase of the Software Development Life Cycle (SDLC). The object-oriented paradigm is the point of departure. The investigation deals ...
  • New directions in research on information requirements analysis: the language connection 
    Klein, HK; Truex, DP (1995)
    This paper outlines the basic theoretical assumptions of language analysis and then proposed a new approach called discourse analysis. The theoretical foundations of discourse analysis are Wittgenstein's theory of language ...
  • A method to generate occam skeletons from formal specifications 
    Ikram, IM (1995)
    We consider the problem of automatically generating parallel programs in the occam language. In particular, we are concerned with the generation of program skeletons, that define just those computations that are common ...
  • Rethinking IS Curricula for South Africa 
    Froneman, L; Roode, JD (1995)
    What to teach students in an undergraduate program in Information Systems at a tertiary institution has repeatedly been debated over the years. Various curricula have been published, the most recent effort being the IS ...
  • Options for development cooperation in IT education and training: the Zimbabwe case 
    Sithole, AS (1995)
    This paper attempts to address the need and justification for a Computer Skills Requirements Model for Zimbabwe as well as the findings and plans following the recently completed Zimbabwe Computer Industry Manpower Survey. ...
  • A writing support tool for distance students 
    Barrow, J (1995)
    This paper describes SuperText, a computer program designed to support productive expository writing processes among students at a distance teaching university. Being able to write well is an import communication skill, ...
  • A case-based reasoning approach to intelligent retrieval in reusable software libraries 
    Ram, V (1995)
    Software Reuse is the technique of reusing software components previously developed in order to reduce the effort required to develop new software. It is generally accepted that software reuse can improve the rate of ...
  • Development of a compiler construction toolkit for an introductory course in compiling 
    Ganchev, GF (1995)
    The compiler construction toolkit under development in the University of Botswana (UB is intended to allow the students build rapidly components of compilers for languages that they define. It consists of a case-type scanner ...
  • Investigation of timetabling in tertiary institutions in Southern Africa 
    Nepal, T; Melville, S (1995)
    This paper deals with approaches to the timetabling problem, focusing on tertiary institutions in Southern Africa. A questionnaire which dealt with, inter alia, student population, number of class groups, methods used for ...
  • Towards an option space for network structures in computer-based instruction 
    Kotze, P (1995)
    There are three major agents in a computer-based instruction (CBI) environment: the tutor, the tutoring system and the tutee. The emphasis of this paper is on the tutoring system which contains the instructional content ...
  • The application of scripts to deadlock avoidance 
    Blewett, CN; Erwin, GJ (1995)
    We describe the prototype of an expert system software advisor for the lock manager of a database system. The software advisor, called EAGLE (Expert Advisor for Granting Locks Effectively), is intended to become an ...
