  • High-level Debugging Systems for Pascal: Interpreter versus Compiler 
    Hirsch, Michael; Schach, Stephen R.; Van Biljon, Willem R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Two approaches to high-level debugging systems for Pascal are compared, namely the use of a debugging precompiler as against a debugging interpreter. A description is given of a high-level Pascal debugging interpreter ...
  • The universal relation as a database interface 
    Philips, M.J.; Berman, Sonia (South African Institute of Computer Scientists and Information Technologists, 1991)
    The universal relation is a way of overcoming users' prime database access difficulty, namely navigation through database structures. As a result there is reduced user involvement with the underlying logical database ...
  • Specification and Performance Prediction of Fourth Generation Language Run Units 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)

  • Software Configuration Management A practical approach 
    Du Preez, L.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A bnef description of software conf1gurat1on management principles 1s given, followed by a d1scuss1on on the ap pl1cat1on of these principles in a spec1f1c installation
  • 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 ...
  • An Adaptive Response Algorithm 
    Pirow, Peter (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    In five years of watching students operate terminals I have observed that the response time of the terminal has much to do with the comfort of the user. I have also observed this phenomenon in the business environment. ...
  • Migrations: A Microcomputer-Based Generalized Information Retrieval System 
    Pino, Jose A. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    This paper describes the design of MIGRATIONS, a software system under development at the University of Chile, whose purpose is to store, manage and retrieve unformatted text information. Among the most important design ...
  • Developing an Intelligent Editor for Microcomputers 
    McDermott, T.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A language-independent syntax-directed editor for teaching programming languages on micro-computers is briefly described. The design of the configuring grammar and the lnternal tree-structure to be edited and interpreted ...
  • On a Generalisation of Cayley Diagrams 
    Labuschagne, W.A.; Van Rooyen, H.O. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A technique for partially representing binary group operations by sets of binary relations was devised by Cayley. This technique can be generalised to permit the representation of arbitrary sets of n-ary relations {n ~ ...
  • Software Configuration Management - A practical approach 
    Du Preez, L.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A brief description of software configuration management principles is given, followed by a discussion on the application of these principles in a specific installation.
  • Knowledge-based selection and combination of forecasting methods 
    Finnie, G.R. (South African Institute of Computer Scientists and Information Technologists, 1991)
    Forecasting techniques are used extensively in a variety of business (and other) applications for the analysis and prediction of various factors of interest e.g. future market demand for a specific product. However, the ...
  • An analysis of the usage of systems development methods in South Africa 
    Erlank, S; Pelteret, D; Meskin, M (South African Institute of Computer Scientists and Information Technologists, 1991)
    The systems development process is commonly described in terms of a System Development Life Cycle (SDLC). There is a wide range of tools and techniques available to the system developer, and these are typically used for ...
  • CID3: an extension of ID3 for attributes with ordered domains 
    Cloete, I; Theron, H (South African Institute of Computer Scientists and Information Technologists, 1991)
    Quinlan's ID3 is a popular and efficient algorithm for inducing decision trees from concept examples, where the examples are presented as vectors of attribute-value pairs. If some attributes have integer or real domains ...
  • An interrupt driven paradigm of concurrent programming 
    Clayton, Peter G. (South African Institute of Computer Scientists and Information Technologists, 1991)
    This paper introduces a class of concurrent programming construct based on an interrupt driven paradigm. This programming model is designed to simplify the application of conventional imperative programming techniques ...
  • An ADA compatible specification language 
    Bosua, R; Du Plessis, A.L (South African Institute of Computer Scientists and Information Technologists, 1991)
    Specification languages to be used in conjunction with Ada as the implementation language have been proposed in the literature. Simultaneously, methods for the development of real-time software systems have been introduced, ...
  • Hypertext for browsing in computer aided learning 
    Barrow, J (South African Institute of Computer Scientists and Information Technologists, 1991)
    Hypertext is presented as a database accessing mechanism well-suited to computer aided learning applications. On the basis of informal experiments with prototype software, some benefits of structured hypertext are explored. ...
  • A model checker for transition systems 
    De Villiers, PJA (South African Computer Society (SAICSIT), 1992)
    A model checker automatically determines whether a model of a reactive system satisfies its specification. Temporal logic is used to specify the intended behaviour of a reactive system which is modelled as a transition ...
