  • Integrating similarity-based and explanation-based learning 
    Oosthuizen, GD; Avenant, C (South African Institute of Computer Scientists and Information Technologists, 1992)
    Recently, there have been various attempts to combine the strengths of similarity-based learning (SBL) and explanation­-based learning (EBL) in a single learning system. We describe a graph-based learning method called ...
  • Intelligent production scheduling: A survey of current techniques and an application in the footwear industry 
    Ram, V (South African Computer Society (SAICSIT), 1994)
    Computer Based Scheduling is an important activity especially in automated environments such as CIM (Computer Integrated Manufacturing ) where it is an integral part of the total manufacturing function. Developments in ...
  • 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 ...
  • Introducing a continuum of abstraction-led hierarchical search techniques 
    Zimmer, R; Holte, R (South African Computer Society (SAICSIT), 1999)
    Abstraction in search works by replacing a state space by another space (the abstract space) that is easier to search, either because it is smaller or because it contains more solutions. Results of searches in the abstract ...
  • Introducing research methods to Computer Science honours students 
    Galpin, V; Hazelhurst, S; Mueller, C; Sanders, I (South African Computer Society (SAICSIT), 1999)
    Research skills are important for any academic and can be of great benefit to any professional person. These skills are, however, difficult to teach and to learn. In the Department of Computer Science at the University ...
  • Introduction to computability theory 
    Zucker, J; Pretorius, L (South African Computer Society (SAICSIT), 1993)
    These are notes for a short introductory course on Computability Theory (or recursive function theory). The basic notion of computability is defined in terms of a simple imperative programming language.
  • An investigation in the separation of the application from its user interface 
    Greyling, JH; Warren, PR (South African Institute of Computer Scientists and Information Technologists, 1991)
    The separation of an interactive program's application from its user interface is investigated. In order to support good human interaction, the interface requires a deep knowledge of the application. This is in direct ...
  • A Java client/server system for accessing arbitrary CANopen fieldbus devices via the Internet 
    Buhler, D; Nusser, G; Gruhler, G; Kuchlin, W (South African Computer Society (SAICSIT), 1999)
    This paper describes the Java CAN API a portable and extensible application interface to arbitrary CANopen fieldbus devices. This API forms the basis for the implementation of JRCC (Java Remote CAN Control), a tool which ...
  • The key issues in information management in the mid-1990s. Back to business basics through the commercialisation of the ISD 
    Remenyi, DSJ (South African Computer Society (SAICSIT), 1993)
    This paper takes a business or commercial perspective of the key issues in Information Management for the mid-1990s. It focuses on how organisations may use information systems to improve their efficiency and effectiveness ...
  • Knowledge representation using formal grammars 
    Von Solms, S.H.; Ehlers, E.M.; Enslin, DJ (South African Institute of Computer Scientists and Information Technologists, 1991)
    In this paper, formal grammars, specifically random context grammars, are used as a vehicle for knowledge representation in expert systems. Random context grammars and the manner in which they are used to represent knowledge ...
  • 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 ...
  • Kritiese faktore vir die suksesvolle afhandeling van inligtingstelselprojekte 
    Bruwer, P.J.S. (South African Institute of Computer Scientists and Information Technologists, 1990)
    During the past 30 years the rapid evolution and distribution of information systems have brought about a change in the issues surrounding information systems projects. The technical, internal and external environment ...
  • A lattice-theoretic model for relational database security 
    Melton, A; Shenoi, S (South African Computer Society (SAICSIT), 1992)
    It is often the case that a major concern with databases is security. In this paper we introduce a new model for database security. The basic idea of this new model is that answers to queries are based on equivalent data ...
  • Lessons from Singapore and Zimbabwe: A model for emerging countries to achieve quality economic growth 
    Yellen, RE; Sanford, CC (South African Computer Society (SAICSIT), 1995)
    The Singapore government's adoption of policies which has promulgated an infrastructure heavily reliant on information technology is used as a model to explain Singapore's remarkable economic growth. This model helps to ...
  • Limitations and problems of management applications that use enterprise extensions to the SNMP MIB 
    Oosthuysen, WH; McDonald, T (South African Computer Society (SAICSIT), 1995)
    Until some years ago, management of TCP/IP based products was done in a proprietary fashion. Many large companies build their own system-wide management facilities because of a lack of usable systems to manage heterogeneous ...
  • A Linda solution to the evolving philosophers problem 
    Hazelhurst, SE (South African Institute of Computer Scientists and Information Technologists, 1991)
    The dining philosophers problem and the evolving philosophers problems are abstractions of resource sharing problems in parallel and distributed systems. A Linda solution to the dining problem has already been shown; this ...
  • A linear time algorithm for the longest (s-t)-path problem restricted to partial k-trees 
    Mata-Montero, M; Ellis, JA (South African Computer Society (SAICSIT), 1994)
    The Longest (s-t)-path Problem, a known NP-complete set, is shown to admit a linear time solution when the instances of the problem are restricted to partial k-trees. This class of graphs is defined and some of the properties ...
  • A logic for the design of multiprogramming systems 
    Misra, J (South African Computer Society (SAICSIT), 1998)
    This paper presents a short introduction to the UNITY logic, a fragment of linear temporal logic. The logic was designed to specify safety and progress properties of reactive systems. A version of the UNITY ...
  • Logic programming: ideal vs practice 
    Labuschagne, W.A.; Van der Westhuizen, PL (South African Computer Society (SAICSIT), 1992)
    The logician who encounters logic programming expects it to involve 'using predicate logic as a programming language'. He is soon disillusioned. He discovers that it really means 'programming in PROLOG', which in tum seems ...
  • Machine translation from African languages to English 
    Kourie, D.G.; van den Heever, WJ; Oosthuizen, GD (South African Computer Society (SAICSIT), 1992)
