1989 5th South African Computer Symposium: Recent submissions

  • Implementing UNIX on the INMOS transputer 
    McCullagh, P. Smit, G. de V. (SAICS, 1989-11-29)
    This paper examines the transputer as the target for a UNIX port and discusses specific problems that were encountered during implementation of a UNIX kernel in a transputer environment. Some solutions to the problems are ...
  • The use of a lattice for fast pattern matching 
    Oosthuizen, G.D. (SAICS, 1989-11-29)
    Pattern recognition involves the matching of a given pattern against a collection of patterns in store in order to identify the given pattern as belonging to a particular class already known to the system or not. Similarly, ...
  • Induction of decision trees in a domain with continuous attributes 
    Cloete, I. Theron, H. (SAICS, 1989-11-29)
    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. For attributes with large, continuous domains ID3 ...
  • A design environment for semantic data models 
    Kambanis, J. (SAICS, 1989-11-29)
    This paper describes the functionality and architecture of a Semantic Data Modeling environment. It integrates User Interface techniques used in Computer Aided Software Engineering and Expert Systems shells into a system ...
  • An interrupt driven paradigm of concurrent programming 
    Clayton, P.G. (SAICS, 1989-11-29)
    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 to ...
  • The case for functional programming 
    Wentworth, E.P. (SAICS, 1989-11-29)
    Functional programming has gained a foothold in academic institutions, and the first commercial interests have been noted. The paradigm is presented by way of some small examples, and arguments are given in favour of this ...
  • A pipelined control strategy for inferencing 
    Kourie, D.G. Potgieter, A.E.G. (SAICS, 1989-11-29)
    The task of deriving a solution to a goal from a Hom clause database is seen in terms of finding a solution tree as a subtree of an and/or tree. The way in which various well-known control strategies derive such solutions ...
  • Data structuring via functions 
    Venter, B.H. (SAICS, 1989-11-29)
    A programming language data model is introduced, based on the notions that variables are functions and types are sets of values. It is shown that, despite the simplicity of the underlying mathematical formalism, the data ...
  • Experience with the development of a neural network simulator 
    Cloete, I. Ludik, J. (SAICS, 1989-11-29)
    Researchers experimenting with structured neural networks must be able to imple­ment and test their ideas. Since most of the network models presume much structure, and network architecture design is a major component in ...
  • Ecological applications using a novel expert system shell 
    Riordan, D. Bradshaw, J.A. Carden, K.J. (SAICS, 1989-11-29)
    Much of the information used by ecologists in modeling and decision making is imprecise. The imprecision arises both from data which is inexact or incom­plete and from the use of ecological principles which are sometimes ...
  • Object-oriented systems, so what? 
    Barth, Gerhard (SAICS, 1989-11-29)
  • Proceedings of the 5th Southern African Computer Symposium, 1989 (Frontmatter) 
    Kritzinger, Pieter (Editor) (SAICS, 1989-11-29)
