  • Coping with degeneracy in the computation of Dirichlet Tessellations 
    Buys, J; Messerschmidt, HJ; Botha, JF (South African Institute of Computer Scientists and Information Technologists, 1990)
    A modification to the Dirichlet tessellation algorithm of Green and Sibson {1} is presented which deals effectively with degenerate and near-degenerate vertices and allows the construction of a ...
  • Data structuring via functions 
    Venter, BH (South African Institute of Computer Scientists and Information Technologists, 1990)
    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 ...
  • An Estelle compiler for a protocol development environment 
    Kritzinger, PS; van Dijk, J (South African Institute of Computer Scientists and Information Technologists, 1990)
    The development of communication protocol standards has been accompanied by the standardization of formal specification languages to describe these standards in a clear and unambiguous way. Simulta­neously, techniques for ...
  • Homological transfer: an informations systems research method 
    Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Information systems are members of a large class of similar systems called "productive processes". The existence of similarities between manufacturing, financial, educational, informational and other productive processes ...
  • Implementing UNIX on the INMOS transputer 
    McCullagh, PJ; Smit, G de V (South African Institute of Computer Scientists and Information Technologists, 1990)
    The transputer is examined as the target for a UNIX port and specific problems encountered during implementation of a UNIX kernel in a transputer environment are discussed. Some solutions to the problems are suggested and ...
  • On the generation of permutations 
    Naccache de Paz, D (South African Institute of Computer Scientists and Information Technologists, 1990)
    A new incremental algorithm for generating permutations on 1,2,..n (hereafter called "arrangements') is presented. The scheme generates arrangement k +1 by reversing a certain prefix of its predecessor and linking it to ...
  • Opening address: Vth SA Computer Symposium 
    Viljoen, HC (South African Institute of Computer Scientists and Information Technologists, 1990)
    You may know that I am sitting on two chairs at the present moment: one, at the University of Stellenbosch in the Chair of Electronic Engineering as Dean of Engineering; the other at the SABC as chairman of the Board of ...
  • Predicting the performance of shared multiprocessor caches 
    Goosen, HA; Cheriton, DR (South African Institute of Computer Scientists and Information Technologists, 1990)
    We investigate the performance of shared caches in a shared-memory multiprocessor executing parallel programs, and formulate simple models for estimating the load placed on the bus by such a shared cache. We·analyze three ...
  • A review of the use of computers in education in South Africa Part 1: Primary and High schools 
    Fallick, PM; Pistorius, MC (South African Institute of Computer Scientists and Information Technologists, 1990)
    This informal review is based on personal discussions carried out within the last year with various experts in the field as to the current use of computers in primary and secondary schools. An attempt has been made to ...
