  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Wood, PT (South African Institute of Computer Scientists and Information Technologists, 1990)
    Increasing the expressive power of relational query languages by providing some form of recursion is currently a topic of much research. For many recursive queries in relational databases, a relation can be represented ...
  • Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1990)
    A distributed database management system must facilitate integrated processing of data which is physically distributed over a network of node computers, while providing locality transparency. The NRDNIX prototype has ...
  • Oosthuizen, GD (South African Institute of Computer Scientists and Information Technologists, 1990)
    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, ...
  • Murrell, HC; Carson, D (South African Institute of Computer Scientists and Information Technologists, 1990)
    The continuous and discrete Hartley transforms are real valued transforms that have similar properties to the continuous and discrete Fourier transforms. In addition, a fast algorithm exists for computing the discrete ...
  • Mueller, C.S.M. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Induction has been used as a major tool in mathematics in proving theorems. This paper explores whether it has an equally important role in formulating programs. There are those who advocate that induction should be used ...
  • Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    In order to design and operate a complex computer based information system, one needs to partition its transformation process into modules of manageable size. The same process can be partitioned in many different ways, ...
  • Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Both in the advancement of Information Systems theory and in practical development projects, significant errors of omission can occur unless one is aware of all aspects of the concept "information system success". At least ...
  • Kambanis, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    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 ...
