  • A model for object-oriented databases 
    Brand, M; Wood, PT (South African Computer Society (SAICSIT), 1992)
    Unlike the relational model, there is no universally accepted object-oriented data model. This has led to systems being defined in an ad-hoc manner, with the resultant difficulty of determining exactly what features are ...
  • A model to evaluate the success of information centres in organizations 
    Bruwer, P.J.S.; Groenewald, J.J. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The objective of this research report was to investigate some South African organizations who have been operating information centres (IC's) successfully for more than two years. As the success of the IC is strongly · ...
  • Model-based segmentation of CT images 
    Marte, O-C; Marais, P (2001)
    This paper presents preliminary work on the segmentation of Computed Tomography data using a model-based approach. Conventional image processing of CT data is aimed at the production of simple iso-surfaces far surgical ...
  • Modeller : a DSS for experimental study of Human-computer interaction 
    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    This paper describes the structure of a simple nonprocedural financial modelling system designed to collect a variety of statistics on aspects of novice interaction with decision support systems. Some findings on the use ...
  • Modelling Blocking on Admission of Tasks to Computer Systems 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    The need for modelling techniques to allow blocking of tasks prior to admission to the computer system in queueing network models is described. A detailed algorithm which presents a technique to enforce blocking by priority ...
  • Modelling distributed database concurrency control overheads 
    Rennhackkamp, MH (1987)
    Numerous concurrency control methods have been proposed for distributed databases. Various criteria are used to compare these methods. The comparisons range from qualitative overviews through quantitative analyses ...
  • Modelling distributed database concurrency control overheads 
    Rennhackkamp, M.H.; Von Solms, S.H. (Computer Society of South Africa (on behalf of SAICSIT), 1988)
    Numerous concurrency control methods have been proposed for distributed databases. Various crz·teria are used to compare these methods. The comparisons range from qualitative overviews through quantitative analyses to ...
  • Modelling the algebra of weakest preconditions 
    Brink, C; Rewitzky, I (1991)
    Dijkstra's weakest precondition semantics, as presented in textbook form by Gries, may be viewed as an equational algebra. The problem then is to find a reasonable (set-theoric) model of this algebra. This paper provides one.

  • Models to evaluate the state of computer Facilities at South African universities 
    Bruwer, P.J.S.; Hattingh, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    Computer technology has grown exponentially in the course of the past decade in terms of sophistication - not only with regard to hardware and networks, but also with regard to mainframe and micro-computer systems. ...
  • Modular neural networks subroutines for knowledge extraction 
    Vahed, A; Cloete, I (1996)
    Current research in modular neural networks (MNNs) have essentially two aims; to model systematic methods for constructing neural networks of high complexity and secondly, to provide building blocks for hybrid symbolic- ...
  • More readings than I thought: quantifier interaction in analysing the temporal structure of repeated eventualities 
    Rock, S (2000)
    Focusing on the temporal structures of the events described by language, the sentence 'Simmer the soup stirring it occasional(y for fifteen minutes' without punctuation, has three syntactic structures, which give rise to ...
  • A multi-criteria partitioning technique for information system design 
    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, ...
  • Multilingual training of acoustic models in automatic speech recognition 
    Nieuwoudt, C; Botha, EC (South African Computer Society (SAICSIT), 2000)
    This paper evaluates the performance of a speech recognition system using acoustic models trained on multilingual data. The reason in our case for using data from more than one language is that there may not be enough ...
  • Multimedia as a positive force to leverage web marketing, with particular reference to the commercial sector 
    Shear, S (South African Computer Society (SAICSIT), 1999)
    The Internet (World-Wide-Web) has opened a whole new dimension into advertising, and there is little doubt that audio and video- the basic components of conventional advertising, will play a role there as well. However, ...
  • The multiserver station with dynamic concurrency constraints 
    Kriel, CF; Krzesinski, AE (South African Computer Society (SAICSIT), 1992)
    This paper defines the the Multiserver Station With Dynamic Concurrency Constraints. The MSDCC station consists of B parallel identical exponential servers. The customers requesting service at the MSDCC station belong to ...
  • A multitasking operating system above MS-DOS 
    Foss, RJ; Rehmet, GM; Watkins, RC (South African Computer Society (SAICSIT), 1992)
    This paper describes the development of a memory resident version of the Xinu operating system for the IBM PC range of computers. The operating system co-resides with the MS-DOS operating system. The need for the operating ...
  • Nebulas as Structural Data Models 
    Van Rooyen, H.O.; Weiermans, D.J. (Computer Society of South Africa (on behalf of SAICSIT), 1983)
    Nebula modell_ing is_ a generalised structural modelling technique which applies to any finite set of objects (entities) and n-ary relat1onsh1ps (n ~2). A nebula model can be presented in either diagrammatic or tabular ...
  • A network model for the prioritization of factors affecting software development productivity 
    Petkov, DI; Mihova-Petkova, O (1995)
    The aim of this research is to provide a new model for the prioritization of the various quantitative and qualitative factors affecting software development productivity. This is important for the evaluation of project ...
  • Network partitions in distributed databases 
    Viktor, HL; Rennhackkamp, MH (South African Computer Society (SAICSIT), 1992)
    The technology of distributed databases is based on two other technologies which have developed a solid foundation: computer networks and centralized databases. A distributed database designer should therefore address ...
