  • A complexity metrics model for software 
    Torn, A; Andersson, T; Enholm, K (South African Computer Society (SAICSIT), 1999)
    A complexity metrics model for software is introduced. The model is defined as l( p )c( p ) = e( p ), where p is any piece of software, l( p ) its length, c( p ) an average type complexity measure independent of length, ...
  • Co-operating to learn using JAD techniques 
    Thomas, TA (South African Computer Society (SAICSIT), 1999)
    The role of the Information Systems' (IS) developer is changing. IS developers are required to be able to work with users and get a common understanding with them. In order to achieve this, the developers must have not ...
  • Grounded theory methodology in IS research: Glaser vs Strauss 
    Smit, J (South African Computer Society (SAICSIT), 1999)
    Grounded Theory (GT), along with the surging interest in qualitative research, is becoming a popular research strategy in the Information Systems (IS) field. At the same time however, the method seems to be changing in its ...
  • 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, ...
  • An object-oriented framework for rapid client-side integration of information management systems 
    Schimkat, RD; Kuchlin, W; Krautter, R (South African Computer Society (SAICSIT), 1999)
    Reuse of software components offers the potential for significant savings in application development costs and time. This paper provides a characterization of reuse at different levels of client-based software in distributed ...
  • Visualising eventuality structure 
    Rock, ST (South African Computer Society (SAICSIT), 1999)
    This paper describes the use of pictorial representations in showing the understanding of natural language that is about multiple or extended events. The focus is on the structure of such eventualities, and depiction of ...
  • Active learning: Issues and challenges for information systems and technology 
    Quilling, RD; Erwin, GJ; Petkova, O (South African Computer Society (SAICSIT), 1999)
    Changes following South Africa's first democratic election when Nelson Mandela was elected President, have stimulated reviews of many economic, political and social structures including those in national education. One of ...
  • Distributed operating systems: a study in applicability 
    Prange, J; Bishop, J (South African Computer Society (SAICSIT), 1999)
    This study will attempt to show the path of research and development of a huge and currently implemented SCADA (Super­visory Control and Data Acquisition) system product. The designers and their managers have identified ...
  • An application of a framework for evaluation of the factors affecting software development productivity in the context of a particular organisational environment 
    Petkova, O; Roode, JD (South African Computer Society (SAICSIT), 1999)
    The goal of this paper is to present the practical implementation of a novel framework for evaluation of the factors affect­ing software development productivity, combining elements from several systems approaches and ...
  • The development of a generic framework for the implementation of a cheap, component-based virtual video-conferencing system 
    Panagou, S; Bangay, S (South African Computer Society (SAICSIT), 1999)
    We address the problem of virtual-videoconferencing. The proposed solution is effected in terms of a generic framework based on an in-house Virtual Reality system. The framework is composed of a number of distinct components: ...
  • A pragmatic approach to bitemporal databases: conceptualisation, representation and visualisation 
    Njovu, C; Gray, WA (South African Computer Society (SAICSIT), 1999)
    In this paper, we describe a pragmatic approach to bitemporal data modelling, logical representation and visualisation. Our proposed approach, herein referred to as the Bitemporal Object, State and Event Modelling Approach ...
  • Improving object oriented analysis by explicit change analysis 
    Yu, L; Khong, SC; Xun, Y; Yuan, M (South African Computer Society (SAICSIT), 1999)
    Changeability is one of the major concerns in software development. OO (Object-Oriented) technology itself is not enough to solve this problem, i.e. software systems cannot have enough changeability by just using any ...
  • BuRS: a building recognition system 
    Levitt, SP; Dwolatzky, B (South African Computer Society (SAICSIT), 1999)
    In this paper the design of a novel building extraction system, entitled BuRS, is proposed. It is capable of identifying man-made structures that are visible in monocular greyscale aerial photography of rural settlements ...
  • What are websites used for - cost saving, revenue generating or value creating? 
    Lee, M (South African Computer Society (SAICSIT), 1999)
    For responding to the previous debate about whether Websites can be more properly used as a cost saving or revenue generating devices. The author interprets Plehan's internet selling matrix in a particular way to provide ...
  • An information-theoretic semantics for belief change 
    Meyer, TA (South African Computer Society (SAICSIT), 1999)
    Belief change is an interdisciplinary topic and is researched in departments of Computer Science, Artificial Intelligence, Philosophy, Mathematics and Engineering. It is therefore not surprising that there are a variety ...
  • Formal verification with natural language specifications: guidelines, experiments and lessons so far 
    Holt, A (South African Computer Society (SAICSIT), 1999)
    The industrial take-up of formal verification techniques remains limited. Allowing specifications to be expressed in natural language (perhaps augmented with diagrams) offers the prospect of increasing the usability of ...
  • 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 ...
  • Understanding HCI methodologies 
    Warren, P (South African Computer Society (SAICSIT), 1999)
    The paper proposes a framework for discussing methodologies for developing interactive computer systems. It uses this framework for a sample of systems and shows how certain insights about missing aspects of the methodologies ...
  • Conceptual design of gasification-based biorefineries using the C-H-O ternary diagram 
    Litheko, Lefu Andrew (2017-10)
    This dissertation develops a systematic targeting method based on the C-H-O ternary diagram for the conceptual design of gasification-based biorefineries. The approach is applied using dimethyl ether (DME) as case study. ...
