  • Approaches to video transmission over GSM networks 
    Du, B; Maeder, A (South African Computer Society (SAICSIT), 1999)
    Real-time video delivery adds an aspect of reality when used in conjunction with other computer and human communi­cations facilities (eg in videophone or videoconferencing applications). However, the complex and time-critical ...
  • 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 ...
  • The CILT multi-agent learning system 
    Viktor, HL (South African Computer Society (SAICSIT), 1999)
    A multi-agent learning system consists of two or more learners or learning agents that co-exist in a learning environment. The learners have the ability to learn together, thus utilizing one another's strengths and ...
  • 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 ...
  • 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, ...
  • Computer programming and learning to write 
    Barrow, J (South African Computer Society (SAICSIT), 1999)
    Programming is often seen in terms of mathematical models. An additional perspective, that of programming as a means of communication between the programmer and the computer, can also be useful, particularly in teaching ...
  • A conceptual design for high-volume data processing of warehouse database into multidimensional database 
    Trakulsuk, P; Avatchanakorn, V (South African Computer Society (SAICSIT), 1999)
    This paper presents a conceptual model of analyzing huge amount of information from a data warehouse into Multidimensional Database (MDDB) using multidimensional data (MDD)model. The major advantages of this model are: 1) ...
  • Critical success factors for the implementation of DSS at a selection of organisations in Kwazulu/Natal, South Africa 
    Averweg, URF; Erwin, GJ (South African Computer Society (SAICSIT), 1999)
    Decision Support Systems (DSS) are specially developed for supporting the solution of a non-structured management problem for improved decision-making. DSS utilise data, provide easy user interfaces and allow for the ...
  • 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: ...
  • 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 ...
  • Enhancing the predictability of two popular software reliability growth models 
    Keiller, PA; Mazzuchi, TA (South African Computer Society (SAICSIT), 1999)
    In this paper, enhancement of the performance of both the Musa-Okumoto and the Goel-Okumoto Software Reliability Growth models are investigated using various smoothing techniques. The method of parameter estimation for the ...
  • 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 ...
  • From information security baselines to information security profiles 
    Von Solms, R; Van de Haar, H (South African Computer Society (SAICSIT), 1999)
    To protect the information systems of an organization an appropriate set of security controls needs to be installed and managed properly. Many organizations that can afford it conduct either a risk analysis exercise ...
  • Generalised unification of finite temporal logic formulas 
    Hazelhurst, S (South African Computer Society (SAICSIT), 1999)
    Given two temporal logic formulas, g and h, we wish to know whether there is a modification, m, we can make to h so that g ==> m( h). This problem has important applications in hardware verification, where finding such ...
  • A generic modelling framework for interactive authoring support environments 
    Kotze, P (South African Computer Society (SAICSIT), 1999)
    Existing modelling frameworks for the design of interactive systems emphasise the relationship between the system's in­ternal state and the rendering of this state at the user interface. Modern programming and multimedia ...
  • 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 ...
  • Harmonizing global internet tax: a collaborative extranet model 
    Lawrence, E; Garner, B (South African Computer Society (SAICSIT), 1999)
