  • 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 ...
  • Li, F; Liu, Y; Lee, JY; Ahmad, I (South African Computer Society (SAICSIT), 1999)
    In this paper, we propose scheduling algorithms for call admission control servers. For each requested video, the server sends it according to its smoothed profile aims at maximizing resource utilization and ease of network ...
  • Galpin, V; Hazelhurst, S; Mueller, C; Sanders, I (South African Computer Society (SAICSIT), 1999)
    Research skills are important for any academic and can be of great benefit to any professional person. These skills are, however, difficult to teach and to learn. In the Department of Computer Science at the University ...
  • 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 ...
  • 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 ...
  • Lawrence, E; Garner, B (South African Computer Society (SAICSIT), 1999)
    The advent of Internet Commerce represents a significant threat to taxation revenue collection for governments throughout the world. Governments cannot prevent the creative and innovative commercial use of the Internet in ...
  • 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 ...
  • Handzic, M; Low, G (South African Computer Society (SAICSIT), 1999)
    This paper reports the results of an empirical examination of the effects of experience in using a multifunctional information technology on users' perceptions of its usefulness and ease of use in a university task context ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Van den Bergh, F; Lalioti, V (South African Computer Society (SAICSIT), 1999)
    This paper presents a very fast software chroma keying algorithm, requiring at most five integer operations per pixel. An improvement of more than 300% in performance over HLS based algorithms was achieved. The algorithm ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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, ...
  • 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 ...
