  • The generation of pre-interpretations for detecting unsolvable planning problems 
    De Waal, DA; Denecker, M; Bruynooghe, M; Thielscher, M (2000)
    In deductive planning, there exists a· particular class of planning problems, called unsolvable planning problems, which although successfully treated theoretically, turns out to be undetectable using ordinary resolution ...
  • The emerging role of the CIO in South Africa 
    Dekenah, B (2000)
    The role of the Chief Information Officer (CIO) and all that it represents has inspired much discussion and speculation, as well as varied and heated debate, in overseas publications. In South Africa however, the title ...
  • Metamodelling in automated software engineering 
    Figueira, R; Berman, S (2000)
    This paper describes a metamodelling system that has been created at the University of Cape Town as part of an integrated software engineering environment called the Persistent Programmers Workshop. The workshop architecture ...
  • A neural network model of a fluidised bed 
    Hajek, M (2000)
    A neural network was used to model experimental fluidisation data - bubble size and velocity - from a laboratory size fluidised bed column. Experiments were performed for several particle sizes and temperatures. A classical ...
  • Representing quadrics on a computer 
    Coetzee, MA; Baart, ML (2000)
    In our research on transfinite interpolation with quadric patches, we needed to draw the part of some quadratic surface that lies between two given planes. In this talk, we discuss a way to parameterize a quadric patch ...
  • A Java-implemented remote respiratory disease diagnosis system on a high bandwidth network 
    Foster, A (2000)
    This telemedicine project is a proof of concept for a remote respiratory disease diagnosis computer system, operating over a high bandwidth network, implemented in Java TM. It hopes to increase medical health in South ...
  • Ray guarding configurations of adjacent rectangles 
    Sanders, I; Lubinsky, D; Sears, M (2000)
    Guarding and covering problems have great importance in Computational Geometry. In this paper the notion of a ray guard, a guard that can only 'see' along a single ray, is introduced. The problem of siting the fewest ...
  • The use of the Internet in an academic environment to commercially supply and support software products. 
    Braude, B; Walker, AJ (2000)
    This paper explores the use of the Internet to supply and support software products within a quality management system. The Software Engineering Applications Laboratory (SEAL) at the University of the Witwatersrand is in ...
  • Using a lattice to enhance adaptation guided retrieval in Example Based Machine Translation 
    Serutla, SL; Oosthuizen, GD (2000)
    Ease of retrieval is of crucial importance in case based reasoning (CBR). In fact, the performance of a CBR system depends on how such a system is able to retrieve relevant cases from memory and adapts them to suit new ...
  • Beliefs of a resource-bounded agent 
    Viljoen, E (2000)
    Logics of belief and knowledge are typically formulated in terms of modal languages. A possible world semantics is traditionally used for such languages but when a formula A is read as "The agent believes that A", the ...
  • Linear response surface analysis and some applications 
    Hattingh, JM (2000)
    In general response surface analysis refers to the modeling of experimental or observational data. Computer technology and graphical techniques obviously play a significant role in the representations of these models. A ...
  • A proposal for dynamic access lists for TCP/IP packet filtering 
    Hazelhurst, S (2001)
    The use of IP filtering to improve system security is well established, and although limited in what it can achieve has proved to be efficient and effective. In the design of a security policy there is always a trade-off ...
  • Towards teaching computer ethics 
    De Ridder, C; Pretorius, L; Barnard, A (2001)
    With the advent of the lnformation Age and global connectivity, the ethical use of Information and Communication Technologies (/CI) has become essential. As the drive towards the establishment of a so-called IT profession ...
  • Effectively exploiting server log information for large scale web sites 
    Wong, B; Marsden, G (2001)
    With the continuing growth of the Internet, an increasing number of organisations are incorporating the Web into their business activities. The appeal of a site to users in terms of both attractiveness and usability ...
  • A pattern architecture: using patterns to define an overall systems architecture 
    Van Zyl, J; Walker, AJ (2001)
    The notion of patterns has been used in many different disciplines, and the software industry is no exception. There are many books written, academic research done and practical examples available of where patterns have ...
  • The effects of avatars on co-presence in a collaborative virtual environment 
    Casanueva, J; Blake, E (2001)
    Presence in Collaborative Virtual Environments (CVEs) can be divided into personal presence and co-presence. Personal presence is having a feeling of "being there" in the CVE oneself. Co-presence is having a feeling that ...
  • Real-time facial animation for virtual characters 
    Burford, DJ; Blake, EH (2001)
    Facial expressions form an important part of human to human communication. In order to exploit the fall potential of computer networks and the Internet for communication and interaction, provision should be made for conveying ...
  • Optimal multi-splitting of numeric ranges for decision tree induction 
    Lutu, PEN (2001)
    Data mining is the process of extracting informative patterns from data stored in a database or data warehouse. Decision tree induction algorithms, from the area of machine learning are well suited for building classification ...
  • Introductory IT at a tertiary level - is ICDL the answer? 
    Dixie, CH; Wesson, JL (2001)
    Research is underway at the University of Port Elizabeth (UPE) to establish a framework for introductory IT courses to match the needs of future graduates of diverse programmes from the Faculties of Arts, Building Sciences, ...
  • JavaCloak - considering the limitations of proxies for facilitating Java runtime specialisation 
    Renaud, K (2001)
    This paper discusses issues pertaining to mechanisms which can be used to change the behaviour of Java classes at runtime. The proxy mechanism will be compared to and contrasted with other standard approaches to this ...
