  • Using multimedia technology for social up-liftment in deprived communities of Southern Africa 
    Bester, L; Du Preez, E (2000)
    In recent years individualized instruction and the use of computer technology to facilitate learning at all levels of education and training has received increased emphasis. The use of computers in education has been ...
  • A model for evaluating information security 
    Barnard, L; Von Solms, R (2000)
    During the last few decades computing environments have advanced from single user systems to distributed, open environments we all know today. Through these Information Technology advancements, more and more role players ...
  • Liming-like curve constructions 
    Baart, L; McLeod, R (2000)
    R.A. Liming developed a method based on classical conic section theory to design cross-sections of aircraft using implicit rather than explicit forms of the quadratic equations. In its basic form the method is used to ...
  • Design and implementation of a C++ package for two-dimensional numerical integration 
    Laurie, D; Pluym, L; Cools, R (2000)
    Numerical integration in two dimensions is dominated by the geometry of the region. Good integration formulas are known only for a few simple regions, making it necessary in general to subdivide regions into simpler ...
  • A distributed approach to the scheduling problem 
    Ram, V; Warren, P (2000)
    The focus of many Artificial Intelligence approaches to solving the computer-based scheduling problem is on reducing the size of the search spaces that characterise such problems. The approach presented in this paper ...
  • Information systems development and multicriteria decision making / systems thinking 
    Petkova, O; Petkov, D (2000)
    Multicriteria Decision Making and Systems Thinking both claim to be useful when dealing with complex, messy managerial problems. They have evolved in a different way in the past 20 years and only recently there have been ...
  • Global optimisation of routes after the process of recovery 
    Mphahlele, M; Roos, J (2000)
    Survivability in connection-oriented ATM networks is critical due to link and node failures. With regard to high priority connections, it is important that the network maintains their performance guarantees. The restoration ...
  • On indexing in case based reasoning applied to pre-transportation decision making for hazardous waste handling 
    Wortmann, KL; Petkov, D; Senior, E (2000)
    Case Based Reasoning is an Artificial Intelligence technique that utilises the concept of reasoning from a stored knowledge base reflecting prior experience. It offers a number of advantages, such as learning and validation ...
  • Integrating spatial data management and object store technology 
    Berman, S; Buffler, S; Owen, J; Voges, E (2000)
    Efficient access to spatial data is essential for many engineering, town planning and mining applications. Conventional database systems are not capable of performing such searches effectively over large data sets. Relational ...
  • 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 ...
