  • 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 ...
  • 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 ...
  • 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 ...
  • Model checking software with symbolic trajectory evaluation 
    Hazelhurst, S (1997)
    Traditional methods of testing computer systems, although valuable, are inadequate for ensuring sufficiently high quality in systems in which a high degree of reliability must be placed. Formal methods for development of ...
  • 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 ...
  • More readings than I thought: quantifier interaction in analysing the temporal structure of repeated eventualities 
    Rock, S (2000)
    Focusing on the temporal structures of the events described by language, the sentence 'Simmer the soup stirring it occasional(y for fifteen minutes' without punctuation, has three syntactic structures, which give rise to ...
  • 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 ...
  • Object-oriented business modelling and re-engineering 
    Watzenboeck, M (2000)
    Financial industry and manufacturing are the main customers in migrating existing applications into client server environments. This paper helps in identifying the candidates for migration and suggests a method for ...
  • 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 ...
  • PLaVa: a lightweight persistent Java virtual machine 
    Tjasink, S; Berman, S (2000)
    This paper describes the implementation and tuning of an orthogonally persistent Java Virtual Machine (JVM) for small computers. It is based on a JVM that was targeted at a digital satellite television decoder with 1 ...
  • 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 ...
  • 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 ...
  • Returns on the Stock Exchange 
    Kruger, JW (2000)
    The McGreggor database supplies the accounting information of companies listed on the Johannesburg stock exchange. These attributes are not significantly correlated to the Return. The Pearl's algorithm in Bayesian belief ...
  • A risk model to allocate resources to different computerised systems 
    Kruger, HA; Hattingh, JM (1997)
    The majority of large organisations operate and maintain significant portfolios of computerised systems. All Information Systems (IS) managers are increasingly faced with the task of doing more with less. To cope with ...
  • Software objects change: problems and solution 
    Ajila, SA (2000)
    The development of Software is a long term investment. This investment normally takes a lot of money and human efforts. So many things may change during the life span of a Software. The requirement and the specification ...
  • Theoretical Computer Science: What is it all about, and is it of any relevance to us? 
    Brink, C (2000)
    This is a quite general survey talk in which I present some of the infrastructure, activities and scientific flavour of what has, for better or worse, come to be called "Theoretical Computer Science". I will try to relate ...
  • 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 ...
  • 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 ...
