  • 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 ...
  • 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 ...
  • Information security awareness, a must for every organization 
    Thomson, M; Von Solms, R (2000)
    Information Technology (IT) has become part and parcel of the business world today. In fact, with the increasing sophistication of networks and the continued growth in electronic commerce, it will continue becoming an ever ...
  • 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 ...
  • 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 ...
  • An investigation in software process improvement in the software development of a large electricity utility 
    Lang, MT; Walker, AJ (2000)
    Process improvement techniques as well as metrics have just recently been implemented in the software development department in the Eskom Information Technology Department. The techniques implemented are Function Point ...
  • 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 ...
  • 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 ...
