  • 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 ...
  • 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 ...
  • The effects of virtual banking on the South African banking industry 
    Dunley-Owen, M Hart, ML (2000)
    The South African banking industry is set to undergo a complete transformation in the next ten years. One of the main reasons for this transformation is the development of virtual banking, specifically new delivery channels ...
  • 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 ...
  • 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 ...
  • Combining rule-based Artificial Intelligence with Geographic Information Systems to plan the physical layer of wireless networks in Greenfield areas 
    Prag, K Premjeeth, P Sandrasegaran, K (2000)
    This paper elucidates the development of a computer tool which combines the use of terrain data in a Geographic Information System (GIS), an equipment database and rule-based inference. It explores the use of GJS to aid ...
  • 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 ...
  • Cardinality constrained 0-1 Knapsack problems 
    Kruger, MF Hattingh, JM Steyn, T (2000)
    The Knapsack Problem is one of the most important problems in Discrete optimization. Although it is the simplest integer program, it has numerous practical applications and often appears as a subproblem in solving more ...
  • Algebraic factorization of integers using BDE's 
    Messerschmidt, HJ Robertson, J (2000)
    This paper outlines a new direct algebraic method for the factorization of integers. It shows how by using a mixed binary - decimal multiplication scheme the multiplication can be reconstructed from the product only. This ...
  • 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 ...
  • Access control needs in an electronic workflow environment 
    Botha, RA (2000)
    This paper defines an electronic workflow environment as being conducive to the performance of business processes according to certain policies and practices in an electronic fashion. The workflow procedure will be facilitated ...
  • 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 ...
  • Developing soft skills in computer students 
    Schroder, C Thomas, T (2000)
    Today software developers are required to work closely with users when defining, developing and implementing systems. Interaction between software developers and users can influence the success or failure of the system ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
