  • Error analysis in selected medical devices and information systems 
    Randiki, E (1998)
    The purpose of this paper is to identify and analyse error in selected medical devices: the Datex cardiocap and the capnomac Ultima II. These are both anaesthetic machines used to monitor patients in theatre. A secondary ...
  • Quality aspects of the development of a rule-based architecture 
    Chalmers, C (1998)
    This paper provides an insight into how the various quality requirements defined for a specific tool are met in its development cycle. Focus is on a specific subset of the rule-based architecture project, which covers the ...
  • A case for reuse technology as a CS/IS training infrastructure 
    Adigun, MO (1998)
    The advent of faster computing hardware and sophisticated software tools has not brought with it the much expected panacea for the so-called software crisis, rather we are now facing a software dilemma. Otherwise we should ...
  • Binary decision diagram representations of firewall and router access lists 
    Hazelhurst, S; Fatti, A; Henwood, A (1998)
    The growth of network and internet communication creates several challenges for network design. Two important issues are security and performance. As the volume of communication increases together with the importance of ...
  • Disk delay lines 
    Machanick, P (1998)
    Latency goals often relate to response times seen by users, which are slow by computer standards, but scaling up to large numbers of users presents a problem. Examples include transaction-based systems and web sites. ...
  • On problem structuring in an electronic brainstorming (EBS) environment 
    Kunene, KN; Petkov, D (1998)
    Research in the field of Group Decision Support Systems (GDSS) has focused on the following main issues: the Task (task complexity, clarity and rationality); the Individual (the profile of individual group members); the ...
  • Introducing information security: a comprehensive approach 
    Munyiri, E; Von Solms, R (1998)
    Information has become a very important asset in most organizations today. For this reason, it is imperative that information and the associated resources are properly protected. Traditionally, information assets were ...
  • A partitioning scheme for solving the exact K-item 0-1 knapsack problem 
    Kruger, MF; Hattingh, JM (1998)
    Our investigation on the impact of partitioning the search space of the classical 0- 1 Knapsack Problem through the inclusion of equality constraints on the knapsack's cardinality, has given rise to the study we undertook ...
  • Design of a scalable video on demand architecture 
    Machanick, P (1998)
    The SAVoD (Scalable Architecture for Video on Demand) approach to video on demand exploits the fact that end-user latency goals are relatively modest, while increasing bandwidth is much easier than improving bandwidth. ...
  • A static programming paradigm 
    Mueller, C (1998)
    Formal methods have not as yet succeeded in becoming an accepted way to develop software. This paper explores whether a possible reason for this is the complexity of the tools we use, in particular, the programming paradigms. ...
  • How to gain quality when developing a repository driven user interface 
    Muller, MC (1998)
    When I use the term Repository Driven User Interface (RDUI), it simply means that besides the normal data that users save and use in the running of a business, other data, concerning the user interface is also stored in ...
  • A shell-based approach to information security 
    Papenfus, C; Botha, RA (1998)
    Modem computer systems are truly awe-inspiring fetes of detailed design. Millions of transistors perform billions of instructions every second, linking thousands of people from every continent with a remarkable degree ...
  • Practical experience in running a virtual class to facilitate on-campus undergraduate teaching 
    Brown, S (1998)
    This paper discusses the current use of an Internet Education Support Program (IESP). This software package uses Internet-based tools which allows the educator to use collaborative learning techniques in both face-to-face ...
  • exA security interpretation of the workflow reference model 
    Botha, RA; Eloff, JHP (1998)
    This paper is intended as an opinion paper regarding information security concerns in the Workflow Reference Model (WfRM) as defined by the Workflow Management Coalition (WfMC). After an introduction into the workflow ...
  • Activities of IFIP WG 11.2 (Computer Security Education) & IT related ethics education in Southern Africa 
    Drevin, L (1998)
    l. Activities and purpose of WG 11.8 WG 11.8 is one of the workgroups of TCl 1. WG 11.8 came together on 2 September 1998 on a boat between Vienna and Budapest as part of the IFIP World Computer Congress (WCC '98) where ...
  • Academic CS/IS infrastructure in South Africa; an exploratory stakeholder perspective 
    Bytheway, A; Hearne, G (1998)
    In considering the requirements of an academic infrastructure that might support computer science and information systems education in South Africa, it is easy to be driven solely by the opportunities that innovative ...
  • Reducing fractal encoding complexities 
    Cloete, E; Venter, LM (1998)
    In this paper we address the time complexity problem associated with fractal image coding. In particular, we describe a new hybrid technique called Fractal Vector Quantization coding (FVQ), which takes advantage of the ...
  • Partial edge visibility in linear time 
    Bilbrough, J; Sanders, I (1998)
    This research addresses the problem of partial edge visibility. This problem stems from work done in the ray guarding of configurations of adjacent rectangles [7]. In ray guarding these configurations it is necessary to ...
  • Refuting conjectures in first-order theories 
    De Waal, DA; Hattingh, GN (1998)
    Given some first-order theory, a formula (also called a conjecture) may or may not be a theorem of some theory. A theorem prover attempting to prove that the given formula is a theorem may terminate, proving that the formula ...
  • Critical success factors for implementation of decision support systems 
    Averweg, UR; Erwin, GJ (1998)
    Decision Support Systems (DSS) are used to support decision-making for a non-structured management problem. DSS utilises data, provides an effective user interface and allows for the decision maker's insights to be ...
