  • 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 ...
  • The skills hierarchy and curriculum 
    Machanick, P (1998)
    A commonly accepted hierarchy of cognitive skills puts analysis and synthesis near the top, with straightforward knowledge and comprehension at the bottom. A typical Computer Science curriculum, though, usually starts ...
  • 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. ...
  • Management aspects of client/server computing 
    Langa, S (1998)
    The purpose of the research is to investigate the management aspects of client/server computing. The latter is seen as a prerequisite for better management of all aspects of client/server computing. Noting the fact that ...
  • Hardware system interfacing with Delphi 3 to achieve academic integration between the fields of computer systems and software engineering 
    Joubert, A; Jordaan, A (1998)
    This paper explores the use of dive computer downloader units and Delphi 3 object-oriented structures to integrate the fields of Computer Systems and Software Engineering in the academic environment. Currently there is a ...
  • 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 ...
  • Implications of emerging DRAM technologies for the RAMpage memory hierarchy 
    Machanick, P; Salverda, P (1998)
    The RAMpage memory hierarchy is an attempt at devising a comprehensive strategy to address the growing DRAM-CPU speed gap. By moving the main memory up a level to the SRAM currently used to implement the lowest-level ...
  • An integrated research programme in AI applied to telecommunications at M L SULTAN Technikon 
    Nepal, T; Andrew, T (1998)
    With the introduction of the degree programs in technikons the call for research outputs sounds increasingly urgent. Technikons have now realised that they are well positioned to also undertake applied and experimental ...
  • Managing large programming classes using computer mediated communication and cognitive modelling techniques 
    Harmse, RG; Pullen, G (1998)
    This paper describes a proposed solution to address some of the problems encountered when attempting to teach programming to a large number of students with diverse backgrounds and vastly different levels of technological ...
  • Quality academic development of CS/IS infrastructure in South Africa 
    Masethe, HD; Dandadzi, TA (1998)
    A change in the Strategic Infrastructure Development (SID) approach is called for in order to build academic quality. In the past the Information System (IS) infrastructure in South Africa was designed towards literacy ...
  • Effective information security monitoring using data logs 
    Krige, W; Von Solms, R (1998)
    Log files or audit logs are files that record information about events that occur on a computer system at all times, that is if the log files are configured correctly. Most information security officers do not use this ...
  • A conceptual model for the adoption and use of CASE technology 
    Huisman, HM (1998)
    The software crisis has been well documented. Software is being delivered late, over budget and full of residual faults. In an attempt to solve these problems, CASE technology has been developed. CASE technology provides ...
  • 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 ...
  • Quality learning, learning quality 
    Van Zyl, J (1998)
    The purpose of this paper is to describe the Leaming Model and related concepts. In the context of this paper, the following principles are discussed: • What do we need to learn? • How must we learn it? These two ...
  • INSTAP: Experiences in building a multimedia application 
    Venter, L (1998)
    INSTAP is a multimedia program to teach Afrikaans at first year university level. The intended audience consists of students who come from non-Afrikaans speaking communities, and hence sound is a very important aspect of ...
