  • Characteristics of high-performing information systems project managers and project teams 
    Smith, DC (1998)
    Projects, and their success, are vital if organisations are to produce new products and services. The key players in IS projects are the project manager and the project team. This paper discussed ongoing research of two ...
  • Non-orthogonal ray guarding 
    Sanders, I (1998)
    In an earlier paper the notion of a ray guard --'- a guard that can only see along a single ray, was introduced. The ray guarding problem is in siting the fewest possible such guards so that they guard all adjacencies ...
  • Design patterns for user interfaces 
    Warren, PR Viljoen, M (1998)
    This work reports on 23 third year student' s projects in which the user interfaces (UI) were found wanting. We show in which ways we regard the UI to be in error. However, an examination of the available literature on UI ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • One way to make better decisions related to IT outsourcing 
    Petkov, D Petkova, O (1998)
    The subject of IT outsourcing has received a growing attention recently both by practitioners and researchers. There are a number of critical decisions to be made by a company embarking on outsourcing. These include a ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
