  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • A pluralist systemic framework for the evaluation of factors affecting software development productivity 
    Petkova, O; Roode, JD (1998)
    pAst software development productivity research has taken two main directions: in the first, research has concentrated on determining the factors which have a significant effect on productivity; and in the second, the ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Quality considerations of real time access to multidimensional matrices 
    Janssen, F (1998)
    This paper investigates the quality considerations of real time access to multidimensional matrices. Researchers have emphasised the relationship between multidimensional matrices and data warehousing in the past; the ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Response surface analysis as a technique for the visualization of linear models and data 
    Terblanche, F; Hattingh, G (1998)
    Response surface analysis aims of exploring the behavior of a response function in some region. Some authors (see e.g. [BRU] and [DEV]), have used this approach to get "better" interpretations of the behavior of linear ...
  • 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 ...
  • 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 ...
  • 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. ...
