  • The practical application of a new class of 2D non-linear smoothers for digital image processing. 
    Cloete, E (1996)
    Modern applications in computer graphics and telecommunications command high performance filtering and smoothing corrections to be implemented in real-time. The recent development of a new class of non-linear smoothers for ...
  • The relational organisation model 
    Laauwen, B (1996)
    It has become clear that today's complex society of specialised individuals has a need for problem solving techniques using an integrated and interdisciplinary approach. The popularity of business re-engineering beliefs ...
  • On total systems intervention as a systemic framework for the organisation of the model base of a decision support systems generator 
    Petkov, D; Mihova-Petkova, O (1996)
    Decision Support Systems(DSS) have been dealing so far predominantly with semistructured problems for which existed well established Operations Research techniques. Most of them were originally oriented towards supporting ...
  • The feasibility problem in the simplex algorithm 
    Scott, TG; Hattingh, JM; Steyn, T (1996)
    The simplex method is one way of solving a linear programming problem (LP-problem). The simplex method needs a basic feasible solution to start the solution process. This requires an available non-singular basis. Normally ...
  • A methodology for integrating legacy systems with the client/server environment 
    Redelinghuys, M; Steenkamp, AL (1996)
    The research is conducted in the area of software methodologies with the emphasis on the integration of legacy systems with client/server environments. The investigation starts with identifying the characteristics of legacy ...
  • Modular neural networks subroutines for knowledge extraction 
    Vahed, A; Cloete, I (1996)
    Current research in modular neural networks (MNNs) have essentially two aims; to model systematic methods for constructing neural networks of high complexity and secondly, to provide building blocks for hybrid symbolic- ...
  • Information systems outsourcing and organisational structure 
    Hart, ML; Vavatzanidis, K (1996)
    A decision of increasing importance to many organisations is whether to use internal or outside resources, assistance and expertise to address information technology and information systems requirements. This decision may ...
  • 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 ...
  • 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 ...
  • 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 ...
