  • Business process reengineering: management's new paradigm or emperor's new clothes? 
    Jones, MR (South African Computer Society (SAICSIT), 1995)
    Business Process Reengineering (BPR) is currently attracting much attention as an approach to organisational change, but has received relatively little critical scrutiny. This paper seeks to examine the origins, antecedents ...
  • A comparison of graph colouring techniques 
    Parkinson, E; Warren, PR (South African Computer Society (SAICSIT), 1995)
    Many scheduling problems can be modelled as graph colouring problems. This paper gives a survey of heuristic algorithms used to colour graphs by describing a number of such algorithms found in the literature using an ...
  • Computer fraud in SA: an indictment of information systems 
    Messerschmidt, HJ (South African Computer Society (SAICSIT), 1995)
    There is an increasing amount of computer fraud in South Africa. A recent court case shows that Information Systems can actually assist criminals. The paper shows where the major loopholes are and suggests ways of improving ...
  • Enabling a collaborative approach to management 
    Tromp, PJ; Roode, JD (South African Computer Society (SAICSIT), 1995)
    In this paper the collaborative approach to management is examined and, in particular, how this approach could benefit from the right technological support. Collaborative management focuses on the joint performance of ...
  • A family tree of circumscriptive logics 
    Halland, KJ; Labuschagne, W.A. (South African Computer Society (SAICSIT), 1995)
    The relationships between the best-known forms of circumscription are elucidated with the aid of an hypothetical ancestor, which we choose to call naive circumscription.
  • Limitations and problems of management applications that use enterprise extensions to the SNMP MIB 
    Oosthuysen, WH; McDonald, T (South African Computer Society (SAICSIT), 1995)
    Until some years ago, management of TCP/IP based products was done in a proprietary fashion. Many large companies build their own system-wide management facilities because of a lack of usable systems to manage heterogeneous ...
  • Parallel distributed objects' structure and their synchronization in an APPC environment 
    Kisimov, V; Da Silva, I (South African Computer Society (SAICSIT), 1995)
    Over a period of a few hours, every computer participating in a distributed system has many unused resources. If these resources can be combined, a large amount of computational power can be generated. This paper offers ...
  • The recall performance of multiple associative memories - a comparison of thresholding strategies 
    Vahed, A (South African Computer Society (SAICSIT), 1995)
    The associative network presents a practical and efficient means for the storage and retrieval of data. Although the recall abilities of single-layer associative memories have been well researched [3], little investigation ...
  • Training strategies for architecture-specific recurrent neural networks 
    Ludik, J; Cloete, I (South African Computer Society (SAICSIT), 1995)
    The typical approach taken by other researchers to address the defects of standard backpropagation is to investigate alternative methods for selecting initial parameter values, or for adjusting parameter values during BP ...
  • Word frequencies in scientific prose 
    Paijmans, H (South African Computer Society (SAICSIT), 1995)
    An overview is given of popular term-weighting schemes as used in Information Retrieval. The question is raised whether the word frequency based t f.idf weights may be used as a yardstick to compare schemes that are not ...
