  • The evaluation of business process reengineering projects in South Africa 
    Whittaker, L (South African Computer Society (SAICSIT), 1996)
    While much has been written describing the necessity for and effects of Business Process Reengineering (BPR), little research has been conducted into the evaluation of BPR projects. This paper describes the result of a ...
  • An evaluation of substring algorithms that determine similarity between surnames 
    De Kock, G de V; Du Plessis, C (South African Computer Society (SAICSIT), 1994)
    The problem investigated in this study is, given a surname, determine similar surnames in a genealogical database. There exist a number of algorithms to determine the similarity between two strings based on their common ...
  • An evaluation of the skill requirements of entry-level graduates in the information systems industry 
    Smith, DC; Newton, S; Riley, MJ (South African Computer Society (SAICSIT), 1992)
    Information Systems (IS), although a relatively new academic discipline, is receiving considerable attention in tertiary institutions in South Africa. Despite this, there is currently no standard curricula for IS graduates ...
  • Expert systems for management control: A multi-expert architecture 
    Ram, V (South African Computer Society (SAICSIT), 1993)
    The use of Expert Systems technology in management decision making domains is increasing rapidly as business environments worldwide grow more turbulent and as the cost of development tools decrease. Research effort in this ...
  • An exploratory study into communications between IS staff and users during requirement specification 
    Du Plessis, CJ; Rip, SDE; Lay, PMQ (South African Institute of Computer Scientists and Information Technologists, 1990)
    Communication between IS staff and users during requirement specification is unavoidable. However, little research has been conducted to explore the relationship between effective group communication and the quality of the ...
  • Extending local recovery techniques for distributed databases 
    Viktor, HL; Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1992)
    The most frequently used local database system failure recovery techniques are logging , shadowing and differential files. In a distributed database these local system failure recovery techniques may be·utilized for recovery ...
  • 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.
  • A file server for a multi-transputer UNIX system 
    Hoffman, PK; Smit, G de V (South African Institute of Computer Scientists and Information Technologists, 1990)
    The DISTRIX operating system is a multiprocessor UNIX-like distributed operating system. It consists of a number of satellite processors connected to central servers. The system is based on the MINIX operating system, ...
  • Finding regular paths in acyclic graphs 
    Wood, PT (South African Institute of Computer Scientists and Information Technologists, 1990)
    Increasing the expressive power of relational query languages by providing some form of recursion is currently a topic of much research. For many recursive queries in relational databases, a relation can be represented ...
  • The fixpoint theorem in the El-Calculus 
    Postma, SW; McGee, A (South African Institute of Computer Scientists and Information Technologists, 1990)
    The οr.1-calculus is presented as an extension to the standard 1-calculus, and a r.1-term called the strong conditional is discussed. The strong conditional is shown to be non-monotomic, and an extension is made to the ...
  • A formal model for object bases 
    Patsouris, PA; Korostenski, M; Kissimov, V (South African Computer Society (SAICSIT), 1999)
    We introduce FMOB: a formal model for Objectbases. The term "Objectbase" represents better the widely used "object­ oriented database". FMOB consists of ( 1) objects (classes and their instances) with extended encapsulation ...
  • Formal verification with natural language specifications: guidelines, experiments and lessons so far 
    Holt, A (South African Computer Society (SAICSIT), 1999)
    The industrial take-up of formal verification techniques remains limited. Allowing specifications to be expressed in natural language (perhaps augmented with diagrams) offers the prospect of increasing the usability of ...
  • Four major success criteria for information system design 
    Mende, J. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Both in the advancement of Information Systems theory and in practical development projects, significant errors of omission can occur unless one is aware of all aspects of the concept "information system success". At least ...
  • Fractal image compression 
    Cloete, E; Venter, LM (South African Computer Society (SAICSIT), 1998)
    Conventional image compression strategies present a number of uncomfortable limitations. Many of the impediments can be overcome by Fractal Image Compression (FIC). FIC is rooted strongly in mathematics. In comparison to ...
  • The FRD Special programme on collaborative software research and development. Draft call for proposals 
    Krzesinski, T (South African Computer Society (SAICSIT), 1994)
    The foundation for Research Development (FRD) is evaluating the need for a new Special Programme in Computer Science. An initial meeting was held in August 1993 at the FRD to discuss the new programme. A Steering Committee ...
  • From batch to distributed image processing: remote sensing for mineral exploration 1972-1992 
    Pendock, N (South African Computer Society (SAICSIT), 1992)
    The routine use of satellite remotely sensed imagery for a variety of applications is twenty years old this year. In addition to these digital photographs of the earth's surface, subterranean views are made using gravity, ...
  • From information security baselines to information security profiles 
    Von Solms, R; Van de Haar, H (South African Computer Society (SAICSIT), 1999)
