  • On using the situation calculus dynamically rather than temporally 
    Labuschagne, W.A.; Miller, MG (South African Computer Society (SAICSIT), 1994)
    Yet another axiomatisation of the Yale shooting scenario is provided. The point illustrated by the axiomatisation is that, when using the situation calculus to represent knowledge about a dynamic system in which actions ...
  • Teaching Pascal using multimedia 
    Jordaan, DB; Gilliland, S (South African Computer Society (SAICSIT), 1994)
    Research has shown that traditional teaching methods such as lecturing are not always as effective as the teacher or lecturer might like them to be. Frederick [3, p45] stated: 'Nearly all learning theorists.faculty development ...
  • The object-oriented paradigm: Uncertainties and insecurities 
    Schach, Stephen R. (South African Computer Society (SAICSIT), 1994)
    The object-oriented paradigm is widely promoted as the optimal way to develop software. However, there is as yet no experimental evidence to back that assertion, and it is extremely unlikely that such evidence could be ...
  • Information technology training in organisations: A replication 
    Roets, R (South African Computer Society (SAICSIT), 1994)
    This paper replicates a study conducted in the USA to test the perceived need for IT training in organisations by non-IS employees, and the need for more general business knowledge by IS employees. The hypothesis tested ...
  • Intelligent production scheduling: A survey of current techniques and an application in the footwear industry 
    Ram, V (South African Computer Society (SAICSIT), 1994)
    Computer Based Scheduling is an important activity especially in automated environments such as CIM (Computer Integrated Manufacturing ) where it is an integral part of the total manufacturing function. Developments in ...
  • Parallel execution strategies for conventional logic problems: A review 
    Lutu, PEN (South African Computer Society (SAICSIT), 1994)
    Parallel execution strategies/or Prolog programs are reviewed. Three models, AOPM, APPNet and RAP are discussed in some detail. The AOPM and the APPNet are AND-OR parallel execution models and represent the two ends of the ...
  • Ideologies of information systems and technology 
    Introna, LD (South African Computer Society (SAICSIT), 1994)
    In this paper some views and ideologies of information systems and technology will be explored. Some of these views and ideologies are clearly understood and have a high level of support. There are however more subtle ...
  • EDI in South Africa : An assessment of the costs and benefits 
    Harrington, G (South African Computer Society (SAICSIT), 1994)
    EDI is a method of exchanging common business documentation between organisations by replacing paper transactions with electronic messages. The use of EDI can eliminate or significantly reduce the problems associated with ...
  • Ensuring successful IT utilisation in developing countries 
    Gardner, BR (South African Computer Society (SAICSIT), 1994)
    It is generally accepted that Information Technology (IT) has the potential to promote development and alleviate some of the common problems in the developing countries. However, it would appear that few developing countries ...
  • Effect of system and team size on 4GL software development productivity 
    Finnie, G.R.; Wittig, GE (South African Computer Society (SAICSIT), 1994)
    Modelling the effect of size on software development issues has been the object of considerable research in the software engineering community. The size metrics form an integral part of software project cost estimation ...
  • 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 ...
  • What is information systems? 
    Crossman, T.D. (South African Computer Society (SAICSIT), 1994)
    This paper is an attempt to answer the question 'What is Information Systems?' While the characteristics of both a science and a non-science can be identified in Information Systems (IS), it is argued here that it is not ...
  • Metadata and security management in a persistent store 
    Berman, Sonia (South African Computer Society (SAICSIT), 1994)
    Since its emergence in the early eighties, persistence has become an important branch of Computer Science. Many persistent systems have now been developed and a wide variety of related issues have been well researched. Two ...
  • Markovian analysis of DQDB MAC protocol 
    Bause, F; Kritzinger, P; Sczittnick, M (South African Computer Society (SAICSIT), 1994)
    The Distributed Queue Dual Bus (DQDB) protocol or IEEE 802.6 has been accepted as the international standard for Metropolitan Area Networks (MAN). This paper describes a combined MIG/I and Markov model for the steady state ...
  • Finding All Primes Less Than Some Maximum C.C.Handley University of Natal Durban4001 
    Handley, C.C. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    The problem of finding all prime numbers less than some specified maximum is frequently set as an exercise to beginning programmers, particular students doing their first programming course at University. Several ...
  • A persistent programming language: preliminary Report 
    Berman, Sonia (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    A persistent programming language PPL is currently being designed at the University of Cape Town. The language treats persistence (permanent storage) as an orthogonal property of data and is consistent in its treatment of ...
  • A summation problem 
    Aik-Koen, Heng (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    This paper suggests a method to minimize the roundoff errors of adding N positive nimbers. The idea of construction can be easily applied to a linear recurrence process.
