  • An object-oriented strategy for banking 
    Daratos, J; Steenkamp, AL (1995)
    Many information strategists today agree that the Object-Oriented Technology (OOT) has particular requirements that should not be omitted from a traditional Information Technology (IT) strategy. An Object-Oriented Strategy ...
  • OCTOLISP: An experiment with data structures 
    Dempster, Robert (South African Institute of Computer Scientists and Information Technologists, 1990)
    OCTOLISP is a functional programming language which provides the programmer with a number of explicit data structures, such as lists, stacks, vectors, sets, trees and forests. Each of these data structures also has a ...
  • On a Generalisation of Cayley Diagrams 
    Labuschagne, W.A.; Van Rooyen, H.O. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A technique for partially representing binary group operations by sets of binary relations was devised by Cayley. This technique can be generalised to permit the representation of arbitrary sets of n-ary relations {n ~ ...
  • On indexing in case based reasoning applied to pre-transportation decision making for hazardous waste handling 
    Wortmann, KL; Petkov, D; Senior, E (2000)
    Case Based Reasoning is an Artificial Intelligence technique that utilises the concept of reasoning from a stored knowledge base reflecting prior experience. It offers a number of advantages, such as learning and validation ...
  • On learning styles and novice computer use 
    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Learning to use a decision support system involves both formal and informal teaching as well as self-teaching. Many cases have been documented of unsuccesful implementation of DSS or MIS in organisations and identifying ...
  • 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 ...
  • On syntax and semantics related to incomplete information databases 
    Orlowska, ME (1987)
    We propose a mathematical model of a database with incomplete information, which we call the N-system. Basically speaking, such a system stores information concerning properties of some objects. The information may be ...
  • On syntax and semantics related to incomplete information databases 
    Orlowska, M.E. (Computer Society of South Africa (on behalf of SAICSIT), 1988)
    We propose a mathematical model of a database with incomplete information, which we call the N-system. Basically speaking, such a system stores information concerning properties of some objects. The information may be ...
  • On the generation of permutations 
    Naccache de Paz, D (South African Institute of Computer Scientists and Information Technologists, 1990)
    A new incremental algorithm for generating permutations on 1,2,..n (hereafter called "arrangements') is presented. The scheme generates arrangement k +1 by reversing a certain prefix of its predecessor and linking it to ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Opening address: Vth SA Computer Symposium 
    Viljoen, HC (South African Institute of Computer Scientists and Information Technologists, 1990)
    You may know that I am sitting on two chairs at the present moment: one, at the University of Stellenbosch in the Chair of Electronic Engineering as Dean of Engineering; the other at the SABC as chairman of the Board of ...
  • Optimal multi-splitting of numeric ranges for decision tree induction 
    Lutu, PEN (2001)
    Data mining is the process of extracting informative patterns from data stored in a database or data warehouse. Decision tree induction algorithms, from the area of machine learning are well suited for building classification ...
  • Options for development cooperation in IT education and training: the Zimbabwe case 
    Sithole, AS (1995)
    This paper attempts to address the need and justification for a Computer Skills Requirements Model for Zimbabwe as well as the findings and plans following the recently completed Zimbabwe Computer Industry Manpower Survey. ...
  • An organisational model for simplifying the complexity of managing software project 
    Zellouf, M; Prevot, P; Aubry, R (1995)
    The project success depends to a large degree on communication and coordination among team members. But project management systems and models do not support cooperative group work. Their basic philosophy is rather hierarchical ...
  • Organizational computing technologies for supporting organizational activities 
    Lochovsky, FH (South African Computer Society (SAICSIT), 1994)
    Technologies for supporting organizational activities are becoming increasingly important as a means for organizations to achieve their business goals. Such technologies allow organizations to model, execute, and control ...
  • Orthogonal axial line placement in chains and trees of orthogonal rectangles 
    Sanders, ID; Watts, DC; Hall, AD (South African Computer Society (SAICSIT), 2000)
    Previous research has shown that the orthogonal axial line placement problem for orthogonal rectangles is NP-complete in general but also that there are restrictions of the problem for which polynomial time solutions can ...
  • Orthogonal ray guarding of adjacencies between orthogonal rectangles 
    Sanders, I; Lubinsky, D; Sears, M; Kourie, D (South African Computer Society (SAICSIT), 1999)
    Guarding and covering problems have great importance in Computational Geometry. In this article the notion of' a ray guard, a guard that can only 'see' along a single ray, is introduced. The problem of siting the fewest ...
  • An overview of the Internet services available in South Africa 
    Radovanovic, A; Venter, DM (1995)
    South African networking history started in the mid 1980's. Within less than ten years, the country became the 15-th fastest growing network within the lnternet community. Today, the South African network offers a variety ...
