  • Non-orthogonal ray guarding 
    Sanders, I (1998)
    In an earlier paper the notion of a ray guard --'- a guard that can only see along a single ray, was introduced. The ray guarding problem is in siting the fewest possible such guards so that they guard all adjacencies ...
  • Novice attitude changes during a first course In computing: a case study 
    Finnie, G.R. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    This paper describes a study of changes in attitude toward computers exhibited by novice student users during a first course in business computing. Several dimensions of attitude were established by factor analysis. ...
  • Novice researchers' perspectives on affordances in ICT4D research collaboration 
    Mwapwele, Samwel; Van Biljon, Judy (John Wiley & Sons Ltd, 2021)
    Collaboration is fundamental to progress in the field of information and communication technologies for development (ICT4D) research where interdisciplinary teams are involved in the requirements elicitation, design, ...
  • The NRDNIX distributed database management system 
    Rennhackkamp, MH (South African Institute of Computer Scientists and Information Technologists, 1990)
    A distributed database management system must facilitate integrated processing of data which is physically distributed over a network of node computers, while providing locality transparency. The NRDNIX prototype has ...
  • Object orientation in relational databases 
    Rennhackkamp, M (1991)
    There is, as yet, no single formal definition for the object-oriented approach. The object-oriented paradigm is described in terms of the concepts accentuated by the approach, namely classes, objects, methods, messages and ...
  • Object oriented database management systems 
    Nassis, Antonios (1995-11)
    Modern data intensive applications, such as multimedia systems require the ability to store and manipulate complex data. The classical Database Management Systems (DBMS), such as relational databases, cannot support these ...
  • Object oriented programs and a stack based virtual machine 
    Waldron, JT (South African Computer Society (SAICSIT), 2000)
    Dynamic quantitative measurements of Bytecode and Stack Frame Usage by Eiffel and Java Programs in the Java Virtual Machine are made. Two Eiffel programs are dynamically analysed while executing on the JVM, and the results ...
  • Object-oriented business modelling and re-engineering 
    Watzenboeck, M (2000)
    Financial industry and manufacturing are the main customers in migrating existing applications into client server environments. This paper helps in identifying the candidates for migration and suggests a method for ...
  • Object-oriented development: knowledge base support for design 
    Loock, M; Steenkamp, AL (1995)
    The research is conducted in the area of Software Engineering, with emphasis on the design phase of the Software Development Life Cycle (SDLC). The object-oriented paradigm is the point of departure. The investigation deals ...
  • An object-oriented framework for rapid client-side integration of information management systems 
    Schimkat, RD; Kuchlin, W; Krautter, R (South African Computer Society (SAICSIT), 1999)
    Reuse of software components offers the potential for significant savings in application development costs and time. This paper provides a characterization of reuse at different levels of client-based software in distributed ...
  • 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 ...
  • 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 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 ...
