  • 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 ...
  • The P-NP Question and Recent Independence Results 
    Philips, N.C.K. (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    Despite intensive research the P = NP question is unresolved and the research suggests thatitis hard to answer. The corresponding question for query machines with recursive oracles is undecidable in set theory. Simply ...
  • The parallel conditional 
    Postma, Stef W.; Philips, N.C.K. (S W Postma and N C K Phillips (1988) The parallel conditional. Computer Society of South Africa (on behalf of SAICSIT), 1988)
    The parallel conditional is a new but natural programming language construct. It is particularly suited to evaluation on parallel maclunes and generalizes other well known conditionals.
  • 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 ...
  • 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 ...
  • Parallel hierarchical algorithm for identification of large-scale industrial systems 
    Jankovic, B; Bajic, VB (1996)
    Parallel execution is the most powerful method of speeding up numerical analysis. However, numerical complexity increases much faster than the problem size. For this reason the computational effort required for the analysis ...
  • Parallelism: an effective genetic programming implementation on low-powered mathematica workstations 
    Suleman, H; Hajek, M (1996)
    Mathematica has proven itself to be a suitable platform on which to develop prototype Genetic Programming applications. However, due to the sheer complexity of genetic programming calculations, non-trivial problems cannot ...
  • Partial edge visibility in linear time 
    Bilbrough, J; Sanders, I (1998)
    This research addresses the problem of partial edge visibility. This problem stems from work done in the ray guarding of configurations of adjacent rectangles [7]. In ray guarding these configurations it is necessary to ...
  • A partial RJE pad specification to illustrate LOTOS 
    Kourie, D.G. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    LOTOS (Language Of Temporal Ordering Specification) is employed to give a partial specification of a system to connect RJE devices across an X.25 network. The system's implementation has been described fully elsewhere ...
  • A partitioning scheme for solving the exact K-item 0-1 knapsack problem 
    Kruger, MF; Hattingh, JM (1998)
    Our investigation on the impact of partitioning the search space of the classical 0- 1 Knapsack Problem through the inclusion of equality constraints on the knapsack's cardinality, has given rise to the study we undertook ...
  • A pattern architecture: using patterns to define an overall systems architecture 
    Van Zyl, J; Walker, AJ (2001)
    The notion of patterns has been used in many different disciplines, and the software industry is no exception. There are many books written, academic research done and practical examples available of where patterns have ...
  • Paying for high speed network services 
    Smuts, WB (1995)
    The real-time services offered by modern high speed networks are complex enough to prompt a new look at how these services should be paid for. In this article, it is motivated that paying for the use of guaranteed services ...
  • The pearl algorithm as a method to extract information out of a database 
    Kruger, JW (1996)
    Big databases have been built up over time. The information in these databases can be converted by the Pearl algorithm [ Pearl 1988 ] from data to information. When a promotional drive is initiated, do we know who the ...
  • A performance analyser for the numerical solution of general Markov chains 
    Knottenbelt, W; Kritzinger, P (South African Computer Society (SAICSIT), 1998)
    Despite many advances in queueing theory and other modelling paradigms, one persistenty discovers real life stochastic systems which do not yield neatly to existing methods for their performance analysis. In most such ...
  • 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 ...
