  • Placing processes in a transputer-based Linda programming environment 
    Clayton, Peter G.; de-Heer-Menlah, FK; Wentworth, EP (South African Computer Society (SAICSIT), 1992)
    This paper presents a process placement algorithm, designed for use in a transputer-based implementation of the Linda programming environment. A static, heuristic approach is adopted, which takes cognisance of the special ...
  • PLaVa: a lightweight persistent Java virtual machine 
    Tjasink, S; Berman, S (2000)
    This paper describes the implementation and tuning of an orthogonally persistent Java Virtual Machine (JVM) for small computers. It is based on a JVM that was targeted at a digital satellite television decoder with 1 ...
  • A pluralist systemic framework for the evaluation of factors affecting software development productivity 
    Petkova, O; Roode, JD (1998)
    pAst software development productivity research has taken two main directions: in the first, research has concentrated on determining the factors which have a significant effect on productivity; and in the second, the ...
  • A pluralistic approach to systems development 
    Lai, LSL (South African Computer Society (SAICSIT), 1995)
    It is believed that revolutionary developments in information technology may allow developing countries to leapfrog obsta­cles to development if they can successfully apply the new technology. However, many organizations ...
  • Pointers as a data type 
    Philips, N.C.K.; Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    The distinction between an abstract data type and an implementation of a data type is not as clear as is commonly thought. A hash table can be used to implement the type bag but few of our colleagues think of a hash table ...
  • Polygon shading on vector type devices 
    Scheepers, CF (1987)
    A method is presented whereby the interior of boundary-defined regions on vector type devices may be shaded using regular line, cross-hatch and dot patterns. Different shades are realized by changing ...
  • Polygon shading on vector type devices 
    Scheepers, C.F. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    A method is presented whereby the interior of boundary-defined regions on vector type devices may be shaded using regular line, cross-hatch and dot patterns. Different shades are realized by changing shading parameters ...
  • A power-order semantics for Nonmonotonic Logic I & II 
    Heidema, J; Labuschagne, WA; Meyer, TA; Rosenblatt, H (1995)
  • The practical application of a new class of 2D non-linear smoothers for digital image processing. 
    Cloete, E (1996)
    Modern applications in computer graphics and telecommunications command high performance filtering and smoothing corrections to be implemented in real-time. The recent development of a new class of non-linear smoothers for ...
  • Practical experience in running a virtual class to facilitate on-campus undergraduate teaching 
    Brown, S (1998)
    This paper discusses the current use of an Internet Education Support Program (IESP). This software package uses Internet-based tools which allows the educator to use collaborative learning techniques in both face-to-face ...
  • The practice of clausification in automatic theorem proving 
    Sutcliffe, G; Melville, S (South African Computer Society (SAICSIT), 1996)
    In the process of resolution based Automatic Theorem Proving, problems expressed in First Order Form (FOF) are transformed by a clausifier to Clause Normal Form (CNF). This research examines and compares clausifiers. ...
  • A pragmatic approach to bitemporal databases: conceptualisation, representation and visualisation 
    Njovu, C; Gray, WA (South African Computer Society (SAICSIT), 1999)
    In this paper, we describe a pragmatic approach to bitemporal data modelling, logical representation and visualisation. Our proposed approach, herein referred to as the Bitemporal Object, State and Event Modelling Approach ...
  • A pragmatic approach to development information to provide service on a wide scale 
    Mncube, SS (South African Computer Society (SAICSIT), 1996)
    The rapid technological growth in our time has produced an explosion of information. This, in tum, has spawned information systems based on the use of computers and automated systems. These mechanised devices with their ...
  • Predicting the performance of shared multiprocessor caches 
    Goosen, HA; Cheriton, DR (South African Institute of Computer Scientists and Information Technologists, 1990)
    We investigate the performance of shared caches in a shared-memory multiprocessor executing parallel programs, and formulate simple models for estimating the load placed on the bus by such a shared cache. We·analyze three ...
  • Preliminary investigation of the RAMpage memory hierarchy 
    Machanick, P; Salverda, P (South African Computer Society (SAICSIT), 1998)
    The RAMpage memory hierarchy addresses the growing concern about the memory wall - the possibility that the CPU­-DRAM speed gap will ultimately limit the benefits of rapid improvement in CPU speed. Reducing references to ...
  • Problem analysis using small problem frames 
    Jackson, MA (South African Computer Society (SAICSIT), 1998)
    The notion of a problem frame is introduced and explained, and its use in analysing and structuring problems is illustrated. A problem frame characterises a class of simple problem. Realistic problems are seen as compositions ...
  • Product form solutions for multiserver centres with hierarchical concurrency constraints 
    Krzesinski, AE; Schassberger, R (1991)
    The MultiServer centre with Hierarchical Concurrency Constraints (MSHCC) is an exponential multiserver with a queueing discipline which imposes restrictions on the number of customers of different types and subtypes that ...
  • Program Design as the Tool of Preference in Computer Literacy Education, Experience, Incentives, Implications 
    Richfield, J.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Structured program design is urged as a rewarding vehicle for the introduction of computer concepts to age groups ranging from mid primary school to senior management. Progressively expanded subsets of the material form ...
  • A program development environment for microcomputers 
    Byron-Moore, S.P. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Any distractions in the working environment can affect the quality and quantity of output. For example, noise may disturb a person's thought processes and lead to errors. In addition, the programmer is subject to other, ...
  • Programming using induction 
    Mueller, C.S.M. (South African Institute of Computer Scientists and Information Technologists, 1990)
    Induction has been used as a major tool in mathematics in proving theorems. This paper explores whether it has an equally important role in formulating programs. There are those who advocate that induction should be used ...
