  • A Comparison of Methods used to Represent Graphs on a Computer 
    Sutcliffe, Geoff (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    In general graph theorists have a limited knowledge of computers and computing, and are unaware of the possible variations of representation available, and in what circumstances which representation would be better. To ...
  • Automatic vectorization 
    Tidwell, LD; Schach, Stephen R. (South African Institute of Computer Scientists and Information Technologists, 1991)
    It is becoming increasingly difficult for researchers with little or no formal computer science background to make effective use of supercomputers and other vector machines in their own fields of research. Automatic ...
  • A Consideration of Formalisms in Computing 
    Short, R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Formalisms comprise the essential bricks and mortar that we need in order to construct information systems. Not surprisingly therefore the invention and refinement of formalisms has formed and continues to form a ...
  • Tools for Creating Tools: Programming in Artificial Intelligence 
    Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    After a brief look at how the notion of the stored program is applied by programmers in the area of Artificial Intelligence (Al), we shall look at a specific Al tool: a production svstem. The discussion is at a ...
  • A Virtual Multiprocessor Computer Design 
    Turton, Trevor (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    This paper describes computer design which 'would achieve a high instruction throughput rate on a relatively modest amount of hardware. It is based on multiprogramming the CPU at a sub-instruction level. The design will ...
  • 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 ...
  • Concurrency: An Easier Way to Program 
    Mueller, C.S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Why concurrency in itself should be seen as a method of programming, is discussed. Current approaches to concurrent programming are evaluated in terms of e~e qt programming. The properties required to decompose the ...
  • A Context Sensitive Metalanguage for Intelligent Editors 
    Kaplan, S.M. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The notion of and mot1vat1on for intelligent editor systems 1s introduced, spec1f1cally a language independent intelligent editor called "PASTOR" We also introduce and discuss the metalanguage used in the editor for grammar ...
  • Documenting a Database System with a Database 
    Hunter, D.A. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The South African Data Centre for Oceanography (SADCO) has implemented a multi d1sc1plinary oceanographic database using OMS 170, a relational database management system Using a high level query language sc1ent1sts from ...
  • Very High Speed Graphics Work-Station 
    Jablonski, J.; Dijkman, J.H. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The design of a high speed graphics workstation 1s presented A spec1f1caly designed Graphics System Interface com bines standard computer peripherals to produce a soph1st1cated man machine workstation A review 1s given ...
  • Micro-Code Implementation of Language Interpreters 
    Roets, P. P. (Computer Society of South Africa (on behalf of SAICSIT), 1982)
    An evaluation is made of the improvement of language interpreters by coding recurring sequences of instructions in micro-code. The results of an experiment with PASCAL indicate that the increase in speed expected may not ...
  • A causal analysis of job turnover among systems analysts 
    Smith, DC; Hansen, AL; Oosthuizen, NC (South African Institute of Computer Scientists and Information Technologists, 1991)
    Staff Shortages in the Information Systems industry are a continuing problem. Job turnover of IS staff contributes to this shortage and is particularly high in South Africa. This high turnover is often attributed to ...
  • Quo Vadis, Computer Science? 
    MacGregor, K.J. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    The discipline of Computer Science has been established for almost twenty years. In SOUTH AFRICA, Computer Science Departments have been in existence for fifteen years, and producing graduates for twelve, however, the ...
  • High-level Debugging Systems for Pascal: Interpreter versus Compiler 
    Hirsch, Michael; Schach, Stephen R.; Van Biljon, Willem R. (Computer Society of South Africa (on behalf of SAICSIT), 1985)
    Two approaches to high-level debugging systems for Pascal are compared, namely the use of a debugging precompiler as against a debugging interpreter. A description is given of a high-level Pascal debugging interpreter ...
  • The universal relation as a database interface 
    Philips, M.J.; Berman, Sonia (South African Institute of Computer Scientists and Information Technologists, 1991)
    The universal relation is a way of overcoming users' prime database access difficulty, namely navigation through database structures. As a result there is reduced user involvement with the underlying logical database ...
  • Specification and Performance Prediction of Fourth Generation Language Run Units 
    Wulf, S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    Fourth generation languages offer substantial productivity benefits to data processing departments. Major problems associated with their use include the inability of conventional project management systems to control ...
  • Software Configuration Management A practical approach 
    Du Preez, L.S. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    A bnef description of software conf1gurat1on management principles 1s given, followed by a d1scuss1on on the ap pl1cat1on of these principles in a spec1f1c installation
  • Syllabi for Computer Science as a Scientific Discipline 
    Postma, Stef W. (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    The paper is concerned with computer science as a science and the training required by its scientific practitioners-tobe. The background and objectives for a curriculum design are briefly sketched, and a taxonomy is given ...
  • An Adaptive Response Algorithm 
    Pirow, Peter (Computer Society of South Africa (on behalf of SAICSIT), 1984)
    In five years of watching students operate terminals I have observed that the response time of the terminal has much to do with the comfort of the user. I have also observed this phenomenon in the business environment. ...
