  • Scalability of the RAMpage memory hierarchy 
    Machanick, P (South African Computer Society (SAICSIT), 2000)
    The RAMpage memory hierarchy is an alternative to the traditional division between cache and main memory: main memory is moved up a level and DRAM is used as a paging device. As the CPU-DRAM speed gap grows, it is expected ...
  • Secure mobile nodes in federated databases 
    Olivier, MS (South African Computer Society (SAICSIT), 1997)
    Mobile computers pose special security risks since information contained on them can more easily be compromised. However, availability of information at the location where the mobile computer is to be used often outweighs ...
  • Selection criteria for first year Computer Science students 
    Calitz, AP; De Kock, G de V; Venter, DJL (South African Computer Society (SAICSIT), 1992)
    The evaluation of selection criteria for the admission of first year Computer Science students has been an ongoing project at the University of Port Elizabeth since 1984. Various selection criteria and methods, for example ...
  • Semantic constructs for a persistent programming language 
    Sparg, S.B.; Berman, Sonia (South African Computer Society (SAICSIT), 1992)
    Existing persistent languages cannot express the structure and semantics of the data they work on precisely and simply. As a result programs are more difficult to write and the integrity of the data is compromised. This ...
  • Shortest delay scheduling algorithm for lossless quality transmission of stored VBR video under limited bandwidth 
    Li, F; Liu, Y; Lee, JY; Ahmad, I (South African Computer Society (SAICSIT), 1999)
    In this paper, we propose scheduling algorithms for call admission control servers. For each requested video, the server sends it according to its smoothed profile aims at maximizing resource utilization and ease of network ...
  • A simulation environment for evaluating distributed query processing algorithms 
    Lamprecht, SM (South African Computer Society (SAICSIT), 1993)
    Distributed database systems provide users with the facility to utilize and maintain information that is geographically dispersed in files at several sites while they remain unaware of the distribution of the information. ...
  • Social responsibility for computing professionals and students 
    Clarke, MC (South African Computer Society (SAICSIT), 1992)
    In our desire for technical excellence, an appreciation of the human factors of computing is often overlooked. This paper proposes that the social and ethical implications of computers need to be understood by computer ...
  • Software chroma keying in an immersive virtual environment 
    Van den Bergh, F; Lalioti, V (South African Computer Society (SAICSIT), 1999)
    This paper presents a very fast software chroma keying algorithm, requiring at most five integer operations per pixel. An improvement of more than 300% in performance over HLS based algorithms was achieved. The algorithm ...
  • Some automata-theoretic properties of -NFA 
    Van Zijl, L; Van der Walt, APJ (South African Computer Society (SAICSIT), 1999)
    We prove that the shortest word accepted by an n-state intersection selective nondeterministic automaton with nonempty language can be of length O( e n log n).
  • Some current practices in evaluating IT benefits in South African organisations 
    Sutherland, F (South African Computer Society (SAICSIT), 1994)
    IT has a dynamic impact on organisations and little research has been done especially on the extent to which senior executives take the different system types into account when they appraise an IT investment. The aim of ...
  • Some typical phases of a business transformation project 
    Remenyi, D (South African Computer Society (SAICSIT), 1997)
    Business Process Reengineering (BPR) or Business Transformation is very difficult to manage successfully. There is a high failure rate of BPR projects and thus the risk associated with this type of work is high. Although ...
  • South African Computer Journal Table of Contents 
    Unknown author (2019)
  • Specialization by exclusion 
    Theron, H; Cloete, I (South African Computer Society (SAICSIT), 1994)
    This paper presents a theoretical analysis of the search schemes employed by AQ, CN2 and the recently introduced BEXA algorithm. These covering algorithms induce disjunctive concept descriptions, and employ a general-to-specific ...
  • Specific acquisition of collective belief knowledge for socially motivated multiagent systems 
    Ram, V (South African Computer Society (SAICSIT), 1998)
    Shared beliefs and knowledge are an integral part of an organisation's identity and a prerequisite for collective func­tioning. Multiagent systems that support or emulate cooperative problem solving in such a context cannot ...
  • SSDE: CASE in education 
    Norman, MJ; Berman, Sonia (South African Computer Society (SAICSIT), 1993)
    Software Engineering is a difficult and time-consuming discipline to learn. CASE Tools are generally expensive, prescriptive and tedious to use. Structured Software Development Environment (SSDE) was developed as a teaching ...
  • Statenets - an alternative modelling mechanism for performance analysis 
    Lewis, L (South African Computer Society (SAICSIT), 1992)
    Statecharts were developed by Harel to specify complex reactive systems. Statecharts proved to be rich in modelling power and convenience [9] and well suited to mechanical implementation. However, the semantic definition ...
  • Statistical analysis of an automated computer architecture learning environment 
    Waldron, JT; Horgan, J; Keogh, G (South African Computer Society (SAICSIT), 1999)
    The level of programming skill achieved by a method of learning introductory computer architecture with a strong emphasis on assembly language programming as part of a Graduate Diploma in Information Technology in the ...
  • The status of computing manpower and training in tertiary education in Southern African universities 1995 
    Bishop, JM (South African Computer Society (SAICSIT), 1996)
    The survey of staff and student numbers done in 1992 provided the first country-wide picture of computing departments in South Africa. This report presents the picture three years later, from data collected in 1995. It ...
  • A survey of information authentication techniques 
    Smuts, WB (South African Computer Society (SAICSIT), 1994)
    This article provides a survey of techniques which can be used to add authenticity to electronic documents and messages.
  • Syntactic description of neighbourhood in quadtree 
    Tapamo, JR (South African Computer Society (SAICSIT), 2000)
    Region representation is very important in Graphics and Image Processing. This paper is concerned with a formalisation of image representation by quadtrees. Indeed an image here is a language over an alphabet of four ...
