  • A lattice-theoretic model for relational database security 
    Melton, A; Shenoi, S (South African Computer Society (SAICSIT), 1992)
    It is often the case that a major concern with databases is security. In this paper we introduce a new model for database security. The basic idea of this new model is that answers to queries are based on equivalent data ...
  • Laws and techniques of information systems 
    Mende, J. (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    Research has a utilitarian role of providing the knowledge needed by the designers of mankind's artefacts. In this context four distinct categories of knowledge are identifiable. 1. Laws of Nature describe inherent ...
  • Learning the first step in requirements specification 
    Short, R.M.C. (Computer Society of South Africa (on behalf of SAICSIT), 1988)
    Learning about the domain into which an information system will fit is an essential part of the system development process. In this paper it is argued that the first stage of the development process should be learning ...
  • Lessons from Singapore and Zimbabwe: A model for emerging countries to achieve quality economic growth 
    Yellen, RE; Sanford, CC (South African Computer Society (SAICSIT), 1995)
    The Singapore government's adoption of policies which has promulgated an infrastructure heavily reliant on information technology is used as a model to explain Singapore's remarkable economic growth. This model helps to ...
  • Lessons learnt from an action research project running groupwork activities on the Internet: lecturers' experiences 
    Thomas, TA; Brown, S (2001)
    Group activities are important for students in order to develop the skills they will need for working with other people when they get into industry. The Internet offers an exciting environment for students to practise these ...
  • Lessons learnt from using C++ the object-oriented approach to software development 
    Mazhindu_Shumba, R (1996)
    This paper presents the lessons learned from using the C++ programming language and an object-oriented design methodology for the development of a prototype analysis tool for inheritance relationships in object-oriented ...
  • Liming-like curve constructions 
    Baart, L; McLeod, R (2000)
    R.A. Liming developed a method based on classical conic section theory to design cross-sections of aircraft using implicit rather than explicit forms of the quadratic equations. In its basic form the method is used to ...
  • Limitations and problems of management applications that use enterprise extensions to the SNMP MIB 
    Oosthuysen, WH; McDonald, T (South African Computer Society (SAICSIT), 1995)
    Until some years ago, management of TCP/IP based products was done in a proprietary fashion. Many large companies build their own system-wide management facilities because of a lack of usable systems to manage heterogeneous ...
  • A Linda solution to the evolving philosophers problem 
    Hazelhurst, SE (South African Institute of Computer Scientists and Information Technologists, 1991)
    The dining philosophers problem and the evolving philosophers problems are abstractions of resource sharing problems in parallel and distributed systems. A Linda solution to the dining problem has already been shown; this ...
  • Linear response surface analysis and some applications 
    Hattingh, JM (2000)
    In general response surface analysis refers to the modeling of experimental or observational data. Computer technology and graphical techniques obviously play a significant role in the representations of these models. A ...
  • A linear time algorithm for the longest (s-t)-path problem restricted to partial k-trees 
    Mata-Montero, M; Ellis, JA (South African Computer Society (SAICSIT), 1994)
    The Longest (s-t)-path Problem, a known NP-complete set, is shown to admit a linear time solution when the instances of the problem are restricted to partial k-trees. This class of graphs is defined and some of the properties ...
  • Local area networks in perspective 
    Kritzinger, Pieter S. (Computer Society of South Africa (on behalf of SAICSIT), 1987)
    Current scientific and trade literature are flooded with information about local area networks. Details about physical media and their properties, versions of media access methods confusingly called protocols, variations ...
  • A logic for the design of multiprogramming systems 
    Misra, J (South African Computer Society (SAICSIT), 1998)
    This paper presents a short introduction to the UNITY logic, a fragment of linear temporal logic. The logic was designed to specify safety and progress properties of reactive systems. A version of the UNITY ...
  • Logic programming: ideal vs practice 
    Labuschagne, W.A.; Van der Westhuizen, PL (South African Computer Society (SAICSIT), 1992)
    The logician who encounters logic programming expects it to involve 'using predicate logic as a programming language'. He is soon disillusioned. He discovers that it really means 'programming in PROLOG', which in tum seems ...
  • Loss probabilities for circuit-switched networks 
    Berezner, SA; Krzesinski, AE (1995)
    Consider a circuit-switched network where several source switches are connected to a destination switch via a tandem switch. Circuit-switched networks traditionally employ a Blocked Calls Cleared ( BCC) admission rule: a ...
  • Low-cost artificial intelligence research tools 
    Machanick, Philip (Computer Society of South Africa (on behalf of SAICSIT), 1986)
    There has been a proliferation of low-cost AI tools. Consideration is given as to how significant research may be conducted using these tools, in the light of experience of developing Al tools on large, expensive machines. ...
  • Low-cost medical records system: a model 
    Diani, OA; Seipone, T (1996)
    A low-cost microcomputer-based online system has been developed for the basic In-patient Medical Records functions of a General Hospital. Its basic functions are: to access patient data, register and admit a patient, enter ...
  • Machine translation from African languages to English 
    Kourie, D.G.; van den Heever, WJ; Oosthuizen, GD (South African Computer Society (SAICSIT), 1992)
    This paper describes how a machine translation system, LEXICA, has been used and adapted to translate from African languages to English. Results with Tswana provide comprehensible translations that, although not necessarily ...
  • Management aspects of client/server computing 
    Langa, S (1998)
    The purpose of the research is to investigate the management aspects of client/server computing. The latter is seen as a prerequisite for better management of all aspects of client/server computing. Noting the fact that ...
  • The Management of Operating System State Data 
    Turton, Trevor (Computer Society of South Africa (on behalf of SAICSIT), 1979)
    A new approach is proposed for the management of operating system state data. Relational database concepts are suggested for the analysis and organization of this data, and a common central service routine is described ...
