  • Efficient evaluation of regular path programs 
    Wood, PT (South African Institute of Computer Scientists and Information Technologists, 1992)
    The next generation of query languages for database systems should have the ability to express recursive queries, the efficient evaluation of which will be crucial to the success of these systems. One such query language ...
  • An efficient primal simplex implementation for the continuous 2-matching problem 
    Smith, THC; Meyer, TWS; Leenen, L (South African Institute of Computer Scientists and Information Technologists, 1991)
    The continuous 2-matching problem {RMP2) is the relaxation of the symmetric travelling salesman problem {STSP) used by Padberg & Rinaldi to develop a highly successful branch-and-cut algorithm for the STSP. ...
  • Efficient shared memory multiprocessing and object-oriented programming 
    Machanick, Philip (South African Computer Society (SAICSIT), 1996)
    Object-oriented techniques are shown to hold promise for addressing the growing speed gap between memory and processors on shared-memory multiprocessors. However, reducing cache misses can be at the expense of more misses ...
  • Electronic performance support systems: appropriate technology for the development of middle management in developing countries 
    Cronje, JC; Baras Baker, SJ (South African Computer Society (SAICSIT), 1999)
    The shortage of suitably qualified middle management in South Africa, and its impact on the potential success of the RDP is well documented. There are various ways of addressing this problem. These methods range from ...
  • Enabling a collaborative approach to management 
    Tromp, PJ; Roode, JD (South African Computer Society (SAICSIT), 1995)
    In this paper the collaborative approach to management is examined and, in particular, how this approach could benefit from the right technological support. Collaborative management focuses on the joint performance of ...
  • Encryption policy for the global information infrastructure 
    Hoffman, LJ (South African Computer Society (SAICSIT), 1996)
    Cryptology policy deals not only with various technological encryption methods but also with thorny political and adminis­trative problems. It is a challenge to address these in a timely and open manner. The problems arise ...
  • Enhancing the predictability of two popular software reliability growth models 
    Keiller, PA; Mazzuchi, TA (South African Computer Society (SAICSIT), 1999)
    In this paper, enhancement of the performance of both the Musa-Okumoto and the Goel-Okumoto Software Reliability Growth models are investigated using various smoothing techniques. The method of parameter estimation for the ...
  • An enquiry into property-goal type definitions of the term "information system" 
    Mullany, M; Dos Santos Gomes, A; Miller, R (South African Computer Society (SAICSIT), 1993)
    After reference to IS authors such as Lay [7J it becomes evident that there is as yet no unified definition of the term "information system." This research has attempted to extract, from the relevant literature, the supposed ...
  • Ensuring successful IT utilisation in developing countries 
    Gardner, BR (South African Computer Society (SAICSIT), 1994)
    It is generally accepted that Information Technology (IT) has the potential to promote development and alleviate some of the common problems in the developing countries. However, it would appear that few developing countries ...
  • ESML - A validation language for concurrent systems 
    De Villiers, PJA; Visser, WC (South African Computer Society (SAICSIT), 1992)
    Designing a concurrent reactive system which can be proven correct is a challenging task. A promising technique involves building a validation model which can be shown to have important correctness properties. This paper ...
  • An Estelle compiler for a protocol development environment 
    Kritzinger, PS; van Dijk, J (South African Institute of Computer Scientists and Information Technologists, 1990)
    The development of communication protocol standards has been accompanied by the standardization of formal specification languages to describe these standards in a clear and unambiguous way. Simulta­neously, techniques for ...
  • Evaluating the motivating environment for information systems personnel in South Africa compared to the United States 
    Couger, JD; Smith, DC (South African Institute of Computer Scientists and Information Technologists, 1992)
    The South African computer industry suffers from a shortage of skilled staff. Therefore, an important management issue is to maximise the productivity and motivation of Information Systems (IS ) staff in their current and ...
  • Evaluating the motivating environment for information systems personnel in South Africa compared to the United States (Part II) 
    Couger, JD; Smith, DC (South African Computer Society (SAICSIT), 1992)
    The South African computer industry suffers from a shortage of skilled staff. To maximise the productivity and motivation of Information Systems (IS) staff in their current and future jobs is therefore an important management ...
  • The evaluation of business process reengineering projects in South Africa 
    Whittaker, L (South African Computer Society (SAICSIT), 1996)
    While much has been written describing the necessity for and effects of Business Process Reengineering (BPR), little research has been conducted into the evaluation of BPR projects. This paper describes the result of a ...
  • An evaluation of substring algorithms that determine similarity between surnames 
    De Kock, G de V; Du Plessis, C (South African Computer Society (SAICSIT), 1994)
