    Daar bestaan baie voorbeelde in die dataverwerkingswêreld van gebruikers wat nie die inligting vanuit huIlle rekenaarstelsels kry wat hulle nodig het nie [26]. Nuwe en onvoorsiene vrae en versoeke vir inligting neem by die ...
  • Discriminators for authorship attribution 
    Paijmans, H (South African Computer Society (SAICSIT), 1999)
    This paper describes some experiments with the automated attribution of authorship. Lexical cohesion in combination with machine learning techniques are used as a method to compare texts of different authors. A methodology ...
  • Distributed operating systems: a study in applicability 
    Prange, J; Bishop, J (South African Computer Society (SAICSIT), 1999)
    This study will attempt to show the path of research and development of a huge and currently implemented SCADA (Super­visory Control and Data Acquisition) system product. The designers and their managers have identified ...
  • Dynamic deadlock avoidance: a prototype 
    Blewett, CN; Erwin, GJ (South African Computer Society (SAICSIT), 1996)
    In this paper, we describe a prototype of an expert system software advisor for the deadlock treatment of a lock manager in a database system. The software advisor, called EAGLE (External Advisor for Granting Locks ...
  • EDI in South Africa : An assessment of the costs and benefits 
    Harrington, G (South African Computer Society (SAICSIT), 1994)
    EDI is a method of exchanging common business documentation between organisations by replacing paper transactions with electronic messages. The use of EDI can eliminate or significantly reduce the problems associated with ...
  • Effect of system and team size on 4GL software development productivity 
    Finnie, G.R.; Wittig, GE (South African Computer Society (SAICSIT), 1994)
    Modelling the effect of size on software development issues has been the object of considerable research in the software engineering community. The size metrics form an integral part of software project cost estimation ...
  • 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 ...
