  • The role of formalism in engineering interactive systems 
    Harrison, MD; Duke, DJ (1996)
    This paper is concerned with the role of formal notations and methods in engineering interactive systems. It begins by briefly reviewing the role of formal methods in Human Computer Interaction.The objective of capturing ...
  • 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 ...
  • The IS workers, they are a-changin' 
    Smith, D (1996)
    As changes in Information Technology and organisations move into the sophisticated areas of client/server computing and open, integrated architectures, the IS professional needs to develop an increasing range of skills and ...
  • Project management in CASE 
    Le Roux, M (1996)
    Thoughts are exchanged on Project Management in practice, specifically regarding projects analysed and systems developed with the Composer by IEF CASE tool. The information engineering methodology (IEM) that is being ...
  • The design and usage of a new Southern African Information Systems textbook 
    Erwin, GJ; Blewett, CN (1996)
    Changes in South African society have brought about changes in the background of student audiences and these have stimulated a review of the areas of governance, syllabus, curriculum, teaching methods and research in ...
  • Computer-based applications for engineering education 
    Hansen, AC; Lyne, PWL (1996)
    There is a rapidly growing awareness in the world of the need to modify the educational process at all levels of human development. In South Africa the situation is made worse by a substantial backlog in education. ...
  • A comparison of transaction management schemes in multidatabase systems 
    Renaud, K; Kotze, P (1996)
    In many applications today multiple pre-existing database systems are integrated into a single multiple database system called a multidatabase system. There are various characteristics of these systems which distinguish ...
  • A script-based prototype for dynamic deadlock avoidance 
    Blewett, CN; Erwin, GJ (1996)
    Expert systems apply Artificial Intelligence (AI) techniques to an application area, aiming (usually) to mimic the behaviour of a human expert. However, there are some AI techniques which can be used to improve the internal ...
  • Examination timetabling 
    Parkinson, E; Warren, PR (1996)
    We investigate the performance of simulated annealing and tabu search, two new general problem solving heuristics, on an examination timetabling problem. These two techniques are described here and issues arising from ...
  • Real-time control the system model - a holistic approach to system design 
    Considine, TN (1996)
    The Real-time Control System Model is a system design methodology which provides robust systems based on Object technology. The paper will detail the components of the model including the control layers and the time-based ...
  • Neural networks for process parameter identification and assisted controller tuning for control loops 
    McLeod, M; Bajic, VB (1996)
    The paper introduces a method for identification and assisted controller tuning for industrial process control loops suitable for an 'in-chip' solution. The method is based on utilization of neural network technology. It ...
  • The pearl algorithm as a method to extract information out of a database 
    Kruger, JW (1996)
    Big databases have been built up over time. The information in these databases can be converted by the Pearl algorithm [ Pearl 1988 ] from data to information. When a promotional drive is initiated, do we know who the ...
  • A reference model for the process control domain of application 
    Dhevcharran, N; Steenkamp, AL; Ram, V (1996)
    The increasing complexity of large process control systems impedes efforts to construct, co-ordinate and monitor these systems effectively. The object oriented paradigm and associated mechanisms greatly assist in software ...
  • The Independent Online: a case study of Internet publishing 
    Morris, A (1996)
    The independent online is the Internet service of Independent Newspapers, South Africa's largest newspaper group. This paper is a case study of the events of the past year, including the lessons, successes and failures ...
  • Software engineering development methodologies applied to computer-aided instruction 
    Kotze, P; De Villiers, R (1996)
    The research reported in this paper aims to integrate software engineering approaches with instructional factors in the requirements, analysis, design and production phases of instructional software development. The ...
  • A framework for executing multiple computational intelligent programs 
    Viktor, HL; Cloete, I (1996)
    Computational intelligent programs are capable of discovering interesting relationships contained in "raw" data. These programs, including artificial neural networks, set covering algorithms and decision trees, have been ...
  • Generating compilers from formal semantics 
    Venter, H (1996)
    Given a complete, formal description of the semantics of a programming language, it should be possible to generate a compiler for the language using an automated process. This is highly desirable, since it reduces the work ...
  • A validation model of the VMTP transport level protocol 
    Roux, HN; De Villiers, PJA (1996)
    The implementation of protocols can be speed up by incorporating formally validated designs in documents that describe new protocols. Unfortunately, this seldom happens in practice. It is proposed that a formally validated ...
  • COBIE: an integrated COBOL environment 
    Pillay, N (1996)
    Development software is one of the courses that first year students studying towards a Diploma in Financial Studies enrol for. This course contains an appreciable amount of RMCOBOL programming. Past experience is indicative ...
  • Feature extraction in neural networks: an application in handwritten character recognition 
    Moodley, D; Ram, V (1996)
    This paper examines and provides an overview of feature extraction techniques that are currently used in neural networks for image recognition. These include moment invariants, Zemike moments, Fourier descriptor techniques, ...
