1996 National Research and Development Conference: Recent submissions

  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • Parallel hierarchical algorithm for identification of large-scale industrial systems 
    Jankovic, B; Bajic, VB (1996)
    Parallel execution is the most powerful method of speeding up numerical analysis. However, numerical complexity increases much faster than the problem size. For this reason the computational effort required for the analysis ...
  • 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 ...
  • 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. ...
  • Efficient state-exploration 
    Geldenhuys, J (1996)
    The exploration of states is an important element of many problems. Many problems share properties which allow the formulation of general strategies for state exploration. This article examines these strategies with reference ...
  • Teaching a first course in compilers with a simple compiler construction toolkit 
    Ganchev, GF (1996)
    We describe the use of a toolkit designed to support the Compiler Construction course in the University of Botswana. The toolkit is based upon the principles of simplicity, modularity and flexibility. Its educational ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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, ...
  • 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 ...
  • 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 ...
  • 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 ...
  • A cultural perspective on IT/End user relationships ( A description of Research in Progress) 
    Leonard, AC (1996)
    An IT/end user relationship is described as intriguing and complex and is based on a physical and abstract dimension. These two dimensions enable one to fully describe the holistic nature of such a relationship and encapsulate ...
