    The purpose of the colloquium and events centred around the central role that data plays today as a desirable commodity that must become an important part of massifying digital skilling efforts. Governments amass even ...
  • NEMISA Summit and Colloquium 2022 
    Unknown author (National Electronic Media Institute of South Africa, 2022-02-15)
    The theme for the events was "The Future of Work and Digital Skills". The 4IR caused a hollowing out of middle-income jobs (Frey & Osborne, 2017) but COVID-19 exposed the digital gap as survival depended mainly on digital ...
  • A network model for the prioritization of factors affecting software development productivity 
    Petkov, DI; Mihova-Petkova, O (1995)
    The aim of this research is to provide a new model for the prioritization of the various quantitative and qualitative factors affecting software development productivity. This is important for the evaluation of project ...
  • Network partitions in distributed databases 
    Viktor, HL; Rennhackkamp, MH (South African Computer Society (SAICSIT), 1992)
    The technology of distributed databases is based on two other technologies which have developed a solid foundation: computer networks and centralized databases. A distributed database designer should therefore address ...
  • A neural network model of a fluidised bed 
    Hajek, M (2000)
    A neural network was used to model experimental fluidisation data - bubble size and velocity - from a laboratory size fluidised bed column. Experiments were performed for several particle sizes and temperatures. A classical ...
  • 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 ...

  • A new algorithm for finding an upper bound of the genus of a graph 
    Carson, DI; Oellermann, OR (South African Computer Society (SAICSIT), 1992)
    In this paper we discuss the problem of finding an upper bound on the genus of a graph. This problem has applications to circuit layouts. An electronic circuit may be modelled by a graph. By punching holes into the circuit ...
  • A new algorithm for finding an upper bound of the genus of a graph 
    Carson, DI; Oellermann, OR (1991)
    In this paper we discuss the problem of finding an upper bound on the genus of a graph. This problem has applications to circuit layouts. An electronic circuit may be modelled by a graph. By punching holes into the circuit ...
  • A new approach for program integration 
    Bouras, Z-E; Khammaci, T; Ghoul, S (South African Computer Society (SAICSIT), 2000)
    Program integration combines independent enhancements to some version of a software system into a new system that includes the enhancements and the old system. Current approaches use the slice concept. The latter is a ...
