  • Saadeh, Emmad I.M.; Kourie, Derrick G. (World Scientific, 2013)
    The objective of this paper is to explain the notion of fine-grain transformations (FGTs), showing how they can be used as prototypical building blocks for constructing refactorings of a design-level system description. ...
  • Pieterse, H.; Olivier, Martin S.; Van Heerden, R.P. (South African Institute of Electrical Engineers, 2016-06)
    Traces found on Android smartphones form a significant part of digital investigations. A key component of these traces is the date and time, often formed as timestamps. These timestamps allow the examiner to relate the ...
  • Coetzee, Serena Martha (Springer, 2012-01)
    A grid is concerned with the integration, virtualization, and management of services and resources in a distributed, heterogeneous environment that supports virtual organizations across traditional administrative and ...
  • Coetzee, Serena Martha (Elsevier, 2011-09)
    Standardization in the field of geographic information started in the 1990s when geographic information systems (GIS) matured and the advent of the Internet accelerated the exchange of information. Recent developments, ...
  • Ngassam, Ernest Ketcha; Ntawanga, Felix; Eloff, Jan H.P. (International Center for Information Technology and Development, 2013-04)
    The need to introduce technologies in rural areas so as to capacitate communities towards overcoming various socio-economic challenges remains a priority in emerging economies. We rely on the foregoing for the investigation ...
  • Mtshali, Mbali; Engelbrecht, Andries P. (Defence Scientific Information and Documentation, 2010-01)
    In the development of mobile robotic systems, a robotic architecture plays a crucial role in interconnecting all the sub-systems and controlling the system. The design of robotic architectures for mobile autonomous robots ...
  • Gruner, Stefan (Computer Society of South Africa, 2019-12)
    On the 5th of October 2019 I browsed the ACM-DL's database with the search key 'South Africa' in the 'conference location' field such as to obtain all ACM-DL-listed conference papers which were at any time presented in ...
  • Maltese, Justin; Ombuki-Berman, Beatrice M.; Engelbrecht, Andries P. (Institute of Electrical and Electronics Engineers, 2018-02)
    Over the past few decades, a plethora of computational intelligence algorithms designed to solve multiobjective problems have been proposed in the literature. Unfortunately, it has been shown that a large majority of these ...
  • Li, Xiaodong; Epitropakis, Michael G.; Deb, Kalyanmoy; Engelbrecht, Andries P. (Institute of Electrical and Electronics Engineers, 2017-08)
    Multimodal optimization (MMO) aiming to locate multiple optimal (or near-optimal) solutions in a single simulation run has practical relevance to problem solving across many fields. Population-based meta-heuristics have ...
  • Du Plessis, M.C. (Mathys Cornelius); Engelbrecht, Andries P. (Springer, 2013)
    Despite the fact that evolutionary algorithms often solve static problems successfully, dynamic optimization problems tend to pose a challenge to evolutionary algorithms [21]. Differential evolution (DE) is one of the ...
  • Harrison, Kyle Robert; Engelbrecht, Andries P.; Ombuki-Berman, Beatrice M. (Springer, 2018-09)
    Particle swarm optimization (PSO) is a population-based, stochastic search algorithm inspired by the flocking behaviour of birds. The PSO algorithm has been shown to be rather sensitive to its control parameters, and thus, ...
  • Pamparà, Gary; Engelbrecht, Andries P. (Springer, 2018-10)
    The quantum-inspired particle swarm optimization (QPSO) algorithm has been developed to find and track an optimum for dynamic optimization problems. Though QPSO has been shown to be effective, despite its simplicity, it ...
  • Alexander, Patricia Margaret; Lotriet, H.H. (Hugo H.); Pieterse, H.V. (Computer Society of South Africa, 2014-07)
    Strong arguments exist that the sub-disciplines of Information Systems (IS) and Computer Science (CS) can be meaningfully distinguished, and the literature indicates that teams in which there are variety of personalities ...
  • Malan, Katherine M.; Eloff, Jan H.P.; De Bruin, J.A. (Jhani) (Computer Society of South Africa, 2018-07-10)
    Usability of software is a crucial aspect of successful applications and could give one application a competitive edge over another. Eye tracking is a popular approach to usability evaluation, but is time consuming and ...
  • Nicholls, Gareth; Kourie, Derrick G.; Strauss, Tinus (Computer Society of South Africa, 2009-07)
    This study examines the effects of location inaccuracies on two movement-assisted Voronoi-based sensor deployment and reconfiguration algorithms, VEC and VOR, due to Wang et al. For the purposes of examining the extent ...
  • Langeveld, Joost; Engelbrecht, Andries P. (Springer, 2012-11-29)
    Particle swarm optimization algorithms have been successfully applied to discrete- valued optimization problems. However, in many cases the algorithms have been tailored specifically for the problem at hand. This paper ...
  • Olivier, Martin S. (Vaal Triangle Faculty of Northwest University in South Africa, 2015-11)
    This essay traces two research programmes in broad strokes. Both programmes start from the same observation — the behaviour of an ant (or termite) colony and the ability of the ant colony to act in a collective manner ...
  • Mohiuddin, Mohammad A.; Khan, Salman Ahmad; Engelbrecht, Andries P. (Springer, 2014-09)
    Optimal utilization of resources in present- day communication networks is a challenging task. Rout- ing plays an important role in achieving optimal re- source utilization. The open shortest path rst (OSPF) routing ...
