  • Cooper, Antony K; Coetzee, S; Kourie, DG (ee Publishers, 2012-10)
    In this paper the authors assess two repositories of volunteered geographical information (VGI) (the 2nd South African Bird Atlas Project and OpenStreetMap) against the seven commonly-used dimensions of the quality of ...
  • Cooper, Antony K; Coetzee, S; Kaczmarek, I; Kourie, DG; Iwaniak, A; Kubik, T (AfricaGEO, 2011-05)
    The University of Pretoria in South Africa and the Wroclaw University of Environmental and Life Sciences in Poland have a joint research project under the SA/Poland Cooperation Agreement on Cooperation in Science and ...
  • Van Zyl, P; Kourie, DG; Boake, A (South African Institute for Computer Scientists and Information Technologists, 2006-10)
    The currently popular distributed, n-tiered, object-oriented application architecture provokes many design debates. Designs of such applications are often divided into logical ‘tiers’ – usually user interface, business ...
  • Duvenhage, B; Bouatouch, K; Kourie, DG (Blackwell Publishing, 2011-05)
    Backward polygon beam tracing methods, that is beam tracing from the light source (L), are well suited to gather path coherency from specular (S) scattering surfaces. These methods are useful for modelling and efficiently ...
  • Ngassam, EK; Watson, BW; Kourie, DG (2010-08)
    With this poster, the authors on the denotational semantics of algorithms to suggest an abstraction of a string recognizer. The abstraction provides a unified formalism for representing FA-based string recognizers as an ...
  • Ngassam, EK; Kourie, DG; Watson, BW (Association for Computing Machinery, 2010-10)
    Previous work on implementations of FA-based string recognizers suggested a range of implementation strategies (and therefore, algorithms) aiming at improving their performance for fast string recognition. However, an ...
  • Duvenhage, A; Kourie, DG; Hancke, GP (2009-09)
    Modelling and simulation can be applied to support Joint Command and Control (JC2) which involves the interoperability of network-centric systems as well as legacy command and control systems. It is assumed that software ...
  • Duvenhage, B; Bouatouch, K; Kourie, DG (ACM Digital Library, 2014-09)
    This paper describes a new extension to light beam tracing that includes glossy multi-bounce transport paths for more realistic rendering of caustics. A spherical Gaussian approximation of the glossy scatter distribution ...
  • Duvenhage, B; Kourie, DG (Summer Computer Simulation Conference 2007, 2007-07)
    A legacy non-distributed logical time simulator is migrated to a distributed architecture to parallelise execution. The existing Discrete Time System Specification (DTSS) modelling formalism is retained to simplify the ...
  • Cooper, Antony K; Kourie, DG; Coetzee, S (2010-10)
    Conventionally in formal concept analysis (FCA), concept stability is preferred in the lattice, because instability (i.e. low stability) represents noise that clouds the analysis of the data. However, high concept stability ...
