  • Geometric versus kinetic modelling approach for characterizing porous metal foams 

    Mare, Esmari; Woudberg, Sonia (WIT Press, 2019)
    Knowledge of the geometric and kinematic parameters of porous foams are of great importance since it is used in a wide variety of industrial multiphase flow applications that require optimal functionality, e.g. gas filters, ...
  • Computational modelling and optimal control of Ebola virus disease with non-linear incidence rate 

    Takaidza, I.; Makinde, O. D.; Okosun, O. K. (IOP Publishing, 2017)
    The 2014 Ebola outbreak in West Africa has exposed the need to connect modellers and those with relevant data as pivotal to better understanding of how the disease spreads and quantifying the effects of possible interventions. ...
  • Minimum density hyperplanes 

    Pavlidis, Nicos G.; Hofmeyr, David P.; Tasoulis, Sotiris K. (Journal of Machine Learning Research, 2016)
    Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is central to many statistical and machine learning approaches to the classification of unlabelled ...
  • Die fassinerende meganika van hoppende fietswiele 

    Theron, Willem; Maritz, Milton (LitNet, 2016-05-26)
    Die gedrag van eksentries-belaaide wiele of hoepels het tydens die afgelope twee dekades aandag geniet, veral met betrekking tot sulke wiele se geneigdheid om te hop. Hier word ’n oorsig gegee oor die verskillende aspekte ...
  • scikit-image : image processing in Python 

    Van der Walt, Stefan; Schonberger, Johannes L.; Nunez-Iglesias, Juan; Boulogne, Francois; Warner, Joshua D.; Yager, Neil; Gouillart, Emmanuelle; Yu, Tony (PeerJ, 2014-06-19)
    scikit-image is an image processing library that implements algorithms and utilities for use in research, education and industry applications. It is released under the liberal Modified BSD open source license, provides a ...
  • Offline signature verification using the discrete Radon transform and a hidden Markov model 

    Coetzer, J.; Herbst, B. M.; Du Preez, J. A. (Hindawi, 2004)
    We developed a system that automatically authenticates offline handwritten signatures using the discrete Radon transform (DRT) and a hidden Markov model (HMM). Given the robustness of our algorithm and the fact that only ...
  • A bio-economic application to the Cape Rock Lobster resource using a delay difference modelling approach 

    Roos, E. (Operations Research Society of South Africa, 2004)
    In many species, like the Cape Rock Lobster (Jasus lalandii), the life cycles of males and females differ. This may motivate the use of two-sex models in a stock-assessment analysis. It is also true for this resource, ...
  • Operations research and development 

    Fourie, P. (Operations Research Society of South Africa, 2007)
    The paper begins with a discussion of the concepts “operations research” and “development.” An overview is next given of the RDP (Reconstruction and Development Programme), which still embodies the vision of development ...
  • On the(d)–chromatic number of a complete balanced multipartite graph 

    Burger, A. P.; Nieuwoudt, I.; Van Vuuren, J. H. (Operations Research Society of South Africa, 2007)
    In this paper we solve (approximately) the problem of finding the minimum number of colours with which the vertices of a complete, balanced, multipartite graph G may be coloured such that the maximum degrees of all colour ...
