• 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, ...
    • 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. ...
    • 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 ...
    • 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, ...
    • 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 ...
    • Modelling the dispersion and deposition of solid wastes from fish farming with a continuum approach 

      Fourie, Samantha-Kerry (Stellenbosch : Stellenbosch University, 2022-04)
      ENGLISH ABSTRACT: The sustainability of the environment in coastal ecosystems is of great concern due to aquaculture. There are many unknowns and constraints in the predictive modelling of fish farm waste due to the ...
    • A note on exact solutions of the logistic map 

      Maritz, Milton F (AIP Publishing, 2020-03)
      The logistic map, whose iterations lead to period doubling and chaos as the control parameter, is increased and has three cases of the control parameter where exact solutions are known. In this paper, we show that general ...
    • 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 ...
    • 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 ...
    • 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 ...
    • 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 ...
