Geometric versus kinetic modelling approach for characterizing porous metal foams
(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 nonlinear incidence rate
(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
(Journal of Machine Learning Research, 2016)Associating distinct groups of objects (clusters) with contiguous regions of high probability density (highdensity clusters), is central to many statistical and machine learning approaches to the classification of unlabelled ... 
Die fassinerende meganika van hoppende fietswiele
(LitNet, 20160526)Die gedrag van eksentriesbelaaide 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 ... 
scikitimage : image processing in Python
(PeerJ, 20140619)scikitimage 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
(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 bioeconomic application to the Cape Rock Lobster resource using a delay difference modelling approach
(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 twosex models in a stockassessment analysis. It is also true for this resource, ... 
Operations research and development
(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
(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 ...
