(ASSAf, 2019)Mathematics forms an integral part in the training of scientists and engineers. In recent history the South African school system has experienced several changes in school curricula. In 1994 the traditional knowledge based ... -
Comparing support vector machine and multinomial naive Bayes for named entity classification of South African languages
(PRASA, 2014)In this study, two classical machine learning algorithms, multinomial naive Bayes and support vector machines, are compared when applied to named entity recognition for two South African languages, Afrikaans and English. The ... -
Comparing the effect of modeled climatic variables on the distribution of African horse in South Africa and Namibia
(Wiley, 2015)Africa horse sickness (AHS) is a lethal disease of horses with a seasonal occurrence that is influenced by environmental conditions that favor the development of Culicoides midges (Diptera: Ceratopogonidae). This study ... -
Comparing the porosity and surface areas of coal as measured by gas adsorption, mercury intrusion and SAXS techniques
(Elsevier, 2015)In this paper, we compare the surface area, porosity and other physical–structural properties of four bituminous coals from three different coal fields of South Africa determined using carbon dioxide (CO2) and nitrogen ... -
