Activity-based risk management for the acquisition of electronic mine safety equipment
(SAIMM, 2017)A new approach is proposed to perform relativistic comparisons between alternative operational risk management solutions by taking into account the impact of each operational activity on overall system performance. ... -
As educators of teachers, where and when do our responsibilities end?
(Kamla Raj Enterprises, 2015)Quality education is a basic right of every South African learner, though despite many positive changes in the country since 1994, the legacy of low–quality education in many historically disadvantaged parts of the school ... -
Constructing a modelling-based learning environment for the enhancement of learner performance in Grade 6 mathematics classrooms : a design study
(North-West University, 2014)The purpose of this study is to focus on constructing a modelling-based learning environment to improve learner performance in grade 6 mathematics classrooms. The purpose emanates from the continued poor performance of ... -
Delevitation modelling of an active magnetic bearing supported rotor
(2014)The problem addressed in this thesis is the delevitation modelling of an active magnetic bearing (AMB) supported rotor. A system model needs to be developed that models the highly non-linear interaction of the rotor with ... -
Development of a hydrocyclone separation efficiency model using artificial neural networks
(North-West University (South Africa) , Potchefstroom Campus, 2016)A hydrocyclone is an apparatus that is widely used throughout the mineral processing industry. Usually the hydrocyclone is used for the classification, desliming or dewatering of slurries. It is inexpensive, application-efficient ... -
DFT modelling of tantalum pentafluoride extraction with phosphorus-based extractants – a molecular dynamics study
(Elsevier, 2019)Solvent extraction (SX) is a powerful method for both the separation and extraction of metals, resulting in high purity metals. The transition metals tantalum (Ta) and niobium (Nb) are of considerable significance, for ... -
The effect of feed water TDS on RO membrane rejection rates and performance
(North-West University (South Africa)., 2023)Power generation is a major user of fresh water, which is becoming important for Eskom and South Africa due to the water-scarce status. Therefore, the water usage at a thermal power station is a key metric and reverse ... -
Evaluation of predictive models for pesticide behaviour in South African soils
(North-West University, 2009)The re-evaluation of pesticide use patterns is a high priority internationally. The process has led to a reduction in the numbers of pesticides allowed for use in many countries. This withdrawal of pesticides is aimed at ... -
A FEM model for microwave absorption and heat transfer in a microwave combination washer dryer
(IEEE, 2013)Applications for the use of microwaves reach far and wide in various industries. Commonly known is the use of microwaves to heat foodstuffs. Research and development conducted in the development of a microwave combination ... -
Fermentation coupled with pervaporation : a kinetic study
(North-West University, 2011)Ethanol production through biomass fermentation is one of the major technologies available to produce liquid fuel from renewable energy sources. A major problem associated with the production of ethanol through fermentation ...
