Cascade disruption of generation: a special focus on African grid volnurebilities
(IEEE, 2011)Large scale network disruption often lies at the heart of regional blackouts, and often disrupts entire communities in terms of their normal activities and well being. Disruptions caused by cascading failure of generating ... -
Cascade disruption of generation: the hidden gift of failure
(IEEE, 2012)Large scale network disruption often lies at the heart of regional blackouts, and often disrupts entire communities in terms of their normal activities and well being. Recognizing the threat posed by such disturbances, ... -
The case for nuclear electricity in South Africa – a political alignment framework
(Wiley, 2014)Energy is essential for economic development of South Africa. All areas for development and economic growth i.e. reducing poverty and improving quality of life require affordable access to reliable energy services. When ... -
Case study for evaluating benefits of pavement research: final results
(The National Academies of Sciences, Engineering, and Medicine, 2013)Heavy-duty pavement innovations developed through research for a major rehabilitation project in California were evaluated. The performance benefits of the innovations were examined, and the economic benefits from ... -
Case study: energy savings for a deep-mine water reticulation system
(Elsevier, 2012)In deep level mining, water reticulation systems are one of the major consumers of electricity. The refrigeration plants, together with the underground water supply and dewatering systems are integrated to form one complete ... -
Case study: the effects of a variable flow energy saving strategy on a deep-mine cooling system
(ELSEVIER, 2013)Cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water to the mine as well as cooling for mine ... -
CFD applications in the Pebble Bed Modular Reactor Project: a decade of progress
(Elsevier, 2011)Of all the systems and components that have to be designed for a nuclear plant, the Reactor Unit is the most significant since it is at the very heart of the plant. At Pebble Bed Modular Reactor (Pty) Ltd. (PBMR), the ... -
CFD modeling of particle charging and collection in electrostatic precipitators
(Elsevier, 2016)A CFD model was developed to describe the particle laden gas flow through an ESP, particle charging and collection. The corona discharge was modeled using the open source software OpenFOAM to solve the Poison and charge ... -
Characterisation of a PEM electrolyser using the current interrupt method
(Elsevier, 2014)A method is proposed to model the electrochemical characteristics of a Proton Exchange Membrane (PEM) electrolyser. The electrochemical characteristics, which include the Ohmic, activation and concentration losses, are ... -
The characterisation of slow-heated inertinite- and vitrinite-rich coals from the South African coalfields
(Elsevier, 2015)The development of coal char structures with pyrolysis has been extensively investigated but has traditionally been focused on the carboniferous coals in the northern Hemisphere. In this investigation, the properties of ... -
Characterisation tools development for PEM electrolysers
(Elsevier, 2014)Electrochemical impedance spectroscopy (EIS), current interrupt (CI) and current mapping (CM) were investigated as in-situ characterisation tools for PEM electrolysers. A 25 cm2 cell with titanium anode and carbon cathode ... -

Chemical–structural properties of South African bituminous coals: insights from wide angle XRD–carbon fraction analysis, ATR–FTIR, solid state 13C NMR, and HRTEM techniques
(Elsevier, 2015)The chemical–structural properties of four South African bituminous coals were investigated using wide angle X-ray diffraction–carbon fraction analysis (WAXRD–CFA), attenuated total reflection Fourier transform infra-red ... -
Chitosan: a low cost material for the production of membrane for use in PEMFC – a review
(Taylor & Francis, 2013)Fuel cells, especially proton exchange membrane fuel cells, are considered promising and an attractive replacement for existing sources of energy. Despite the high potential of proton exchange membrane fuel cells as an ... -
Clayey materials in river basin enhancing microbial contamination of river water
(Elsevier, 2014)Mineral constituents of clay materials may promote interaction, adsorption and attachment of microorganisms, often resulting in biofilms’ formation. In this study investigation is made to determine how littoral clayey ... -
Cloning of the cnr operon into a strain of Bacillaceae bacterium for the development of a suitable biosorbent
(Springer, 2016)In this study, a potential microbial biosorbent was engineered to improve its capacity to remediate heavy metal contaminated water resources. A Bacillaceae bacterium isolated from a mining area was transformed with ... -
Coagulation/flocculation potential of polyaluminium chloride and bentonite clay tested in the removal of methyl red and crystal violet
(Springer, 2017)This study investigated the influence of the physico-chemical properties of methyl red (MR) and crystal violet (CV) on their removal by bentonite clay and polyaluminium chloride (PACl). Different dosages of bentonite clay, ... -
