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 ... -
Catalytic hydroprocessing of ground cottonseeds in a cottonseed oil and 1-octane solvent to produce renewable diesel. (Slide presentation)
(ETA-Florence Renewable Energies, 2017) -
Cathodic protection system design framework
(IEEE, 2019)The aim of this article is to establish a cathodic protection (CP) system design framework for the petrochemical industry in South Africa. The CP system design framework is destined to be used as a guideline when designing ... -
A census of South African industrial engineers, based on data extracted from Linkedin
(SAIIE, 2014)The first South African Industrial Engineers graduated in 1963. Since then, the number of graduates per annum has grown to more than 200 per annum. Many of these Industrial Engineers use the social network, LinkedIn, to ... -
Centaurus A: hard X-ray and soft gamma-ray lightcurve correlation
(Sissa Medialab, 2017)Centaurus A (Cen A), powered by a 55 million solar mass supermassive black hole, has been intensively monitored in all accessible wavelength ranges of the electromagnetic spectrum. However, its gamma-ray flux, both in the ... -
Central stellar populations of brightest cluster galaxies
(South African Institute of Physics, 2014)We analyse the stellar populations of a sample of brightest cluster galaxies (BCGs), for which high signal-to-noise ratio, long-slit spectra were obtained on the Gemini telescopes, by fitting their spectra using the software ... -
CFD analysis of thermal dispersion in a structured packed bed
(SACAM, 2018)Packed beds are generally modelled in a partial manner to avoid computational costs. This implies that only a small portion of the representative bed is modelled explicitly in CFD simulations, usually by assuming ... -
CFD simulation of an industrial wet flue gas desulfurization spray tower: a comprehensive model with special atttention devoted to the modeling of absorption and chemical reactions
(International Pittsburgh Coal Conference, 2016) -
Challenges and issues in drug utilization research identified from the Latin American and African regions
(Wiley, 2018)Background: Despite advancements in drug utilization research (DUR), these have not been universal. Some regions such as the Latin America (LatAm) and African regions are facing challenges that are impeding the development ... -
Challenges faced by divergent ICT schools regarding branding and establishing research foci. Panel discussion held at SACLA 2010, Cullinan, 4-6 June 2010.
(2010)The audience will be informed about the process of establishing a new research niche area in a School of Information Technology situated on the Vaal Triangle Campus (VTC) of the North-West University (NWU). The School ... -
Challenges in reconciling observations and theory of the brightest high-energy flare ever of 3C 279
(PoS, 2017)Recent high-energy missions have allowed keeping watch over blazars in flaring states, which provide deep insights into the engine powered by supermassive black holes. However, having a quasar caught in a very bright ... -
Change detection in INARCH time series of counts
(Springer, 2016)In the present paper we develop an online procedure for detecting changes in the parameters of integer ARCH models of order one. The test statistic utilizes the notion of the empirical probability generating function. The ... -
Changes in body composition and cardiometabolic risk among black South African adults
(Karger, 2017)Background and objectives: Obesity-related health risk may differ by ethnicity at the same body mass index (BMI). The objectives of this study were too determine the predictive value of the World Health Organization ... -
Characterization and modelling of a customs operation
(NWU, 2018)Effective risk management is a prerequisite to find an acceptable balance between the objectives of a customs operation and the streamlined flow of goods. This requires the use of well-designed customs risk management models ... -
The characterization of the severity of rotor delevitation events: a parametric study
(s.n, 2012)Active magnetic bearing (AMB) failure and the ensuing rotor behavior is a very important aspect of AMB safety. A model for this rotor behavior was developed and was used to characterize the severity of rotor delevitation ... -
Charge-sign dependent modulation of cosmic ray electrons and positrons up to extreme solar maximum conditions
(PoS, 2017)The charge-sign dependent modulation of cosmic rays is an important topic in solar modulation studies, providing insights into gradient, curvature, and current sheet drifts. Such studies, at higher levels of solar activity, ... -
Classifying bent radio galaxies from a mixture of point-like/extended images with machine learning
(IEEE, 2016)The hypothesis that bent radio sources are supposed to be found in rich, massive galaxy clusters and the avalibility of huge amount of data from radio surveys have fueled our motivation to use Machine Learning (ML) to ...
