Statistical modelling of an ammonium nitrate fluidised bed granulator for inference measurement
(Elsevier, 2019)Fluidised bed granulation is a widely used wet granulation technique. The operation of a fluidised bed granulator (FBG) as well as the quality of the product is strongly influenced by multiple process variables and ... -
Status of astronomy in Namibia
(ICTP, 2018)Astronomy plays a major role in the scientific landscape of Namibia and Southern Africa. Considerable progress has been achieved scientifically as well as in terms of human capacity development in the field. In all ... -
Status of international interconnections and electricity deregulation in Africa: an overview of the current status in Southern Africa
(IEEE, 2004)The Southern African power system is in a state of flux. The grid is expanding and more interconnections are being made. However, vastness of the area and the low power consumption density in most African countries makes ... -
Stellar and dynamical masses of brightest cluster galaxies
(Cambridge Univ Press, 2020)We investigate the stellar and dynamical mass profiles of 32 brightest cluster galaxies (BCGs, MK = −25.7 to −27.8 mag) in massive clusters (0.05 < z < 0.30), and in particular the rising velocity dispersion profiles of ... -
Strategies for energy efficiency funding in the absence of industrial Eskom-IDM support
(IEEE, 2014)In the absence of industrial Eskom-IDM (Industrial Demand Management) funding, industry is forced to look elsewhere for energy efficiency project funding. This paper outlines various taxes and government incentives for ... -
Strengthening capacity for evidence-informed decision-making in Africa: evident lessons and opportunities
(Karger, 2017)Background and objectives: Unacceptably high rates of malnutrition in Africa persists, despite considerable knowledge and technology to address its determinants. A missing link is the access to and ... -
Stress and neurovascular coupling: a red flag? The SABPA study
(Karger, 2019)Neuronal hyperactivity mediates communication between neurons and blood vessels (neurovascular coupling) and increases susceptibility for retinal ganglion cells functionality. Contrastingly, monoamine depletion and ... -
Structuring uncertainty management for energy savings calculations
(Stellenbosch Univ, 2019)South Africa has committed itself to reducing its greenhouse gas emissions. A key strategy to minimise the greenhouse gas intensity involves using incentivised energy efficiency initiatives. In South Africa, one of these ... -
Students’ learning approaches: are they changing?
(Springer, 2017)ome researchers believe that not much has changed in terms of how students prefer to study, whilst others believe that tertiary institutions have to adapt to a new generation of students. The aim of this paper is to determine ... -
Studies of optical/gamma-ray flares of blazar 4C+01.02: recent updates from the 2016-2017 observations
(Sissa Medialab, 2017)The flat spectrum radio quasar 4C +01.02 became one of the brightest active galactic nuclei detected at high redshift (z = 2.1) in gamma rays when it underwent a series of outbursts during several months in 2016. We monitored ... -
Studies of relativistic jets in active galactic nuclei with SKA
(Sissa Medialab, 2014)Relativistic jets in active galactic nuclei (AGN) are among the most powerful astrophysical objects discovered to date. Indeed, jetted AGN studies have been considered a prominent science case for SKA, and were included ... -
A study of the loss characteristics of a single cell PEM electrolyser for pure hydrogen production
(IEEE, 2013)In this paper the losses of a proton exchange membrane (PEM) single cell electrolyser were investigated. The ohmic, activation and mass transfer losses are the most prominent losses in a PEM electrolyser. The Electrochemical ... -
Study on energy losses in industrial sector caused by low actual efficiency of induction motors
(IEEE, 2014)This paper presents a study on energy losses in the industrial sector caused by low actual efficiency of induction motors (IMs). The main reasons are discussed and an efficiency analysis of a 3-phase induction motor, ... -

Study on the energy saving applying highly efficient permanent magnet motor with two degrees of mechanical freedom in concrete industry
(IEEE-Institute of Electrical and Electronics Engineers, 2013)The cement and concrete industry in South Africa has been growing rapidly for the last couple of years. This is due to the development of the construction industry with its need in concrete products like: concrete ... -
Sunspot identification and tracking with OpenCV
(IEEE, 2020)Space weather forecasting has gained interest over the past five decades since mankind started exploring space and began using highly developed technology. Dangers such as coronal mass ejections (CME) can negatively affect ... -
A survey on reducing reconfiguration cost: reconfigurable PID control as a special case
(IFAC, 2014)Reconfigurable computing is a paradigm in computing architecture that refers to the practice of using interchangeable hardware modules to enhance the performance of conventional Von-Neumann style computing. Despite the ... -
Susceptibility of Saccharomyces cerevisiae to inhibitors and impact on bioethanol production yield
(PSRC, 2014)There have been increasing concerns in developing countries over the competition between food and energy resulting from the production of bioethanol from edible biomass. Second generation lignocellulose feedstock is an ... -
A system CFD model of the heat transfer in a prismatic block of a VHTR
(SAAM, 2018)The conduction heat transfer through the prismatic blocks containing the fuel elements in a Very High Temperature Reactor (VHTR) is of crucial importance for the proper operation of the reactor under normal operating ...
