Magnetic circuit analysis of the low-cost in-wheel switching flux motor for HEV applications
(IEEE, 2019)This paper presents the design and analysis of Permanent Magnet Switching Flux Motor (PMSFM) for hybrid electrical vehicle application. The design is intended to obtain a cost effective, efficient motor with small flux ... -
Maize (Zea mays L.) fresh husk mediated biosynthesis of copper oxides: potentials for pseudo capacitive energy storage
(Elsevier, 2019)Copper oxide nanoparticles were synthesized using an eco-friendly, simple and cost effective green synthesis method mediated by maize (Zea mays L.) fresh husk extract. Pure reddish cubic Cu2O nanoparticles were obtained ... -
Manipulation of the ash flow temperature and viscosity of a carbonaceous Sasol waste stream
(Elsevier, 2010)In 2001 Sasol investigated the possibility to convert a Sasol-Lurgi MK III fixed bed dry bottom coal gasifier at the former Sasolburg coal-to-liquids plant to a slagging gasification process and selected the Lurgi Multi ... -
Manufacturing and testing of briquettes from inertinite-rich low-grade coal fines using various binders
(SAIMM, 2018)Inertinite-rich, low-grade coal was used with 12 binders: clays (attapulgite and bentonite), biochar, cow dung, crystallized medium-tar pitch, coal tar sludge, flocculant, fly ash, lignosulphonates, polyester resin, and ... -
Manufacturing of briquettes from typical highveld coal fines using various binders

Math hydrogen catalytic recombiner: engineering model for dynamic full-scale calculations
(Elsevier, 2018)To protect a hermetic enclosure and the equipment and systems of a reactor installation housed in it from damage caused by the ignition (explosion) of hydrogen, most nuclear power plants with pressurized water reactors are ... -
Mathematical methodology and software package for investigation of nonstationary hydrogen permeability in membranes used in electrolysers and hydrogen fuel cells
(Elsevier, 2017)As part of the methodology to control gas permeability of functional materials, mathematical approach is considered that takes into account a diffusion process through a plate with the boundary conditions of the 1st and ... -
Maximum leave-one-out likelihood for kernel density estimation
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2010)We investigate the application of kernel density estimators to pattern-recognition problems. These estimators have a number of attractive properties for data analysis in pattern recognition, but the particular characteristics ... -
Measurement and verification baseline development and service level adjustments for fridge plant systems
(2009)In this article the authors provide an overview of a fridge plant system and discuss the data requirements and data selection for baseline development. The baseline development is divided into two scenarios: 1) where ... -
Measurement and verification of a lighting load reduction project through energy efficiency
(2009)This paper will describe the methodology and procedures that were followed to measure and verify the impact on the electricity use of a lighting load reduction project implemented at a gold mine. The lighting retrofit ... -
Measurement and verification of irrigation pumping DSM projects: application of novel methodology designs
(Univ Cape Town, Energy Research Centre, 2016)In South Africa the agricultural sector is a significant energy user, with irrigation pumping being the single biggest electricity-demanding farming activity. The agricultural and commercial sectors contribute 6.5% to ... -
Measurement and verification of load shifting interventions for a fridge plant system in South Africa
(ERC (Energy Research Centre), 2013)In this paper, the author presents the measurement and verification methodology used to quantify the impacts of load shifting measures that are implemented on large industrial fridge plant systems in South Africa. A summary ... -
Measurement and verification of the Eskom irrigation pumping standard product programme
(2013)Eskom Integrated Demand Management (IDM) initiated a funding mechanism termed the Standard Product Programme (SPP) to cater for smaller Energy Efficient (EE) projects. The impacts of these projects also need to be assessed ... -
Measurement and verification of the Eskom irrigation pumping standard product programme: evaluation of crop load factors
(2013)Eskom Integrated Demand Management (IDM) also included irrigation in the Standard Product Programme (SPP) to cater for smaller irrigation Energy Efficient (EE) projects. The irrigation sector is a large energy consumer ... -
Measurement uncertainty of current harmonics during the assessment of compliance to grid code requirements
(IEEE, 2018)This paper improves the impact of measurement uncertainty on harmonic grid code compliance assessment by characterization of the current transformers at a renewable power producer. Field data was collected to evaluate the ... -
Mechanical and thermal characterization of briquetted high ash South African coal fines using low density polyethylene as the binding agent
(International Pittsburgh Coal Conference, 2016) -
The mechanism by which moderate alcohol consumption influences coronary heart disease
(BioMed Central, 2015)Background Moderate alcohol consumption is associated with a lower risk for coronary heart disease (CHD). A suitably integrated view of the CHD pathogenesis pathway will help to elucidate how moderate alcohol consumption ... -
The mechanisms by which antidepressants may reduce coronary heart disease risk
(BioMed Central, 2015)Background Depression is known to increase the risk for coronary heart disease (CHD) likely through various pathogenetic actions. Understanding the links between depression and CHD and the effects of mediating these links ... -
Medium-vocabulary speech recognition for under-resourced languages
(SLTU, 2012)We report on the development of speech-recognition systems that are able to perform accurate recognition on mediumvocabulary tasks (i.e. tasks that require distinctions between approximately 200 different terms). We are ...
