Performance analysis of a permanent magnet transverse flux generator with double coil
(IEEE, 2016)
One of the disadvantages of permanent magnet (PM) transverse flux machines is high magnetic flux leakage in the stator and rotor
cores. To improve the magnetic circuit of this class of machines, a generator with double ...
The application of a resilience assessment approach to promote campus environmental management: a South African case study
(Emerald, 2016)
Purpose - This paper aims to outline the benefits of using resilience assessment instead of command and control mechanisms to evaluate sustainable campus environments. Design/methodology/approach - An exploratory mixed-method ...
Three-year changes of prothrombotic factors in Africans with a high clinical suspicion of obstructive sleep apnea
(Schattauer Publishers, 2016)
A hypercoagulable state might be one important mechanism linking obstructive sleep apnea (OSA) with incident myocardial infarction and stroke. However, previous studies on prothrombotic factors in OSA are not uniform and ...
Restricting the marketing of foods and non-alcoholic beverages to children in South Africa: are all nutrient profiling models the same?
(Cambridge Univ Press, 2016)
The WHO has called for governments to improve children’s food environment by implementing restrictions on the marketing of ‘unhealthy’ foods to children. Nutrient profiling (NP) models are used to define ‘unhealthy’ foods ...
Management of learner discipline in secondary schools: a collaborative effort
(Kamla-Raj, 2016)
The focus of this paper is on the management of the learner discipline in the secondary schools. Two
secondary schools were sampled for data collection. A qualitative research design was used engaging four focus
group ...
Student ranking by means of non-linear mathematical optimization of participation marks
(ORLab Analytics, 2016)
Ranking students according to their growing participation marks could encourage them to develop self-motivational attitudes toward their academic progress. This paper describes the ranking of students by means of a non-linear ...
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 ...
The effect of particle size on the rate and depth of moisture evaporation from coal stockpiles
(SAIMM, 2016)
Excessive amounts of moisture in product coal can influence the efficiency
of downstream utilization processes due to a decreased calorific value and
handling problems. Stockpiles can be used to decrease the moisture
content ...
CNF-supported platinum electrocatalysts synthesized using plasma-assisted sputtering in pulse conditions for the application in a high-temperature PEM fuel cell
(ESG, 2016)
Nanostructured platinum catalysts for a high-temperature proton-exchange membrane (PEM) fuel cell based on polybenzimidazole (PBI) doped by H3PO4 were synthesized by magnetron-ion sputtering of platinum on carbon nano-fibers ...
