Development of an axial suspended AMB experimental bench for load and disturbance tests
(UNAM (Universidad Nacional Autónoma de México), 2015)This paper provides the development of an axial suspended active magnetic bearing (AMB) experimental bench for load and disturbance tests. This test bench must be capable of levitating a 2 kg steel disc at a stable working ... -
Development of an integrated model for absorption of sulphur dioxide in limestone slurry
(Elsevier, 2021)The aim of this study is to develop an integrated model for SO2 absorption into limestone slurry consisting of four sub-models, namely, absorption of SO2; desorption of CO2; dissolution of limestone and crystallization of ... -
Development of efficient membrane electrode assembly for low cost hydrogen production by anion exchange membrane electrolysis
(Elsevier, 2017)Electrochemical production of hydrogen from water using anion exchange membranes (AEMs) can be achieved with non-noble catalysts, other than traditional proton exchange membranes that use platinum group metals. Using ... -
The development process of an axial active magnetic bearing
(2005)The purpose of this paper is to motivate and inspire students to investigate and understand fundamental principles of electrical engineering such as magnetic levitation, control theory and sensor design. This paper describes ... -
DFT + U studies of the electronic and optical properties of ReS2 mono-layer doped with lanthanide atoms
(IOP Publishing, 2019)The structural, electronic and optical properties of various elements in the lanthanide series as dopant atoms in the triclinic mono-layered rhenium disulphide (ReS2) structure was evaluated using density functional theory ... -

Die ontwikkeling van ’n superkapasitoraangedrewe voertuig vir die mynboubedryf
(AOSIS, 2014)The mining industry is currently looking to implement electrical vehicles into the underground tunnels of mines to reduce the amount of carbon pollution in these tunnels. This electrical vehicle is driven by an ultracapacitor ... -
Different techniques for reducing DLOFC fuel temperatures in a PBMR-DPP-400 core
(Elsevier, 2018)This article addresses the topic of modifying the fuel cycles of Pebble Bed Reactors in order to reduce their maximum fuel temperatures during Depressurised Loss of Forced Coolant (DLOFC) accidents, in order to prevent ... -
Direct liquefaction of 2 South African bituminous coal fines and their beneficiated float fractions
(EARET, 2018)The direct liquefaction of South African coal fines and their density separated (float) fractions were carried out under moderate conditions in a laboratory autoclave. The liquefaction temperature ranged between 380 and ... -
Direct metal laser sintering, using conformal cooling, for high volume production tooling
(Univ Stellenbosch, 2017)Existing techniques to manufacture conventional tool steel inserts for the plastic injection moulding process are expensive and time-consuming. Complex mould inserts, difficult to manufacture with conventional processes, ... -
A Discourse Model of Affect for Text-to-Speech Synthesis
(Pattern Recognition Association of South Africa and Mechatronics International Conference, 2013)This paper introduces a model of affect to improve prosody in text-to-speech synthesis. It operates on the discourse level of text to predict the underlying linguistic factors that contribute towards emotional appraisal, ... -
A discriminative approach to harmonic emission assessment
(IEEE, 2015)With the onset of renewable power sources onto the network, such as Photovoltaic power plants contributing to Total Harmonic Distortion (THD) in voltage, a methodology to quantify their contribution to the THD in voltage ... -
Dispersion of inorganic contaminants in surface water in the vicinity of Potchefstroom
(Elsevier, 2017)Potchefstroom and the neighbouring cities rely mostly on the Mooi River and Vaal River for their water needs. These rivers flow through the gold mining areas and farms, and are therefore likely to be contaminated with ... -
Dissolution kinetics of sorbents and effect of additives in wet flue gas desulfurization
(De Gruyter, 2014)Flue gas desulfurization (FGD) technology has been adopted by a number of power stations for the removal of sulfur dioxide (SO2) from flue gas. The wet FGD system is the most commonly used process because of high SO2 removal ... -
Dissolution kinetics of South African coal fly ash and the development of a semi-empirical model to predict dissolution
(Association of the Chemical Engineers of Serbia AChE, 2015)Wet flue gas desulphurization (FGD) is a crucial technology which can be used to abate the emission of sulphur dioxide in coal power plants. The dissolution of coal fly ash in adipic acid is investigated by varying acid ... -
DNNs as layers of cooperating classifiers
(AAAI Press, 2020-01)A robust theoretical framework that can describe and predict the generalization ability of deep neural networks (DNNs) in general circumstances remains elusive. Classical attempts have produced complexity metrics that rely ... -
