Palatalisation of /s/ in Afrikaans
(Department of General Linguistics, Stellenbosch University, 2015)
This article reports on the investigation of the acoustic characteristics of the Afrikaans voiceless alveolar fricative /s/$^2$. As yet, a palatal [$\int$] for /s/ has been reported only in a limited case, namely where /s/ ...
Influence of additives on the devolatilization product yield of typical South African coals, and effect on tar composition
(SAIMM, 2018)
South African coal is mainly used for electricity generation by means of
pulverized fuel combustion and liquid fuels production via indirect
gasification technology and Fischer-Tropsch synthesis. In order to expand
the ...
Green coal development for application in fixed-bed catalytic gasification
(SAIMM, 2018)
A novel ‘green coal’ product formulation has recently been developed and
the utilization concept tested at the North-West University coal research
laboratories. Hydrothermal liquefaction was used to produce bio-oil ...
Detailed characterization of SA high mineral matter inertinite–rich coals and density fractions and effect on reaction rates with carbon dioxide: macerals, microlithotypes, carbominerites and minerals
(SAIChE, 2013)
An investigation was undertaken to determine the distribution of macerals and
minerals in South African Highveld coal deposits as well as density fractions derived from a
typical deposit. The corresponding effects on ...
Stride and translation invariance in CNNs
(Southern African Conference for Artificial Intelligence Research, 2020)
Convolutional Neural Networks have become the standard for image classification tasks, however, these architectures are not invariant to translations of the input image. This lack of invariance is attributed to the use of ...
Moisture adsorption and desorption characteristics of some South African coals
(SAIMM, 2013)
The high final total moisture content of fine coal after mining and processing is one of the major reasons that this resource is not extensively used in subsequent power generation, combustion, or other conversion processes. ...
Activity-based risk management for the acquisition of electronic mine safety equipment
(SAIMM, 2017)
A new approach is proposed to perform relativistic comparisons between
alternative operational risk management solutions by taking into account
the impact of each operational activity on overall system performance. ...
Experimentation and CFD modelling of a microchannel reactor for carbon dioxide methanation
(Elsevier, 2017)
The methanation of carbon dioxide (CO2) via the Sabatier process is increasingly gaining interest for power-to-gas application. In this investigation, a microchannel reactor was evaluated for CO2 methanation at different ...
Reducing DLOFC fuel temperatures by mixing thorium with LEU in a single-zone six-pass fuel cycle in a PBMR-DPP-400 core
(ANS (American Nuclear Society), 2016)
Many studies have been done in neutronics and thermal-hydraulic simulation of the standard 6-pass fuel recirculation scheme for the standard 9.6 wt % enriched, 9 g per fuel sphere low-enriched uranium (LEU) fuel in the ...
Gamifying the industrial engineering profession
(IEOM, 2017)
An age-old problem facing higher education institutes is the verification that the knowledge taught in class was actually learnt and internalized. Many consider that the quality of education is to be measured on this basis. ...
