Comparative study of steam vs hot water as primary heat transfer medium for a laboratory scale two-tank heated system
(IEEE, 2019)The need exists for a benchmark multi-domain practical system that could emulate typical process faults for the purposes of condition monitoring. A proposition was made to develop a heated two-tank system, due to its ... -
A comparative study on fault detection and correction techniques on active magnetic bearing systems
(IEEE-Institute of Electrical and Electronics Engineers, 2007)In this paper, the authors distinguish between three real-time fault detection, correction and identification schemes for vibration forces on the rotor of a rotational active magnetic bearing (AMB) system. Historical fault ... -
Comparing support vector machine and multinomial naive Bayes for named entity classification of South African languages
(PRASA, 2014)In this study, two classical machine learning algorithms, multinomial naive Bayes and support vector machines, are compared when applied to named entity recognition for two South African languages, Afrikaans and English. The ... -
Comparison analysis of AC PM transverse-flux machines of different designs in terms of power density and cost
(IEEE, 2017)This paper compares four different configurations of PM transverse-flux machines. The permanent magnet transverse flux machines with: internal rotor; outer rotor with magnetic shunts; double coil; and outer rotor without ... -
Comparison analysis of electric motors with two degrees of mechanical freedom: PM synchronous motor vs induction motor
(IEEE, 2016)This paper presents a comparison analysis of two electric motors with helical movement of the rotor. These machines are also referred to as machines with two degrees of mechanical freedom. The machines are designed in such ... -
Comparison between Flownex and CORONA thermal-hydraulic models for a single HTR prismatic fuel assembly
(ANS (American Nuclear Society), 2016) -
Comparison of astrospheres around cool and hot stars
(IOP Publishing, 2016)Simulations of astrospheres around hot and cool stars have recently move into the focus of scientific research. We describe here the differences between the astrospheres around hot and cool stars. While those around the ... -
A comparison of batch extracted bio-oil and continuous hydrothermal liquefaction bio-oil using spent coffee grounds as biomass feedstock
(EARET, 2018)This study focuses on bio-oil obtained from spent coffee grounds, either by reflux extraction or continuous hydrothermal liquefaction. Spent coffee grounds was chosen as feedstock for this study as it is available around ... -
A comparison of biodiesel purification methods
(ETA-Florence Renewable Energies, 2013)The purification of biodiesel is of cardinal importance to ensure the final product meets industry standards. This final step in the production stage contributes a large portion of the cost attributed to biodiesel production. ... -
A comparison of surface NO2 mixing ratios and total column observations at a South African site
(SASAS, 2014)The total column density nitrogen dioxide (NO2) retrievals collated by a ground-based sun-tracking spectrometer (Pandora/GSFC) and the satellite-borne (Aura) Ozone Monitoring Instrument (OMI) were compared to the volume ... -
Comparison of the modelled maximum wireless link distance for TVWS and Wi-Fi within South African regulatory constraints: which technology wins and in which scenarios?
(IEEE, 2019)The work compares Wi-Fi and television white space (TVWS) technologies for practical broadband communication links, specifically in rural areas. The paper starts with an overview of advantages and limitations of Wi-Fi and ... -
A comparison of wireless node topologies for network coding using practical path-loss models
(IEEE, 2010)In this paper, we discuss the physical arrangement of wireless nodes to form topologies suitable for the implementation of Network Coding. Boundaries for the most favorable placement of the nodes to form Bow-Tie and Butterfly ... -
Competitive intelligence: construct exploration, validation and equivalence
(Emerald, 2008)Purpose Little empirical research has been conducted on competitive intelligence (CI). This paper aims to contribute to the quantitative strand of the CI literature by exploring and validating the theoretical constructs ... -
The complex VHE and multiwavelength flaring activity of the FSRQ PKS 1510-089 in May 2015
(AIP, 2017)The blazar PKS 1510-089 was the first of the flat spectrum radio quasar type, which had been detected simultaneously by a ground based Cherenkov telescope (H.E.S.S.) and the LAT instrument on board the Fermi satellite. ... -
A comprehensive study of air quality in urban, low-income areas of South Africa
(SASAS, 2014)Multi-year ambient air quality data from 4 networks (19 sites) in Gauteng have been analyzed, in addition to data from intensive indoor and outdoor air quality monitoring in a small township in Mpumalanga province. PM10 ... -
Computational chemistry study of zirconium monomers in low acid concentration aqueous solutions
(IOP Publishing, 2018)Zirconium and hafnium have to be separated prior to their use in nuclear energy reactors. Therefore, a lot of research has been done on the solvent extraction of zirconium. However, most of this research involved screening ... -
Computational cost of an exergy-based fault detection scheme implemented in a commercial process simulator
(Elsevier, 2019)Energy-based fault detection and isolation (FDI) schemes show promise in terms of applicability to petrochemical industries and the broader process industries. Model-based FDI schemes offer pronounced advantages over more ... -
Conceptual cost of an integrated micro-algal biomass-to-liquids facility
(ETA-Florence Renewable Energies, 2011)An orderofmagnitude cost estimate was conducted on a new integrated biomasstoliquids (BtL) process that produces 2.6 million litres of biodiesel per year from microalgal biomass harvested from the Hartbeespoort Dam. ...
