Analysis of metal-laden water via portable X-ray fluorescence spectrometry
(Elsevier, 2018)A rapid method for in-situ elemental composition analysis of metal-laden water would be indispensable for studying polluted water. Current analytical lab methods to determine water quality include flame atomic absorption ... -
Analysis of PM transverse-flux outer rotor machines with different configuration
(IEEE, 2017)This paper presents the electromagnetic analysis of two permanent magnet transverse-flux outer rotor machines with and without magnetic shunts. The research started with designing and analyzing a permanent magnet transverse-flux ... -
Analysis of reaction mixtures of perhydro-dibenzyltoluene using two-dimensional gas chromatography and single quadrupole gas chromatography
(Elsevier, 2018)Energy storage via liquid organic hydrogen carrier (LOHC) systems has gained significant attention in recent times. A dibenzyltoluene (DBT) based LOHC offers excellent properties which largely solve today's hydrogen storage ... -
Analysis of reference ranges of total serum protein in Namibia: clinical implications
(MDPI, 2020)A reference range is an essential part of clinical laboratory test interpretation and patient care. The levels of total serum protein (TSP) are measured in sera to assess nutritional, liver, and kidney disorders. This ... -
Analysis of the porous structure of an annular pebble bed reactor
(Atomic Energy Society of Japan, 2009)This paper discusses the numerical analysis of the porous structure of an annular packed bed. Numerical procedures are described to determine the variation in the porosity, the variation in the coordination number (measure ... -
Analysis of the post-earnings announcement drift anomaly on the JSE
(Taylor & Francis, 2013)The post-earnings announcement drift anomaly has been widely researched and confirmed for several markets around the world. This paper investigates the relationship between the earnings surprise as reflected by the price ... -
The Analysis of the Sepedi-English Code-switched Radio News Corpus
(UP Jornals, 2022)Code-switching is a phenomenon that occurs mostly in multilingual countries where multilingual speakers often switch between languages in their conversations. The unavailability of largescale code-switched corpora ... -
An analysis of the slow compression breakage of coal using microfocus X-ray computed tomography
(Taylor & Francis, 2015)The degradation of coal and the production of coal fines during handling and transport is a serious problem in processes that depend on closely sized large particles. To minimize the production of fines, a fundamental ... -
The analysis of voltage and current unbalance by application of active and reactive power in the fundamental frequency negative-sequence components
(IEEE, 2012)The behaviour of the fundamental frequency negative-sequence power components in unbalanced power networks is evaluated for possible information on the relative contribution by the supply and loading network. Previous ... -
Analysis of waveforms in modern power systems
(Wiley, 2008)This chapter contains sections titled: Frequency Analysis of Non-Sinusoidal Waveforms: Practical Considerations; Analog-to-Digital Conversion; Sequence Component Analysis; IEEE 1459: Power Definitions for modern Power ... -
The applicability of an existing fluted tube condenser model when used with refrigerant R-407C
(Elsevier, 2013)Fluted tube-in-tube condensers are key components in energy efficient water heating heat pumps. Rousseau et al. (2003) developed a model that incorporates all the essential features of these heat exchangers. A feature ... -
Application of data analytics to transport corridor diagnostics and performance benchmarking
(IEEE, 2018)Increase in exports is essential for economic growth in developing countries. In Southern Africa the development of effective multi-national trade corridors is the single biggest stumbling block to achieve this objective. ... -
Application of exergy-based fault detection in a gas-to-liquids process plant
(MDPI, 2019)Fault detection and isolation (FDI) within the petrochemical industries (PCIs) is largely dominated by statistical techniques. Although a signal-based technique centered on exergy flows within a process plant was proposed, ... -
Application of membrane technology in a base metal refinery
(SAIMM, 2013)Nanofiltration (NF) has attracted much attention over the past few years due to the reduced energy consumption compared to reverse osmosis (RO) and better separation performance compared to ultrafiltration (UF). Although ... -
The application of modern technology in power quality management
(IEEE, 2009)Little business integration of power quality management (PQM) is forthcoming amongst electrical utilities all over Southern Africa. Restricted access to proper information is the main reason. A integration of tools, ... -
Application of nanoparticles in biofuels: an overview
(Elsevier, 2019)Biofuels are fast advancing as alternative sources of renewable energy due to their non-polluting features and cost-competitiveness in comparison to fossil fuels. However, in order to fast-track their development, focus ... -
The application of system CFD to the design and optimization of high-temperature gas-cooled nuclear power plants
(ASME, 2008)The objective of this paper is to model the steady-state and dynamic operation of a pebble-bed-type high temperature gas-cooled reactor power plant using a system computational fluid dynamics (CFD) approach. System CFD ... -
