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 spectral opportunity in the UHF terrestrial TV frequency band
(SATNAC, 2014)In this paper an analysis to quantify the Spectral Opportunity (SO) or so-called TV white space that can be made available to White Space Devices (WSDs) as Secondary Users (SUs) of the Ultra High Frequency (UHF) terrestrial ... -
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 ... -
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 ... -
An analytical hadronic synchrotron mirror model for blazars: application to 3C279
(Sissa Medialab, 2018)On the 28th of January, the High Energy Stereoscopic System (H.E.S.S. the world’s largest ground-based gamma-ray observatory, located in Namibia) detected an orphan TeV gamma-ray flare in 3C279, not accompanied by flaring ... -
The anatomy of γ-ray pulsar light curves
(South African Institute of Physics, 2014)To obtain constraints on the inclination and observer angles, <i>α</i> and <i>ζ</i>, of a <i>γ</i>-ray pulsar from its observed light curve (LC), we make use of geometric models detailing the position and extent of emission ... -
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. ... -
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, ... -
Applying Monte Carlo methods to model multi-wavelength emission of RMHD jet simulations.
(Sissa Medialab, 2019)Relativistic jets associated with active galactic nuclei (AGN) produce radiation over a large range of the electromagnetic spectrum. While relativistic magneto-hydrodynamic (RMHD) simulations have become a powerful tool ... -
Applying RFID technology to improve efficiency in border-post cargo clearance process
(IEEE, 2013)Stakeholders in cross-border logistics and trade corridors have always been concerned about ways of improving operational efficiency. Cargo owners and cargo forwarders have been particularly concerned with long delays in ... -
Applying spontaneous adiabatic test procedure to determine CO2 gasification reactivity and kinetics of coal for UCG applications
(PCC, 2018)UCG is a gasification process used to produce synthesis gas from coal in situ (underground in the coal seam) by injecting air or oxygen, with or without steam, into coal seams and extracting the product gas via the ... -
Applying systems thinking in shaping South Africa's electricity system
(Wiley, 2014)The paper analyses the current situation in respect of South Africa's electricity situation and asks the question if Systems Thinking, more specifically as it pertains to the theory of Complex Adaptive Systems, would make ... -
An approach to improve the match-on-card fingerprint authentication system security
(IEEE, 2016)The combination of smart cards and biometrics results in a strong 2-factor authentication. It facilitates a trusted credential for authenticating an individual's identity through one-to-one biometric verification using the ... -
Aspects that need to be addressed during the development of location-based games
(Springer, 2018)To determine the suitability of a software development methodology (SDM) to aid in the development of location-based games, it is necessary to determine to what degree SDMs address certain aspects that need to be addressed ... -
Assessment of a statistical approach that facilitates the constraint of pulsar geometry via dualband light curve fitting
(Sissa Medialab, 2017)The Large Area Telescope aboard the Fermi spacecraft has detected more than 200 γ-ray pulsars since its launch in 2008. By concurrently fitting standard geometric model light curves onto Fermi and radio data, researchers ... -
Assessment of the ergonomic design of self-contained self-rescuer (SCSR) devices for use by women in mining
(SAIMM, 2020)Increasing numbers of women are entering the South African mining industry, but self-contained self-rescuer (SCSR) devices might not be suited to female anthropometric dimensions. The aim of this project was to assess ... -
Assessment of the performance of SDS-impregnated brewery waste as suitable adsorbent for the removal of Pb and Cd from water
(EARET, 2018)— Due to increasing populations and an ever-changing climate, limited water resources are South Africa’s burden. Clean water is important for all living organisms’ health and environmental sustainability. To achieve ... -
An assessment of the role of cultural factors in information security awareness
(IEEE, 2011)An information security awareness program is regarded as an important instrument in the protection of information assets. In this study, the traditional approach to an information security awareness program is extended to ...
