A generalized additive neural network application in information security
(Tadbir Operational Research Group, 2014)Traditionally spam has been considered as an inconvenience requiring workers to sift through and delete large numbers of e-mail messages per day. However, new developments and the Internet have dramatically transformed the ... -
A generic approach to integrating energy related data
(IEEE, 2014)The energy management processes of mines and industrial plants differ because of the specialised processes used for mining or production. Therefore, energy management systems typically provide users with specialised tools ... -
Genetic algorithm based PID tuning for optimal power control of a three-shaft Brayton cycle based power conversion unit
(Elsevier, 2012)This paper considers the development of a PID control strategy to optimally control the power output of a High Temperature Gas-cooled Reactor (HTGR) power plant. A specific type of HTGR called the Pebble Bed Modular Reactor ... -
Geometric modelling of radio and γ-ray light curves of 6 Fermi LAT pulsars
(Sissa Medialab, 2010)The Fermi Large Area Telescope (LAT) has recently reported the detection of pulsed γ-rays from 6 young pulsars (J0631+1036, J0659+1414, J0742−2822, J1420−6048, J1509−5850, and J1718−3825), all exhibiting single-peaked ... -
Geometry based analysis of an alternative RFID interrogator placement for electronic vehicle identification
(IEEE, 2015)This paper proposes a solution for reliable in-traffic electronic vehicle detection based on UHF passive RFID (ISO/IEC 18000-63 - UHF Type C). The classic overhead placement of an interrogator reading a windscreen or plate ... -
The global galerkin finite element method as applied to the 1d beam equation: a systems approach
(SAAM, 2006)The paper focuses on the finite element solution of the fourth-order differential for an EulerBernoulli beam. In this approach the point point loads and concentrated moments are treated in a natural way as part of the ... -
A global view of the modulation of cosmic ray protons in the heliosphere for the solar minimum period up to 2009
(IOP Publishing, 2016)The heliosphere was in a state of ideal solar minimum conditions for at least three years up to the end of 2009. During this period the highest ever recorded cosmic ray spectra were observed at the Earth. Fortunately, the ... -
Glow-in-the-dark globular clusters: modelling their multiwavelength lanterns
(South African Institute of Physics, 2012)Globular clusters (GCs) are astronomical tapestries embroidered with an abundance of exotic stellar-type objects, including ancient metal-poor stars, planetary nebulae, white dwarfs (WDs), low-mass X-ray binaries (LMXRBs), ... -
Graph matching as a means to energy-visualisation of a counter-flow heat exchanger for the purpose of fault diagnosis
(Elsevier, 2017)Energy is a holistic way of analysing multi-domain systems. By using energy, system information can be reduced to essential or dominant dynamics. This could be advantageous for the purpose of fault diagnosis. In this paper, ... -
GRB observations with H.E.S.S.
(Sissa Medialab, 2019)Fermi-LAT observations have proven that GeV γ-ray emission is a relatively common feature for many Gamma Ray Bursts (GRB). However the low effective area of space detectors implies low statistics for high-energy photons ... -
GRB observations with H.E.S.S. II
(PoS, 2017)The High Energy Stereoscopic System (H.E.S.S.) has been searching for counterparts of Gamma Ray Bursts (GRBs) for many years. In 2012 the system was upgraded with a fifth 28m diameter telescope (CT5) which is equipped ... -
Green IS management framework verification: explicating the enabling capabilities of green IS
(BIS-Verlag, 2014)The first objective of the paper is to expose the Green Information Systems (Green IS) management framework comprising the enabling capabilities of Green IS, moderating concepts, and relationships to environmental ... -
Guidelines for the design and creation of a web form to facilitate the registration of first time tax payers: an HCI approach
(IBIMA, 2010)Research has been conducted both in the field of Human-Computer Interaction and in the field of design and creation. Very little research has been conducted in the area of tax registration systems. No research was carried ... -
H.E.S.S. discovery of very-high-energy gamma-ray emission of PKS 1440-389
(Sissa Medialab, 2015)Blazars are the most abundant class of known extragalactic very-high-energy (VHE, E>100 GeV) gamma-ray sources. However, one of the biggest difficulties in investigating their VHE emission resides in their limited number, ... -
The H.E.S.S. II GRB observation scheme
(AIP, 2017)Gamma-ray bursts (GRBs) are some of the Universe’s most enigmatic and exotic events. However, at energies above 10 GeV their behaviour remains largely unknown. Although space based telescopes such as the Fermi-LAT have ... -
Hard spectral tails in magnetars
(Cambridge Univ Press, 2017)Pulsed non-thermal quiescent emission between 10 keV and around 150 keV has been observed in ~10 magnetars. For inner magnetospheric models of such hard X-ray signals, resonant Compton upscattering of soft thermal photons ... -
Hard X-ray quiescent emission in magnetars via resonant Compton upscattering
(IOP Publishing, 2017)Non-thermal quiescent X-ray emission extending between 10 keV and around 150 keV has been seen in about 10 magnetars by RXTE, INTEGRAL, Suzaku, NuSTAR and Fermi- GBM. For inner magnetospheric models of such hard X-ray ... -
Harmonic emission assessment on a distribution network: the opportunity for the prevailing angle in harmonic phasors
(IET, 2017)Harmonic emission assessment in high-voltage networks with a number of renewable power plants (RPP) interconnected is challenging. A sound scientific methodology readily accessible to engineers is needed to validate ... -
Harmonic impedance assessment using prevailing phasors
(IEEE, 2018)In accordance with the IEC 61000-3-6, the evaluation of the harmonic emissions requires an accurate harmonic impedance representation of the system. However, the assessment of a harmonic impedance is understood to be a ...
