Interactive network graphs of Biblical Hebrew data.
(Department of Ancient Studies. University of Stellenbosch, 2009)
Knowledge workers, including Biblical Hebrew computational linguists, should look into the possibilities offered by graphical visualisation techniques to allow explorative investigation of available linguistic data, since ...
Ekonometriese modelle in finansiële risiko
(AOSIS, 2008)
This paper provides an overview of the contributions by prof JH Venter to financial risk and volatility modelling, estimation and forecasting. Venter's research is based on the classical GARCH model which he refines in ...
Discovery of very-high-energy gamma-ray emission from the vicinity of PSR J1913+1011 with HESS
(EDP Sciences, 2008)
The HESS experiment, an array of four Imaging Atmospheric Cherenkov Telescopes with high sensitivity and large field-of-view, has been used to search for emitters of very-high-energy (VHE, >100 GeV) $\gamma$-rays along the ...
Constraints on the multi-TeV particle population in the Coma galaxy cluster with HESS observations
(EDP Sciences, 2009)
Aims. Galaxy clusters are key targets in the search for ultra high energy particle accelerators. The Coma cluster represents one of the best candidates for such a search owing to its high mass, proximity, and the established ...
Die skoenlusmetode: 'n kritiese oorsig
(AOSIS, 2008)
Sedert die ontstaan van die skoenlusmetodologie, het dit beide 'n kragtige versameling oplossings gebied vir die praktiese gebruiker van statistiek , sowel as 'n ryk bron van teoretiese en metodologiese oplossings vir ...
Short-period variability in the Class II methanol maser source G12.89+0.49 (IRAS 18089-1732)
(Oxford Univ Press, 2009)
Time series are presented for the Class II methanol maser source G12.89+0.49, which has been monitored for nine years at the Hartebeesthoek Radio Astronomy Observatory. The 12.2 and 6.7 GHz methanol masers were seen to ...
HESS upper limit on the very high energy gammay-ray emission from the globular cluster 47 Tucanae (Research Note)
(EDP sciences, 2009)
Observations of the globular cluster 47 Tucanae (NGC 104), which contains at least 23 ms pulsars, were performed with the HESS telescope
system. The observations lead to an upper limit of F(E > 800 GeV) < 6.7 × 10−13 cm−2 ...
The continuous depolymerization of filled polytetrafluoroethylene with a continuous process
(Wiley, 2008)
A new method for beneficiating unfilled as well as filled polytetrafluoroethylene (PTFE) waste has been developed. This process does not use any carrier gas while forming the depolymerization products. It enables polymer ...
A search for a dark matter annihilation signal toward the Canis Major overdensity with H.E.S.S.
(EDP Sciences, 2009)
A search for a dark matter (DM) annihilation signal into γ -rays toward the direction of the Canis Major (CMa)
overdensity is presented. The nature of CMa is still controversial and one scenario represents it as a dwarf ...
Predictions of gamma-ray emission from globular cluster millisecond pulsars above 100 MeV
(IOP Publishing, 2009)
The recent Fermi detection of the globular cluster (GC) 47 Tucanae highlighted the importance of modeling
collective gamma-ray emission of millisecond pulsars (MSPs) in GCs. Steady flux from such populations is also
expected ...
