Estimates for very high energy gamma rays from globular cluster pulsars
(AIP, 2008)
Low‐Mass X‐ray Binaries (LMXRBs), believed to be the progenitors of recycled millisecond pulsars (MSPs), occur abundantly in globular clusters (GCs). GCs are therefore expected to host large numbers of MSPs. This is also ...
Unraveling the emission geometry of the Fermi millisecond pulsars
(Fermi, 2009)
The nine millisecond pulsars (MSPs) that have now been detected by Fermi-LAT are providing
an excellent opportunity to probe the emission geometry of these ancient compact objects. As they
are radio-loud, one may use the ...
Constraints on the lepton content of PWN from the local CR positron spectrum
(ICRC, 2008)
Geminga is a nearby pulsar with an age of 3.42×105
yr and a spindown power of 3.2×1034
erg/s at present. B0656+14 has comparable spindown power, with an age of 1.11×105
yr and a distance
of 290 pc. The winds of these ...
Search for pulsed VHE gamma-ray emission from young pulsars with H.E.S.S.
(ICRC, 2008)
We present the results of a search for pulsed very-high-energy (VHE) gamma-ray emission from young pulsars using data taken with the H.E.S.S. imaging atmospheric Cherenkov telescope system. Data on eleven pulsars, selected ...
Modeling of gamma-ray millisecond pulsar light curves revealed by Fermi-LAT
(Thê Giói Publishers, 2009)
Fermi Large Area Telescope (LAT) has recently detected 8 gamma-ray millisecond pulsars
(MSPs), providing an unprecedented opportunity to probe the magnetospheres of these lowspin-down pulsars. We performed 3D emission ...
Gamma‐ray pulsar visibility
(AIP, 2005)
PSR J0437‐4715 is a millisecond pulsar (MSP) thought to be “pair formation starved” (having limited pair cascades due to magnetic photon absorption). Fortunately the general relativistic (GR) electrodynamical model under ...
Using an effective viscosity to account for the effect of the walls on the pressure drop through an annular packed bed
(ASME, 2009)
The question arose whether the correlation for the pressure drop prescribed for cylindrical pebble bed reactors by the Nuclear Safety Commission (KTA) of Germany could still be applied to the proposed annular configuration ...
Email security awareness: a practical assessment of employee behaviour
(Springer, 2007)
Email communication is growing as a main method for individuals
and organizations to communicate. Sadly, this is also an emerging means of
conducting crime in the cyber world, e.g. identity theft, virus attacks etc. ...
Evaluating methods to binarize historic cosmic-ray recordings
(IEEE, 2009)
Three adaptive image binarization
approaches are evaluated to find the method best suited
for the binarization of historic cosmic-ray data. The
methods are optimized by fine tuning their parameters
and they are then ...
Data acquisition system for capturing dynamic transients in a control valve
(IEEE, 2004)
This work presents the development of a data acquisition (DAQ) system to be used in conjunction with fuzzy modelling to derive a dynamic mathematical model of a control valve. Characterising the behaviour of a control valve ...
