Blazar variability -- expect the unexpected
(Sissa Medialab, 2018)
Despite significant progress in both data taking and the development of theory, blazars keep offering surprises. While many frequency bands are now covered by long-term monitoring efforts on at least a few selected sources, ...
Pulsations from the Vela pulsar down to 20 GeV with H.E.S.S. II
(Sissa Medialab, 2015)
The Vela pulsar (PSR J0835 − 4510) is the brightest persistent source in the high-energy γ-ray
sky. It is a relatively near, young and energetic rotation-powered pulsar. Vela was a key target for
the High Energy Stereoscopic ...
Constraining viewing geometries of pulsars with single-peaked γ-ray profiles using a multiwavelength approach
(SAIP, 2011)
Since the launch of the Large Area Telescope (LAT) on board the Fermi spacecraft
in June 2008, the number of observed γ-ray pulsars has increased dramatically. A large number
of these are also observed at radio frequencies. ...
Warm-start heuristics for solving the passive optical network planning problem
(Univ Stellenbosch, 2018)
The use of automated network planning systems is crucial for reducing the deployment cost and planning time of passive optical telecommunication networks. Mixed integer linear programming is well suited for the purpose of ...
