We report the near-IR detection of a prominent CIV absorption in the rest-frame UV spectrum of the most distant known QSO, SDSS J104433.04−012502.2, at z = 5.80. This QSO was recently observed with XMM-Newton and it was found to be notably X-ray weak. The equivalent width of the CIV absorption feature (∼10Å) strongly supports the idea that the X-ray faintness of this QSO is due to heavy absorpt...

The goal of the ADEQUATe project is to assess and improve quality of the (tabular) open data being published at two Austrian open data portals – https://www.data.gv.at and https://www.opendataportal.at. The goal of the quality improvement technique described in this paper is to semantically interpret such tabular data and publish them as Linked Data; this basically means to (1) classify columns...

Columns are the key load-bearing elements in frame structures and exterior columns are probably the most vulnerable structural components to terrorist attacks. Column failure is normally the primary cause of progressive failure in frame structures. A high-fidelity physicsbased computer program, LS-DYNA was utilized in this study to provide numerical simulations of the dynamic responses and resi...

Abstract: Polyurethane-steel sandwich structure, which creatively uses the polyurethane-steel sandwich composite as a structural material, is proposed to strengthen the impact resistance of buildings under debris flow. The impact resistance of polyurethane-steel sandwich structure under debris flow is investigated by a series of impact loading tests, compared with that of traditional steel fram...

Recent advances in uncooled detector technology now offer the possibility of using relatively inexpensive thermal (7 to 14 μm) imaging devices as tools for studying and quantifying the behaviour of hazardous gases and particulates in atmospheric plumes. An experimental fast-sampling (60 Hz) ground-based uncooled thermal imager (Cyclops), operating with four spectral channels at central waveleng...
