2014 The electron spin-lattice relaxation time T1 of V4+ in amorphous V2O5 has been measured in the X-band between 1.4 K and 100 K : T1-1 = 39 T2 $$ ~056/T x dx sinh x We explain this behaviour using a process requiring one two-level system (T.L.S.) modulating the crystal field, and one phonon. The characteristic temperature 56 K must be associated not with the maximum energy of the T.L.S. but ...

The few known γ-ray binary systems are all associated with variable radio and Xray emission. The TeV source HESS J0632+057, apparently associated with the Be star MWC148, is plausibly a new member of this class. Following the identification of a variable X-ray counterpart to the TeV source we conducted GMRT and VLA observations in June-September 2008 to search for the radio counterpart of this ...

This paper deals with Exploratory Procedures for Computer Vision. The assumptions are that we have a mobile camera system with controllable focus, close/open aperture, and ability of recording its position, orientation and movement. Furthermore we assume an unknown and unstructured environment. For our analysis we consider two types of illumination sources: the point source and the extended sky...
