The French-Italian interferometric gravitational wave detector VIRGO is currently being commissioned. Its principal instrument is a Michelson interferometer with 3 km long optical cavities in the arms and a power-recycling mirror. This paper gives an overview of the present status of the system. We report on the presently attained sensitivity and the(More)
Aims. The detection and measurement of gravitational-waves from coalescing neutron-star binary systems is an important science goal for ground-based gravitational-wave detectors. In addition to emitting gravitational-waves at frequencies that span the most sensitive bands of the LIGO and Virgo detectors, these sources are also amongst the most likely to(More)
VIRGO, a French-Italian collaboration located in Cascina (Pisa, Italy) aiming at the detection of gravitational waves, is a ground based power recycled Michelson interferometer, which arms are 3-km-long Fabry-Perot suspended cavities. The VIRGO first scientific data taking has started in mid may 2007 in coincidence with the corresponding American detectors.(More)

A B S T R A C T Wireless sensors networks are technologically mature, however, the requirements in terms of energy, preventing them from wide spreading. Energy-awareness in wireless sensors networks has been principally explored in networking, with ad-hoc routing mechanisms and protocols. A join effort is however needed from different level, from the(More)
Second-generation interferometric gravitational-wave detectors will operate at temperatures noticeably above room temperature. Study was done to determine what effect elevated temperatures would have on the Q and coating thermal noise of the detector mirrors. Results show that increased temperature increases loss angle in a manner that is more significant(More)
