This paper analyzes how street-level traffic data affects routing in VANETs applications. First, we offer a general review about which protocols and techniques would fit best for VANET applications. We selected five main technical aspects (Transmission, Routing, Quality of Service, Security and Location) that we consider are differential aspects of VANETs(More)
A highly accurate method for the determination of the detection efficiency of a silicon single-photon avalanche diode (Si-SPAD) is presented. This method is based on the comparison of the detected count rate of the Si-SPAD compared to the photon rate determined from a calibrated silicon diode using a modified attenuator technique, in which the total(More)
BACKGROUND Silicon single-photon avalanche diodes (Si-SPADs) are the most used devices for measuring ultra-weak optical radiant fluxes in many quantum technology fields, such as quantum optics, quantum communication, quantum computing, etc. In all these fields, the detection efficiency is the main parameter, which has to be accurately known for achieving(More)
A Marco López amb mottu del seu seixanté aniversari (To Marco López, on the occasion of his sixtieth birthday) Abstract We give explicit formulas for the subdi¤erential set of the conjugate of non necessarily convex functions de…ned on general Banach spaces. Even if such a subdi¤erential mapping takes its values in the bidual space, we show that up to a(More)
