In this work we present a calibration-free system for locating wireless local area network devices, based on the radio frequency characteristics of such networks. Calibration proc...
Independent from specific application domains, similar requirements can be identified regarding information needs during daily work. For coping with generality on the one hand an...
Abstract. Recently we showed how to justify a Dolev-Yao type model of cryptography as used in virtually all automated protocol provers under active attacks and in arbitrary protoco...
