We consider the problem of comparison of two entangled states by local operations and classical communication, i. e. whether or not two entangled states are the same. We show that the optimal bound of state comparison by global measurements can also be achieved by local operations and classical communication both in the sense of conclusive comparison and inconclusive one. 03.67.-a, 03.65.Ta, 42...

Decentralized and internally diverse, the Global Justice Movement (GJM) is thought to be influenced by its use of the internet. Operating in an environment characterized by the conditions of globalization and late modernity, the movement strives to be a collective that accommodates individual difference. Focusing on the organizing process of the European Social Forum, this article examines the ...

Computer users, especially mobile ones, have developed a significant dependency on electronic communication. Enhancing the capabilities of such communication by adding an awareness of context such as location and time increases the quality and intuitiveness of the services available to the mobile user. This paper describes the design and implementation of a context-aware messaging system called...

We present a federated analysis of communication protocols which considers both security properties and timing. These are not entirely independent observations of a protocol; by using timing observations of an executing protocol it is possible to calculate encryption keys which were intended to be secret or to deduce derived information about the nature of the communication even in the presence...

Copy right I dea G roup I nc. Copy right I dea G roup I nc. A pilot exercise on the cost-benefit analysis of the use of internal email was performed at the Danwood Group. This forms part of a larger exercise to evaluate computer communication to help enhance performance throughout the organisation. The chapter has resulted in the creation of an internal email costing process showing when it sta...
