Mobile awareness applications connect you with the activities of friends, colleagues, and communication partners. The development of awareness applications for mobile devices is a top priority for HCI researchers. In discovering boundaries for mobile awareness systems, it is important to consider how these devices will be used. Factors relevant to design include boundaries drawn by technical, f...

Systems must provide for mobile applications to be aware of the context in which they are being used. This is necessary to permit adaptation to heterogeneity of hosts and networks and variations in the user’s environment, and so enable applications to be effective in a wide range of devices and situations. While we acknowledge that deterministic QoS management may be unrealistic in these circum...

XQuery is a DBPL for querying XML databases. The semantics of XQuery is context sensitive and requires preservation of document order. In this paper, we propose, as far as we are aware, the first XQuery fusion that can deal with both the document order and the context of XQuery expressions. More specifically, we carefully design a context representation of XQuery expressions based on the Dewey ...

S. Adler R. Cochrane J. F. Morar A. Spector The Extensible Markup Language (XML) is an open standard for creating domainand industry-specific markup vocabularies. XML has become the predominant mechanism for electronic data interchange between information systems and can be described as a universally applicable, durable ‘‘Code of Integration.’’ As we celebrate its tenth anniversary, it is appro...

The events of 9/11, subsequent anthrax incidents, as well as attacks in London, Spain and elsewhere, have brought increasing attention to the probability of NATO nations becoming a target of a terrorist threat. While telecommunications infrastructures may not be a specific target for attack, the consequences of a Chemical, Biological, Radiological, Nuclear, Explosive (CBRNE) incident on such Cr...

Electronics and telecommunications are rapidly changing and are having significant impacts on social and economic activity, with major implications for transportation. Location of businesses and households may be altered as telecommunications options improve. Already, there is evidence that businesses have become less dependent on proximate locations as electronic links have become more effecti...
