Presence sensors, which are widely deployed in modern buildings, attempt to regulate lighting to the presence of people in indoor spaces. Though, much more in terms of comfort and energy efficiency can be achieved if more detaile...

This document defines an XML format for the representation of civic location. This format is designed for use with Presence Information Data Format Location Object (PIDF-LO) documents and replaces the civic location format in RFC 4119. The format is based on the civic address definition in PIDF-LO, but adds several new elements based on the civic types defined for Dynamic Host Configuration Pro...

Developer email messages were col...

In this paper, we compare the impact of monophonic, stereophonic, and binaural human speech recordings in terms of their ability to induce the feeling of presence and influence the understanding of the emotional state the speakers were in. These factors are generally important in entertainment applications, for example when conversing with a non-player character or in mediated synchronous human...

Our approach presents some interesting novelties with respect to the existing ones. First of all, it operates on a Social Internetworking context and not on a single social network. Moreover, it considers not only explicit relationships among users but a...
