The increase in the amount of data on the Internet has led to the development of a new generation of applications based on selective information dissemination where, data is distributed only to interested clients. Such applications require a new middleware architecture that can efficiently match user interests with available information. Middleware that can satisfy this requirement include even...

Knowing the information dissemination mechanisms of different media and having an efficient information dissemination plan for disaster pre-warning plays a very important role in reducing losses and ensuring the safety of human beings. In this paper we established models of information dissemination for six typical information media, including short message service (SMS), microblogs, news porta...

Broadcasting and gossiping are known to be NP hard problems This paper deals with approximation algorithms for such problems We consider both round complexity and step complexity in the telephone model After an overview of previously derived approximation algorithms we present new strategies for broadcasting and gossiping in any graphs Broadcasting strategies are based on the construction of ed...

Roadway lane marking detection is essential for lane departure warning and enabling autonomous vehicles. Instead of using lane markings only as visual aids to indicate the boundary of two adjacent lanes, it is possible to also include digital information in the lane to provide geographically specific information. This enables in-tunnel navigation data, location-specific service advertisement, c...

Peer-to-Peer computing paradigm may provide a solution to the retrieval problem in an ever burgeoning volume of online and digital information. While research has focused on the means of collaboration as a tool for query routing, we feel that there is a disconnect in the way P2P networks are handled and the expectations of performance in the real world. In the proposed work, we discuss the need...

This paper focus on device aware context delivery with middleware based support for heterogeneous client devices. Data networks are increased tremendously to support heterogeneous devices. There are myriad of new portable computing devices that each have different capabilities with regard to communication platform, communication protocol, computing power, display capabilities etc. Middleware ba...

Social networks can have asymmetric relationships. In the online social network Twitter, a follower receives tweets from a followed person but the followed person is not obliged to subscribe to the channel of the follower. Thus, it is natural to consider the dissemination of information in directed networks. In this work we use the mean-field approach to derive differential equations that descr...

This paper addresses recent progress in speaker-independent, large vocabulary, continuous speech recognition, which has opened up a wide range of near and mid-term applications. One rapidly expanding application area is the processing of broadcast audio for information access. At LIMSI, broadcast news transcription systems have been developed for English, French, German, Mandarin and Portuguese...

Existing reliable transport protocols for periodic information dissemination ignore application semantics while attempting to be 100% reliable. \Application Level Framing" (ALF) suggests that taking application semantics into account when designing transport protocols can result in performance that is highly optimized for the network. We apply this principle in designing a policy-based TUNAble ...
