The media and TV world faces new challenges such as the introduction of digital and interactive TV. In order to cope with the complexity of these new services, a well-structured back office is of prime importance. Today, efficient management of content is hampered by the proprietary formats used in the different software applications that have been developed by various vendors. Moreover, the la...

These paper introduces a reservation subframe protocol for multimedia services in a 3rd generation mobile telecommunication system. The Packet Reservation Multiple Access (PRMA) protocol is modified to achieve more efficient bandwidth management. Simulation results show that the resulting multiple access multimedia system can serve a large number of users with low probability of packet loss, en...

We estimate the demand for local news service described by the offerings from newspapers, radio, television, the Internet, and Smartphone. The results show that the representative consumer values diversity in the reporting of news, more coverage of multicultural issues, and more information on community news. About two-thirds of consumers have a distaste for advertising, which likely reflects t...

We examine how product and pricing decisions of retail gasoline stations depend on local market demographics and the degree of competitive intensity in the market. We are able to shed light on the observed empirical phenomenon that proximate gasoline stations price very similarly in some markets, but very differently in other markets. Our analysis of product design and price competition between...

The aims of this study are twofold. We first seek to validate a previous study conducted on one speaker. It identified lower face visible articulatory correlates of contrastive focus in French for real (nonreiterant) speech. We thus conducted the same study for another speaker. Our second goal was to enlarge the set of cues measured to other facial movements. To do so we used a complementary me...

This paper studies microlocal regularity properties of the distributions f on a strongly noncharacteristic submanifold E of a hypoanalytic manifold M that arise as the boundary values of solutions on wedges in M with edge E. The hypo-analytic wave-front set of f in the sense of Baouendi-Chang-Treves is constrained as a consequence of the fact that f extends as a solution to a wedge.

Fleet assignment models are used by many airlines to assign aircraft to flights in a schedule to maximize profit [Abara 1986, Hane et al 1995]. A major airline reported that the use of the fleet assignment model increased annual profits by more than USD100 million [www.informs.org, 2002] a year over three years. The results of fleet assignment models affect subsequent planning, marketing and op...
