Motivated by the revolution in the media industry brought by recent developments in video access and sharing, this paper investigates the future of internet video. We present new web standards such as HTML5, promising unified, simple and platform independent access to video files and streams, as well as novel techniques for adaptive video coding. We also(More)
The evolution of the Internet is being leaded by two main threads, one driven by industry through the evolution of networking infrastructures and the other driven by producers of content either in a professional or non professional way. Moreover, due to the explosion of the World Wide Web (which has started as a document repository) and its successful(More)
The rapid growth of social media and the ubiquitous availability of audiovisual content have transformed virtually every aspect of our personal and professional lives. In Internet-based multimedia applications users with their activity (including social life) are both the source of data and the consumers of the applications, hence being involved in the(More)
Recently, methyl formate, glycolaldehyde, and acetic acid have been detected in the Interstellar Medium, ISM. The rate constants, α(e), for dissociative electron-ion recombination of protonated gycolaldehyde, (HOCH(2)CHO)H(+), and protonated methyl formate, (HCOOCH(3))H(+), have been determined at 300 K in a variable temperature flowing afterglow using a(More)
Following the arrival of Cassini at Titan in 2004, the Titan atmosphere has been shown to contain large complex polycyclic-aromatic hydrocarbons. Since Cassini has provided a great deal of data, there exists a need for kinetic rate data to help with modeling this atmosphere. One type of kinetic data needed is electron-ion dissociative recombination (e-IDR)(More)
Laboratory data have a dual and critical role in interpreting information obtained from the Cassini spacecraft in its passes through the Titan ionosphere. Firstly, in situ mass spectra are obtained by Cassini and their conversion into atmospheric molecular composition requires chemical modeling to create agreement between the observed mass spectra and those(More)
