Quality of Multimedia Experience: Past, Present and Future
Graph Chatbot
Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We develop a joint playout buffer and Forward Error Correction (FEC) adjustment scheme for Internet Telephony that incorporates the impact of end-to-end delay on the perceived audio quality. We show that it provides a better quality than the adjustment sch ...
Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...
We survey recent advances in theories and models for Internet Quality of Service (QoS). We start with the theory of network calculus, which lays the foundation for support of deterministic performance guarantees in networks, and illustrate its applications ...
Nature abounds in examples of cellular systems. From ant colonies to cellular tissues, from molecular systems to the human brain, cellularity seems to be the way Nature operates. The brain, surely one of the most complex objects to be found on earth, is th ...
The metrics used, thus far, to assess bioartificial organ function are shown to be subjective and requiring validation. Therefore, four categories of correlations are proposed based on, respectively, device, in vitro and in vivo evaluations, and clinical f ...
Communication networks are expected to offer a wide range of services to an increasingly large number of users, with a diverse range of quality of service. This calls for efficient control and management of these networks. In this paper, we address the pro ...

In order to define a real-world model problem for research work in the area of predictable assembly of certifiable software components, this paper introduces the substation automation domain, as a representative for the wide spectrum of data acquisition an ...

Any innovative design of a chem. or biol. reactor has to consider the dynamics of the primary phys. and chem. steps involved in the overall process. For homogeneous highly viscous systems the mixing time is of crucial importance for the product quality. In ...
It was in the first half of the 18th century when life sciences started to flourish in the independent republic of Geneva. However, it is difficult to identify a genuine school of developmental biologists during that era. Nevertheless, several prominent sc ...
