The availability of many independent services on an open network opens the opportunity of composing individual instances to achieve complex functionality. Most often there are several possible compositions to achieve the same high- level functionality; the advantage of choosing one composition instead of another one may lie in the different quality of the composition, e.g., one might be cheaper, faster,...
In this paper, we investigate new approaches to improve speech activity detection, speaker segmentation and speaker clustering. The main idea behind them is to deal with the problem of speaker diarization for meetings where error rates are relatively high. In opposition to existing methods, a new iterative scheme is proposed considering those three tasks as only one problem. New bidirectional source...
Creating a service-oriented architecture requires the identification of services to be composed together in order to solve a given need. Currently, software engineers perform this design task by hand by identifying services and how to compose them. In this paper, we propose RuGCo a system to automatically compose Web services coming from a static large repository, according to a domain ontology expressed...
We evaluate in this paper how the hypothesis that basic video and audio features present homogeneous values during programs can be exploited by a GLR-BIC segmentation algorithm to identify programs in days of television contents. The homogeneity criterion is evaluated by the ability to describe this feature values with a Gaussian law. On the base of results obtained from rough audio and video features,...
In the audiovisual indexing context, we propose and experiment a method that, from an audio speaker segmentation and a video costume segmentation made on an audiovisual document, makes an automatic association between each voice and the images containing the corresponding visual person. This association can be used as a preprocessing step for existing applications like person identification systems...
Nous rapportons deux observations de varicelle congénitale. La première comportait une aplasie cutanée ; la seconde associait des cicatrices, une atrophie paralytique d’un hémicorps, un syndrome d’Horner et des calcifications hépatiques, avec un pronostic fonctionnel réservé. Après une revue récente de la littérature, nous soulignons l’intérêt de la vaccination chez les femmes en âge de procréer,...
In a recent study, we observed that the 24-hour leucine oxidation measured when three equal meals providing a generous intake of leucine (~90 mg . kg -1 . d -1 ) are eaten during the day is 16% lower (P < .01) than that for the same diet given as 10 hourly, equal meals. We hypothesized that the pattern of meal intake at a lower level of dietary leucine would affect the...
