Et Aveugles En Traitement Du Signal Et Des Images

We consider the problem of subspace estimation in aBayesian setting. Since we are operating in the Grassmann man-ifold, the usual approach which consists of minimizing the meansquare error (MSE) between the true subspace and its estimatemay not be adequate as the MSE is not the natural metric in theGrassmann manifold , i.e., the set of -dimensional subspacesin . As an al...

Ordonnancement d'entités pour la rencontre du web des documents et du web des données

The advances of the Linked Open Data (LOD) initiative are giving rise to a more structured web of data. A few datasets act as hubs (e.g., DBpedia) connecting many other datasets. They also make possible new web services for entity detection inside plain text (e.g., DBpedia Spotlight), thus allowing for new applications that will benefit from a combination of the web of documents and the web of ...

Réactions redox du plutonium et de l'antimoine avec des minéraux de fers en milieux anoxique

Redox reactions of Sb(V) and Sb(III) with mackinawite (FeS) and of aqueous Pu(III) and Pu(V) with various Fe(II)‐bearing minerals and Fe(III)‐oxides have been investigated under anoxic conditions. X‐ ray absorption spectroscopy was used to analyze oxidation state and local coordination environment of Sb and Pu associated with the solid phase. After reaction with mackinawite, chukanovite and...
