Le Complexe Membranaire Superficiel Et Son Evolution Lors De L'elaboration Des Individus-fils Chez Toxoplasma Gondii

The parasitic protozoan Toxoplasma gondii has been examined with the electron microscope in order to study the fine structure and the formation of the membranes surrounding the cell. The study of the ultrastructure of the membranes covering the parasite shows the existence of a three-membraned complex. Only the outer membrane is considered to be the plasma membrane; the two membranes below it f...

Retweeter ou ne pas retweeter : Le dilemme des portails de diffusion d'information temps-réel

The study of contextual features has been widely discussed in Information Retrieval (IR), but concrete applications on real data streams are not common. In this paper, we aim at doing retweet recommandation. Considering a user interest, we introduce a model to perform real-time online filtering of the Twitter stream using several contextual features. The model separates content and contextual a...

Reconnaissance des formes par méthodes à noyau dans le domaine temps-fréquence

During the last decade, many important advances have been made in the field of pattern recognition with the theory of reproducing kernels. This unified view has led to new algorithms with improved performance and lower computational complexity. In this paper, we show that some specific reproducing kernels allow these algorithms to operate on time-frequency representations. This link offers new ...
