Abstract: There are provided an apparatus and method for retransmitting data according to a radio link protocol in a mobile communication system. In the method of requesting frame retransmission, a receiver stores the sequence numbers of a plurality of RLP (Radio Link Protocol) frames that are not received from a transmitter and transmits a retransmission request frame including fields that indicate the sequence numbers. Then, the transmitter sequentially transmits the requested RLP frames in the order of the sequence numbers to the receiver. The receiver compares the stored sequence numbers with the sequence numbers of received RLP  frames and if it receiver fails to receive one of the requested RLP frames, the receiver requests retransmission of the lost RLP frame upon receipt of an RLP frame of a higher sequence number than the sequence number of the lost RLP frame.

Abstract: Une méthode d'appariement de formes servant à la reconnaissance d'objets dans une image, utilise un modèle défini par une série d'une ou de plusieurs primitives modèles représentatives de structures à grande échelle d'un archétype. L'image est analysée pour dériver au moins une primitive cible représentative d'une structure à grande échelle de l'image. Une base est dérivée à partir d'au moins une des primitives cibles, et chaque primitive cible représentée comme invariante dans la base dérivée. Pour chaque primitive cible, toutes les primitives modèles qui correspondent au moins partiellement à la primitive cible sont identifiées. Chaque primitive modèle identifiée est ensuite traitée pour le calcul d'un chiffre de mérite indicatif d'un degré de correspondance entre la primitive cible et la primitive modèle. Dans quelques réalisations, le chiffre de mérite est une projection orthogonale entre les primitives cible et modèle, qui est accumulé pour chaque base de modèle.

Abstract: A concept identification system useful in reducing and/or representing text content of an electronic document and in highlighting the content of the document. A concept knowledge base comprises a plurality of concepts and each concept comprises one or more subconcepts linked to each other and to the concept on a hierarchical basis. One or more of the subconcepts may be linked to one or more subconcepts of another concept. A concept matching module matches text of the document to subconcepts of the concept knowledge base and assesses any links between the matched subconcepts and other concepts and/or subconcepts of the concept knowledge base. From this a determination is made of whether the document relates to a concept of the knowledge base. With an identification of such concept a document representation generator may produce a precis of the document based on a template associated with such concept. For highlighting of a document a highlighter module determines key content of the input document and an interface integrates the concept identification system and the highlighter module. An output module produces an output highlight document from the key content.
