International audience; Cette communication porte sur différentes proximités et médiations à travers deux romans francophones, "Les Nuits de Strasbourg" (1997) d'Assia Djebar et "Le Village de l'Allemand ou le journal des frères Schiller" (2008) de Boualem Sansal. La première partie traite de la posture (Meizoz) ou de l'image de ces auteurs dans le champ littéraire (Bourdieu, Casanova), telle que médiée par ces ouvrages. Ensuite, nous nous intéresserons à la mémoire multidirectionnelle (Rothberg) dans ces romans car l'intertextualité et l'intermédialité médient des proximités mémorielles et interculturelles. Enfin, la lecture sera considérée comme une potentielle médiation du réel.
Directionlets: Anisotropic Multidirectional representation with separable filtering
2006
In spite of the success of the standard wavelet transform (WT) in image processing in recent years, the efficiency of its representation is limited by the spatial isotropy of its basis functions built in the horizontal and vertical directions. One-dimensional (1-D) discontinuities in images (edges and contours) that are very important elements in visual perception, intersect too many wavelet basis functions and lead to a nonsparse representation. To efficiently capture these anisotropic geometrical structures characterized by many more than the horizontal and vertical directions, a more complex multidirectional (M-DIR) and anisotropic transform is required. We present a new lattice-based pe…
Directional Control Mechanisms in Multidirectional Step Initiating Tasks.
2020
Typical anticipatory postural adjustments (APAs) in forward gait or step initiation tasks to prepare for possible disturbances caused by prime voluntary movements and to accelerate the body forward have been previously reported. However, it is not clear how wide the variations in step directions are differentiated and controlled in non-forward step initiation tasks during the APA phase. The main goal of this study is to explain the directional control mechanisms by investigating the APA of step initiation tasks in forward, diagonal, lateral, and posterior directions. The center of pressure (COP) trajectories and related muscle (soleus, tibialis anterior, and gluteus medius of both lower lim…
Möglichkeiten der CT-Arthrographie in der Diagnostik von Schulterinstabilitäten
1990
In the course of a prospective study, CT arthrography was carried out on 40 patients with shoulder instability. In 35 of these patients a lesion of the capsule and labrum was demonstrated, indicating glenohumeral instability; in three patients this was shown primarily by CT arthrography. In three patients, multidirectional instability was demonstrated. In four patients there was an isolated lesion of the labrum, whereas in one patient all the findings were normal. Compared with the capsulo-labral lesions, bone changes involving the head of the humerus and the glenoid were of lesser importance, although their severity affected the choice of operative treatment in four patients. Fifteen of th…
