We propose a new method for content-based image retrieval which exploits the similarity measure and indexing structure of totally randomized tree ensembles induced from a set of subwindows randomly extracted from a sample of images. We also present the possibility of updating the model as new images come in, and the capability of comparing new images using a model previously constructed from a different set of images. The approach is quantitatively evaluated on various types of images with state-of-the-art results despite its conceptual simplicity and computational efficiency [less ▲]

We studied the within-population genetic structure and the clonality extent of Viola calaminaria, a rare endemic species of calamine soils, by means of RAPD markers in two populations (one recent and one ancient) with expected harsh and heterogeneous heavy-metal stress. At a very local scale (0.2 3 m), clonal propagation was detected in both populations, but the levels of clonal diversity were high (number of genets/number of ramets sampled ¼ 0.9 [recent] and 0.76 [ancient]) and the maximal observed extension of the clones was 0.4 m. This indicated that clonality is not, for the species, an important mode of propagation and that clonal growth cannot be interpreted as a strategy for propagating or perpetuating adapted genotypes under harsh ecological constraints. Spatial autocorrelations revealed a significant (P , 0.001) negative value of correlogram slope in the two populations even when a single individual per clone was considered (i.e., analysis at the genet level). We conclude that spatial genetic structure at a very local scale reflects limited gene flow due to restricted seed dispersal rather than variation in clonal pattern in response to environmental heterogeneity. At a larger scale (2–30 m), spatial autocorrelations revealed a positive (P , < 0.001) correlation at , 3 m and a random pattern at larger distances for the two populations. This suggested a patchy distribution of the genetically linked individuals associated with a disrupted pattern at a longer distance probably due to gene flow by pollen dispersal and a seed bank effect. The implications for the conservation of V. calaminaria are discussed. [less ▲]

The bi-axial experimental equipment [Flores, P., Rondia, E., Habraken, A.M., 2005a. Development of an experimental equipment for the identification of constitutive laws (Special Issue). International Journal of Forming Processes] developed by Flores enables to perform Bauschinger shear tests and successive or simultaneous simple shear tests and plane strain tests. Flores investigates the material behavior with the help of classical tensile tests and the ones performed in his bi-axial machine in order to identify the yield locus and the hardening model. With tests performed on one steel grade, the methods applied to identify classical yield surfaces such as [Hill, R., 1948. A theory of the yielding and plastic flow of anisotropic materials. Proceedings of the Royal Society of London A 193, 281–297; Hosford, W.F., 1979. On yield loci of anisotropic cubic metals. In: Proceedings of the 7th North American Metalworking Conf. (NMRC), SME, Dearborn, MI, pp. 191–197] ones as well as isotropic Swift type hardening, kinematic Armstrong–Frederick or Teodosiu and Hu hardening models are explained. Comparison with the Taylor–Bishop–Hill yield locus is also provided. The effect of both yield locus and hardening model choices is presented for two applications: plane strain tensile test and Single Point Incremental Forming (SPIF). [less ▲]

Les résultats obtenus dans le cadre du suivi DCE 2006 du phytoplancton des eaux côtières corses ont permis: − de tester et de valider une stratégie d’échantillonnage originale adaptée aux réseaux de surveillance et aux spécificités régionales; − de caractériser globalement les communautés phytoplanctoniques de 6 masses d’eau côtières ne présentant pas de risque NABE à l’horizon 2015 (Calvi, Cargèse, Pianottoli, Est Cap Corse, Sud Bastia et Sant’Amanza); - de démontrer le très bon état des masses d’eaux échantillonnées pour l’indicateur Phytoplancton; - d’émettre des recommandations visant à optimiser l’effort d’échantillonnage et la validité des résultats. La stratégie d’échantillonnage testée et validée propose de réaliser deux suivis « haute fréquence » au niveau des sites de référence de Calvi et de la station « Sud Bastia ». L’échantillonnage doit être réalisé en subsurface toute l’année, une fois par semaine de janvier à juin et une fois par quinzaine de juillet à décembre. Les autres masses d’eau sont échantillonnées une fois par mois, de janvier à décembre. Les résultats 2006 mettent en évidence les caractéristiques communes des communautés phytoplanctoniques des masses d’eau de Calvi, Cargèse et Pianottoli et des masses d’eau Est Cap Corse, Sud Bastia et Sant’Amanza. Ceci suggère que les suivis réalisés dans le cadre des contrôles de surveillance pourraient se limiter aux observations « haute fréquence » réalisées à Calvi et à la station « Sud Bastia ». [less ▲]

Purpose - To develop a sub-domain perturbation technique for efficiently modeling moving systems in magnetodynamics with a magnetic field h-conform finite element (FE) formulation. Design/methodology/approach - A reference problem is first solved in a global mesh excluding some moving regions and thus avoiding the inclusion of their meshes. Its solution gives the sources for a sequence of perturbation problems with the supplementary moving magnetic and conductive regions. Each of these sub-problems requires an appropriate proper volume mesh of the associated moving region and its surrounding region, with no need of interconnection. The solutions are transferred from one problem to the other through projections of source fields between meshes. Findings - The consideration of sub-problems and associated sources, in a sequence of perturbation problems, leads to a significant speed-up of the repetitive solutions in analyses of moving systems. A free movement in any direction can be considered with no need of remeshing. Originality/value - When working with the perturbation fields, the volume sources can be limited to the moving regions, what allows for homogeneous perturbation boundary conditions and reduces the computational efforts for projecting and evaluating the sources. The curl-conformity of the unknown magnetic field is preserved during the whole process thanks to the use of edge FEs for both the magnetic field and the intermediate source quantities. The sub-problem approach also gives an easy way to directly express the time derivatives in moving frames. [less ▲]

Didelphys uterus with imperforated obstructed hemivagina is a rare condition. Most often, it is diagnosed a few months after the menarche. Hematocolpos, hematometria and sometimes hematosalpinx are responsible for pelvic pain and dysmenorrhea. Symptoms can be delayed when a fistulisation from the hematocolpos to permeable contralateral vagina is present. Sometimes, diagnosis is not made before adulthood during an infection of the hematocolpos. Useful additional exams include pelvic ultrasound and, in some cases, MRI, which is the best exam to precisely describe the type of malformation. An ipsilateral agenesia of the kidney is always associated. Hysterography can usually demonstrate the fistulous courses. Treatment consists in a large resection of the vaginal septum in order to allow a permanent drainage of the hemiuterus. A laparoscopy should be performed to check for the presence of associated tubal or pelvic damage. [less ▲]
