Résumé. Ce papier présente notre méthode de conception de bases de données multidimensionnelles (BDM) contraintes. Nous proposons une méthode mixte basée sur une démarche descendante et une démarche ascendante. La démarche descendante est composée de trois étapes: la collecte des besoins des décideurs, la spécification et la formalisation de ces besoins suivant un modèle multidimensionnel en co...
Here, we report a draft genome sequence of Saccharomyces cerevisiae strain Kagoshima no. 2, which is used for brewing shōchū, a traditional distilled spirit in Japan. The genome data will facilitate an understanding of the evolutional traits and genetic background related to the characteristic features of strain Kagoshima no. 2.
In this paper, we present a novel foreground extraction method that automatically identifies image regions corresponding to a common space region seen from multiple cameras. We assume that background regions present some color coherence in each image and we exploit the spatial consistency constraint that several image projections of the same space region must satisfy. Integrating both color and...
The lectures describe several cosmological effects produced by neutrinos. Upper and lower cosmological limits on neutrino mass are derived. The role that neutrinos may play in formation of large scale structure of the universe is described and neutrino mass limits are presented. Effects of neutrinos on cosmological background radiation and on big bang nucleosynthesis are discussed. Limits on th...
In a recent paper [1] it has been suggested that the velocity of light and the expansion of the universe are two aspects of one single concept connecting space and time in the expanding universe. It has then be shown that solving Friedmann's equations with that interpretation (and keeping c = constant) can explain number of unnatural features of the standard cosmology (for example: the flatness...
BACKGROUND We have been observing that a significant proportion of our patients, especially females, have certain pigmentary demarcation lines (PDL) over the face. However, systematic studies of the subject are lacking. AIMS We categorized the different clinical patterns of facial PDLs in the Indian subpopulation and assessed their prevalence in this study. METHODS About 4000 consecutive pa...
Automatic segmentation of foreground from background in video sequences has attracted lots of attention in computer vision. Two different implementations have been completed during the summer. The first one is known as “background subtraction”. The foreground is segmented from the background by directly subtracting a mean background image B from each frame, and retaining those parts of the fram...
By construction, a video is a series of ordered frames, whose order is defined at the time of the acquisition process. Background subtraction methods then take this input video and produce a series of segmentation maps expressed in terms of foreground objects and scene background. To our knowledge, this natural ordering of frames has never been questioned or challenged. In this paper, we propos...
The early universe according to the big bang and the grand unified theories is discussed. The shortcomings of big bang are summarized together with their resolution by inflationary cosmology. Inflation, the subsequent oscillation and decay of the inflaton, and the resulting ‘reheating’ of the universe are studied. The density perturbations produced by inflation and the temperature fluctuations ...
