Deep convolutional neural networks (CNNs) have had a major impact in most areas of image understanding, including object category detection. In object detection, methods such as R-CNN have obtained excellent results by integrating CNNs with region proposal generation algorithms such as selective search. In this paper, we investigate the role of proposal generation in CNN-based detectors in orde...

La lagune Ebrié, plan d’eau vitale pour l’économie de la Côte d’ Ivoire, subit des pressions naturelles et anthropiques qui ont conséquences néfastes sur sa faune aquatique. En effet, elles rejettent dans ce hydrosystème d’importantes quantités polluants organiques, entrainant son eutrophisation. Une meilleure connaissance distribution ces Ebrié pourrait conduire à préservation durable. Cette é...

Dans le programme de reconstitution l’histoire des estuaires et lagunes du Sénégal l’inventaire la microflore à diatomées Séné-Gambie, une carotte sondage 400 cm long a été réalisée Ndangane Babou sur un bras l’estuaire Saloum (14°07?53.86? N/16°17?40.08? W) 95 km l’embouchure. L’analyse comparée lithologie montré corrélation significative entre fraction pélitique, l’abondance absolue leur dive...

It is a matter of strategic independence for many countries to urgently find processes that take into account environmental and economic issues when recycling critical metals. Liquid–liquid (L/L) extraction promising method recovering rare-earth elements from electrical electronic waste. However, an optimized process on industrial scale has not yet been established. One the main reasons lack fu...

Accumulating evidence suggests that wheezing illnesses have at least part of their origin in the infantile period, wherein septal restructuring and alveolar formation ensue. Therefore, throughout infancy, genetic and environmental factors could affect bronchial development and future airway function. On this basis, we hypothesised that differential growth velocity, within the first 6 months of ...

Genetic polymorphism at the loci encoding the enzymes phosphoglucose isomerase, leucine aminopeptidase and phosphoglucomutase was investigated in Irish Mytilus populations. Allele frequencies and heterozygote proportions indicated that populations on exposed Atlantic coasts differed from those on sheltered Atlantic coasts, and from Irish Sea mussels. When compared with data on M. edulis collect...

A series of five locks form a transportation bottleneck in the upper Mississippi River navigation system. With optimizing models, statistical modeling and computer simulation, the authors explore the effects of alternative scheduling regimes and infrastructure changes to improve performance of an inland waterway transportation system. In this paper, the authors show the value of triangulating a...

A reduction in Ocean. The species is taken in directed fishing mortality of approximately 60% recreational and artisa...
