Avec les lancements réussis des missions ESA Soil Moisture and Ocean Salinity (SMOS) et NASA Aquarius/SAC-D, la salinité de surface des océans peut maintenant être déduite. De plus, les produits de couleur de l'eau, tels que les mesures d'absorption et d'atténuation de la lumière et de concentration en chlorophylle, peuvent être utilisés comme traceurs de la salinité. Les signatures des panaches des grands fleuves tropicaux tels que l'Amazone et l'Orénoque peuvent être étudiées en détail grâce à ces nouvelles méthodes.

Abstract:
Coastal and estuarine ecosystems are heavily influenced through floating debris pollution. This often leads to low-quality coastal water and a negative impact on ecosystem health. This thesis has shown that the use of Lagrangian coherent structures (LCS) can predict hotspots of debris accumulation, repelling and upwelling circulation. Such hotspots have a strong socio-economic importance for visual amenity and efficient debris clean-up operations. LCS is a technique which is highly robust to hydrodynamic model uncertainties. This approach thus provides a useful tool for effective clean-up mana

Abstract:
<p>The semiconductor laser is the linchpin of optical communication and is now also penetrating a wide spectrum of new applications such as biomedical sensing, coherent communication, metrology, and time keeping. These require a higher degree of temporal coherence than is available from the present generation. Recently, it has been proposed and shown that heterogeneously integrated lasers on silicon and InGaAsP can be used to design high coherence single mode lasers with a much narrower linewidth than their all InGaAsP counterparts. Unfortunately, these lasers suffer from large thermal impedan

Abstract:
This thesis has two major objectives. The first objective is to investigate the seasonal and diurnal variations in occurrence of HF coherent echoes. We assess F-region echo occurrence rates for the PolarDARN HF radars at Inuvik (INV) and Rankin Inlet (RKN) and the auroral zone SuperDARN radars at Saskatoon (SAS) and Prince George (PGR) for the period of 2007-2010. We show that the INV and RKN PolarDARN radars show comparable rates of echo occurrence all the time and they detect 1.5-2.5 times more echoes through ½-hop propagation mode (MLATs=80°-85°) than the SAS and PGR SuperDARN radars throug

Abstract:
Enhancing the performance of mixing and fluid entrainment by excitation of quasi-steady jets has been a subject of research for more than three decades. During the 1980s a special emphasis was placed on mechanically oscillating planar jets and the possibility to augment thrust of V/STOL aircraft. However, during this time, little attention was paid to the classification of flow regimes, the development of coherent structures or the existence of different regions in the flow within the jet near field. For the present study, a large aspect ratio nozzle was oscillated in the direction transverse

L’articulation de l’urbanisme et des transports s’est imposée comme une question centrale dans la sphère des planifications à incidences spatiales. Le développement durable comme concept cadre a mis en relief cette problématique dont les enjeux décident de la qualité de vie urbaine au quotidien. Les objectifs de cette articulation coïncident avec la maitrise de l’étalement urbain et le report modale de la voiture vers le transport collectif. Pour atteindre ces objectifs, la cohérence des planifications respectives et de leur mise en œuvre doit être assurée. Ce qui appelle à remplir des conditi
