The current worldwide consumption of bitumen is about 100 million tons. A remarkable combination of properties (adhesion, impermeability to water, specific thermo-rheological behavior) makes it a key material in road construction. Today's bitumen is mostly obtained from petroleum refining, so bioabased alternatives have to be explored for the futur...
Worldwide, about 100 million tons of bitumen are used per year. Mainly from petroleum refining, although bitumen can exist in natural form, this material is used because of its unique combination of properties: adhesion, impermeability to water and specific thermo rheological behaviour. Due to petroleum dependency, the future of petroleum-based bit...
This paper presents a machine learning based method to predict the forest structure parameters from L-band polarimetric and interferometric synthetic aperture radar (PolInSAR) data acquired by the airborne UAVSAR system over the Réserve Faunique des Laurentides in Québec, Canada. The main objective of this paper is to show that relevant parameters ...

Notre objectif est d'évaluer la contribution des arbustes de Guiera senegalensis aux flux d'eau et de carbone dans un parc agroforestier à petit mil (Pennisetum glaucum L.R. Br.) et dans une jachère. Le site expérimental est situé au sud-ouest du Niger, sur un bassin-versant sahélien de 2 km2. À l'échelle de l'arbuste de Guiera senegalensis, le tau...
Hydroacoustics has become a requisite method to assess fish populations and allows to describe the relationships of fish with other elements of the aquatic ecosystem. This nonintrusive method is currently an integral part of the sampling procedures recommended for fish stock assessment by the Water Framework Directive and has been standardized by t...
The research and improvement of methods to be used for crop monitoring are currently major challenges, especially for radar images due to their speckle noise nature. The European Space Agency’s (ESA) Sentinel-1 constellation provides synthetic aperture radar (SAR) images coverage with a 6-day revisit period at a high spatial resolution of pixel spa...
Tropical coastal lagoon environments provide a number of ecosystem services, but are threatened by the pressure lmposed by human activities and climatic change; these systems are particularly vulnerable because of a high demographic growth. Therefore, the understanding of their ecological behavior and the characterization of lagoon health indicator...
