Bioenergy crops are expected to provide biomass as a replacement for fossil resources, but their impact on the water cycle is still under question. This study aimed at both quantifying the ability of bioenergy crops to use soil water and analysing the relationship between their root systems and soil water uptake. Water content was monitored continuously for(More)
It is admitted that human speech perception is a multimodal process that combines both visual and acoustic informations. In automatic speech perception, visual analysis is also crucial as it provides a complementary information in order to enhance the performances of audio systems especially in highly noisy environments. In this paper, we propose a unified(More)
In this paper, a multichannel speech enhancement system is presented , dedicated to in-car communication. An experimental study of the acoustic field inside the car interior leads us to propose a hybrid beamforming algorithm, taking two frequency ranges into account , according to the multichannel noise signal coherence. While in the high frequency range,(More)
