We investigate the time intermittency of turbulent transport associated with the birth-death of self-organized coherent structures in the atmospheric boundary layer. We apply a threshold analysis on the increments of turbulent fluctuations to extract

International audience; This paper considers the problem of unsupervised spectral unmixing for hyperspectral image analysis. Each observed pixel is assumed to be a noisy linear mixture of pure material spectra, namely endmembers. The mixing coefficie

International audience; This paper proposes an anomaly detection algorithm for hyperspectral images. It is unsupervised (the researched spectra are not required a priori), discriminates the anomalies according to their spectra and has a Constant Fals

While several mental functions, from visual perception up to working memory, are characterized by parallel computation performed by integrated moduli in the cortex, consciousness is sustained by a serial process of global integration, insofar as a si
