(Conférence Chaire Aisenstadt) On the hunt for chirps
Colloque par Stéphane Jaffard (Université Paris-Est Crétell)
The detection of specific oscillatory behaviours in signals is a key issue in turbulence, gravitational waves, or physiological data, where they turn out to be the signature of important phenomena localized in time or space. We will show how some recently introduced methods of harmonic analysis allow us to characterize and classify such behaviors, and ultimately yield numerical methods to perform their detection.
