DESCRIPTION:This talk would focus on one of the main themes of this  works
 hop: the diverse applications of the Wiener-Hopf technique for aerospace i
 n general and turbofan noise problems in particular. First\, I will give a
  theoretical model based on the Wiener-Hopf method (and matrix kernel  fac
 torisation) to unveil possible noise control mechanisms due to trailing-ed
 ge chevrons on the bypass duct of aircraft engine. Next\, I will propose a
  new testing approach that relies on the forward propagation model based o
 n the Wiener-Hopf method. The key contribution is the development of the i
 nverse acoustic scattering approach for a sensor array by combining compre
 ssive sensing in a non-classical way. Last but not least\, I will demonstr
 ate some of the new aerospace applications of the Wiener-Hopf technique wi
 th recently popular deep neural networks.
