Proceedings of the 2nd ANIMA scientific workshop (23rd CEAS-ASC Workshop at Roma Tre University)
Description
This deposit is the programme of the 23rd CEAS-ASC Workshop occurred at the Roma Tre University. In 2019, this event was the yearly-based scientific workshop of the ANIMA project.
The topic of this workshop help on the 26-27 September 2019 was about New Materials for Applications in Aeroacoustics.
For IP reason, the presentation themselves are kept on the dedicated Website of the Roma Tree University
The programme was the following:
