The Conference Journées Ondes du Sud-Ouest 2025 is organized at the University of Pau and Pays de l’Adour from March 18th to 20th Conference website: https://joso-2025.github.io/ The Journées Ondes du Sud-Ouest are an opportunity to bring together researchers from south-west France who are contributing to the simulation of wave propagation…
Florian Faucher got awarded the 2024 EAIP Young Scientist Award of the Eurasian Association on Inverse Problems (EAIP) during the 11th International Conference “Inverse Problems: Modeling and Simulation”. https://www.eurasianip.org/eaip-awards/eaip-young-scientist-award.html
Dr Janosch Preuss from University College London is visiting Makutu from May 20th to 25th. He will give the following seminar: A hybridized Nitsche method for acoustic metamaterials abstract: Acoustic metamaterials have some seemingly magical properties. For example, they can be used to render objects invisible to incoming sound waves…
Prof. Maarten V. de Hoop from Rice University is visiting Makutu on March 18th and 19th. He will give the following seminar: Geometry and seismology on gas giants, and inverse problems abstract: It is often useful to treat planets as geometric objects where the geometry is defined so that the…
The internal geometry of a wind instrument can be estimated from acoustic measurements. For woodwind instruments, this involves characterizing the inner shape (bore) but also the side holes (dimensions and location). In this study, the geometric parameters are recovered by a gradient-based optimization process, which minimizes the deviation between simulated…
We did benchmark Full Waveform Inversion (FWI) tests on a synthetic model featuring 2 holes (tunnels): Synthetic data generated by Hou10ni in the time domain and FWI performed by Hawen in the frequency domain.
We have designed an algorithm to adapt the mesh between two iterations of a time domain full-waveform inversion. Once the model (representing the physical parameters) is updated, we use it to build a size map and we construct a new mesh thanks to MMG.
