A better understanding of the movements and behavior of cetaceans through their vocalizations: this is the focus of Mathilde’s thesis, which is based on passive acoustics, a non-intrusive technique.

The ocean covers 70.8% of the Earth’s surface: a vast space that is still poorly understood. The aim of Perrine’s thesis is to combine different types of ocean observation data (satellite images, buoys, boats, etc.) and use artificial intelligence to gain a better understanding of the underlying physical phenomena.

Mathilde is a PhD student in mechanical sciences at ENSTA Bretagne / IRDL (Naval Group CIFRE* thesis). Her thesis aims to contribute to the development of new sizing methods for a new generation of marine propellers produced using arc-wire 3D printing.

In his thesis, Pierre-Yves seeks to identify when and how a fracture appears between two very different materials: a metal and an elastomer, such as rubber. With his research’s direct application being tires, Pierre-Yves performs experiments on representative samples of vehicle tires to study interface failures between the rigid part (the cord or structure) of the tire and the flexible part (rubber).

Hugo chose to combine his interest in mathematics with a better understanding of the environment. Currently a PhD student in the field of acoustic waves in the marine environment, he uses artificial intelligence to automatically define the origin of captured waves.
