This project is concerned with the fundamental study of an innovative damage detection and imaging method for structural monitoring. The principle is based on the use of ambient acoustic and vibrational noise as a substitute to incident ultrasound waves generated in conventional non-destructive testing methods.

In numerous fields (e.g., material sciences, medical imaging), non-invasive acquisition devices such as magnetic resonance, X-ray tomography or microtomography are required for observation, measurements or diagnostic aids. These acquisition devices usually generate volumic data, i.e., 3D images, composed of regularly spaced data in a cuboidal domain. 3D volumes come from the segmentation of such 3D images. They can also be generated from scientific modelling because numerous simulation schemes rely on the regularity of the data support.

Cardiac valve diseases are known to be an important public-health problem. Mitral Valve (MV) regurgitation (MR), also known as mitral insufficiency, is one of the most important of them. The regurgitation is either caused by a pathology of the valve itself (primary MR), or it is the consequence of a pathology of the myocardium (secondary MR).

The Internet of Things connects physical devices offering sensing or actuating with their vicinity. The ever-growing capabilities of devices allow to imagine new architectures including them as first class citizens. New added-value applications can then be envisioned in smart agriculture, smart buildings, smart cities, energy and water management, e-health and ageing well...

Tribology has a major role to play to reduce the total energy consumption worldwide. Yet, the lubricant behavior in extreme conditions is poorly known, and therefore unpredictable. In this project, we propose to couple a Brillouin Light Scattering set up with a tribometer to carry in situ spectroscopy characterization of lubricants in a highly confined contact. This experimental approach will lead to simultaneously measure the thermodynamic state of the lubricant, its structural dynamics and the resulting macroscopic friction causing high energy dissipation.
