Monitoring pavement condition during its service life is paramount in order to antici-pate and optimize the potential maintenance work. For this purpose, different non-destructive techniques (NDT) are used to evaluate the structure distresses condition and to provide necessary information for the maintenance tasks. On their own, they are limited to...
Scouring processes are a major cause of instability and destruction of structures (bridges, earthworks and buildings) especially during major floods. The consideration of these erosion phenomena remains too empirical, especially because they are particularly complex and involve many disciplinary fields: soil mechanics, fluid mechanics, structures.....

In the context of building acoustics and the acoustic diagnosis of an existing room, this paper introduces and investigates a new approach to estimate mean absorption coefficients solely from a room impulse response (RIR). This inverse problem is tackled via virtually-supervised learning, namely, the RIR-to-absorption mapping is implicitly learned ...
Rotating machinery are present in many engineering applications. Such rotor systems often subjected to high vibration loads that can be at the origin of noise or failure. For these reasons, it is of main importance to predict with accuracy the critical speeds and the dynamic response amplitude of such structures. However, they are often subjected t...
Demand estimation is an important step for multiple applications in urban studies. However, the level of accuracy required depends on the objective of the study. In dynamic traffic microsimulation, the estimation of demand needs to be accurate, as it is intended to describe individuals' trips on a very small-scale. In this case, poor estimation of ...
Dynamic system fault diagnosis is often faced with a large number of possible faults. The purpose of this paper is to propose an efficient method for such situations. To avoid intractable combinatorial problems, sparse estimation techniques appear to be a powerful tool for isolating faults, under the assumption that only a small number of possible ...
The development of Advanced Traveler Information Systems (ATIS) with en-route navigation systems has opened the door to new traffic regulation policies such as collective route guidance based on social costs, i.e. routes that minimize total travel time. However, a critical element for their efficiency is the compliance of travelers with route recom...
Face à l'urbanisation et au changement climatique qui ont des effets néfastes sur le bilan énergétique (îlot de chaleur urbain) et le cycle de l'eau (crues plus intenses et plus fréquentes, périodes d'étiage plus longues et plus marquées, recharge des nappes limitées), des solutions d'adaptation sont nécessaires: elles jouent sur les différents pro...
