Laboratory and field measurements of the acoustic performance of a CLT wood based floors were carried out within the scope of AdivBois acoustic technical commission with the objective of defining wood building constructions fulfilling defined requirements. French national regulation requires the use of the standardized tapping machine for impact so...
The aim of this work is to investigate the interaction between a premixed methane-air flame and particles within a packed bed. The opacity of the conventional packed bed reactors hinders the implementation of the optical diagnostics, so that no spatially resolved experimental data are available for numerical simulations. In this work, a two-dimensi...
Truck platooning for the transportation of loads is a strategy recently proposed by the automotive sector to cope with traffic congestion, fuel consumption, and operational costs. This new way of configuring trucks changes the typical pressures pavements structures experience. For this reason, the research efforts of the pavement sector should be a...

Despite recent publications, the strain transfer in distributed optical fiber sensors is still often overlooked and poorly understood. In the first part of this paper, strain transfer is shown to be driven by a second-order differential equation, whether the optical fiber is embedded into the host material or surface-mounted. In this governing equa...
Avec la multiplication des sources rayonnantes dans notre environnement, nous assistons au développement de moyens techniques permettant de tester, mesurer et visualiser le champ électromagnétique. Cette demande des industriels a engendré le développement de différentes technologies d'imagerie du champ et plusieurs approches ont été proposées dont ...

The paper presents some results concerning the development of a multi-sensor hybrid approach for measuring rail roughness using acoustic and vibration signals measured on-board. The main objective of the system is to provide better input data for noise mapping and maintenance strategies. Several improvements to existing systems are proposed, based ...
La gestion de la ville et des territoires est une tâche complexe nécessitant de multiples compétences dans des domaines très variés. Au cours de ce XXIème siècle, la ville et les territoires doivent faire face à des enjeux majeurs sur le plan environnemental et sociétal : la rareté de l'eau, le réchauffement climatique, la qualité de l'air et bien ...
