Vibration isolation via linear and nonlinear periodic devices

The current manuscript deals with the design of passive mechanical filters for vibration attenuation a low frequencies. Traditionally, this has been addressed employing dissipation as the attenuation mechanism. While such strategy provides broadfrequency e ...

Organic-based microcavities with vibronic progressions: Photoluminescence

We theoretically study the photoluminescence properties of organic-based microcavities with vibronic progressions. We analyze the relaxation from the exciton reservoirs to the polariton anticrossing region; the presence of vibronic levels qualitatively enr ...

Micromechanics and damping properties of composites integrating shear thickening fluids

Pierre-Etienne Bourban, Razvan Cristian Neagu

Damping is an important parameter for vibration control, noise reduction, fatigue endurance or impact resistance of composite materials. In this study, a micromechanical model was used to predict the damping of a composite material containing shear thicken ...

Factoring end-user expectations into the sound design process of computer keyboards

Hervé Lissek, Romain Boulandet

The poor acoustic comfort of usual commercial products is often perceived as annoying. Today, more and more companies have realized that sound can be an important component of product attributes and image. They are interested in having acoustic guidelines ...

GFRP posts for railway noise barriers – experimental validation of load-carrying performance and durability

Thomas Keller, Till Vallée, Florian Riebel

As part of a 15-year railway noise remediation plan, 300km of noise barriers will be installed in Switzerland over the next few years. To enable pultruded glass fiber- reinforced polymer (GFRP) materials to be used for the noise barrier posts, a specificat ...

Modal parameter identification for a GFRP pedestrian bridge

Thomas Keller, Yu Bai

Dynamic experiments were conducted on an all-FRP composite pedestrian bridge. The structure was excited by impact and human-induced vibrations. The peak-picking method and stochastic subspace identification method were used to extract structural dynamic ch ...

Influence des fluctuations sur l'échantillonnage et la quantification dans le système visuel (2008)

Cédric Duchene

Recent studies have shown that biological neural systems are able to use noise and non linearities to improve the information processing which is occurred in. This thesis focus on this topic. We investigate the links between some operations of signal proce ...

Audiovisual Gestalts

Pierre Vandergheynst, Gianluca Monaci

This paper presents an algorithm to correlate audio and visual data generated by the same physical phenomenon. According to psychophysical experiments, temporal synchrony strongly contributes to integrate cross-modal information in humans. Thus, we define ...

Study of vehicle noise for different operating conditions

André-Gilles Dumont, Edward Chung, Ashish Bhaskar

The noise emission level from a vehicle is significantly influenced by different driving conditions and drivers’ behaviour. Almost all the in practice road traffic noise estimation models do not differentiate between different operating conditions. In this ...

Structural and acoustic behavior of chiral truss-core beams

Alessandro Spadoni

This paper analyzes the structural and acoustic behavior of sandwich beams with a chiral truss-core. This particular core configuration is considered to exploit some of the unique properties of the chiral geometry and to explore their potential benefits in ...
