Design of a built-in electroacoustic resonator for active noise reduction

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet

The paper focuses on the design of a built-in electroacoustic device for active noise reduction purposes. The device basically encompasses a loudspeaker connected to a synthetic electrical impedance that enhances its ability to dissipate part of the incomi ...

On Stochastic Processes Driven by Ballistic Noise Sources

Max-Olivier Hongler, Roger Filliger, Philippe Blanchard, Julio Rodriguez

Among the rich collection of noise sources that can be used to drive stochastic differential equations (SDE), we here focus on Markov processes that themselves are functions of the standard Brownian motion and of the Telegrapher’s process. Our present nois ...

Current variability in a wide and open lacustrine embayment in Lake Geneva (Switzerland)

David Andrew Barry, Alfred Johny Wüest, Ulrich Lemmin, Roham Bakhtyar, Amir Mehdi Razmi, Nicolas Le Dantec

Field measurements and numerical simulations were used to determine the effects of dominant meteorological conditions on the hydrodynamics of a wide (aspect ratio ~2), relatively deep (seasonally stratified) and open lake embayment (Vidy Bay, Lake Geneva). ...

Superior GRAPPA reconstruction with reduced g-factor noise using 2D CAIPIRINHA for 3D EPI

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Daniel Gallichan, Mayur Narsude

Efficient GRAPPA or SENSE reconstruction is largely dependent on coil geometry in the direction in which phase encoding steps reduction is performed during partially parallel acquisition. In this study we demonstrate the ability to perform a 2D CAIPIRINHA ...

Experimental investigation of added mass effects on a hydrofoil under cavitation conditions

Mohamed Farhat, Eduard Egusquiza

The influence of leading edge sheet cavitation and supercavitation on the added mass effects experienced by a 2-D NACA0009 truncated hydrofoil has been experimentally investigated in a hydrodynamic tunnel. A non-intrusive excitation and measuring system ba ...

On the damping of room resonances with electroacoustic absorbers in the low frequency range

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet, Iris Rigas

In closed spaces, standing waves occur at low frequencies, thus creating annoying acoustic resonances. Such unwanted phenomena are likely to affect the annoyance of noise sources in the low frequency range. Up to date, low-frwquency treatments are mainly b ...

Passive damping of composite blades using embedded piezoelectric modules or shape memory alloy wires: a comparative study

Véronique Michaud, Antoine Sigg, Andrea Bergamini

Emission reduction from civil aviation has been intensively addressed in the scientific community in recent years. The combined use of novel aircraft engine architectures such as open rotor engines and lightweight materials offer the potential for fuel sav ...
