Smart acoustic lining for UHBR technologies engine: from the design of an electroacoustic metasurface to experimental characterization under flow
The SALUTE project aims at evaluating performance of electroacoustic metasurface, employing a surface array of controlled electroacoustic actuators, for smart acoustic lining under grazing turbulent flow to be used in UHBR Technologies Engines. Theoretical ...
Society of Photo-Optical Instrumentation Engineers (SPIE)2023Information Theory in Transmembrane Transport
The past decades have seen the advent of information theory in various fields, from quantum physics to cosmology.At an intermediary scale between atomic and cosmological scales are biological systems and in particular the cell, as a constitutive element of ...
EPFL2023Deep learning accelerated prediction of the permeability of fibrous microstructures
Véronique Michaud, Baris Çaglar, Guillaume Clément Broggi
Permeability of fibrous microstructures is a key material property for predicting the mold fill times and resin flow path during composite manufacturing. In this work, we report an efficient approach to predict the permeability of 3D microstructures from d ...
2022In flow acoustic characterisation of a 2D active liner with local and non local strategies.
Hervé Lissek, Maxime Volery, Gaël Matten
The design and the grazing flow aeroacoustical characterization of a 2D active liner based on an array of electroacoustic absorbers are presented in this paper. The strategy stands on a pressure-based, current-driven digital architecture for impedance cont ...
2022Current Limiting in Overload Conditions of an LLC-Converter-Based DC Transformer
The dc transformers based on an LLC converter operated in open loop near resonant frequency have several crucial advantages compared to other topologies. These advantages are the stiff voltage ratio with a natural power flow, the dc grid isolation via medi ...
2021Experimental assessment of an active (acoustic) liner prototype in an acoustic flow duct facility
Hervé Lissek, Maxime Volery, Gaël Matten
In this paper, experimental results of broadband noise reduction in an acoustic flow duct are presented. An active liner composed of an array of electroacoustic absorbers is used. The control law is based on the pressure-based, current driven digital archi ...
SPIE2021Spalling of concrete cover induced by reinforcement
Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia
This paper investigates the phenomenon of cover spalling in reinforced concrete induced by bond or by the action of an inner pressure. This research is based on an experimental programme comprising a series of bond tests and a series of tests with inner-pr ...
2021Simultaneous autoregressive models for spatial extremes
Emeric Rolland Georges Thibaud
Motivated by the widespread use of large gridded data sets in the atmospheric sciences, we propose a new model for extremes of areal data that is inspired by the simultaneous autoregressive (SAR) model in classical spatial statistics. Our extreme SAR model ...
WILEY2020Electroacoustic resonators: system identification and stability
Hervé Lissek, Sami Driss Karkar, Thomas Laurence, Gaël Matten
An Electroacoustic Resonator consists of a loudspeaker used as a membrane resonator, through anacoustic pressure-based controlled electrical current, in order to vary its vibrating velocity in re-sponse to an exogenous sound field. This way, the loudspeake ...
Canadian Acoustical Association2019Active Electroacoustic Resonators and their Applications to Non-Hermitian Acoustics
We will discuss our recent experimental progress on developing active acoustic resonators that provide in- dependently tunable acoustic properties, namely the possibility to control at will their resonance frequency, absorption losses, and radiative losses ...
