Robust tunable acoustic impedance control on electroacoustic resonators for aircraft noise reduction
Air traffic noise emissions are responsible for a significant part of the overall environmental noise, especially in the vicinity of airports. Exposure to environmental noise is known to negatively impact health and to be associated with cardiovascular dis ...
EPFL2023Plasma-based Electroacoustic Actuator for Broadband Sound Absorption
Environmental noise, mostly related to human activities, has an immense impact on public health. The development of noise reduction technologies is paramount in addressing this problem. Because of practical and economic reasons, a compact, broadband, light ...
EPFL2022Deep learning-based galaxy image deconvolution
Frédéric Courbin, Pascale Jablonka, Jean-Luc Starck, Utsav Akhaury, Kevin Michalewicz
With the onset of large-scale astronomical surveys capturing millions of images, there is an increasing need to develop fast and accurate deconvolution algorithms that generalize well to different images. A powerful and accessible deconvolution method woul ...
FRONTIERS MEDIA SA2022Synthetic realistic noise-corrupted PPG database and noise generator for the evaluation of PPG denoising and delineation algorithms
David Atienza Alonso, Giulio Masinelli, Adriana Arza Valdes, Fabio Isidoro Tiberio Dell'Agnola
This database is meant to evaluate the performance of denoising and delineation algorithms for PPG signals affected by noise. The noise generator allows applying the algorithms under test to an artificially corrupted reference PPG signal and comparing its ...
2021Compound Admittance Matrix Estimation of Three-phase Untransposed Power Distribution Grids using Synchrophasor Measurements
Jean-Yves Le Boudec, Mario Paolone, Fabrizio Sossan, Rahul Kumar Gupta
The paper considers the problem of estimating the parameters of the compound admittance matrix of three-phase untransposed low-and medium-voltage electrical distribution networks using synchrophasor measurements from phasor measurement units (PMUs). The wo ...
2021Influence of Large Relative Tip Clearances for a Micro Radial Fan and Design Guidelines for Increased Efficiency
Jan Van Herle, Jürg Alexander Schiffmann, Patrick Hubert Wagner
The blade tip clearance loss was studied experimentally and numerically for a micro radial fan with a tip diameter of 19:2mm. Its relative blade tip clearance, i.e., the clearance dividedby the blade height of 1:82mm, was adjusted with different shims. The ...
2020A Linear-Quadratic Gaussian Approach to Dynamic Information Acquisition
Thomas Alois Weber, Viet Anh Nguyen
We consider optimal information acquisition for the control of linear discrete-time random systems with noisy observations and apply the findings to the problem of dynamically implementing emissions-reduction targets. The optimal policy, which is provided ...
2018Assessment of a metamaterial-inspired active acoustic liner concept for application to aircraft engine noise reduction
Hervé Lissek, Romain Boulandet, Sami Driss Karkar, Gaël Matten
Acoustic liners are a widespread solution for noise mitigation at aircraft engine level, thanks to lightweight and relatively small dimensions for integration within nacelles. Although conventional liners might be designed to target multiple tonal frequenc ...
