Full band denoising of room impulse response in the wavelet domain with dictionary learning
Théophile Dupré, Romain Couderc, Miguel Moleron +3
Conventional wavelet-domain methods for room impulse response denoising rely on thresholding detail coefficients, which is unsuited for low frequencies. In this work, we introduce…
Nonlinear Localized Modes in Two-Dimensional Hexagonally-Packed Magnetic Lattices
C. Chong, Yifan Wang, Donovan Marechal +6
We conduct an extensive study of nonlinear localized modes (NLMs), which are temporally periodic and spatially localized structures, in a two-dimensional array of repelling magnets…
Tunable, synchronized frequency down-conversion in magnetic lattices with defects
Marc Serra-Garcia, Miguel Molerón, Chiara Daraio
We study frequency conversion in nonlinear mechanical lattices, focusing on a chain of magnets as a model system. We show that by inserting mass defects at suitable locations, we c…
A mechanical autonomous stochastic heat engine
Marc Serra-Garcia, André Foehr, Miguel Molerón +3
Stochastic heat engines are devices that generate work from random thermal motion using a small number of highly fluctuating degrees of freedom. Proposals for such devices have exi…
Subwavelength edge detection through trapped resonances in waveguides
Miguel Molerón, Chiara Daraio
Lenses that can collect the perfect image of an object must restore propagative and evanescent waves. However, for efficient information transfer, e.g., in compressed sensing, it i…
