Combining a 3D Reflex Based Neuromuscular Model with a State Estimator Based on Central Pattern Generators

Auke Ijspeert, Florin Dzeladini, Amy Roning Wu, Tycho Jan Henricus Brug

A neuromuscular model (NMC) presented by H. Geyer and extended by S. Song shows very interesting similarities with real human locomotion. The model uses a combination of reflex loops to generate stable locomotion and is able to cope with external disturban ...

Assessment 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 ...

Nonreciprocal reconfigurable microwave optomechanical circuit

Tobias Kippenberg, Nathan Rafaël Bernier, László Dániel Tóth, Marie Adrienne Ioannou, Akshay Koottandavida

Devices that achieve nonreciprocal microwave transmission are ubiquitous in radar and radio-frequency communication systems, and commonly rely on magnetically biased ferrite materials. Such devices are also indispensable in the readout chains of supercondu ...

Design and experimental validation of an active acoustic liner for aircraft engine noise reduction

Hervé Lissek, Romain Boulandet, Sami Driss Karkar, Gaël Matten

The use of acoustic liners in aviation industry is a quite common solution for reducing the engines acoustic emissions. Although the current solutions based on single or multilayer liners are efficient and compact for the mid and high frequencies, noise mi ...

Design of Remote Quiet Zones Using Spot-Type Sound Reducers

Hervé Lissek, Romain Boulandet, Thomas Laurence

This paper presents a local control approach to generate remote quiet zones. To deal with situations where global control can hardly be achieved, it is proposed to use an arrangement of spot-type sound reducers as originally suggested by Olson and May. Ass ...

Design of active Multiple-degrees-of-freedom electroacoustic resonators for use as broadband sound absorbers

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

We present a novel control method achieving stable multiple-degrees-of-freedom electroacoustic resonators. Such broadband absorbers, composed of a feedback-controlled electrodynamic loudspeaker, have many practical applications to real-world acoustic engin ...

Influence of physiological noise on accelerated 2D and 3D resting state functional MRI data at 7 T

Rolf Gruetter, Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, João Pedro Forjaco Jorge, Olivier Benoit Thomas Reynaud

Physiological noise often dominates the blood-oxygen level-dependent (BOLD) signal fluctuations in high-field functional MRI (fMRI) data. Therefore, to optimize fMRI protocols, it becomes crucial to investigate how physiological signal fluctuations impact ...

Sampling and Reconstruction of Shapes with Algebraic Boundaries

Martin Vetterli, Arash Amini, Mitra Fatemi

We present a sampling theory for a class of binary images with finite rate of innovation (FRI). Every image in our model is the restriction of

\mathds{1}_{\{p\leq0\}}

to the image plane, where

\mathds{1}

denotes the indicator function and

p

is some r ...

Quantum rectifier in a one-dimensional photonic channel

By using a fully quantum approach based on an input-output formulation of the stochastic Schrodinger equation, we show rectification of radiation fields in a one-dimensional waveguide doped with a pair of ideal two-level systems for three topical cases: cl ...
