The caisson – review of a unique wooden construction typology in China

Corentin Jean Dominique Fivet, Jingxian Ye

The caisson is a wooden construction system that covers opera stages for rain protection and sound control. Caissons in China display a diverse range of geometric expressions, delicate manufacturing, structural behaviours, and acoustic qualities. Despite t ...

Joint Estimation Of The Room Geometry And Modes With Compressed Sensing

Pierre Vandergheynst, Hervé Lissek, Helena Peic Tukuljac, Vu Thach Pham

Acoustical behavior of a room for a given position of microphone and sound source is usually described using the room impulse response. If we rely on the standard uniform sampling, the estimation of room impulse response for arbitrary positions in the room ...

Reinforcing Civil Engineering Curricula With Courses Including Project-Based Software Applications

Gerard Guell Bartrina

Civil engineering (CE) is one of the broadest engineering fields, if not the most, and requires undergraduate students to be exposed to a variety of topics; each can be easily recognized as a major in its own. Establishing a successful curriculum is a majo ...

Efficient Multi-dimensional Diracs Estimation with Linear Sample Complexity

Martin Vetterli, Thierry Blu, Hanjie Pan

Estimating Diracs in continuous two or higher dimensions is a fundamental problem in imaging. Previous approaches extended one dimensional methods, like the ones based on finite rate of innovation (FRI) sampling, in a separable manner, e.g., along the hori ...

Broadband Low-Frequency Electroacoustic Absorbers Through Hybrid Sensor-/Shunt-Based Impedance Control

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

This paper proposes a hybrid impedance control architecture for an electroacoustic absorber, that combines an improved microphone-based feedforward control with a currentdriven electrodynamic loudspeaker system. Feedforward control architecture enables sta ...

Friction law and hysteresis in granular materials

Matthieu Wyart, Eric DeGiuli

The macroscopic friction of particulate materials often weakens as the flow rate is increased, leading to potentially disastrous intermittent phenomena including earthquakes and landslides. We theoretically and numerically study this phenomenon in simple g ...

Generation of acoustic helical wavefronts using metasurfaces

Juan Ramon Mosig, Hervé Lissek, Seyyed Hussein Seyyed Esfahlani

It has been shown that acoustic waves with helical wavefronts can carry angular momentum, which can be transmitted towards a propagating medium. Such a wave field can be achieved by using a planar array of electroacoustic transducers, forming a given spati ...

Interplay between Narrative and Bodily Self in Access to Consciousness: No Difference between Self- and Non-self Attributes

Olaf Blanke, Andrea Serino, Roy Salomon, Jean-Paul Noel

The construct of the self is conceived as being fundamental in promoting survival. As such, extensive studies have documented preferential processing of self-relevant stimuli. For example, attributes that relate to the self are better encoded and retrieved ...

On the Optimisation of Multi-Degree-of-Freedom Acoustic Impedances of Low-Frequency Electroacoustic Absorbers for Room Modal Equalisation

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

Low-frequency electroacoustic absorbers have recently been developed as a solution for the modal equalisation. Firstly investigated in waveguides, the technique consists in matching the acoustic impedance at a closed-box loudspeaker diaphragm to the charac ...
