Ultrabroadband sound control with deep-subwavelength plasmacoustic metalayers

Romain Christophe Rémy Fleury, Hervé Lissek, Stanislav Sergeev

Controlling audible sound requires inherently broadband and subwavelength acoustic solutions, which are to date, crucially missing. This includes current noise absorption methods, such as porous materials or acoustic resonators, which are typically ineffic ...

Rise time reduction of thermal actuators operated in air and water through optimized pre-shaped open-loop driving

Georg Fantner, Nahid Hosseini, Tom Larsen

Electrothermal actuators have many advantages compared to other actuators used in micro-electro-mechanical systems (MEMS). They are simple to design, easy to fabricate and provide large displacements at low voltages. Low voltages enable less stringent pass ...

Design and Modeling of Serial Data Transceiver Architecture by Employing Multi-Tone Single-Sideband Signaling Scheme

Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust, Chen Cao, Thierry Barailler

This paper presents the design and analysis of a serial link transceiver (TRX) architecture employing analog multi-tone (AMT) signaling for chip-to-chip communication. Multi-tone single-sideband (SSB) signaling scheme is proposed in TRX architecture in ord ...

Aircraft panel with sensorless active sound power reduction capabilities through virtual mechanical impedances

Romain Boulandet

This paper deals with an active structural acoustic control approach to reduce the transmission of tonal noise in aircraft cabins. The focus is on the practical implementation of the virtual mechanical impedances method by using sensoriactuators instead of ...

Diffusion LMS strategies for parameter estimation over fading wireless channels

Ali H. Sayed

We propose a modified diffusion strategy for parameter estimation in sensor networks where nodes exchange information over fading wireless channels. We show that the effect of fading can be mitigated by incorporating local equalization coefficients into th ...

Heat Management for Process Intensification of Fast Exothermic Reactions in Microstructured Reactors

Julien Haber

Nowadays, the production in fine chemical and pharmaceutical industry is mostly carried out in large scale batch reactors having typically dimensions of a few meters to satisfy the demand of the market. Even though this technology has been widely used and ...

Tunable Electroacoustic Resonators through Active Impedance Control of Loudspeakers

Romain Boulandet

The current trend for multipurpose rooms requires enhanced acoustic treatments capable to meet ever more demanding specifications in terms of performance, compactness and versatility. The reason is the variety of activities to be hosted and the correspondi ...

Parametric joint-coding of audio sources

Christof Faller

The following coding scenario is addressed: A number of audio source signals need to be transmitted or stored for the purpose of mixing wave field synthesis, multi channel surround, or stereo signals after decoding the source signals. The proposed techniqu ...

On Successive Refinement of Diversity for fading ISI channels

Suhas Diggavi, Sanket Dusad

Abstract—Rate and diversity impose a fundamental tradeoff in communications. This tradeoff was investigated for IntersymbolInterference (ISI) channels in [4]. A different point of view was explored in [1] where high-rate codes were designed so that they ha ...

Audiovisual Gestalts

Pierre Vandergheynst, Gianluca Monaci

This paper presents an algorithm to correlate audio and visual data generated by the same physical phenomenon. According to psychophysical experiments, temporal synchrony strongly contributes to integrate cross-modal information in humans. Thus, we define ...
