Using footstep-induced vibrations for occupant detection and recognition in buildings

Ian Smith, Yves Sylvain Gilles Reuland, Sai Ganesh Sarvotham Pai, Slah Drira

Occupant detection and recognition support functional goals such as security, healthcare, and energy management in buildings. Typical sensing approaches, such as smartphones and cameras, undermine the privacy of building occupants and inherently affect the ...

Mechanics of Allostery: Contrasting the Induced Fit and Population Shift Scenarios

Matthieu Wyart, Carolina Brito Carvalho dos Santos, Solange Marie Flatt, Stefano Zamuner, Riccardo Ravasio

In allosteric proteins, binding a ligand can affect function at a distant location, for example, by changing the binding affinity of a substrate at the active site. The induced fit and population shift models, which differ by the assumed number of stable c ...

Hearing assistance system

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

There is provided a hearing assistance system, comprising a transmission unit (10) comprising a microphone arrangement (17) for capturing audio signals from a voice of a speaker ( 11 ) using the transmission unit and being adapted to transmit the audio sig ...

Optimal Proximity Proofs

Serge Vaudenay

Provably secure distance-bounding is a rising subject, yet an unsettled one; indeed, very few distance-bounding protocols, with formal security proofs, have been proposed. In fact, so far only two protocols, namely SKI (by Boureanu et al.) and FO (by Fisch ...

Investigations on the physical factors influencing the ear canal occlusion effect caused by hearing aids

Hervé Lissek, Thomas Stefan Zurbrügg

The occlusion effect refers to the altered perception of one's own voice when the ear canal is fully or partially obstructed. While the loudness increase due to body conducted sounds requires an assessment by psychoacoustic methods, the ratio of sound pres ...

Method and Device for Removing Echo in an Audio Signal

Christof Faller

Acoustic echo control and noise suppression is an important part of any "handsfree" telecommunication system, such as telephony or audio or video conferencing systems. Bandwidth and computational complexity constraints have prevented that stereo or multi-c ...

Morphogenesis of the T4 tail and tail fibers

Petr Leiman

Remarkable progress has been made during the past ten years in elucidating the structure of the bacteriophage T4 tail by a combination of three-dimensional image reconstruction from electron micrographs and X-ray crystallography of the components. Partial ...

Structural and kinetic studies of induced fit in xylulose kinase from Escherichia coli

Henning Paul-Julius Stahlberg

The primary metabolic route for D-xylose, the second most abundant sugar in nature, is via the pentose phosphate pathway after a two-step or three-step conversion to xylulose-5-phosphate. Xylulose kinase (XK; EC 2.7.1.17) phosphorylates D-xylulose, the las ...

Contribution à l'étude des modes de rayonnement acoustique d'une structure

Olivier Schevin

Noise radiated by different industrial structures that surround us in daily life are more and more considered as environmental pollution. Standards defining a tolerable sound level for each of these noise sources are regularly called into question and resp ...

Multichannel Restoration with Limited A Priori Information

Michaël Unser

We introduce a method for multichannel restoration of images in which there is severely limited knowledge about the undegraded signal, and possibly the noise. We assume that we know the channel degradations and that there will be a significant noise reduct ...
