Low-complexity feature extraction unit for “Wake-on-Feature” speech processing

Simon Lecoq, Jean Le Bellego, Angel Gonzalez, Benoit Larras, Antoine Frappé

In the context of energy-constrained automatic speech recognition, a modeling and simulation tool is presented to evaluate the hardware complexity of a feature extraction unit. The objective is to evaluate the minimal amount of features necessary for voice-activity detection, considering limited…

The role of dispersion forces on the atomic structure of glassy chalcogenides: The case of GeSe4 and GeS4

Ziyad Chaker, Guido Ori, Christine Tugène, Sébastien Le Roux, Mauro Boero, Carlo Massobrio, Évelyne Martin, Assil Bouzid

Recent first-principles molecular dynamics simulations (FPMD) results on two chalcogenide glasses (glassy GeS4 and GeSe4) are revisited by accounting explicitly for van der Waals (vdW) dispersion forces. This effort is motivated by the observation that such contributions were found to be important…

Acoustic analogue of electromagnetically induced transparency and Autler-Townes splitting in pillared metasurfaces

Yabin Jin, Yan Pennec, Bahram Djafari-Rouhani

Electromagnetically induced transparency (EIT) and Autler-Townes splitting (ATS) originating from multilevel atomic systems have similar transparency windows in transmission spectra which causes confusion when discriminating between them, despite the difference in their physical mechanisms. Indeed…

Effective properties of metamaterials using inverse methods

Laetitia Roux, Christian Audoly, Anne-Christine Hladky, Nicole Kessissoglou

Metamaterials can be engineered for noise and vibration control due to their ability to manipulate waves in band gaps and due to local resonance effects. Metamaterials are often characterised in terms of effective parameters derived from an equivalent homogeneous medium. This work compares two…

An indoor variance-based localization technique utilizing the UWB estimation of geometrical propagation parameters

Brecht Hanssens, David Plets, Emmeric Tanghe, Claude Oestges, Davy Gaillot, M. Lienard, Taoyong Li, Heidi Steendam, Luc Martens, Wout Joseph

A novel localization framework is presented based on Ultra-Wideband (UWB) channel sounding, employing a triangulation method using the geometrical properties of propagation paths, such as time-delay of arrival, angle of departure, angle of arrival, and their estimated variances. In order to extract…

Unambiguous real-time terahertz frequency metrology using dual 10 GHz femtosecond frequency combs

Oliver Kliebisch, Dirk Heinecke, S Barbieri, Giorgio Santarelli, Hua Li, Carlo Sirtori, Thomas Dekorsy

Terahertz frequency metrology by radio frequency downconversion using femtosecond optical sampling relies on the harmonic factor retrieval between the terahertz frequency and the optical sampling rate. At typical femtosecond laser repetition rates, this imposes an ambiguity for frequency metrology…

Transmission gaps, trapped modes and Fano resonances in Aharonov-Bohm connected mesoscopic loops

T. Mrabti, Z. Labdouti, O. El Abouti, E. H. El Boudouti, F. Fethi, Bahram Djafari-Rouhani

A simple mesoscopic structure consisting of a double symmetric loops coupled by a segment of length do in the presence of an Aharonov-Bohm flux is designed to obtain transmission band gaps and Fano resonances. A general analytical expression for the transmission coefficient and the density of…

Study of the spectral bandwidth of a double-pass acousto-optic system

Justine Champagne, Jean-Claude Kastelik, Samuel Dupont, Joseph Gazalet

Acousto-optic tunable filters are known as efficient instruments for spectral and spatial filtering of light. In this paper, we analyze the bandwidth dependence of a double-pass filter. The interaction geometry chosen allows the simultaneous diffraction of the ordinary and the extraordinary optical…
