Localization of emergency acoustic sources by micro aerial vehicles

Dario Floreano, Felix Stephan Schill, Meysam Basiri

For micro aerial vehicles (MAVs) involved in search and rescue missions, the ability to locate the source of a distress sound signal is significantly important and allows fast localization of victims and rescuers during nighttime, through foliage and in du ...

A compressed beamforming framework for ultrafast ultrasound imaging

Jean-Philippe Thiran, Yves Wiaux, Dimitris Perdios, Rafael Eduardo Carrillo Rangel, Marcel Arditi, Adrien Georges Jean Besson, Olivier Bernard

Classical beamforming methods, based on Delay- And-Sum (DAS) require an extensive number of samples and delay calculations to obtain high-quality images. Compressed Beamforming (CB) proposes an alternative to DAS, based on compressed sensing, which aims at ...

20-300 MHz Frequency Generator with-70 dBc Reference Spur for Low Jitter Serial Applications

Catherine Dehollain, Gürkan Yilmaz

This paper presents a frequency synthesizer based on a phase locked loop (PLL) targeting low jitter applications. The frequency generator covers a range wider than a decade, more explicitly from 20 to 300 MHz. Thanks to a 4-stage ring oscillator, it can pr ...

Can Dissipative Properties of Single Molecules Be Extracted from a Force Spectroscopy Experiment?

Giovanni Dietler, Andrzej Kulik, Fabrizio Benedetti, Dmitry Klinov

We performed dynamic force spectroscopy of single dextran and titin 127 molecules using small-amplitude and low-frequency (40-240 Hz) dithering of an atomic force microscope tip excited by a sine wave voltage fed onto the tip-carrying piezo. We show that f ...

Demonstration of optical multicasting using Kerr frequency comb lines

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Yan Yan, Zhe Zhao, Long Li, Lin Zhang, Amirhossein Mohajerin Ariaei

We experimentally demonstrate optical multicasting using Kerr frequency combs generated from a Si3N4 microresonator. We obtain Kerr combs in two states with different noise properties by varying the pump wavelength in the resonator and investigate the effe ...

1.3 Octave Supercontinuum Generation in Highly Ge-doped Photonic Crystal Fiber

Camille Sophie Brès, Deniz Aydin, Thibault Emmanuel North

We present a flat, visible 1.3-octave supercontinuum generated in a GeO2-doped photonic crystal fiber owing to an overlap of the modulation instability and Raman gain regions resulting in efficient energy transfer to new frequency components ...

A Primal-dual Framework For Mixtures Of Regularisers

Volkan Cevher, Cosimo Aprile, Quoc Tran Dinh, Luca Baldassarre, Baran Gözcü

Effectively solving many inverse problems in engineering requires to leverage all possible prior information about the structure of the signal to be estimated. This often leads to tackling constrained optimization problems with mixtures of regularizers. Pr ...

Acquisition of multiple phase derivatives from a single frame in digital holographic interferometry

Pramod Rastogi, Rishikesh Dilip Kulkarni

This paper proposes a technique to extract two-dimensional multiple phase derivatives (strains, slopes, and shearing strains) from a single frame of the interference fringe pattern recorded in an optical setup with multiple illumination beams. In the propo ...

Sinusoidally Modulated Graphene Leaky-Wave Antenna for Electronic Beamscanning at THz

Julien Perruisseau-Carrier, Marc Esquius Morote, Juan Sebastian Gomez Diaz

This paper proposes the concept, analysis and design of a sinusoidally modulated graphene leaky-wave antenna with beam scanning capabilities at a fixed frequency. The antenna operates at terahertz frequencies and is composed of a graphene sheet transferred ...
