Uncertainties estimation in THz-TDS experiments in transmittance, refractive index and spectroscopic parameters

Noureddin Osseiran, Jeyan Bichon, Théo Hannotte, Mouhamed Abdel-Kader, Martin Witt, Sophie Eliet, Romain Peretti

<div><p>Data processing is a key for the spreading of the THZ-TDS systems to more analytical fields. However, till today no standard methods exist to extract error bar from standard measurements in TDS besides the transmission. We propose here a methodology to reply to this challenge.…

Optimisation d'un Nano-drone à ailes vibrantes, Optimization of a Flapping-Wing Nano-Drone

Marguerite Delabigne, Eric Cattan, Sofiane Ghenna, Marie Zwingelstein, Sébastien Grondel, Olivier Thomas

L’étude du vol des insectes est une source d’inspiration pour la conception des Nano-Air Vehicles (NAVs). La compréhension du vol des insectes montre qu’il combine des mouvements de torsion et de battement. Deux approches principales existent pour concevoir des ailes de NAV : l’une utilise des…, The study of insect flight is a source of inspiration for the design of Nano-Air Vehicles (NAVs). Understanding insect flight reveals that it combines both torsional and flapping movements. Two main approaches exist for designing NAV wings: one uses rigid wings with a four-bar mechanism to amplify…
