Experimental characterization of periodic metamaterials in acoustic open water tank

Clément Larcade, Laetitia Roux, Charles Cröenne, Monique Pouille, Anne-Christine Hladky-Hennion

The measurement of acoustic performance of underwater panels, such as their reflection and transmission coefficients, has always been a challenge. The finite size of the tank imposes a low frequency limit, while diffraction by the edges of the panel disturbs measurements. Despite these difficulties…

Microstreaming induced by a micro-cantilever vibrating elliptically in a viscous fluid

Jules Ghesquiere, Gustav Modler, Saeid Mollaei, David Guérin, Olivier Bou Matar, Henrik Bruus, Michael Baudoin, Sarah Cleve

The acoustically excited vibrations of a micrometric object in a viscous liquid induce a net fluid flow known as microstreaming. This phenomenon can be harnessed for a variety of microscale applications, including particle transport, fluid mixing and the propulsion of micro-swimmers. Acoustic…

Enhancing support vector clustering labeling efficiency with scalable heuristics

Abou Bakr Seddik Drid, Abdelhamid Djeffal, Abdelmalik Taleb-Ahmed

Support Vector Clustering (SVC) is a powerful unsupervised learning method for detecting arbitrarily shaped clusters, making it highly relevant for complex pattern analysis tasks. However, its widespread use has been constrained by the high computational cost associated with its labeling phase.…
