Acoustic characteristics of circular dissipative reversing chamber mufflers

Denia, F. D.; Antebas, Antoine; Selamet, A.; Pedrosa Sanchez, Ana Maria (Institute of Noise Control Engineering, 2011)

[EN] In this work, a three-dimensional analytical model is presented for the propagation of sound in circular dissipative reversing chamber mufflers with perforated frontal plates and bulk-reacting fibrous material. The ...
Estimation of Walnut Structure Parameters Using Terrestrial Photogrammetry Based on Structure-from-Motion (SfM)

Fernández-Sarría, Alfonso; López- Cortés, I; Marti-Gavila, Jesus; Estornell Cremades, Javier (Springer-Verlag, 2022-10)

[EN] Remote sensing techniques are increasingly used for crop monitoring to improve the profitability of plantations. These studies are mainly based on spectral information recorded by satellites or unmanned aerial vehicles. ...
Simultaneous guidance of slow photons and slow acoustic phonons in silicon phoxonic crystal slabs

Laude, Vincent; Beugnot, J.C.; Benchabane, S.; Pennec, Y.; Djafari-Rouhani, B.; Papanikolaou, Nikos; Escalante Fernández, José María; Martínez Abietar, Alejandro José (Optical Society of America, 2011)

[EN] We demonstrate theoretically that photons and acoustic phonons can be simultaneously guided and slowed down in specially designed nanostructures. Phoxonic crystal waveguides presenting simultaneous phononic and photonic ...
