Rodrigues, Estevão P. (author), Simoes dos Santos, D. (author), Buiochi, Flávio (author)The measurement of acoustic fields generated by ultrasonic transducers is important for determining the focal length, lateral resolution, and amplitudes of the lateral and grating lobes. The acoustic field is commonly characterized by a set of scans using a needle hydrophone. The output of the hydrophone can be connected to an analog filter to...journal article 2023

Li, Jiaze (author), Claude, Nicolas (author), Tassi, Pablo (author), Cordier, Florian (author), Crosato, A. (author), Rodrigues, Stéphane (author)Active geomorphological interventions, such as reprofiling of river bars, are often used to increase bar dynamics and prevent vegetation encroachment. River restoration management should be planned based on the knowledge of what processes will follow the intervention and on the anticipation of the consequences. However, in many cases, the...journal article 2023
