Improved AUV Autonomy Provided by an Underwater Acoustic Link ̈ § ̈ § ̈ ̈
GESMA (Groupe d’Etudes Sous-Marines de l’Atlantique), initiated a project named TRIDENT (TRansmission d’Images et de Données EN Temps réel) a few years ago. The project’s objective is to develop a high data rate link allowing the transmission of different information (text, images...). A real-time receiver platform based on a spatiotemporal equalizer developed by ENST Bretagne, was carried out ...
متن کاملHigh-frequency thresholds: circumaural earphone versus insert earphone.
Benefits of high-frequency audiometry in monitoring hearing sensitivity of patients administered ototoxic medications are well established. High-frequency thresholds have been reported to be variable, due in part to small differences in the placement of the earphone diaphragm over the opening of the ear canal. Reliability may be improved by using insert earphones (ER-2) when obtaining high-freq...
متن کاملImproved Fuzzy Neural Modeling for Underwater Vehicles
The dynamics of the Autonomous Underwater Vehicles (AUVs) are highly nonlinear and time varying and the hydrodynamic coefficients of vehicles are difficult to estimate accurately because of the variations of these coefficients with different navigation conditions and external disturbances. This study presents the on-line system identification of AUV dynamics to obtain the coupled nonlinear dyna...
متن کاملReference threshold levels for an ER-3A insert earphone.
The purpose of this study was to obtain normal hearing thresholds for an ER-3A insert earphone as a contribution for future standardization and for comparison with previous studies and interim ANSI and ISO insert earphone reference equivalent threshold sound pressure levels (RETSPLs). Hearing thresholds were obtained on each ear of 48 normal-hearing subjects from 125 to 8000 Hz using ER-3A and ...
متن کاملOPTIMIZED FUZZY CONTROL DESIGN OF AN AUTONOMOUS UNDERWATER VEHICLE
In this study, the roll, yaw and depth fuzzy control of an Au- tonomous Underwater Vehicle (AUV) are addressed. Yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. The discussed AUV has four aps at the rear of the vehicle as actuators. Two rule bases...
