A sensorless online temperature estimator is presented in this paper, which estimates the temperature using a novel signal injection strategy. This allows to eliminate the temperature sensors in the machine, as well as their faults, increasing the sy

In recent years, the space industry has experienced a significant change mainly due to the incursion of private companies, which has shaken up the sector. This new situation allows for a reduction regarding the reliability of conventional instrumenta

The objective of this work is to build an acoustic barrier to detect and localize a target between two vertical arrays of sensors. To perform this detection/localisation, we record the signal between each source (of the source array) and each reveive

Ocean acoustic tomography using a double‐beamforming algorithm

Autor: Barbara Nicolas, Philippe Roux, Jerome Mars, Ion Iturbe

Publikováno v: The Journal of the Acoustical Society of America. 123:3912-3912

Since Munk and Wunsch proposed the basis for ocean acoustic tomography, many experiments have been performed to estimate sound speed fluctuations in the ocean, using ray identification and measurement of their travel times. However, technical limitat
