The Eurasian otter Lutra lutra faced a significant decline in Italy during the 20th century, leading to local extinctions. After fifty years of otter disappearance from the Tiber basin, this study documents a sighting near Rome, obtained during a lon

Aircraft Vibration Detection and Diagnosis for Predictive Maintenance using a GLR Test

Autor: Eric Chaumette, Simone Urbano, J-Y. Tourneret, Philippe Goupil

Publikováno v: IFAC-PapersOnLine. 51:1030-1036

This paper studies a statistical approach to detect and diagnose a particular type of vibration impacting the control surfaces of civil aircraft. The considered phenomenon is called Limit Cycle Oscillation (LCO). It consists of an unwanted sustained

International audience; This paper studies the performance of the generalized likelihood ratio test (GLRT) for the conditional signal model. By conditional signal model, we mean that under both hypotheses, the observations are a linear superposition
