Fig. 6From: X-ray microtomography and linear discriminant analysis enable detection of embolism-related acoustic emissionsAverage cumulative acoustic emissions (CumAE, red; 10-min averages), first derivative or AE activity (CumAEder 1, black; moving window interval: 15Â min) and third derivative (CumAEder3, grey, moving window interval: 48Â h) of Fraxinus excelsior L. registered by sensor AE1 during dehydration. The endpoint of VCAE corresponds to the local maximum of the third derivate after the maximum in AE activity, which was not yet reached as indicated by the continuous increase in third derivative at the end of the acoustic curveBack to article page
