What is it about?
Simple shear wave velocity estimation for BE testing based on the minimal entropy of the signal as the arrival time of the shear wave in the noisy signal.

Why is it important?
It gives a reliable method to assess dynamic shear modulus of material thanks to Bender Element testing
Perspectives
It is a classic approach of detecting wave arrival time in seismology apply in geotechnical testing to detect shear wave arrival time. Its simplicity and its performance are quite interesting and could begin some procedure to detect automatically dynamic coefficient of soil or other material...
