Presented signals correspond to the displacement of the string at 10 mm from the boundary x=L.
The string is initially plucked at its middle.
Details on the string properties and different configurations are given in the associated paper, which may be found at http://dx.doi.org/10.1016/j.jsv.2016.12.025.
