... the estimated UIR via the regularization-based method from different time duration (3 and 1 s) as well as different sampling rate (250 and 500 Hz), with data number 3 × 250, 1 × 250, and 1 × 500, respectively. The estimation of the UIR function is, in essence, an inverse problem with the solution of the ill...

...Lu Sun; Feiquan Luo; Wenjun Gu A rigorous theoretical foundation for solving elastodynamic inverse problem of multilayered media under an impulse load is established in this paper. The inversion is built upon the forward dynamic analysis of multilayered elastic media using transfer matrix approach...
