Application of Cesàro mean and the L-curve for the deconvolution problem

摘要: In this paper, the Cesaro mean technique is applied to regularize divergent problem which occurs in ground motion deconvolution analysis geotechnical engineering. To deal with ill-posed problem, we use corner of L-curve as compromise point determine optimal order so that high frequency content can be suppressed instead engineering judgement using concept a cutoff frequency. The fractional has been derived and used fulfill purpose. From examples shown, it found wave form including maximum acceleration accurately predicted both results avoided by proposed regularization technique.
