<p style='text-indent:20px;'>This paper is concerned with the inverse problem of time-harmonic acoustic scattering by an unbounded, locally rough interface which assumed to be a local perturbation plane. The purpose this recover from near-field measurement given on straight line segment finite distance above and generated point sources. Precisely, we propose novel version linear sampling ...

Inverse problems are more challenging when only partial data available in general. In this paper, we propose a two-step approach combining the extended sampling method and ensemble Kalman filter to reconstruct an elastic rigid obstacle using data. first step, approximate location of unknown is obtained by method. second employed shape. The step guides construction initial particles filter, whic...

Recently there has been increasing interest in species sampling priors, the nonparametric priors defined as the directing random probability measures of the species sampling sequences. In this paper, we show that not all of the species sampling priors produce consistent posteriors. In particular, in the class of Pitman-Yor process priors, the only priors rendering posterior consistency are esse...

<p style='text-indent:20px;'>Consider the two-dimensional inverse elastic wave scattering by an infinite rough surface with a Dirichlet boundary condition. A non-iterative sampling method is proposed for detecting taking field measurements on bounded line segment above surface, based reconstructing modified near-field equation associated special which generalized our previous work Helmhol...
