Regularization Methods for Nonlinear Ill-Posed Problems with Applications to Phase Reconstruction,e.g. parameter identification from boundary measurements (see e.g. [36]), inverse scattering (see e.g. [12], [13], [14]), or phase reconstruction (see e.g. [40]). The mathematical formulation of inverse problems usually gives rise to ill-posed problems in Hadamard’s sense, where especially the lack 作者: 態(tài)度暖昧 時間: 2025-3-22 04:39
Qualitative Methods in Inverse Scattering Theory,lving the inverse scattering problem that arises in such applications. This is due to the fact that in order to achieve satisfactory resolution and sufficient penetration of the wave into the material it is often necessary to use frequencies in the resonance region. In this case the inverse scatteri作者: 侵略主義 時間: 2025-3-22 11:26 作者: 遺忘 時間: 2025-3-22 13:00
