Sensitivity analysis of fracture scattering

Sensitivity analysis of fracture scattering

The way fractures affect seismic waves depends on fracture mechanical parameters, such as compliance and saturating fluid, and on their geometric properties, such as dimensions and spacing. When fractures are small relative to the seismic wavelength, waves will be weakly affected by fractures, and in effective medium theory, a zone comprised of many small fractures is equivalent to a homogeneou...

Domain Sensitivity Analysis for Acoustic Scattering Problems

We consider scattering problems described by the Dirichlet boundary value problem for the scalar Helmholtz equation in exterior domains := IR 2 n i : Such problems include the scattering of acoustic waves from a sound-soft obstacle or the scattering of electromagnetic waves from perfectly conducting cylinders. The paper concerns with the characterization of the G^ ateaux derivative of the far-e...

Sensitivity Analysis of MPSIAC Model

MPSIAC is currently known as an appropriate method to measure sediment ofWatershed basins of the country while there has not been any sensitivity analysis so far forthis method. In this study, required data for MPSIAC model were gathered from six basins;Amame-Kamarkhani, Kand-Golandok, Tang Kenesht (from two different references), Nojian(from three different references), Pegahe sorkh katvand (f...

Sensitivity Analysis of the Scattering-Based SARBM3D Despeckling Algorithm

Synthetic Aperture Radar (SAR) imagery greatly suffers from multiplicative speckle noise, typical of coherent image acquisition sensors, such as SAR systems. Therefore, a proper and accurate despeckling preprocessing step is almost mandatory to aid the interpretation and processing of SAR data by human users and computer algorithms, respectively. Very recently, a scattering-oriented version of ...
