A Multiresolution Analysis of Scattering by a Pair of Local Regions of Complex Heterogeneity

چکیده
The scattering by a pair of spatially disjoint local regions of complex (multiscale) stiiness heterogeneity in an unbounded thin linearly elastic plate, is investigated. Issues of the mutual interaction of the spatially disjoint scatterers and its manifestation within a homogenized, or eeective, formulation governing large scale response elds, are the focus. It is shown analytically and numerically that while one must incorporate scatterer/scatterer coupling for estimating the large scale response eld, one can neglect this coupling in estimating the eeective measures, for describing the scatterers.

Differentiation of active tumor from edematous regions of glioblastoma multiform tumor in diffusion MR images using heterogeneity analysis method
Background: Due to intrinsic heterogeneity of cellular distribution and density within diffusion weighted images (DWI) of glioblastoma multiform (GBM) tumors, differentiation of active tumor and peri-tumoral edema regions within these tumors is challenging. The aim of this paper was to take advantage of the differences among heterogeneity of active tumor and edematous regions within the gliobla...
متن کاملLink Prediction using Network Embedding based on Global Similarity
Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...
متن کاملAdopting the Multiresolution Wavelet Analysis in Radial Basis Functions to Solve the Perona-Malik Equation
Wavelets and radial basis functions (RBF) have ubiquitously proved very successful to solve different forms of partial differential equations (PDE) using shifted basis functions, and as with the other meshless methods, they have been extensively used in scattered data interpolation. The current paper proposes a framework that successfully reconciles RBF and adaptive wavelet method to solve the ...
متن کاملA Multiresolution Study of E ective Properties of Complex Electromagnetic Systems
A systematic study of the across scale coupling phenomenology in EM scattering problems is addressed using the theory of multiresolution decomposition and orthogonal wavelets. By projecting an integral equation formulation of the scattering problem onto a set of subspaces that constitutes a multiresolution decomposition of L 2 (R), one can derive two coupled formulations. The rst governs the ma...
