Reconstruction of discontinuities in systems
We survey some recent results on the reconstruction of discontinuities by boundary measurements for elasticity and related systems in two dimensions. Our main tool is a new type of complex geometrical optics solutions.
متن کاملAutomatically Localizing Discontinuities during Surface Reconstruction
This paper describes an extension to a class of surface reconstruction algorithms based on the minimization of variation of curvature, the so-called curvature consistency framework. It deals explicitly with the problem of localizing surface discontinuities, which was one of the shortcomings of the original work. Inter-pixel interactions during the variational relaxation based smoothing process ...
متن کاملReconstruction of discontinuities from backscattering data in 2 D ∗
We prove that the non smooth part of a non compactly supported potential q in the Schrödinger Hamiltonian −∆ + q, in dimension n = 2, is contained in its Born approximation qB for backscattering data in a precise sense in terms of continuity: Given q in W the difference q−qB is in the Hölder class Λ for any β < α.
متن کاملComplex Geometrical Optics Solutions and Reconstruction of Discontinuities
In this paper we provide a framework for constructing general complex geometrical optics solutions for several systems of two variables that can be reduced to a system with the Laplacian as the leading order term. We apply these special solutions to the problem of reconstructing inclusions inside of a domain filled with known conductivity from local boundary measurements. Computational results ...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
