Forward and inverse modeling for jovian seismology

Surface Wave Scattering Theory with Applications to Forward and Inverse Problems in Seismology

Recently, a formalism for three-dimensional sur­face-wave scatlering in a plane geometry was derived. Sincetelescismic surface-wave data arc generally recorded at epi­central distances large enough to be innuenced by the sphe­ricity of the Earth, it is necessary to find the eITects of aspherical geometry on surface-wave sealtering. The theoryof surface-wavc scattering re...

Molecular seismology: an inverse problem in nanobiology.

The density profile of an elastic fiber like DNA will change in space and time as ligands associate with it. This observation affords a new direction in single molecule studies provided that density profiles can be measured in space and time. In fact, this is precisely the objective of seismology, where the mathematics of inverse problems have been employed with success. We argue that inverse p...

Basin Structure Estimation by Waveform Modeling: Forward and Inverse Methods

We introduce a technique for using broadband seismograms recorded from earthquakes at local and regional distances to refine basin structure. For the region outside the basin, we assume a one-dimensional (1D) crustal model and analytical techniques (GRT) to propagate the energy from sources to the basin edge where the motions are then interfaced with a (2D) finite-difference algorithm (Wen and ...

global results on some nonlinear partial differential equations for direct and inverse problems

در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
