Using Fatiando a Terra to solve inverse problems in geophysics

, 2014
Poster presented at Scipy 2014. The GitHub repository in the links contains: * Code used in the poster and to make the figures (in an IPython notebook); * SVG source of the poster (for Inkscape); Short description Inverse problems haunt the nightmares of geophysics graduate students. I'll demonstrate how to conquer them using Fatiando a Terra.

Stokes Equations in Geophysics: Forward and Inverse Problems

Motion of rock inside the Earth is commonly modeled by incompressible Stokes equations using various rheological models. Most models for the effective viscosity are characterized by severe nonlinearities and large viscosity jumps over small length scales as well as unknown or uncertain material properties, which lead to many theoretical and practical ...

Numerical treatment for inverse problems in applied Geophysics

, 2017
This thesis is concerned with numerical methods for inverse problems in applied Geophysics. Its main purpose is to reconstruct the electrical conductivity and the magnetic permeability of the soil by Electromagnetic induction (EMI). By taking measurements at several heights by a Ground Conductivity Meter (GCM), we can gain information about the depth ...

Methods for Underdetermined Inverse Problems in Astro- and Geophysics

Underdetermined inverse problems arise in many scientific fields, including gravitational wave (GW) astronomy and seismology. They are often formulated as optimization problems whose solution space is constrained using domain-specific prior knowledge. To solve these optimization problems efficiently, rapid and accurate methods are required to evaluate ...
