Multiresolution finite element contrast source inversion method

2013 USNC-URSI Radio Science Meeting (Joint with AP-S Symposium), 2013
Electromagnetic inverse scattering problems are relevant to a broad range of applications, including biomedical imaging, subsurface prospecting and security monitoring, only to mention some examples. For such a reason, there is always a huge interest in developing effective inversion methods capable to provide reliable imaging results.

Adaptive finite element methods for nonlinear inverse problems

Proceedings of the 2009 ACM symposium on Applied Computing, 2009
Nonlinear inverse problems are usually formulated as optimization problems on function spaces constrained by partial differential equations. As a consequence, in realistic, three-dimensional cases, they become extraordinarily expensive to solve numerically, and advanced methods like adaptive mesh refinement become indispensible.

A deforming finite element method analysis of inverse Stefan problems

International Journal for Numerical Methods in Engineering, 1989
AbstractA deforming FEM (DFEM) analysis of one‐dimensional inverse Stefan problems is presented. Specifically, the problem of calculating the position and velocity of the moving interface from the temperature measurements of two or more sensors located inside the solid phase is addressed.

Apparent Young's modulus of human radius using inverse finite element method

Journal of Biomechanics, 2006
The ability to assess the elastic and failure properties of cortical bone at the radial diaphysis has a clinical importance. A new generation of quantitative ultrasound (QUS) devices and peripheral quantitative computed tomography (p-QCT) has been developed to assess non-invasively bone material and structural properties at the distal radius.

Modelling of single shot induction heating by inverse finite element method

International Journal for Numerical Methods in Fluids, 1995
AbstractThe induction heating model described herein couples the standard heat conduction equation with electro‐magnetic proximity‐skin equations. An Inverse Finite Element procedure, which is based on prior deterministic and probabilistic concepts, has been designed to solve the inherent inverse equation model with respect to the unknown coil current ...
