Adaptive finite element methods for nonlinear inverse problems
Proceedings of the 2009 ACM symposium on Applied Computing, 2009Nonlinear 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, 1989AbstractA 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, 2006The 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, 1995AbstractThe 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 ...

An inverse finite element method for pricing American options
Journal of Economic Dynamics and Control, 2013Abstract The pricing of American options has been widely acknowledged as “a much more intriguing” problem in financial engineering. In this paper, a “convergency-proved” IFE (inverse finite element) approach is introduced to the field of financial engineering to price American options for the first time. Without involving any linearization process at

Finite Element Methods for Solving Parabolic Inverse Problems
2000In this paper, we apply the finite element method to identify physical parameters in parabolic initial-boundary value problems. The identifying problem is formulated as a constrained minimization of the L 2-norm error between the observation data and the physical solution to the original system, with the H 1-regularization or BV-regularization.

Finite-element contrast source inversion method for microwave imaging
Inverse Problems, 2010With respect to the microwave imaging of the dielectric properties in an imaging region, the full derivation of a new inversion algorithm based on the contrast source inversion (CSI) algorithm and a finite-element method (FEM) discretization of the Helmholtz differential operator formulation for the scattered electromagnetic field is presented.
