Finite-element contrast source inversion method for microwave imaging

Inverse Problems, 2010
With 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.

Inverse and Feedback Analyses Based on the Finite Element Method

2018
To undertake a successful computation task concerning the construction and operation process of hydraulic structures, one of the mostly concerned obstacles is the limited or incomplete sets of input data. This chapter presents the study on the inverse and feedback analyses for hydraulic structures using the FEM, intended to provide another parametric ...

Solving Inverse PDE by the Finite Element Method

2012
In this Master thesis project solving inverse PDE by the finite element method. An optimal control problems subjected to PDE constraint with boundary conditions is given. Construct the variational form then construct Lagrangian, which defined over whole space.

A Modified Inverse Eigensensitivity Method for Large Finite Element Models

2016
Finite element models should represent the dynamic behavior of real structures accurately to be subsequently used in design purposes. Therefore, finite element model updating methods have been developed in order to decrease the difference between analytical model and modal test results.
