Learning-based approaches for reconstructions with inexact operators in nanoCT applications
Tom Lütjen, Fabian Schönfeld, Alice Oberacker +4
Imaging problems such as the one in nanoCT require the solution of an inverse problem, where it is often taken for granted that the forward operator, i.e., the underlying physical…
On numerical aspects of parameter identification for the Landau-Lifshitz-Gilbert equation in Magnetic Particle Imaging
Tram Thi Ngoc Nguyen, Anne Wald
The Landau-Lifshitz-Gilbert equation yields a mathematical model to describe the evolution of the magnetization of a magnetic material, particularly in response to an external appl…
A method for determining the parameters in a rheological model for viscoelastic materials by minimizing Tikhonov functionals
Rebecca Rothermel, Wladimir Panfilenko, Prateek Sharma +4
Mathematical models describing the behavior of viscoelastic materials are often based on evolution equations that measure the change in stress depending on its material parameters…
On parameter identification problems for elliptic boundary value problems in divergence form, Part I: An abstract framework
Heiko Hoffmann, Anne Wald
Parameter identification problems for partial differential equations are an important subclass of inverse problems. The parameter-to-state map, which maps the parameter of interest…
Sequential subspace optimization for recovering stored energy functions in hyperelastic materials from time-dependent data
Rebecca Klein, Thomas Schuster, Anne Wald
Monitoring structures of elastic materials for defect detection by means of ultrasound waves (Structural Health Monitoring, SHM) demands for an efficient computation of parameters…
