Derivative-Free Iterative One-Step Reconstruction for Multispectral CT

Journal of Imaging
Image reconstruction in multispectral computed tomography (MSCT) requires solving a challenging nonlinear inverse problem, commonly tackled via iterative optimization algorithms.

On reconstructing an unknown coordinate of a nonlinear system of differential equations [PDF]

Opuscula Mathematica, 2014
The paper discusses a method of auxiliary controlled models and the application of this method to solving problems of dynamical reconstruction of an unknown coordinate in a nonlinear system of differential equations.

Inverse problems in diffraction [PDF]

A two-dimensional problem of diffraction of a plane electromagnetic wave on a smooth 2 pi-periodic surface is considered. A numerical algorithm solving this problem is developed.

Feynman's Inverse Problem

SIAM Review
We analyse an inverse problem for water waves posed by Richard Feynman in the BBC documentary Fun to Imagine. The problem can be modelled as an inverse Cauchy problem for gravity-capillary waves on a bounded domain. We do a detailed analysis of the Cauchy problem and give a uniqueness proof for the inverse problem.

Inverse Scattering in a Multipath Environment

Advanced Electromagnetics, 2016
In this contribution an inverse scattering problem is ad- dressed in a multipath environment. In particular, multipath is created by known ”extra” point-like scatterers (passive elements) expressely deployed between the scene under in- vestigation and ...

Evolutionary Multi-Agent Computing In Inverse Problems

Computer Science, 2013
The paper tackles the application of evolutionary multi-agent computing to solving inverse problems. High costs of fitness function call become a major difficulty when approachingthese problems with population-based heuristics, however evolutionary agent-

Some non-standard statements of inverse problems

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Modelûvannâ, 2010
We study the inverse problems which can not be solved in the classical framework: Krylov inverse problem, early diagnostics of a rotor unbalance, the most probable so­lution.
