Inverse analysis with integral transformed temperature fields: Identification of thermophysical properties in heterogeneous media
TL;DR: In this paper, the authors introduce the use of integral transformed temperature measured data for the solution of inverse heat transfer problems, instead of the common local transient temperature measurements, which is capable of significantly compressing the measured data through the integral transformation, without losing the information contained in the measurements and required for the inverse problem.

Simultaneous estimation of spatially distributed thermal conductivity, heat capacity and surface heat transfer coefficient in thermal tomography
Jussi Toivanen,Ville Kolehmainen,Tanja Tarvainen,Tanja Tarvainen,Helcio R. B. Orlande,Jari P. Kaipio,Jari P. Kaipio +6 more
TL;DR: In this paper, Kolehmainen et al. extend the computational methods of thermal tomography to the more practical setup of imaging targets, where the boundary heat flux from the target to the surrounding medium is not known.

Thermal Tomographic Detection of Inhomogeneities
TL;DR: In this paper, the authors investigated the use of both a linearization and regularization technique and a randomized search procedure based on a genetic algorithm to invert a set of equations that relate the conductivity of a medium to temperature measurements on the surface of the medium.

Experimental Identification of Thermophysical Properties in Heterogeneous Materials with Integral Transformation of Temperature Measurements from Infrared Thermography
TL;DR: In this article, the experimental estimation of spatially variable thermal conductivity and diffusivity in heterogeneous media, with temperature measurements obtained via infrared thermography being used in the inverse analysis, is performed on the transformed experimental temperature field instead of employing the actual local temperature measurements.
