This paper presents a nondestructive method of brick wall dampness testing in real building structures. The setup was used to determine the moisture of test brick walls on the specially built laboratory models. The topological method and the gradient technique are used to optimization approach. The level set function was used to solve the inverse problem in the electrical impedance tomography. The...
Electrical impedance tomography (EIT) reconstructs the conductivity distribution of a domain using electrical data on its boundary. Shape derivatives and topological derivatives have been incorporated into level set methods to investigate shape optimization problems. The shape derivative measures the sensitivity of boundary perturbations while the topological derivative measures the sensitivity of...
This paper presents a nondestructive method of testing flood embankment dampness. We used a setup made of specially built laboratory models to determine the moisture level of flood embankments. The proposed algorithm was initialized by using one step methods and topological sensitivity analysis. We constructed the forward model and we solved the inverse problem in order to visualize moisture inside...
