The paper describes the preliminary studies of University of Minho on the use of Electric Impedance/Resistance Tomography to assess masonry structures. The study is focused on the analysis of values of current and voltage ...

Electrical Impedance Tomography (EIT) is a non– invasive method that can be used to estimate the electrical conductivity of the head tissues. It is based on the measurement of electric potential on the scalp generated by ...

Chaotic urban expansion often leads to hazardous environmental consequences. The absense of rainwater outflow management, coupled with low cohesion in some terrains is a geotechnical threat for the population since it may ...

In this paper we show a simple and versatile computational simulation method for determining electric currents and electric potential in 2D and 3D media with arbitrary distribution of resistivity. One of the highlights of ...

The results of geophysical prospections in an archaeological site of hispanic type in Panama (Central America) are presented in this article. The archaeological site of Old Panama has been intensively investigated with the ...

The topic of this work are two further developments of the Factorization method for electrical impedance tomography.We present a modification of this method that is capable of detecting mixed inclusions, i.e. both inclusions ...
