In many situations across computational science and engineering, multiple computational
models are available that describe a system of interest. These different models have varying …

Electrical resistance tomography imaging of concrete

K Karhunen, A Seppänen, A Lehikoinen… - Cement and concrete …, 2010 - Elsevier
We apply Electrical Resistance Tomography (ERT) for three dimensional imaging of
concrete. In ERT, alternating currents are injected into the target using an array of electrodes …

Compensation of modelling errors due to unknown domain boundary in electrical impedance tomography

A Nissinen, VP Kolehmainen… - IEEE transactions on …, 2010 - ieeexplore.ieee.org
Electrical impedance tomography is a highly unstable problem with respect to measurement
and modeling errors. This instability is especially severe when absolute imaging is …

The Bayesian approximation error approach for electrical impedance tomography—experimental results

A Nissinen, LM Heikkinen… - Measurement Science and …, 2007 - iopscience.iop.org
Inverse problems can be characterized as problems that tolerate measurement and
