Accurate position estimation methods based on electrical impedance tomography measurements
Vergara, Samuel; Sbarbaro, Daniel; Johansen, Tor Arne (Journal article; Peer reviewed, 2017)Electrical impedance tomography (EIT) is a technology that estimates the electrical properties of a body or a cross section. Its main advantages are its non-invasiveness, low cost and operation free of radiation. The ... -
Adaptive Kalman filter for on-line spectroscopic sensor corrections
Sbarbaro, Daniel; Johansen, Tor Arne; Yanez, JP (Peer reviewed; Journal article, 2023)Spectroscopic sensors provide online information about the composition and concentration of species in a sample by analyzing the interaction of light and matter. At the industrial scale, external variables such as temperature, ... -
On-line calibration of spectroscopic sensors based on nonlinear observers
Sbarbaro, Daniel; Johansen, Tor Arne (Peer reviewed; Journal article, 2020)Spectroscopic sensors provide on-line information about process variables and they have been widely used for monitoring and control. These sensors measure the spectral responses at a large number of wavelengths correlated ... -
State estimation and inverse problems in Electrical Impedance Tomography: observability, convergence and regularization
Sbarbaro, Daniel; Vauhkonen, M; Johansen, Tor Arne (Journal article; Peer reviewed, 2015)Solving electrical impedance tomography (EIT) inverse problems in real-time is a challenging task due to their dimension, the nonlinearities involved and the fact that they are ill-posed. Thus, efficient algorithms are ...
