A new approach to quantify the reliability of Electrical Resistivity Tomography (ERT) images

2023
Anthropogenic and natural hazards assessments need a good knowledge of the structures. A classical approach based on geological observations or soil mechanics investigations is often insufficient to characterize both the structures and the nature of subsurface materials.

Interrogation of a precipitation reaction by electrical resistance tomography (ERT)

AIChE Journal, 2005
AbstractElectrical resistance tomography (ERT) provides a noninvasive and nonintrusive technique for the full 3‐D interrogation of a typical stirred vessel reactor up to a spatial discrimination of approximately 2,500 derived data points. Some recent ERT results are presented for a newly refurbished 8 ring 16‐sensor 2.3 m3 pilot scale vessel, detecting
