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

Electrical Resistance Tomography (ERT) applications to Chemical Engineering

Chemical Engineering Research and Design, 2013
Abstract Electrical Resistance Tomography (ERT) has the capability of offering time-evolving multidimensional comprehensive process knowledge, enrichment of fundamental process understanding and enhancement of the design and operation of process equipment by measuring the conductivity distribution within a process-plant of interest.

Electrical resistance tomography(ERT) by using an ECT sensor

2010 IEEE International Conference on Imaging Systems and Techniques, 2010
A sensor typically used in electrical capacitance tomography (ECT) was generalized to reconstruct the conductivity distribution in this paper. Analytical model was established for the sensor. As a result, the sensitivity matrix and the electric field lines can be obtained directly by using the formulae, which are fast and simple.

Fast reconstruction of electrical resistance tomography (ERT) images based on the projected CG method

Flow Measurement and Instrumentation, 2012
Abstract Electrical resistance tomography (ERT) is considered to be one of the most promising process tomography techniques for multi-phase flow measurement due to the advantages such as high speed, low cost and non-intrusive sensing. The image reconstruction for ERT is an inverse problem to find the conductivity distribution of an object by ...

Comparison of weathering properties by the help of Electrical Resistivity Tomography Technique (ERT)

2011
Weathering grades and their depths are some of the most important geo-engineering properties determining the cost, efficiency and sustainability of the engineering projects. Weathering properties of the rocks should be clearly defined during the preliminary surveys of the studies on foundations, slopes etc.
