Smart Water Meter Using Electrical Resistance Tomography [PDF]
Smart flow monitoring is critical for sewer system management. Obstructions and restrictions to flow in discharge pipes are common and costly. We propose the use of electrical resistance tomography modality for the task of smart wastewater metering. This paper presents the electronics hardware design and bespoke signal processing to create an embedded ...

Determination of cavities using electrical resistivity tomography
Geophysical surveys for cavity detection are one of the most common nearsurface applications. The usage of resistivity methods is also very straightforward for the air-filled underground voids, which should have theoretically infinite resistivity in the ...

Cone-based electrical resistivity tomography [PDF]
Abstract Determining the 3D spatial distribution of subsurface properties is a challenging, but critical, part of managing the cleanup of contaminated sites. We have developed a minimally invasive technology that can provide information about the 3D distribution of electrical conductivity.

A convolutional neural network approach to electrical resistivity tomography
Abstract Electrical resistivity tomography (ERT) is an ill-posed and non-linear inverse problem commonly solved through deterministic gradient-based methods. These algorithms guarantee fast convergence toward the final solution but hinder accurate uncertainty assessments. On the contrary, numerical Markov Chain Monte Carlo algorithms provide
