Deep Learning Inversion of Electrical Resistivity Data [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2019
The inverse problem of electrical resistivity surveys (ERSs) is difficult because of its nonlinear and ill-posed nature. For this task, traditional linear inversion methods still face challenges such as suboptimal approximation and initial model ...

Preliminary study on the contribution of osmotic effects for the electrical resistivity of sands [PDF]

open access: yesE3S Web of Conferences, 2020
Electrical resistivity of soils can be used to evaluate the level of contamination in soils in geophysical prospection tests. The chemical composition of pore fluid also corresponds to a given water potential, named as osmotic suction.

Investigation of the early-age microstructural development of hydrating cement pastes through electrical resistivity measurements

open access: yesCase Studies in Construction Materials, 2020
The non-contact electrical resistivity method was employed to investigate the microstructural development of three grades of cement under a fixed water-to-cement ratio (w/c) and the same curing conditions. The method was verified by measuring the heat of
