Exponentially‐constrained Gaussian mixture model for quantifying vertical development of water‐conducting fracture zones in lithologically stratified mining roofs

Deep Underground Science and Engineering, EarlyView.
This study proposes an exponentially‐constrained Gaussian mixture model (EcGMM) to quantify vertical fracture heterogeneity in stratified roof strata. The model integrates a piecewise exponential decay term capturing global stress dissipation with Gaussian components representing localized fracture intensification at lithological interfaces.

Characterization of the mixing of wheat straw slurries through electrical resistance tomography (ERT) [PDF]

, 2023
Wheat straw is a good source for the production of bioethanol. It can be converted into smaller fibers using mechanical treatment such as milling and grinding. These fibers can then be suspended in water and the slurry behaves as a non-Newtonian fluid possessing yield stress. In mixing operations, the presence of yield stress creates a region of active

Recovery from electrode position uncertainties in geophysical electrical resistance tomography – Application to moisture transport imaging

Near Surface Geophysics, EarlyView.
Abstract In studies of subsurface hydrology, monitoring and imaging techniques are used to estimate the moisture content, or to track moisture or injected tracer movement. One applied imaging technique is electrical resistance tomography (ERT), in which measurements collected using electrodes placed on the ground surface or in boreholes are used to ...

Geophysical investigation at Sainte‐Marguerite‐sur‐Mer (Normandy, France): From a supposed landfill to a forgotten military network?

Near Surface Geophysics, EarlyView.
Abstract This study focuses on characterising a strong and unexpected anomaly observed during an electromagnetic induction (EMI) survey conducted on the chalk cliff plateau at Sainte‐Marguerite‐sur‐Mer, in the Normandy region, France. The site was selected for a long‐term study of chalk cliff coastal erosion that began in 2017 and has been studied for ...
