Multi‐scale electrical resistivity imaging and long‐term monitoring as a tool for groundwater management

open access: yesNear Surface Geophysics, EarlyView.
Abstract Extensive pumping, storm floods or sea‐level rise can lead to regional and local‐scale processes of saltwater intrusion into coastal aquifers. Particularly when exacerbated by the impacts of climate change, these processes can threaten freshwater resources and thus drinking water supplies and need to be prevented by investigation and ...

Multi‐scale geophysical imaging of neotectonic fault activity in the northern Upper Rhine Graben, Germany

open access: yesNear Surface Geophysics, EarlyView.
Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data

A Method for Target Detection Based on Mmw Radar and Vision Fusion [PDF]

open access: yesarXiv
An efficient and accurate traffic monitoring system often takes advantages of multi-sensor detection to ensure the safety of urban traffic, promoting the accuracy and robustness of target detection and tracking. A method for target detection using Radar-Vision Fusion Path Aggregation Fully Convolutional One-Stage Network (RV-PAFCOS) is proposed in this
