From Survey to Rescue Excavation: Ground Truthing Geophysical Data From the Timișoara‐Freidorf La Tène Culture Settlement

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT The current study employs a geophysical approach, integrating magnetic and Electrical Resistivity Tomography techniques, to unveil the Timișoara‐Freidorf La Tène culture settlement in the lowlands of the Banat region, southwestern Romania, within the context of a rescue excavation.

Multidisciplinary Approach to Identifying Early Mediaeval Gates: A Case Study of the Břeclav–Pohansko Stronghold

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This study presents a comprehensive approach to verifying a presumed western gate at Pohansko by integrating nondestructive geophysical methods (ERT, magnetometry and core prospection) with traditional archaeological excavation. The identification and characterization of gates by nondestructive methods within early mediaeval fortified sites ...

Eigenvector of gravity gradient tensor for estimating fault dips considering fault type

open access: yesProgress in Earth and Planetary Science, 2017
The dips of boundaries in faults and caldera walls play an important role in understanding their formation mechanisms. The fault dip is a particularly important parameter in numerical simulations for hazard map creation as the fault dip affects ...

From Cosmic Explosions to Terrestrial Fires?: A Reply [PDF]

open access: yesarXiv, 2020
Deschamps and Mottez (hereafter DM) argue that the Gauss-Matuyama terrestrial magnetic field reversal may have left a vanishing main dipole moment to the field for a time of order 10,000 years. They say this may have allowed an enhanced cosmic ray flux, boosting the effect we proposed in Melott and Thomas (2019).

Connecting the Dots: A Comprehensive Literature Review on Low and Medium-Voltage Cables, Fault Types, and Digital Signal Processing Techniques for Fault Location [PDF]

open access: yesarXiv, 2023
The review begins with an exploration of acceptable cable types guided by local standards. It then investigates typical cable faults, including insulation degradation, conductor faults, and ground faults, providing insights into their characteristics, causes, and detection methods.

Three‐Dimensional Electrical Resistivity Tomography Schemes Optimized for Imaging Wall Foundations

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper describes the application of three‐dimensional electrical resistivity tomography (ERT) in urban environments to detect wall foundations or similar structures. In this study, a specific measurement strategy based on optimized 3D measurement arrays with surface electrodes is proposed and tested.

Permeability evolution during progressive development of deformation bands in porous sandstones [PDF]

open access: yes, 2003
[1] Triaxial deformation experiments were carried out on large (0.1 m) diameter cores of a porous sandstone in order to investigate the evolution of bulk sample permeability as a function of axial strain and effective confining pressure.
