How does seismic anisotropy evolve as a function of mineralogical and textural changes across ductile shear zones? – an experimental and modelling approach

Strain localization and the development of ductile shear zones in the middle and lower crust play major roles in lithosphere dynamics. Geophysical imaging of ductile shear zones is an issue for ore geology, for the understanding of the lithosphere rheology ...

An iterative particle filter approach for coupled hydro-geophysical inversion of a controlled infiltration experiment

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

The modeling of unsaturated groundwater flow is affected by a high degree of uncertainty related to both measurement and model errors. Geophysical methods such as Electrical Resistivity Tomography (ERT) can provide useful indirect information on the hydrol ...

Coupled inverse modeling of a controlled irrigation experiment using multiple hydro-geophysical data

Gabriele Manoli, Damiano Pasetto, Matteo Rossi

Geophysical surveys can provide useful, albeit indirect, information on vadose zone processes. However, the ability to provide a quantitative description of the subsurface hydrological phenomena requires to fully integrate geophysical data into hydrologica ...

Lightning Electromagnetic Fields and Their Induced Currents on Buried Cables. Part II: The Effect of a Horizontally Stratified Ground

Mario Paolone, Keyhan Sheshyekani

We use a finite element method (FEM) to evaluate the effect of a horizontally stratified two-layer ground on underground lightning electromagnetic fields and their induced currents on the shield of buried cables. It is shown that the azimuthal component of ...

Direct localised measurement of electrical resistivity profile in rat and embryonic chick retinas using a microprobe

Philippe Renaud, Arnaud Bertsch, Harald Van Lintel, Robert Meissner, Sri Harsha Kasi Raj

We report an alternative technique to perform a direct and local measurement of electrical resistivities in a layered retinal tissue. Information on resistivity changes along the depth in a retina is important for modelling retinal stimulation by retinal p ...

Axisymetrical infiltration in soil imaged by non-invasive electrical resistivimetry

Jordi Batlle-Aguilar

To progress in the monitoring and understanding of soil water processes, geophysical methods can be helpful because they are non invasive and as such do not disturb either the structure or the water dynamics of the soil. In this study we attempt to image w ...

Cu grain growth in damascene narrow trenches

Cyril Cayron

Since the end of the last century, Cu damascene integration scheme has been the favoured choice for advanced interconnect technologies. Indeed, due to the lowest Cu bulk resistivity and to it higher resistance to electromigration, performances enhancement ...

Three-dimensional petrographical investigations on borehole rock samples: a comparison between X-ray Computed- and Neutron Tomography

Aurèle Parriaux, Pascal Turberg, Pierre Guillaume Christe

Technical difficulties associated with excavation works in tectonized geological settings are frequent. They comprise instantaneous and/or delayed convergence, sudden collapse of gallery roof and/or walls, outpouring of fault-filling materials and water in ...

Axysimetrical water infiltration in soil imaged by non-invasive electrical resistivimetry

Jordi Batlle-Aguilar

Axisymetrical infiltration of water in soil has been largely studied since the development of tension disc infiltrometers. Procedures have been developed to derive the hydraulic properties of soils from axisymetrical infiltration measurements but rely on s ...
