In high latitude regions, the moisture dynamics in road systems is more complicated due to freezing/thawing. A better understanding of moisture dynamics in road systems in cold regions is essential for a stable road structure design and also for a sustainable road hydrologic environment. ... En savoir plus
The Geoenvironmental Engineering Group of the University of Castilla-La Mancha is developing a computational tool, M4B, for describing the influence of environmental loads on the deformation behavior of soils and its interaction with building foundations. This tool comprises a set of ... En savoir plus
We have developed a small environmental chamber to expose a sample to adjustable climate conditions. This climate chamber will be used as sample environment for small-angle neutron scattering (SANS) experiments. SANS is a favorable measuring method, to explore structural changes on the ...

The loaded underground high voltage cable generates magnetic field with industrial frequency. Depending on the current rating and cable allocation, the magnetic exposure to public area may exceed the requested limit from customer. Extra shielding should then be applied. A primary FEM ...

Radiofrequency ablation is one of the common methods used to treat pain, movement or mood disorders. It bases on the electromagnetic energy provided to the selected tissue when an alternating current is applied. The resistive heating produced in this process provokes temperature rise in ...

Acceleration is an important quantity to be measured in high-speed dynamics. A new piezoresistive sensor for the measurement of high-amplitude, short-duration transient accelerations of up to 100,000 g has been developed at the Fraunhofer EMI. Its figure of merit (sensitivity x resonance ... En savoir plus
In addition to using advanced functions built-into the engine of the COMSOL Multiphysics® software, we integrate dynamic properties of rotating components that are measured or pre-computed. Here, it is shown how to integrate fluid-film characteristics and take advantage of post ... En savoir plus
The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... En savoir plus
Crystallization phenomena are of first interest in several industrial applications (polymer forming processes, metallurgy, phase change flow, energy storage...). A classical way to model the crystallization evolution is using the Nakamura kinetics law. In this paper, a novel physics ... En savoir plus
High power CO2 lasers have been the workhorses for sheet metal cutting, welding and many more applications in materials processing during the past decades. Even though a significant replacement by fiber coupled lasers takes place, there are still many applications that benefit from the ... En savoir plus
