The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... En savoir plus

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... En savoir plus

Current transfer from high-pressure arc plasmas to thermionic cathodes may occur in a diffuse mode, when the current is distributed over the front surface of the cathode, or in a spot mode, when most of the current is localized in one or more small areas. Spectra of perturbations of 3D ... En savoir plus

The scaling down of Copper interconnects is an effective approach to increasing the number of signal I/O lines and performance in advanced fine-pitch packaging. However, as dimensions are reduced, the risk of electromigration-induced failures in the copper interconnects becomes ... En savoir plus

Arc current welding is a widespread process in heavy industry for the assembly of metallic components. In order to ensure the good quality of assemblies welds, it is appropriate to master the welding process but also to have a deep understanding of interactions with the weld pool and ...

Slab dehydration and fluid migration in subduction zone is important because it allows us to understand characteristics of the arc volcanism such as migration of the volcano front as well as the global circulation of water and carbon. To minimize the technical difficulties in the ... En savoir plus

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts ... En savoir plus

The heat and fluid flow calculation inside the melt pool in welding processes is a complex challenge. It can be useful to predict defects in the weld seam or to study the influence of some process parameters. Even if the required equations are mastered over the last few years, the cost ...

In this paper a specific version of radiation collecting troughs is investigated. The trough arrangement has a shape which is a combination of a circular arc and adjacent parabolic curve pieces based on a paper by Tripanagnostopoulos [1]. An absorbing tube can be placed at varying ... En savoir plus

Plasma torches are used in processing of materials as well as in the energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be initiated by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the ... En savoir plus
