Carbon mapping in steel using 12C(d,pγ)13C in external beam

Carbon concentration and distribution has a dramatic impact on mechanical properties of steel. The manufacture technology of ancient steel is an important question in archaeometallurgy, especially during medieval times when the production process…

New model of crack propagation of aluminium wire bonds in IGBT power modules under low temperature variations

In this paper, a new model of lifetime prediction for wirebond degradation during power cycling in IGBT power module is proposed. This model is based on experimental crack propagation analyses and on a plastic strain empirical law. For the…

Effect of 16 O 6+ ion-irradiation on structural, magnetic properties and antistructural modeling of Zn-nanoferrites

XRD analysis and magnetic measurements were used to study the effect of 80 MeV 16 O 6þ ion-irradiation on structural, magnetic properties, and anti-structural modeling of as-burnt ZnFe 2 O 4 synthesized by sol-gel auto-combustion technique. XRD…

History of magnetism

Magnetism is a science with more than two millennia of recorded history. The attraction of ferrous objects to a permanent magnet across a distance has been a source of curiosity since the iron age. Investigations of magnetic phenomena led to the…

Renforcement de la localisation piétonne par détection visuelle via des informations géométriques et spatiales contenues dans une carte

This paper presents a technique to reinforce a proprioceptive system of indoor pedestrian location, assisted by a camera,embedded in a phone. A YOLOv5 neural network is trained to detect landmarks present in the images. The main contributionof this…
