Macro-Kinematic Modelling of Continuous Deep Beams

, 2013
Cet article présente une approche macro-cinématique permettant de décrire les schémas de déformation avec fissures diagonales des poutres-voile continues. On montre comment une poutre continue formée de deux travées symétriques et supportant deux charges concentrées égales peut être modélisée à partir de seulement deux degrés de liberté.

Accelerating cavity fault prediction using deep learning at Jefferson Laboratory

Machine Learning: Science and Technology
Accelerating cavities are an integral part of the continuous electron beam accelerator facility (CEBAF) at Jefferson Laboratory. When any of the over 400 cavities in CEBAF experiences a fault, it disrupts beam delivery to experimental user halls. In this
