M. Dumont [1], R. Ernst [2], Y. Fautrelle [2], J. Etay [2]
[1] Emdpi Solutions-JAM, France
[2] Simap, France

Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and ... En savoir plus

A Concrete Arch Dam under Seismic Loading Conditions

A. Frigerio[1], G. Mazzà[1]
[1]RSE S.p.A., Milan, Italy

A new regulation for the safety assessment of dams has just been developed in Italy and its approval process is still in progress. As a matter of fact the behaviour of dams under seismic loading conditions is deemed of actual interest due to the recent seismic events occurred. In ... En savoir plus
