To protect spillways against cavitation damage, adding a small air concentration to the flow close to the invert is efficient. Aerator performance on smooth chutes was therefore well studied in terms of air entrainment and downstream air concentration deve ...

Sudden starting and stopping of turbines and pumps lead to highly unsteady flow in tailrace channels of hydropower plants (HPP). Submergence of Pelton turbines and air entrainment in pumps due to surge waves must be avoided by technical measures. The exist ...

The mouth of the Baye de Clarens torrent in Switzerland is currently constrained by lateral training walls, sequent sills and a bridge with a low hydraulic capacity. Due to a bed load trap upstream, few sediments reach the mouth. To improve flood protectio ...

This paper discusses the advantages of subthreshold logic for True Random Number Generators (TRNG). In this work, the entropy is modeled, and a lower bound of Shannon's entropy per output bit can quickly be estimated. Thanks to this model, sizing TRNGs in ...

Le réchauffement climatique est une réalité alarmante et conduit probablement à une augmentation de la pression sur les systèmes socio‑économiques. Cependant, dans les régions de haute‑montagne, il pourrait induire l’opportunité d’adapter des aménagements ...
