Complementary Countermeasures for Detecting Scenic Face Spoofing Attacks

Sébastien Marcel, André Anjos

The face recognition community has finally started paying more attention to the long-neglected problem of spoofing attacks. The number of countermeasures is gradually increasing and fairly good results have been reported on the publicly available databases ...

Edge Localized Mode Control in TCV

Jonathan Rossel

The Tokamak concept, based on magnetic confinement of a hydrogen plasma, is one of today's most promising paths to energy production by nuclear fusion. The experimental scenarios leading to the largest fusion rate are based on a high confinement plasma reg ...

Development of a Global Version of the Gyrokinetic Microturbulence Code GENE

Laurent Villard, Stephan Brunner, Ben McMillan, Xavier Lapillonne

In order to address non-local effects in turbulent transport of magnetic-fusion devices, the gyrokinetic code GENE has been extended from a flux tube to a more global geometry. This global version of GENE includes radial variations of temperature and densi ...
