Abstract This study pertains to analysing the dynamical behaviour of a floating body undergoing parametric resonances. A simple vertical cylinder, representing classical spar-buoy, is considered, limiting its motion heave and pitch degrees freedom. Its geometry mass distribution are chosen such that 2:1 ratio pitch/roll natural frequency makes spar-buoy prone resonance. The system then studied ...

The purpose of this paper is to show an exemplary methodology for the integrated conceptioning of a floating wind turbine system with focus on the spar-type hull and the wind turbine blade-pitch-to-feather controller. It is a special interest to use a standard controller, which is easily implementable, even at early design stages. The optimization of the system is done with adapted static and d...

The Bibliothèque nationale de France has developed its trusted digital repository, SPAR (Scalable Preservation and Archiving Repository), as a data-first system. This implies having fully described collections, through use of metadata standards in the information packages, such as METS, PREMIS, MIX or textMD, in a way that will make sense given the diversity of our documents. The need for full ...
