Characterization of a phase camera for the Virgo gravitational wave detector

Gravitational waves predicted by Einstein have been measured in a few observatories worldwide. These detectors are complex interferometers with sizes of kilometers. Misalignments and aberrations in their optical set-up can create higher-order modes in the laser beam. These higher-order mode effects should be compensated to improve the...

Congestion management within and between the Dutch and German transmission networks

Electricity is an essential service that can be seen as a utility necessary for modern life. It is typically generated in large scale power plants, and must then be transported through a capital intensive infrastructure known as the transmission grid. It can not be easily stored for later use, which implies that supply and demand of it must be...
