Investigation on Fault-ride Through Methods for VSC-HVDC Connected Offshore Wind Farms - Overview and New Proposal for Fault Ride Through

, 2015
Recently, there has been a fast development and deployment of wind energy to meet the increasing electrical power demand and to limit the use of fossil fuels. More and more wind farms are planned far from shore because of good wind condition and less visual impact. This is so called offshore wind farm (OWF).

Housing, Inequality and London

The Political Quarterly, EarlyView.
Abstract Regional inequalities are deeply entrenched in the UK. London, and its wider region, is often seen as the beneficiary of these inequalities. The capital houses a disproportionate share of the nation's population and its economic output. But London is also home to higher levels of inequality, poverty and child poverty than anywhere else in the ...

Closeness and disappointment in Jordanian friendships Proximité et déception en amitié en Jordanie

Journal of the Royal Anthropological Institute, EarlyView.
Western folk models of friendship assume that friends like one another, implying mutually positive feelings. However, accounts of friendship from across times and places suggest that disappointment goes along with friendship as often as mutual affection.

The role of the Eastern Mediterranean in human evolution: recent results from Greece Le rôle du Bassin méditerranéen oriental dans l’évolution humaine : résultats récents en Grèce

Journal of the Royal Anthropological Institute, EarlyView.
The Eastern Mediterranean lies directly on the principal migration route for human groups dispersing across Africa, Europe, and Asia. It also encompasses the Balkans, where fauna and flora, as well as hominin populations, are thought to have persisted through glacial periods.
