The characterization of sabkhas in the Eastern parts of Saudi Arabia and its implications for engineering.

, 1996
PhDThe sabkhas of the Eastern Province of Saudi Arabia, some coastal some well inland, exhibit variation in clastic fraction, evaporite type, and brine composition. The clastic fraction largely reflects the local host lithologies with carbonate tending

Effects of double ground faults in Wind Farms collector cables

, 2015
Medium Voltage collector cables of Wind Farms have metal shields connected to the grounding systems of the towers and of the connection station. Thanks to this bonding, when a ground fault occurs, the fault current splits itself among all the grounding ...

Application of Ground-Air Heat Exchanger to Reduce Cooling Energy Demand of Low-Rise Office Building in Southeast of UK

, 2008
The use of ground-air heat exchangers (GAHX) in a ventilation system is gaining recognition as a low or zero carbon ventilation strategy. However, there is very limited research and published data on the thermal performance of GAHX under UK climate. This
