In the future, Europe is to be dominantly powered by renewable energy. The expansion of wind and solar power capacity and the provision of sufficient power in winter are just two of the challenges ...

For a long time, the "heart" of the direct current transmission projects—thyristor-based converter valves—has faced persistent challenges of "commutation failure" caused by the disturbances in ...

Abstract: The direct current resistivity method is a primary technique for detecting water-bearing structures ahead of tunnel and coal mine excavation faces. We propose a dipole array advance ...
