The integration of high voltage direct current (HVDC) grids into modern power systems has prompted extensive research into advanced power flow control techniques. These systems, renowned for their ...

A team of researchers in France has found that applying a voltage across a 100-nm-thick cylindrical soap film causes the fluid inside it to flow upwards. If the voltage is increased, the film thickens ...

Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...
