All-graphene edge contacts: Electrical resistance of graphene T-junctions [PDF]

, 2016
Using ab-initio methods we investigate the possibility of three-terminal graphene "T-junction" devices and show that these all-graphene edge contacts are energetically feasible when the 1D interface itself is free from foreign atoms.

Wide-Area Damping Controller of FACTS Devices for Inter-Area Oscillations Considering Communication Time Delays [PDF]

, 2014
The usage of remote signals obtained from a wide-area measurement system (WAMS) introduces time delays to a wide-area damping controller (WADC), which would degrade system damping and even cause system instability. The time-delay margin is defined as the
