Artificial intelligence based optimal coordination of directional overcurrent relay in distribution systems considering vehicle to grid technology

Ain Shams Engineering Journal
Optimal coordination of overcurrent relays has become a major challenge in power distribution systems due to the increasing participation of distributed generation (DG) and electric vehicle (EV) charging stations, especially vehicle-to-grid (V2G ...

Entropy flow in near-critical quantum circuits

, 2019
Near-critical quantum circuits are ideal physical systems for asymptotically large-scale quantum computers, because their low energy collective excitations evolve reversibly, effectively isolated from the environment.

Standard Model baryogenesis through four-fermion operators in braneworlds [PDF]

, 2001
We study a new baryogenesis scenario in a class of braneworld models with low fundamental scale, which typically have difficulty with baryogenesis. The scenario is characterized by its minimal nature: the field content is that of the Standard Model and ...
