Abstract: Today high speed protection of power system elements is necessary and realizable. This paper introduces time-domain protection techniques for transmission lines using voltage and current ...

Why is Article 250 of the National Electrical Code (NEC), which covers the grounding and bonding of electrical systems, so often misunderstood? What exactly is the difference between grounding and ...

As all natural laws, Newtonian dynamics should be governed by Einstein’s Covariance Principle; i.e., being covariant under all coordinate transformations, even time-dependent transformations. But ...

Neuroscientists have discovered brain cells that form multiple coordinate systems to tell us "where we are" in a sequence of behaviors. These cells can play out different sequences of actions, just ...
