Optimization of impulse resistance reduction for tower grounding device of transmission line
Journal of Physics: Conference Series, 2020 Abstract When the lightning strikes the tower, the lightning current is discharged into the ground through the tower grounding device. The magnitude of the impulse earthed resistance of the tower grounding device determines the lightning discharge capacity of the tower. Therefore, the tower grounding device directly affects the lightning

Interests without History: Some Difficulties for a Negative Aristotelianism [PDF]
, 2017 This paper focuses on 3 features of Freyenhagen's Aristotelian version of Adorno. (a) It challenges the strict negativism Freyenhagen finds in Adorno. If we have morally relevant interests in ourselves, it is implicit that we have a standard by which to ...
