Electrical Tree Initiation Properties in Cross-Linked Polyethylene Under DC-Impulse Composite Voltages

IEEE Access, 2018
DC cables may be subjected to impulse overvoltage during operation, which may cause electrical tree inside the cable insulation. So, it is necessary to investigate the influence of impulse voltage on the insulation of dc cable.

Evaluating the Impact of Transmission Power on Selecting Tall Vehicles as Best Next Communication Hop [PDF]

, 2012
The relatively low height of antennas on communicating vehicles in Vehicular Ad Hoc Networks (VANETs) makes one hop and as well multi-hop Vehicle-to-Vehicle (V2V) communication susceptible to obstruction by other vehicles on the road.
