The electrical resistance between the running surfaces of the opposite wheels of a wheelset does not exceed 0,05 Ohm, measured by a voltage between 1,8 VDC and 2,0 VDC (open circuit).

Greater energy efficiency is achieved in comparison with the open cycle gas turbine plants and steam cycle plants (using heavy fuel oil or natural gas) currently used for baseload electricity production in Tunisia.

Specially designed components for use in the conversion of open-circuit apparatus to military use.

This means policy-makers must organise complex electronic communications in an open circuit, i.e. where the receiver of information (the public purchaser) does not previously know all the potential senders (the bidders).
