Distance bounding protocols are pivotal in contemporary security systems, designed to verify the physical proximity of a device by measuring the round-trip time of cryptographic challenge–response ...

Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...

If you're a casual track and field fan, you've probably heard of the 4x100 and 4x400 meter relays and can likely deduce how they are run from the names of the events alone. However, those are not the ...
