Here is how G.P.S. works: a constellation of satellites transmits radio signals that allow receivers on the ground to pinpoint longitude, latitude and altitude.
He noted that the Central Bank had acted aggressively once it knew what had happened at Kabul Bank, replacing its management and breaking the bank up to allow receivers to pursue the bad loans.
The buffer will allow receivers that may have "missed" one signal because of interference -- say, being in a tunnel or behind a mountain -- to pick up the second signal, re-synchronize and continue uninterrupted play.
In other words, IDNC techniques shift the computational load to the sender, and allow receivers to perform simple binary XOR based instant packet decodings, as the sender (such as a base station) usually has much more computational and energy resources than the receivers.
On the other hand, differentiating between callers would allow receivers to decide whether or not to join a foraging group.
Raven yells may thus allow receivers to extract essential social features about the caller, that is, whether it is young or old and male or female.
