Fast TDOA and FDOA Estimation for Coherent Pulse Signals

Time difference of arrival (TDOA) and frequency difference of arrival (FDOA) have been widely used for localizing temporally continuous signals passively.Temporal sparsity of pulse signals makes their TDOA and FDOA estimation processes much different, and computational complexity is a major concern in this area.This paper addresses the problem of f

Fish, mirrors, and a gradualist perspective on self-awareness.

The mirror mark test has encouraged a binary view of self-awareness according to which a few species possess this capacity Bags - Tote whereas others do not.Given how evolution works, however, we need a more gradualist model of the various ways in which animals construe a self and respond to mirrors.The recent study on cleaner wrasses (Labroides di
