TL;DR: In this article, the received signal is a linear combination of delayed and attenuated uncorrelated replicas of the source emitted waveform, and the set of delays and attenuations, together with the channel environmental conditions, provide sufficient information for determining the source location.

TL;DR: Two algorithms are proposed, one of which restores constructive interference between sensors, and the other one minimizes the output residual as in widely used equalization schemes, which are shown to improve the residual error and temporal stability of basic time reversal with very little added complexity.

TL;DR: This paper provides a data consistent model for the observed signal, formed by a deterministic channel structure multiplied by a perturbation random factor plus noise, and shows that the proposed processor has the same performance as the matched-phase processor at the maximum of the ambiguity surface, without the need for estimating the phase terms and thus having an extremely low computational cost.

TL;DR: Swimming performance in young swimmers appeared to be dependent on swimming efficiency, which is determined by the remaining variables assessed, except for the hand surface area, so young swimmer coaches and practitioners should design training programs with a focus on technical training enhancement.

TL;DR: The particle velocity information provided by the VSA increases significantly the resolution of seabed parameter estimation and in some cases reliable results are obtained using only the vertical component of the particle velocity.
