Location-Aware Source Routing Protocol for Underwater Acoustic Networks of AUVs
Journal of Electrical and Computer Engineering, 2012 Acoustic networks of autonomous underwater vehicles (AUVs) cannot typically rely on protocols intended for terrestrial radio networks. This work describes a new location-aware source routing (LASR) protocol shown to provide superior network performance ...

Deciphering acoustic emission signals in drought stressed branches: the missing link between source and sensor [PDF]
, 2015 When drought occurs in plants, acoustic emission (AE) signals can be detected, but the actual causes of these signals are still unknown. By analyzing the waveforms of the measured signals, it should, however, be possible to trace the characteristics of ...
