Both effects of underlying temporal decorrelation of ...
Autonomous underwater vehicles can be valuable acoustic sensing platforms due to their maneuverability, low cost, and sensor-driven adaptivity compared to ships. However, the logistics of integrating acoustics research into artificially intelligent systems can be daunting. In this work, the autonomy softw...
With the proliferation of Internet-of-Things (IoT) devices, acoustic sensing attracts significant attention in recent years. It exploits acoustic transceivers such as microphones and speakers beyond their primary functions, namely recording and playing, to enable novel applications and new user experiences...

In this addendum, we offer a hypothetical mechanistic explanation as to how plants may do this by quantum-assisted magnetic and/or acoustic sensing and signaling. If proven correct, this hypothesis prompts for a re-interpretation of our current understanding of plasticity in germination and growth ...
acustic sensing for touch recognition in a social robot Perceiving when, where and how a robot is touched is an important aspect towards a natural Human-Robot Interaction (HRI). To date, several technologies are used in Social Robotics to determine the area where a touch is performed, in some...
