Abstract: Direction-of-arrival (DoA) estimation plays a critical role in applications of acoustic localization. This work proposes a closed-form algorithm for single-source one-dimensional direction ...

Abstract: Unlike acoustic pressure sensors, acoustic vector sensors (AVSs) measure both acoustic pressure and particle velocity. Circular AVS arrays, made up of multiple vector sensors, offer better ...

The megalithic site of Gunung Padang in the highlands of western Java was constructed some 2,000 years ago over the course of several generations. Similar stone monuments are found across the ...
