Though the Fibonacci sequence shows up everywhere in nature, these young mathematicians were surprised to find it in the ...

Spherical microphone arrays, with their geometrically optimised arrangements of detectors, have become an indispensable tool for capturing full sound fields in three dimensions.

In this article, two efficient algorithms for source direction finding and direct localization using a UAV array are, respectively, presented. First, the array manifold changes with the movement of ...

This paper presents a direction-of-arrival (DOA) estimation method of three-element array based on linear frequency modulation waveforms (LFMW). The signals with phase difference generated from the ...

I take this $30 pocket multitool everywhere, and keep finding new uses for it I typically rely on more expensive multitools, but the NexTool E1 impressed me with a rugged build and competitive ...
