For the sake of size, the audio in these examples uses the mp3 format. This may cause the audio to be slightly desynchronized with the animation (The displayed waveform remains correct). wav files don ...

Abstract: In this paper, we propose a novel distortion calibration algorithm for uniform circular array (UCA) based on its special structure. A near-field calibration antenna, located in the center of ...

The New Scientist Book Club made a jump backwards through time for our latest read, Alex Foster’s Circular Motion, moving from the millennia-ahead future of Adam Roberts’s Lake of Darkness to a world ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Abstract: A calibration method based on orbital angular momentum (OAM) is proposed for gain-phase errors in uniform circular array (UCA). The idea of the method is to construct an objective function ...

A striking composition where swirling colors wrap around a circular frame, creating a sense of movement and energy within a balanced, enclosed space. Crime sparks state of emergency in New Mexico: ...
