Earth is expected to spin more quickly in the coming weeks, making some of our days unusually short. On July 9, July 22 and Aug. 5, the position of the moon is expected to affect Earth's rotation so ...

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly.

Abstract: A fast algorithm for evaluating the cross-polarization characteristics of sequentially rotated circular polarization phased array is presented, which can be used to design a specific array ...

Abstract: In this paper, we present a novel framework of beamforming robust for a microphone array rotation. In most array signal processing methods, the time-invariant transfer system from a source ...

ABSTRACT: At a substation, the condition of an applied voltage is checked using a bulky contact-type electroscope. Although it is important to secure a safe working environment, it is a burden to ...
