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 ...

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: 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 ...

Abstract: A low profile and broadband sequential rotation array of circularly-polarized metasurface antenna elements at Ka-band is proposed in this paper. The antenna element includes a ...

Abstract: In this paper, a fast direction of arrival (DOA) estimation algorithm based on rotation array for intelligent transportation system (ITS) is proposed. The vehicle radar system is the ...
