Python, a versatile programming language, offers many tools to manipulate data structures efficiently. One such powerful tool is the filter() function, which allows you to filter elements from an ...

speed = 0.5 # speed of rotation if you want it to rotate x1 = this.x y1 = this.y z1 = this.z rotation_matrix = np.array([[u1*u1*(1-c)+c, u1*u2*(1-c)-u3*s, u1*u3*(1-c ...

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 ...
