Abstract: This paper presents a novel flexible sparse antenna array (FSAA) design that improves angular resolution in direction-of-arrival (DOA) estimation. In contrast to conventional fixed arrays, ...

This works because each single rotation preserves the relative order of elements while moving the last element to the front. The algorithm starts by handling edge cases: if k is 0 or the array is ...

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.

House chores come with the season, and cleaning out your closet is one of them. Maybe you've shopped over the past few months and your closet has become a bit overwhelming (or a frenzied mess, for ...

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: 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 ...
