When astronomers first started finding “odd radio circles,” or ORCs, they were baffled. These faint, ghostly rings of radio ...

Welcome to the Data Structures and Algorithms Repository! My aim for this project is to serve as a comprehensive collection of problems and solutions implemented in Python, aimed at mastering ...

Abstract: Two-dimensional Direction of arrival (2D DOA) is a challenging problem in sparse circular arrays (SCAs), especially in the field of underdetermined estimation. In this paper, based on sparse ...
