For this evidence, we will take a 1400 complexity problem from Codeforces known as "C. Theofanis' Nightmare" The problem is about Theofanis who easily gets obsessed with problems before going to sleep ...

Abstract: Dynamic subarray achieves a compromise between the sum rate and hardware complexity of millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems, in which antenna ...

Abstract: Recently, direction of arrival (DOA) estimation for non-circular (NC) sources has attracted great attention in array signal processing since NC signals can provide more information to ...

In this paper, a novel recurrent sigma‒sigma neural network (RSPSNN) that contains the same advantages as the higher-order and recurrent neural networks is proposed. The batch gradient algorithm is ...

When preparing for Data Structures and Algorithms (DSA) interviews, it's crucial to master certain patterns that frequently arise in array problems. Here are five fundamental patterns, each explained ...

I recently reviewed interview preparation websites and realized that they’re now a decade more sophisticated than when I last interviewed. But I now have more than a decade of experience as a Google ...

We propose a scheme for scalable and robust quantum computing on two-dimensional arrays of qubits with fixed longitudinal coupling. This opens the possibility for bypassing the device complexity ...

Yash is an aspiring computer science student who loves to build things and write about all things tech. In his free time, he likes to play Squash, read a copy of the latest Murakami, and hunt dragons ...

The NEC permits photovoltaic (PV) systems to supply power to buildings, structures, or other electrical supply system(s). PV systems can be installed on or in a single structure. Where multiple power ...
