Abstract: The hyperbolic tangent function is a crucial aspect of navigation, communication, and activation function in neural networks and other modern digital signal processing systems. This paper ...

Tessellations aren’t just eye-catching patterns—they can be used to crack complex mathematical problems. By repeatedly reflecting shapes to tile a surface, researchers uncovered a method that links ...

Abstract: In this paper, a novel method is proposed for direction of arrival (DOA) estimation in the presence of impulsive noise. By introducing the hyperbolic secant function into the framework, a ...
