This course aims to provide a mathematical foundation for learners, covering key concepts such as vectors, limits, derivatives, integrals, differential equations, sequences, and series. These topics ...

Abstract: In this paper, derivatives of mutual information for a general linear Gaussian vector channel are considered. We consider two applications. First, it is ...

Abstract: This paper presents two low-frequency high-directional electrochemical second-order hydrophones based on the velocity gradient pure partial derivative (VGP) and the velocity gradient mixed ...
