Abstract: This study proposes the time-modulated array (TMA) based rotating electric-field vector (REV) method as a means of extracting the angle information of the incoming fully correlated signals.

Abstract: This paper presents the critical-point-based stability analyses of finite-difference time-domain (FDTD) methods for Schrödinger equation incorporating vector and scalar potentials. Most ...

We describe computationally efficient methods for Bayesian model selection. The methods select among mixtures in which each component is a directed acyclic graphical model (mixtures of DAGs or MDAGs), ...
