In this paper, we present a novel fine-grained access control system for applications where the information flow is critical; the confidentiality of the data is essential and there...
— Despite its low-complexity, the zero-forcing receiver is known to suffer from noise enhancement to restore the spatially multiplexed data in a single-user MIMO system. Neverthe...
Abstract. We introduce an operator-based scheme for preconditioning stiff components encountered in implicit methods for hyperbolic systems of PDEs posed on regular grids. The met...
