In this article, we consider the controllability of a discrete-time linear dynamical system with sparse control inputs. Sparsity constraints on input arises naturally in networked systems, where activating each variable adds to cost control. We derive algebraic necessary and sufficient conditions for ensuring an arbitrary transfer matrix. The derived can be verified polynomial time complexity, ...

A signal recovery problem is considered, where the same binary testing posed over multiple, independent data streams. The goal to identify all signals (resp. noises), i.e., streams alternative null) hypothesis correct, subject prescribed bounds on classical or generalized familywise error probabilities of both types. It not required that exact number be a priori known, only upper numbers and no...
