Distributed Control with Low-Rank Coordination

A common approach to distributed control design is to impose sparsity constraints on the controller structure. Such constraints, however, may greatly complicate the control design procedure. This paper promotes an alternative structure, which is not sparse, yet might nevertheless be well suited for distributed control purposes. The structure appears as the optimal solution to a class of coordinati

A Source-Based Test-Bed for Fast-Neutron Irradiation

The "3He crisis" has resulted in a major effort worldwide to develop replacement neutron-detector technologies. Such technologies are in their infancy and need to be thoroughly tested before becoming mainstream. Neutron sources for controlled irradiation include accelerators, nuclear reactors and radioactive sources. Neutrons produced in nuclear reactors and at accelerators have a very high cost p
