In the first alternative, the reactor core is fully “nonproliferative,” since neither the reactor fuel nor the wastes generated can be used to produce nuclear weapons. In the second version of the invention, the reactor core is used to burn large amounts of weapons-grade plutonium together with thorium and provides a suitable means to destroy stockpiles of weapons-grade plutonium and convert the energy released to electric power.

US08116269B2 Methods for optimal multi-channel assignments in vehicular ad-hoc networks
A communications path is established among an ordered sequence of moving nodes, representing vehicles. Available channels may differ from one node to the next node and a node cannot use the same channel for both receiving and transmitting information. Three methods are described that provide an optimal sequence of channel assignments between the nodes. A sequence of channel assignments is called optimal if it establishes a communications path from the first node in the sequence to the last node in the sequence, or, if such a path does not exist, from the first node to the farthest node possible in the sequence. The first method uses a depth-first search starting from the first node in the sequence. The second method uses a “look ahead” scheme in the depth-first search method. The third method requires only a single pass through the sequence of nodes by identifying optimal channel assignments in subsequences of nodes without a need for backtracking.

The torque characteristic is improved using a magnetic flux efficiently, and an eddy-current loss generated in a coil is reduced. Moreover, a loss is suppressed even if a metal member having a high thermal conductivity is closely disposed or closely contacted to a coil surface exposed by a variable magnetic field to improve the heat transfer property, thereby improving the cooling capability. A coil assembly for a rotational electric apparatus has first and second coil plates having wiring patterns formed in such a way that conductive coil segments adjoin with each other via slits, magnetic-flux-transfer-member slots formed in the slits and having a wider width than such slits, a coil constituted by the stacked coil plates so that the magnetic-flux-transfer-member slots overlap with each other, and a magnetic flux transfer member inserted into the magnetic-flux-transfer-member slots of the coil.
