Abstract: A system and method for remote object sensing which features a spatially polarization-inhomogeneous light beam that is directed on the remote object. A polarimetry receiver receives the light beam after it contacts the remote object. The changes in the spatially polarization-inhomogeneous light beam from contacting the remote object are a result of spatial features of the remote object. The polarimetry receiver is configured to measure the spatially inhomogeneous electric field of the light beam after it contacts the remote object and compute the changes in the spatially polarization-inhomogeneous light beam in order to detect spatial features of the remote object. The system obtains high-resolution, real-time information concerning important spatial features of the remote object.

Abstract: A system and method for network virtualization and resource allocation, including storing one or more received network requests in a request table, and updating at least one of a flow table, a waiting list table, or a candidate group map based on the one or more received network requests. The updating includes monitoring a transmission progress of each of one or more flows in a network of interconnected computing devices and moving completed flows from the flow table to a success list, moving requests in the waiting list table which have reached an attempt threshold from the flow table to a fail list, and compiling any residual requests in the waiting list with new requests to generate a new request table. A deterministic request allocation and/or an optimizing request allocation is performed based on the new request table.

Abstract: A generic centralized, software-defined networking configuration for connecting network is defined as a generic multi-layer topology network entities interconnected either vertically or horizontally regardless of the employed network topology/graph). This centralized configuration enables establishment of a connection between any two networking entities by 1) bypassing intermediate protocol layers and 2) eliminating any handshaking between peer elements of the same layer. The centralized software-defined controller notifies in parallel all involved network entities along a connection path to take all necessary actions (i.e. reconfiguration) to establish the new connection. The centralized controller has authority to control only entities that are software-defined SD.
