  • Publication number: 20190236948
    Abstract: An intersection management system (IMS) may receive one or more traversing requests from one or more Connected Autonomous Vehicles (CAVs). The IMS may determine a solution space for each of the one or more traversing requests in a space-time resource model of the intersection, find a CAV trajectory allocation in the space-time resource model for each of the one or more traversing requests. The IMS may send an approved reservation to each CAV corresponding to each of the one or more CAV trajectory allocations that have been found. Each of the one or more CAVs may, when an approved reservation corresponding to the CAV may have been received from the IMS, move through the intersection zone as specified in the approved reservation.

  • Patent number: 10348439
    Abstract: A control system for spectral slot assignment in flexible grid optical networks determines, for a given optical path, a physical source node, a physical destination node, and physical intermediate nodes, determines the number of contiguous spectral slots to allocate for traffic on the path, identifies candidate combinations of spectral slots available for the traffic, and creates an auxiliary graph for the path. The auxiliary graph includes auxiliary links representing candidate combinations of spectral slots, virtual nodes representing pairs of neighboring physical nodes, and auxiliary links between each pair of virtual source-side and destination-side intermediate nodes representing either pass-through traffic or wavelength shifted traffic.

  • Patent number: 10336931
    Abstract: The present invention relates to the well drilling field in petrochemical industry, in particular to use of dual-cation fluorocarbon surfactant as amphiphobic wettability reversal agent in drilling fluid. The dual-cation fluorocarbon surfactant is a dual-cation fluorocarbon surfactant of which the cation part is represented by the following formula (1). The dual-cation fluorocarbon surfactant of the present invention can serve as wettability reversal agent when it is used for oil-gas drilling to enable rock amphiphobic, and is an amphiphobic wettability reversal agent which can cause rock surface to be non-hydrophilic and non-lipophilic. Using of dual-cation fluorocarbon surfactant, especially when drilling highly hydrous mud shale, can avoid permeation of water and oil into the rock effectively and thereby a capillary phenomenon can be prevented, and an effect of stabilizing the well wall and protecting the reservoir is attained.
