  • Publication number: 20240344280
    Abstract: A segmental precast composite-material composite-slab composite beam and a construction method thereof are provided, relating to the technical field of bridge design and construction. The segmental precast composite-material composite-slab composite beam mainly includes a segmental precast orthotropic composite top slab, a web, a bottom slab, and a wet joint between segments. The orthotropic composite top slab is composed of an orthotropic slab and an ultra-high-performance concrete layer (UHPC), and the interface connection of the orthotropic slab and the UHPC structural layer is achieved by a shear key. The UHPC structural layer is superposed with the orthotropic slab in segments in a precast plant to form a composite-slab composite beam segment to be entirely transported, hoisted and assembled, and the connection of the UHPC structural layers between the segments is achieved by casting a transverse wet joint in place.

  • Patent number: 12094550
    Abstract: Technology is disclosed herein for detecting leaky word lines in a non-volatile storage system. The exact leaky word line may be located very rapidly using a divide and conquer approach. First a determination may be made whether at least one word line in a group such as any of the word lines in a block is leaky. This initial determination can be made very quickly. If no word line in the group is leaky, the search can end. However, responsive to a determination that at least one word line in the group is leaky, a divide and conquer search may be performed in which the group of the word lines is repeatedly divided into smaller sub-groups with selected smaller sub-groups tested for a short circuit until the leaky word line is located.

  • Patent number: 12061090
    Abstract: Deep reinforcement learning may be used for vehicle repositioning on mobility-on-demand platforms. Information may be obtained. The information may include a current location of a vehicle on a ride-sharing platform. A set of paths originated from the current location of the vehicle may be obtained. Each of the set of paths may have a length less than a preset maximum path length. A set of expected cumulative rewards along the set of paths may be obtained based on a trained deep value-network. A best path from the set of paths may be selected based on a heuristic tree search of the set of expected cumulative rewards. A next step along the best path may be recommended as a reposition action for the vehicle.
