Abstract: Vehicle license plate auditing is provided. Distance and time traveling information corresponding to a vehicle is extracted from a data network analysis graph model of spatiotemporal traffic flow data based on a license plate number of the vehicle in response to removing irrelevant nodes from the data network analysis graph model. A distance and time mutually exclusive node relationship is determined within the data network analysis graph model of spatiotemporal traffic flow data based on the distance and time traveling information corresponding to the vehicle extracted from the data network analysis graph model of spatiotemporal traffic flow data. An anomalous license plate node is determined in the data network analysis graph model of spatiotemporal traffic flow data based on the distance and time mutually exclusive node relationship. A set of action steps is performed regarding an anomalous license plate number corresponding to the anomalous license plate node.

Abstract: A method for fabricating a metallic member includes providing a pre-forging mould. The pre-forging mould comprises an upper mould and a lower mould. The lower mould defines a pre-forging chamber, and a die cavity defined in a bottom surface of the pre-forging chamber. A metallic stock is placed above the die cavity, and the upper mould is moved toward the lower mould to forge the metallic stock, thereby forming a pre-formed body comprising a forging portion and a pre-forged base; annealing the pre-formed body; providing a forging mould to forge the pre-formed body, thereby obtaining a forged-body with a forged base thinner than that of the pre-forged base. Then the forged-body is milled to a desired size, and sandblasted, thereby obtaining the metallic member.
