Abstract: The present disclosure provides a molding system for fabricating a FRP composite article. The molding system includes a detector, a resin dispenser, a processing module, and a molding machine. The detector is configured to capture a graph of a woven fiber from a top view. The resin dispenser is configured to provide a resin to the woven fiber to form a FRP. The processing module is configured to receive the graph and a plurality of parameters of the FRP. The processing module includes a CNN model, and is configured to use the CNN model to obtain a plurality of predicted mechanical properties of the FRP according to the graph and the plurality of parameters of the FRP. The molding machine is configured to mold the FRP to fabricate the FRP composite article according to the plurality of predicted mechanical properties.

Abstract: An axial-flow heat dissipation fan including a frame, a hub, and a plurality of blades is provided. The frame has an air inlet and an air outlet. The hub is rotatably arranged in the frame. The blades disposed at side of the hub respectively and rotate along with the hub. Each of the blades has a front surface facing toward the air inlet and a rear surface facing toward the air outlet. A surface roughness of the front surface is different from a surface roughness of the rear surface.

Abstract: A method and system that provides a user with precision and accuracy of recommended information that matches the user's personality and behavior by obtaining the location of the user's mobile terminal, determining a target area based on the location, the target area including more than one signal transmission source, each signal transmission source carrying an ID that represents the signal transmission source, and the ID carried in the signal transmission source being transmitted within a target range by using the signal transmission source, obtaining other information from the terminal including user basic information and/or user behavior information and/or user relation chain information, selecting target display information associated with this information from the display information associated with the more than one ID of the terminal, and sending the target display information to the terminal.
