Abstract: A pavement anti-skid performance evaluation method based on envelope feature is provided. A surface profile image of a to-be-tested piece is acquired as a blank background image. A motion trajectory image of a sliding piece on the to-be-tested piece is acquired. The blank background image is treated to obtain a surface texture profile curve of the to-be-tested piece. The motion trajectory image is differenced with the blank background image to obtain a difference image, which is treated to obtain a trajectory envelope curve of motion of the sliding piece on the to-be-tested piece. An arithmetic mean of the trajectory envelope curve and an arithmetic mean of the surface texture profile curve are calculated, and the anti-skid performance is evaluated based on a height difference ?h between above two arithmetic means. A pavement anti-skid performance evaluation device based on envelope feature is also provided.

Abstract: The present disclosure provides a carrier aggregation capability reporting apparatus and method, so as to prevent a user equipment (UE) from repeatedly reporting capability information corresponding to a carrier combination supported by the UE, and reduce waste of signaling resources used for reporting. The method includes: determining, by the UE, information about a carrier combination supported by the UE and information about a sub-combination that is of the carrier combination and that is supported by the UE; and reporting, by the UE to a base station, the determined information about the carrier combination supported by the UE and the determined information about the sub-combination that is of the carrier combination and that is supported by the UE.

Abstract: Systems and methods for relating configuration data to IP cameras are provided. Some methods can include a video streaming server device receiving a message identifying an IP address of an IP camera from a DHCP server device, the video streaming server device using the IP address to connect to the camera, the video streaming server device receiving a video data stream from the camera, the video streaming server device extracting a MAC address of the camera from a connection with the IP camera, the video streaming server device transmitting the video data stream, the IP address, and the MAC address to a mobile device, a manager server device receiving configuration information for the IP camera, the IP address, and the MAC address from the mobile device, and the manager server device relating and binding the configuration information with the IP address and the MAC address.
