Abstract: The present disclosure relates to a field of door/window hardware accessories, in particular to a door/window pulley, a pulley device, and a door/window. The present disclosure provides the bearing and the anti-deformation metal ring that can be in contact with the track, the anti-deformation metal ring use rigidity itself to effectively avoid generating indentation, and the door/window pulley is also difficult to be pressed to cause deformation. Moreover, the inner part of the injection molded body is filled between the bearing and the anti-deformation metal ring, which not only well transfers pressure bore by the anti-deformation metal ring when load-bearing to the bearing, but also restores the anti-deformation metal ring after slight deformation by giving an outward elastic support to the anti-deformation metal ring using elasticity of the injection molded body.

Abstract: The invention discloses a pull-up device capable of training finger grip force. It is equipped with bracket to fix the left and right climbing components in the air. Meanwhile, the climbing component is equipped with knuckle receiving portion to permit the fingers to hold the knuckle receiving portion for pull-ups. With the setting of the climbing component, we no longer hold the crossbar, but just grip the climbing component by the fingers when we do pull-ups. Thus, the grip force of the knuckle muscles is exercised as well as the arm strength.

Abstract: A method and system of discovering and analyzing structures of user groups in a microblog is provided in this invention. The method of discovering and analyzing structures of the user groups in a microblog comprises: acquiring information on behavior data of microblog users of a target group; constructing a microblog user association network based on the information on behavior data of the microblog users of the target group; acquiring at least one maximal clique from the microblog user association network; acquiring at least one core clique based on the maximal clique; and conducting behavior analysis on the user groups in the microblog based on the acquired maximal clique and/or the acquired core clique.

Abstract: Provided are a method and system for identifying microblog user identity. The method comprises obtaining behavioral data of a user to be identified and feature library information of user behavior, reprocessing the obtained behavioral data of the user to be identified, performing semantic unit reconstruction on the preprocessed user behavioral data, and obtaining attribute information and its corresponding weight of the semantic unit; obtaining behavioral feature of the user to be identified based on attribute information and corresponding weight. The method further comprises comparing behavioral feature of user to be identified with each feature category in the feature library information of user behavior and determining the identity of the user to be identified of user behavior exceeds a predefined threshold. Using the provided method and system for identifying the microblog user identity, the accuracy and real-time performance of identifying the microblog user identity may be effectively improved.
