Abstract: An approach is provided for discovering social ties among users based on cloaked trajectories. In a method, cloaked regions of a first trajectory of a first user and cloaked regions of a second trajectory of a second user are transformed to corresponding semantic regions, respectively, wherein a semantic region is expressed with a semantic meaning of a corresponding cloaked region. The transformed semantic regions are mapped into nodes of a hierarchical semantic tree, wherein each node of the hierarchical semantic tree corresponds to a semantic region. According to relationships between nodes mapped to semantic regions of the first trajectory and node mapped to the semantic regions of the second trajectory, social ties among the first user and the second user can be inferred.

Abstract: The present invention provides a seal assembly for use in a centrifugal compressor and a centrifugal compressor having same. The centrifugal compressor comprises an impeller and a housing, wherein the impeller comprises a gimbal, provided on the back of the impeller, having an inner diameter and an outer diameter; and the seal assembly for use in a centrifugal compressor comprises a sealing section, the sealing section comprising a sealing tooth formed on the impeller and a sealing ring provided on the housing, wherein an elastic part is provided on a contact surface of the sealing ring with the sealing tooth. According to the seal assembly of the present invention, the sealing clearance between the sealing ring and the sealing tooth is effectively reduced by way of multiple sets of sealing sections and the elastic parts provided therebetween.

Abstract: A method, apparatus, system for image processing is provided that creates an object note for a picture.
