Abstract: An air foil bearing includes a sleeve that defines a hollow portion having an irregular curvature, where the hollow portion is configured to receive a rotor, a bump foil that is disposed at an inner peripheral surface of the sleeve, and a top foil that is disposed at the bump foil.

Abstract: Disclosed is a data processing system and method for the fusion of multiple heterogeneous sensors. The data processing system and method may synchronize the first merged sensing signal with the second sensing signal by performing origin time shifting (OTS) and tracklet movement compensation (TMC). Namely, it is possible to perform time synchronization to the heterogeneous sensors by post-processing data without synchronizing the data acquisition time points through a trigger. Also, the data processing system removes the noise points caused by direct and indirect interference included in the first sensing signal, thereby providing more accurate sensing signal data.

Abstract: A method and apparatus for a streaming service to provide scalability and view information are provided. When a scalable video or multi-view video is transmitted using a Moving Picture Experts Group-2 (MPEG-2) system, scalability information or view information regarding the scalable video or multi-view video in a payload may be used. Using the scalability information or view information, a packetized scalable video or multi-view video may be efficiently adapted to various terminal performances, various network characteristics, a specific user preference, and the like.
