Abstract: Provided are a vibration object monitoring method and apparatus, a computer device, and a storage medium. The method includes: in response to detecting that a vibration object exists in a monitoring video picture for a target monitoring region, a vibration object region in the monitoring video picture is determined, where the vibration object region is a region where the vibration object is located in the monitoring video picture; displacement information of a key point of the vibration object in the vibration object region is recorded; vibration information of the vibration object in the monitoring video picture is determined based on the displacement information; and a vibration object monitoring result for the target monitoring region is generated according to the vibration information. The abnormal vibration monitoring can be performed on the vibration object in the target monitoring region in time according to this method.

Abstract: An end cover assembly, an air cylinder, a tread sweeper and a railway vehicle.

Abstract: A radiotherapy system (220, 320) comprises a first rotary support apparatus (204, 304) configured to support a radiation beam source (200, 300) and to cause a radiation beam source (200, 300) to rotate about a rotation axis (218, 318, 518), a second rotary support apparatus (214, 314, 414, 514) and a radiation shield (202, 302, 402, 502) mounted to the second rotary support apparatus (214, 314, 414, 514). The second rotary support apparatus (214, 314, 414, 514) is configured to cause the radiation shield (202, 302, 402, 502) to rotate about the rotation axis (218, 318, 518).

Abstract: The present invention provides a method for controlling a remote service access path including the steps of: receiving a datagram sent by any terminal intending to access the remote service; requesting a node management server to determine an optimal gateway server as an optimal node for transferring the datagram, the optimal gateway server being selected from a number of gateway servers provided for a distributed deployment architecture established for a server cluster of the remote service; testing transmission quality of a number of accessed data connections to the optimal gateway server, and determining an optimal data connection having optimal transmission quality; and invoking the optimal data connection to send a datagram after tunnel encapsulation thereof, and the optimal gateway server forwarding the datagram to a business server connected to the optimal gateway server and belonging to the server cluster.

Abstract: Database report generation technology for handling a single logical query that requires data that is physically located in two different sources. The system uses intelligent push-down joins, which move data from one source to the other and join data within that source. The system dynamically determines which direction to move data depending on how the data is used in a query.

Abstract: Dynamic sourcing, in which a data request that is associated with a query is received and a parameter of data needed for satisfaction of the query is identified. Parameter information defining data available in at least one cube stored in a cache is accessed and the parameter is compared with the parameter information. Based on comparison results, it is determined whether one or more cubes in the cache include sufficient data to satisfy the query. In response to a determination that one or more cubes include sufficient data to satisfy the query, a response to the data request is generated by executing the query against the one or more cubes. In response to a determination that the cubes do not include sufficient data to satisfy the query, a response to the data request is generated by executing at least a portion of the query against a database system.

Abstract: A system and method for creating a custom grouping of data in a database. A custom group object is created, a plurality of custom group elements are defined, each of the custom group elements being a subset of the custom group object and being defined by a different filter, each one of the different filters representing a logical expression of qualifications based on the data or a derived calculation of the data. Each of the different filters is resolved against the data or a subset of the data, and the plurality of custom group elements are grouped into a consolidated result set which in not naturally existing in the data structure.
