Abstract: Embodiments of the present application provide a transaction processing method, a device, and a storage medium. For a distributed transaction, it is proposed innovatively that exclusive locks are added to data records involved in a read set of the distributed transaction in a read phase; in a write phase, write operations for a write set can be directly executed based on these exclusive locks, and an exclusive lock on a related data record can be released immediately after a write operation is completed. In the write phase, the exclusive locks added to the data records can maintain the exclusivity of the distributed transaction over these data records, which can avoid the write operation abort problem in the write phase. That is, all write operations of the distributed transaction are bound to succeed, thereby ensuring the atomicity of distributed transaction processing.

Abstract: A system that uses autonomous robots for 3D manufacturing an object where the robots have different tool heads for performing different manufacturing operations.

Abstract: The present invention provides a swarm manufacturing platform, based on a swarm 3D printing and assembly (SPA) platform as a model for future smart factories, consisting of thousands of IoT-based mobile robots performing different manufacturing operations with different end effectors (e.g., material deposition, energy deposition, pick and place, removal of materials, screw driving, etc.) and real-time monitoring. The swarm manufacturing platform transforms a 1-D factory into a 2-D factory with manufacturing robots that can move across the 2-D factory floor, work cooperatively with each other on the same production jobs, and re-configure in real-time (i.e., the manufacturing robots can be digitally controlled to move, re-group, calibrate, and work on a new job in real-time).

Abstract: A method and apparatus for controlling a virtual camera in a game are disclosed. In the present disclosure, it is detected whether a movement of a virtual character toward a first direction satisfies a preset condition, when the preset condition is satisfied, a shifting direction of the virtual camera is determined, and the virtual camera is controlled to shift toward the shifting direction while moving according to a change of position of the virtual character, thereby a game scene image captured by the shifted virtual camera is displayed on a Graphical User Interface (GUI).

Abstract: A method and apparatus for controlling a virtual camera in a game are disclosed. In the present application, a virtual camera is controlled to shift in response to a first touch operation for a visual field control region, and the virtual camera is controlled to enter a locked state according to a locking operation, thereby locking a game scene captured by the shifted virtual camera as a game scene rendered on a graphical user interface until restoring to control the movement of the virtual camera according to the position change of a virtual character when the locked state is unlocked.
