  • Publication number: 20170124493
    Abstract: The present invention relates to a business process management system. The business process management system includes a database, a memory device and a business process management engine. The database is configured to store a business process model and configured to create storage fields in advance for a plurality of process variables included in the business process model according to at least one artifact corresponding to the business process model. The at least one artifact records an association between the process variables and the created storage fields. The business process management engine is configured to copy the business process model from the database to the memory device to execute the business process model at the memory device and configured to simultaneously store variable values corresponding to the process variables from the memory to the created storage fields of the database according to the association during executing the business process model.

  • Publication number: 20150125028
    Abstract: An electronic device and a video object motion trajectory modification method thereof are provided. The electronic device includes a video providing unit and a processing unit. The video providing unit is configured to provide a video. The processing unit is configured to extract a video segment from the video. The video segment includes a plurality of successive frames which include a common object. The processing unit is further configured to calculate at least one curve and one control point thereof. The at least one curve corresponds to a motion trajectory of the common object in the successive frames. The processing unit is also configured to adjust the at least one curve via the control point to modify the motion trajectory. The video object motion trajectory modification method is applied to the electronic device to implement the aforesaid operations.
