Abstract: A control device of a processing machine actuates an axle drive of the processing machine commensurate with a reference displacement movement, displacing a mechanical structure of the processing machine accordingly. The control device determines an absolute movement of the mechanical structure in space and therefrom, taking into account the reference displacement movement of the mechanical structure, a compensation movement for a compensating mass damping a vibration of the mechanical structure. Arranged on the mechanical structure is a compensating drive which acts on the compensating mass. The control device actuates the compensating drive in accordance with the compensation movement, displacing the compensating mass relative to the mechanical structure and thereby damping the vibration of the mechanical structure.

Abstract: A system and a method for controlling the operations of a manufacturing facility with production resources that execute a production process and a manufacturing execution system with a production modeler and a production scheduler. A man-machine interface and/or graphical user interface enable the user to enter production orders and production scheduling data into the execution system. A production scheduler database stores production orders and production scheduling data. A data server process updates sensitive data that are required for real-time scheduling when a user modifies sensitive data. The data server process executes an event list queue with the data modification events launched by the database, periodically checks the event list queue for data modification events, reads from the database only the modified data of the sensitive data and/or sensitive class of data, and merges the modified data with the existing data. The updated data are then accessible to all users.

Abstract: An active oscillation damper has a balancing mass which is movable relative to an oscillating mechanical structure. The control device then determines a compensation movement for the balancing mass based on a determined three-dimensional absolute motion of the mechanical structure. A balancing drive, arranged on the mechanical structure and acting on the balancing mass, is activated by the control device. The balancing mass is displaced by the balancing drive relative to the mechanical structure commensurate with the determined compensation movement. The measured values supplied to the control device include actual values of the balancing drive and/or a position of the balancing mass relative to the mechanical structure and/or at least one derivative with respect to time of the position of the balancing mass relative to the mechanical structure. The three-dimensional absolute motion of the mechanical structure is determined by the control device from the aforementioned values.

Abstract: A method for performing automatic trace retrieval includes receiving a first and second model for a system or service (S10). The first model includes a first plurality of model artifacts at least partially represented by a first semantic style and the second model includes a second plurality of artifacts at least partially represented by a second semantic style. Training data including one or more correspondences between artifacts of the first plurality of model artifacts and artifacts of the second plurality of artifacts is collected. A semantic transformation table is generated for converting between the first and second semantic styles using the collected training data (S11). The generated semantic transformation table is used in tracing associations between artifacts of the first plurality of artifacts and artifacts of the second plurality of artifacts (S12).

Abstract: An active vibration damper has a damping device arranged on a vibration-susceptible mechanical structure. A force can be injected directly into the vibration-susceptible mechanical structure with the damping device. A damping force which damps a vibration of the mechanical structure is determined by a control device of the active vibration damper with reference to an absolute movement of the mechanical structure in space.

The control device determines the damping force such that the damping force is proportional at all times to the instantaneous velocity of the mechanical structure.
