Abstract: A model generation system includes input and output units. The input unit receives a plurality of input value trajectories comprising operational input value trajectories and simulation input value trajectories relating to an industrial process. The processing unit implements a simulator of the industrial process and generates behavioral data for at least some of the plurality of input value trajectories. The processing unit further implements a machine learning algorithm that models the industrial process, and trains the machine learning algorithm.

Abstract: Systems and methods for reliable flow measurement and control may include a processor having multiple cores. The compute device may further include circuitry configured to identify a time-critical software application to satisfy a target execution parameter for the measurement or control of fluid flow in an industrial environment. The circuitry may be further configured to allocate at least one resource of the compute device to execute the time-critical software application in satisfaction of the target execution parameter with at least one other software application in a single operating system, including dedicating a core of the processor to the execution of the time-critical software application. Additionally, the circuitry may be configured to execute the time-critical software application with the at least one other software application in the single operating system in satisfaction of the target execution parameter.

Abstract: A transducer for non-invasive measurement includes: a shear-type piezoelectric element; and a host material. The shear-type piezoelectric element is mounted to a first face of the host material. A second face of the host material is mountable to a wall of a vessel that holds a liquid. When the second face of the host material is mounted to the wall of the vessel, the transducer when activated at an activation frequency launches a Lamb wave into the wall of the vessel. The transducer is designed such that a phase velocity of the Lamb wave in the wall of the vessel is greater than a speed of sound in the liquid held by the vessel.

Abstract: A sealing device (10) for providing a fluid-tight sealing of a joint comprising a first part (30) and a second part (32) with a relative movement in between. The sealing device (10) comprises: an outer sealing part (12) designed to contact the first part and the second part, an inner sealing part (14) designed to contact the first part and the second part, and a spacing structure (16) connecting the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) define an intermediate space (18) between the outer sealing part (12) and the inner sealing part (14). The outer sealing part (12) and the inner sealing part (14) are being configured to seal off the intermediate space (18) from both an exterior and an interior of the joint, and the intermediate space (18) is configured to be influid contact with both the first part (30) and the second part (32).

Abstract: In one aspect, a quasi-resonant turn-off circuit is provided. The quasi-resonant turn-off circuit is couplable in parallel with a pair of anti-parallel thyristors. The quasi-resonant turn-off circuit includes a resonant capacitor and an energy recovery circuit. The resonant capacitor is configured to supply a charge to the pair of anti-parallel thyristors to decrease a turn-off time of the pair of anti-parallel thyristors. The energy recovery circuit is configured to recharge the resonant capacitor using remnant energy left in parasitic inductances coupled to the quasi-resonant turn-off circuit after the pair of anti-parallel thyristors is off.
