AbstractAiming at the problems that the abnormal state of high-speed liquid packaging production lines is difficult to identify in time, the computing power of edge controller is limited, and the energy consumption regulation and condition monitoring are separated from each other, a multimodal lightweight artificial intelligence (AI) system embedded in Tech-Long production controller is constructed; this realizes the collaborative optimization of abnormal operation window identification and energy consumption of the whole line. First, this study collects vibration, acoustic, and thermal signals from the bottle blowing, filling, and packaging sections; it also constructs cross-sectional anomaly characterization through time synchronization, feature-level alignment, and hierarchical fusion.

AbstractTo support the performance optimization of electrostatic precipitators (ESPs) for potential aerospace applications, a coupled numerical model integrating the discrete phase model (DPM) with user-defined scalar (UDS) transport equations was developed to resolve the electric-field characteristics and particle transport behavior within the ESP. Focusing on the structural optimization of the discharge electrode and collection plate, four representative ESP configurations were established for comparison: a conventional flat-plate type, a W-type, a W1-type combining a corrugated collection plate with an auxiliary electrode, and a single-electrode type. The effects of a pre-installed filter screen, the internal airflow distribution, the electric-field and charge-density characteristics, and the relationship between particle trajectories and collection efficiency were systematically investigated.

The spacecraft delivered materials and equipment for new research studies to the station.

The history of life on Earth doesn’t start with the Cambrian Explosion. However, this was the point in time that nearly all major animal groups appeared, proliferated, and diversified. It wiped out 90% of life on Earth, turned the oceans into graveyards – and it very nearly ended life on our planet entirely
