Abstract: Since defect areas in collected hydro turbine defect images account for a small proportion and there is a significant color difference between surrounding background and defects, which creates too much redundant information and greatly affects detection speed, a method for detecting defects in a hydro turbine top cover based on an improved YOLOv8 model involves first cropping collected defect images to obtain cropped images, then expanding the cropped images by image enhancement techniques such as image flipping and image blurring to obtain a training dataset. A defect detection network based on YOLOv8-CBAM is constructed and trained to generate a defect detection model for detecting the defects in the hydro turbine top cover. The method achieves high precision in defect detection for the hydro turbine top cover.

Abstract: Provided is a method of reconstructing multi-source long-time-series night light data and a system thereof, relating to the field of reconstructing ecological remote sensing data. Based on night light images of a first-generation satellite DMSP/OLS (Defense Meteorological Satellite Program/Operational Line-scan System) and a second-generation satellite NPP/VIIRS (National Polar-orbiting Partnership/Visible Infrared Imaging Radiometer Suite), a method of reconstructing a set of long-time-series night light data products is developed. Since satellite images that two generations of satellites have at the same time in a certain year use an inverse hyperbolic sine transform to fit NPP/VIIRS in 2013 into a data form of DMSP/OLS, and obtain an optimal fitting equation, thus producing a set of long-time-series data products from 1992 to 2021. The method can solve a fault problem between two generations of light data of DMSP/OLS and NPP/VIRS, and improve the accuracy of data reconstruction.

Abstract: A power supply including three feedback loops: an inner voltage loop, an outer voltage loop, and a current sharing loop. The inner voltage loop is the primary regulation/conversion loop that generates the power supply output voltage. The outer voltage loop monitors the voltage at a second node that is remote relative to the power supply output which is compared to a reference. The output of the comparison is then filtered, limited, and then the output of the limiter is provided to a selector. The current sharing loop receives an indicator of output current for the power supply compared to a reference, which is the largest one of all paralleled supplies. The comparison is then filtered, limited, and then the output of the limiter is also provided to the selector. The selector output is used to offset the feedback parameter of the inner voltage loop.

Abstract: In a mobility management system and a mobility management method of a base station, position data of a connected target terminal in a cell of the base station is acquired and based thereon a moving track of the terminal is generated and the terminal's speed is determined. Based on a matching degree of the moving track of the terminal with respect to at least one track model corresponding to the speed of the terminal, a track model is selected, for which the matching degree meets a first preset condition from among the at least one track model. An initial matching degree of the moving track of the terminal with respect to the specific track model is obtained; future position data of the terminal is predicted; the initial matching degree is updated; it is determined whether the terminal is to be connected to another base station.
