    Bootstrap Statistical Model of Tooth Surface Deviation of Heat Treatment Deformation of Batch Spiral Bevel Gears by Weihao Sun, Jubo Li, Tianxing Li, Chuang Jiang, Songlin Wang, Jianxin Su

    Published 2022-08-01
    “…Aiming at the same batch of spiral bevel gears with the same gear material, NC milling method and heat treatment specification, a bootstrap resampling is carried out on a small number of tooth surface deviation sample data based on the bootstrap method, a large number of sample data are obtained and a bootstrap statistical model of batch spiral bevel gear tooth surface deviation is established; the probability characteristic value of the sequential points of tooth surface measurement is calculated, and whether they conform to the normal distribution is tested by <italic>k</italic>-<italic>s</italic>; the estimated true value, estimated interval and other parameters are selected to describe their statistical laws and results; through the cubic NURBS surface fitting method, the variation law of the tooth surface deviation of the whole batch is obtained, and the effective evaluation of the tooth surface accuracy of the whole batch is realized. …”

    The effect of resizing on the natural appearance of scintigraphic images: an image similarity analysis by Siraj Ghassel, Amir Jabbarpour, Jochen Lang, Eric Moulton, Eric Moulton, Ran Klein, Ran Klein, Ran Klein, Ran Klein

    Published 2025-02-01
    “…Background and objectiveThis study aimed to assess the impact of upsampling and downsampling techniques on the noise characteristics and similarity metrics of scintigraphic images in nuclear medical imaging.MethodsA physical phantom study using dynamic imaging was used to generate reproducible static images of varying count statistics. Naïve upsampling and downsampling with linear interpolation were compared against alternative methods based on the preservation of Poisson count statistics and principles of nuclear scintigraphic imaging; namely, linear interpolation with a Poisson resampling correction (upsampling) and a sliding window summation method (downsampling). …”
