    Bivariate power Lomax Sarmanov distribution: Statistical properties, Reliability measures, and Parameter estimation by M.A. Abd Elgawad, M.A. Alawady, H.M. Barakat, G.M. Mansour, I.A. Husseiny, Salem A. Alyami, Atef F. Hashem, M.O. Mohamed

    Published 2025-02-01
    “…For modeling bivariate life expectancy data, this model provides a significant lifetime distribution. Several statistical properties of the BPL-SARD are derived and discussed, such as marginal distributions, product moments, coefficients of correlation between the inner variables, conditional distributions, conditional expectations, moment-generating functions, and the positive quadrant dependence property. …”

    A Normal Contact Stiffness Statistical Model of Joint Interface considering Hardness Changes by Donghua Yin, Xueliang Zhang, Shuhua Wen, Guosheng Lan, Yonghui Chen

    Published 2022-01-01
    “…., the deformation stage of an asperity is re-divided, and a normal contact stiffness model of joint interface is established by using a statistical theory. The simulation results show that the normal contact stiffness of joint interface is a nonlinear function of the mean surface separation and decreases with the increase of the mean surface separation under different plasticity indexes. …”

    A Method of Arrival Angle Optimization in Single-Station Positioning Based on Statistical Features by Ting Li, Tongxin Liu, Xuehai Yang, Guobin Yang, Chunhua Jiang, Chongzhe Lao

    Published 2025-01-01
    “…Aiming to mitigate the substantial dispersion in arrival angle estimation due to colored and white noise interference, which may seriously affect the accuracy of short-wave single-station positioning, this paper introduces an approach to optimizing angles based on the statistical features. By utilizing the extraction of the main peak area of the probability density distribution of the measured angle, as well as the two-dimensional Gaussian fitting and confidence ellipse bounding, the angle measurement results affected by colored noise interference and the noise points with large deviations can be sequentially filtered out. …”
