    Optimal design of hollow conductor for high‐speed synchronous motor exploiting adaptive‐sampling radial basis function algorithm by Ruiye Li, Peng Cheng, Hai Lan

    Published 2024-12-01
    “…To address this, the paper proposes a multi‐objective optimisation method based on adaptive sampling radial basis function (ASRBF). The ASRBF algorithm adaptively adds sample points by estimating expected improvements at prediction points, enabling the surrogate model to rapidly approximate the global optimum while significantly reducing function evaluations. …”

    Bit error rate performance analysis of SIMO-UWOC systems in fading environments by ZHU Jiabin, LI Yueheng, WANG Weijie

    Published 2025-05-01
    “…In the marine turbulence fading environment, a hybrid fading channel model was considered, which included the effects of generalized Gamma distribution (GGD) marine turbulence, zero-mean axis pointing errors, and path loss. Using the Meijer-G function, the average bit error rate for a single-input multiple-output (SIMO) underwater wireless optical communication (UWOC) system employing selection combining (SC) was derived. …”
