Bath Vibration During Open Eye Formation in a Physical Model of a Steelmaking Ladle
steel research international, EarlyView.Using a physical model, this study shows that vibration measurements reliably predict open eye size in steelmaking ladles, offering a practical alternative to visual monitoring. Vessel vibrations stabilize faster than the open eye, except at high frequencies near the bottom.

Mechanism Analysis and Multiphysics Validation of Lightning Attenuation in Constrained Space
IEEE Access, 2022 The problem of resistance reduction has always been the key and difficult point of lightning protection. However, the problem of reducing the grounding resistance efficiently has not been solved. A method is introduced in this paper to solve this problem

Lightning Impulse Voltage Stresses In Underground Cables
Journal of Physics: Conference Series, 2023 Abstract Underground power cables are crucial for transmission and distribution. Lightning can stress their insulation, but not directly. So, impulse cable testing is studied. This research examines the cable’s transient response to standard and non-standard lightning impulse voltage waveforms.

Trends in thunderstorm days, lightning activity, squalls and the environmental factors in Hong Kong
Weather, EarlyView.This study analyses trends in Hong Kong's convective weather using long‐term observer‐based and shorter‐term instrument‐based data. Annual thunderstorm days increased significantly by 1.9 days decade−1 in 1947–2024, notably in June–September, consistent with increasingly favourable warm‐season environments for thunderstorms.
