A fault prediction method for catenary of high-speed rails based on meteorological conditions
Journal of Modern Transportation, 2019 Fault frequency of catenary is related to meteorological conditions. In this work, based on the historical data, catenary fault frequency and weather-related fault rate are introduced to analyse the correlation between catenary faults and meteorological ...

Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine
Wind Energy, Volume 29, Issue 6, June 2026.ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...

High Voltage, Volume 11, Issue 2, Page 370-384, April 2026.ABSTRACT As the ‘main blood vessel’ of the traction power supply system for high‐speed trains, the ‘wheel‐rail’ coupling grounding reflux system provides the vital channel to send traction current back to terrestrial substations; meanwhile, the rail track also plays a role in transmitting the train's occupancy signal to the control system. An insulated

Nanophotonics, Volume 15, Issue 5, 16 March 2026.This work presents a novel design strategy for active metasurfaces that actively switches OAM modes. The metasurface integrates VO2 within MIM meta‐atoms. Operating at 1500 nm, the designed platform enables large leaps in topological charge. For instance, the reflected beam can be switched from a topological charge of −1 in the insulating (M1) phase to

Experimental Evaluation of Prototype Seismic Retrofits for Precast Concrete Hollow‐Core Floors
Earthquake Spectra, Volume 42, Issue 1, February 2026.Existing hollow‐core floors are vulnerable to nonductile failure and potential collapse under earthquake loading. This study presents the development and experimental evaluation of novel comprehensive seismic retrofits for hollow‐core floors. These retrofits include a strongback‐type retrofit that provides an alternative gravity load path through steel
