The influence of track geometry irregularities on rolling contact fatigue
, 2012 Optimised maintenance of railway tracks requires knowledge of how a deteriorated track geometry will affect subsequent damage of the track. In this study the influence on rolling contact fatigue (RCF) is investigated through numerical simula- tions.

Correlation analysis method of track irregularity indexes
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Research on the correlation analysis method of track irregularity indexes has an important guiding role in selecting targeted maintenance decision-making indexes and guiding maintenance decision making related to track irregularity state. In this study, the track irregularity index structures and track quality index were used to

Advanced Functional Materials, EarlyView.A bilayer “Anchor‐and‐Seal” passivation strategy using EDAI2 and 4MeO‐PEAI effectively mitigates surface defects in vacuum‐processed perovskite films through synergistic hydrogen bonding and Lewis base coordination. This approach optimizes interfacial energy alignment and suppresses non‐radiative recombination, enabling vacuum‐deposited p‐i‐n ...
