Aerodynamic noise from a train pantograph

, 2014
Many studies have shown that when the speed of high speed trains exceeds around 300km/h, aerodynamic noise becomes the most significant noise source. The pantograph, or current collector, is mounted on the top of the train and is therefore not shielded ...

Rapid Coupling Prediction for Compact GNSS Arrays via Graph Transformer

Electronics Letters, Volume 61, Issue 1, January/December 2025.
The design of compact GNSS antenna arrays requires rapid evaluation of mutual coupling effects, which conventional full‐wave simulations fail to deliver due to excessive computational costs. This letter proposes a graph transformer model that predicts coupling matrices in real time. By hybridizing the local perception of graph isomorphism network (GIN)
