Train Scheduling for Minimizing the Total Travel Time With a Skip-Stop Operation in Urban Rail Transit

IEEE Access, 2019
The skip-stop operating mode for urban rail transit systems defines three types of stations: A, B, and AB stations. In this strategy, all the trains stop at AB stations, and A (B) trains stop at only A (B) stations.

Experimental and numerical simulation analysis of the effects of water level fluctuation on subgrade [PDF]

Journal of Hebei University of Science and Technology
To address the limitation that current studies on subgrade seepage stability often simplify fills as homogeneous materials, this research investigated the effect of anisotropy in permeability by considering horizontal and vertical coefficients.

Railway Polygonized Wheel Detection Based on Numerical Time-Frequency Analysis of Axle-Box Acceleration

Applied Sciences, 2020
The increasing need for repairs of polygonized wheels on high-speed railways in China is becoming problematic. At high speeds, polygonized wheels cause abnormal vibrations at the wheel-rail interface that can be detected via axle-box accelerations.

Evaluating the relationships between the legal and illegal international wildlife trades

Conservation Letters, 2020
The international legal trade in wildlife can provide economic and other benefits, but when unsustainable can be a driver of population declines. This impact is magnified by the additional burden of illegal trade, yet how it covaries with legal trade ...
