    Federated deep reinforcement learning-based urban traffic signal optimal control by Mi Li, Xiaolong Pan, Chuhui Liu, Zirui Li

    Published 2025-04-01
    “…The proposed method improves the model generalization ability of different local models during global cross-region distributed joint training under the premise of ensuring information security and data privacy, solves the problem of non-independent and homogeneous distribution of environmental data faced by different agents in real intersection scenarios, and significantly accelerates the convergence speed of the model training phase. By reasonably designing the state, action and reward functions and determining the optimal values of several key parameters in the federated collaboration mechanism, the RL model could ensure high learning efficiency and fast convergence in the face of the gradual increase of road network size and the exponential increase of state and action space with the number of intersections. …”

    Influence of Polygon Wheel on Dynamic Performance of Meter-gauge Locomotive by Jingtao HU, Jiuhe YANG, Junjun DING, Zhaoxi LI, Fu LI

    Published 2019-03-01
    “…At last, the change trend of wheel-rail vertical forces was studied under the joint action of polygon wheel and track excitation. The results showed that due to the low running speed of the meter-gauge locomotive, the polygon wheel will form low frequency vibration which will increase the vibration response of the car body; the polygon wheel will greatly increase the wheel-rail vertical forces, but it has little effect on the derailment coefficient; the wave depth limit is inversely proportional to the running speed of the locomotive and the harmonic order; the track excitation will not cover the trend caused by polygon wheel, but it will greatly increase the wheel-rail vertical forces. …”
