Tracking error analysis for multi-train systems under velocity constraints and parameter uncertainties

Yi Huang, Zhiyong Chen, Zhixin Zhang, Zuguo Chen et autres

This paper investigates the cooperative tracking error for multi-train systems subject to velocity constraints and time-varying resistance parameter uncertainties. A distributed tracking control algorithm, utilizing only relative position measurements between adjacent trains, is proposed to enable all trains to track a desired …

DualPop: User Popularity Preference Aware Debiasing Recommendation

Zhuoming Li, Youshen Chi, Yuliang Shi, Jihu Wang et autres

Recommender systems usually suffer from popularity biases, where a few popular items are over-recommended, while most long-tail items struggle to gain exposure. Prior research focused on eliminating the influence of popularity to suppress popular items and enhance the recommendation of long-tail items. …

Simulation of Complex Hydraulic Fracture Propagation in Shale with Interlayers

Zhiyong Chen, Hui Xiao, Bo Xu, Guangda Gao et autres

Shale gas, as an unconventional resource, requires hydraulic fracturing to create complex fracture networks due to its low porosity and permeability. However, the presence of interlayers significantly affects fracture propagation, leading to highly complex fracture morphologies. This study focuses on the interbedded …

A Distributed Braking Scheme for Heavy-Haul Trains Using Coupler Force Compensation

J Q Zhang, Zhiyong Chen, Ge Guo

In this paper, a novel distributed braking scheme is proposed for automatic heavy-haul trains equipped with an electronically controlled pneumatic (ECP) braking system. The scheme consists of a coupler force compensator and a cooperative controller. The compensator is designed to counteract the …

Multi-shape enhancement pyramid network for real-time semantic segmentation

Zhiyong Chen, Zhao Yang, Peng Liu, Feng Wang et autres

Based on powerful convolutional neural networks (CNNs) and complex model structures, semantic segmentation achieves good segmentation accuracy, but its slow inference speed limits its use in practical applications, such as autonomous driving and medical diagnosis. Thus, real-time semantic segmentation receives increasing attention. …

ModelWisdom: An Integrated Toolkit for TLA$$^{+}$$ Model Visualization, Digest and Repair (Short Tool Paper)

Zhiyong Chen, Jialun Cao, Chang Xu, S C Cheung

Abstract Model checking in TLA+ provides strong correctness guarantees, yet practitioners continue to face significant challenges in interpreting counterexamples, understanding large state-transition graphs, and repairing faulty models. These difficulties stem from the limited explainability of raw model-checker output and the substantial manual …
