Study on the improvement of semi-Hertzian wheel/rail contact algorithms

引用

Journal of Traffic and Transportation Engineering(English Edition) 2025年第01期 23-33页

作者： Yaru Liang Qunsheng Wang Jing Zeng bin zhu Rancheng Mao State Key Laboratory of Rail Transit Vehicle System Southwest Jiaotong University Urban Rail Transit Center of CARS China Academy of Railway Sciences Corporation Limited

The normal stress distribution of the contact patch is the base for wheel/rail dynamic analysis as well as the wheel wear calculation. When the wheel polygonalization appears on the worn-type wheel tread of the high-speed trains, the lateral and longitudinal relative wheel/rail curvature around the contact patch will vary with the change of wheel circumferential position. In such a case, the commonly used Hertzian contact method cannot meet the calculation precision, while even the non-Hertzian method has relatively high precision, but its calculation efficiency cannot meet the demand of engineering application. A non-Hertzian method was introduced to analyze the influence of the wheel polygonalization on the contact patch. By studying the shape and the pressure distribution of the contact patches at different contact positions, it is found that when the wavelength of the wheel polygonalization is larger than 65 mm, the results of the improved semiHertzian method can agree well with the non-Hertzian method with reasonable computing time. Besides, to ensure that the calculation result can meet the accuracy requirement when the wheelset yaw motion occurs, the trace method is used to improve the semi-Hertzian method and verified by the contact method.

Exploratory Research on Defense against Natural Adversarial Examples in Image Classification

引用

Computers, Materials & Continua 2025年第2期82卷 1947-1968页

作者： Yaoxuan zhu Hua Yang bin zhu The State Key Laboratory of Pulsed Power Laser Technology National University of Defense TechnologyHefei230037China

The emergence of adversarial examples has revealed the inadequacies in the robustness of image classification models based on Convolutional Neural Networks (CNNs). Particularly in recent years, the discovery of natural adversarial examples has posed significant challenges, as traditional defense methods against adversarial attacks have proven to be largely ineffective against these natural adversarial examples. This paper explores defenses against these natural adversarial examples from three perspectives: adversarial examples, model architecture, and dataset. First, it employs Class Activation Mapping (CAM) to visualize how models classify natural adversarial examples, identifying several typical attack patterns. Next, various common CNN models are analyzed to evaluate their susceptibility to these attacks, revealing that different architectures exhibit varying defensive capabilities. The study finds that as the depth of a network increases, its defenses against natural adversarial examples strengthen. Lastly, Finally, the impact of dataset class distribution on the defense capability of models is examined, focusing on two aspects: the number of classes in the training set and the number of predicted classes. This study investigates how these factors influence the model’s ability to defend against natural adversarial examples. Results indicate that reducing the number of training classes enhances the model’s defense against natural adversarial examples. Additionally, under a fixed number of training classes, some CNN models show an optimal range of predicted classes for achieving the best defense performance against these adversarial examples.

Probing the flavor-specific scalar mediator for the muon(g-2)deviation, the proton radius puzzle and the light dark matter production

引用

Science China(Physics,Mechanics & Astronomy) 2022年第3期65卷 39-48页

作者： bin zhu Xuewen Liu Department of Physics Yantai UniversityYantai 264005China

Flavor-specific scalar bosons exist in various Standard Model extensions and couple to a single generation of fermions via a global flavor symmetry breaking mechanism. Given this strategy, we propose a Me V flavor-specific scalar model in dimension-5 operator series, which explains the muon g-2 anomaly and proton radius puzzle by coupling with the muon and down-quark at the same time. The framework is consistent with the null result of high-intensity searches. Specifically, the supernova constraints for muon couplings become weakened by including the contribution of down-quark interaction. The parameter space for explaining muon g-2 discrepancy is available when 10% energy deposition is required in the energy explosion process in the supernova,but this is ruled out by the 1% energy deposition requirement. We also investigate the searches for mediator and dark matter and the resulting constraints on viable parameter space such as nuclear physics constraints, direct detection for light boosted dark matter, and possible CMB constraints. When compared with conventional dark matter production, light dark matter production has two additional modifications: bound state formation and early kinetic equilibrium decoupling. We are now looking into the implications of these effects on the relic density of light dark matter.

Applications of BGP-reflection functors: isomorphisms of cluster algebras

引用

Science China Mathematics 2006年第12期49卷 1839-1854页

作者： zhu bin Department of Mathematical Sciences Tsinghua UniversityBeijing 100084Chinae

Given a symmetrizable generalized Cartan matrix A, for any index k, one can define an automorphism associated with A, of the field Q(u1,…, un) of rational functions of n independent indeterminates u1,…,*** is an isomorphism between two cluster algebras associated to the matrix A (see sec. 4 for the precise meaning). When A is of finite type, these isomorphisms behave nicely; they are compatible with the BGP-reflection functors of cluster categories defined in a previous work if we identify the indecomposable objects in the categories with cluster variables of the corresponding cluster algebras, and they are also compatible with the 'truncated simple reflections' defined by Fomin-Zelevinsky. Using the construction of preprojective or preinjective modules of hereditary algebras by DIab-Ringel and the Coxeter automorphisms (i.e. a product of these isomorphisms), we construct infinitely many cluster variables for cluster algebras of infinite type and all cluster variables for finite types.
