摘要:
文章以某连续刚构桥外观检测为背景,应用数学上的小波变换和正则性对采集到的信号进行分析,通过小波变换识别损伤位置。采用Lipschitz指数对桥梁损伤程度进行科学评估,实时提供桥梁健康状况,为桥梁正常运营提供可靠数据。研究表明,该桥最小损伤识别程度为3%;Lipschitz指数在单处损伤工况中较多处损伤工况要稳定,在多处损伤工况中,相互之间有一定的干扰,但是影响不大,足够满足工程应用的精度要求;选用不同的小波基对损伤评估也有一定的影响,鉴于本文研究建议选用MexH小波函数。

摘要:
针对基于深度卷积对抗式生成网络的图像生成方法存在训练过程稳定性亟待提高、图像生成质量效果欠佳等问题,提出一种将频谱规范化、自注意力机制与深度卷积对抗式生成网络结合的图像生成方法.在网络结构中,将频谱规范化的权重标准技术引入判别器,使判别器的参数矩阵满足Lipschitz约束,提高网络模型训练过程的稳定性;将自注意力机制引入生成器,使网络有目的地学习,得到质量更好的图像.实验结果证明,该方法相比目前的生成模型在CelebA、Cartooon数据集上能够有效地提高模型的收敛速度、训练稳定性和图像生成效果.

摘要:
In order to further improve the effectiveness of image processing,it is necessary that an efficient invariant representation is stable to deformation applied to images.This motivates the study of image representations defining an Euclidean metric stable to these deformation.This paper mainly focuses on two aspects.On the one hand,in this paper,two properties of expected scattering and averaged scattering,i.e.,Lipschitz continuity and translation invariance,are proved in detail.These properties support that excepted scattering and averaged scattering are invariant,stable and informative representations.On the other hand,the issue of texture classification based on expected scattering and averaged scattering has been analyzed respectively in this study.Energy features,which are based on expected scattering and averaged scattering,are calculated and used for classification.Experimental results show that starting with the seventh feature,the two approaches can achieve good performance in texture image classification.

摘要:
The purpose of this paper is to improve some famous theorems for contractive mapping from ρ(α + β) ∈ [0,1/s) to ρ(α + β) ∈ [0, 1) in ordered cone b-metric spaces over Banach algebras with coefficient s ≥ 1(ρ(x) is the spectral radius of the generalized Lipschitz constant x). Moreover, some similar improvements in ordered cone b-metric spaces are also obtained, which from α + β∈ [0,1/s) to α + β∈ [0, 1). Some examples are given to support that our new results are genuine improvements and generalizations.

摘要:
This paper studies the exponential attractor for a class of the Kirchhoff-type equations with strongly damped terms and source terms. The exponential attractor is also called the inertial fractal set, which is an intermediate step between global attractors and inertial manifolds. Obtaining a set that attracts all the trajectories of the dynamical system at an exponential rate by the methods of Eden A. Under appropriate assumptions, we firstly construct an invariantly compact set. Secondly, showing the solution semigroups of the Kirchhoff-type equations is squeezing and Lipschitz continuous. Finally, the finite fractal dimension of the exponential attractor is obtained.

摘要:
In this paper, we study the inertial manifolds for a class of the Kirchhoff-type equations with strongly damped terms and source terms. The inertial manifold is a finite dimensional invariant smooth manifold that contains the global attractor, attracting the solution orbits by the exponential rate. Under appropriate assumptions, we firstly exert the Hadamard’s graph transformation method to structure a graph norm of a Lipschitz continuous function, and then we prove the existence of the inertial manifold by showing that the spectral gap condition is true.
