This paper concerns on the control problem of a class of nonlinear systems with input delay and dynamic uncertainties using multi-dimensional Taylor Network (MTN) control method. …
文化创意产业与区域经济之间存在一种相互促进、互为因果的耦合关系。运用动态耦合模型, 对青岛市2008—2019年的文化创意产业与区域经济的动态耦合程度进行实证分析。 结果表明,两者的综合水平均呈现曲折上升趋势,耦合度先上升后降低。 目前,青岛市正处于文化创意产业与区域经济的协调发展阶段,且整个系统将在未来一段时间内长期处于这一发展阶段, 同时,文化创意产业对 …
Hyperspectral image (HSI) contains rich spatial and spectral information, which has been widely used in resource exploration, ecological environment monitoring, land cover …
本文解析研究了外加移动载荷下定常流对非线性水弹性波的动力特性。假设流体是不可压缩的、无黏的,运动是无旋的,且所涉及波浪为非线性行进波。首先构建由水动力、弹性力、惯性力和外加载荷作用下的控制方程和非线性边界条件。随后借助同伦分析方法(HAM)求得收敛的近似解析解,着重研究外加载荷的移动速度对水弹波的影响。
Chinese poetry has been a favorite literary genre for thousands of years. Chinese ancient poetry is still being read and practiced, and many famous ancient Chinese poets are …
Changes in land cover will cause the changes in the climate and environmental characteristics, which has an important influence on the social economy and ecosystem. The main form …
实验室光谱仪是指通过光谱仪仅能获取光谱信号的光谱仪，高光谱相机可通过图像获取图像和光谱两种信息。在使用实验室光谱仪的条件下，针对不同温度、不同实验室的光谱仪、不同测量条件、不同地区间样品等因素的模型转移均已有研究报道，但是，针对高光谱相机与实验室光谱仪之间的模型转移问题的研究较少。本研究以青海 164 份土壤样品为例，获取其实验室光谱仪光谱数据和高光谱相机数 …
This paper proposes a nonlocal fractional peridynamic (FPD) model to characterize the nonlocality of physical processes or systems, based on analysis with the fractional derivative …
We investigate the problem of training an oil spill detection model with small data. Most existing machine-learning-based oil spill detection models rely heavily on big training …
Autumn Arctic sea ice has been declining since the beginning of the era of satellite sea ice observations. In this study, we examined the factors contributing to the decline of …
