Content-based image retrieval is an active area of research where image content is used to guide the search of relevant images from a dataset. Given a query image, the images in …
Aiming at switched nonlinear systems subject to input delay and saturation,a novel adaptive control strategy is proposed.Firstly,a compensation system is designed,which solves the …
In this paper,the stochastic nonlinear systems with full state constraints and dead-zone input are considered in the same framework for the first time,and a new adaptive controller …
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。
The Kuroshio Extension (KE) region in the Northwestern Pacific Ocean is one of the most eddy-energetic regions of the global ocean. In the past decades, much has been investigated …
In this paper, an observer-based adaptive Multi-dimensional Taylor network (MTN) controller is proposed for strictly feedback nonlinear systems with time-delay and unmeasurable …
In recent years, due to the rapid development of Chinese textile industry, the domestic demand for cotton increases sharply. Conversely, the cotton plantation area increasingly …
In this paper, we investigate the texture synthesis method generated from the hand-made sketches. In recent years, GANs have been vigorously studied in the field of image synthesis …
研究了漂浮在流体表面的超大型浮体的非线性水弹性响应。基于special Cosserat板理论将浮体简化为弹性Plotnikov and Toland板,在势流理论的框架下控制方程和反映水动力、惯性力和弹性力耦合作用的边界条件。运用同伦分析方法分析了一些重要参数对板的水弹性相应的影响,并比较了将浮体简化为非线性板和简化为线性板的差别。结果发现在较小板挠度情形 …
Nowadays, over 90 percent of the medical data comes from the medical image. People can reduce the medical faults in diagnoses by using computer to analyze and process these medical …
