In this article, the problem of event-triggered adaptive asymptotic tracking control (ATC) for stochastic nonlinear systems with unknown control directions (UCDs) and full state …
This paper is concerned with the tracking control for a class of switched nonlinear systems subject to prescribed performance. Firstly, a barrier function and a normalized function …
本文利用东京台风中心(Tokyo-Typhoon Center)发布的热带气旋(Tropical cyclone, TC) best-tracks资料，统计了1979—2019年经过黑潮关键区热带气旋的强度变化特征，并进一步分析了其中的物理机制。统计结果显示，黑潮对不同强度TC的加热效果不同，整体而言，TC外缘靠近黑潮关键区至TC中心进入关键区阶段，TC风速 …
Curved plasma channels have been proposed to guide intense lasers for various applications, such as x-ray laser emission, compact synchrotron radiation, and multistage laser …
通过使用天气研究与预报(Weather Research and Forecasting, WRF)模式对热带气旋(Tropical Cyclone, TC)个例“派比安”(1807)进行了一组数值试验，分析了东海黑潮暖舌对“派比安”强度的影响。研究结果表明，东海黑潮暖舌高海面温度(以下简称“海温”)导致TC区域内海气界面热通量显著增加，并造成TC边界层不稳 …
Abstract. Arctic Ocean simulations in 19 global ocean–sea-ice models participating in the Ocean Model Intercomparison Project (OMIP) of the Coupled Model Intercomparison Project …
The finite-time control of switched nonlinear systems subject to multiple objective constraints is investigated in this article. Firstly, with the aim of dealing with the major …
A recent study by Liu et al.(2020) suggested that due to the saturation of equatorially trapped planetary waves with different dynamical types, temporal periods, meridional and …
By virtue of the rapid development of ocean observation technologies, tens of petabytes of data archives have been recorded, among which, the largest portion are those derived from …
海洋次表层的热力结构对于海洋环流和全球气候变化具有重要的意义。提出一种新的融合高斯混合模型(gaussion mixture model, GMM)和 轻量级梯度提升机(light gradient boosting machine, LightGBM)算法的海洋次表层温度(ocean subsurface temperature, OST)反演 模型，利用 …
