In a model plankton ecosystem containing phytoplankton and zooplankton, the later usually avoids toxic phytoplankton and prefers nontoxic species by modulating its grazing rate. …
For the tracking control problem of a class of switched nonlinear systems with input delay, this article proposes an adaptive tracking control scheme based on multi-dimensional …
Fine particle (PM2.5) mass concentration and relative humidity (RH) are the primary factors influencing atmospheric visibility. There are some studies focused on the complex, …
In this article, the problem of adaptive multi-dimensional Taylor network control for strict-feedback nonlinear stochastic systems with time-delay is investigated. To overcome the …
Subsurface chlorophyll maxima (SCMs), commonly occurring beneath the surface mixed layer in coastal seas and open oceans, account for main changes in depth-integrated primary …
研究一类具有有限时间输出约束的切换非线性时滞系统的控制器设计问题.为了在有限时间将输出跟踪误差限制在预定边界内,引入一种改进的有限时间性能函数(FTPF).在控制器的设计过程中,利用障碍Lyapunov函数来解决输出约束问题.然后,将多维泰勒网(MTN)的逼近特性与自适应反步技术相结合,提出一种新的自适应MTN控制方法.在该方法中,通过设计 …
本工作选取多种经典相关系数进行了对比研究,如Pearson相关系数、Spearman相关系数、距离相关系数、最大信息系数及HHG相关系数。具体地,在不同数据规模及噪声水平下,对线性、非线性单调、非单调、非函数等不同类型变量的相关性分别进行研究,得到各相关系数的统计功效。通过分析发现,Pearson相关系数、Spearman相关系数更适合衡量线性、非线性单调相 …
This paper reviews the development of the global carbon cycle processes in the two generations of the First Institute of Oceanography-Earth System Model (FIO-ESM v1.0 and v2.0). …
As a prime circulation system, the western Pacific subtropical high (WPSH) significantly impacts tropical cyclone (TC) activities over the western North Pacific (WNP), especially …
This study investigates how Eastern Pacific (EP) and Central Pacific (CP) El Niño events differentially impact the interannual variability of diurnal sea surface temperature (dSST) …
