The interfacial Dzyaloshinskii-Moriya interaction (iDMI) was observed in the bilayer consisting of a heavy metal and a ferromagnetic insulator such as Pt vertical bar Tm3Fe5O12 …
In order to improve the reliability of moving objects detection and tracking, this paper presents a method for moving object real-time detection and tracking based on Vibe and …
The current main stream researches on state fragility are mostly focusing on the social, political, ecological and economic aspects. However, as one of the most critical issues on …
In this paper, multi-dimensional Taylor network (MTN) tracking control scheme is proposed for a class of stochastic nonlinear systems with unknown input dead-zone. The …
本文研究了在剪切流和深水行进波的共同作用下超大型海洋浮体(VLFS)的非线性水弹性响应问题。针对垂向速度呈指数分布的有旋剪切流情形,提出引入流函数构建物理模型的方法,并运用不依赖于任何物理小参数的同伦分析方法(HAM)求得收敛的近似解析解。最后利用计算结果详细讨论了几种重要物理量对板的非线性水弹性响应的影响,我们发现指数剪切流与行进波同向时,涡量越大板的波形 …
The majority of studies on texture analysis focus on classification and generation, and few works concern perceptual similarity between textures, which is one of the fundamental …
Effects of underlying uniform current on the nonlinear hydroelastic waves generated due to an infinite floating plate are studied analytically, under the hypotheses that the fluid …
本文解析研宄了在均匀流作用下漂浮在流体表面的无限长薄板的非线性水弹性响应。 在势流理论框架下， 假设流体是无粘的、 不可压缩的，运动是无旋的。 我们以拉普拉斯方程为控制方程， 在板同场中构建非线性动力学和运动学边界条件。借助同伦分析方法求得速一度势、 板挠度的收敛近似解析解； 并深入考査了些重要物理量对非线性水弹动力特性的影响。其中发现薄板的非线 …
The Arctic sea ice minimum records appeared in the Septembers of 2007 and 2012, followed by high snow cover areas in the Northern Hemisphere winters. The snow cover distributions …
In this paper, we analyzed the correlation relationship among PM2.5 from other five Air Quality Indices(AQIs) based on the grey relational degree, and built a multivariate …
