全球平均海平面上升的瞬时速率
海平面上升 瞬时速率 海水比容 海水质量
2019/1/8
在确定海平面上升速率时,传统方法是利用最小二乘拟合获取特定时间段内的平均速率.事实上,由于海平面是一种非稳态变化,其速率随着时间变化.本文使用集成经验模态分解获取海平面变化在2002-2014年间的非线性趋势,然后通过三次样条函数平滑拟合非线性趋势得到连续的一阶导数,即为海平面变化的瞬时速率.结果表明,全球平均海平面的瞬时速率先降后升:从2002的2.7 mm·a-1缓慢下降至2010年的2.5 ...
微观结构对复合材料的宏观力学性能具有至关重要的影响, 通过合理设计复合材料微观结构可以得到期望的宏观性能. 均质化方法作为一种有效的设计方法, 它从微观结构的角度出发, 利用均匀化的概念, 实现了对复合材料宏观力学性能的预测和设计. 而当考虑非线性因素, 均质化的实现就非常困难. 本文利用双渐近展开方法, 将位移按照宏观位移和微观位移展开, 推导了非线性弹性均质化方程. 通过直接迭代法, 对非线性...

Semidefinite programming relaxations of non-convex problems in control and combinatorial optimization
Applications of semidefinite programming combinatorial optimization quadratic semi-definite programming bilinear matrix inequality
2015/8/11
We point out some connections between applications of semidefinite programming in control and in combinatorial optimization. In both fields semidefinite programs arise as convex relaxations of NP-hard...

2014/12/8
In this thesis we study the central limit theorem (CLT) for nonuniformly hy- perbolic dynamical systems. We examine cases in which polynomial decay of cor- relations leads to a CLT with a non-standard...
