超空泡射弹水下高速运动时，前端所受轴向扰动载荷非常大。考虑到扰动载荷的不确定性，有必要对超空泡射弹进行动力稳定性的可靠性分析。建立超空泡射弹截锥形结构的动力偏微分方程，并将其转化为二阶常微分Mathieu型参数振动方程，利用Bolotin方法对其动力稳定性进行数值计算，给出射弹结构动力稳定性的安全余量方程。分别分析了不同弹体杆径比、不同射弹航行速度以及不同弹体长度3种情况对超空泡射弹动力稳定性的影...
Nonparametric test for detecting change in distribution with panel data
nonparametric estimation panel data process
2011/6/15
This paper considers the problem of comparing two processes with
panel data. A nonparametric test is proposed for detecting a monotone
change in the link between the two process distributions. The t...

On blocks stably equivalent to a quantum complete intersection of dimension 9 characteristic abelian defect group conjecture
2011/1/17
Using a stable equivalence due to Rouquier, we prove that Brou´e’s abelian defect group conjecture holds for 3-blocks of defect 2 whose Brauer correspondent has a unique isomorphism class of sim...
Paley-Wiener Theorems with respect to the spectral parameter
Gelfand pairs Euclidean motion group Spherical Fourier transform

Indirect inference estimators (i.e., simulation-based minimum distance estimators) in a
parametric model that are based on auxiliary non-parametric maximum likelihood density
estimators are shown to...
