On semi-modular subalgebras of Lie algebras over fields of arbitrary characteristic. [PDF]

open access: yes, 2008
This paper is a further contribution to the extensive study by a number of authors of the subalgebra lattice of a Lie algebra. It is shown that, in certain circumstances, including for all solvable algebras, for all restricted Lie algebras over ...

Characteristic polynomials of complex random matrix models [PDF]

open access: yes, 2002
We calculate the expectation value of an arbitrary product of characteristic polynomials of complex random matrices and their hermitian conjugates. Using the technique of orthogonal polynomials in the complex plane our result can be written in terms of

Wave length and celerity downstream from a hydraulic jump

open access: yesRBRH, 2019
The wave period, i. e., the time interval which corresponds to a complete oscillation, is an important parameter of wave characterization. It allows the estimation of other important wave characteristics such as the length and celerity.

含软弱土层场地地震动加速度反应谱特征周期调整方法

open access: yesDizhen xuebao
在分析场地条件对地震震害影响及国内外关于软弱土层对场地地震反应影响的基础上,采用实际含淤泥质土层场地资料,建立了12个含软弱土层的场地模型,在不同输入地震动水平下进行了场地地震反应一维等效线性化分析,讨论了软弱土层厚度和埋深对场地地震反应的影响。结果表明:随着软弱土层的埋深或厚度的增加,反应谱特征周期逐渐增大;输入地震动峰值增加,反应谱特征周期亦增大。继而依据软弱土层厚度、埋深及输入地震动强度对场地加速度反应谱特征周期的影响特征,提出了含软弱土层场地地震动加速度反应谱特征周期调整方法。
