Variational data assimilation for a nonlinear hydraulic model
收藏 引用
applied MATHEMATICAL MODELLING 1996年 第9期20卷 675-682页
作者: Chertok, DL Lardner, RW Applied and Computational Mathematics Program Simon Fraser University Burnaby British Columbia Canada
A method is developed for the optimal estimation of the parameters in a fully nonlinear model of flow in a channel. The data assimilated consist of values of the water surface elevation during a given interval. The me... 详细信息

Large-scale statistics of the Kuramoto-Sivashinsky equation: A wavelet-based approach
收藏 引用
Physical Review E 1996年 第1期54卷 224-224页
作者: J. Elezgaray G. Berkooz P. Holmes Program in Applied and Computational Mathematics and Department of Mechanical and Aerospace Engineering Princeton University New Jersey 08544
We show that the statistical properties of the large scales of the Kuramoto-Sivashinsky equation in the extended system limit can be understood in terms of the dynamical behavior of the same equation in a small finite...

Horseshoes and nonintegrability in the restricted case of a spinless axisymmetric rigid body in a central gravitational field
收藏 引用
CELESTIAL MECHANICS & DYNAMICAL ASTRONOMY 1995年 第1期63卷 59-79页
作者: Balan, R Program in Applied and Computational Mathematics Princeton University Princeton USA
The purpose of this paper is to study the motion of a spinless axisymmetric rigid body in a Newtonian field when we suppose the motion of the center of mass of the rigid body is on a Keplerian orbit. In this case the ... 详细信息

Optimal estimation of Eddy viscosity and friction coefficients for a Quasi‐three‐dimensional numerical tidal model
收藏 引用
Atmosphere 1995年 第3期33卷 581-611页
作者: R.W. Lardner[a] & Y. Song[a][b]* [a] Applied and Computational Mathematics Program Simon Fraser University Burnaby B.C. V5A 1S6 Canada [b] Institute of Marine and Coastal Sciences Rutgers University New Brunswick NJ
It is shown that the parameters in a quasi‐three‐dimensional numerical tidal model can be estimated accurately by assimilation of data from current meters and tide gauges. The tidal model considered is a semi‐linea...
