NONORTHOGONAL ANALYSIS OF VARIANCE USING A GENERALIZED conjugate-gradient algorithm
收藏 引用
JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION 1982年 第377期77卷 109-116页
作者: GOLUB, GH NASH, SG Professor Computer Science Department Stanford University Stanford CA 94305. Graduate student Computer Science Department Stanford University Stanford CA 94305
A method is developed that computes an exact nonorthogonal analysis of variance using cell means. The method is iterative and does not require that the nonorthogonal design matrix be stored or formed. At each stage in... 详细信息

Ab initio volume-dependent elastic and lattice dynamical properties of chalcopyrite CuAlSe2
收藏 引用
JOURNAL OF PHYSICS-CONDENSED MATTER 2006年 第4期18卷 1413-1425页
作者: Gürel, T Eryigit, R Abant Izzet Baysal Univ Dept Phys TR-14280 Bolu Turkey
We have performed an ab initio study of the volume dependence of elastic and lattice dynamical properties of chalcopyrite semiconductor CuAlSe2. The calculations have been carried out within the local density function... 详细信息

Accelerating and parallelizing minimizations in ensemble and deterministic variational assimilations
收藏 引用
QUARTERLY JOURNAL OF THE ROYAL METEOROLOGICAL SOCIETY 2012年 第667期138卷 1599-1610页
作者: Desroziers, Gerald Berre, Loik Meteo France CNRS CNRM GAME F-31057 Toulouse France
The specification of a correct background-error covariance matrix is a key issue in data assimilation schemes. The Ensemble Kalman Filter (EnKF) aims at providing simulations of analysis and background errors and then... 详细信息

Ab initio thermodynamics of MgSiO3 perovskite at high pressures and temperatures -: art. no. 124501
收藏 引用
JOURNAL OF CHEMICAL PHYSICS 2005年 第12期122卷 4501-4506页
作者: Oganov, AR Price, GD ETH Honggerberg Dept Mat Crystallog Lab CH-8093 Zurich Switzerland UCL Dept Earth Sci London WC1E 6BT England
Using quantum-mechanical simulations based on density-functional perturbation theory, we address the problem of stability of MgSiO3 perovskite to decomposition into MgO and SiO2 at pressures and temperatures of the Ea... 详细信息

A stabilized finite element method for stochastic incompressible Navier-Stokes equations
收藏 引用
INTERNATIONAL JOURNAL OF COMPUTER MATHEMATICS 2012年 第18期89卷 2576-2602页
作者: El-Amrani, Mofdi Seaid, Mohammed Zahri, Mostafa Univ Rey Juan Carlos Dept Matemat Aplicada Madrid 28933 Spain Univ Durham Sch Engn & Comp Sci Durham DH1 3LE England Univ Taibah Dept Math Al Madinah Saudi Arabia
The major emphasis of this work is the development of a stabilized finite element method for solving incompressible Navier-Stokes equations with stochastic input data. The polynomial chaos expansion is used to represe... 详细信息
