IEEE Control Systems Magazine 2007年 第4期27卷 89-105页
作者: Paley, Derek A. Leonard, Naomi Ehrich Sepulchre, Rodolphe Grünbaum, Daniel Parrish, Julia K. Princeton University Department of Mechanical and Aerospace Engineering Princeton NJ 08544 United States Department of Mechanical and Aerospace Engineering Program in Applied and Computational Mathematics Princeton University Princeton NJ 08544 United States Department Electrical Engineering and Computer Science University of Liège Liège Belgium School of Oceanography Department of Biology University of Washington Seattle WA United States Biology Department School of Aquatic and Fishery Sciences University of Washington Seattle WA United States
A description of the so called "particles with coupled oscillator dynamics" (PCOD) is presented which is used to model, analyze and synthesize collective motion. An oscillator model with spatial dynamics is ... 详细信息

作者: Botchev, Mike A. Golub, Gene H. Department of Applied Mathematics University of Twente P.O. Box 217 7500 AE Enschede Netherlands Scientific Computing and Computational Mathematics Program Stanford University Stanford CA 94305-9025
For the iterative solution of saddle point problems, a nonsymmetric preconditioner is studied which, with respect to the upper-left block of the system matrix, can be seen as a variant of SSOR. An idealized situation ... 详细信息

作者: Benedetto, John J. Powell, Alexander M. Yilmaz, Özgür Department of Mathematics University of Maryland College Park MD 20742 United States Program in Applied and Computational Mathematics Princeton University Princeton NJ 08544 United States Department of Mathematics University of British Columbia Vancouver BC V6T 1Z2 Canada
The second-order Sigma-Delta (ΣΔ) scheme with linear quantization rule is analyzed for quantizing finite unit-norm tight frame expansions for Rd. Approximation error estimates are derived, and it is shown that for c... 详细信息

Coarse Graining the Dynamics of Coupled Oscillators
收藏 引用
Physical Review Letters 2006年 第14期96卷 144101-144101页
作者: Sung Joon Moon R. Ghanem I. G. Kevrekidis Department of Chemical Engineering & Program in Applied and Computational Mathematics (PACM) Princeton University Princeton New Jersey 08544 USA Department of Civil Engineering University of Southern California Los Angeles California 90089 USA
We present an equation-free computational approach to the study of the coarse-grained dynamics of finite assemblies of nonidentical coupled oscillators at and near full synchronization. We use coarse-grained observabl... 详细信息

Coarse molecular-dynamics determination of the onset of structural transitions: Melting of crystalline solids
收藏 引用
Physical Review B 2006年 第13期74卷 132201-132201页
作者: Miguel A. Amat Ioannis G. Kevrekidis Dimitrios Maroudas Department of Chemical Engineering University of Massachusetts Amherst Massachusetts 01003 USA Department of Chemical Engineering and Program in Applied and Computational Mathematics Princeton University Princeton New Jersey 08544 USA
Using a coarse molecular-dynamics (CMD) approach with an appropriate choice of coarse variable (order parameter), we map the underlying effective free-energy landscape for the melting of a crystalline solid. Implement...
