Approximate Deconvolution Reduced Order Modeling
This paper proposes a large eddy simulation reduced order model(LES-ROM) framework for the numerical simulation of realistic flows. In this LES-ROM framework, the proper orthogonal decomposition(POD) is used to define the ...
Structured noncommutative multidimensional linear systems
(Siam Publications, 2005)
We introduce a class of multidimensional linear systems with evolution along a free semigroup. The transfer function for such a system is a formal power series in noncommuting indeterminates. Standard system-theoretic ...
A Linear Algorithm for Ambient Seismic Noise Double Beamforming Without Crosscorrelations
Geoscientists and engineers are increasingly using denser arrays for continuous seismic monitoring, and often turning to ambient seismic noise interferometry for low-cost near-surface imaging. While ambient noise interferometry ...

Chern-Schwartz-MacPherson classes for Schubert cells in flag manifolds
We obtain an algorithm computing the Chern-Schwartz-MacPherson (CSM) classes of Schubert cells in a generalized flag manifold G/B. In analogy to how the ordinary divided difference operators act on Schubert classes, each ...
