Cross proper orthogonal decomposition

Physical Review Fluids, 2021
A new modal decomposition of fluid flows, labeled cross proper orthogonal decomposition (CPOD), is presented. CPOD modes are ranked by their contributions to the trace of the cross-covariance between flow fluctuations. An application of CPOD is presented for turbulent channel flow, with modes with maximal contribution to the Reynolds shear stress.

A New Look at Proper Orthogonal Decomposition

SIAM Journal on Numerical Analysis, 2003
Summary: We investigate some basic properties of the proper orthogonal decomposition (POD) method as it is applied to data compression and model reduction of finite dimensional nonlinear systems. First we provide an analysis of the errors involved in solving a nonlinear ODE initial value problem using a POD reduced order model.

Proper orthogonal decomposition of roof pressure

Journal of Wind Engineering and Industrial Aerodynamics, 1993
Abstract This paper illustrates application of the proper orthogonal decomposition in an investigation of the aerodynamic loading on a roof of a low-rise building. Pneumatically averaged pressure in a corner region of the roof, measured for concerning wind, was used in the analysis.

Kosambi and proper orthogonal decomposition

Resonance, 2011
In 1943 Kosambi published a paper titled ‘Statistics in function space’ in the Journal of the Indian Mathematical Society. This paper was the first to propose the technique of statistical analysis often called proper orthogonal decomposition today. This article describes the contents of that paper and Kosambi’s approach to the subject.
