...Biswarup Bhattacharyya; Eric Jacquelin; Denis Brizard A proper orthogonal decomposition (POD)-based polynomial chaos expansion (PCE) is utilized in this article for the uncertainty quantification (UQ) of an impact dynamic oscillator. The time-dependent nonsmooth behavior and the uncertainties...

... locations. The differences between the vertical displacement responses of a vehicle passing the damaged bridge and the healthy bridge are sampled and called the relative displacement response vector of the vehicle. The proper orthogonal decomposition (POD) is utilized to decompose the relative displacement...

...Timothy C. Allison; A. Keith Miller; Daniel J. Inman Two general linear time-varying system identification methods for multiple-input multiple-output systems are proposed based on the proper orthogonal decomposition (POD). The method applies the POD to express response data for linear or nonlinear...

...U. Iemma; M. Diez; L. Morino An extension of the Karhunen-Loève decomposition (KLD) specifically aimed at the evaluation of the natural modes of n -dimensional structures ( n = 1 , 2 , 3 ) having nonhomogeneous density is presented. The KLD (also known as proper orthogonal decomposition...
