Spectral proper transformation and application to gust response prediction of structures

open access: yesVietnam Journal of Mechanics, 2007
Random turbulent loading on engineering structures which immersed in the atmospheric turbulent flow is often represented as the multi-dimensional and/ or multivariate Gaussian random loading processes. Gust response prediction, however, usually burdens a

A reduced Galerkin finite element formulation based on proper orthogonal decomposition for the generalized KDV-RLW-Rosenau equation

open access: yesJournal of Inequalities and Applications, 2023
This paper investigates reduced-order modeling of the Korteweg de Vries regularized long-wave Rosenau (KdV-RLW-Rosenau) equation using semi- and fully-discrete B-spline Galerkin approximations. The approach involves the application of a proper orthogonal

The proper generalized decomposition for the simulation of delamination using cohesive zone model [PDF]

open access: yes, 2014
The use of cohesive zone models is an efficient way to treat the damage, especially when the crack path is known a priori. This is the case in the modeling of delamination in composite laminates.

An overview of the proper generalized decomposition with applications in computational rheology [PDF]

open access: yes, 2014
We review the foundations and applications of the proper generalized decomposition (PGD), a powerful model reduction technique that computes a priori by means of successive enrichment a separated representation of the unknown field.

On the deterministic solution of multidimensional parametric models using the Proper Generalized Decomposition [PDF]

open access: yes, 2010
This paper focuses on the efficient solution of models defined in high dimensional spaces. Those models involve numerous numerical challenges because of their associated curse of dimensionality.

Domain decomposition involving subdomain separable space representations for solving parametric problems in complex geometries

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2022
A domain decomposition technique combined with an enhanced geometry mapping based on the use of NURBS is considered for solving parametrized models in complex geometries (non simply connected) within the so-called proper generalized decomposition (PGD ...

PGD based meta modelling of a lithium-ion battery for real time prediction

open access: yesFrontiers in Materials, 2023
Despite the existence of computationally efficient tools, the effort for parametric investigations is currently high in industry. In this paper, within the context of Li-Ion batteries, an efficient meta-modelling approach based on the Proper Generalized ...

A subsystem-independent generalization of entanglement [PDF]

open access: yes, 2003
We introduce a generalization of entanglement based on the idea that entanglement is relative to a distinguished subspace of observables rather than a distinguished subsystem decomposition. A pure quantum state is entangled relative to such a subspace if

A Multidimensional Data-Driven Sparse Identification Technique: The Sparse Proper Generalized Decomposition

open access: yesComplexity, 2018
Sparse model identification by means of data is especially cumbersome if the sought dynamics live in a high dimensional space. This usually involves the need for large amount of data, unfeasible in such a high dimensional settings.
