Reduced Modeling of Unknown Trajectories [PDF]
Archives of Computational Methods in Engineering, 2017 This paper deals with model order reduction of parametrical dynamical systems. We consider the specific setup where the distribution of the system's trajectories is unknown but the following two sources of information are available: \textit{(i)} some "rough" prior knowledge on the system's realisations; \textit{(ii)} a set of "incomplete" observations ...

Revista Brasileira de Engenharia Agrícola e Ambiental, 2001 Na drenagem agrícola, os drenos são instalados, geralmente, sobre a camada impermeável ou a certa distância acima desta. A profundidade de instalação dos drenos e a do perfil, a condutividade hidráulica e a porosidade drenável são parâmetros de ...

Analysis of planes within reduced micromorphic model
Scientific Reports, 2021 A plane within reduced micromorphic model subjected to external static load is studied using the finite element method. The reduced micromorphic model is a generalized continuum theory which can be used to capture the interaction of the microstructure ...

An Artificial Compression Reduced Order Model [PDF]
SIAM Journal on Numerical Analysis, 2020 We propose a novel artificial compression, reduced order model (AC-ROM) for the numerical simulation of viscous incompressible fluid flows. The new AC-ROM provides approximations not only for velocity, but also for pressure, which is needed to calculate forces on bodies in the flow and to connect the simulation parameters with pressure data. The new AC-

Reduced Models of Point Vortex Systems [PDF]
Entropy, 2018 Nonequilibrium statistical models of point vortex systems are constructed using an optimal closure method, and these models are employed to approximate the relaxation toward equilibrium of systems governed by the two-dimensional Euler equations, as well as the quasi-geostrophic equations for either single-layer or two-layer flows.

Symmetry and reduced symmetry in model checking [PDF]
ACM Transactions on Programming Languages and Systems, 2001 Symmetry reduction methods exploit symmetry in a system in order to efficiently verify its temporal properties. Two problems may prevent the use of symmetry reduction in practice: (1) the property to be checked may distinguish symmetric states and hence not be preserved by the symmetry, and (2) the system may exhibit little or no symmetry.

Error estimation of a proper orthogonal decomposition reduced model of a permanent magnet synchronous machine [PDF]
, 2014 Model order reduction methods, like the proper orthogonal decomposition (POD), enable to reduce dramatically the size of a finite element (FE) model.
