Proper generalized decomposition of time-multiscale models [PDF]

open access: yes, 2011
Models encountered in computational mechanics could involve many time scales. When these time scales cannot be separated, one must solve the evolution model in the entire time interval by using the finest time step that the model implies.

Spatial Statistics for Screening Molecular Structures

open access: yesSmall, EarlyView.
Deep architectures for materials discovery demand vast training data and obscure the structure‐property link. This review shows how spatial statistics offer a physically grounded alternative: voxelized fields and two‐point correlations, compressed by principal component analysis, yield convex, interpretable descriptors. Lean surrogates then reach sub‐2%

PODNO: Proper Orthogonal Decomposition Neural Operators

open access: yesSIAM Journal on Scientific Computing
Abstract. In this paper, we introduce proper orthogonal decomposition neural operators (PODNO) for solving partial differential equations (PDEs) dominated by high-frequency components. Building on the structure of Fourier neural operators (FNO), PODNO replaces the Fourier transform with (inverse) orthonormal transforms derived from ...

MODEL REDUCTION METHODS IN OPTION PRICING [PDF]

open access: yes
In this work we introduce the Proper Orthogonal Decomposition (POD)approach to the valuation of contingent claims for one–dimensional price models.First, we present the POD in the context of an abstract Hilbert space and we givean application for the ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

open access: yessteel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Proper Orthogonal Decomposition for Parameter Estimation in Oscillating Biological Networks [PDF]

open access: yes, 2011
Proper orthogonal decomposition (POD) is frequently applied to estimate parameters of partial differential equations. This study examines the application of the POD method in estimating the parameters of an Ordinary Differential Equation (ODE) model of ...
