Geometry dependent Reduced-Order Models for the computation of homogenized transfer properties in porous Media, Part II -Electrical Double Layer effects

A Reduced-Order Model (ROM) based on Proper Orthogonal Decomposition (POD) is proposed to solve fastly the strongly nonlinear Elementary Cell Problem derived from the Periodic Homogenization of the Nernst-Planck-Poisson-Boltzmann equations. In…

Effect of MICP treatment on the mechanical properties of clay soils

The presence of drying cracks can significantly affect soil hydromechanical behavior, which has effects on soil performance in civil engineering. One innovative approach that has received much interest in the last decade is using microbially induced…

Advanced FE-based multimodal correlation analyses for the characterization of woven composite

This paper presents a comprehensive characterization of a woven glass fiber composite sample with two notches in the gauge area subjected to cyclic tension using an Arcan fixture. An advanced optical setup was developed, comprising two visible light…

Simulation-guided PGD-Stereocorrelation for hybrid testing

Hybrid testing aims to evaluate the dynamics of a large scale structure from which an isolated part is experimentally tested, while the rest is simulated in the control loop for imposing earthquake-induced motions at boundaries. One of these tests,…

Strict Discretization Error Bounds on Quantities of Interest in Transient Dynamics

ABSTRACT This work proposes a guaranteed error estimator for linear transient elastodynamics, accounting for both time and space discretization errors. The key lies in the definition of a novel dynamic constitutive relation error formulation, which…

Pipeline for Semantic Segmentation of Large Railway Point Clouds

This paper presents a novel deep-learning pipeline to segment large railway datasets with minimal manual annotation, notoriously time consuming. The pipeline adapts DINOv2 [11] for labeling point clouds, with tailored self-distillation pre-training…
