Metric Based Upscaling for Partial Differential Equations with a Continuum of Scales [PDF]

open access: yes, 2007
Numerical upscaling of problems with multiple scale structures have attracted increasing attention in recent years. In particular, problems with non-separable scales pose a great challenge to mathematical analysis and simulation.

Technological Advancements of Insoluble Dietary Fiber from Food By-Product Processing: A Review

open access: yesFoods
Insoluble dietary fibers (IDFs) represent one of the most promising candidates for novel food formulations, since they can be produced from a wide range of food by-products and wastes, have health benefits, and often enhance the rheology and stability of

Automated Symbolic Upscaling: 1. Model Generation for Extended Applicability Regimes

open access: yesWater Resources Research, 2023
In porous media theory, upscaling techniques are fundamental to deriving rigorous Darcy‐scale models for flow and reactive transport in subsurface systems.

A multi-level interface model for damaged masonry [PDF]

open access: yes, 2013
The aim of the present work is to propose a new micro-mechanical model in the context of the deductive approach used to derive interface models. This model, based on a previous study introduced previously by A. Rekik and F.

Carbon Nanotubes in Cement—A New Approach for Building Composites and Its Influence on Environmental Effect of Material

open access: yesMolecules
An addition of carbon nanostructures to cement paste is problematic due to the difficulties in obtaining homogenous mixtures. The paper reports on a more effective way of mixing carboxylated multi-walled carbon nanotubes (MWCNT-COOH) in cement pastes ...

Homogenization of two fluid flow in porous media

open access: yes, 2015
The macroscopic behavior of air and water in porous media is often approximated using Richards’ equation for the fluid saturation and pressure. This equation is parametrized by the hydraulic conductivity and water release curve.

Homogenization methods and macro-strength of composites [PDF]

open access: yes, 2001
A multi-phase periodic composite subjected to inhomogeneous shrinkage or temperature deformation and prescribed mechanical loads is considered. The asymptotic homogenisation is applied for calculation of homogenized macrostresses. A non-local approximate
