An Analysis of Open-Ended Coaxial Probe Sensitivity to Heterogeneous Media [PDF]
Sensors, 2020 Open-ended coaxial probe spectroscopy is commonly used to determine the dielectric permittivity of biological tissues. However, heterogeneities in the probe sensing region can limit measurement precision and reproducibility.

Diffusion-limited reactions in dynamic heterogeneous media [PDF]
Nature Communications, 2018 “Diffusing diffusivity” concept has been recently put forward to account for rapid structural rearrangements in soft matter and biological systems. Here the authors propose a general mathematical framework to compute the distribution of first-passage ...

Nonlinear Poisson equation for heterogeneous media. [PDF]
Biophys J, 2012 The Poisson equation is a widely accepted model for electrostatic analysis. However, the Poisson equation is derived based on electric polarizations in a linear, isotropic, and homogeneous dielectric medium. This article introduces a nonlinear Poisson equation to take into consideration of hyperpolarization effects due to intensive charges and possible

A Micromechanical Model of Additively Manufactured Aluminum Alloys [PDF]
EPJ Web of Conferences, 2019 A micromechanical model is developed to predict the deformation behavior of additively manufactured aluminum alloys. Three-dimensional models of grain structures typical for different microregions of the melt pool are generated by the step-by-step ...

Fractal heterogeneous media [PDF]
Physical Review E, 2010 A method is proposed for generating compact fractal disordered media, by generalizing the random midpoint displacement algorithm. The obtained structures are invasive stochastic fractals, with the Hurst exponent varying as a continuous parameter, as opposed to lacunar deterministic fractals, such as the Menger sponge. By employing the Detrending Moving

PRELIMINARY INVESTIGATIONS OF TRANSPORT IN HETEROGENEOUS RANDOM MEDIA [PDF]
EPJ Web of Conferences, 2021 Random media emerge in several applications in reactor physics and safety analysis. Most often, models of stochastic media assume spatial homogeneity, whereas real-world complex materials, such as fuel chunks resulting from core degradation, typically ...

Compression effects in heterogeneous media [PDF]
Journal de l’École polytechnique — Mathématiques, 2019 We study in this paper compression effects in heterogeneous media with maximal packing constraint. Starting from compressible Brinkman equations, where maximal packing is encoded in a singular pressure and a singular bulk viscosity, we show that the global weak solutions converge (up to a subsequence) to global weak solutions of the two-phase ...
