Radial solutions for p‐Laplacian Neumann problems with gradient dependence

Mathematische Nachrichten, 2022
We study the radial solutions of the p‐Laplacian Neumann problem with gradient dependence of the type −Δpu=f(|x|,u,|∇u|)inΩ,∂u∂n=0on∂Ω,$$\begin{equation*} {\hspace*{8pc}\left\lbrace \def\eqcellsep{&}\begin{array}{l}-\Delta _{p}u=f(|x|,u,|\nabla u|)\quad \

Temperature gradient dependence on electrical tree in epoxy resin with harmonic superimposed DC voltage

IEEE transactions on dielectrics and electrical insulation, 2020
Transient superimposed voltage, which is accompanied by a temperature gradient caused by Joule heat, can threaten the insulation safety of high-voltage direct current (HVDC) cable terminations.

A sub-supersolution approach for Neumann boundary value problems with gradient dependence

, 2020
Existence and location of solutions to a Neumann problem driven by an nonhomogeneous differential operator and with gradient dependence are established developing a non-variational approach based on an adequate method of sub-supersolution.

Gradient direction dependencies in natural images

Spatial Vision, 2007
We have used information-theoretic measures to compute the amount of dependency which exists between two and three gradient directions at separate locations in an ensemble of natural images. Control experiments were performed on other image classes: phase randomized natural images, whitened natural images and Gaussian noise images.

Generalized Gradient-Dependent Plasticy Theory

Advanced Materials Research, 2011
Based on the Generalized Plastic Mechanics (GPM) and strain gradient-dependence of yield surfaces, the differential expressions of the volumetric and shear plastic strains are constructed, then the Generalized Gradient-dependent Plastic Mechanics (GGPM) is established to describe the strain localization characteristics and the basic mechanics ...

On the dependence of standard and gradient elastic material constants on a field of defects

Mathematics and mechanics of solids, 2020
In this work, we consider a strain gradient elasticity theory with an extended number of field variables: the displacement vector and an additional scalar field defining the internal micro-deformation.

Dependence of mechanical properties on microstructure of high-textured pyrocarbon prepared via isothermal and thermal gradient chemical vapor infiltration

, 2020
In order to explore the dependence of mechanical properties on the microstructure of high-textured (HT) pyrolytic carbon (PyC), the microstructure and properties of HT PyC specimens prepared by isothermal isobaric chemical vapor infiltration (ICVI) and ...
