On the dependence of standard and gradient elastic material constants on a field of defects
Mathematics and mechanics of solids, 2020In 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.

Generalized Gradient-Dependent Plasticy Theory [PDF]
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 ...

Gradient direction dependencies in natural images
Spatial Vision, 2007We 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.

Dependence of the Depolarization Tensor on the Displacement Gradient [PDF]
Canadian Journal of Physics, 1971 Expressions are given for the first- and second-order derivatives of the depolarization tensor with respect to the displacement gradient. The results are applied to the special case of the sphere.

On the Reynolds number dependence of velocity-gradient structure and dynamics
Journal of Fluid Mechanics, 2018We seek to examine the changes in velocity-gradient structure (local streamline topology) and related dynamics as a function of Reynolds number ( $Re_{\unicode[STIX]{x1D706}}$ ). The analysis factorizes the velocity gradient ( $\unicode[STIX]{x1D608}_{ij}

On gradient dependent diffusivity
Chemical Engineering Science, 1973Abstract It is a known fact that surface diffusion is dependent on temperature and concentration. Data on adsorption of water in microporous silica gel indicate that an additional quantity is influencing diffusivity in such a system. These observations can be explained by a surface diffusivity depending on concentration gradient.

Gradient-dependent heat rectification in thermoelastic solids
Journal of Thermal Stresses, 2021We study heat rectification by means of application of an inhomogeneous distribution of a tensile mechanical stress in: (a) graded thermoelastic systems with constant cross section; (b) non-graded ...

Experimental electron temperature gradient dependence of heavy impurity transport in fusion devices.
Physical Review Letters, 2010The turbulent impurity (nickel) transport dependence on the normalized electron temperature gradient has been analyzed in sawtooth-free electron cyclotron wave heated Tore Supra plasmas. In the core, our experimental analysis shows that the lower R/L((T)(
