A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model: 2D results [PDF]
, 2011 The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models which involve gradients of the strain eld means that the $C^0$ continuity

Potential-Function Proofs for Gradient Methods. [PDF]
Theory Comput., 2019 This note discusses proofs of convergence for gradient methods (also called “first-order methods”) based on simple potential-function arguments. We cover methods like gradient descent (for both smooth and non-smooth settings), mirror descent, and some accelerated variants.

Water Potential Gradients in Field Tobacco [PDF]
Plant Physiology, 1970 A pressure chamber was used to establish the vertical gradients of leaf water potential (Psi(Leaf)) and stem water potential (Psi(Stem)) in field-grown tobacco (Nicotiana tabacum L. var. Havanna seed 211) at three different times of day. Leaves enclosed in polyethylene bags and aluminum foil the previous afternoon and left to equilibrate overnight were

Study on potential gradient in Ti anodization
Electrochemistry Communications, 2023 Porous oxides or nanotubes are obtained through the anodization of valve metal. However, the mechanism of nanotube growth remains unclear. Traditional field-assisted dissolution (FAD) theory has many limitations, such as its inability to explain the ...

Bio-potential amplifier for potential gradient measurements [PDF]
Journal of Physics: Conference Series, 2007 This work proposes a bio-potential amplifier suitable for measurements from an electric potential gradient sensor, in electro-encephalography (EEG). The sensor is an array made by three electrodes placed on the vertices of an equilateral triangle of reduced size.

Evaluation Model for the Scope of DC Interference Generated by Stray Currents in Light Rail Systems
Energies, 2019 Electrochemical corrosion caused by stray currents reduces the lifespan of buried gas pipelines and the safety of light rail systems. Determining the scope of stray current corrosion will help prevent the corrosion of existing buried pipelines and ...

The dynamics of the gradient of potential vorticity [PDF]
Journal of Physics A: Mathematical and Theoretical, 2010 The transport of the potential vorticity gradient $\bnabla{q}$ along surfaces of constant temperature $θ$ is investigated for the stratified Euler, Navier-Stokes and hydrostatic primitive equations of the oceans and atmosphere using the divergenceless flux vector $\bdB = \bnabla Q(q)\times\bnablaθ$, for any smooth function $Q(q)$.
