Modeling of Chloride Distribution in Cement‐Based Materials with Neumann Boundary Condition [PDF]
Advances in Materials Science and Engineering, 2018 The nonstable transport of chloride in cement-based materials, including diffusion, convection, and chloride binding, is described as a general form of Fick’s law.

The principal eigenvalue of the ∞-Laplacian with the Neumann boundary condition [PDF]
ESAIM: Control, Optimisation and Calculus of Variations, 2010 We prove the existence of a principal eigenvalue associated to the $\infty$-Laplacian plus lower order terms and the Neumann boundary condition in a bounded smooth domain. As an application we get uniqueness and existence results for the Neumann problem and a decay estimate for viscosity solutions of the Neumann evolution problem.

Identification hyperbolic problems with the Neumann boundary condition
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 In the present study, an identification problem with the Neumann boundary condition for a one-dimensional hyperbolic equation is investigated. Stability estimates for the solution of the identification problem are established. Furthermore, a first order

Approximation of tricomi problem with Neumann boundary condition
Numerische Mathematik, 1984 The Tricomi problem with Neumann boundary condition is reduced to a degenerate problem in the elliptic region with a non-local boundary condition and to a Cauchy problem in the hyperbolic region. A variational formulation is given to the elliptic problem and a finite element approximation is studied.

Nonlocal problems with Neumann boundary conditions [PDF]
Revista Matemática Iberoamericana, 2017 We introduce a new Neumann problem for the fractional Laplacian arising from a simple probabilistic consideration, and we discuss the basic properties of this model. We can consider both elliptic and parabolic equations in any domain. In addition, we formulate problems with nonhomogeneous Neumann conditions, and also with mixed Dirichlet and Neumann ...

Supercooled Stefan problem with a Neumann type boundary condition [PDF]
Electronic Journal of Differential Equations, 2020 We consider a supercooled one-dimensional Stefan problem with a Neumann boundary condition and a variable thermal diffusivity. We establish a necessary and sufficient condition for the heat flux at the fixed face x=0, in order to obtain existence ...

On a Waveguide with Frequently Alternating Boundary Conditions: Homogenized Neumann Condition [PDF]
Annales Henri Poincaré, 2010 We consider a waveguide modeled by the Laplacian in a straight planar strip. The Dirichlet boundary condition is taken on the upper boundary, while on the lower boundary we impose periodically alternating Dirichlet and Neumann condition assuming the period of alternation to be small. We study the case when the homogenization gives the Neumann condition

Variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition
Le Matematiche, 2010 The aim of this paper is the study of variational-hemivariational inequalities with nonhomogeneous Neumann boundary condition. Sufficient conditions for the existence of a whole sequence of solutions which is either unbounded or converges to zero are ...

The Neumann numerical boundary condition for transport equations
, 2019 International audienceIn this article, we show that prescribing homogeneous Neumann type numerical boundary conditions at an outflow boundary yields a convergent discretization in $\ell^\infty$ for transport equations.
