Boundary fluxes for nonlocal diffusion
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2007)
We study a nonlocal diffusion operator in a bounded smooth domain prescribing the flux through the boundary. This problem may be seen as a generalization of the usual Neumann problem for the heat equation. First, we prove ...
Normality and difference in education: relational encounters at school boundaries
(2021)
Substantialist ethnographic approaches have been questioned for situating studies into stable groups and places, thereby creating rigid categories of diversity. In this study, we approached school normality through a ...
A nonlocal nonlinear diffusion equation with blowing up boundary conditions
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2008)
We deal with boundary value problems (prescribing Dirichlet or Neumann boundary conditions) for a nonlocal nonlinear diffusion operator which is analogous to the porous medium equation. First, we prove existence, uniqueness ...
Fractal approach to ac impedance spectroscopy studies of ceramic materials
(2001-11-01)
A novel fractal model for grain boundary regions of ceramic materials was developed. The model considers laterally inhomogeneous distribution of charge carriers in the vicinity of grain boundaries as the main cause of the ...
On the supersymmetry invariance of flat supergravity with boundary.
The supersymmetry invariance of flat supergravity (i.e., supergravity in the absence of any internal scale in the Lagrangian) in four dimensions on a manifold with non-trivial boundary is explored. Using a geometric approach ...
Designing an enterprise social tool for cross-boundary communication, coordination, and information sharing
(Assoc Computing Machinery, 2012)
This paper discusses the design of a social tool for cross-boundary communication, coordination, and information sharing in a large organization. Based on insights and requirements gathered in qualitative and quantitative ...
New features of the morphotropic phase boundary in the PbZrO 3-PbTiO3 system: A Raman spectroscopy study
(Taylor & Francis Ltd, 2002-01-01)
In this work we present a Raman study of PbZr1-xTi xO3 ceramics with composition values close to the morphotropic phase boundary region. The analysis of the Raman spectra leads to the determination of the monoclinic phase ...
Calculation of the natural frequencies and mode shapes of a Euler–Bernoulli beam which has any combination of linear boundary conditions
(2019-09-01)
There are well-known expressions for natural frequencies and mode shapes of a Euler-Bernoulli beam which has classical boundary conditions, such as free, fixed, and pinned. There are also expressions for particular boundary ...
Fundamental solutions and dual boundary element methods for fracture in plane Cosserat elasticity
(Royal Soc, 2015)
In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of ...
