Diffusion model for growth of Fe2B layer in pure iron
(Taylor and Francis Online, 2011)
A simple diffusion model is proposed to estimate the growth kinetics of Fe2B layers created at the surface of pure iron. This model employs the mass balance equation at the Fe2B/substrate interface to evaluate the boron ...

Dark-bright gap solitons in coupled-mode one-dimensional saturable waveguide arrays
(2011)
In the present work, we consider the dynamics of dark solitons as one mode of a defocusing photorefractive lattice coupled with bright solitons as a second mode of the lattice. Our investigation is motivated by an experiment ...

Control of the optical properties of silicon and chromium mixed oxides deposited by reactive magnetron sputtering
(ScienceDirect, 2011-03-31)
The development of mixed-oxide thin films allows obtaining materials with better properties than those of the different binary oxides, which makes them suitable for a great number of applications in different fields, such ...

Stability of non-time-reversible phonobreathers
(2011)
Non-time reversible phonobreathers are non-linear waves that can transport energy in coupled oscillator chains by means of a phase-torsion mechanism. In this paper, the stability properties of these structures have been ...

A Lagrangian Transport Model Applied to two Different Brackish Systems: the Baltic Sea and the Guadalquivir River
(IEEE Computer Society, 2011)
the nuclear contamination and other passive particles in the ocean. As a consequence of the Chernobyl accident (April, 26th, 1986), the radioactive plume drift over many countries in Europe, and after some days, the ...

Discrete breathers in a nonlinear electric line: modeling, computation, and experiment
(2011)
We study experimentally and numerically the existence and stability properties of discrete breathers in a periodic nonlinear electric line. The electric line is composed of single cell nodes, containing a varactor diode ...

Existence of dark solitons in a class of stationary nonlinear Schrödinger equations with periodically modulated nonlinearity and periodic asymptotics
(2011)
In this paper, we give a proof of the existence of stationary dark solitonsolutions or heteroclinic orbits of nonlinear equations of Schrödinger type with periodic inhomogeneous nonlinearity. The result is illustrated with ...

Improving the visible transmittance of low-e titanium nitride based coatings for solar thermal applications
(ScienceDirect, 2011-12-15)
Low-emissivity (low-e) coatings on glass are nowadays extensively used for energy saving applications in architectural windows and on solar thermal collectors. In this work the feasibility of TiN-based layers as low-e ...

Interaction of moving discrete breathers with interstitial defects
(American Institute of Mathematical Sciences, 2011)
In this paper, interstitial migration generated by scattering with a mobile breather is investigated numerically in a Frenkel-Kontorova onedimensional lattice. Consistent with experimental results it is shown that interstitial ...
