Two dimensional computer simulation of plasma immersion ion implantation
(2004-12-01)
The biggest advantage of plasma immersion ion implantation (PIII) is the capability of treating objects with irregular geometry without complex manipulation of the target holder. The effectiveness of this approach relies ...
Asymptotic, non-linear solutions for ambipolar diffusion in one dimension
(2010)
We study the effect of the non-linear process of ambipolar diffusion (joint transport of magnetic flux and charged particles relative to neutral particles) on the long-term behavior of a non-uniform magnetic field in a ...
Two-fluid simulations of the magnetic field evolution in neutron star cores in the weak-coupling regime
(Oxford University Press, 2020)
In a previous paper, we reported simulations of the evolution of the magnetic field in neutron star (NS) cores through ambipolar diffusion, taking the neutrons as a motionless uniform background. However, in real NSs, ...
Study of magnetic field enhanced plasma immersion ion implantation in Silicon
(Iop Publishing Ltd, 2014-01-01)
A comparison between experimental measurements and numerical calculations of the ion current distribution in plasma immersion ion implantation (PIII) with external magnetic field is presented. Later, Silicon samples were ...
On the mechanics of thermal buckling of oil storage tanks
(Elsevier, 2019-12)
This paper addresses the thermal buckling behavior of tanks having a fixed roof, as employed to store fuel in the oil industry. The study is performed based on finite element analyses of the shell, including linear analysis, ...
Stability of hall equilibria in neutron star crusts
(Institute of Physics Publishing, 2014)
© 2014. The American Astronomical Society. All rights reserved.. In the solid crusts of neutron stars, the advection of the magnetic field by the current-carrying electrons, an effect known as Hall drift, should play a ...
Adiabaticity and gravity theory independent conservation laws for cosmological perturbations
(Elsevier, 2016)
We carefully study the implications of adiabaticity for the behavior of cosmological perturbations. There are essentially three similar but different definitions of non-adiabaticity: one is appropriate for a thermodynamic ...
Lightning Induced Voltages on Overhead Lines above Non-Uniform and Non-Homogeneous Ground
(2014-11)
Abstract: lightning induced voltages are one of the most common sources of failures on distribution networks operating in high lightning activity regions. Traditionally, the selection of insulation levels and protecting ...
Magnetic field evolution and equilibrium configurations in neutron star cores: the effect of ambipolar diffusion
(Oxford University Press, 2017)
As another step towards understanding the long-term evolution of the magnetic field in neutron stars, we provide the first simulations of ambipolar diffusion in a spherical star. Restricting ourselves to axial symmetry, ...
Flow observations at a vertical drop structure
(2006-10)
Results from an experimental study conducted to investigate the characteristics of the velocity field along the jet trajectory of a drop structure are presented. Constant temperature anemometry is used for detailed ...
