Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)
In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ...
Dynamic Stark effect and the Coulomb-Volkov approximation
(Institute of Physics Publishing, 2009-10)
A modified Coulomb-Volkov theory is used to study the interaction of intense laser pulses with atomic Hydrogen. Photon energy greater than the ionization potential and non-perturbative conditions are considered. The dynamical ...
On the consequences of the constraint of incompressibility with regard to a new class of constitutive relations for elastic bodies: small displacement gradient approximation
(Springer, 2016)
Recently, there has been an interest in the development of implicit constitutive relations between the stress and the deformation gradient, to describe the response of elastic bodies as such constitutive relations are ...
The Taurus Boundary of stellar/substellar (TBOSS) survey. II. Disk masses from ALMA continuum observations
(IOP Publishing Ltd, 2018)
We report 885 mu m ALMA continuum flux densities for 24 Taurus members spanning the stellar/substellar boundary with spectral types from M4 to M7.75. Of the 24 systems, 22 are detected at levels ranging from 1.0 to 55.7 ...
Mecánica de fractura determinista: resolución de problemas mediante simulación numérica
(2015-05-05)
This thesis deals with different numerical methods based on finite element techniques, applicable to deterministic fracture mechanics. Within this subject, two aspects are studied: a) Evaluation of parameters wich predicts ...
Double ionization of helium by fast electrons with the Generalized Sturmian Functions method
(Iop Publishing, 2015-02)
The double ionization of helium by high energy electron impact is studied. The corresponding four-body Schrödinger equation is transformed into a set of driven equations containing successive orders in the projectile–target ...
Study of absorption spectrum and dynamics evaluation of the indocyanine-green first singlet excited state
(WILEY-BLACKWELL, 2011)
Excited state absorption and excited state dynamics of indocyanine-green (ICG) dissolved in dymethyl sulfoxide were measured using white-light continuum Z-scan (WLCZScan) and white-light continuum pump-probe (WLCPP) ...
