In this paper, we demonstrate that it is possible to combine two computational approaches, usually used in very different contexts, namely, the Green-Kubo formalism and statistical solve Boltzmann transport equation calculate thermal conductivity of semiconductors. framework, first phonon solved by Monte Carlo method according Debye-Callaway or Holland formalisms, then flux autocorrelation calc...

the solubility of co2 in the primary, secondary, tertiary and sterically hindered amine aqueous solutions at various conditions was studied. in the present work, the modified kent-eisenberg (m-ke), the extended debye-hückel (e-dh) and the pitzer models were employed to study the solubility of co2 in amine aqueous solutions. two explicit equations are presented to evaluate the concentration of h...

In this work, the eSAFT-VR Mie equation of state (EoS) is extended to low relative permittivity, non-aqueous solutions. The effect using different permittivity relations for electrolyte solutions studied, ranging from experimentally measured values a salt-composition independent permittivity. Furthermore, approaches characteristic diameters in Debye-Hückel and Born terms presented. EoS reparame...

We deal with the propagation of broadband Schell-model sources in nonlinear media with finite relaxation time. The approach is based on a study of the Wigner distribution function and on a separation of scales technique between the microscopic random fluctuations of the field and the macroscopic intensity profile. The regime in which the nonlinearity is strong and slow is considered. Precise re...

In this paper, we study the existence and uniqueness in I R N of Poisson's equation coupled with Boltzmann's relation which gives a particular expression of the electron's density. We consider also the case where the ionic density vanishes. At last, an asymptotic analysis yields a proof of the quasineutrality hypothesis of this model where the Debye length can be neglected in comparison with th...

We study the response functions (chromo-electric susceptibilities) for an interacting quark-gluon plasma. The interaction effects have been encoded in the effective fugacities for quasi-partons which are extracted self-consistently from the two equations of state for hot QCD. The first one is the fully perturbative O(g) EOS and, the second one which is O(g ln(1/g)), incorporates some non-pertur...

In this paper, we will present a unified formulation of discontinuous Galerkin method (DGM) for Maxwell’s equations in linear dispersive and lossy materials of Debye type and in the artificial perfectly matched layer (PML) regions. An auxiliary differential equation (ADE) method is used to handle the frequency-dependent constitutive relations with the help of auxiliary polarization currents in ...

In order to access the severity of degradation in a water tree affected cable, it is necessary to obtain a physical representation of the insulation. This is especially the case when trying to determine the risk of failure of the cable, or the remaining life, which is dependant on the length of the longest water tree in the insulation. Generally, there has not been a large effort found in publi...
