A New Treatment for Some Periodic Schrodinger Operators I: The Eigenvalue
(Iop Publishing Ltd, 2018-02-01)
We study the problem of how the Floquet property manifests for periodic Schrodinger operators, which are known to have multiple of asymptotic spectral solutions. The main conclusions are made for elliptic potentials, we ...

Homogenization Techniques for Improving the Calculations of Scattering by 1-D Fast Oscillating Periodic Surfaces
(2019)
This paper deals with the efficient computation of scattering problems by fast oscillating periodic surfaces using two-scale expansion homogenization techniques. The proposed method splits the field between an effective ...
Effect of radial velocity profiles on axial dispersion in packed beds: asymptotic behaviour
(Brazilian Society of Chemical Engineering, 2021-09)
Axial dispersion of a solute in a flow through packed beds arises from molecular diffusion, velocity variations at the interstitial-pore scale and systematic radial velocity profiles. Currently, there is not a widely ...
Efficient semiparametric estimation of quantile treatment effects
(Fundação Getulio Vargas. Escola de Pós-graduação em Economia, 2003-01)
This paper presents calculations of semiparametric efficiency bounds for quantile treatment effects parameters when se1ection to treatment is based on observable characteristics. The paper also presents three estimation ...
Inequality treatment effects
(Escola de Pós-Graduação em Economia da FGV, 2005-05-05)
This paper presents semiparametric estimators for treatment effects parameters when selection to treatment is based on observable characteristics. The parameters of interest in this paper are those that capture summarized ...
Identification and estimation of interventions using changes in inequality measures
(2010-06-16)
This paper presents semiparametric estimators of changes in inequality measures of a dependent variable distribution taking into account the possible changes on the distributions of covariates. When we do not impose ...
