Using generic order moments for separation of dependent sources with linear conditional expectations
(European Association For Signal Processing, 2013)
In this work, we approach the blind separation of dependent sources based only on a set of their linear mixtures. We prove that, when the sources have a pairwise dependence characterized by the linear conditional expectation ...

Anisotropic third-moment estimates of the energy cascade in solar wind turbulence using multispacecraft data
(American Physical Society, 2011-10)
The first direct determination of the inertial range energy cascade rate, using an anisotropic form of Yaglom's law for magnetohydrodynamic turbulence, is obtained in the solar wind with multispacecraft measurements. The ...
On coupled transversal and axial motions of two beams with a joint
(Academic Press Inc Elsevier Science, 2008-03)
In this paper we develop and analyze a mathematical model for combined axial and transverse motions of two Euler-Bernoulli beams coupled through a joint composed of two rigid bodies. The motivation for this problem comes ...
Weed Emergence Models
(Springer Nature Switzerland AG, 2020)
Weed emergence models are practical tools that aim to describe the dynamics of emergence in the field. Such models can be conceptualized from two main perspectives: a reductionist/mechanistic approach and an empirical ...
Probabilistic 3-D time-lapse inversion of magnetotelluric data: Application to an enhanced geothermal system
(Wiley Blackwell Publishing, Inc, 2015-12)
Surface-based monitoring of mass transfer caused by injections and extractions in deep boreholes is crucial to maximize oil, gas and geothermal production. Inductive electromagnetic methods, such as magnetotellurics, are ...
Theoretical study about alkali metal adsorption on pristine and defective (8,0) SWCNT: Geometrical, magnetic and electronic changes
(Elsevier Science, 2020-05-30)
In this work we performed density functional theory (DFT) calculations, analyzing the effects of adsorption of several alkali metals (AM) on pristine and defective (8,0) single-wall carbon nanotube (SWCNT). We found that ...
Structural and magnetic properties of Ni/Pt multilayers
(Elsevier Science, 2007-10)
In this work, the variation of the magnetic moments of the Ni/Pt multilayers are studied using the linearized augmented plane waves (LAPW) method in the framework of the density functional theory (DFT) implemented in the ...
