Fringe pattern normalization consists in the background suppression and modulation normalization of a given fringe pattern, this process gives as a result a pure sinusoidal phase modulated signal. Normalization is an important operation in the d[...]![]()

Alonso, J.L. ; Boucaud, Ph. ; Martín Mayor, Víctor ; van der Sijs, A.J. | Elsevier Science BV | 1998-04We present a 2+1-dimensional lattice model for the copper oxide superconductors and their parent compounds, in which both the charge and spin degrees of freedom are treated dynamically. The spin-charge coupling parameter is associated to the dop[...]![]()

Dobado González, Antonio ; Herrero, M. J. ; Pelaez, J.H. ; Morales, E.R. ; Urdiales, M.T. | Elsevier Science BV | 1995-06-15In the present work we study the predictions for WZ and ZZ production at the LHC with the Electroweak Chiral Lagrangian (EChL) approach. Our analysis will be focused on the less favored case from the experimental point of view, in which the pred[...]![]()

The Flexible Image Transport System (FITS) standard has been a great boon to astronomy, allowing observatories, scientists and the public to exchange astronomical information easily. The FITS standard, however, is showing its age. Developed in t[...]![]()

Llanes Estrada, Felipe José ; General, Ignacio J. ; Wang, Ping ; Cotanch, Stephen R. | Elsevier Science BV | 2007-09-30Highlights in the search for nonconventional (non-q.q) meson states are the ?1(1400) and ?1(1600) exotic candidates. Should they exist, mounting theoretical arguments suggest that they are tetraquark molecular resonances excitable by meson resca[...]![]()

The aim of this paper is to analyse linear production with committee control situations arising when controllers face the possibility of graduating their options. In order to model these situations, we consider several kinds of fuzzy controls, w[...]![]()

This paper presents an approach to the local stereovision matching problem using edge segments as features with four attributes. Based on these attributes we compute a matching probability between pairs of features of the stereo images. A corres[...]![]()

Chubykalo-Fesenko, Oksana ; Kauffman, J. ; Lengsfield, B. ; Smirnov Rueda, Román | Elsevier Science BV | 2002-04The standard Metropolis Monte Carlo is used to simulate thermal magnetization decay in ensemble of interacting and non-interacting particles. The fitting of demagnetization curves to simple Neel Arrhenius model, using the volume distribution, su[...]![]()

Malyshev, Andrey ; Malyshev, V.A. ; Domínguez-Adame Acosta, Francisco | Elsevier Science BV | 2003-04-07We present a theoretical analysis of low-temperature quenching of one-dimensional Frenkel excitons that are localized by moderate on-site (diagonal) uncorrelated disorder. Exciton diffusion is considered as an incoherent hopping over localizatio[...]![]()

The magnetism in the inherently nanolaminated ternary MAX-phase Cr_(2)GeC is investigated by element-selective, polarization and temperature-dependent, soft X-ray absorption spectroscopy and X-ray magnetic circular dichroism. The measurements in[...]![]()

In the work presented the magnetic properties of the high pressure ilmenite phase Mn_2FeSbO_6 are investigated in detail. It is shown that Mn_2FeSbO_6 ilmenite is ferrimagnetic (T_N approximate to 270 K) and exhibits a near-zero coercive field H[...]![]()

Utilizing an effective QCD Coulomb gauge Hamiltonian with linear confinement specified by lattice, we report a relativistic many-body calculation for the light exotic and charmed hybrid mesons. The Hamiltonian successfully describes both quark a[...]![]()

Alonso, J. L. ; Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor | Elsevier Science BV | 2000-05-11We study the linear response to an external electric field of a system of fermions in a lattice at zero temperature. This allows to measure numerically the Euclidean conductivity which turns out to be compatible with an analytical calculation fo[...]![]()
