Spectral simulation of vector random fields with stationary gaussian increments in d-dimensional euclidean spaces
(Springer, 2017)
This paper addresses the problem of simulating multivariate random fields with stationary Gaussian increments in a d-dimensional Euclidean space. To this end, one considers a spectral turning-bands algorithm, in which the ...
A two band model for superconductivity: probing interband pair formation
(Sociedade Brasileira de Física, 2003-12-01)
We propose a two band model for superconductivity. It turns out that the simplest nontrivial case considers solely interband scattering, and both bands can be modeled as symmetric (around the Fermi level) and flat, thus ...
A two band model for superconductivity: probing interband pair formation
(Sociedade Brasileira de Física, 2003)
The origin of optical activity in complexes of the type [Co(diimine)(2)carbohydrate](2+)
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-05-06)
Complexes of the type Delta- and Lambda-[Co(diimine)(2)carbohydrate](2+) were synthesized with the diimines: 1,10-phenanthroline and 2,2'-bipyridine and with the carbohydrates: aminosugars, hexoses, pentoses and sucrose, ...
Turning a loudspeaker into an active Helmholtz resonator: Underlying law, principle and design methodology
(2018-10-13)
This paper is concerned with how to turn a moving-coil loudspeaker into an active Helmholtz resonator (AHR): that is, an active noise control loudspeaker used in conjunction with a microphone and a feedback controller to ...
Engineering of the band gap induced by Ce surface enrichment in Ce-doped SnO2 nanocrystals
(Elsevier B.V., 2020-10-15)
Surface modification of oxide semiconductors nanocrystals can promote news effects mainly in nanocrystals up to 10 nm in diameter. In these systems, the ratio surface/core is increased, and the quantum effect can not rule ...
Band Gap Narrowing of Bi-Doped NaTaO3 for Photocatalytic Hydrogen Evolution under Simulated Sunlight: A Pseudocubic Phase Induced by Doping
(Amer Chemical Soc, 2021-01-25)
NaTaO3 is a promising material for the production of hydrogen fuel via photocatalytic water splitting, although the wide band gap prevents its application with solar light. In order to overcome this issue, bismuth doping ...
Floquet interface states in illuminated three-dimensional topological insulators
(American Physical Society, 2015-06)
Recent experiments showed that the surface of a three-dimensional topological insulator develops gaps in the Floquet-Bloch band spectrum when illuminated with a circularly polarized laser. These Floquet-Bloch bands are ...
Exploring the Capability of ALOS PALSAR L-Band Fully Polarimetric Data for Land Cover Classification in Tropical Environments
(Ieee-inst Electrical Electronics Engineers Inc, 2016-12-01)
Among different applications using synthetic aperture radar (SAR) data, land cover classification of rain forest areas has been investigated. Previous results showed that L-band is more appropriate for such applications. ...
Wannier functions of a one-dimensional photonic crystal with inversion symmetry
(Iop Publishing Ltd, 2010-11-14)
The maximally localized magnetic and electric Wannier functions of a one-dimensional photonic crystal with inversion symmetry are investigated. The calculated Wannier functions are real and either symmetric or anti-symmetric ...
