ASYMMETRIC LINESHAPE FOR LIGHT SCATTERING BY ELEMENTARY EXCITATIONS

Author(s) : Oliveira, F.
Description : Experimental works on acoustic surface phonons in thin films show the existence of asymmetric cross-sections. These lineshapes are deviation from the Lorentzian shape /l/. We use previous work /2/ in order to show that the origin of those asymmetries lies on the time reversa1 properties of the syste...

About fitted finite-difference operators and fitted meshes for solving singularly perturbed linear problems in one dimension

Author(s) : Oliveira, F. Aragão
Description : Classical finite-difference operators on uniform meshes are not appropriate for solving singularly perturbed differential equations due to the effect of the boundary layers.If we want uniformly convergent difference schemes (with respect to some discrete norm), we need to adequate the numerical oper...

RES using RIB

Author(s) : De Oliveira, F.
Description : The Resonant Elastic Scattering (RES) method has been used at GANIL with Radioactive Ions Beams (RIB) in order to study important unbound states. Three examples of studies are given: the first one is related to the important astrophysical reaction 18F(p,α)15O, the second one to the two-proton radioa...

Tingimento da poliamida 6.6 com corantes ácidos, reactivos e directos após modificação superficial com descarga plasmática de dupla barreira dieléctrica (DBD)

Author(s) : Oliveira, F. R.
Description : O tingimento de fibras de poliamida é muito comum com corantes ácidos; entretanto o uso de outras classes de corantes, como reactivos e directos, podem oferecer grandes oportunidades para o desenvolvimento de novos produtos com melhores propriedades como esgotamento, fixação, níveis de solidez, bril...

POWER SPECTRA OF LOCALIZED RETARDED MODES IN A FERROMAGNETIC SLAB

Author(s) : Lima, N. , Oliveira, F.
Description : In the present work we use some previous results on Green function calculations /1/ in order to obtain the density of energy (power spectra) of the localized modes within a ferromagnetic slab. Those results show the power spectra P as a function of frequency ω, the wavevector [MATH] of the external ...

Searching for the best scale that explains bird community composition in a montado systema near Évora (Portugal)

Author(s) : Quinta-Nova, L.C. , Oliveira, F. , Caldeira, R.
Description : The understanding of the relationship between communities and the landscape mosaic, shaped by the different land uses, is important for an integrated management of the habitats. The landscape indexes might be a useful tool for landscape analysis as well as a landscape describer. The scope of this w...
