Numerical experiments on the determination of stress concentration factors in orthotropic perforated plates subjected to in plane loading
(Techno-Press, 2009-07)
As it is known, laminated composite materials are increasingly used in many technological applications, and in some instance, cutouts must be made into laminated panels for practical reasons, changing the stress distribution. ...
Natural frequencies of thin, rectangular plates with holes or orthotropic "patches" carrying an elastically mounted mass
(Pergamon-Elsevier Science Ltd, 2006-07)
The approximate solution for the title problem is obtained in the case of simply supported and clamped rectangular plates made of isotropic or orthotropic materials. A variational approach (the well known Rayleigh-Ritz ...
Thomas–Fermi–Dirac calculations of valence band states in two p-type delta-doped ZnSe quantum wells
(Wiley, 2005-02)
We present the hole sub-band structure study in two p-type δ-doped ZnSe QW’s. An analytical expression
for the Hartree–Fock potential is obtained following the lines of the Thomas–Fermi–Dirac (TFD) approximation.
We have ...
Theoretical and experimental study of the excitonic binding energy in GaAs/AlGaAs single and coupled double quantum wells
(2013-07-31)
This paper discusses the theoretical and experimental results obtained for the excitonic binding energy (Eb) in a set of single and coupled double quantum wells (SQWs and CDQWs) of GaAs/AlGaAs with different Al concentrations ...

Modelagem de vigas em concreto armado avaliando a presença de furos e aberturas através do método dos elementos finitos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2015-06-18)
Most of projects which is part of construction are often created by different professionals. This outsourcing of projects can bring the lack of compatibility among them. For example, the passage of pipe through structural ...
Destilação instantânea em regime transiente: Dorna Volante modificada
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-03-29)
In the intense search for better environmental conditions, it is necessary not only to invest in renewable fuels but also to seek improvements in the production processes of these fuels. With this in mind, in this work the ...
Modeling of organic light-emitting diodes with graded concentration in the emissive multilayer
(American Institute of Physics (AIP), 2004-02-15)
We model the electrical behavior of organic light-emitting diodes whose emissive multilayer is formed by blends of an electron transporting material, tris-(8-hydroxyquinoline) aluminum (Alq(3)) and a hole transporting ...
