Analysis and measurement of the non-linear refractive index of SiOxNy using pedestal waveguides
(Ieee, 2019-01-01)
In this work, the non-linear refractive index (n(2)) of silicon oxynitride (SiOxNy) is determined, obtaining a value for this material of n(2) = 2.11x10(-19) m(2)/W. The results demonstrate that this material has interesting ...

(2006-04-01)
The mainstreams of research papers developed to analysis of electrical systems power quality for non-linear loads are conducted for low voltage feed. This, if in one hand have furnished important results about the performance ...
A contribution for nonlinear structural dynamics characterization of cantilever beams
(2005-12-01)
Successful experiments in nonlinear vibrations have been carried out with cantilever beams under harmonic base excitation. A flexible slender cantilever has been chosen as a convenient structure to exhibit modal interactions, ...
Fast nonlinear region localisation for nonlinear dielectric spectroscopy of biological suspensions
(Elsevier Science, 2013-06)
The nonlinear properties of biological suspensions have been previously presented as a bulk phenomenon without the influences of the electrodes. However, some authors have showed that the behaviour of a biological suspension ...
Advances in the non-linear optical investigation of lyotropic-like low-density human lipoproteins in the native and oxidised states
(Taylor & Francis Ltd, 2014-03-04)
The Z-Scan optical technique was recently used to measure the non-linear optical response of human lipoproteins, in particular low-density lipoprotein (LDL) particles, regarding their oxidative (atherogenic) state. the ...
Identificação de um sistema experimental caótico: circuito de Chua
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia ElétricaUTFPR, 2019-06-28)
This work presents concepts of nonlinear system identification and chaos through NARMAX representations and the Chua’s circuit forced with a DC voltage source in series with the Chua’s diode. In this context, were used ...
