Harmonic distortion analysis based on Hopf bifurcation theorem and fast fourier transform
(World Scientific, 2007-12)
A frequency domain method is used to estimate the harmonic contents of a smooth oscillation arising from the Hopf bifurcation mechanism. The harmonic contents up to the eighth-order are well estimated, which agree with the ...
Fourier transform infrared spectroscopy-Partial Least Squares (FTIR-PLS) coupled procedure application for the evaluation of fly attack on olive oil quality
(Elsevier, 2013-01)
A Fourier transform infrared spectroscopy–Partial Least Squares (FTIR–PLS) strategy for the determination of the quality of olive fruits and the respective virgin olive oil (VOO) has been developed. This methodology has ...
Porous polycrystal plasticity modeling of neutron-irradiated austenitic stainless steels
(Elsevier Science, 2020-12)
A micromechanical model for quantifying the simultaneous influence of irradiation hardening and swelling on the mechanical stiffness and strength of neutron-irradiated austenitic stainless steels is proposed. The material ...
High strength biobased films prepared from xylan/chitosan polyelectrolyte complexes in the presence of ethanol
(Elsevier, 2021-12)
The effect of different ethanol concentrations (0; 3; 9; 12 and 16 wt%) on the degree of ionization of xylan and chitosan, the characteristics of polyelectrolyte complex (PEC) suspensions, and the derived films, were ...
Chemometric Optimization of a Demineralization Method for Analysing Sediment Organic Matter by Fourier Transform Infrared Spectroscopy
(Springer, 2021-05)
Fourier transform infrared (FTIR) spectroscopy is a widespread and useful technique for characterizing the chemical composition of soil/sediment organic matter (SOM). However, the mineral components of the samples limit ...
FTIR analysis of the interaction of arbutin with dimyristoyl phosphatidylcholine in anhydrous and hydrated states
(Elsevier Science, 2006-11)
In this paper, the interaction of arbutin with dimyristoylphosphatidylcholine bilayers was studied by FTIR spectrometry. The results show that arbutin interacts in different extents with the phosphate and carbonyl groups ...
Mesoporous Thin Films of TiO2 on Attenuated Total Reflection Crystals. An In Situ Fourier-Transform Infrared Study of the Kinetics and Equilibrium of Adsorption and Photocatalysis of Carboxylic Acids
(American Chemical Society, 2013-06)
Highly organized titanium dioxide (TiO2) mesoporous thin films were deposited directly on silicon attenuated total reflection (ATR) crystals by dip-coating, submitted to two different thermal treatments, and characterized ...
Fourier expansion and integral representation generalized Apostol-type Frobenius–Euler polynomials
(Corporación Universidad de la Costa, 2020)
