On fermion masses and mixing in a model with symmetry
In a recently proposed multi-Higgs extension of the standard model in which
discrete symmetries, and are imposed we show that, after
accommodating the fermion masses and the mixing matrices in the charged
currents, the mixing matrices in the neutral currents induced by neutral
scalars are numerically obtained. However, the flavor changing neutral currents
are under control mainly by mixing and/or mass suppressions in the neutral
scalar sector.Comment: Version accepted for publication in International Journal of Modern
Physics A. In this version we added a discussion on the charged lepton and
neutrino masses. The title has been changed. Other minor changes do not
modify the conclusion
Fractional dynamics in the describing function analysis of nonlinear friction
This paper studies the describing function (DF) of systems constituted by a mass subjected to nonlinear friction. The friction force is decomposed in three components namely, the viscous, the Coulomb and the static forces. The system dynamics is analyzed in the DF perspective revealing a fractional-order behaviour. The reliability of the DF method is evaluated through the signal harmonic content and the limit cycle prediction.N/
Describing function of systems with nonlinear friction
This paper studies the describing function (DF) of systems composed of a mass subjected to nonlinear friction. The friction force is decomposed in three components namely, the viscous, the Coulomb and the static forces. The system dynamics is analyzed in the DF perspective and the reliability of the DF method is evaluated through the signal harmonic content.N/
Describing function of a simple mechanical system with non-linear friction
This paper studies the describing function (DF) of systems constituted by a mass subjected to nonlinear friction. The friction force is decomposed in two components namely, the viscous and the Coulomb friction. The system dynamics is analyzed in the DF perspective revealing a fractional-order behaviour. The reliability of the DF method is evaluated through the signal harmonic contents.N/

Impacts of the integration of Chinese managers in the Western economies the case of Brazil
The Chinese rise to economic and political power at the global level has been at the centre of scholarly and political debates. The purpose of this article will be to analyse the integration of Chinese managers in the Western economy. The methodology will be a bibliography, descriptive, and explanatory, making a comparison between the Brazilian trade and China. The type of literature review is the integrative one, intending to conduct a meta-analysis of the literature and answer specific research questions. The conclusions explore some normative implications of the results of the economy in China and Brazil. On the one hand, China has become a dominant and undeniable shareholder in multiple industries, including the energy sector and R&D with high governmental investments. However, the West appears not to be appropriating its business practices, so the learning process is not fully operationalised.info:eu-repo/semantics/acceptedVersio
