Effect of asymmetry in the restoring force of the click mechanism in insect flight
Abolfathi, Ali; Changizi, M. Amin; Brennan, Michael J. [UNESP]; IOPMade available in DSpace on 2021-06-25T12:18:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; The aim of this paper is to examine the effect of asymmetry in the force-deflection characteristics of an insect flight mechanism on its nonlinear dynamics. An improved simplified model for insect flight mechanism is suggested and numerical methods are used to study its dynamics. The range at which the ...

No. of bitstreams: 0 Previous issue date: 2019-01-01; Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Application of titanium alloys for orthodontic implants have increase in last years and it has generated a great amount of titanium chips which are disposed as metal scrap. Titanium carbide has high hardness and can be applied as coat...
Mesoscopic superconductivty in application
Barba-Ortega, J.; Bautista-Ruiz, J.; Sardella, E. [UNESP]; IOPMade available in DSpace on 2020-12-10T19:40:41Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; The Ginzburg-Landau theory, applied to superconducting materials is based on thermo-magneto-electro-dynamic concepts as phase transitions that enrich the class on this subject. Thus, in this contribution we expose the Ginzburg-Landau time-dependent equations, show the mathematical form for two nano-scal...

Lepton masses and mixing and lepton number violating processes in the minimal 3...
Machado, A. C. B. [UNESP]; Montano, J. [UNESP]; Pleitez, V. [UNESP]; IOPMade available in DSpace on 2018-11-26T17:45:05Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-01-01; We consider the minimal 3-3-1 model with sterile neutrinos transforming as singlet under the SU(3)(L) circle times U(1)(X) symmetry and we find numerical solutions for these matrices by imposing that besides the observed lepton masses, they also give the observed mixing matrix in the lepton sector, the ...
Leptonic decay constants of the pion and its excitations in holographic QCD
Krein, Gastao [UNESP]; IOPMade available in DSpace on 2018-11-26T17:10:31Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; We present results of a recent study of the structure of excited pions within a chiral holographic model for QCD. In particular, we prove that the leptonic decay constants of the excited states of the pion vanish in the chiral limit when chiral symmetry is dynamically broken. Comparisons are made with c...

No. of bitstreams: 0 Previous issue date: 2016-01-01; In this work we calculate the cross section of the scattering process of the Duffin-Kemmer-Petiau theory coupling with the Maxwell's electromagnetic field. Specifically, we find the propagator of the free theory, the scattering amplitudes and cross sections at Born level for the Moeller and Compton scat...
Impact of a magnetic field on the thermodynamics of magnetized quark matter
Farias, R. L. S.; Timoteo, V. S.; Avancini, S.; Pinto, M. B.; Krein, G. [UNESP]; IOPMade available in DSpace on 2018-11-26T17:10:32Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-01-01; We investigate the effect of a magnetic field on the thermodynamics of magnetized quark matter at finite temperature. By using the Nambu Jona-Lasino (NJL) model, we show that the lattice results for the quark consensate can be reproduced when the coupling constant G of the model decreases with the magne...
