Existence of positive T-periodic solutions of a generalized Nicholson’s blowflies model with a nonlinear harvesting term
(Elsevier, 2012-09)
We give sufficient and necessary conditions for the existence of at least one positive T -periodic solution for a generalized Nicholson’s blowflies model with a nonlinear harvesting term. Our results extend those of the ...
Periodic solutions for indefinite singular equations with singularities in the spatial variable and non-monotone nonlinearity
(American Institute of Mathematical Sciences, 2018-10)
TWe prove the existence of T−periodic solutions for the second order non-linear equation u0 1 − u02 0 = h(t)g(u), where the non-linear term g has two singularities and the weight function h changes sign. We find a relation ...
The research and study paths in the secondary school: the case of the polynomial functions of the second degree
(Scientia Educologica, 2013-03)
This analysis introduces the pedagogy of research and questioning the world within the Math classrooms at secondary schools in Argentina by using Research and Study Paths (RSP). The RSP have been proposed by Chevallard in ...
Uma introdução à invariância conforme na Teoria das Cordas
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2018-10-11)
In this work we study the formalism of Conformal Field Theory (CFT) and apply it to the theory of strings and superstrings. We also use the BRST quantization technique to obtain the string spectrum together with the ...

Application of H-infinity Theory to a 6 DOF Flight Simulator Motion Base
(ABCM BRAZILIAN SOC MECHANICAL SCIENCES & ENGINEERINGRIO DE JANEIRO RJ, 2012)
The purpose of this study is to apply inverse dynamics control for a six degree of freedom flight simulator motion system. Imperfect compensation of the inverse dynamic control is intentionally introduced in order to ...
