Quantum equivalence between the self-dual and the Maxwell-Chern-Simons models nonlinearly coupled to U(1) scalar fields
(Iop Publishing Ltd, 2006-07-21)
The use of master actions to prove duality at quantum level becomes cumbersome if one of the dual fields interacts nonlinearly with other fields. This is the case of the theory considered here consisting of U(1) scalar ...
Automation and cybernetics: Control of a flexible one-link manipulator
(Mcb Univ Press Ltd, 1996-01-01)
States that control is of the essence in cybernetics. Summarizes the dynamic equations for a flexible one-link manipulator moving in the horizontal plane. Employs the finite element method, based on elementary beam theory, ...
Magnetic-field and confinement effects on the effective Land, g factor in AlxGa1-xAs parabolic quantum wells
(Springer, 2010-04-01)
The magnetic-field and confinement effects on the Land, factor in AlxGa1-xAs parabolic quantum wells under magnetic fields applied parallel or perpendicular to the growth direction are theoretically studied. Calculations ...
Reply to Comment on 'validity of Feynman's prescription of disregarding the Pauli principle in intermediate states'
(American Physical Soc, 2000-07-01)
In a recent paper, we raised a question on the validity of Feynman's prescription of disregarding the Pauli principle in intermediate states of perturbation theory. In the preceding Comment, Cavalcanti correctly pointed ...
double-struck D signn-forced symmetry breaking of double-struck O sign (2)-equivariant problems
(2002-10-18)
We use singularity theory to classify forced symmetry-breaking bifurcation problems f(z, λ, μ) = f1 (z, λ) + μf2(z, λ, μ) = 0, where f1 is double-struck O sign (2)-equivariant and f2 is double-struck D sign n-equivariant ...
SDRE CONTROL APPLIED TO AN ELECTROMECHANICAL PENDULUM EXCITED BY A NON-IDEAL MOTOR
(Amer Soc Mechanical Engineers, 2014-01-01)
The dynamical behavior of an electromechanical pendulum system is analyzed by means of the classical perturbation theory. A frequency response model of the system is obtained, and the number of unstable poles are determined ...
Sdre control applied to an electromechanical pendulum excited by a non-ideal motor
(2013-01-01)
The dynamical behavior of an electromechanical pendulum system is analyzed by means of the classical perturbation theory. A frequency response model of the system is obtained, and the number of unstable poles are determined ...
On light dilaton extensions of the Standard Model
(E D P Sciences, 2016-01-01)
We discuss the presence of a light dilaton in Conformal Field Theories deformed by a single scalar operator, in the holographic realization consisting of confining Renormalization Group flows. Then, we apply this formalism ...
Accidental symmetries and massless quarks in the economical 3-3-1 model
(Amer Physical Soc, 2015-02-17)
In the framework of a 3-3-1 model with a minimal scalar sector, known as the economical 3-3-1 model, we study its capabilities of generating realistic quark masses. After a detailed study of the symmetries of the model, ...
Short distance QCD contribution to the electroweak mass difference of pions
(1997-06-01)
It is known that the short distance QCD contribution to the mass difference of pions is quadratic on the quark masses, and irrelevant with respect to the long distance part. It is also considered in the literature that its ...
