On the regular-geometric-figure solution to the N-body problem
(2001-09-01)
The regular-geometric-figure solution to the N-body problem is presented in a very simple way. The Newtonian formalism is used without resorting to a more involved rotating coordinate system. Those configurations occur for ...
Frequency stabilization in nonlinear micromechanical oscillators
(Springer, 2012-01)
Mechanical oscillators are present in almost every electronic device. They mainly consist of a resonating element providing an oscillating output with a specific frequency. Their ability to maintain a determined frequency ...
Synchronization properties of self-sustained mechanical oscillators
(Amer Physical Soc, 2013-03)
We study, both analytically and numerically, the dynamics of mechanical oscillators kept in motion by a feedback force, which is generated electronically from a signal produced by the oscillators themselves. This kind of ...
Bifurcations Leading to Nonlinear Oscillations in a 3D Piecewise Linear Memristor Oscillator
(World Scientific Publ Co Pte Ltd, 2014-01-01)
In this paper, we make a bifurcation analysis of a mathematical model for an electric circuit formed by the four fundamental electronic elements: one memristor, one capacitor, one inductor and one resistor. The considered ...
Numerical study of the spherically symmetric Gross-Pitaevskii equation in two space dimensions
(2000-08-01)
The Gross-Pitaevskii equation for Bose-Einstein condensation (BEC) in two space dimensions under the action of a harmonic oscillator trap potential for bosonic atoms with attractive and repulsive interparticle interactions ...
Power flow optimization for grid connected inverter using evolutionary algorithm and additional control loop
(2011-12-28)
In this work it is proposed to validate an evolutionary tuning algorithm in plants composed by a grid connected inverter. The optimization aims the tuning of the slopes of P-Ω and Q-V curves so that the system is stable, ...
