1. Pattern Identification on the Nonlinear Radial Motion of an Oscillating Spherical Bubble Using Neural Networks
Abstract The main goal of this article is to study the oscillatory motion of a spherical gas bubble immersed in a Newtonian liquid subjected to a harmonic pressure excitation. We use the classical Rayleigh-Plesset equation to study the radial motion of the bubble undergoing a forcing acoustic pressure field. The second order nonlinear ordinary differential e

2. Estudo da dinâmica de um laser de fibra de dois anéis dopado a érbio / Study of dynamics of an erbium-doped fiber dual-ring laser
O laser de fibra de dois anéis dopado a érbio é um sistema dinâmico quadridimensional a tempo contínuo, modelado por um conjunto de quatro equações diferenciais ordinárias de primeira ordem autônomas, e tem sido investigado nos últimos anos devido as diversas aplicações, como por exemplo, controle de caos, sincronização de caos e sistemas de te

3. Low frequency oscillations and bifurcation diagram in semi-insulating GaAs samples
We present an experimental study of bifurcation diagrams from low frequency current oscillations (LFO) measurements obtained from semi-insulating GaAs samples grown by low temperature molecular beam Epitaxy (LT-MBE). The considered growth temperatures were 215ºC and 265ºC. LFO are considered to be spontaneously generated oscillations under constant applied

4. InvestigaÃÃo do comportamento dinÃmico de biorreatores contÃnuos do tipo tanque perfeitamente agitados atravÃs de diagramas de bifurcaÃÃo
In this work, a theoretical study on the dynamic behavior of fermentation was done using a model constructed to represent the continuous culture of Zymomonas mobilis in a stirred tank bioreactor. The model was analyzed by dynamic simulation and by drawing bifurcation diagram, to study the influence of the parameters of the model in the stability and in the a

5. Estudo computacional-experimental do comportamento oscilatÃrio em fermentaÃÃes contÃnuas com Zymomonas mobilis
Diversos relatos de comportamento oscilatÃrio em fermentaÃÃes contÃnuas em CSTBRâs jà foram feitos e os microorganismos que tÃm apresentado esse comportamento dinÃmico mais freqÃentemente sÃo Saccharomyces cerevisiae e Zymomonas mobilis. A ocorrÃncia de oscilaÃÃes pode favorecer ou prejudicar os processos bioquÃmicos. Desta forma, à fÃcil per

6. Analise não linear de sistemas dinamicos holonomos não ideais / Nonlinear anaIysis of non ideals holonomic dynamical systems
Several times the mechanical systems join the behavior described by laws of motion to the dynamic of their operation. Their solution pass by adopted simplified hypotheses in order to obtain a representative and helpful mathematical model. When the energy source used in the bringing to the action of the motion has limited power, i.e., there is not sufficient

7. Active hair-bundle motility harnesses noise to operate near an optimum of mechanosensitivity
The ear relies on nonlinear amplification to enhance its sensitivity and frequency selectivity to oscillatory mechanical stimuli. It has been suggested that this active process results from the operation of dynamical systems that operate in the vicinity of an oscillatory instability, a Hopf bifurcation. In the bullfrog's sacculus, a hair cell can display spo
