Discriminating chaotic and stochastic dynamics through the permutation spectrum test
(American Institute Of Physics, 2014-09)
In this paper, we propose a new heuristic symbolic tool for unveiling chaotic and stochastic dynamics: the permutation spectrum test. Several numerical examples allow us to confirm the usefulness of the introduced methodology. ...
Dynamic reduced model and stochastic aspects for PFGM curved beams with variable curvature
(Pergamon-Elsevier Science Ltd, 2021-01)
In this paper a new 1D finite element model for dynamic calculations of PGFM curved beams with variable curvature is developed. The reduced high-speed calculation model allows stochastic aspects in the dynamic of the ...
Locally Linearized methods for the simulation of stochastic oscillators driven by random forces
(Springer, 2017-03)
In this work, the performance of Locally Linearized integrators for the numerical simulation of stochastic oscillators driven by random forces is studied. This includes the reproduction of a number of dynamical properties ...
Joint dynamic probabilistic constraints with projected linear decision rules
(EMAp - Escola de Matemática Aplicada, 2016)
We consider multistage stochastic linear optimization problems combining joint dynamic probabilistic constraints with hard constraints. We develop a method for projecting decision rules onto hard constraints of wait-and-see ...
Linear Processes in Stochastic Population Dynamics: Theory and Application to Insect Development
(Hindawi Publishing Corporation, 2014-02)
We consider stochastic population processes (Markov jump processes) that develop as a consequence of the occurrence of random events at random time intervals. The population is divided into subpopulations or compartments. ...
Simultaneous optimization of topology and supplemental damping distribution for buildings subjected to stochastic excitation
(2021)
Supplemental damping devices present an attractive means to improve the structural system. Typically, dampers are designed after the structural system is selected, and they are added to increase structural damping and ...

NOISE and ULTRAVIOLET DIVERGENCES IN SIMULATIONS of GINZBURG-LANDAU-LANGEVIN TYPE of EQUATIONS
(World Scientific Publ Co Pte Ltd, 2012-08-01)
The time evolution of an order parameter towards equilibrium can be described by nonlinear Ginzburg-Landau (GL) type of equations, also known as time-dependent nonlinear Schrodinger equations. Environmental effects of ...
