Fermi acceleration and its suppression in a time-dependent Lorentz gas
(Elsevier B.V., 2011-02-15)
Some dynamical properties for a Lorentz gas were studied considering both static and time-dependent boundaries. For the static case, it was confirmed that the system has a chaotic component characterized with a positive ...

Analysing the new Saturnian rings, R/2004 S1 and R/2004 S2
(Springer, 2005-12-01)
The Cassini-Huygens arrival into the Saturnian system brought a large amount of data about the satellites and rings. Two diffuse rings were found in the region between the A ring and Prometheus. R/2004 S1 is coorbital to ...
Role of inducible defenses in the stability of a tritrophic system
(ELSEVIER SCIENCE BV, 2008-06)
Inducible defenses are a form of phenotypic plasticity that potentially modify direct
interactions between various members of an ecological community, generating traitmediated
indirect effects. In this work, the hypothesis ...

Lyapunov exponents and rates of mixing for one-dimensional maps
(Brasil, 2004)
We show that one-dimensional maps f with strictly positive Lyapunov exponents almost everywhere admit an absolutely continuous invariant measure. If f is topologically transitive, some power of f is mixing and, in particular, ...
A stochastic methodology to adjust controllers based on moments Lyapunov exponents: Application to power systems
(2017)
This paper presents a methodology, based on linear analysis, that uses stability indices based on the calculation of moments Lyapunov exponents to determine the optimum adjustment of controllers in linear stochastic systems. ...
