Phantom solution in a non-linear Israel-Stewart theory
(2017)
In this paper we present a phantom solution with a big rip singularity in a non-linear regime of the Israel-Stewart formalism. In this framework it is possible to extend this causal formalism in order to describe accelerated ...
Macroscopic approximation to relativistic kinetic theory from a nonlinear closure
(American Physical Society, 2013-02-04)
We use a macroscopic description of a system of relativistic particles based on adding a nonequilibrium tensor to the usual hydrodynamic variables. The nonequilibrium tensor is linked to relativistic kinetic theory through ...
Optimal linear and nonlinear control design for chaotic systems
(2005-12-01)
In this work, the linear and nonlinear feedback control techniques for chaotic systems were been considered. The optimal nonlinear control design problem has been resolved by using Dynamic Programming that reduced this ...

Monotone positive solutions for a fourth order equation with nonlinear boundary conditions
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This work is concerned with the existence of monotone positive solutions for a class of beam equations with nonlinear boundary conditions. The results are obtained by using the monotone iteration method and they extend ...
Periodic pulses of coupled nonlinear Schrodinger equations in optics

Poincaré plot indexes of heart rate variability: Relationships with other nonlinear variables
(2013-10-01)
The Poincaré plot for heart rate variability analysis is a technique considered geometrical and non-linear, that can be used to assess the dynamics of heart rate variability by a representation of the values of each pair ...

Comparative analysis for reactive energy measurement methodologies, under non-sinusoidal conditions in three-phase four-wire circuits
(2011-12-28)
This paper presents some methodologies for reactive energy measurement, considering three modern power theories that are suitable for three-phase four-wire non-sinusoidal and unbalanced circuits. The theories were applied ...
