Multiphysics modeling, experimental validations and building implementation of viscous fluid dampers
(National Information Centre of Earthquake Engineering, 2017)
The scope of this article is the design, testing, implementation and health-monitoring of viscous fluid dampers in a real building. First, a numerical model that captures the complex fluid dynamics and thermal behavior of ...
Study of the fractality of magnetized plasma using an MHD shell model driven by solar wind data
(American Institute of Physics Inc., 2018)
An MHD shell model is used to describe the dissipative events that take place in magnetized plasmas. We analyze the activity of the time series of the magnetic energy dissipation rate obtained in the MHD shell model, which ...
Dissipative nonlinear waves: fronts in heterogeneous media
(2019)
This dissertation is devoted to the understanding of the dynamics of fronts that exhibit coexistence between stable and unstable state in heterogeneous media. With this purpose, we initiated our investigation with a simple ...
Design, testing and implementation of TADAS devices in three RC buildings with shear walls and coupling beams
(2017)
A Triangular Added Damping and Stiffness (TADAS) device is an economic energy dissipation solution to improve the earthquake performance of flexible buildings. TADAS devices have a very stable force displacement constitutive ...
Non-uniform drag force on the Fermi accelerator model
(Elsevier B.V., 2012-11-15)
Some dynamical properties of a particle suffering the action of a generic drag force are obtained for a dissipative Fermi Acceleration model. The dissipation is introduced via a viscous drag force, like a gas, and is assumed ...

Dissipative structures induced by spin-transfer torques in nanopillars
(American Physical Society, 2014)
Macroscopic magnetic systems subjected to external forcing exhibit complex spatiotemporal behaviors as
result of dissipative self-organization. Pattern formation from a uniform magnetization state, induced by the
combination ...
Alternating spin-polarized current induces parametric resonance in spin valves
(American Physical Society, 2015)
Ferromagnetic systems under the influence of spin-polarized currents exhibit rich spatiotemporal dynamics at nanoscales. We study spin-transfer nano-oscillators driven by the combination of alternating and direct spin-polarized ...
A symmetry break in energy distribution and a biased random walk behavior causing unlimited diffusion in a two dimensional mapping
(2015-07-21)
We have shown that a break of symmetry of the probability distribution and a biased random walk behavior lead the dynamics of a two dimensional mapping to present unlimited diffusion. The mapping considered describes the ...
