Nonlinear dynamics of a flexible portal frame under support excitation
(2012-12-01)
This paper presents a nonlinear dynamic analysis of a flexible portal frame subjected to support excitation, which is provided by an electro-dynamical shaker. The problem is reduced to a mathematical model of four degrees ...
Some comments on the nonlinear dynamics of a portal frame under base excitation
(IOS Press, 2013-01-01)
This paper presents a nonlinear dynamic analysis of a flexible portal frame subjected to support excitation, which is provided by an electro-dynamical shaker. The main goal of this study is to investigate the dynamic ...
Time evolution of dynamic propensity in a model glass former. The interplay between structure and dynamics
(American Institute of Physics, 2009-01)
By means of the isoconfigurational method we calculate the change in the propensity for motion that the structure of a glass-forming system experiences during its relaxation dynamics. The relaxation of such a system has ...
The dynamics of a mobile phone network
(ELSEVIER SCIENCE BV, 2008)
The empirical study of network dynamics has been limited by the lack of longitudinal data. Here we introduce a quantitative indicator of link persistence to explore the correlations between the structure of a mobile phone ...
Dynamic hedging in Markov regimes
(2008-10-02)
This dissertation proposes a bivariate markov switching dynamic conditional correlation model for estimating the optimal hedge ratio between spot and futures contracts. It considers the cointegration between series and ...
Molecular Dynamics simulations of track formation at different ensembles
(2013-01-01)
A series of Molecular Dynamics simulations of thermal spikes has been run in zircon. For two different ensembles: microcanonical one and a combination of microcanonical one acting on the simulation core with Langevin one ...

Some Results in Stability Analysis of Hybrid Dynamical Systems
(2011)
In this paper we introduced a general model for the Hybrid Dynamical Systems and for such systems we introduced the usual concept of Lyapunov stability. Furthermore, we established two Principal Lyapunov Theorems and a ...
