On the dynamic behaviour of a nonlinear system weakly connected to a linear single degree-of-freedom system
(2011-12-01)
This paper discusses the dynamic behaviour of a nonlinear two degree-of-freedom system consisting of a harmonically excited linear oscillator weakly connected to a nonlinear attachment that behaves as a hardening Duffing ...

Fast-frequency response provided by DFIG-wind turbines and its impact on the grid
(2017)
This paper presents a methodology for the analysis of frequency dynamics in large-scale power systems with high level of wind energy penetration by means of a simplified model for DFIG-based wind turbines. In addition, a ...
On the response at the excitation frequency of a two degrees of freedom nonlinear oscillator
(2017-01-01)
This paper presents an overview of the main theoretical advances and experimental analyses, achieved by the authors in recent years of collaborative research in the field of nonlinear dynamics of coupled oscillators. The ...
An alternative method based on RF to classify porous ceramic materials
(Institute of Electrical and Electronics Engineers Inc., 2018)
Several properties of ceramic materials such as mechanical strength, acoustical characteristics, etc. are related to their degree of porosity. Traditional methods to estimate the porosity of materials used in construction ...
