A contribution for nonlinear structural dynamics characterization of cantilever beams
(2005-12-01)
Successful experiments in nonlinear vibrations have been carried out with cantilever beams under harmonic base excitation. A flexible slender cantilever has been chosen as a convenient structure to exhibit modal interactions, ...
Non-linear energy harvesting system efficiency comparison from periodic to non-ideal excitation
(2014-01-01)
Dynamics of a non-linear energy harvesting is affected by excitation source and to explore efficiency it is necessary to understand which region offers more energy and the influence of a forced periodic vibration related ...
Influence of Excitation Signal on Impedance-based Structural Health Monitoring
(Sage Publications Ltd, 2010-09-01)
The electromechanical impedance (EMI) technique has been successfully used in structural health monitoring (SHM) systems on a wide variety of structures. The basic concept of this technique is to monitor the structural ...
On-line Identification and Convergence Analysis of Excitation -Force and Drag-Force Models for Moored Floating Structures
(Elsevier, 2005-12)
This work presents an approach to identify hydrodynamic models for incident, diffraction and viscous forces acting on a moored floating structure. An important aspect treated here is the analysis of the unknown initial ...
Multi-channel coupling effects for electronic excitations leading to the b(3)Sigma(+)(u), a(3)Sigma(+)(g), and c(3)Pi(u) states of H-2
(John Wiley & Sons IncHobokenEUA, 2006)
Fear, excitement, and financial risk-taking
(Routledge Journals, Taylor & Francis Ltd, 2015-01-02)
Can fear trigger risk-taking? In this paper, we assess whether fear can be reinterpreted as a state of excitement as a result of contextual cues and promote, rather than discourage, risk-taking. In a laboratory experiment, ...
Excited State Absorption of Doped and Undoped Polyanyline
(TAYLOR & FRANCIS LTD, 2010)
Polyaniline is a conducting polymer with appealing electrical and optical properties, arising from the -conjugation along the polymer backbone. The understanding of its excited state absorption is of prime importance for ...
Intersubband excitations at finite temperatures and their roles in different quasi-one-dimensional systems
(Sociedade Brasileira de Física, 2006-06-01)
We theoretically study many-body excitations in three different quasi-one-dimensional (Q1D) electron systems: (i) those formed on the surface of liquid Helium; (ii) in two coupled semiconductor quantum wires; and (iii) Q1D ...
