A simulation method for determining the optical response of highly complex photonic structures of biological origin
(Cornell University, 2013-01)
We present a method based on a time domain simulation of wave propagation that allows studying the optical response of a broad range of dielectric photonic structures. This method is particularly suitable for dealing with ...
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, ...

Rayleigh method adapted for the study of the optical response of natural photonic structures
(Springer, 2021-09-23)
To study the electromagnetic response of natural structures that exhibit interesting optical properties, we developed a computational tool to solve the problem of electromagnetic scattering by a rough interface between two ...
Automation in fault detection using neural network and model updating
(1999-03-01)
In this article, an implementation of structural health monitoring process automation based on vibration measurements is proposed. The work presents an alternative approach which intent is to exploit the capability of model ...
Multistratum response surface designs
(Amer Statistical Assoc, 2001-02-01)
Response surface designs are usually described as if the treatments have been completely randomized to the experimental units. However, in practice there is often a structure to the units, implying the need for blocking. ...
Inelastic deformation response of SDOF systems subjected to earthquakes
(2002-03)
Performance-based seismic design requires reliable methods to predict earthquake demands on structures, and particularly inelastic deformations, to ensure that specific damage-based criteria are met. Several methods based ...
Ab initio study of the role of defects on the magnetic response and the structural, electronic and hyperfine properties of ZnFe2O4
(Elsevier Science SA, 2019-02-15)
In this work the effects of defects (oxygen vacancies, cationic inversion) on the structural, electronic and the magnetic response of the spinel ZnFe2O4 (ZFO) are studied by using a density functional theory (DFT) based ...
Time-domain electromechanical impedance for Structural Health Monitoring
(2011-01-01)
Electromechanical impedance (EMI) technique is a very simple method that can be usefulness in most of Non-Destructive Evaluation (NDE) and Structural Health Monitoring (SHM) systems. A common application of EMI methods is ...
