Damage detection through nonparametric models using Kautz filters
(2021-05-01)
The goal of this paper is to present an approach to detect structural changes by using nonparametric models. The impulse response functions (IRFs) of mechanical systems in healthy conditions are identified through the sum ...
Free and forced wave motion in a two-dimensional plate with radial periodicity
(2021-11-01)
In many practical engineering situations, a source of vibrations may excite a large and flexible structure such as a ship’s deck, an aeroplane fuselage, a satellite antenna, a wall panel. To avoid transmission of the ...
A numerical investigation on the visco-plastic response of structures to different pulse loading shapes
(ELSEVIER SCI LTD, 2008)
The time varying intensity character of a load applied to a structure poses many difficulties in analysis. A remedy to this situation is to substitute a complex pulse shape by a rectangular equivalent one. It has been shown ...
Bayesian model identification of higher-order frequency response functions for structures assembled by bolted joints
(2021-04-01)
This paper proposes a procedure to identify a stochastic Bouc-Wen model for describing the dynamics of a structure assembled by bolted joints considering vibration data. The proposed identification approach is expressed ...

Influence of microwave energy on structural and piezoelectric response of Bi 4Ti 3O 12 ceramics
(2010-12-01)
Bismuth titanate ceramics (Bi 4Ti 3O 12) with 10 wt% in excess of bismuth (BIT10) were prepared by the polymeric precursor method and sinterized in microwave (MW) and conventional furnaces (CF). The effect of microwave ...
Correlation among immune response, morphogenesis of the granulomatous reaction and spleen lymphoid structure in murine experimental paracoccidioidomycosis
(B I O S Scientific Publishers Ltd, 2000-10-01)
We studied the correlation among cellular immune response, the pattern of lung granulomatous lesions and alterations in spleen lymphoid structure in Swiss mice inoculated intravenously with Paracoccidioides brasiliensis ...
Enhanced method for determining the optical response of highly complex biological photonic structures
(Optical Society of America, 2013-09)
We present a set of techniques that enhances a previously developed time domain simulation of wave propagation and allows the study of the optical response of a broad range of dielectric photonic structures. This method ...
