Internal inspection of semi-transparent objects by digital holographic micro-tomography
(Elsevier Gmbh, 2013-09)
The combined use of digital holographic microscopy and computer tomography, here named digital holographic micro-tomography, is used to examine the interior of transparent channels. The proposed method is used to identify ...
Use of simple non-destructive techniques to evaluate the hydration reactions of PVA-modified cement pastes
(Elsevier, 2017-02)
The rapidity of the hydration reaction defines the final properties of cement-based materials. Global techniques show the overall hydration reaction and make it easier for users to evaluate it in a simple non-destructive ...
Identification of steel bars immersed in reinforced concrete based on experimental results of eddy current testing and artificial neural network analysis
(2013-03-01)
This paper presents an experimental research on the use of eddy current testing (ECT) and artificial neural networks (ANNs) in order to identify the gauge and position of steel bars immersed in concrete structures. The ...

Infrared Thermography technique (IRT) for the evaluation of the hydric behavior of building stones
(IMEKO-ACTA, 2018-10)
The water distribution into stone specimens in laboratory conditions is evaluated through the infrared thermography method (IRT). Porous building stones samples (calcarenite and sandstone) are examined under stable laboratory ...
Hybridization effect on the mechanical properties of curaua/glass fiber composites
(2013-08-20)
The aim of this paper was to evaluate the effect of hybridizing glass and curaua fibers on the mechanical properties of their composites. These composites were produced by hot compression molding, with distinct overall ...

Bending stiffness evaluation of Teca and Guajara lumber through tests of transverse and longitudinal vibration
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAOMARINGA, 2012)
The grading of structural lumber besides contributing for increasing the structure's safety, due to the reduction of the material variability, also allows its rational use. Due to the good correlation between strength and ...
