Damage detection in uncertain nonlinear systems based on stochastic Volterra series
(2018-01-01)
The damage detection problem in mechanical systems, using vibration measurements, is commonly called Structural Health Monitoring (SHM). Many tools are able to detect damages by changes in the vibration pattern, mainly, ...
Damage detection in an uncertain nonlinear beam based on stochastic Volterra series: An experimental application
(2019-08-01)
The damage detection problem becomes a more difficult task when the intrinsically nonlinear behavior of the structures and the natural data variation are considered in the analysis because both phenomena can be confused ...
A compact and high-resolution version of a capacitively coupled contactless conductivity detector
(WILEY-V C H VERLAG GMBH, 2009)
An all-in-one version of a capacitively coupled contactless conductivity detector is introduced. The absence of moving parts (potentiometers and connectors) makes it compact (6.5 cm(3)) and robust. A local oscillator, ...
On the detection of a nonlinear damage in an uncertain nonlinear beam using stochastic Volterra series
(2020-07-01)
In the present work, two issues that can complicate a damage detection process are considered: the uncertainties and the intrinsically nonlinear behavior. To deal with these issues, a stochastic version of the Volterra ...
User extensible system to identify problems in OWL ontologies and SWRL rules
(SpringerCham, 2015)
The Semantic Web uses ontologies to associate meaning to Web content so machines can process it. One inherent problem to this approach is that, as its popularity increases, there is an ever growing number of ontologies ...
Deep Texture Features for Robust Face Spoofing Detection
(2017-12-01)
Biometric systems are quite common in our everyday life. Despite the higher difficulty to circumvent them, nowadays criminals are developing techniques to accurately simulate physical, physiological, and behavioral traits ...
Local search multiuser detection
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2009)
In this work, a wide analysis of local search multiuser detection (LS-MUD) for direct sequence/code division multiple access (DS/CDMA) systems under multipath channels is carried out considering the performance-complexity ...

Unsupervised fuzzy-wavelet framework for coastal polynya detection in synthetic aperture radar images
(Taylor & Francis, 2016-07)
The automated detection of coasts, riverbanks, and polynyas from synthetic aperture radar images is a difficult image processing task due to speckle noise. In this work we present a novel Fuzzy-Wavelet framework for bordeline ...
