Ultrasonic material characterization using large-aperture PVDF receivers
(ELSEVIER SCIENCE BV, 2010)
This work describes the use of a large-aperture PVDF receiver in the measurement of liquid density and composite material elastic constants. The density measurement of several liquids is obtained with accuracy of 0.2% using ...

Automatic design of aperture filters using neural networks applied to ocular image segmentation
(European Association for Signal Processing, 2014-09)
Aperture filters are image operators which combine mathematical morphology and pattern recognition theory to design windowed classifiers. Previous works propose designing and representing such operators using large decision ...
Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
(2013-06-01)
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...

Remote sensing of wetland types: Subtropical wetlands of southern hemisphere
(2018-05-16)
The Pantanal is a large cross-border wetland system in South America that supports a diversity of ecosystems. This internationally important wetland is under threat from water diversion but also agricultural development ...
Exploring the Capability of ALOS PALSAR L-Band Fully Polarimetric Data for Land Cover Classification in Tropical Environments
(Ieee-inst Electrical Electronics Engineers Inc, 2016-12-01)
Among different applications using synthetic aperture radar (SAR) data, land cover classification of rain forest areas has been investigated. Previous results showed that L-band is more appropriate for such applications. ...
