Subwavelength twin ultrasound focused (STUF) beam generated by shear-to-longitudinal mode conversion in a triangular prism
(Elsevier, 2022-09-01)
Focusing ultrasound fields in regions below the incident wavelength using elementary objects (such as spherical and cylindrical) as acoustic lenses have been successfully demonstrated over the last five years. This unique ...
Inspeção de materiais compósitos utilizando ondas acústicas guiadas
(Universidade Estadual Paulista (Unesp), 2015-03-28)
In this thesis, a detailed study of ultrasonic non-destructive evaluation in plain woven fabric composite plates is performed. A review of analytical and experimental methods for the de- termination of the characteristic ...

How have daily climate extremes changed in the recent past over northeastern Argentina?
(Elsevier Science, 2018-09)
Changes in climate extremes affect socioeconomics and natural systems in northeastern Argentina (NEA) and may increase its vulnerability leading to unprecedented disasters. This study investigates the long-term changes and ...
Mode-resolved travel-time statistics for elastic rays in three-dimensional billiards
(2014)
System identification is a complex optimization problem which has recently attracted the attention in the field of science and engineering. In particular, the use of infinite impulse response (IIR) models for identification ...

Predictions from an anisotropic inflationary era
(IOP PUBLISHING LTD, 2008)
This paper investigates the predictions of an inflationary phase starting from a homogeneous and anisotropic universe of the Bianchi I type. After discussing the evolution of the background spacetime, focusing on the number ...
Dynamical evolution of anisotropies of the solar wind magnetic turbulent outer scale
(Cambridge Journals, 2012-07)
The evolution of the turbulent properties in the solar wind, during the travel of the parcels of fluid from the Sun to the outer heliosphere still has several unanswered questions. In this work, we will present results of ...
