Forward and backward aortic components and reflection indexes in children and adolescents: Determinants and role in high pressure states
(Bentham Science Publishers, 2018-04)
Background: High blood pressure states (HBP) would differ in wave components and reflections indexes, which could associate clinical and prognostic implications. The study aims: 1) to characterize the association of aortic ...
Acousto-optic modulation of optical reflection properties in fiber Bragg gratings and the application in fiber lasers
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2015-09-11)
This thesis aims to investigate the interaction of acoustic waves and fiber Bragg gratings (FBGs) in standard and suspended-core fibers (SCFs), to evaluate the influence of the fiber, grating and modulator design on the ...

Ultrasonic inspection of AA6013 laser welded joints
(ABM, ABC, ABPol, 2011-09-01)
Interest in laser beam welding for aerospace applications is continuously growing, mainly for aluminum alloys. The joints quality is usually assessed by non-destructive inspection (NDI). In this work, bead on plate laser ...
Propagation of Gaussian beams through active layers
(Society of Photo-Optical Instrumentation Engineers, 2013-07)
Knowledge of propagation, transmission and reflection properties of space- and time-limited beams is relevant to the classical description of electromagnetic field modes in laser and other optoelectronic devices. For many ...
Detection of damage in structural waveguides using high frequency waves
(Universidade Estadual Paulista (Unesp), 2015-04-28)
Wave propagation research for Structural Health Monitoring (SHM) has been increasing recently. It allows the detection of damage at its early stages of development. This dissertation describes a theoretical study of wave ...
