Instantaneous frequency measurement by in-fiber 0.5th order fractional differentiation
(Elsevier Science, 2016-07)
We experimentally demonstrate the possibility to retrieve the instantaneous frequency profile of a given temporal light pulse by in-fiber fractional order differentiation of 0.5th-order. The signal's temporal instantaneous ...
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 ...

Influence of fiber volume fraction and aspect ratio in Resol-Sisal composites
(John Wiley & Sons Inc, 2003-06)
Vegetable fibers are being used as reinforcements in polymeric matrices with a wide variety of applications. Among these fibers, sisal is of particular interest due to the high impact strength and moderate tensile and ...
The distribution of lignin and xylan in the inner and surface layers of the fiber from eucalyptus kraft pulp and its effects on oxygen delignification
(2017-07-01)
The chemical structure and composition of lignin and hemicellulose, as well as the distribution between inner and outer layers of fiber, can adversely affect bleaching operations or fiber-fiber bond on pulp and, consequently ...
Can the maximum volume fraction ensure optimum reinforcement in short-fiber composites?
(John Wiley & Sons Inc, 2019-08)
Short sisal fiber composites (SSFCs) based on a pectin matrix were prepared and characterized mechanical and optically. Different concentrations (1–30 wt %) of fibers were used to evaluate the packing effect on the ...
Photonic fractional Fourier transformer with a single dispersive device
(Optical Society Of America, 2013-04)
In this work we used the temporal analog of spatial Fresnel diffraction to design a temporal fractional Fourier transformer with a single dispersive device, in this way avoiding the use of quadratic phase modulators. We ...
Experimental demonstration of fractional order differentiation using a long-period grating-based in-fiber modal interferometer
(Elsevier Science, 2016-12)
In this work we demonstrate both, experimentally and theoretically, that a long-period grating-based in-fiber modal interferometer can perform an all-optical arbitrary-order fractional differentiation. Experimentally, we ...
