The investigation of α→β phase transition in poly(vinylidene fluoride) (PVDF)
(2005-12-01)
The phase transition from the non-polar α-phase to the polar β-phase of poly(vinylidene fluoride) (PVDF) has been investigated using micro-Raman spectroscopy, which is advantageous for being a non-destructive technique. ...
Designing artificial neural networks for band structures computations in photonic crystals
(2019-01-01)
We modeled Multilayer Perceptron and Extreme Learning Machine Artificial Neural Networks (ANNs) for computing band structures (BSTs) and photonic band gaps (PBGs) of 2D and 3D photonic crystals (PhCs). We aim at providing ...
Multilayer Perceptron Models for Band Diagram Prediction in bi-dimensional Photonic Crystals
(2019-01-11)
We modeled Multilayer Perceptron (MLP) Artificial Neural Network for predicting band diagrams (BD) of bi-dimensional photonic crystals. Datasets for MLP training were created by relating geometric and material properties ...

Ultrabroadband Wavelength Conversion with Tellurite Waveguides
(2021-01-01)
In this work, we propose and investigate numerically a two-stage one-pump four-wave mixing (FWM) device for guard-band-less wavelength conversion. This device can convert all signals within the C-band to the L-band and, ...
Tie point generation in hyperspectral cubes for orientation with polynomial models
(2019-01-01)
This paper presents a technique for tie point generation in hyperspectral images collected by a camera with time-sequential principle for band acquisition (i.e., non-synchronized bands). In mobile applications, each band ...
Performance evaluation of sequential band orientation by polynomial models in hyperspectral cubes collected with uav
(2019-06-04)
A study on orientation of hyperspectral band cubes acquired with frame camera is presented in this paper. The camera technology is based on a tuneable Fabry-Perot Interferometer (FPI) and captures cubes of images sequentially ...
Estimating exterior orientation parameters of hyperspectral bands based on polynomial models
(2017-10-19)
Hyperspectral camera operating in sequential acquisition mode produces spectral bands that are not recorded at the same instant, thus having different exterior orientation parameters (EOPs) for each band. The study presents ...
Refining the geometric calibration of a hiperspectral frame camera with preliminary bands coregistration
(2018-10-31)
Lightweight hyperspectral sensors carried by unmanned aerial vehicles (UAV) are becoming powerful remote sensing tools for several applications, e.g., forestry and agriculture. Sequential frame acquisition by scanning the ...
