Impact of reduction of radiometric resolution in hyperspectral images acquired over forest field
(2018-09-20)
The objective of this study was to evaluate the impact of reducing the radiometric information of hyperspectral images. The image data was collected originally with 32 bits and rescaled to 8 and 16 bit/pixel. The images ...
Influence of type 1 diabetes on the symbolic analysis and complexity of heart rate variability in young adultsInfluência do diabetes tipo 1 na análise simbólica e complexidade da variabilidade da frequência cardíaca em jovens adultos
(2018-07-01)
Background: Type 1 diabetes mellitus can cause autonomic changes, which can be assessed by heart rate variability. Among the heart rate variability assessment methods, the symbolic analysis and Shannon entropy, based on ...

(Universidade Federal de Juiz de ForaBrasilFaculdade de EngenhariaPrograma de Pós-graduação em Engenharia ElétricaUFJF, 2016)
Improvement of the signal-to-noise ratio in interferometry using multi-frame high-dynamic-range and normalization algorithms
(ELSEVIER SCIENCE BV, 2012-01-01)
Using both high dynamic range (HDR) and normalization methodologies, we show a method to improve the fringe pattern contrast in interferometric measurements normally used for phase recovering. In a simulated interferogram ...
Impacto da urbanização nas temperaturas do ar e de superfície da região metropolitana de Fortaleza
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM CIÊNCIAS CLIMÁTICAS, 2019-02-25)
The Metropolitan Region of Fortaleza, in the state of Ceará, has an approximate population of
4.051 million inhabitants, more than half of this population is concentrated in Fortaleza. The
increase in urban population ...
Quality evaluation of intact açaí and juçara fruit by means of near infrared spectroscopy
(2016-02-01)
The objective of this study was to report the robustness of partial least squares regression (PLSR) models developed using FT-NIR reflectance spectra obtained from intact açaí and juçara fruit. Mature fruit were collected ...
Lower arm muscle activation during indirect-localized vibration: The influence of skill levels when applying different acceleration loads
(2016-06-16)
We investigated the electromyographic response to synchronous indirect-localized vibration interventions in international and national table tennis players. Twenty-six male table tennis players, in a standing position, ...
Shortwave-near infrared spectroscopy for non destructive determination of maturity of wine grapes
(IOP PUBLISHING LTD, 2003)
Near-infrared (NIR) spectroscopy has become a very popular technique for the non-invasive assessment of intact fruit. This work presents an application of a low-cost commercially available NIR spectrometer for the estimation ...
Using a Multistructural Object-Based LiDAR Approach to Estimate Vascular Plant Richness in Mediterranean Forests With Complex Structure
(IEEE, 2015)
A multistructural object-based LiDAR approach to predict plant richness in complex structure forests is presented. A normalized LiDAR point cloud was split into four height ranges: 1) high canopies (points above 16 m); 2) ...
