A study on the effects of viewing angle variation in sugarcane radiometric measuresEstudo do efeito da variação no ângulo de visada em medidas radiométricas na cana-de-açúcar
(2018-01-01)
Remote Sensing techniques, such as field spectroscopy provide information with a large level of detail about spectral characteristics of plants enabling the monitoring of crops. The aim of this study is to analyze the ...
Spectral Analysis of Incoherent Scatter Radar Signals in Faraday/Double Pulse Experiments at the Jicamarca Radio Observatory
(IEEE, Institute of Electrical and Electronics Engineers, 2021)
The Jicamarca incoherent scatter radar can be operated in different modes to measure the main physical parameters of the equatorial ionosphere. One of these modes is the Faraday/Double Pulse experiment that was designed ...
Longitudinal study of the spectral composition of behavioral rhythms in the rat
(Taylor & Francis Ltd, 2005-02-01)
Four. male Wistar rats were housed in pairs of siblings, on LD 12:12h and 22 degrees C + 2 degrees C. Food and water were provided ad libitum. Behavior was videotaped from the 1st to the 3rd month of life. In each age-bracket ...

Spectral parameter estimation of CAT radar echoes in the presence of fading clutter
(American Geophysical Union, 1982-07)
The 430 MHz, 2 MW radar at the Arecibo Observatory is currently being used as a stratospheric-troposheric (ST) radar. One of the problems in the automatic analysis of the signals come from the very large amplitude of the ...
A procedure for overlapping deconvolution and the determination of its confidence interval for arsenic and lead signals in TXRF spectral analysis
(Wiley, 2013-01)
We studied the applicability and validity range of a mathematical procedure on the basis of the principia of maximum likelihood for the identification and quantification of arsenic and lead. This procedure has showed to ...
