ATR-FTIR spectroscopy and multivariate analysis for thermal burned skin classification
(Washington, DC, USA: OSA, 2017)
Fractal descriptors in the Fourier domain applied to color texture analysis
(American Institute of Physics - AIPCollege Park, 2011-12)
The present work proposes the development of a novel method to provide descriptors for colored texture images. The method consists of two steps. First, we apply a linear transform in the color space of the image aiming at ...

Study of coprolites from the araripe sedimentary basin through FT-IR spectroscopy and X-ray diffraction
(Soc Brasileira Quimica, 2007-01-01)
Coprolites are fossilized faeces that constitute an important source of palaeobiological informations. This paper describes the characterization of some coprolite materials originated from the Romualdo Member of the Santana ...
Experimental NMR and MS study of benzoylguanidines. Investigation of E/Z isomerism
(2013-04-01)
Molecules containing the guanidinic nuclei possess several pharmacological applications, and knowing the preferred isomers of a potential drug is important to understand the way it operates pharmacologically. Benzoylguanidines ...
Comparative study of wine tannin classification using Fourier transform mid-infrared spectrometry and sensory analysis
(SOC APPLIED SPECTROSCOPY, 2007)
Wine tannins are fundamental to the determination of wine quality. However, the chemical and sensorial analysis of these compounds is not straightforward and a simple and rapid technique is necessary. We analyzed the ...
