1. Acoplamento de técnicas espectrométricas com métodos quimiométricos de classificação e calibração multivariada em alimentos / Coupling spectrometric techniques with chemometric methods for classification and multivariate calibration in food
This research work describes three studies of chemometric methods employed for the classification and characterization of edible oils and its quality parameters through Fourier Transform mid infrared spectroscopy and near infrared spectroscopy, and for the monitoring the oxidative stability and quality of yogurt using fluorescence spectroscopy . The first an

2. Calibração multivariada de primeira e segunda ordem e figuras de merito na quantificação de enantiomeros por espectroscopia / First and second order multivariate calibration and figures of merit in the quantification of enantiomers by spectroscopy
First and second order multivariate calibration were developed for the quantification of enantiomers by spectroscopy and b-cyclodextrin guest-host complexes. In the first case, first order multivariate calibration was employed based on partial least square regression (PLS) for the quantification of the chlorpheniramine maleate enantiomers by ultraviolet (UV)

3. Estado da arte de figuras de mérito em calibração multivariada
The validation of an analytical procedure must be certified through the determination of parameters known as figures of merit. For first order data, the acuracy, precision, robustness and bias is similar to the methods of univariate calibration. Linearity, sensitivity, signal to noise ratio, adjustment, selectivity and confidence intervals need different app

4. PARAFAC: uma ferramenta quimiométrica para tratamento de dados multidimensionais. Aplicações na determinação direta de fármacos em plasma humano por espectrofluorimetria
Since the last decade, the combined use of chemometrics and molecular spectroscopic techniques has become a new alternative for direct drug determination, without the need of physical separation. Among the new methodologies developed, the application of PARAFAC in the decomposition of spectrofluorimetric data should be highlighted. The first objective of thi

5. Algoritmo genetico na seleção de variaveis em calibração multivariada de dados espectroscopicos
This work describes the development and application of genetic algorithm in variable selection of spectroscopic data in multivariate calibration. The genetic algorithm is based on Darwin evolution theory, and in last years has increase the interest in the scientific community .A program for calculations was developed in MATLAB language. For program evaluatio
