1. UM CONJUNTO DE PLANILHAS ELETRÔNICAS PARA IDENTIFICAÇÃO E QUANTIFICAÇÃO DE CONSTITUINTES DE ÓLEOS ESSENCIAIS
The identification of essential oils constituents has been made easier and faster by the use of automatic software search engines that compare the experimental mass spectra and calculate the retention indices with those in commercial databases. However, these search engines and databases are very expensive. Electronic sheets have been assembled in a set of l

2. Crescimento facial vertical após a adenotonsilectomia em respiradores orais: O que esperamos é o que encontramos?
Introduction: The association between nasal impairment and dentofacial morphology has been studied for more than a century. Controversies still exist about this subject, despite a lot of information is available on the literature. Therefore, the purpose of this PhD thesis was to evaluate if expectations meet reality regarding some assumptions previously esta

3. Serviços logísticos: influência dos diferentes atributos de qualidade na satisfação e na lealdade dos clientes
This study aimed to identify the different attributes of quality of the logistic services and how these attributes influence the satisfaction and the loyalty of customers that use this service. For that reason, this study took into consideration two estimated results: first, the different attributes of the logistic services influence the satisfaction and loy

4. Desenvolvimento de metodologia experimental para aplicação de espécimes SE(T) para avaliação de integridade estrutural em dutos / Development of an experimental methodology for application of SE(T) specimens for pipeline structural integrity evaluation
Este trabalho apresenta o desenvolvimento e aplicação de espécimes SE(T) em aço API X60 para avaliação de integridade estrutural em dutos condutores de gás e petróleo, o qual consiste na implantação de três técnicas que forneçam as curvas de resistência à propagação dútil de trincas, curvas J-Rs. As metodologias utilizadas foram a da varia�

5. RECONOCIMIENTO DE VOZ EN PRESCENCIA DE RUIDO / SPEECH RECOGNITION IN NOISE ENVIRONMENT / RECONHECIMENTO DE VOZ EM PRESENÇA DE RUÍDO
Este trabalho apresenta um estudo comparativo de três técnicas de melhoria das taxas de reconhecimento de voz em ambiente adverso, a saber: Normalização da Média Cepestral (CMN), Subtração Espectral e Regressão Linear no Sentido da Máxima Verossimilhança (MLLR), aplicadas isoladamente e em concomitância, duas a duas. Os testes são realizados usan

6. REDUÇÃO DE ORDEM DE MODELOS MECÂNICOS LINEARES: UMA ABORDAGEM VIA GRAFOS DE LIGAÇÃO / ORDER REDUCTION OF LINEAR MECHANICAL MODELS: A BOND GRAPH APPROACH
It is described in this work a Bond Graph based procedure to the development of linear mechanical systems reduced order models. From the analysis of the topological structure of the main mechanical models represented by this technique it was established a new formulation that permits to obtain several mathematical representation forms and it was defined a ge

7. Caracterização fluorimetrica da materia organica de origem natural e sua complexação com ions cobre
Marine dissolved organic matter, which has been extracted by adsorption onto SepPak tC18 and, soil fulvic acid processed in the same way, were fractionated by reverse phase high performance liquid chromatography. Based on a stepwise elution gradient, a methodologic procedure was developed using the non-destructive UV-absorption (254 nm) detection system, to

8. Processamento de dados multiespectrais, obtidos por plataformas orbitais da série LANDSAT, para estudos da qualidade da água na Baía de Guanabara / Processing multispectral data obtained by orbital platforms of the LANDSAT series for studies of water quality in Guanabara bay
In this paper we try to establish the grade of relationship existing among various Guanabara Bay water quality parameters and LANDSAT MSS video data. We have chosen an empirical: basis approach, but we had to select, from the available data, some parameters as follows: chlorophyll, water transparency using Secchi disk, salinity and dissolved ammonia. Only tw

9. A new non-linear normalization method for reducing variability in DNA microarray experiments
A simple and robust non-linear method is presented for normalization using array signal distribution analysis and cubic splines. Both the regression and spline-based methods described performed better than existing linear methods when assessed on the variability of replicate arrays

10. Development and Evaluation of Normalization Methods for Label-free Relative Quantification of Endogenous Peptides*
The performances of 10 different normalization methods on data of endogenous brain peptides produced with label-free nano-LC-MS were evaluated. Data sets originating from three different species (mouse, rat, and Japanese quail), each consisting of 35–45 individual LC-MS analyses, were used in the study. Each sample set contained both technical and biologic

12. Issues in cDNA microarray analysis: quality filtering, channel normalization, models of variations and assessment of gene effects
We consider the problem of comparing the gene expression levels of cells grown under two different conditions using cDNA microarray data. We use a quality index, computed from duplicate spots on the same slide, to filter out outlying spots, poor quality genes and problematical slides. We also perform calibration experiments to show that normalization bet
