1. Implementação de um método robusto para o controle fiscal de umidade em queijo minas artesanal. Abordagem metrológica multivariada
This study developed and validated a method for moisture determination in artisanal Minas cheese, using near-infrared spectroscopy and partial-least-squares. The model robustness was assured by broad sample diversity, real conditions of routine analysis, variable selection, outlier detection and analytical validation. The model was built from 28.5-55.5% w/w,

3. AVALIAÇÃO METROLÓGICA DA INCERTEZA NA MEDIÇÃO DE VAZÃO MÁSSICA DE GASES COM TECNOLOGIAS VOLUMÉTRICA E PRESSÃO DIFERENCIAL / Avaliação metrológica da incerteza na medição de vazão mássica de gases com tecnologias volumétrica e pressão diferencial
In despite of the metrological evaluation of the measurement uncertainty have been internationally standardized (ISO-GUM, 1995) since the mid of the nineties, only now it?s getting popular in the industries, technical and engineering schools. In some fields like dimensional metrology it is advanced, while in others like in the process measurement industries

6. METROLOGICAL RELIABILITY OF LUNG VENTILATORS / CONFIABILIDADE METROLÓGICA DE VENTILADORES PULMONARES
The present Masters dissertation evaluates the metrological reliability of pulmonary ventilators, also known as mechanical ventilators. Pulmonary ventilators are electromedical equipment (EEM). The absence of metrological reliability of a pulmonary ventilator may result in dangerous consequences, according to its classification by the potential risk to the h

9. Avaliação do processo de cicatrização de lesões, tratadas com laser de baixa intensidade, através de sistema de aquisição e tratamento de imagem
Wound healing is a complex dynamic process characterized as a sequence of responses from several types of cells (epithelial, inflammatory, blood platelet, and fibroblasts) that interact to restore tissue complexion. It starts right after occurring an injury with an inflammatory stage, which is followed by granulation and, finally, by epithelization. Several

10. METROLOGICAL RELIABILITY OF HIGH FREQUENCY SURGICAL EQUIPMENT / CONFIABILIDADE METROLÓGICA DE UNIDADES ELETROCIRÚRGICAS DE ALTA FREQÜÊNCIA
The metrological reliability of electromedical equipment, although essential in order to guarantee the desired effects and to avoid adverse effects, is often not verified after the equipment is sold and being used (post-sale period). This is partially due to the fact that, usually, health-care takers that use the equipment are unaware of the risks involved,

11. AVALIAÇÃO METROLÓGICA DE ACELERÔMETRO ÓPTICO UTILIZANDO REDE DE BRAGG: APLICAÇÃO EM LINHAS DE TRANSMISSÃO DE ENERGIA ELÉTRICA / METROLOGICAL EVALUATION OF AN OPTICAL FIBER BRAGG GRATING ACCELEROMETER: APPLICATION IN OVERHEAD TRANSMISSION LINES
Overhead transmission lines play an important role on electric systems. Due to the high energy carried through those networks, failures on overhead lines can bring severe constraints on consumers supply, occasionally taking the form of blackouts in large geographic regions. Among the reasons of such failures is the breaking of electric cables caused by the f

12. METODOLOGIA PARA AVALIAÇÃO METROLÓGICA DE CARACTERÍSTICAS DE UM TERMISTOR PTC POLIMÉRICO REGENERATIVO / METHODOLOGY FOR METROLOGICAL EVALUATION OF THE CHARACTERISTICS OF A PTC POLYMERIC RESETTABLE THERMISTOR
This research aims at the development of a methodology for experimentally characterizing a PTC polymeric resettable thermistor LP60-110, used as an overcurrent and over temperature protection device. Uncertainty of measurement of the parameters, such as temperature, voltage, current and ohmic resistance is also determined. The PTC (Positive Temperature Coeff
