Laser interference fringe tomography (LIFT) is within the class of optical imaging devices designed for volumetric microscope applications. LIFT is a very simple and cost-effective three-dimensional imaging device which is able to reliably produce low-quality imagery. It measures the reflectivity as a function of depth within a sample and is capable of producing three-dimensional images from optically scattering surfaces. The first generation of this instrument is designed and prototyped for optical microscopy. With an imaging spot size of 42 μm and a 180 μm axial resolution kernel, LIFT is capable of producing one- and two- dimensional images of various samples up to 1.5 mm thickness. The prototype was built using commercial-off-the-shelf components and cost ~ $1,000. It is possible that with effort, this device can become a reliable, stable, low-quality volumetric imaging microscope to be readily available to the consumer market at a very affordable price. This document will present the optical design of LIFT along with the complete mathematical description of the instrument. The design trade-offs and choices of the instrument are discussed in detail and justified. The theoretical imaging capabilities of the instrument are tested and experimentally verified. Finally, some imaging results are presented and discussed.

The systematic study of orchestral practice and instrumentation in the German Baroque Opera has until now been assigned a relatively insignificant place in biographies of specific composers, or in historical studies of particular centres. Many of these works, while presenting a valuable compilation of the instrumental methode of a particular composer, or of the adoption of his style to meet the conditions of performance which prevailed from one centre to another, do not however supply their readers with a chronogically exhaustive investigation of the role of the orchestra in the baroque theatre, nor of the contribution made by theatre orchestration of the general artistic development of orchestral music as a whole.

Foram avaliados instrumentos S1, S2, F1, F2 e F3 pertencentes ao Sistema ProTaper Universal (Dentsply/Maillefer) sendo 20 de cada número num total de 100 instrumentos, que foram divididos em dois grupos. Todos os instrumentos foram submetidos a ensaio de flexão por meio de um dispositivo elaborado especificamente para este estudo. O aparato para teste foi composto por um canal artificial curvo, fabricado em aço inoxidável temperado e que apresentava 5mm de raio e ângulo de curvatura de 45º. Um motor elétrico X-Smart (Dentsply/Maillefer) com um contra-ângulo com redução de 16:1 foi regulado para trabalhar à uma velocidade constante de rotação de 300rpm e com um torque de 2 N.cm. A este contraângulo foram acoplados os instrumentos ProTaper Universal que foram introduzidos no canal artificial e ali giraram livremente até sua fratura. O aparato regulava a velocidade de deslocamento axial do canal artificial para frente e para trás, na direção dos instrumentos, simulando a entrada e saída dos instrumentos no canal radicular. Foram utilizadas duas velocidades de deslocamento do canal simulado, sendo que os instrumentos do Grupo I foram submetidos à uma velocidade mais lenta (146 deslocamentos por minuto) e no Grupo II a velocidade foi mais rápida (189/min). O tempo até a fratura foi registrado por um cronômetro e, a partir daí, encontrou-se o número de rotações para fratura. A comparação do número médio de ciclos até a fratura foi realizada por meio do teste t de Student para amostras independentes. Os resultados mostraram que ocorreu diferença estatisticamente significante do número médio de ciclos até a fratura apenas para o instrumento F3 (p=0,025)...

The S1, S2, F1, F2 and F3 instruments from the ProTaper Universal System (Dentisply/Maillerfer) were evaluated. Twenty samples of each instrument, totalizing 100 samples, were divided in two groups. All instruments were submitted to the flexure strength test using a device specially developed for this study. The device was composed by a 45º sloped artificial root canal, made with tempered stainless steel, with radius of 5mm. An X-Smart (Dentisply/Maillefer) electric engine that had a contra-angle with rotatory reduction of 16:1 was stated to work with a constant speed of 300rpm and with a torque of 2N.cm. Each ProTaper Universal Instrument was individually attached to the contra-angle and then introduced into the artificial root canal where they rotate freely until failure. The test apparatus also has a potentiometer that was responsible to regulate the axial dislodgment speed of the artificial root canal forward and backward, against instruments direction, simulating the inward and the outward movement of the instruments into the real root canal. Two displacements speeds of the simulated root canal were used, so that the instruments in Group I were submitted to the slower speed (146 displacements per minute - d/min) and in Group 2 to the faster speed (189d/min). The time elapsed until failure of the instruments was chronometrically measured and registered; then, the number of rotations was calculated from this measurement. The comparison between the mean numbers of cycles until failure was done by the T-Student test. The results of this study showed statistically significant differences in the mean number of cycles until failure only for the F3 instrument (p=0.025). In Group I it was found about 201 fewer cycles... (Complete abstract click electronic access below) / Doutor

Esta dissertação trata do projeto e avaliação de um canal de medição de bioimpedâncias multifrequencial cujo objetivo é a medida em módulo e fase de impedâncias até 1 k com desempenho reportado nas freqüências 100 kHz, 300 kHz e 1 MHz. Um modelo teórico foi desenvolvido para cada etapa do canal de medição incluindo as não idealidades dos componentes utilizados na implementação prática. A análise da sensibilidade à variação de parâmetros e da propagação de incertezas nas etapas do sistema foi realizada juntamente com a avaliação experimental da exatidão e precisão do protótipo desenvolvido. O circuito proposto apresenta incerteza experimental 0,008% nas medidas de amplitude e 0,05% nas medidas de fase. / This dissertation deals with the project and evaluation of a multifrequency bioimpedance measurement channel whose objective is to obtain the measure in module and phase of load impedances up to 1 k with performance reported in 100 kHz, 300 kHz and 1 MHz. A theoretical model was developed for each stage of the measurement channel having included non-idealities of the components used in the practical implementation. The sensitivity analysis with respect to parameter variation and uncertainty analysis in the stages of the system was carried through together with the experimental evaluation of the accuracy and precision of the developed prototype. The considered circuit presents experimental uncertainty of 0.008% in the measures of amplitude and 0.05% in the measures of phase.

Atualmente, a avaliação da tonicidade de bochechas é realizada de forma perceptual e dependente da experiência do avaliador. Por esse motivo, este trabalho propôs uma alternativa para diminuir a subjetividade da forma de avaliação atual da força das bochechas, a qual pode complementar o diagnóstico fonoaudiológico. Desenvolveu-se um protótipo constituído de uma célula de carga acoplada a uma haste, sistema de conversão, amplificação e transmissão do sinal elétrico. Um estudo inicial buscou avaliar a repetitividade e reprodutibilidade de medições realizadas em sujeitos normais e alterados quanto à força das bochechas. Num segundo estudo visou-se quantificar e analisar a performance de indivíduos com força adequada. Os valores de força no sexo masculino, tanto para força média quanto para força máxima, foram estatisticamente maiores do que os valores entre o sexo feminino. Cinco tipos de curva caracterizam o comportamento da bochecha durante o ensaio. O método de avaliação quantitativa da força das bochechas desenvolvido colaborou para a diminuição da subjetividade da avaliação e foi capaz de registrar a força exercida pelas bochechas. / Currently clinical evaluation of cheeks tone is performed at a perceptual level and depends on the evaluator's experience. Therefore, this study aimed to propose an alternative way of reducing the subjectivity in cheeks strength assessments, which can complement the speech therapist diagnosis. We developed a prototype consists of a load cell coupled to a handle, the conversion system, amplification, and the electrical signal transmission. An initial study was toanalyze of repeatability and reproducibility of measurements performed in normal and abnormal individuals regarding cheek strength. In a second study sought to quantify and analyze the performance of subjects with adequate strength. The force values in males, both for strength and for average maximum force were statistically higher than the values among females. Five types of curve characterize the behaviour of the cheek during the test. The method of quantitative assessment of the cheeks strength developed helped to reduce the subjectivity of the evaluation and it was able to record the force exerted by the cheeks.
