No. of bitstreams: 1 dissertacao_luis_carlos_barbosa.pdf: 750410 bytes, checksum: a3669bd0c4d5d28d860b57479508f874 (MD5) Previous issue date: 2005-02-18 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This research aimed the investigation of the meta resources, used by a linear algebra professor in a classroom, helping his students to better understand the notions of basis. To achieve this, the classes were watched and recorded, in order to get and analyze the observed meta resources. The theory used in the meta resources analysis was the meta lever from Jean Luc Dorier and Aline Robert, and the three principles for teaching and learning from Guershon Harel. An interview guide was elaborated and applied in a sample of students who participated in the research, with the intention of evaluating if any of the selected resources would become a meta lever for the students. As a result, it was concluded that only one of the selected resources became a meta lever for most of the interviewed students / Esta pesquisa teve como objetivo investigar os recursos-meta, utilizados por um professor de Álgebra Linear, em sala de aula, que ajudaram alguns de seus alunos na compreensão da noção de base. Para tanto, essas aulas foram assistidas e audiogravadas para se levantar e analisar os recursos-meta observados. A teoria utilizada na analise dos recursos-meta foi a Alavanca-Meta de Jean Luc Dorier e Aline Robert e os três princípios para o ensino e a aprendizagem de Guershon Harel. Elaborou-se um guia de entrevista semi-estruturada que foi aplicado em uma amostra de alunos participantes do estudo, com o intuito de observar se algum dos recursos selecionados tornou-se alavanca-meta aos alunos. Como resultado, constatou-se que apenas um dos recursos selecionados tornou-se alavanca-meta para a maioria dos alunos entrevistados Álgebra linear Base Recursos-meta Alavanca-meta Sala de aula Entrevista Educacao matematica Matematica -- Estudo e ensino Algebra linear Linear algebra Basis Meta resources Meta lever Classroom Interview
86	Design Of Two-Axis Displacement-Amplifying Compliant Mechanisms Using Topology Optimization Dinesh, M 01 July 2008 (has links) This thesis deals with the design of two-axis displacement-amplifying compliant mechanisms (DaCMs) using topology optimization. The two-axis compliant mechanisms considered here are XY positioners and two-axis inertial sensors. A building block approach, with several single-axis DaCMs as building blocks, is used to conceive designs of compliant platforms that provide two orthogonal and independent movement of a common platform. Spring-mass-lever (SML) models of these designs are developed to simplify the analysis and design of the complicated arrangements of building blocks. The XY positioners designed in this work have perfectly de-coupled motion without compromising on the frequency; the best design of the stage has a displacement amplification of five resulting in the enhanced range of 4.2 % of the mechanism size–a significant improvement from the 1.67 %, the maximum range of the designs reported so far. Nearly 100% improvement is observed in the sensitivity of the two-axis accelerometer as compared with an existing design that occupied the same area. Multiple prototypes of XY positioners were fabricated on polypropylene sheets using CNC machining; and on spring steel and aluminium using wire-cut electro discharge machining. Mask layouts for two-layer two-axis accelerometers are designed for micro-fabrication using reactive ion etching and wafer bonding.

87	Les productions d’huile et de vin dans les Alpes-Maritimes antiques / The productions of olive oil and wine in the ancient Alpes-Maritimes Clément, Paul 13 June 2016 (has links) L'étude a consisté à effectuer l'inventaire, dans l'actuel département des Alpes-Maritimes, des sites archéologiques ayant produit de l'huile d'olive et du vin et à établir le catalogue des mobiliers dédiés à ces productions. A fin 2015, 70 sites ont été répertoriés, comportant 250 éléments de mobiliers appartenant principalement à des installations de pressage, ainsi qu'à quelques moulins à broyer les olives de type mola olearia, qui ont fait chacun l'objet d'une fiche. Les installations de pressage ont connu leur plus fort développement au début de l'Empire romain. Alors que la plupart des installations vinicoles cessent de produire au IIe siècle ap. J.-C. ou au début du IIIe siècle, , la production d'huile d'olive, après un ralentissement au IIIe s., est relancée au Bas-Empire, jusqu'à l'Antiquité tardive. Cette étude donne un premier aperçu global des aspects technologiques et économiques des productions d'huile d'olive et de vin dans la région. / This work presents a catalogue of archeological sites and equipments related to the production of olive oil and wine in the present Département des Alpes-Maritimes. By the end of 2015, 70 sites had been indexed, including 250 archeological items , mostly concerning pressing facilities and some crushing mills (molae oleariae); all of which have been recorded on individual data sheets. The major development of the rural press settlements was found at the beginning of the Roman Empire. While most wineries stopped producing during the 2nd century A.C. or in the early 3rd century, the production of olive oil, after a slowing down in the 3rd century, experienced a revival during the Low Empire and until the Late Antiquity. The analysis has given a global first insight into the economic and technological dimensions of olive oil and wine production in the region Huile d'olive Vin Installation de pressage gallo-Romaines Mola olearia Contrepoids Pressoir à levier Pressoir à vis Olive oïl Wine Gallic-Roman press installations Olivecrushing mills Mola olearia Weight stones Lever press Screw press
