O texto adaptado à máquina: estratégias de controle autoral para implementação da tradução automática

Machine translation systems have been increasingly used for translation of large volumes of specialized texts. The efficiency of these systems depends directly on the implementation of strategies for controlling lexical use of source texts as a way to guarantee machine performance and, ultimately, human revision and post-edition work. This paper presents a brief history of application of machine translation, introduces the concept of lexicon and ambiguity and focuses on some of the lexical control strategies presently used, discussing their possible implications for the production and reading of specialized texts.

Modelagem computacional das túnicas cardíacas para processamento e controle de qualidade

This paper considers a study of the anatomical features of the cardiac system and a three-dimensional model of the different tunics that comprise the heart wall, for processing and quality control of radiological images. The structures are built by the layer overlapping method, where a layer can be understood as a slice of the three-dimensional object. The pericardium, myocardium and endocardium were represented with three-dimensional cylinders and hexagons. The spatial arrangement of the cardiac system is determined by an background image of a real model, which values are defined according to the shape of the region and on the anatomical patients characteristics. The results are significant, considering the anatomical structures details, as well as the representation of the thicknesses of the regions of the heart wall. The validation of the anatomical model was accomplished through comparisons with dimensions obtained from a real model and allows verifying that the model is appropriate. The degree of representation will allow the verification of the influence of radiological parameters, morphometric peculiarities and stage of the diseases on the quality of the images, as well as on the performance of the Computer-Aided Diagnosis (CAD).

Estudo sobre o funcionamento de sistema de controle de tração em veículos automotores

This study explores the subject of traction control systems through bibliografy review on the spot of Mechanical Engineering. This paper has the objetivo of high light the main components and tecnology involved since MaxTrac system in 1971. It describes systems controled by throttle valve and breaks. Additionally, it i also presented basic knowlodged regarding electronic control unit and wheel sensors

Controle de Acesso utilizando Arduino, banco de dados MySQL e LabVIEW

The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker

Efeitos de diferentes sistemas de clareamento dental sobre a rugosidade e morfologia superficial do esmalte e de uma resina composta restauradora

The aim of this study was to evaluate and compare the roughness and superficial morphology of enamel and a composite restorative resin after different bleaching techniques application. Material and Methods: Bovine incisors were selected and standardized cavities were prepared on the buccal surface, which were restored with composite resin. The teeth were distributed according to the following treatments: G1- bleaching with 10% carbamide peroxide (CP); G2 - bleaching with 38% hydrogen peroxide (HP); and G3 - bleaching with 38% of HP associated to light irradiation. For G1, the bleaching gel was applied for 8 hours daily during 21 days. For G2 and G3, 3 sessions were performed, consisting of 3 applications of 15 minutes each, with 7 days of intervals between the sessions. For G3, the LED (470nm) light was used to activate the bleaching agent for 6 minutes. The surface of enamel and composite resin were evaluated before and after the bleaching procedures using a roughness tester and an atomic force microscope. Results: The results showed significant differences in surface roughness of enamel after bleaching only for G1 (Wilcoxon, p<0.05). For composite resin, neither group showed a statistical difference compared to control (Mann-Whitney, p>0.05). Conclusion: It was concluded that the increase in the roughness of enamel occurred only after bleaching therapy using a gel with 10% of CP. The bleaching procedures evaluated in this investigation did not increase the roughness or cause changes in the superficial morphology of the composite resin.

Correspondência de cor de diferentes marcas e sistemas de resina c omposta em relação à escala vita classical

The objective of this study was to compare different resins and determine their matching color with Vita shade, also investigating the possibility of substitution among them and the correlation between the visual and spectrophotometry methods of color selection. The composite resin Tetric N-Ceram® shade A1 was used as light-control and color A4 as dark-control. For each material were prepared five 10 x 2 mm disks. Analyses were performed in a metamerism box by volunteers who ordered the specimens from the lightest to the darkest. The spectrophotometry was carried out using the spectrophotometer Vita Easyshade®. ∆E values were subjected to analysis of variance with 5% significance level. The Fisher exact test showed that there was no color match among the materials and the reference Vita shade. The possibility of substitution among the composites could not be established. The two methods are able to correctly differentiate the control resin A4 as distinct from the other resins shade A2.

Estudos em políticas públicas: cidadania, desenvolvimento e controle social

Os 13 artigos reunidos neste livro foram primeiramente apresentados em encontro internacional sobre participação, democracia e políticas públicas na América Latina, realizado em 2013 na Faculdade de Ciências e Letras da Unesp. Para os organizadores da obra discutir o tema, principalmente no que concerne à transparência dos sistemas de gestão, é extrema importância para apontar direções para uma renovação política, articulações sociais e desenvolvimento socioterritorial. Eles explicam que a análise de marcos legais, fragilidades institucionais e prática autoritárias permitem enxergar o seu contrário e, com isso, aprimorar a prática de políticas públicas voltadas ao desenvolvimento de um país sustentado na democracia e na cidadania ativa. O livro é divido em quatro eixos temáticos. O inicial apresenta artigos que analisam a cidadania relacionada à saúde, gênero, prevenção ao abuso sexual e juventude. Abarca temas como o Sistema Único de Saúde, os movimentos e grupos feministas e abuso sexual. O seguinte destaca temas ligados à educação, também relacionados à cidadania, como o financiamento da educação e a educação em presídios paulistas. Desenvolvimento e combate às desigualdades sociais norteiam os estudos da terceira parte. São três artigos que tratam da complexidade da produção de políticas baseadas no diálogo entre pares institucionais, como representantes de governos e sociedade civil. O capítulo final é dedicado ao tema controle social e aperfeiçoamento da democracia. Os artigos abordam a questão do monitoramento das políticas e investimentos públicos por parte da sociedade civil.
