This investigation aims at describing, analyzing and interpreting the Commitment in Initial Petitions, which is a genre circumscribed in the judicial domain. For this purpose, we have chosen sections, facts as found and relevant law , sections of the petition, with the understanding that, in this way, respectively, the narration of events, which gives margin to the propositioning to the judicial action, and the exposition of the law that upholds the author s intention. We base our discussion on the field of Linguistics, more precisely, Textual Discourse Analysis (TDA), whose theoretical basis is derived from Textual Linguistics (TL) and Enunciative Linguistics. We foreground, particularly, the way in which the author of texts, objects of analysis, use discursive strategies that evidence ER. The relevance of this study, then, is in the formation of a critique of the judicial text, as it conceives of a dialogical approach to the point of view, raising not only questions about the way in which a linguistic instance conceives an object of discourse, but also considering questions of language inherent to technical writing and, in this aspect, contributing to the work of those operating in Law about the many ways ER is formed in the body of a petition. We selected two categories to analyze that, according to Adam (2011), characterize the degree of ER in the textual material of the propositional enunciations: the different types of representation of speech and the indications of profile of mediators. In this sense, with this task as an objective, we base our study regarding point of view on Rabatel (2003, 2009a, 2010) with relation to the enunciative approach, including the study of PDV in polyphonic and dialogical theoretical framework to study the ER from different types of speech representations that conceive forms of transmission of discourse and the role of the enunciating subject, mainly the responsibility and the prerogative by the propositional contents. In the same way, intending to study the indications of the mediator profiles, we observed the postulations of Guentchéva (1994, 1996), which develop the notion of mediative grammatical categories, of which permit the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. The methodology we adopted was based on qualitative research, of an interpretive and introspective nature, in light of the fact that his study focuses on processes and strategies underlying language use. The corpus of the research is comprised of Initial Petitions, which gave rise to actions originating in the Civil Court of Currais Novos County RN. The data analysis shows that an object of discourse is always perspective oriented and presents the point of view of one or more enunciators. Consequently, the producer of a text, using the PDV of other enunciators, influences and establishes the argumentative orientation of the text. In the same way, it evidences the relevance of the use of mediated constructions in the judicial text, as they function as strategies attenuated to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law. Moreover, it reveals the documental and international importance of this practice, at the same time that it exposes the compositional and normative difficulties with regard to legal and linguistic aspects

This paper presents a new approach for damage detection in structural health monitoring systems exploiting the coherence function between the signals from PZT (Lead Zirconate Titanate) transducers bonded to a host structure. The physical configuration of this new approach is similar to the configuration used in Lamb wave based methods, but the analysis and operation are different. A PZT excited by a signal with a wide frequency range acts as an actuator and others PZTs are used as sensors to receive the signal. The coherences between the signals from the PZT sensors are obtained and the standard deviation for each coherence function is computed. It is demonstrated through experimental results that the standard deviation of the coherence between the signals from the PZTs in healthy and damaged conditions is a very sensitive metric index to detect damage. Tests were carried out on an aluminum plate and the results show that the proposed methodology could be an excellent approach for structural health monitoring (SHM) applications.

This work proposes a method for dioptric power mapping of progressive lenses through dual wavelength, low-coherence digital speckle pattern interferometry. Lens characterization finds several applications and is extremely useful in the fields of ophthalmology and astronomy, among others. The optical setup employs two red diode lasers which are conveniently aligned and tuned in order to generate a synthetic wavelength. The resulting speckle image formed onto a diffusive glass plate positioned behind the test lens appears covered of contour interference fringes describing the deformation on the light wavefront due to the analyzed lens. By employing phase stepping and phase unwrapping methods the wavefront phase was retrieved and then expressed in terms of a Zernike series. From this series, expressions for the dioptric power and astigmatic power were derived as a function of the x- and y-coordinates of the lens aperture. One spherical and two progressive lenses were measured. The experimental results presented a good agreement with those obtained through a commercial lensometer, showing the potentialities of the method. © 2013 Elsevier Ltd.

Com base em estudos que tomam como eixo central a alfabetização e o letramento, esta dissertação compreende uma investigação acerca da influência dos métodos de alfabetização, mais especificamente do método silábico e da proposta de alfabetização com base lingüística (ABL), na produção textual escrita de alunos de 1 série do Ensino Fundamental, alfabetizados ou pelo método silábico ou pela proposta ABL. Para tanto, este estudo partiu da hipótese de que a relação oralidade/escrita estabelecida pelo aluno em suas produções e a utilização de um número restrito de elementos coesivos que estabelecem as relações de sentido entre os enunciados que compõem o texto é, em parte, responsabilidade dos métodos e/ou propostas de alfabetização adotados. O diálogo estabelecido com autores que dão visibilidade à prática de alfabetizar letrando; os estudos sobre letramento, alfabetização, psicogênese da língua escrita e a produção de textos escolares ajudaram na condução desse trabalho, que além da pesquisa bibliográfica se valeu da pesquisa de campo realizada nas escolas N.S.A e L.C pertencentes à Rede Municipal de Ensino de Ananindeua e à Rede Privada de Ensino de Belém, respectivamente. Durante esta pesquisa, foram observados o desenvolvimento do trabalho de quatro professoras com turmas de alfabetização e da produção textual de doze alunos de duas turmas de 1 série da escola N.S.A; também foram aplicados dois questionários a sete professoras de turmas de alfabetização e 1 série das duas escolas citadas. A referida pesquisa tornou possível perceber que a alfabetização já começa a ser vista como um processo que visa não só ao domínio da tecnologia da leitura e da escrita, mas também aos usos sociais dessa tecnologia; mostra também que os alunos alfabetizados pela proposta ABL usam um maior número de elementos coesivos em suas produções que os alunos alfabetizados pelo método silábico e que a relação entre a fala e a escrita estabelecida na escrita de palavras é muito mais forte nas produções textuais escritas dos alunos alfabetizados pela ABL.
