Controle Robusto Aplicado a Conversor Buck-Boost em Sistemas Fotovoltaicos

The need to implement a software architecture that promotes the development of a SCADA supervisory system for monitoring industrial processes simulated with the flexibility of adding intelligent modules and devices such as CLP, according to the specifications of the problem, it was the motivation for this work. In the present study, we developed an intelligent supervisory system on a simulation of a distillation column modeled with Unisim. Furthermore, OLE Automation was used as communication between the supervisory and simulation software, which, with the use of the database, promoted an architecture both scalable and easy to maintain. Moreover, intelligent modules have been developed for preprocessing, data characteristics extraction, and variables inference. These modules were fundamentally based on the Encog software

Minas e a aclamação de D. João VI no limiar da formação do Estado-Nação brasileiro: memórias, conflitos e sedições

Dans cet article on examinera les cérémonies d'acclamation du roi D. João VI qui ont eu lieu à Tejuco en 1818. Le décodage de la riche variété d'images esthétiques présente dans ces célébrations peut être une stratégie privilégiée pour comprendre la création, à ce moment-là, des mythes qui donneraient soutien et orientation au projet d'affirmation du prestige politique du roi et à la consolidation de sa domination sur la région et sur tout le territoire brésilien. on analysera en particulier le conflit de mémoires entre la signification symbolique de la célébration et la révolte du peuple de Minas contre l'exploitation coloniale portugaise qui avait éclaté dans la région environ trois décennies avant.

João Cabral de Melo Neto: a estética do avesso

La pieza-poema Morte e Vida severina Auto de natal pernambucano, de João Cabral de Melo Neto, publicada en 1956, es el principal objeto de este estudio, interaccionando con las obras O Cão sem plumas y O rio por la similitud temática entre ellas: el estudio sobre esas obras busca una lectura desvinculada del posicionamiento constructivista y metalingüístico que por tradición configura la obra cabralina, no por negar a la crítica literaria que da respaldo científico, pero con la pretensión de lanzar una nueva mirada dirigida para el concepto de barroco, materia ésta que implica la creación poética a partir de la segunda mitad del siglo XX. Por lo tanto, este trabajo presenta una propuesta de análisis de la poesía de João Cabral a partir del contexto neobarroco. Considerando, sobre todo, los aspectos similares a la temática del barroco, el enfoque recae sobre la influencia de la literatura ibérica por que pasa el poeta João Cabral, así como la temática sobre el conflicto existencial explorado en el texto Morte e Vida severina, y aún, los extractos de lenguaje con significación múltiple que presentan signos metonímicos y metafóricos.

A doença de criar passarinhos: a lírica humanizadora de João Cabral de Melo Neto

João Cabral de Melo Neto n a jamais aimé les vers sentimentaux et prolixes venus de la tradition romantique. C est pour ça que son uvre a un discours objectif, rigoureusement elaboré e elle comporte certaines influences concretistes ça explique pourquoi l auteur est connu comme l ingénieur de la langage. En verité, le poète même dissait qu il était un homme froid et rationnel. La critique a assidument analysé la matière logique et le rigeuer formel de l uvre de Cabral de Melo. Pourtant, dans ce travail nous analysons les poèmes dont le sentiments humaines sont la mtière principal de l élaboration de l experiènce esthétique. La poèsie de João Cabral n est pas simple verbalisme formel, ni un uvre sens vie, car les objects concrètes et la langage objectif n empêchent pas qui le sujet décrit avec émotion les scènes presents dans les poèmes. Nous travaillons avec la hypothèse de que le poète a une attitude trop humaine quand il parle de l experience culturel et de l experience de la vie dans le Nord-est brésilien. Les unités témathiques de ce travail, pourtant, montrent la représentation du Nord-est dans la poèsie de João Cabral et examinent aussi le sentiment qu il sent par la memoire culturel de sa région. Parmi les aspects qui composent sa lyrique humaine nous citons la personification constant de les paysages du Nord-est le poète ne veux pas faire une décrition tophographique de la région parce que les places ont un valeuer sentimentel pour lui; au moyen d un discours erotique, Cabral represente les desirs et les intints humaines de sa terre; ensuite, il semble que le poète est enchanté et enveloppé avec certains elemets culturels de sa région, come l hamac, la littérature oral et la musique régional; la preoccupation avec la population explorée et la denonciation de la condition miserable dans le Nord-est brésilien confirment aussi la humanité présent dans son uvre; finalment, la récordation de l enfance et la nostalgie du temps passé sont, pour le poète, un possibilité qui peut aider dans la formation humaine de la population

O espelho dos hieróglifos: da ruína das letras egípcias à sua reinvenção quimérica entre os séc. XV e XVII

Das margens do espelho: um estudo dos reflexos da morte em primeiras estórias, de João Guimarães Rosa

This paper is divided into three chapters, which are structured as follows: in the first chapter, we examine the figure of death and its characteristics in the context of the work of Guimarães Rosa, within a specific type, determining how this figure comes through " imposition "," no "," memory "and" ritual. " We intend to cover all the possibilities that this aspect denotes. In the second chapter, we found the incidence of the mirror as an analysis of our study, characterizing it as a stylistic condition can become a reading key, necessary for interpretation of the book "First Stories". The characterization of the mirror as an element of analysis has a theoretical foundation which stretches out along other literary works that are based on the same object. By setting the points where these works approach the theories of speculation, we want to justify their use from our perspective

O auto da morte e da vida : a escrita barroca de João Cabral de Melo Neto

This dissertation, entitled O Auto da Morte e da Vida: A escrita barroca de João Cabral de Melo Neto, has the aim of analising, interpreting, in a baroque perspective, Cabral s writing in the poem/play Morte e vida severina Auto de Natal Pernambucano, taking as basis the theories of Eugênio D´Ors, Severo Sarduy, Omar Calabrase, Lezama Lima, Afonso Ávila, Affonso Romano de Sant´Anna and others cited in the body of this work. During the analisys we feature confluences, relations, similarities, identification between the Baroque of the counter reformation and the modern Baroque or Neobaroque. We seek to comprehend the baroque which is new in the XX century and Cabral s poetry as an element of the contemporaneity, by updating the concept of the Baroque in the 1600s, when it is detected in its purest characteristic in human relation (the life of the Northwestern brazilian) through an intangible reality (the death). The Baroque as a cultural summary of a period of instability and transformation, with the power of dismantling an already established poetry. The fight between words and things, language and reality

Resistência e performance na arte de João Cota

Researching about the art of tell and the tales told by João Cota is somehow revisiting the oral tradition and social practice in the story-telling art. It takes into consideration the resistance this art still exerts, mainly by using the performance of oral transmission and receptiveness to tales. The study of this practice contributes to the vivacious and dynamcis permanence of this authentic and traditional storyteller of his repertory and of his form to tellin our culture. Story-telling is part of the humankind living heritage communicated by means of popular wisdom. Despite the risk of vanishing into thin air, along with their narrators, the tales still manage to resist the contemporary mass culture model. How long further will stories like the ones narrated by João Cota be able to resist to strong and stronger structures dictated by writing and other communication means? João Cota s practice in story-telling will be studied not only as a proposal to identify the presence of this practice and the oral cultural resistance but also, through the performance prospective, to identify the oral transmission and receptiveness to the tales that are part of this storyteller s repertoire. In other words: what he tells, how he tells it, and why he tells it. The advent of new technologies such as internet, through which people can easily communicate with others in different parts of the world, and the greater and greater expansion in the writing skill concept interfere the maintenance of the oral tradition elements present in João Cota s narratives and inserted in the Brazilian culture. This has become more visible in the latest decades although we still notice the living tradition and permanence of the story-telling practice in several parts of the country through their wise storytellers. Our research target will require - in each of its study stages reference to works by several theoreticians namely Paul Zumthor, Mikhail Bakhtin, Câmara Cascudo, theoreticians from the receptiveness aesthetic, from the written culture history, from oral cultures and reading practices, from tradition and the Brazilian Culture of oral story-telling. In order to get to know and draw a profile of this storyteller, we ve chosen to use the comprehensive interview method by French Sociologist Jean Claude Kaufmann. The originality in the method consists of the qualitative data put together in situ , concentrated on the storyteller s narratives/speeches recorded on tape, which will be the focal point of this study. Our analysis method is based on tireless sessions of listening to interviews out of which we gathered information related to the storyteller, his practice in telling the tales, and his repertoire

Representações discursivas no discurso político. Não me fiz sigla e legenda por acaso : o discurso de renúncia do senador Antonio Carlos Magalhães (30/05/2001)

O objetivo deste trabalho é investigar como as representações discursivas do locutor e dos alocutários são construídas no discurso de renúncia ao mandato de senador, proferido por Antonio Carlos Magalhães (ACM), na 62ª sessão deliberativa ordinária, em 30/5/2001. A perspectiva teórica que adotamos situa-se no campo da Linguística do Texto, com foco na abordagem da Análise Textual dos Discursos ATD (Adam, 2011). A noção de representação discursiva apresentada pela ATD constitui um dos aspectos da dimensão semântica do texto e baseia-se parcialmente nos trabalhos de Grize sobre a esquematização (1990, 1996). Complementamos as categorias de análise com contribuições que nos permitem detalhar a expressão linguística, textual, e discursiva das representações discursivas (Neves, 2006; Castilho 2010; Rodrigues, Passeggi, Silva Neto, 2010; Rodrigues et al. 2012; Passeggi, 2012). O enfoque metodológico é qualitativo, descritivo e interpretativista (Minayo, 1994; Trivinõs; 1987; Gil, 2002). Os procedimentos de análise utilizam as categorias semânticas de referenciação, predicação, modificação (de referentes e predicações), localização espacial e temporal, conexão e comparação. A representação discursiva do locutor (ACM) é constituída pelo conjunto de representações mais específicas, expressas nas referenciações e nas suas modificações: vítima; político; sigla; baiano, nordestino; presidente do senado; senador confiante; condenado. ACM, como protagonista, assume sempre a sua voz no discurso, manifesta seus pontos de vista e posiciona-se como sujeito ativo, consciente da importância do seu papel político e social, que o torna alvo e vítima das ações dos adversários. Complementando essa referenciação, as predicações e suas modificações se expressam através de verbos de ação, em especial, verbos na 1ª pessoa do singular que marcam o tempo presente, real e conclusivo de ações que constroem um cenário positivo para si mesmo. A localização temporal e espacial, indica as ações realizadas pelos participantes nas diversas etapas temporais selecionadas pelo texto, articuladas a três espaços principais: o Senado Federal, o Brasil e, naturalmente, a Bahia. Por sua vez, conectores adversativos (sobretudo, mas ), explicativos e condicionais acompanham e estruturam o ritmo argumentativo do discurso de renúncia de ACM

Vaga-lume na treva: a poesia de João Lins Caldas

This thesis analyses the poetry of João Lins Caldas (1888-1967), in Brazilian literature context, aiming at describing and understanding the main features of his poetry. Thus, this research presents a corpus to be worked on: the poems in Poeira do céu e outros poemas (2009). Our study is characterized by a biographical, historiographical and critical tendency, by trying to organize the manuscripts of the author and biographical aspects while analyzing his poems. It is showed the relation between Brazilian poetry written by some authors, since the parnasianism and symbolism period until the twentieth century. On the one hand, our analysis is based on the ideas and criticism by Antonio Candido (2006; 2002; 1985), discussing the process of formation of Brazilian literature and the procedure to analyse poetry. It is also based on the concept of poetry and resistance, developed by Alfredo Bosi (2000; 2002), and the notion of Brazilian matter, identified by Roberto Schwarz (1987, 1997, 1999). On the other hand, this work focuses on melancholy under the theoretical ideas of authors such as Aristotle (1998), Walter Benjamin (1984), Jaime Ginzburg (1997) and Moacyr Scliar (2003). This focus on melancholy contributes to a better understanding of one of the main themes found in the poems analysed. By studying the poetry of João Lins Caldas, it was perceived the relevance of melancholy and resistance in his verses. This can be seen in his dissonant language, characterized by the broken syntax in his verses, as well as contradictory images and complex meanings in his poetry. This causes the effect of unfamiliarity on the reader. His poetry is the result of a style that finds its place in the best moment of modern Brazilian poetry and reveals its singularity through the inverted syntax with powerful themes such as love, death, pain, delusion, loss, memory, nature and God. All of them are aspects of Brazilian historicity. Finally, the work of João Lins Caldas is part of a multifaceted poetry

O sertanejo e o sevilhano nos poemas de João Cabral de Melo Neto: o lusco-fusco barroco

The aim of this research is, starting from a Baroque reading, unfold the understanding of the poems by João Cabral de Melo Neto in the axis Pernambuco-Spain. From this perspective, the reading of poet s Obra Completa allows the appearance of two persons, one from Seville and other from the Brazilian countryside, whom curiously pulsate and reveal themselves from their homelands, Brazilian northeastern dry lands and Seville, to a labyrinthy meeting establishing a close and exciting relationship of cities apart but which mark a contiguous dialogue between both cultures. The theorical effort of this investigation permeates, approaches and contrasts the directions of, among others, Severo Sarduy (1999), Gilles Deleuze (2012) and Eugenio D Ors (unknown). Not traveling an anthropological bias, this study observes the Spanish space and the Brazilian northeastern dry lands space, joining the regional to the universal and analyzes the baroque game in the (re) construction of the both men s cultures. These elements fuse, approach and move away, causing a game of allusions to Pernambuco and Spain that show itself through a similar cultural bias and different at the same time. From this apprehension it is possible to understand the synthesis of the Brazilian arid northeast-Seville men as a update of seventeenth century Baroque coming from indexes that are shown over the particular written by João Cabral de Melo Neto, in the Iberian Baroque scenario and in the American one s

Representações discursivas de Ficar e Namorar em textos de vestibulandos e pré-vestibulandos

This doctoral thesis investigate the way vestibulandos and pré-vestibulandos construct their discursive representations of Ficar and Namorar in their textual production. At the same time, aims to discuss its implications for the ATD and for the teaching and learning of textual production in the context of Portuguese Language classes. Its theoretical framework is inspired mainly by three sources: textual linguistics, the textual analysis of discourses (ADAM, 2008), as well as by frames semantics (FILLMORE, 2006; FELTES, 2007). The methodology is based on a combination of qualitative and quantitative approaches (VIANNA et al., 2008). The data is composed of 168 empirical texts written by the vestibulandos of PSV/2005 da UFRN, Natal, RN, and by secondary school students who attended Escola Estadual Juscelino Kubitschek (EEJK), Assú, in the 2008 school year. The results indicate different categories of discursive representations of Ficar and Namorar , such as designation of referents, prediction, aspectualization, spatial-temporal circunstances , and metaphor, which reveal the influence of factors such as: the encyclopedic knowledge, the culture, as well as the cognitive components related to textual production. These results point out to the necessity of a teaching practice which enables the interaction among students, the discussion of current themes, as well as the student involvement with different textual genres, mainly the work with textual production in the classroom, so that it enables the students do acquire the textual production strategies. Thus, the overall goal is the (re)construction of their discursive representations, so that they can cope with new contexts of communicative interaction.

Inês de Castro no romance contemporâneo português

Ines de Castro is a theme in literature from the fourteenth century. The historical fact of his death, in 1355, became a landmark in the history of Portugal and, since then, several literary texts from various genres, have dealt with this theme, this made the couple Pedro and Ines a myth of love passion, of love beyond the barriers of death, like Tristan and Isolde, Romeo and Juliet, Abelard and Heloise. The literary myth - or any picture that mythologize literature - is always prepared before culturally and works in the same way that so many others, this is, as an element of cultural identity, either collectively or individually, making it also a feature poetic. Thereby, is an archetype confirmed through time and eventually reveals a series of webs of the human psyche.

Authored by Agustina Bessa-Luís, João Aguiar, António Cândido Franco, Seomara da Veiga Ferreira and Luis Rosa, the six novels studied show the circularity cultural of inesian myth showing this new character of the new person Ines in the contemporany historical novel

Referências culturais e heterogeneidade discursiva :Uma proposta para o ensino-aprendizagem de língua inglesa

The purpose of this research is to approach the English literary text from the point of view of the culture and the heterogeneity of discourse in its role as a source of elements that facilitate the teaching/learning process of English as a foreign language. Several instances of discourse heterogeneity are analyzed through cultural references in the original texts of the following English novels: Jane Eyre, by Charlotte Brontë (1816-1855), published in 1847; The Mill on the Floss, by George Eliot (1819-1890), published in 1860 and Great Expectations, by Charles Dickens (1812-1870), published between 1860 and 1861. Theoretical support was sought in Kramsch, Bakhtin, Maingueneau, Authier-Revuz, Widdowson and Larsen-Freeman. Activities in English are proposed in the end whereby it can be seen that the questions at issue can be used extensively in the classroom.
