Las ermitas del Desierto de Las Palmas. Historia y Actualidad de una idea

Husillos Tamarit, Ignacio 21 March 2016 (has links)
[EN] This work tries to clarify the data and documents that deal with the Desert of The Palms and its hermitages. The initial approach is based on the merger of the historic, the architectural and the spiritual, to carry the reader through a common thread of what was, symbolically, and how it materialized in architecture and its environment. It should be noted that the work does not try to make a constructive and graphic description of what were the hermitages, but is a mere description of the construction, to understand the symbolism of space itself. This is part of the existing literature, documentary research and, above all, called «anonymous manuscript 1778», which is a description of the Desert of The Palms. Significant data that have been erroneously documented by other authors, as well as deepen the analysis of all the elements of the set of the desert will clarify. The contribution of this thesis consists, first, in the differentiation of two times historic place, one in the old framework (17th to 19th centuries) and the other in the new framework (19th to 21th centuries). This will merge the texts of two frames, for a bigger and better understanding of the place; and, like nexus, spirituality. This line refers the Desert of The Palms in key of paradise, justifying it with other Carmelite Deserts around the world and appearing so characteristic symbolism as the Carmelite Laura. Second are the different types of the hermitages and other related buildings to them in the Desert of The Palms, distinguishing between the set as the union of the parties and individual parties as essential elements of the set. Thus focuses attention on two aspects: the first is the documentary, based principally in the mentioned anonymous manuscript, which suggest his authorship (based on archival research and transcription of unpublished documents); and the second aspect is the bibliographic, extracting the texts presenting the whole of the hermitages. Reading through a heritage catalogue makes it easier to understand the materialization of the hermitages and other constructions in an individualized manner. Part of the old text and part of the current description is summarized in the tabs. Tops is working with an unpublished analysis of the spiritual values of the hermitage, creating a fruitful dialogue between architecture and spirituality. / [ES] El presente trabajo trata de esclarecer los datos y documentos que versan sobre el Desierto de Las Palmas y sus Ermitas. El planteamiento inicial se basa en la fusión de lo histórico, lo arquitectónico y lo espiritual, para llevar al lector mediante un hilo conductor de lo que fue, simbólicamente, y como se materializó en la arquitectura y su entorno. Cabe destacar que el trabajo no intenta hacer una descripción gráfica y constructiva de lo que fueron las ermitas, sino que es una mera descripción de la construcción, para entender la simbología del espacio en sí. Para ello se parte de la bibliografía existente, la investigación documental y, sobre todo, el llamado «manuscrito anónimo de 1778», que es una descripción del Desierto de Las Palmas. Se esclarecen datos significativos que han sido documentados erróneamente por otros autores, además de profundizar en el análisis de todos los elementos del conjunto del Desierto. La aportación de esta tesis consiste, en primer lugar, en la diferenciación de dos tiempos históricos del Lugar, uno en el marco antiguo (siglos XVII al XIX) y el otro en el marco nuevo (siglos XIX al XXI). De este modo se funden los textos de los dos marcos, para una mayor y mejor comprensión del lugar; y, como nexo de unión, la espiritualidad. En esta línea se habla del Desierto de Las Palmas en clave de Paraíso, justificándolo con otros Desiertos Carmelitanos a nivel mundial y apareciendo simbolismos tan característicos como la Laura carmelitana. En segundo lugar, se tratan las distintas tipologías de las Ermitas y otras edificaciones vinculadas a ellas en el Desierto de Las Palmas, distinguiendo entre el conjunto como la unión de las partes y las partes individuales como elementos esenciales del conjunto. De este modo se focaliza la atención en dos vertientes: la primera es la vertiente documental, basándonos principalmente en el mencionado manuscrito anónimo, del que proponemos su autoría (basándonos en la investigación archivística y la transcripción de documentos inéditos); y la segunda vertiente es la bibliográfica, extrayendo los textos que presentan al conjunto de las Ermitas. Para entender de manera individualizada la materialización de las Ermitas y otras construcciones, se facilita su lectura mediante un catálogo de fichas patrimoniales. En las fichas se resume parte del texto antiguo y parte de la descripción actual. Se remata el trabajo con un análisis inédito de los valores espirituales de la Ermita, creando un fructífero diálogo entre la arquitectura y la espiritualidad. / [CAT] El present treball tracta d'esclarir les dades i documents que versen sobre el Desert de Les Palmes i les seues Ermites. El plantejament inicial es basa en la fusió d'allò històric, allò arquitectònic i allò espiritual, per a portar al lector mitjançant un fil conductor d'allò que va ser, simbòlicament, i com es va materialitzar a l'arquitectura i al seu entorn. Cal destacar que el treball no intenta fer una descripció gràfica i constructiva del que van ser les ermites, sinó que és una mera descripció de la construcció, per a entendre la simbologia de l'espai en si. Per a això, es parteix de la bibliografia existent, de la investigació documental i, sobre tot, de l'anomenat «manuscrit anònim de 1778», una descripció del Desert de Les Palmes. S'esclareixen dades significatives que han sigut documentades erròniament per altres autors, a més d'aprofundir en l'anàlisi de tots els elements del conjunt del Desert. L'aportació d'esta tesi consisteix, en primer lloc, en la diferenciació de dos temps històrics del Lloc, un en el marc antic (segles XVII al XIX) i l'altre en el marc nou (segles XIX al XXI). Així es fonen els textos de tots dos marcs, per a una major i millor comprensió del lloc; i com a nexe d'unió: l'espiritualitat. En esta línia es parla del Desert de Les Palmes en clau de Paradís, justificant-ho amb altres Deserts Carmelitans a nivell mundial i apareixent simbolismes tan característics com la Laura carmelitana. En segon lloc. es tracten les distintes tipologies de les Ermites i altres edificacions vinculades a elles en el Desert de Les Palmes, distingint entre el conjunt com la unió de les parts i les parts individuals com a elements essencials del conjunt. D'aquesta manera es focalitza l'atenció en dos vessants: el primer és el vessant documental, basant-nos principalment en el mencionat manuscrit anònim, del que proposem la seua autoria (basant-nos en la investigació arxivística i la transcripció de documents inèdits); i el segon vessant és el bibliogràfic, escollint els textos que parlen del conjunt de les Ermites. Per a entendre de manera individualitzada la materialització de les Ermites i altres construccions, es facilita la seua lectura mitjançant un catàleg de fitxes patrimonials. En eixes fitxes es resumeix part del text antic i part de la descripció actual. Es remata el treball amb una anàlisi inèdita dels valors espirituals de l'Ermita, creant un fructífer diàleg entre l'arquitectura i l'espiritualitat. / Husillos Tamarit, I. (2016).

Erri De Luca e la Bibbia : un autore formatosi sulle sacre scritture / Erri De Luca and the Bible : an author shaped by the Sacred Scripture

Porczyk, Anna Malgorzata 12 May 2016 (has links)
Cette étude vise à fournir une vision de la poétique de l'auteur contemporain Erri De Luca, à travers l'étude des éléments et des motifs empruntés aux Écritures particulièrement prégnants dans son œuvre. De tels éléments, renvoyant aux sources bibliques, fournissent une clef pour la lecture et pour l'interprétation de l'œuvre deluchienne dans sa complexité. L'insertion de l'imagery biblico-littéraire, chargée d'éléments qui depuis des siècles sont ancrés dans l'imaginaire collectif confère une unité à l'écriture de cet auteur, en dépit de sa variété. Le terme imagery est utilisé pour exprimer un ensemble d'images auxquelles appartiennent les symboles, les métaphores, les comparaisons, les thèmes, les conventions, ainsi que les archétypes, appartenant aux Saintes Écritures. La poétique de De Luca est analysée ici au moyen de l'identification des images qui constituent les principaux éléments de la narration des auteurs de la Bible, comme de l'auteur napolitain.En prenant comme objectif l'étude de l’œuvre deluchienne du point de vue de l'imagery des Saintes Écritures, ce travail se divise en quatre parties. La première partie vise à fournir un cadre général des échos bibliques dans la littérature italienne contemporaine, en proposant une brève description des thèmes et motifs qui ont inspiré, et continuent d'inspirer, les romanciers et poètes italiens. En outre, dans cette partie nous traitons les principales tendances que l'on peut dégager dans les différents écrits littéraires d'inspiration biblique, en nous appuyant sur quelques exemples. Ainsi, il est possible de déterminer la place qu'occupe la poétique de De Luca dans le contexte de la littérature italienne du XXième siècle, où la présence de la Bible est considérable. L'auteur napolitain, bien que dépourvu de sentiments religieux, non seulement comprend les Saintes Écritures à travers leur sens métaphorique, mais en fait également la matrice conceptuelle de ses propres œuvres littéraires, en créant un univers biblico-littéraire cohérent et entièrement personnel.Dans le deuxième chapitre, nous parcourons brièvement la biographie de De Luca, et en particulier certains aspects de sa vie personnelle en référence à ses œuvres. De telles références, récurrentes dans l'écriture deluchienne, forment un des deux macrotextes où l'écrivain puise pour créer sa propre poétique, celui de la vie. Dans cette partie, nous évoquons les concepts et les mots-clés forgés par De Luca lui-même, à travers le prisme desquels il semble souhaiter être lu et interprété. Le premier de ces concepts est la nostalgie des racines, idée à laquelle se rattachent les réflexions sur l'autre possibilité, ainsi que sur l'extranéité au monde. Il découle de cette analyse une description du militantisme politique de l'auteur. Enfin, on abordera l'expression utilisée par l'auteur pour définir son rapport avec la religion, à savoir sa condition de non-croyant. Dans la troisième partie, nous décrivons l'évolution de l'intérêt de De Luca pour la littérature, la traduction et l'interprétation des Saintes Écritures. Nous commençons par évoquer sa passion pour la culture et pour l'histoire juive, indissociable de l'étude de la langue de l'Ancien Testament, cette dernière ayant été apprise en vue de lire le texte biblique dans sa forme originaire. Cela a ensuite mené l'auteur vers un approfondissement des pratiques cabalistiques qui, à leur tour, lui ont permis de se lancer dans l'exégèse biblique. Ensuite, nous passons à une brève description des traductions deluchienne de certains livres de la Bible dans lesquelles l'auteur tente de restituer le plus fidèlement possible la forme originaire, en utilisant la langue italienne comme un simple moyen de faire entrevoir l'original. C'est pour cette raison que les traductions sont abordées dans cette analyse comme étant des connecteurs, ainsi qu'un moyen pour arriver du texte d'origine vers l'écriture, plus dans le sens conceptuel que séquentiel. / The aim of the dissertation is to analyze the prose of the modern Italian writer Erri De Luca through the lens of biblical motifs and references, which bind his works together. Such references to biblical sources are the key to understanding and interpreting the author's writings, which, despite their multifaceted character, nonetheless remain grounded in biblical-literary imagery; one rich in references rooted in the human imagination since centuries past. The term imagery encompasses the entire set of biblical images including symbols, metaphors, comparisons, motifs, and archetypes. The analysis of De Luca's writings consists in foregrounding those images which constitute the fundamental elements of the narration both in the case of biblical authors, as in the case of the Neapolitan writer himself. The dissertation comprises four parts. Chapter One attempts to present the general framework of biblical references in modern Italian literature in the form of a short description of the themes and motifs taken up by Italian poets and prose writers alike. Furthermore, the chapter discusses and exemplifies the main tendencies in literary references to biblical imagery, which will then allow us to observe the ways in which De Luca's works partake in the larger body of 20th century Italian literature with visible biblical influences. Despite his declared lack of religious faith, the Neapolitan writer not only decodes the metaphorical sense of the Bible, but also adopts the Bible as the framework for his writings, thus creating a personal, unified, and unique biblical-literary universe. Chapter Two includes a short biographical note on the writer with a strong emphasis on those aspects of his life which are reflected in his writings. And because such references are numerous indeed, they comprise one of the two macrotexts that the writer refers to in his poetics, i.e. the life (vita) macrotext. This section also presents keywords introduced by De Luca himself. It can be assumed that the author wanted to point his readers and critics to a specific method of reading and interpreting his art. The first keyword of this kind refers to the concept of a longing for the return to the source, which is tied to reflections on the so-called other possibility (altra possibilità) and one's alienation from the exterior world. The later part of the chapter describes the author's political engagement and reflects on the meaning that De Luca ascribes to the word non-believer (non-credente), which the author uses to describe his personal approach to religion. Chapter Three describes the author's interest in reading, translating, and interpreting the Bible, starting with his interest for Jewish history and culture, the roots of which may be traced back to De Luca's study of the Hebrew language. The author undertook the study in order to be able to read biblical texts in their original language, which, in turn, has led him to acquaint himself with Cabalistic practices, enabling him to employ his own biblical exegesis. The chapter then provides an overview of De Luca's own translations of selected biblical texts, a distinguishing feature of which is the author's attempt to remain as faithful as possible to the original text. In this regard, De Luca treats the Italian language as a mere tool and does not consider the process of translation to be an end in and of itself. For this reason, the dissertation treats his translations as a “connector” of sorts, as well as a stepping stone in the journey from the source text to writing itself – more so in a conceptual sense than a temporal sense. The further part of the chapter will consist of an analysis of those of De Luca's works which could be described as “rewriting” biblical tales (riscritture), a process which is not only considered to be a distinct kind of translation, but even the next stage in the work of the translator.

The Study of Brand Strategy: A Case Study of Don Don Taro Balls / 品牌經營策略-以東東芋圓為例

DONG, ZHENG-SHENG, 東正勝 January 2017 (has links)
碩士 / 逢甲大學 / 經營管理碩士在職專班 / 105 / In recent years, many fancy, diversified and extreme popular deserts emerge in the desert market in Taiwan. Under the gradually manifold consumption demands, the increasing consumption needs also raise the customers’ growing requirements of deserts that drive desert merchants to launch more varieties and pay more attention to material selection and manual work in order to satisfy consumption desires. In the meantime, desert markets have grown up to replace the market shares of domestic bake market. Those situation cause an increasing development and growth of competitive strengths of desert market brands and a unceasing spending power raise of consumers in desert and enables tremendous development potentials of the consumer market. This research focuses on discussing over the internal and external operational analyses of Don-Don Taro Ball, proposing the personnel and matters involving in the problems. The desirability and importance of brand management strategies can be reached by Document Analysis Method, case study of sing-point desert merchants as well as in-depth interview. Moreover, from the differences between single-point store and chain brands in terms of operational strategies, we can learn that 1. The cooperation with farmers can rigorously control on the quality stability of raw materials. 2. The efficient labor management is conductive to salary structure to maximize. 3. The business mode based on directing sales and joint stock is beneficial for expanding franchise, completely reproducing the transmission of quality and philosophy. 4. Scale up the pattern, we not only sell deserts, but also sentiments,. Furthermore, we combine the visual effects and marketing strategies to convey brand spirits and attract consumers; based on the foregoing, the brand development strategies and structures of case study companies are created to break through the blind-spots of current operations.

Import Fire Evacuation safety Analysis of deserted Community Space Redevelopment:In Min Hwan New village Case / 導入防火避難安全解析之閒置社區空間再利用設計:以煥民新村區塊為例

Kuan-Yu Lin, 林冠妤 January 2017 (has links)
碩士 / 國立臺灣科技大學 / 建築系 / 105 / In recent years, the cultural assets preservation trend has been rise. Historical buildings redevelopment was being attention. Due to the historical building’s vulnerability, the recent fire safety standards of construction law can not be limit it. Also, the historical building can not obtain construction licenses and use. For this reason, the historical building may be lack of fire safety equipment and fire management system. We research basic prototype of military community deserted space. Then, we import Fire Dynamics Simulator for testing building escape evacuation safety. Next, let the prototype transformed and modular. Then filter through the original limit conditions of military community and building escape evacuation safety condition. Last, we get the safe and suitable module of ding kinds military community. With this result, hope to find the coping strategies for the escape evacuation safety of historical buildings. The module retread military community space and let the original space elasticized. Moreover, the module can respond to the spatial scale of different function, and bring the maximum efficiency in the use of space.

En öde ö som flyter runt : en kvalitativ studie av hur mobila och stationära förskolepedagoger uppfattar de organisatoriska förutsättningarna för att hantera en dubbel enhet / A deserted island floating around : a qualitative study about how mobile and stationary preschool pedagogues perceive the organizational condition for managing a dual unit

Wickholm, Jennie January 2017 (has links)
The purpose of this study is to examine how mobile and stationary pedagogues experience the cooperation between the two units and how the pedagogues perceive the organizational conditions for managing a dual unit. Furthermore is the study also examine whether there are any different perceptions of working methods in each other's activities and if this has an impact on the children at preschool. In order to be able to answer these questions, I have chosen to make qualitative interviews at two different stationary preschools and two different mobile units/buses. I have interviewed four pedagogues, two from stationary units and two from mobile units. In my study I can see patterns in that bus pedagogues perceive themselves as be an ”own preschool” or ”own island” where they express "take care" of themselves. Nor do they perceive that they need to adapt to what’s happening on the preschool, for example, in case of illness. But they have a need to belong to the "house" when it comes to getting help during planning times. The stationary pedagogues perceive as the bus pedagogues do not see the entire preschool as a common organization that the bus pedagogues only cares for their own needs. The stationary pedagogues perceive that the mobile pedagogues exclude themselves but the mobile pedagogues perceive that they get excluded. The result of this study points that management should be aware of the strong impact of previous traditions and approaches in a working group or individual. Without clear leadership, too much space is given to the pedagogues own "profit-making" purposes, which can have an impact on the children's opportunities and to become in the preschool environment.

When soliders become refugees: Surveillance and fear among Rwandan former soliders living in Cape Town, South Africa

Ncube, Florence January 2017 (has links)
Magister Artium - MA (Anthropology/Sociology) / This study examines the fears of Rwandan army deserters who oppose President Kagame, of being found by the External Security Organisation (ESO), a Rwandan spy organisation meant to sniff them out wherever they are in exile: in this case Cape Town, South Africa. The army deserters are perceived as both a political and military threat to the survival of President Kagame. I argue that the fear of being hunted is a real threat which (re)produces 'militarised identities' as these former soldiers employ their military training skills to hide from the ESO in South Africa. In this I employ Foucault's (1977) concept of 'panopticism' to examine these army deserters' experiences of surveillance by the ESO and also Vigh's (2006) concept of 'social navigation' to understand how the army deserters 'scan' and manoeuvre the exile terrain. In substantiating the thesis argument, my study draws from six in-depth interviews and conversations with Rwandan army deserters living in Cape Town. It also made use of thematic analysis, drawing themes from the data on which it is based.

Uncertainty evaluation for in flight radiometric calibration of earth observation sensors / Avaliação da incerteza na calibração radiométrica de sensores de observação da terra

Cibele Teixeira Pinto 07 July 2016 (has links)
The absolute radiometric calibration is a prerequisite for creating high-quality science data, and consequently, higher-level Earth observation sensors products. The radiometric calibration uncertainty is the key that describes the reliability of calibration results. The main objective of this present work was to develop a method to evaluate the uncertainties inherent in the in-flight absolute radiometric calibration of Earth observation sensors. The methodology developed and tested confirms the hypothesis that the method proposed here is compatible and comparable with other methods practiced by the international science community of satellite radiometric calibration. The uncertainties were determined for two methods of absolute radiometric calibration: reflectance based approach and cross-calibration method. The reflectance-based approach was performed using four different reference surfaces: (a) west part of the Bahia State, Brazil; (b) Atacama Desert, Chile; (c) Algodones Dunes, USA; and (d) South Dakota State University (SDSU) site, USA. Regarding the reflectance-based approach, the main sources of uncertainty are: (a) the instruments used for the reference surface characterization; (b) atmosphere characterization parameters; (c) surface reflectance factor; and (d) radiative transfer code (MODTRAN). The spectroradiometer instrumental uncertainties in laboratory were lower than 1\%. The reference panel relative uncertainties were less than 0.25\%. The columnar water vapor was derived from the spectral band of the solar photometer centered on 940 nm with an uncertainty lower than 5\%. The aerosol optical depth relative uncertainties ranged from 2 12\% in Brazil, 1 5\% in Chile, 1-11\% in Algodones Dunes and less than 1.2\% in SDSU site. The most important information related to the reflectance based method is the retrieved surface reflectance factor at the time of sensor overpass the site measured in field. The relative uncertainty of the Algodones Dunes and Atacama Desert reflectance factor was lower than 5\%; and the relative uncertainty of Brazil and SDSU reflectance factor ranged from 3\% to 10\%. The second major source of uncertainty was the accuracy of MODTRAN (2\%). The final uncertainty of the TOA radiance predicted by MODTRAN in Brazil and in SDSU site was lower than 10\%. The final uncertainty of the TOA radiance predicted by MODTRAN in Atacama Desert and in Algodones Dunes site was lower than 5.5\%. These values are the overall total uncertainty of the reflectance based method in the spectral range of 350 to 2400 nm. The cross calibration between both MUX and WFI on-board CBERS 4 and the OLI on board Landsat-8 was performed using the Libya-4 and Atacama Desert sites. During the cross calibration it is necessary to correct the intrinsic offsets between two sensors caused by Spectral Response Function (SRF) mismatches using a spectral band adjustment factor (SBAF). Thus, one of the sources of uncertainty in the cross calibration is the SBAF, which depend on the uncertainty of the target spectral profile and the SRF uncertainty of the two sensors. Here, the SBAF was estimated with an uncertainty lower than 2\%. The overall total uncertainty achieved here with cross calibration method using the Libya-4 and Atacama Desert sites was less than 6.5\%. The dominant source of uncertainty in cross calibration is the uncertainty associated with the sensor selected as reference. The OLI produces data calibrated to an uncertainty of less than 5\% in terms of radiance. Brazil now has a quantitative indication of the quality of the absolute calibration final results. In addition, the country now has autonomy and reliability in the data provided by sensors of national Earth observation program. / A capacidade de detectar e quantificar as mudanças na superfície terrestre utilizando dados de sensoriamento remoto depende de sensores de observação da Terra que forneçam medições precisas e consistentes ao longo do tempo. Uma etapa essencial para garantir esta qualidade e consistência nos dados é a realização da calibração radiométrica absoluta, cuja confiabilidade é quantificada por meio do cálculo das incertezas envolvidas no processo. O objetivo principal deste trabalho é apresentar um método para avaliar as incertezas inerentes às missões de calibração radiométrica absoluta de sensores de observação da Terra após seu lançamento. A metodologia desenvolvida e testada confirma a hipótese de que o método proposto é compatível e comparável com outros métodos praticados pela comunidade científica internacional de calibração radiométrica de sensores abordo de satélite. As incertezas foram determinadas para dois métodos de calibração radiométrica absoluta: reflectance-based e calibração cruzada. O método reflectance-based foi realizado em quatro superfícies de referência distintas: (a) oeste do estado da Bahia, Brasil; (b) Deserto do Atacama, Chile; (c) Algodones Dunes, EUA; e (d) South Dakota State University (SDSU), EUA. As principais fontes de incerteza relacionadas ao método reflectance based são: (a) os instrumentos utilizados para a caracterização da superfície de referência; (b) os parâmetros de caracterização da atmosfera; (c) o fator de reflectância da superfície; e (d) o modelo de transferência radiativa (MODTRAN). As incertezas instrumentais relacionadas ao espectrorradiômetro foram menores que 1\%. As incertezas da placa de referência foram menores que 0,25\%. O conteúdo de vapor dágua foi derivado da banda espectral do fotômetro solar centralizada em 940 nm com uma incerteza menor que 5\%. A incerteza relativa da profundidade óptica do aerossol variou entre 2 e 12\% no Brasil, 1 a 5\% no Chile, 1 a 11\% em Algodones Dunes e foi menor que 1,2 \% na SDSU. A informação de maior importância do método reflectance-based é o fator de reflectância da superfície medido no momento em que o sensor sobrevoou a superfície em campo. A incerteza relativa do fator de reflectância de Algodones Dunes e do Deserto do Atacama foi menor que 5\% enquanto do Brasil e na SDSU variou entre 3 e 10\%. A segunda maior fonte de incerteza se referiu à precisão do MODTRAN (2\%). A incerteza final da radiância no topo da atmosfera estimada pelo MODTRAN no Brasil e na SDSU foi menor que 10\%. A incerteza final da radiância no topo da atmosfera estimada pelo MODTRAN no Deserto do Atacama e em Algodones Dunes foi menor que 5,5\%. Esses valores correspondem à incerteza total global do método reflectance based para a região espectral entre 350 e 2400 nm. A calibração cruzada dos sensores MUX e WFI a bordo do CBERS-4 com o sensor OLI a bordo do Landsat-8 foi realizada utilizando duas áreas distintas: Libya-4 e o Deserto do Atacama. Durante o processo de calibração cruzada é necessário corrigir as diferenças das funções de resposta espectral (SRF) dos dois sensores envolvidos. Essa correção é realizada mediante aplicação do fator de ajuste de banda espectral (SBAF). Assim, uma das fontes de incertezas no processo de calibração cruzada é o próprio SBAF, no qual depende da incerteza do perfil espectral do alvo e da incerteza da SRF dos dois sensores (sensor de referência e sensor a ser calibrado). Neste trabalho, o SBAF foi estimado com uma incerteza menor que 2\%. A incerteza total global no método de calibração cruzada utilizando o Deserto do Atacama e a Líbya-4 foi menor que 6,5\%. A fonte de incerteza dominante na calibração cruzada é a incerteza associada ao sensor selecionado como referência. O sensor OLI produz dados calibrados de radiância com uma incerteza menor que 5\%. O Brasil agora possui uma indicação quantitativa da qualidade do resultado final da calibração radiométrica absoluta. Além disso, o país também passa a possuir autonomia e confiabilidade nos dados disponibilizados por sensores do programa nacional de observação da Terra, como por exemplo, o CBERS 4.

Estratigrafia de alta resolução dos estágios iniciais de rifteamento, Bacia De Sergipe-Alagoas, Brasil.

Kifumbi, Carrel January 2017 (has links)
A transição entre as duas primeiras fases de rifteamento é caracterizada por um aumento da atividade tectônica e uma reestruturação da bacia. Na Bacia de Sergipe-Alagoas, essa passagem é marcada pela mudança dos sistemas deposicionais e das direções de paleocorrentes entre as Formações Serraria e Feliz Deserto. A sucessão sedimentar estudada pode ser subdividida em três unidades deposicionais que denotam contextos paleogeográficos diferentes. A unidade I, equivalente ao topo da Formação Serraria, é caracterizada por corpos arenosos amalgamados de canais fluviais entrelaçados. A unidade II, correspondente à base da Formação Feliz Deserto, é caracterizada pela intercalação entre associações de fácies de canais fluviais anastomosados e planície de inundação. A unidade III, equivalente à maior parte da Formação Feliz Deserto, é caracterizada por depósitos deltaicos. Os dados de paleocorrentes da unidade I indicam que o depocentro da bacia nessa fase está localizado provavelmente fora dos limites dos atuais estados de Sergipe e Alagoas e a unidade III apresenta um padrão de paleocorrentes polimodal sugerindo influxo sedimentar a partir de vários flancos A baixa quantidade de medidas de paleocorrentes da unidade II não permite tirar conclusões sobre a localização exata do depocentro. A mudança de sistema deposicional e de direção das paleocorrentes sugere que as unidades descritas foram depositadas em diferentes estágios evolutivos de rifte. As unidades I e II foram depositadas em uma ampla bacia rasa durante o Trato de Sistema Tectônico de Início de Rifte (Kuchle e Scherer, 2010) caracterizado por baixa taxa de criação de espaço de acomodação e baixa atividade tectônica. Pode se inferir que esses parâmetros aumentam levemente na unidade II pela preservação de sedimentos finos externos ao canal. A unidade III por sua vez sugere um contexto de bacias mais profundas com alta taxa de criação de espaço de acomodação associada à fragmentação da ampla bacia em meio-grábens distintos. Esse estágio é denominado de Trato de Sistema Tectônico de Desenvolvimento de Meio-Gráben (Kuchle e Scherer, 2010). O contato entre os dois tratos é marcado por uma superfície de inundação indicando que a transição é extremamente rápida e marcada por uma mudança radical na geometria da bacia. / The transition between the first two stages of rifting is characterized by an increase in tectonic activity and a restructuring of the basin. In the Sergipe-Alagoas Basin, this passage is marked by the change of depositional systems and of paleocurrent directions between Serraria and Feliz Deserto formations. The sedimentary succession studied can be subdivided into three depositional units denoting different paleogeographic contexts. Unit I, equivalent to the top of Serraria Formation, is characterized by multy-storey and multi-lateral amalgamated sandstone bodies of braided fluvial channel facies association. Unit II, which corresponds to the base of Feliz Deserto Formation, is characterized by the intercalation between anastomosed fluvial channel and floodplain facies associations. Unit III, equivalent to the major part of Feliz Deserto Formation, is characterized by delta deposits. The paleocurrent direction of unit I indicates that the basin depocenter during this fase was probably located outside the limits of the actual states of Sergipe and Alagoas and unit III displays a polymodal paleocurrent pattern suggesting sedimentary influx from several flanks The low amount of paleocurrent measurement of unit II does not allow drawing conclusions about the exact location of the depocenter. The change of depositional system as well as paleocurrent direction suggests that the described units were deposited in different evolutionary stages of rifting. Units I and II were deposited in a wide shallow basin during the Rift Initiation System Tract (Kuchle and Sherer, 2010) characterized by low rate of accommodation space creation and low tectonic activity. It can be inferred by the preservation of fine sediments external to the channel that, in unit II, these parameters increase slightly. Unit III in turn suggests a context of deeper basins with high rate of accommodation space creation associated with the fragmentation of the wide basin in distinct half-grabens. This phase is called Half-Graben Development System Tract (Kuchle and Sherer, 2010). The contact between these two stages is marked by a flooding surface indicating that the transition is extremely rapid and marked by a radical restructuration in the geometry of the basin.

A transição entre as duas primeiras fases de rifteamento é caracterizada por um aumento da atividade tectônica e uma reestruturação da bacia. Na Bacia de Sergipe-Alagoas, essa passagem é marcada pela mudança dos sistemas deposicionais e das direções de paleocorrentes entre as Formações Serraria e Feliz Deserto. A sucessão sedimentar estudada pode ser subdividida em três unidades deposicionais que denotam contextos paleogeográficos diferentes. A unidade I, equivalente ao topo da Formação Serraria, é caracterizada por corpos arenosos amalgamados de canais fluviais entrelaçados. A unidade II, correspondente à base da Formação Feliz Deserto, é caracterizada pela intercalação entre associações de fácies de canais fluviais anastomosados e planície de inundação. A unidade III, equivalente à maior parte da Formação Feliz Deserto, é caracterizada por depósitos deltaicos. Os dados de paleocorrentes da unidade I indicam que o depocentro da bacia nessa fase está localizado provavelmente fora dos limites dos atuais estados de Sergipe e Alagoas e a unidade III apresenta um padrão de paleocorrentes polimodal sugerindo influxo sedimentar a partir de vários flancos A baixa quantidade de medidas de paleocorrentes da unidade II não permite tirar conclusões sobre a localização exata do depocentro. A mudança de sistema deposicional e de direção das paleocorrentes sugere que as unidades descritas foram depositadas em diferentes estágios evolutivos de rifte. As unidades I e II foram depositadas em uma ampla bacia rasa durante o Trato de Sistema Tectônico de Início de Rifte (Kuchle e Scherer, 2010) caracterizado por baixa taxa de criação de espaço de acomodação e baixa atividade tectônica. Pode se inferir que esses parâmetros aumentam levemente na unidade II pela preservação de sedimentos finos externos ao canal. A unidade III por sua vez sugere um contexto de bacias mais profundas com alta taxa de criação de espaço de acomodação associada à fragmentação da ampla bacia em meio-grábens distintos. Esse estágio é denominado de Trato de Sistema Tectônico de Desenvolvimento de Meio-Gráben (Kuchle e Scherer, 2010). O contato entre os dois tratos é marcado por uma superfície de inundação indicando que a transição é extremamente rápida e marcada por uma mudança radical na geometria da bacia. / The transition between the first two stages of rifting is characterized by an increase in tectonic activity and a restructuring of the basin. In the Sergipe-Alagoas Basin, this passage is marked by the change of depositional systems and of paleocurrent directions between Serraria and Feliz Deserto formations. The sedimentary succession studied can be subdivided into three depositional units denoting different paleogeographic contexts. Unit I, equivalent to the top of Serraria Formation, is characterized by multy-storey and multi-lateral amalgamated sandstone bodies of braided fluvial channel facies association. Unit II, which corresponds to the base of Feliz Deserto Formation, is characterized by the intercalation between anastomosed fluvial channel and floodplain facies associations. Unit III, equivalent to the major part of Feliz Deserto Formation, is characterized by delta deposits.
