Thesis advisor: George O'HarIn these three longer short stories I explore the theme of "sense of place," of the geographic and psychological confusion of the world and the people in and on it. The first piece, "Cartography," is the story of a woman who, despite living in a large and vibrant city, struggles to find herself within it. The second piece, "The Birds," is the story of a man, Adam, who searches to define himself against the earth and attempts to reject his own embodiment, ultimately failing, but in doing so finds something else. The third piece, "Men Shall Know Nothing of This" (also the title of a Max Ernst painting) is a brief history of a city — and how it continues even when it appears to be dying — past its industrial prime, told through the interactions of four characters with the main road

Full textAbstract:
As a vast photographic tableau of images sourced from antiquity, the Renaissance and early-twentieth-century popular media, Aby Warburg’s Mnemosyne Atlas (1924-29) was a means to formulating a fluid archive of cultural memory. In this exegesis, I show how Warburg’s mosaic of disparate remnants from the past has resonances with the mythopoetic structures that underpin my studio practice. Specifically, I adopt mythopoetics as both a conceptual and methodological strategy, as a vehicle for exploring first-person narratives and their capacity to formulate more defined and meaningful concepts of historical consciousness.
This exegesis examines the archive as a metonymic framework that supports the ebb and flow of narrative context within the historical, cultural and subjective realms. Through references to the nature of the archive outlined in Jacques Derrida’s Archive Fever (1994) and Walter Benjamin’s concept of material history, I discuss the capacity for artefacts to inform both our historical awareness and current everyday experiences. The act of collecting as a mode of seeking out alternate forms of knowing and interpreting the past presents a counter-argument to the need to totalise historical narratives.
Within this context, I draw parallels between the archival projects of Warburg and Benjamin and the contemporary works of W.G. Sebald, Gerhard Richter and Anselm Kiefer. Specifically, I investigate how Sebald’s literary works poetically explore the historical structures and practices that continue to give meaning to the every day and consider this in relation to Richter’s photographic archive Atlas, (years–ongoing) in which the artist references a mapping of identity through the blending of personal and collective cultural locations. Similarly Kiefer’s artists’ books evidence a conjuncture of first-person narrative and collective history that evokes a continuous liminal transition between present and past experience.Thesis (Professional Doctorate)

Full textAbstract:
The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in 2014 July. It pursues three core programs: the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2), Mapping Nearby Galaxies at APO (MaNGA), and the Extended Baryon Oscillation Spectroscopic Survey (eBOSS). As well as its core program, eBOSS contains two major subprograms: the Time Domain Spectroscopic Survey (TDSS) and the SPectroscopic IDentification of ERosita Sources (SPIDERS). This paper describes the first data release from SDSS-IV, Data Release 13 (DR13). DR13 makes publicly available the first 1390 spatially resolved integral field unit observations of nearby galaxies from MaNGA. It includes new observations from eBOSS, completing the Sloan Extended QUasar, Emission-line galaxy, Luminous red galaxy Survey (SEQUELS), which also targeted variability-selected objects and X-ray-selected objects. DR13 includes new reductions of the SDSS-III BOSS data, improving the spectrophotometric calibration and redshift classification, and new reductions of the SDSS-III APOGEE-1 data, improving stellar parameters for dwarf stars and cooler stars. DR13 provides more robust and precise photometric calibrations. Value-added target catalogs relevant for eBOSS, TDSS, and SPIDERS and an updated red-clump catalog for APOGEE are also available. This paper describes the location and format of the data and provides references to important technical papers. The SDSS web site, http://www.sdss.org, provides links to the data, tutorials, examples of data access, and extensive documentation of the reduction and analysis procedures. DR13 is the first of a scheduled set that will contain new data and analyses from the planned similar to 6 yr operations of SDSS-IV.

Full textAbstract:
Understanding mysteries of a brain represents one of the great challenges for modern science. Functional magnetic resonance imaging (fMRI) has two features that make it unique amongst other imaging modalities used in behavioral neuroscience. First, it can be entirely non-invasive and second, fMRI has the spatial and temporal resolution to resolve patterns of neuronal activity across the entire brain in less than a minute. fMRI indirectly detects neural activity in different parts of the brain by comparing contrast in MR signal intensity prior to and following stimulation. Areas of the brain with increased synaptic and neuronal activity require increased levels of oxygen to sustain this activity. Enhanced brain activity is accompanied by an increase in metabolism followed by increases in blood flow and blood volume. The enhanced blood flow usually exceeds the metabolic demand exposing the active brain area to high level of oxygenated hemoglobin. Oxygenated hemoglobin increases the MR signal intensity that can be detected in MR scanner. This relatively straight forward scenario is, unfortunately, oversimplified. The fMRI signal change to noise ratio is extremely small. In this work a quantitative analysis strategy to analyze fMRI data was successfully developed, implemented and optimized for the rat brain. Therein, each subject is registered or aligned to a complete volume-segmented rat atlas. The matrices that transformed the subject's anatomy to the atlas space are used to embed each slice within the atlas. All transformed pixel locations of the anatomy images are tagged with the segmented atlas major and minor regions creating a fully segmented representation of each subject. This task required the development of a full 3D surface atlas based upon 2D non-uniformly spaced 2D slices from an existing atlas. A multiple materials marching cube (M3C) algorithm was used to generate these 1277 subvolumes. After this process, they were coalesced into a dozen major zones of the brain (amygdaloid complex, cerebrum, cerebellum, hypothalamus, etc.). Each major brain category was subdivided into approximately 10 sub-major zones. Many scientists are interested in behavior and reactions to pain, pleasure, smell, for example. Consequently, the 3D volume atlas was segmented into functional zones as well as the anatomical regions. A utility (program) called Tree Browser was developed to interactively display and choose different anatomical and/or functional areas. Statistical t-tests are performed to determine activation on each subject within their original coordinate system. Due to the multiple t-test analyses performed, a false-positive detection controlling mechanism was introduced. A statistical composite of five components was created for each group. The individual analyses were summed within groups. The strategy developed in this work is unique as it registers segments and analyzes multiple subjects and presents a composite response of the whole group. This strategy is robust, incredibly fast and statistically powerful. The power of this system was demonstrated by mapping the olfactory system of a rat brain. Synchronized changes in neuronal activity across multiple subjects and brain areas can be viewed as functional neuro-anatomical circuits coordinating the thoughts, memories and emotions for particular behaviors using this fMRI module.

Full textAbstract:
My practice-based PhD investigates how the gathering of visual information through the photographic camera, together with the visual strategies involved in the organisation and configuration of specific groups of images are key processes in the constitution of meaning. I use my own practice to ‘de-construct’ these ideas, to help me understand the role of photography in recording information with the purpose of piecing the gathered material together in an atlas, using the montage, and to finally present the result using the grid as a structure that holds all the photographs together. One of the main aspects that underlies this research is the role that photography plays in recording information and the way in which historically, photography and archives are constituted together. In the last three decades, the concept of the archive has been given increasing prominence in the field of art. A review of the literature theorising the articulation between archives and art shows that in fact photographs and visual imagery are at the core of most archives. Therefore, the role of photography is one of the key elements to consider in the discussion between archives and art. My research tries to recover, actualise and visually add to some of the discourses that focus on the singular relationship established between photography and archives. For this I will analyse my own work and artworks that use photography as the first means to gather visual information. However, in the construction of these artworks, artists use a range of organisational strategies borrowed from archives, collections and visual atlases. Therefore, the practices discussed in the thesis including my own neither constitute, nor belong to archives, collections, or visual atlases of images. What they do is to borrow strategies from all these systems, moving between them to create singular artworks that have a hybrid character.

Full textAbstract:
Maps and atlases are traditionally convenient documents for representing the surface of the earth. They provide an impression of spatial relationships and facilitate an appreciation of geographical and environmental characteristics. They are essential tools for creating an awareness of the world beyond the limits of our experience. Maps can also inform readers on the flow of cultural or economic influences, because they show localities in relation to their neighbours. Furthermore, they capture the reader's imagination by provoking the desire for adventure and exploration. Occasionally maps are also censored because they are an efficient means of indicating strategic features. This project concerns the historical and contemporary examples of communicating information visually by analysing a selection of conventional literary and visual sources, which informs the research. It includes graphic forms that present abundant data, for example, atlases and texts on the architectural history of Central Asia, Tibet, China and Japan. The studio works will examine illustration, draughtsmanship, rendering, and textual/visual imagery. The outcome will be an illustrated atlas of traditional architecture in the earthquake zones of Central Asia (Xinjiang), Tibet, China, Japan and related areas. The graphic format is used as a narrative for the communication of environmental, cultural and architectural data of the region. The atlas is also intended to present the subject in a holistic form in relation to environmental influences on the structures and materiality of buildings, and the broader field of history.

Full textAbstract:
Medical imaging has revolutionized cancer care and its use has grown massively over the past several decades. Images are increasingly stored in large digital image repositories such as hospital Picture Archiving and Communication System, which will hopefully provide a wealth of information on patient conditions and therapy outcomes as cancer diagnosis and therapy moves from 'one size fits all' to more personalized approaches tailored to each particular patient. However, converting the unstructured avalanche of data at thousands of different hospitals into clinically valuable biomarkers and tools requires that the images of different patients can be compared and efficiently searched. Our research aims to develop novel methods to compare whole-body scans of multiple patients; methods which incorporate 'intelligent' prior knowledge of the internal structure of the human body, as opposed to current methods of image registration which mostly rely on matching the voxel intensities and disregard their anatomical meaning. We develop computational methods for accurate and reliable automated localization of anatomical structures in whole-body images, which will help to automate key steps in cancer diagnosis and radiation treatment planning and save expensive clinicians' time while improving the reliability of their decisions. Conventional approaches to determining spatial correspondences between pairs or sets of images in medical imaging typically rely on image registration methods. There have been considerable advances in registration of multiple images of the same patient taken at different time-points, known as longitudinal studies. However, conventional methods, which rely on optimizing certain integral functions of voxel values over the entire image, are unreliable when applied to aligning whole-body images of different patients. Whole-body Computed Tomography (CT) images contain many different anatomical structures whose physical attributes and consequent appearance can be highly variable between patients. This substantial, but normal, variability is further increased by the presence of pathologies such as tumours and non-cancerous diseases, surgical interventions and degenerative changes due to aging as well as different patterns of contrast agent uptake. Conventional registration methods often get trapped in local minima that abound in such images, resulting in unreliable and inaccurate anatomical correspondences. The methods developed in this thesis tackle the problem of inter-patient registration by incorporating prior anatomical knowledge into parts-based graphical models that accurately and reliably localize arbitrary skeletal and soft-tissue anatomical landmarks in whole-body clinical oncology scans. We optimize parts-based graphical models called Pictorial Structures for accurate and reliable landmark localization in CT images and introduce novel methods that replace standard population models by models personalized to the particular patient. We also propose methods that further improve landmark localization while minimizing, as far as possible, the high costs of ground-truth annotation by expert radiologists. We do this by automatically discovering new landmark correspondences from a database of partially annotated images. The performance of the algorithms developed in my thesis is evaluated on a large database of clinical lung cancer PET/CT scans, showing superior accuracy and reliability of landmark localization compared to conventional methods.

Full textAbstract:
My concern in this thesis is with the production of British school atlases between 1870 and 1930. I interpret this particular genre of map and book through the rich resource of the Bartholomew Archive, which holds the business and personal records of the Edinburgh mapmaking firm John Bartholomew & Son. School atlases were instrumental in the dissemination of geographical knowledge at a time when geographers were moulding their subject’s place in the universities and schools in Britain and in parts of the Empire beyond. This thesis builds on concepts in the history of the book, the history of the map and archive history in order to gain knowledge about the people and processes through which this particular type of mapbook was produced, moved and used, and to understand how it was bound up in the development of a discipline. In chapter 1, I outline the main themes of the thesis. The theoretical and methodological ideas underlying it are reviewed in detail in chapter 2. Chapter 3 illuminates the themes threading through the following empirical chapters, providing insight into school atlas production through a consideration of Bartholomew’s production ledgers and what these reveal about the nature of geographical publishing. Interactions between individual atlas producers form the focus of chapter 4, particularly negotiations between publishers, mapmakers, geographers and other professionals over the meaning of ‘author’. In chapter 5, I go on to address atlas production in relation to the pedagogy of regional geography used in schools and, particularly, its impact on school atlases for pupils in ‘local’ settings across the UK. This leads in chapter 6 to an interpretation of how this localising of school atlases was adapted to readers’ locations throughout the British Empire. Questions about readers’ role in the shaping of textual meaning are considered further in chapter 7, which draws on specific instances of producer-reader-atlas interactions to support the argument that reading and reviewing were processes conducted not only, as I show, by readers on the published text but, as I also indicate, they were practices performed by both producers and readers during atlas production. My findings in this thesis shed light on the publishing history of British school atlases, hitherto largely unexamined by historians of the map and historians of geography, and they contribute to our understanding of the production, movement and use of geographical knowledge in the late nineteenth and early twentieth centuries.

Full textAbstract:
The definition of optimal selection criteria for maximizing the response rate to Cardiac Resynchronization Therapy (CRT) is still an issue under active debate. Recent clinical approaches propose a classification of patients into classes of mechanisms that could lead to heart failure and study their response to the therapy. In this line of research, the computation of a metric between the motion and deformation patterns of a given subject and well identified classes of CRT responders is considered in this thesis, as the basis of a new strategy to compute patient selection indexes. The thesis proposes first an improved design for the construction of statistical atlases of myocardial motion and deformation, and applies it to the characterization of populations of patients involved in CRT. The added-value of our approach is highlighted in a clinical study, applying the methodology to a large population of patients with a given pattern of dyssynchrony (septal flash) and understanding the link between its correction and CRT response. Finally, we propose a method to extend the analysis to the comparison of individuals to reference populations, either healthy or pathological, using manifold learning techniques to model a disease as progressive deviations from normality along a manifold structure, and demonstrate the potential of our method for inter-subject comparison in CRT patients.La definición de un criterio óptimo para mejorar la respuesta a la Terapia de Resincronización Cardíaca (TRC) sigue siendo un debate abierto. Estudio clínicos recientemente publicados proponen clasificar pacientes según diversos mecanismos patofisiológicos que pueden inducir insuficiencia cardíaca y estudian su respuesta a la terapia. Siguiendo esta línea de investigación, esta tesis considera el cálculo de una distancia entre los patrones de movimiento y deformación de un individuo y las clases de respondedores a la TRC, siendo la base de una nueva estrategia para calcular índices para seleccionar pacientes. Esta tesis presenta primero un método para construir un atlas estadístico de movimiento y deformación miocárdica, y su aplicación posterior a la caracterización de poblaciones de potenciales candidatos a la TRC. El valor añadido de nuestro método se enfatiza en un estudio clínico, en el cual se aplica la metodología a una gran población de pacientes con un patrón específico de disincronía cardíaca (llamado septal flash), y se relaciona su corrección y la respuesta a la TRC. Finalmente, se extiende el método para comparar individuos a una población de referencia, sana o patológica, usando técnicas de manifold learning para representar una patología como una desviación progresiva de la normalidad, con una estructura no lineal específica, y se demuestra el potencial de nuestro método para comparar entre sí candidatos a la TRC.

Full textAbstract:
The economic competition between the Netherlands, France and England is documented in the atlases published in Amsterdam, Paris and London between 1500 and 1800. However, the relationship between mapping and economic processes remains mostly unexplored in the history of cartography. World-system theory has application to the history of cartography in the early modern period for identifying the linkages between cartography and long-term economic processes.This research analyzes the production of maps, specifically in world and maritime atlases, in these three cities as the geographic expression of the emergent capitalist world system in early modern Europe. The economic concepts of core and periphery as proposed by Immanuel Wallerstein are defined cartographically in the structural morphologies of Dutch, French and English atlases published in this period. Each country mapped itself as a core and such cartographic self-definitions reflect their individual geographic and economic contexts. The Netherlands and England created core atlases in the sixteenth century that evolved in support of business and transport as well as state interests. The French core atlas initiated at the end of the seventeenth century was a governmentally sponsored survey dedicated primarily toward state administration control. The Netherlands, Fance and England also mapped their continental and extra-European peripheries in world and maritime atlases. Dutch engagement in long-distance trade in agricultural commodities created world-system commodity chains of production. Dutch maritime atlases defined these networks of commercial opportunity for the first time. The creators of the first printed world atlases, Dutch cartographers also structured their productions of atlases as a commercial enterprise marketed toward an international clientele. Dutch maritime atlases were an important innovation and Amsterdam atlas publication dominated cartography in the seventeenth century. English publishers adopted Dutch innovations in map production and succeeded to dominance in printing atlases whose structural morphology embodies a world-system of commodity networks. The relationship of cartography to long-term economic processes is demonstrated by the Dutch and English atlases. Early modern world atlases portray the cartographic world-view of core and periphery. The maritime atlases provide the first portrayal of long-distance trade networks that continue to characterize the capitalist exchange of commodities globally.

Full textAbstract:
School Historical Atlases and Historical Atlases mainly designed for educational uses had a significant impact and role in the diffusion and propagation of the idea of nation-state and, in a specular way, national school system played a fundamental role in the diffusion of such works. The role of Historical Atlases in the development of nationalistic narrations has recently been extensively studied by some scholars in their works such as Jeremy Black, Patrick Lehn and Sylvia Schraut. In particular, Deutschlandbilder: Historische schulatlanten zwischen 1871 und 1990 : Ein handbuch by Lehn (2008) and Kartierte Nationalgeschichte by Schraut (2011) focused exclusively on the process of conception, creation and production of school historical atlases, and the relationships between those atlases’ authors and publishers and various governmental (the ministries of education above all) and para-governmental offices (such as geographic and cartographic societies and history teachers’ associations).
Border Regions have long been subjects of historiographical, geographical and cartographical research. As Border Regions are natural subjects of border changes and claims, there has been a long history of nationalistic cartographic production created to strengthen or counterpoise such claims. For this reason, Border Regions have become the ‘designed battlefield’ for opposing ‘national cartographies’. Nationalistic cartographic productions on Border Regions involve several types of cartographies, from postage stamps maps to atlases, including historical atlases.
The scope of my PhD thesis is to analyse how a particular Border Region, the territory which is now known as the Autonomous Province of Bolzano – South Tyrol, has been depicted in the cartographic production of the Historical Atlases created by the opposing nationalisms, the German and the Italian ones, which, during most of the 19th and 20th centuries, wrestled for its control. The analysis is limited to historical atlases published between the end of the processes of national unification of both Germany and Italy (Germany was unified in 1871 and Italy acquired its capital Rome in 1870. For this reason, the starting date used for this thesis is 1871) and the aftermath of the Second World War (early 1960s). More precisely, this thesis speculates that Border Regions’ maps in Historical Atlases (in this case, maps that depict South Tyrol) have been used as actual ‘workshops’ for cartographic propaganda, in which new features are tested. The timeline choice resides in the fact that this period is the one in which a national consciousness was developed by the nation states and in which there was a high degree of continuity in nationalistic propaganda policies. After the end of the Second World War, aggressive nationalistic policies were gradually, but not entirely, abandoned even if they were still enforced at the beginning of the 1960s. The choice of only analysing school historical atlases is dictated by the fact that, even if the production of this kind of atlas was never (neither in Germany, nor in Italy) officially under the control of the state, the development of nation states could be displayed through historical atlases, and national school system played a significant role in the propagation of this kind of atlases.
For this project, a series of qualitative and quantitative analysis of the maps’ features have been developed. The maps’ features that has been analysed in the project include type of maps (i.e. cultural, military, economic, ethnographical etc.), time period covered (i.e. medieval, modern etc.), size of maps, toponyms, use of colours and border adjustments. The thesis, organized in four articles plus introduction and conclusions, highlights the pioneering importance for the cartographic propaganda field of Border Regions maps contained in historical atlases.L’obiettivo della tesi è quello di analizzare le carte riguardanti il Sudtirolo negli atlanti storici per la scuola tedeschi e italiani prodotti dalla fine dei processi di unificazione nazionale al secondo dopoguerra e di dimostrare come queste carte siano stati dei veri e propri laboratori per la sperimentazione di nuove tecniche di propaganda cartografica. Le carte analizzate sono state in tutto 420, tratte da 25 edizioni dei seguenti atlanti storici: Putzgers Historischer Schul-Atlas, Westermann Atlas zur Weltgeschichte, Testo-Atlante di geografia storica generale e d’Italia in particolare e l’Atlante Storico DeAgostini. Lo scopo del primo articolo è quello di fare una review degli studi (in ambito occidentale) sugli atlanti storici, proporre una divisione degli studi in due differenti scuole (Tedesca e Britannico-Americana) ed evidenziare sia gli sviluppi recenti che le lacune della ricerca. Infine, sono anche state avanzate delle proposte per gli sviluppi futuri della ricerca sugli atlanti storici, legate alla necessità di definire una sistematica metodologia storico-geografica per lo studio di questi atlanti (si veda la sezione metodologica per ulteriori dettagli). Il secondo articolo si concentra primariamente sull’atlante Putzger. Prendendo spunto dagli studi sulla propaganda cartografica nazista e sull’analisi culturalista della cartografia, l’articolo si pone come obiettivo quello di analizzare come la cartografia propagandistica dei tempi della Repubblica di Weimar sia stata non solo adottata, ma anche rielaborata all’interno delle contemporanee edizioni del Putzger. Nell’articolo vengono comparate carte propagandistiche e geopolitiche – nell’accezione Ratzeliana del termine – prodotte principalmente dai gruppi völkisch e dalle società geografiche e cartografiche negli anni Venti e Trenta con i loro equivalenti all'interno delle edizioni di Putzger dello stesso periodo. Nell’articolo, oltre ad analizzare l’ampio lavoro di rielaborazione cartografica a scopo propagandistico all’interno del Putzger, viene sottolineata l’importanza delle cosiddette Border Regions (tra cui il Sudtirolo) nella propaganda nazionalistica cartografica. Il terzo articolo è dedicato interamente all’uso dei colori negli atlanti storici. Poiché la maggior parte degli studi sull’uso del colore nella produzione cartografica evidenzia chiaramente il potere comunicativo del colore nella cartografia, è interessante e sorprendente constatare come l'’so di colori per veicolare messaggi diversi da quelli dichiarati non sia stato considerato in questi studi. Il possibile tentativo da parte di alcuni cartografi di fare propaganda nazionalistica attraverso l’uso dei colori nelle mappe e la sua analisi è lasciato a libri sulla propaganda cartografica, a studi sugli atlanti storici e ad articoli sulle mappe tematiche. Per fondere queste due tematiche, nell’articolo è stata fornita un’analisi delle carte dedicate al Sudtirolo tratte dai più importanti atlanti storici tedeschi e italiani per la scuola basata su teorie psicologiche, simboliche e ottiche. L’ultimo articolo può essere considerato quello conclusivo e racchiude la sintesi della ricerca. Nell’articolo viene specificato come le cosiddette Border Regions siano da tempo oggetto di ricerca storiografica, geografica e cartografica e come uno dei temi più importanti della ricerca sulle Border Regions siano le complesse relazioni createsi tra i vari nazionalismi concorrenti nelle zone di confine (come il Sudtirolo) degli imperi multinazionali del XIX e XX secolo. Poiché le Border Regions sono naturalmente soggette ai cambi di confine e a rivendicazioni, esiste sia una lunga storia di produzioni cartografiche nazionalistiche per rafforzare o per contrapporsi a tali rivendicazioni e sia una tradizione di studi su queste produzioni. Le produzioni cartografiche nazionalistiche sulle Border Regions hanno riguardato diversi tipi di cartografie, dalle mappe sui francobolli agli atlanti, tra cui gli atlanti storici. Considerato l'importante ruolo degli atlanti storici nello sviluppo di narrazioni nazionalistiche, non sorprende che molte mappe incluse in queste atlante siano dedicate alle Border Regions, né che le mappe dedicate a queste regioni siano particolarmente raffinate nella cura dei dettagli e dello sforzo propagandistico. Lo scopo dell’ultimo articolo è stato quello di analizzare le mappe delle Border Regions negli atlanti storici scolastici tedeschi e italiani e dimostrare come, nel caso particolare delle mappe che rappresentano il Sudtirolo, siano state veri e propri “laboratori” per la propaganda cartografica. Dallo studio di queste carte sembra emergere l’effettiva natura di “laboratorio” per la propaganda cartografica delle carte dedicate al Sudtirolo negli atlanti storici tedeschi e italiani del periodo preso in considerazione, con una particolare cura per l’uso dei colori, dei toponimi e dei confini linguistici.

Full textAbstract:
A Geographic Information Systems (GIS) atlas of southern African freshwater fish was developed for the SADC countries from natural history collection specimens, hydrological, topographical and climatological data. The primary purpose of the development of the atlas of freshwater fish was the construction of a practical framework to transform vast amounts of existing biological data for use in research and management of aquatic resources. The database of freshwater fish collection specimens that was incorporated into the atlas, was developed in association with ALCOM (Aquatic Resources Management for Local Community Development Programme). The development of advanced computing and GIS technology has increased the scope of biological atlas projects by facilitating the integration of large amounts of spatial data to produce derived databases for specific applications. The atlas of freshwater fish was constructed using TNTmips GIS software as the most practical system available for managing and analysing biological data with a spatial component. The atlas contains 35 180 comprehensive distribution records of 735 species of fish. It has many applications as an inventory of ichthyofaunal spatial biodiversity, including those of conservation planning, environmental assessment and biogeographic research. Biogeographic studies have traditionally been subjective due to the logistical problems of working with large amounts of distribution data, although some small-scale quantitative research has been carried out in the past. The content of the atlas of freshwater fish is tested with respect to these previous studies, on known patterns of freshwater fish distributions, and the analytical capability of the atlas is tested and demonstrated with some new preliminary approaches to the analysis of freshwater fish distributions in southern Africa.

Full textAbstract:
Wind atlases are interactive databases used extensively for preliminary wind resource assessment aimed at optimal wind power development. The selection and processing of wind atlas data are important and will determine the quality of the subsequent WRA (Wind Resource Assessment) phases. This study aims to compare, process, and interpret different wind atlases in determining effective wind resource analysis for 14 different sites in Sweden. The wind atlas data is accessed, parsed, and compared using multiple methodologies to ensure a fair comparison. Several variables like wind speed, wind direction, temperature, production values, etc. are analysed and compared amongst the wind atlas data. The corrected versions of the data are drawn out to conclude and determine how well those databases represent the realistic conditions in a forested site. The data is also compared and validated with measurement data. The results indicate several layers of insights into the wind resource regime. The preliminary results from 14 sites show that New European Wind Atlas (NEWA) and Global Wind Atlas (GWA) agreed sufficiently on the subject of the wind conditions for most of the sites. Methodologies like downscaling and long-term correction introduced to the wind atlas data provided more insights and proved that the database could expand and include more complex wind conditions in the coming years. Furthermore, the comparison and analysis of wind atlas data along with measurement data revealed that NEWA aligned the most to the actual wind conditions for a site. Several uncertainties are considered but more validation and thorough insights in the future could determine and give more affirmations to the idea put forward. Further studies could be conducted along with the inclusion of additional layers, variables, and databases to the wind atlases.

Full textAbstract:
Cette thèse s'inscrit dans le cadre de la construction d'un atlas de glioblastomes (tumeurs cérébrales). En imagerie médicale, un atlas est une image ou un ensemble d'images représentant la distribution statistique d'une population. Souvent, cette distribution prend la forme d'une image représentant la moyenne de la population et d'un ensemble de cartes de déformations entre cette moyenne et chaque image. Pour construire un atlas, il est donc important de correctement définir les transformations entre les images. Les méthodes classiques de recalage considèrent que les deux images sont en correspondance bijective. Or, cela n'est pas le cas dans notre contexte où les deux images n'ont pas le même nombre de composants (une des deux images a la tumeur en plus). Un défi de la thèse a donc été de produire des transformations entre deux images avec des topologies différentes.La première partie de la thèse a porté sur la segmentation de tumeurs cérébrales sur des IRM, permettant ainsi de déterminer précisément l'endroit avec la différence topologique. Alors que la plupart des algorithmes utilisent plusieurs modalités d'acquisition, dans la pratique clinique souvent une seule est dispon- ible (les images pondérées en T1 par exemple). Notre problématique a donc été de proposer un algorithme qui soit performant sur une seule modalité tout en utilisant les informations des bases de données multi-modales pendant l'apprentissage. Pour cela, nous avons utilisé une technique de distillation de connaissances (Hinton et al., 2015). Nous utilisons un réseau maître prenant quatre modalités en entrée pour entraîner un réseau étudiant qui lui ne prend qu'une seule modalité. Une analyse de différentes stratégies de distillation nous permis de montrer dans quels cas ces méthodes sont utiles.La seconde partie de la thèse porte sur le recalage d'une image d'un patient ayant une tumeur vers une image de sujet sain. Nous avons développé une méthode qui prend en compte à la fois les différences géométriques et les différences topologiques entre deux images. Nous nous sommes inspirés des Métamorphoses (Trouvé and Younès, 2005) qui ont été développées pour trans- former la géométrie et les niveaux d'intensité d'une image. Nous avons utilisé un réseau de neurones résiduel pour résoudre les équations aux dérivées partielles qui constituent les métamorphoses. Cela nous permet d'utiliser la méthode en apprentissage, réduisant considérablement le temps d'inférence une fois que le réseau a été entraîné. En outre, nous encourageons une séparation entre les transformations de forme et d'apparence en exploitant un masque de segmentation de la tumeur. De cette façon, nous autorisons les changements d'apparence uniquement dans les régions où des différences topologiques apparaissent entre les images source et cible (par exemple, la tumeur). La méthode de recalage développée constitue ainsi un outil important dans le but de construire un atlas de glioblastomesThe aim of this thesis was to build an atlas of glioblastoma (brain tumors). In medical imaging, an atlas is an image or a set of images that are meant to represent the statistical distribution of a population. Often, this distribution takes the form of an image representing the population average and a set of deformation maps between this mean and each image. To construct an atlas, it is therefore important to correctly define the transformations between the images. Conventional registration methods assume that the two images have only a geometric difference - that is, the first image is the bijective deformation of the other. However, this is not the case in our context, where the two images do not have the same number of components (one of the two images has the tumor in addition). A challenge of this thesis was therefore to produce transformations between two images with different topologies.The first part of the thesis focused on the segmentation of brain tumors on MRI. Indeed, it is important to segment the tumors in order to precisely detect the location with the topological differences. Since our goal is to build an atlas from clinical images, we need a segmentation algorithm that performs well on patients with only one acquisition modality available (such as T1-weighted images). However, most of the state-of-the-art (SOTA) tumor segmentation algorithms need four modalities to perform well. The first goal of this thesis was thus to produce a segmentation algorithm that performs well on test images from a single modality, while leveraging information from multi-modal databases during training. To this end, we proposed a new method based on knowledge distillation (Hinton et al., 2015). We use a teacher network that takes four modalities as input and helps training a student network that takes as input only one of the teacher modalities. We compare the proposed method with several knowledge distillation strategies and show that this kind of methods performs well in a low-data regime and becomes less useful in a high-data regime.The second part of the thesis deals with the registration of a cancerous image onto a healthy image. We developed a method that, in addition to taking into account the geometric differences, it also considers the topological differences between two images. Inspired by Metamorphosis (Trouvé and Younès, 2005), a method developed to transform the geometry and intensity levels of an image, we used a residual neural network to solve the partial differential equations that encode the Metamorphosis framework. This allowed us to reformulate the method in a learning context, which greatly reduced the inference time once the network has been trained. Additionally, we encouraged an anatomically meaningful disentanglement between shape and appearance transformations by leveraging the (previously estimated) segmentation mask of the tumor. In this way, we allow appearance changes only in the regions where topological differences occur between source and target images (e.g., tumor). The developed registration method is thus an important tool in the construction of the glioblastoma atlas

Full textAbstract:
This research will appraise the production and utility of digital atlases in an African context, using personal experience gained through the production of a digital atlas for Swaziland, the opinions obtained from other producers of African digital atlases and relevant literature. Since the 1950s, decision makers and researchers have viewed information as a powerful contributor to national development. Over the past thirty years, developed countries have increased the efficient collation and dissemination of geographic information through the utilization of the digital environment. The development of Geographic Information Systems (GIS) has increased the range of applications attainable in digital mapping projects. Applications have ranged from resource inventories to the monitoring of environmental degradation, crime patterns and service provision. The patchy history of data collection, analysis and mapping in Africa, has had a limiting effect on the ability of countries to identify, plan and control their resources efficiently. Despite the desire to automate the mapping process and reap some of the planning benefits evident in the developed world, Africa has not succeeded in mobilising full technological potential. Political instability, poor infrastructure, the absence of national policy guidelines, and a lack of skilled manpower are some of the issues which have limited utilization. Despite many of the hurdles faced by African countries, automated mapping and analysis technologies are still being pursued. The role of computers in the utilisation of data has become apparent through several means, one of which is the digital atlas. Analytical functions in many of these products allow situation modelling and provide superior graphic displays in comparison to their paper counterparts. Several African countries have embarked on the development of national digital databases and in some cases have produced digital national atlases. The potential to improve resource utilization, service provision and land use planning using these atlases, does exist. The production and utility of these atlases in an African context, however, needs closer assessment. "Computers don't clothe, don't cure, don't feed. Their power begins and ends with information. Their usefulness is therefore strictly linked to the ffectiveness of the information" (Gardner,1993:16).

Full textAbstract:
Quantifying tissue volumes in pediatric brains from magnetic resonance (MR) images can provide insight into etiology and onset of neurological disease. Unbiased volumetric analysis can be applied to large population studies when automated image processing is possible. Standard segmentation strategies using adult atlases fail to account for varying tissue contrasts and types associated with the rapid growth and maturational changes seen in early neurodevelopment. The goal of this project was to develop an automated pipeline and two age-specific atlases capable of providing accurate tissue classification despite these challenges.
The automated pipeline consisted of a stepwise initial atlas-to-subject registration, expectation maximization (EM) atlas based segmentation, and a post-processing level set segmentation for improved white/gray matter separation. This level set segmentation is a 3D and multiphase adaptation of a 2D method intended for use on images with the types of intensity Inhomogeneities found in MR images.
The initial tissue maps required to determine spatial priors for the one-year-old atlas were created by manually cleaning the results of an adult atlas and the automated pipeline. Additional tissue maps were incrementally added until the spatial priors were sufficiently representative. The neonate atlas was similarly created, starting with the one-year-old atlas.

Esta pesquisa aborda a relação entre a arquiteta iraquiana-britânica Zaha Hadid e alguns artistas da Vanguarda Russa. Hadid é mundialmente reconhecida por seus trabalhos na área da arquitetura, urbanismo e design, pelos quais recebeu diversos prêmios durante sua carreira. A arquiteta estudou na Architectural Association e conheceu obras de Kazimir Malevich por meio de seus professores Rem Koolhaas e Elia Zenghelis. Hadid iniciou uma conexão criativa com o projeto Malevich’s Tektonik (1976-77), um trabalho que transportou uma obra de Malevich para o contexto arquitetônico de Londres. A partir deste projeto, a inspiração pelo artista começou a ser potencializada e demonstrada em seu pensamento criativo. Também foram inspirações para a arquiteta os artistas: Moholy-Nagy, El Lissitzky e Naum Gabo. Hadid utilizava desenhos e pinturas de características abstratas semelhantes às obras destes artistas em sua produção arquitetônica. Sendo assim, o objetivo desta dissertação é realizar uma interlocução entre os pensamentos criativos da arquiteta e dos quatro artistas que fizeram parte da Vanguarda Russa. Visto que o fazer arquitetônico de Hadid se realizava em paralelo a um fazer artístico (pinturas), utilizaremos para atingir o objetivo desta pesquisa uma montagem de imagens inspirada em Aby Warburg – historiador de arte alemão. Warburg desenvolveu o Atlas Mnemosyne nos anos de 1920 em Hamburgo, Alemanha. Ele realizou este trabalho para entender como o período da Antiguidade “sobreviveu” no Renascimento. Mnemosyne foi uma montagem com imagens de períodos temporais diferentes que permite visualizar as intricações e relações entre elas. Realizamos uma montagem nominada “Hadid-Vanguarda” com imagens de obras dos quatro artistas e do processo criativo de quatro projetos da arquiteta. Os projetos são: o clube de lazer The Peak, o corpo de bombeiros Vitra Fire Station, o terminal de trem e ônibus Hoenheim-Nord Terminus and Car Park e o Museu de Arte Contemporânea MAXXI. Após as análises das pranchas da montagem, identificou-se três categorias teóricovisuais nominadas por “A Diagonal”, “A Vista Aérea” e “As Camadas”. Cada categoria compete a elementos que aparecem em ambos os pensamentos criativos de Hadid e da Vanguarda Russa. Sendo assim, considera-se que o contato com os artistas russos fez a arquiteta transcender os limites da criação convencional de projetos.
This thesis studies the relationship between the Iraqi-British architect Zaha Hadid and some artists of the Russian Avant-Garde. Hadid is widely recognized for her work in architecture, town planning and design, for which she received various awards throughout her career. During her time as a student at the Architectural Association School in London, she became familiarized with Kazimir Malevich’s works through professors Rem Koolhaas and Elia Zenghelis. Hadid then initiated a creative connection with arts, and in Malevich's Tektonik (1976-77), she transported Malevich’s work of art to the London’s architectural context. After this project, Malevich’s influence on her work became more evident, with some aspects surfacing in her creative process. Artists such as Moholy-Nagy, El Lissitzky and Naum Gabo also corroborated to her unique creative process. As she used drawings and paintings with abstract features similar to the works of these artists in her architectonic production. Therefore, the goal of this dissertation is to perform an interlocution between the architect’s creative process and the four artists who were part of the Russian Avant-Guarde. Since Hadid’s architectural rendering happened in parallel to her artistic work (i.e., paintings), we will use the Atlas Mnemosyne, a montage of images by Aby Warburg, to achieve the objective of this project. Warburg an art historian developed the Atlas Mnemosyne in the 1920s in Hamburg, Germany. He performed this work to understand how the period of Antiquity "survived" in the Renaissance. Mnemosyne was a montage with images of different time periods that allows visualizing relations between them. We realized a montage named "Hadid-Vanguarda" with images of works by the four artists and the creative process of four architect's projects. The Peak, a leisure club; Vitra Fire Station; Hoenheim-Nord Terminus and Car Park and MAXXI, a museum of contemporary arts are the selected projects. After the montage’s analysis, we identified three theoretical-visual categories nominated "The Diagonal", "The Aerial View" and "The Layers". Each category competes in elements that appear in both creative thoughts - Hadid and the Russian Vanguard. Therefore, we regarded that contact with Russians artists did Hadid transcend the boundaries in the conventional creation of projects.

Full textAbstract:
Among the various remote sensing methods that can be used to map forest areas, the K Nearest Neighbor (KNN) supervised classification method is becoming increasingly popular for creating forest inventories in some countries. In this study, the utility of the KNN algorithm is evaluated for forest/non-forest/water stratification. Antalya is selected as the study area. The data used are composed of Landsat TM and Landsat ETM satellite images, acquired in 1987 and 2002, respectively, SRTM 90 meters digital elevation model (DEM) and land use data from the year 2003. The accuracies of different modifications of the KNN algorithm are evaluated using Leave One Out, which is a special case of K-fold cross-validation, and traditional accuracy assessment using error matrices. The best parameters are found to be Euclidean distance metric, inverse distance weighting, and k equal to 14, while using bands 4, 3 and 2. With these parameters, the cross-validation error is 0.009174, and the overall accuracy is around 86%. The results are compared with those from the Maximum Likelihood algorithm. KNN results are found to be accurate enough for practical applicability of this method for mapping forest areas.

Full textAbstract:
Polygon-based classification applied on the unitemporal SPOT4 XS, SPOT5 XS, IKONOS XS, QuickBird XS and QuickBird Pansharpaned (PS) images is described. The study site is an agricultural area located near Karacabey, Turkey covering an area of about 95 km2. The objective was to assess the effect of the spatial resolution on the polygon-based classification of agricultural crops. Both the post-polygon and pre-polygon classifications were carried out. In the post-polygon classification, first, the images were classified on per-pixel basis through a Maximum Likelihood classifier. Then, for each field, the model class was computed and the field was assigned the label of the model class. In the pre-polygon classification, first, the mean values were calculated for each field. Then, the per-pixel Maximum Likelihood Classification was carried out using the mean bands.
The post-polygon classification of the SPOT4 XS and SPOT5 XS images produced an overall accuracy of 76,1% and 81,4%, respectively. The IKONOS XS image provided the highest overall accuracy of 88,6%. On the other hand, the QuickBird XS and QuickBird PS images provided the overall accuracies of 83,7% and 85,8%, respectively. For the pre-polygon classification, the overall accuracies of the SPOT4 XS and SPOT5 XS images were computed to be 65,2% and 69,8%, respectively. Similar to the post-polygon classification, the IKONOS image provided the highest overall accuracy of 81,8% while the SPOT5 XS image revealed slightly better results than the SPOT4 XS image. The overall accuracies of the QuickBird XS and PS images were found to be 78,6% and 82,1%, respectively.

Full textAbstract:
The present study inquires into the problematization of attention in the reception and distribution of photography in 19th-century Sweden. It investigates how photography’s alleged abundance of detail and indiscriminate reproduction became a problem in the reception of the medium. The problem became urgent when photographs were put to use by established discourses; specifically, when used in printed publications meant for a public. The thesis therefore argues that the problem of attention had a profound influence on how printed photographic or photographically illustrated editions (photo-texts) were modelled and arranged. For this purpose, the study affirms a particular focus on attention practices: the various ways in which the printed editions aim to regulate the reader’s attention before the supposedly distractive image. Specifically, the thesis focuses on how texts in these printed editions are arranged or juxtaposed in relation to the image, how they speak of and to the images, what values they reflect, and what effects they could be said to produce. Consequently, the present study is more than an investigation of a problem; it is also an inquiry into the various attempts to overcome this problem. The problem and its responsive practices will have different characteristics in the various contexts of individual discourses. Therefore, the study situates the problem of attention in four prominent genres of 19th-century photography: the topographical albums of photographic views, art books with photographic reproductions, the scientific atlas, and the photographically illustrated travelogue. These genres and forms of publication, as well as the discourses of attention relating to them, are discussed in separate chapters. Every chapter departs from a specific Swedish photographic edition from the nineteenth-century. In sum, the thesis aims – with its focus on the problematization of attention – at giving a new historical perspective on the emergent relation between photography and the printed word.

Un dels àmbits de la llengua on la variació dialectal es manifesta d’una manera més marcadament multiforme és el de la morfologia verbal. Antoni M. Alcover, considerat el fundador de la dialectologia a Catalunya, desenvolupà a començaments de segle el projecte que, sota el títol "Estudi especial de la conjugació", donava a conèixer el variat polimorfisme que presentaven les realitzacions verbals a tot el domini lingüístic català. Aquests resultats es plasmaren a finals deis anys vint i a principis deis trenta en la publicació de "La flexió verbal en els dialectes catalans".
Les dades recollides en aquest compendi constitueixen un reflex real de l’estat de la morfología verbal del català en un àmbit temporal, que s’estén del 1906 al 1928, i en un àmbit espacial, que es concreta en cent quaranta-nou localitats de sis àrees dialectals: el pirinenc oriental (que correspon grosso modo a l'actual rossellonès i a una part del català septentrional de transició), el català oriental, el català occidental, el valencià, el balear i l’alguerès.
Fins ara, algunes d’aquestes dades han estat utilitzades en treballs específics per il·lustrar la conjugació d’un verb en una zona geogràfica determinada o per constatar la variació que una forma verbal pot experimentar segons l'àrea dialectal on es realitzi. Tanmateix, els materials de "La flexió verbal en els dialectes catalans" mai no han estat estudiats globalment ni comparativament des d’un punt de vista sincrònic i, menys, des d’una perspectiva interdialectal. La descripció que es desenvolupará en aquest treball permetrà de contrastar les realitzacions subjacents deis segments morfològics que conformen cinc verbs que, per les seves característiques, esdevenen els representants regulars de les diverses varietats dialectals.
En definitiva, l’objectiu general d’aquesta tesi és dur a terme una anàlisi de l’estructura del verb català a començaments de segle i de la variació morfològica que pot presentar aquesta estructura en els diversos dominis dialectals. L’estudi se centra en la flexió de cinc verbs que s’han establert com a models regulars. Els paradigmes s’han obtingut a partir de les dades incloses en el recull d’Alcover, que incorpora la conjugació completa de setanta-quatre verbs que van ser enquestats durant els tres primers decennis d’aquest segle.

Multiple Sclerosis (MS) is an inflammatory demyelinating (that is, with myelin loss) disease of the Central Nervous System (CNS). It is considered an autoimmune disease in which the immune system wrongly recognizes the myelin sheath of the CNS as an external element and attacks it, resulting in inflammation and scarring (sclerosis) of multiple areas of CNS’s white matter. Multi-contrast magnetic resonance imaging (MRI) has been successfully used in diagnosing and monitoring MS due to its excellent properties such as high resolution and good differentiation between soft tissues. Nowadays, the preferred method to segment MS lesions is the manual segmentation, which is done by specialists with limited help of a computer. However, this approach is tiresome, expensive and prone to error due to inter- and intra-variability between observers caused by low contrast on lesion edges. The challenge in automatic detection and segmentation of MS lesions in MR images is related to the variability of size and location of lesions, low contrast due to partial volume effect and the high range of forms that lesions can take depending on the stage of the disease. Recently, many researchers have turned their efforts into developing techniques that aim to accurately measure volumes of brain tissues and MS lesions, and also to reduce the amount of time spent on image analysis. In this context, this project proposes the study and development of an automatic computational technique based on an outlier detection approach, Student’s t-distribution finite mixture models and probabilistic atlases to segment and measure MS lesions volumes in MR images.
Esclerose Múltipla (EM) é uma doença inflamatória e desmielinizante (isto é, com perda de mielina) do sistema nervoso central (SNC). É considerada uma doença autoimune a qual o sistema imunológico reconhece erroneamente a bainha de mielina do SNC como um elemento externo e então a ataca, resultando em inflamação e formação de cicatrizes gliais (escleroses) em múltiplas áreas da substância branca do SNC. O imageamento multi- contraste por ressonância magnética (RM) tem sido usado clinicamente com muito sucesso para o diagnóstico e monitoramento da EM devido às suas excelentes propriedades como alta resolução e boa diferenciação de tecidos moles. Atualmente, o método utilizado para a segmentação de lesões de EM é o delineamento manual em imagens 3D de RM, o qual é realizado por especialistas com ajuda limitada do computador. Entretanto, tal procedimento é custoso e propenso à variabilidade inter e intraobservadores devido ao baixo contraste das bordas das lesões. A grande dificuldade na detecção e segmentação automáticas das le- sões de EM em imagens de RM está associada às suas variações no tamanho e localização, baixo contraste decorrente do efeito de volume parcial e o amplo espectro de aparências (realçadas, não-realçadas, black-holes) que elas podem ter, dependendo do estado evolutivo da doença. Atualmente, vários pesquisadores têm voltado seus esforços para o desenvol- vimento de técnicas que visam diminuir o tempo gasto na análise das imagens e medir, de maneira mais precisa, o volume dos tecidos cerebrais e das lesões de EM. Nesse contexto, este projeto propõe o estudo e o desenvolvimento de uma técnica computacional automá- tica, baseada na abordagem de detecção de outliers e usando modelos de misturas finitas de distribuições t-Student e atlas probabilísticos para a segmentação e medição do volume de lesões de EM em imagens de RM.

Full textAbstract:
In the education of Geography, the School Cartography is of basic importance, therefore the people, when she/he
are alphabetized cartographyly, he/she has the capacity to interpret maps, images and other geographic
representations. In this way, the didatic materials foreseen by the pedagogical conceptions are elaborated in
analogical electronic digital means to subsidize the understanding of the local space. The Municipal Electronic
Atlas come with a proposal innovative, therefore they motivate and invite learners and teachers to the practice of relating the space representations and also of providing the study of the lived space, sometimes building it, sometimes not building it through the observation of the socio-ambient elements, making with that the people
wakes up bigger interest for the study of the geographic space. Inside this preamble, the present research has as
main purpose to approach the importance of the study of the local space in the perspective of school cartography,
in this case, Restinga Sêca county of RS through the elaboration of these atlases. The Atlas considered, in its
conception, it possesses partial interaction with the user and it presents resources of multimedia with texts,
images and animation. It allows to the student or user the manipulation of a set of maps, with the possibility to
select the socio-economic subject or subjects that they desire to visualize, being able to combine predefined
subjects and to configure a map. In this study, it structuralized itself of according to the municipal approach considering whole area of the county and, in specific the urban area, it chose twelve groups of socio-economics variables for the elaboration of the urban thematic maps, in both approaches was considered as space unit the census sector. Methodologily, it was followed the proposal of Brazilian Institute of Geography and Statistics for the definition of the variables according to Demographic Census 2000. In this way, a resource to verify if the map is fulfilling its function of communicator is the elaboration and application of tests with the users to verify the acceptability of it, in order to validate it as map pertaining to the Eletronic Atlas. The pilot test of these maps consist of many tests of isolated maps or of sets with the intention to become legitimate the maps that compose the Eletronic Socio-Economic of Restinga Sêca and to verify the learning easiness. The pilot test should be applied as a test to the public target: detainer and user of these Atlas. In this direction, it chose the five serie of high school due to be the period of training that the child starts the study of the cartography and studies of Restinga Sêca county. As results, it was observed that the rightness indices of peoples had been over of 60% practically at all the modules. In some cases, the index of rightnesss of people was low and the maps had been reworked and adapted for a better understanding. This facilitates the learning. Many maps had taken care of the goals and it was not necessary great alterations for their use. Ahead of the results, it considered the Atlas a didactic material and a resource of learning in digital means propitious digital for the use at school environment for the study of this county.No ensino da Geografia, a Cartografia Escolar é de fundamental importância, pois o aluno, quando alfabetizado cartograficamente, tem a capacidade de interpretar mapas, imagens e outras representações geográficas. Desse modo, os materiais didáticos previstos pelas concepções pedagógicas são elaborados em meio analógico, eletrônico e digital para subsidiar a compreensão do espaço local. Os Atlas Eletrônicos Municipais vêm com uma proposta inovadora, pois motivam e convidam os discentes e docentes à prática de relacionar as representações espaciais e, também, oportunizam o estudo do espaço vivido, ora construindo-o, ora desconstruindo-o através da observação dos elementos socioambientais, fazendo com que o aluno desperte maior interesse pelo estudo do espaço geográfico. Dentro deste preâmbulo, a presente pesquisa tem como finalidade precípua abordar a importância do estudo do espaço local na perspectiva da cartografia escolar, neste caso o município de Restinga Sêca, RS, através da elaboração deste Atlas. O Atlas proposto, em sua concepção, possui interação parcial com o usuário e apresenta recursos de multimídia com textos, imagens e animações. Permite ao aluno ou usuário a manipulação de um conjunto de mapas, com a possibilidade de selecionar o tema ou os temas socioeconômicos que deseja visualizar, podendo combinar temas pré-definidos e configurar um mapa. Este estudo estruturou-se a partir de uma abordagem municipal e considerou-se toda área do Município e, em específico a área urbana, selecionou-se doze grupos de variáveis socioeconômicas para a elaboração dos mapas temáticos urbanos. Em ambas abordagens, considerou-se como unidade espacial o setor censitário. Metodologicamente, seguiu-se a proposta do Instituto Brasileiro de Geografia e Estatística para a definição das variáveis conforme o Censo Demográfico 2000. Desta maneira, um recurso para verificar se o mapa está cumprindo sua função de comunicador é a elaboração e aplicação de testes com os usuários para verificar a aceitabilidade dele, a fim de validá-lo como mapa pertencente ao Atlas Eletrônico. O teste piloto destes mapas consiste de muitos testes de mapas isolados ou em conjuntos com o intuito de tornar legítimos os mapas que compõem o Atlas Eletrônico e Socioeconômico de Restinga Sêca e verificar a facilidade de aprendizagem. O teste piloto deve ser aplicado como um teste ao público alvo: o detentor e o usuário deste Atlas. Neste sentido, selecionou-se a 5ª série do Ensino Fundamental, devido a ser o estágio em que a criança inicia o estudo da cartografia e estuda o município de Restinga Sêca. Como resultados, observou-se que os índices de acertos dos alunos foram acima de 60% praticamente em todos os módulos. Em alguns casos, o índice de acertos dos alunos foi baixo, e os mapas foram retrabalhados e adaptados para uma melhor compreensão, facilitando o aprendizado. Muitos mapas atenderam ao objetivo e não foram necessárias grandes alterações para a sua utilização. Diante dos resultados, considerou-se o Atlas um material didático e um recurso de aprendizagem em meio digital propício para a utilização no ambiente escolar para o estudo do Município.

Full textAbstract:
Nell’attualità l’agricoltura urbana sperimenta una grande espansione che, iniziata durante gli anni Settanta, si è accelerata vertiginosamente a partire dall’inizio del XXI secolo. Le nuove dinamiche emergenti tra amministratori e cittadini in un mondo fortemente urbanizzato, vedono la città come scenario privilegiato di sperimentazione socio-spaziale e la recente inclusione dell’agricoltura nelle aree urbane costituisce una manifestazione molto significativa dei paradigmi – come la sostenibilità e la democrazia partecipata – che guidano tanto le politiche istituzionali quanto le iniziative di cittadinanza. In questa tesi presentiamo l’agricoltura urbana come strumento di analisi delle nuove relazioni tra istituzioni e cittadini che si svolgono nelle città europee contemporanee, prendendo come riferimento teorico le relazioni di potere nella “città delle reti” secondo Manuel Castells, il concetto di “diritto alla città” e la distinzione tra la Città e l’Urbano elaborati da Henri Lefebvre, nelle re-interpretazioni che recentemente hanno sviluppato David Harvey e Manuel Delgado. Alla luce di questo inquadramento concettuale, vengono presentate le caratteristiche storiche e attuali dell’agricoltura urbana a Barcellona dove si possono osservare diverse dinamiche nelle relazioni tra istituzioni e cittadini intorno agli orti urbani: occupazione informale di spazi urbani (più o meno tollerata), istituzionalizzazione di orti “informali”, creazione e gestione di orti e aree produttive in ambito urbano da parte degli enti locali e, infine, processi di pianificazione partecipata in cui la agricoltura assume un ruolo centrale tra le attività urbane.Nowadays urban agriculture experiences a large expansion that began in the seventies and has accelerated dramatically since the beginning of the XXI century. The new emerging dynamics between administrators and citizens in a highly urbanized world, make the city a privileged scene of socio-spatial experimentation and the recent inclusion of agriculture in urban areas constitutes a very significant event of the paradigms - such as sustainability and participatory democracy - that guide both the institutional policies and the citizenship initiatives. In this thesis we present urban agriculture as a tool for analyzing the new relationships between institutions and citizens that take place in contemporary European cities, taking as theoretical reference the power relations in the "city of nets" according to Manuel Castells, the concept of "law the city "and the distinction between the City and the Urban developed by Henri Lefebvre, in reinterpretations that have recently developed David Harvey and Manuel Delgado. In light of this conceptual framework, the atlas presents the historical and current characteristics of urban agriculture in Barcelona where different trends can be found in relations between institutions and citizens around the urban gardens: informal squattering in urban areas (more or less tolerated), institutionalization of "informal gardens", creation and management of productive gardens in urban areas by local authorities and, finally, participatory planning processes in which agriculture plays a central role among the urban activities.

Full textAbstract:
Este trabajo se presenta como una herramienta eficaz para facilitar la identificación de los restos de fauna arqueológica. Se trata de un soporte para el análisis del material arqueofaunístico, realizado desde la perspectiva arqueológica.
Cuando nos enfrentamos al análisis taxonómico de la fauna arqueológica, a los arqueólogos/as nos aparecen una serie de problemas metodológicos, a parte de la tarea del análisis en si mismo: nos remitimos a una colección de referencia que, por muy variada que sea, puede resultar incompleta en muchas ocasiones. También contamos con diferentes atlas osteológicos – arqueológicos, veterinarios, paleontológicos – con los cuales hemos elaborado nuestra propia bibliografía de referencia. Una especie hand made funcional, que mimamos con cariño y que actualizamos constantemente con aportaciones, propias o no.
Así, coleccionamos un dossier muy práctico, pero al que siempre le falta algún dato.
Las nuevas tecnologías han proporcionado herramientas suficientes para mejorar nuestro altas hand made: La fotografía digital permite tomar imágenes mucho más precisas y ampliadas de los caracteres morfológicos de un resto determinado de fauna y establecer referencias más exactas que un dibujo.
Las posibilidades de la informática aumentaron nuestras expectativas: nos planteamos ir más allá de los trabajos realizados hasta el momento. Nos propusimos elaborar un nuevo atlas, interactivo, funcional y, lo que es más importante, abierto a toda la comunidad arqueológica.
Nos exigimos trabajar con la tecnología que disponíamos, aunque todos/as conocíamos otras alternativas mucho más espectaculares, pero fuera de nuestro alcance, sobre todo económico y que frecuentemente se quedan en un simple experimento del uso de esas nuevas tecnologias.
Éste altas tendría que tener una característica básica: ser útil para la comunidad arqueológica, fácil de actualizar y transportable a cualquier punto del planeta. Esto implicaba que lo había de concebir una persona arqueóloga conocedora del trabajo que implica la determinación taxonómica de la fauna arqueológica.
Bajo esta perspectiva iniciamos la elaboración de este trabajo. Muchas veces tuvimos que volver sobre nuestros pasos, abandonar una u otra técnica, “inventar” soportes para poder tomar las imágenes deseadas o exigir a algunos programas informáticos más de lo realmente que podían ofrecer.
Presentamos este atlas, no sin tener en cuenta que se trata principalmente de una herramienta útil y ampliable. Pretendemos facilitar la tarea de identificar los restos de fauna arqueológica, no la de realizar, sin más experiencia, un análisis taxonómico completo. Al mismo tiempo explicamos cómo se puede ampliar y aplicar la misma sistemática a otros sistemas y objetos de clasificación.
La práctica en el laboratorio, en la excavación y con ejemplares de referencia es básica para una correcta identificación: La decisión es del profesional, todavía. La máquina puede ayudar, extraordinariamente.
Pero el cerebro humano toma la decisión final del resultado. De momento.This project is an efficient tool for the identification of archaeological faunal remains. It is a support for the analysis of the archaeofaunistic material. An analysis made from an archaeological perspective. When facing the taxonomic analysis of archaeological fauna, several methodological problems, a part from the analysis work itself, come to archaeologists’ minds, as for instance: a reference collection with a great variety of specimens but which might be incomplete, as it happens several times. We also use different osteologic atlas – archaeological, veterinarian, palaeontological – which we have elaborated our own reference bibliography with. One hand made functional specimen which we take good care of and update constantly with our own or others contributions. That way, we can collect a very useful dossier, but which always lacks some information. New technologies have provided enough tools to improve our hand made atlas: digital photography makes possible to take more precise and enlarged images of morphological characters from a specific fauna remain, and it also allows a more precise establishment of references than the ones obtained in drawings. The range of possibilities that computer science gives increased our expectations: we considered going further in the studies and work carried out until the moment. We set out to elaborate a new atlas: interactive, functional, and the most important thing, open to the whole archaeological community. We forced ourselves to work with the technology that we had at our disposal, even though we were all aware of other more impressive alternatives which were, though, out of our reach, mainly due to economical issues. And these alternatives usually end up being just an experiment of the use of these new technologies. The atlas must contain an essential characteristic: to be useful for the archaeological community, easy to upload and transportable anywhere in the planet. This characteristic implied that the person in charge of its creation had to be an archaeologist aware of the work involving taxonomic determination of archaeological fauna. According to this perspective we started the elaboration of this project. We had to retrace our steps, give up the use of this or that technique, “invent” supports to be able to get the desired images, or expect too much from some computing software. We present this atlas, not without taking into account the fact that it is a useful tool that can be increased. Our aim is to facilitate the identification of archaeological faunal remains, and not the realization, without further experience, of a complete taxonomic analysis. At the same time, we explain how can the atlas be increased and how to use the same patterns in other systems and classification objects. The work in the laboratory, in the excavation and the use of reference samples is essential for a right identification: the decision is still taken by the professional. Machines can help, in an extraordinary way. But the human brain takes the last decision in the result. For the moment.

Seit über 150 Jahren erscheinen in den statistischen Institutionen thematische Atlanten – bis heute über 2500 Werke. Als «Reiseführer» durch Gesellschaften erzählen sie spannende und vielfältige Geschichten über den Staat, die Menschen und deren Zusammenleben. Gerade im Kontext der Informationsgesellschaft nehmen solche Atlaswerke wieder sprunghaft zu und sprechen dabei ein außerordentlich breites Nutzerspektrum aus allen Berufskreisen an.
Ziel der vorliegenden Dissertation war es, durch theoretische und empirische Methoden das Wesen, die geschichtliche Entwicklung und die prägenden Merkmale des «Statistischen Atlas» eingehend zu untersuchen und damit Forschungslücken in der Thematischen Kartographie, der Atlaskartographie und der Statistik zu schließen. Mit Hilfe einer neu entwickelten Definition sowie einer aktuellen Atlasklassifikation können statistische Atlanten eindeutig bestimmt und von verwandten Atlastypen – etwa dem National-, dem Regional- oder dem Planungsatlas – im Hinblick auf die korrekte Einordnung in Bibliographien und Atlassammlungen abgegrenzt werden.
Weiterhin sind die gewonnenen Erkenntnisse für die Herausgeber neuer Atlaswerke und Atlasplattformen von großem Nutzen. Sie können in der Praxis als redaktionelle Grundlagen im Sinne eines Leitfadens zur erfolgreichen Produktion neuer, nutzergerechter Atlanten eingesetzt werden. Im beigefügten Atlasverzeichnis sind zudem 735 statistische Atlanten mit bibliographischen Angaben dargestellt.

On Ericsson Ltd in Borås a wireless communication system called MINI-LINK™ is produced. In order to sell their product with the best possible quality guaranty, there is a signal processing circuit called ATLAS implemented in the system. This circuit would eventually be useful in the production and for the repairs of the radio units. Our commission was to examine the possibility for this use. In order to read out various register in Atlas’s, a program which has these possibilities is needed and such program was already in use producing the units on which the ATLAS circuit is assembled. In the test which was done during readout of the registers that seemed relevant, it emerged that ATLAS does not give any information about the signals characteristic when it enters the modem unit, but first after all adjustments have been done. Because of this fact it seemed impossible to use ATLAS in some bigger extent as it works today, when it is fundamentally not done in order to be used as an instrument, in order to evaluate the property of signals coming from other units. The following question was about what could be done in a new generation and a thought was to scan existing internal control signals in order to receive more information about how much ATLAS is working to correct errors in the received signals.Uppsatsnivå: C

Esta dissertação procura construir uma trajetória que atravesse pontos concernentes à enunciação em quatro livros de André Gide: La Symphonie pastorale, La Porte étroite, Les Faux-monnayeurs e Le Prométhée Mal Enchaîné. A enunciação será aqui pensada junto do artigo de Émile Benveniste intitulado Da subjetividade na linguagem, em que o autor propõe que a subjetividade não seja vista como a substância psíquica sujeito, mas como um posicionamento tomado diante da língua. Não existiria, em outras palavras, sujeito anterior às coordenadas linguísticas que indicam o seu lugar de habitação donde a tentativa de construção, em minha dissertação, de um espaço enunciativo em Gide. Levando em conta as publicações mencionadas, dividi as questões enunciativas em duas principais regiões: a primeira será lida do ponto de vista do pronome eu (La Symphonie pastorale e La Porte étroite) e a segunda, escrita sobretudo com o emprego da dita terceira pessoa (Les Faux-monnayeurs e Le Prométhée Mal Enchaîné), será pensada como, ela também, uma possibilidade enunciativa isto é, como uma possibilidade de presença a partir da emergência do conector mas. O foco na enunciação designa aqui um esforço em deslocar o olhar de determinados jargões que habitam os estudos literários (como o autor ou o narrador), de modo a fundar um campo em que a enunciação possa ser pensada em suas próprias condições de emergência. Ademais, pensar essas condições é também e sobretudo não ignorar o ponto de vista crítico, mas assumi-lo como parte integrante do espaço enunciativo gideano. Assim, junto da reflexão em torno da enunciação em Gide, elabora-se uma tentativa integrada de reflexão de minhas próprias condições para enunciar qualquer coisa que seja dentro desta dissertação.This dissertation aims at building a path that would cross some points concerning the enunciation in four of André Gides books: La Symphonie pastorale, La Porte étroite, Les Faux-monnayeurs e Le Prométhée Mal Enchaîné. The enunciation will be thought with Émile Benvenistes article Subjectivity in language, in which the author proposes that subjectivity would rather be seen as position taken towards language than as a psychical subject. In other words, there is not a possible subject preceding the language coordinates that indicate its dwelling place from this point, I attempt to build, in this dissertation, an enunciative space in Gide. Taking into consideration the referred publications, I divided the enunciative issues in two main regions: the first will be read under the perspective of the I (La Symphonie pastorale and La Porte étroite) and the second, written mostly with the use of the third person (Les Faux-monnayeurs and Le Prométhée Mal Enchaîné), will be thought such as an enunciative possibility which means a possibility of presence from the emergence of the connector but. The focus on enunciation designates in this text an effort to dislocate the point of view of some jargons occupying today the literary studies (such as author or narrator) in order to establish a field in which the enunciation can be thought in its own emergence conditions. Moreover, thinking this conditions is also and above all not to overlook the critics point of view, but to assume it as an integral part of Gides enunciative space. So with the reflection on Gide, I elaborate an integrated attempt of thinking about my own conditions of enunciating anything within this dissertation.

O crescente grau de complexidade de sistemas de análise e representação de imagens, o uso de conhecimentos proporcionalmente complexos torna-se cada vez mais exigidos. Na área médica, onde as imagens possuem qualidade e conteúdos bastante diferentes, essas exigências dos sistemas de análise e representação de imagens tornam-se bem mais necessários. Esta necessidade exige o desenvolvimento de ferramentas computacionais robustas e confiáveis.Este trabalho apresenta o desenvolvimento de um atlas cerebral digital, deformável e adaptável ao cérebro específico de cada paciente. Baseando-se no modelo definido por Talairach, este atlas digital foi modelado a partir de uma variação da estrutura de armazenamento de dados tridimensional em árvore, conhecida como octree. Esta ferramenta faz o mapeamento funcional e anatômico de áreas cerebrais, identifica a relação dos quadrantes com a área de Brodman e associa as áreas cerebrais com suas funções, baseando-se no "Atlas de Talairach". Este sistema tem como objetivo auxiliar a identificação e a localização automatizada de áreas cerebrais e áreas funcionais em imagens obtidas através de Tomografia Computadorizada (TC) e Ressonância Magnética (RM), correlacionando dados da imagem do paciente com as funções possivelmente afetadas por lesões encontradas, conforme sua localização

Full textAbstract:
The use and optimisation of integration grid techniques to generate next-to-leading order predictions of jet cross-sections, independent of parton distribution functions, was investigated. Such methods were found to provide an accurate approximation to a standard Monte-Carlo simulation (within 1%) and enable collider data to be readily included in global PDF fitting procedures. However, the benefit of including inclusive-jet cross-section data from ATLAS in global fits is only significant if the jet energy scale (JES) can be constrained to ~1% at high pT. Uncertainties in the theoretical prediction of the inclusive-jet cross-section such as PDFs and fixed-order (scale) uncertainties were studied and compared with experimental errors arising from jet energy resolution and absolute scale. These uncertainties were then considered in the context of a quark compositeness search where a sensitivity to a compositeness scale of Lambda<10TeV can be achieved with 10 inverse femtobarns of data, if the jet energy scale can be constrained to ~1%. An analysis using dijet angular distributions found a similar sensitivity without the dependence on the jet energy scale. A potential method of evaluating the stability of the jet energy scale out to high pT by `bootstrapping' the calibration at low pT by the use of multi-jet events was also investigated. This suggests that a calorimeter non-linearity can be detected for jets with pT>500GeV at ~1.5%/500GeV (i.e. a 1.5% change in JES over 500GeV in pT). An investigation of inner-detector commissioning issues associated with the ATLAS Semiconductor Tracker (SCT), including a review of `noisy' modules on the SCT Barrel (from May 2007) was carried out. In addition a tool for DCS monitoring within the online monitoring framework was developed and tested during the M5 and M6 commissioning weeks. Finally, a method of assessing the track reconstruction efficiency by track-insertion was considered for the particular case of minimum bias events.

Full textAbstract:
"atlante" est un terme d'origine grecque attribue a une figure humaine de support utilisee des l'antiquite dans le decor architectural. A cause de son rapport iconographique a la charge qui la surmonte, la figure se refere au mythe grec d'atlas, porteur de la voute celeste. Ainsi l'atlante recoit-il une signification cosmologique. L'atlante, comme l'etait atlas, devient dans les programmes iconographiques romans un lien essentiel entre le haut et le bas, le celeste et le terrestre. Il constitue un point-cle dans la lecture des ensembles romans, articulant les rapports et les tensions entre differents domaines symboliques iconographiques et architectoniques. D'une part l'atlante, qui participe activement a la structure architecturale, souligne par son axe vertical la fonction tectonique de la sculpture. D'autre part, il lie des ensembles iconographiques distincts. L'atlante est defini par des attitudes differentes. Le type de l'atlante debout qui semble s'elever vers le faix, et le type accroupi, courbe et prisonnier de la charge superieure, expriment deux idees differentes, voire opposees, mais qui sous-tendent un meme concept moral et spirituel. Ce que l'atlante signifie au-dela de son comportement physique, c'est l'image de la condition humaine, ce sont les voies morales et ethiques du cheminement interieur et ascensionnel de l'homme. Plusieurs ensembles iconographiques -en france, en espagne, en italie et en suisse- sont examines du point de vue de la signification des deux comportements opposes de la figure de l'atlante. Un ca- talogue rassemblant tous les exemples romans trouves en france accompagne la these"atlante figure" was a designation given by the greeks to a human supporting figure used since antiquity in architectural decoration, and which through its iconographical relationship to its architectural burden refers to the greek myth of atlas supportin g heaven. Thus the atlante figure has a cosmological significance. In the romanesque iconographical programs the atlante figure becomes, just as atlas was, an essential link created between high and low, between the celestial and the terrestrial world. It articulates for the viewer the relations and tensions between various iconographical and architectonic symbolic worlds. On one hand the atlante figure by its vertical axis underlines the tectonic function of the sculpture in architecture. On the other hand it creates a link between different iconographical groups. The atlante-figure appears in different attitudes. The upright type which seemsto reach toward the load, and the crouching type, imprisoned by its upper load, express two very different, and even opposed images but which belong to the same moral and spiritual concept. The atlante-figure is, beyond its physical reality, the image of the human condition and of the moral and ethical quest of the human being. Several iconographical groups -in france, spain, italy and switzerland- are discussed to clarify the meaning of the two opposing attitudes of the atlante-figure. A catalogue with all the romanesque exemples found in france has been added at the end of this study

Full textAbstract:
Les atlases d'anatomie informatisé jouent un rôle important dans l'analyse d'images médicales. Cependant un atlas se réfère généralement à une image standard ou une moyenne d'image aussi appelé template, qui probablement représente bien d'une population observée, il ne suffit pas pour caractériser la population observée en détail. Un template doit être apprises conjointement avec la variabilité géométrique des formes représentées dans les observations. Ces deux quantités seront par la suite former l'atlas de la population correspondante. La variabilité géométrique est modélisée comme des déformations du template de sorte qu'il s'adapte aux observations. Dans la première partie du travail, nous fournissons un nouveau modèle statistique générative basée sur des templates déformables denses qui représente plusieurs types de tissus observés dans les images médicales. Notre atlas contient à la fois une estimation des templates probabiliste de chaque tissu (appelée classes) et la métrique de déformation. Nous utilisons un algorithme stochastique pour l'estimation de l'atlas probabilistes donné un ensemble de données. Cet atlas est ensuite utilisé pour la méthode de segmentation basée sur l'atlas pour segmenter les nouvelles images. Expériences sont montrées sur les images T1 du cerveau. Les analyses traditionnelles d'imagerie de résonance magnétique fonctionnelle utilisent peu d'informations anatomies. Le recalage des images vers un template est basé sur l'anatomie individuelle et ne tient pas compte des informations fonctionnelles, donc les activations détectées ne se limitent pas à la matière grise. Dans la deuxième partie du travail, on propose un modèle statistique pour estimer un atlas probabiliste de l'IRM fonctionnelle et T1 qui résume à la fois des informations anatomies et fonctionnelles et la variabilité géométrique de la population. Le recalage et la segmentation sont effectuées conjointement pendant l'estimation de l'atlas et l'activité fonctionnelle est limitée à la matière grise, augmenter la précision de l'atlas. Inférer l'abondance des protéines de l'intensité de peptides est l'étape clé dans la protéomique quantitative. La conclusion est nécessairement plus précis quand de nombreux peptides sont pris en compte pour une protéine donnée. Pourtant, l'information apportée par les peptides partagées par différentes protéines est souvent jeté. Dans la troisième partie du travail, nous proposons un système statistique basée sur une modèle hiérarchique à inclure cette information. Notre méthodologie, basée sur une analyse simultanée de tous les peptides quantifiés, gère les erreurs biologiques et techniques ainsi que l'effet des peptides. En outre, nous proposons une mise en œuvre pratique adapté à l'analyse de grandes bases de données. Par rapport à une méthode basée sur l'analyse d'une protéine à la fois (ce qui ne comprend pas les peptides partagés), notre méthodologie s'est révélée être beaucoup plus fiable pour estimer l'abondance de protéines et de tester les changements d'abondanceComputerized anatomical atlases play an important role in medical image analysis. While an atlas usually refers to a standard or mean image also called template, that presumably represents well a given population, it is not enough to characterize the observed population in detail. A template image should be learned jointly with the geometric variability of the shapes represented in the observations. These two quantities will in the sequel form the atlas of the corresponding population. The geometric variability is modelled as deformations of the template image so that it fits the observations. In the first part of the work, we provide a detailed analysis of a new generative statistical model based on dense deformable templates that represents several tissue types observed in medical images. Our atlas contains both an estimation of probability maps of each tissue (called class) and the deformation metric. We use a stochastic algorithm for the estimation of the probabilistic atlas given a dataset. This atlas is then used for atlas-based segmentation method to segment the new images. Experiments are shown on brain T1 MRI datasets. Traditional analyses of Functional Magnetic Resonance Imaging use little anatomical information. The registration of the images to a template is based on the individual anatomy and ignores functional information; subsequently detected activations are not confined to gray matter. In the second part of the work, we propose a statistical model to estimate a probabilistic atlas from functional and T1 MRIs that summarizes both anatomical and functional information and the geometric variability of the population. Registration and Segmentation are performed jointly along the atlas estimation and the functional activity is constrained to the gray matter, increasing the accuracy of the atlas. Inferring protein abundances from peptide intensities is the key step in quantitative proteomics. The inference is necessarily more accurate when many peptides are taken into account for a given protein. Yet, the information brought by the peptides shared by different proteins is commonly discarded. In the third part of the work, we propose a statistical framework based on a hierarchical modeling to include that information. Our methodology, based on a simultaneous analysis of all the quantified peptides, handles the biological and technical errors as well as the peptide effect. In addition, we propose a practical implementation suitable for analyzing large datasets. Compared to a method based on the analysis of one protein at a time (that does not include shared peptides), our methodology proved to be far more reliable for estimating protein abundances and testing abundance changes

Previous issue date: 2008Recursos hídricos em quantidade e qualidade satisfatórios são essenciais para o bem-estar de uma sociedade. A água é bem de consumo final ou intermediário para as atividades humanas, e com o aumento da intensidade e variedade de seu uso, ocorrem conflitos entre usuários. No sentido de se buscar tecnologias que possam auxiliar na minimização dos conflitos e da escassez hídrica, o uso da geoinformação é uma alternativa que possibilita uma visão macro do processo facilitando na construção de um modelo de gestão eficiente, permitindo uma economia de recursos financeiros e de tempo. Para tanto essa pesquisa propõe a construção de um Atlas Eletrônico Analítico que permita ao usuário consultar e gerar mapas interativamente, dando suporte ao planejamento dos recursos hídricos. A pesquisa apresenta a modelagem funcional do atlas, explicitando os fluxos de dados de entrada e saída e os processos desenvolvidos, define os recursos tecnológicos para a implementação do mesmo, apresenta os procedimentos para a aquisição, coleta e edição dos dados utilizados no atlas, concluindo com a análise e apresentação de alguns resultados alcançados. Um ponto importante no desenvolvimento do atlas é a possibilidade de gerar novas informações a partir dos dados originais, que pode ser feito através da combinação de diferentes feições cartográficas, e também da importação de novas informações para bancos de dados alfa-numérico e gráficos, gerando mapas temáticos atualizados. A validação do modelo foi feita na região da Bacia do Rio São Francisco que se encontra dentro do limite do Estado de Pernambuco, devido à representatividade dessa bacia hidrográfica para os recursos hídricos. Foram desenvolvidos com resultados, diversos mapas que ajudaram na caracterização hídrica e física da região estudada, como por exemplo o mapa dos principais sistemas adutores da região, mapa das barragens subterrânea e dessalinizadores por messoregião, mapa das barragens por volume de acumulação, mapa da precipitação pluviométrica média anual, entre outros
