Texto completo da fonteStudent of César Franck, Charles Bordes established himself as a musician outside the Conservatoire and the official institutions. From his integration with the “bande à Franck” to the founding of the Chanteurs de Saint-Gervais and the Schola cantorum, he formed a vast network of relationships among composers, interpreters, writers and music lovers, who would later describe him as a fervent architect of the French musical revival. This image overshadowed his contributions as a composer; his mélodies, however, still stimulate a remarkable interest. An examination of the history of their publication reveals the complexity of relationships within the musical publishing world at the end of the nineteenth-century and the nature of the posthumous reviewing work executed by his friend Pierre de Bréville. The analysis of the corpus shows the originality of the production, either about its literary aspects – Bordes was among the first artists to set the poetry of Paul Verlaine and Francis Jammes to music – or about his inspired musical language at the boundaries of academia from an harmonic point of view. Author of more than thirty-five songs for voice and piano, Bordes also tried his hand at the composition of orchestrated or “symphonic” songs like many of his contemporaries at the end of the century

Texto completo da fonteEstos últimos dos años de carrera, a través de las instancias ofrecidas por la universidad; el seminario de investigación, la práctica profesional, y el proyecto de titulación, encontré un espacio privilegiado para investigar, aprender y acercarme en forma más madura y profesional a problemáticas urbanas contingentes como: la expansión de los límites de la ciudad y la normativa de desarrollo condicionado que la ampara, la planificación urbana y su importancia en la conformación de barrios, y la concepción de la ciudad como un elemento más de la matriz geográfica que la contiene. Estas tres instancias académicas me han permitido reflexionar acerca del rol y la responsabilidad del arquitecto en la configuración de la ciudad, lo cual desde una visión optimista, transforma los problemas en oportunidades y la responsabildades en desafíos, pues si bien Santiago es considerada “una buena ciudad para vivir”1, bastaría tomar una micro en el centro por Santa Rosa hasta su terminal en la Pintana, para entender que en Santiago existen dos ciudades, y una gran deuda en cuanto a la consolidación de espacios públicos, áreas verdes y equipamiento, lo que sin duda determina el día a día de quienes la habitamos.
Viglialoro, Giuseppe. "Análisis matemático del equilibrio en estructuras de membrana con bordes rígidos y cables. Pasarelas: forma y pretensado". Doctoral thesis, Universitat Politècnica de Catalunya, 2007. http://hdl.handle.net/10803/6865.
Texto completo da fonteLa tesis se centra en el análisis matemático de las membranas portantes (abiertas y con bordes), con miras a extender sus aplicaciones en el campo de la ingeniería civil, concretamente a las pasarelas de peatones. Esto implica esfuerzos mayores, no sólo por los efectos de las cargas de uso de tales estructuras, sino porque requieren mayor pretensado para mantener la rigidez.
La tesis se centra en el análisis matemático de membranas a tracción en la fase de pretensado, en la que, como resultado de aplicar el pretensado a una forma potencial o virtual de la membrana, correspondiente a esfuerzos nulos, se llega ya a una forma real.
El problema de introducir y mantener el pretensado está relacionado con los bordes de la membrana, definidos por curvas en el espacio. Los mismos pueden tener curvatura o no tenerla (elementos rectos). Si los elementos de borde son rectos, para equilibrar el pretensado de la membrana, deben tener rigidez a flexión.
Entre los elementos de borde curvos, revisten notable importancia los cables a tracción, elementos sin rigidez a flexión cuya disposición permite distribuir los esfuerzos de tracción en toda la membrana.
Se aprecia, así, que ha de buscarse cierto equilibrio entre forma y pretensado tanto en el interior de la membrana como en su borde.
Matemáticamente, el planteamiento más general, y más complejo, corresponde al caso en que los elementos de borde son cables a tracción.
Lo dicho lleva a dos problemas de contorno.
El primero consiste en encontrar, una vez fijada la forma de membrana, los esfuerzos de pretensado que verifiquen el equilibrio (planteamiento directo) y el segundo en encontrar, una vez fijados los esfuerzos de tracción, la forma de la membrana que verifique el equilibrio (planteamiento dual).
Ambos problemas se complican sensiblemente en el caso en que el borde esté compuesto por cables a tracción.
El resultado principal del problema directo es que, en cualquier caso (esto es, independientemente de que el borde sea rígido o no), se obtiene un problema diferencial hiperbólico con condición de contorno de tipo Dirichlet.
Si a esto se le añade que, en el caso en que se consideren cables de borde éstos coinciden con las curvas características, el problema directo está en general mal definido.
El resultado principal del problema dual es que, en cualquier caso (esto es, independientemente de que el borde sea rígido o no) se obtiene un problema diferencial elíptico con condición de contorno de tipo Dirichlet, esto es un problema diferencial en general bien definido.
Siempre que no se consideren cables, el problema dual devuelve una única forma de membrana por cada distribución de esfuerzos de tracción (problema elíptico con condición de Dirichlet).
Al revés, el problema dual completo (con cables) tiene una formulación "no clásica" visto que, a largo del cable, su incógnita ha de verificar contemporáneamente dos condiciones: una de tipo Dirichlet y otra (no estándar) sobre las derivadas segundas de la forma de membrana.
En la tesis se describe un método numérico para el cálculo de la solución. Éste se basa en la definición de un "vector residual" que, al ser "minimizado", devuelve el valor nodal de la membrana a lo largo del cable.
Membranes are structures (without bending stiffness) identified with space surfaces with minimal thickness. They are approximated by geometrical surfaces and its stress tensor is defined by tension vectors in the tangent plane.
The PhD thesis is based on the mathematical analysis of membrane structures (opened and with boundaries) with the idea of applying them in Civil Engineering, more precisely to a new technology such as bridgefoots. It implies taking in account greater tensions, not only due to the loads that structures are subjected to, but because the same structures need more prestressed to preserve rigidity.
The report is based on mathematical analysis of tension membranes in the prestressed phase. In this phase, starting from a virtual shape for the membrane, with all tensions zeros, you obtain, due to the application of the prestressed, a real form.
The problem in introducing and preserving the prestressed is related to the boundaries of the membrane, defined by regular space curves. The boundaries can be curved or not (straight elements). If boundary elements are straight, to verify the equilibrium with the prestressed of membrane, they must have bending stiffness.
On the other hand, cables are very important curved boundary elements. They have no bending stiffness (work in tension, do not resist to compression) and its shape and placement is such that they can administer tensions all over the membrane.
In this way you can notice that is important looking for an equilibrium between shape and prestressed both in the interior of membrane and on its boundaries.
Mathematically the general approach, which is more difficult, concerns the case in which boundary elements are cables.
What has been said leads to two boundary problems.
The first one consists in finding, given the shape of the membrane, its prestressed stress tensor that verifies the equilibrium (direct approach). The second one concerns in finding, given the prestressed stress tensor of the membrane, its shape that verifies the equilibrium (dual approach).
If a boundary with tension cables is considered both problems make more difficult.
The principal result about the direct problem is that, in any case (that is, regardless of the kind of boundary used), a hyperbolic differential problem with Dirichlet boundary conditions is obtained.
Moreover if you consider that, in case that cables boundary elements are taken in account they are characteristic curves for the differential equation, the direct problem is generally ill posed.
The principal result about the dual problem is that, in any case (that is, regardless of the kind of boundary used), an elliptical differential problem with Dirichlet boundary conditions is obtained; it means considering a problem generally well posed.
To be more precise, if no cable is taken in account on membrane boundary, dual problem always returns an unique shape of membrane for each given tensions stress tensor (elliptical Dirichlet problem).
On the other hand the general dual problem (with cables) has a "no classical" formulation. In fact along the cable the unknown of the problem has contemporaneously to verify two conditions: one Dirichlet condition and other one (not standard) on the second derivatives of the membrane shape.
In the report a numerical method of resolution is presented. It consists on defining a "residual vector" that, once minimized, returns the nodal values of the membrane along the cables.

PLATÓN El patrimonio urbano como conservador de la memoria colectiva es el reflejo y referencia de la identidad de una sociedad, es un bien único e irremplazable cuyo mantenimiento depende de su reconocimiento por parte de esta sociedad. Muchos son los factores que configuran el patrimonio urbano y cualquier cambio en el espacio público puede producir lugares tanto de encuentro, como de paso o de abandono. La presente investigación muestra como la interactuación entre los diferentes agentes sociales, económicos, las administraciones públicas y las legislaciones que confluyen en los espacios más sensibles, como son los centros históricos protegidos, pueden provocar la formación de espacios frontera, micro-bordes, dentro de la ciudad consolidada. Durante el siglo XX se desarrollaron diversas teorías acerca de la conveniencia y las formas de intervenir en la ciudad, cada una con marcadas bases políticas y, fundamentalmente, económicas. Estas teorías, todas con el objetivo común de lograr ciudades de calidad, han dejado huella en la ciudad a través del planeamiento. En el presente estudio, centrado en la ciudad de Valencia, y en concreto en su Centro Histórico Protegido, Ciutat Vella, se han revisado la influencia y huellas de las distintas teorías urbanísticas surgidas en el último tercio del siglo XX; en su planeamiento y en cómo estas, junto a la legislación urbanística y patrimonial y los agentes sociales, han contribuido al cambio de la ciudad. Se parte de un modelo de ciudad tradicional compacta, formada por monumentos y viviendas colectivas que, teóricamente, favorecen la integración social. Una ciudad eficiente dotada de una buena urbanización, con unos servicios y una movilidad adaptados a las necesidades de desarrollo de su sociedad. Un ámbito de estudio con un importante legado histórico, una trama y un paisaje urbano heredados; son espacios que cuentan con las premisas legales de la conservación de su tejido urbano histórico y de los inmuebles con valores patrimoniales. La investigación ha permitido comprobar también, como al introducir cambios que provocan rotos en la trama o en la morfología urbana se puede generar el riego de hacer desaparecer esa ciudad heredada. La investigación ha analizado las intervenciones que la Administración ha llevado a cabo, durante la primera década del siglo XXI, en espacios de significado, importancia y reconocido valor patrimonial en la ciudad, con el objetivo de identificar los procesos y factores que pueden formalizar espacios frontera o bordes urbanos dentro de la ciudad consolidada. Teniendo en cuenta que cada barrio es diferente, tiene unas características físicas específicas, morfología, usos, actividades y espacios públicos propios, y que a estas singularidades se une la existencia de Bienes de Interés Cultural y de sus entornos de protección. Espacios singulares que actúan como focos estratégicos de gran atracción. El análisis se centra en cinco actuaciones urbanas promovidas por la Administración Local y que contaron, según marca la legislación, con la autorización y cautela patrimonial de la Administración Autonómica. El estudio se ha centrado en los siguientes espacios públicos del Centro Histórico Protegido: la Plaza de Décimo Junio Bruto, la Plaza del Patriarca, la Plaza del Pilar, la Plaza Redonda y la Plaza del Tossal. Los factores que pueden influir en la transformación de los espacios públicos dependen, entre otras cuestiones, de las oportunidades políticas y económicas, de la multifuncionalidad de cada espacio, de su adaptación a nuevos usos y de aspectos sociales relacionados con la calidad de vida de los habitantes. De ahí su variación y complejidad a la hora de elegir los elementos y aspectos que permitan el diagnóstico.
[CAT] RESUM DE LA TESI DOCTORAL Conéixer és Recordar. PLATÓ El patrimoni urbà com a conservador de la memòria col·lectiva és el reflex i referència de la identitat d'una societat, és un bé únic i irreemplaçable el manteniment del qual depén del seu reconeixement per part d'esta societat. Molts són els factors que configuren el patrimoni urbà i qualsevol canvi en l'espai públic pot produir llocs tant de trobada, com de pas o d'abandonament. La present investigació mostra com la interactuació entre els diferents agents socials, econòmics, les administracions públiques i les legislacions que confluïxen en els espais més sensibles, com són els centres històrics protegits, poden provocar la formació d'espais frontera, microbords, dins de la ciutat consolidada. Durant el segle XX es van desenvolupar diverses teories sobre la conveniència i les formes d'intervindre en la ciutat, cada una amb marcades bases polítiques i, fonamentalment, econòmiques. Aquestes teories, totes amb l'objectiu comú d'aconseguir ciutats de qualitat, han deixat empremta en la ciutat a través del planeament. En el present estudi, centrat en la ciutat de València, i en concret en el seu Centre Històric Protegit, Ciutat Vella, s'han revisat la influència i empremtes de les distintes teories urbanístiques sorgides en l'últim terç del segle XX; en el seu planejament i en com estes, junt amb la legislació urbanística i patrimonial i els agents socials, han contribuït al canvi de la ciutat. Es partix d'un model de ciutat tradicional compacta, formada per monuments i vivendes col·lectives que, teòricament, afavorixen la integració social. Una ciutat eficient dotada d'una bona urbanització, amb uns servicis i una mobilitat adaptats a les necessitats de desenvolupament de la seua societat. Un àmbit d'estudi amb un important llegat històric, una trama i un paisatge urbà heretats; són espais que compten amb les premisses legals de la conservació del seu teixit urbà històric i dels immobles amb valors patrimonials. La investigació ha permés comprovar també, com a l'introduir canvis que provoquen trencats en la trama o en la morfologia urbana es pot generar el risc de fer desaparéixer eixa ciutat heretada. La investigació ha analitzat les intervencions que l'Administració ha dut a terme, durant la primera dècada del segle XXI, en espais de significat, importància i reconegut valor patrimonial en la ciutat, amb l'objectiu d'identificar els processos i factors que poden formalitzar espais frontera o bords urbans dins de la ciutat consolidada. Tenint en compte que cada barri és diferent, té unes característiques físiques específiques, morfologia, usos, activitats i espais públics propis, i que a estes singularitats s'unix l'existència de Béns d'Interés Cultural i dels seus entorns de protecció. Espais singulars que actuen com a focus estratègics de gran atracció. L'anàlisi es centra en cinc actuacions urbanes promogudes per l'Administració Local i que van comptar, segons marca la legislació, amb l'autorització i cautela patrimonial de l'Administració Autonòmica. L'estudi s'ha centrat en els següents espais públics del Centre Històric Protegit: la Plaça de Décimo Junio Bruto, la Plaça del Patriarca, la Plaça del Pilar, la Plaça Redona i la Plaça del Tossal. Els factors que poden influir en la transformació dels espais públics depenen, entre altres qüestions, de les oportunitats polítiques i econòmiques, de la multifuncionalitat de cada espai, de la seua adaptació a nous usos i d'aspectes socials relacionats amb la qualitat de vida dels habitants. D'ací la seua variació i complexitat a l'hora de triar els elementsi aspectos que permetan el diagnòstic.

Cronje, Franci. "Border crossings : how students negotiate cultural borders during digital video production". Doctoral thesis, University of Cape Town, 2010. http://hdl.handle.net/11427/10299.
Texto completo da fonteThis thesis explores emerging patterns of communication in student video production and the extent to which such patterns signify cultural border crossings in a South African upper income group school context. The investigation was carried out with specific reference to the politics of difference, an educational philosophy defined by Henry Giroux (2006) as border pedagogy. Within the framework of multimodal pedagogy, four learners from diverse cultural backgrounds collaborated with one another in a timeframe of three days to create digital video productions using guidelines provided by the researcher. The production unit was observed in order to answer questions around the utilisation of video production in the classroom, as well as how learners interact and negotiate cultural issues while producing video. The data was analysed with a custom-made multimodal toolkit as proposed by Baldry and Thibault (2006). By employing Kress and Van Leeuwen's four strata of Discourse, Design, Production and Distribution various types of data illuminated themes around social memory, race, the influence of class difference, and gender representation. Assessment techniques in terms of the multimodal theories of Kress and Van Leeuwen (2001) also enabled the researcher to look at the way in which meaning is made "in any and every sign, at every level, and in any mode" (Kress & Van Leeuwen, 2001: 4). The classroom intervention was designed to encourage adolescents as "unique hybrids" (Bhabha 1994) to cross borders of cultural identity, hypothesising that difference might emerge more clearly in the negotiation and video production process, than what might crystallise in analyzing the final video production. Metaphorical border crossing in a cultural and racial sense might become more apparent in production than final product. The negotiation of Border Difference took preference over the ultimate erosion of these borders.

Texto completo da fonteLos logros alcanzados son:
· Análisis comparativo de dos tipos de cámara para la adquisición de imagen digital en color: videocámara de arquitectura 3CCD y cámara fotográfica con sensor CMOS multicapa. Caracterización del funcionamiento de la cámara con fines colorimétricos. Medida de la calidad a partir de la sensibilidad espectral y ruido producido en la imagen.
· Evaluación de la capacidad de la cámara para medir pequeñas diferencias de color entre pares de muestras. Comparación de la respuesta de la cámara con un instrumento de referencia de elevada precisión. Elaboración de tests de muestras que permitan realizar esta evaluación, afinando en la presentación de pequeñas diferencias de color, explorando la respuesta de la cámara en regiones del espacio de color que puedan implicar dificultad, o que presenten interés por su repercusión industrial, etc. Se ha usado la métrica CIELAB y CIEDE 2000, recomendadas por la CIE.
· Diseño de un método para el realce de la imagen en color inspirado en los modelos computacionales de la visión humana. Realce de los contornos de una imagen en color considerando las condiciones de observación y las características del dispositivo (monitor) que se utiliza para presentar la imagen. Combinación del operador de realce de derivada segunda con el suavizado mediante funciones gaussianas y todo ello, a su vez, con el espacio S-CIELAB, definido para medir distancias de color entre imágenes tal y como son percibidas en unas condiciones de observación determinadas. Análisis de las limitaciones del método que den lugar a efectos no deseados, desviaciones de color, presencia de ruido, etc. Estudio de variantes y aproximaciones del método que puedan presentar ventajas por implicar algún tipo de simplificación en su aplicación o por rebajar los requerimientos de cómputo.
· Desarrollo de aplicaciones de visión artificial para la ejecución de tareas que habitualmente son exclusivas de técnicos y especialistas con visión entrenada en diversos campos: Inspección de la uniformidad del color en muestras textiles, análisis de imágenes estándar para la graduación de las complicaciones producidas por el uso lentes de contacto y análisis de imágenes del fondo de ojo para la ayuda al diagnóstico precoz y seguimiento del glaucoma. Obtención de resultados experimentales, análisis y extracción de conclusiones.
Esta tesis contribuye a aumentar las capacidades potenciales de los sistemas de visión artificial para ser utilizados en aplicaciones que requieren una evaluación e interpretación de la información de color en imágenes digitales. Estas aplicaciones tradicionalmente se llevan a cabo mediante la visión humana entrenada de técnicos o especialistas y pueden mejorar notablemente si se incrementa en ellas la objetividad y la automatización.
This doctoral dissertation addresses a range of practically motivated research objectives related to the acquisition, measurement, representation and processing of colour information contained in digital images. The characterization of imaging devices (cameras) has allowed the author to determine their best working conditions for colorimetric applications. New tools of image analysis have been developed to automatically or partly automatically measure small colour differences, sharpen images and segment objects. All these operations have been related to similar operations of the human vision performance.
The work includes both experimental and numerical elements in a variety of applications: industrial inspection (colour uniformity assessment of textile dyeing), colour image sharpening, and analysis of ophthalmic images (feature extraction in reference images of complications related to wearing contact lenses and characterization of retina fundus images for glaucoma diagnosis and monitoring).
The specific achievements are:
· Comparative analysis of two types of digital cameras: 3CCD camera and multilayer silicon sensor camera. Characterization of camera performance for colorimetric purposes. Calculation of measure of goodness that involve both the spectral sensitivities and imaging noise of the camera.
· Evaluation of the capabilities of digital cameras to measure small colour differences between sample pairs by comparing the camera performance with a reference instrument. Design of specific tests of colour samples. Particular attention is paid to the nearly neutral region of the colour space (very pale and the dark greyish colours) that entails certain degree of difficulty. It has been used metric CIELAB and CIEDE 2000, recommended by the CIE.
· Design of a method for image sharpening based on human colour vision models. The method combines second derivative operators with the spatial-CIELAB space defined to measure colour distances between images. A colour image is sharpened taking into account the viewing condition of the observer and the characteristics of the monitor used to display. The method has been demonstrated to yield better results than conventional methods. Possible artifacts are explored and evaluated.
· Several applications in different fields have been developed: Application to colour matching assessment by machine vision in textile industry; application to the analysis of standard images to grade the complications produced by contact lens wear in optometry, and application to the analysis of ophthalmic images related to glaucoma.
Numerical and experimental results are obtained and discussed.
This doctoral dissertation contributes to increase the potential capabilities of artificial vision systems based on digital images in colour to be used in applications involving analysis of colour images which traditionally require the involvement of human specialists or technicians and that still remain far from objectiveness and automation.

Texto completo da fonteThis study considers how Serbian border security sector reform illuminates questions of force and statecraft in a southern European nation. In 2006, Serbia became a member of the Partnership for Peace (PfP), a step toward a North Atlantic Treaty Organization (NATO) membership; however, Serbia has indicated no intention to become a full NATO member. Also in 2006, Serbia entered into a Stabilization and Association Agreement (SAA) with the European Union (EU) as part of the process of accession to EU membership; however, Serbia must meet EU conditions regarding border security reform and must continue to cooperate with the International Criminal Tribunal for Yugoslavia (ICTY) for full membership to be realized. This thesis evaluates Serbia's continued efforts to integrate into the EU structures. It begins with a historical overview of the leadership, politics and reform of the Serbian security sector before the 21st century. It then explores the role of the international community, including Russia, in providing assistance to Serbia during the past decade. The thesis then focuses on Serbia's progress in border security development, Integrated Border Management (IBM), border guard reform and customs administration reform. This thesis argues that, despite the on-going efforts of the international community to integrate Serbia into the EU community, due to the unique political and social circumstances specific to Serbia regarding comprehensive reform of ethics and power, the continuing border security reform efforts in Serbia-and hence, EU membership-will most likely remain another decade in the future.

Texto completo da fonteWith a surface area of 4,400 km2 and a 13-million population, the Greater Buenos Aires urban agglomeration is one of the main urbanized areas of Latin America. In addition, the space over which the city exerts its regional influence – the Metropolitan Region – covers about 15,000 km2. In the production belt located in its fringe, about 1,500 horticultural production units occupy 16,000 hectares, supplying roughly 30% of the urban fresh food demand. Out of this surface area, 3,000 pertain to surface area occupied with greenhouses, which in turn represents 40% of the national surface area of crops under roof. Over the last decades, economic agents of Bolivian origin have come to play a central role in the production and marketing of such products. As a result of the context emerging from the national economy crisis of year 2001, in which food supply into the cities became relevant and the State abandoned the “New Public Management” paradigm of the 1990s to center on interventions much more focused on the social aspects, over the last ten years, agriculture in the rural-urban fringe has increasingly gained space in the public agenda. Between years 2000 and 2008, different municipalities of the periphery of the Buenos Aires Metropolitan Region have wrought policies to manage their urban-rural interfaces (case studies: Moreno, Florencio Varela and Pilar), and within the Province of Buenos Aires, a Provincial Office of Periurban Agriculture acquired institutional rank. The creation by the National Institute of Agricultural Technology of a metropolitan agency specialized in urban and periurban agriculture, and the introduction by the National Ministry of Agriculture of a National Program of Periurban Agriculture during 2009 and 2010 took things to a whole new level. Technical experts of municipal rank played a key role in the above processes, as they went above the State’s upper structures. However, the generation of new initiatives to manage territories as complex as the urban-rural fringe – when attempting to influence its planning in a coordinated manner – has run into the traditional fragmentation of the State system. The initiatives have also come across a poor definition of specific territorial agendas or a dilution thereof in the face of the preponderance of sectoral agenda. In a few words, this dissertation seeks to present a relation on the different municipal, provincial and national policies proposing to intervene in the productive environs of Buenos Aires, inquiring on the need to build a new metropolitan institutional framework and to apply specific instruments of intervention, presently available or to be created in the future, intended to watch over periurban agriculture. Likewise, quality control and phytosanitary inspectorate are treated as main issues in horticultural public management. The research has a qualitative approach. Field trips interviews and observations, focusing on gathering public agents', marketers' and horticultural producers' experiences, were used as methods for collecting the data. As well, it is based on scientific specialized literature and technicals documents on periurban agriculture. Furthermore, the methodology that allows to study the situation of government and state institutions is linked with a descriptive model for public policy analysis.

Texto completo da fonteThe objective of this thesis is to explore the mortality trends in the United States’ border regions. Using the Center of Disease Control and Prevention’s WONDER database, we examine overall mortality from 1999-2019 through the calculation of standardized mortality ratios for the border region versus the non-border areas. We analyse sub-populations of the border by state, ethnicity, and cause of death, and we use varying combinations of confounders in our standardization including age, gender, and cause of death. The findings confirm significant differences between the border and non-border regions, with opposite results at each border. When accounting for all confounders, the border region at the Mexican border (SMR = 0.958) has lower mortality than the non- border region (SMR = 1.011), and at the Canada border, the border region (SMR = 1.033) has higher mortality than the non-border region (SMR = 0.985). In this manner, the county of residence and proximity to the border could be a useful contributor to mortality estimations.

Texto completo da fonteThis work aims to name and define theatricals overflows present on the contemporary stage. It aims to reveal their meaning with regard to theatrical practice, but also to our society. Whether they are within the creation itself or whether they concern the spectators, the spatio-temporal, dramaturgical, idological, interpretative, spatial, performative of emotional overflows raise the question of the meeting of the living with the fixity of theatricals borders, and in particular the edge of the stage. It is a question of thinking about the way in which directors such as Vincent Macaigne, Thomas Ostermeier or Rodrigo García attempt or succeed in practising off-stage staging in an agreed architectural space that is the Theater. The increasing crossing of the theater stage by, among other things, bodies, materials, cultures or disciplines, reexamines the definitions and functions of theater as well as the place, the function and the role of the spectator, but also changes the work of the director, the playwright, the comedian and the stage manager. Multidisciplinarity and interdisciplinarity force the theatre-medium to adapt and to invest new creative spaces such as the in-between space to the point of disrupting spectator reception. We study the mechanisms that allow us to "get out of", whether it be in this desire to disturb or to sublimate through the practice of the performance art in particular. So, we can wonder us what it is to "having one's place in front of or within a performance" ? And how does the aesthetics of theatrical overflow immerse the spectators in an emancipatory experience ?

Texto completo da fonteBeing non-invasive and having low cost, the echocardiography has been largely applied as diagnostic technique for left ventricle systolic and diastolic volumes determination that indirectly are used to calculate the left ventricle ejection volume, the cardiac cavities muscular contraction, the regional and global ejection fraction, the myocardial thickness, the ventricular mass, etc. For this reason, the detection of the left ventricle endocardial borders become necessary, but hampered by the noise that impairs the echocardiography images definition. In spite of having many image segmentation techniques, this work intend to detect the borders of left ventricle on echocardiography images by using a artificial neural network to recognize border patterns. To accelerate the process and facilitate the procedure, the operator uses the mouse to define a rectangular region inside the acoustic window of the pacient where all analyses and border recognitions will be accomplished. After labeling the recognized points as \'border\', gradient techniques and mobile boundary are used to connect the points of greater probability and delineate the left ventricle border. This technique has proved to be efficient when compared to the borders traced by the specialist. The ability of the operator is important in choosing of the region to be analyzed. After training with 50 samples of \"border\" pattern and 10 samples of \"no-border\" pattern, this technique was tested on 108 images, achieving good results on precision and velocitiy when we compared the calculated left ventricle area with the results of other techniques published on national and international literature.

Texto completo da fonteThe thesis analyses EU’s evermore complex borders and border management in a time where migration and borders have become an increasingly important subject in politics and with EU´s citizens. The purpose of the thesis is to get a deeper understanding of the modern border and border-practises beyond the classic view of territoriality within international relations. The study is a discourse analysis of the European border and cost guard agency Frontex yearly risk analysis published between 2014- 2018. A post-structuralistic analysis inspired by ”Critical Border Studies” where Michel Foucaults understanding of power and productive power is used. The thesis focus is on exposing Frontex discursive power and power-practises related to EU’s southern outer border with the application of Foucaults concept of productive power on Frontex discursive representation of EU’s southern outer border. The study shows how Frontex actions, ways to analys and view the boarder, and there on operation clearly focuses on the productive power to change behaviour, outlook and the possibility to act.

Texto completo da fonteThe image sensor, nowadays, is rolling the smartphone industry. While some phone brands explore equipping more image sensors, others, like Google, maintain their smartphones with just one sensor; but this sensor is equipped with Deep Learning to enhance the image quality. However, what all brands agree on is the need to research new image sensors; for instance, in 2015 Omnivision and PixelTeq (sensor manufacturers) presented new CMOS based image sensors, which are capable of capturing multispectral bands, these sensors are defined as multispectral Single Sensor Camera (SSC). This dissertation presents the benefits of using a multispectral SSCs that, as aforementioned, simultaneously acquires images in the visible and near-infrared (NIR) bands. The principal benefits while addressing problems related to image bands in the spectral range of 400 to 1100 nanometers, there are cost reductions in the hardware setup because only one SSC is needed instead of two; moreover, the cameras’ calibration and images alignment are not required any more. Concerning to the NIR spectrum, even though this band is close to the visible band and shares many properties, the sensor sensitivity is material dependent due to different behavior of absorption/reflectance capturing a given scene compared to visible channels. Many works in literature have proven the benefits of working with NIR to enhance RGB images (e.g., image enhancement, remove shadows in the RGB images, dehazing, etc.). In spite of the advantage of using SSC (e.g., low latency), there are some drawback to be solved. One of this drawback corresponds to the nature of the silicon-based sensor, which in addition to capture the RGB image, when the infrared cut off filter is not installed it also acquires NIR information into the visible image. This phenomenon is called RGB and NIR crosstalking. This thesis firstly faces this problem in challenging images and then it shows the benefit of using multispectral images in the edge detection task. The RGB color restoration from RGBN image is the topic tackled in RGB and NIR crosstalking. Even though in the literature a set of processes have been proposed to face this issue, in this thesis novel approaches, based on DL, are proposed to subtract the additional NIR included in the RGB channel. More precisely, an Artificial Neural Network (NN) and two Convolutional Neural Network (CNN) models are proposed; as the DL based models need a dataset with a large collection of image pairs (RGB infected by NIR and target RGB image), a large dataset is collected to address the color restoration. The collected images are from challenging scenes where the sunlight radiation is sufficient to give absorption/reflectance properties to the considered scenes. An extensive evaluation has been conducted on the CNN models, differences from most of the restored images are almost imperceptible to the human eye. The next proposal of the thesis is the validation of the usage of SSC images in the edge detection task. Three methods based on CNN have been proposed. While the first one is based on the most used model, holistically-nested edge detection (HED) termed as multispectral HED (MS-HED), the other two have been proposed observing the drawbacks of MS-HED. These two novel architectures have been designed from scratch (training from scratch); after the first architecture is validated in the visible domain a slight redesign is proposed to tackle the multispectral domain. Again, another dataset is collected to face this problem with SSCs. Even though edge detection is confronted in the multispectral domain, its qualitative and quantitative evaluation demonstrates the generalization in other datasets used for edge detection, improving state-of-the-art results.

A feature of many conflicts is the presence of a border that separates an area of on-going military operations from an area that the enemy can use permissively. This thesis considers analytic techniques for planning military operations designed to interdict enemy forces crossing the border. Specifically, this thesis presents optimization-based methods for scheduling patrolling units and for positioning ground sensors in support of those patrolling units. These methods could serve as the framework for a tactical-level decision support tool designed to assist military planners assigned to border regions with resource allocation recommendations and trade-off comparisons. We propose tractable mixed integer optimization formulations for these solutions based on a network model of the routes in the region, operational constraints on the abilities of the patrolling units, and estimates of enemy force movements. Additionally, we develop robust extensions to these formulations that allow the model to account for a degree of enemy intelligence by incorporating the uncertain nature of the enemy movement estimates into the formulation. We evaluate the solutions to these formulations using simulations that account for different realizations of the uncertain enemy movement. This includes cases where the realized enemy movement closely matches the estimates made in the model and cases where the realizations are very different from the model. Additionally, we provide a modified greedy heuristic to the scheduling formulation that can serve as a tool for dynamically retasking a patrol to interdict enemy forces in real-time after a sensor detects enemy movement. Current planning for these operations are conducted by a staff with no decision making analytic tools. We approximate a version of this current planning method with an algorithm and show that our method outperforms it with both the deterministic and robust formulations. We compare the deterministic and robust formulations and demonstrate a process for choosing between the formulations, along with an explanation of the utility of the robust formulation.
