Implementation of intelligent data acquisition system for ITER fast controllers using RIO devices.

A basic requirement of the data acquisition systems used in long pulse fusion experiments is the real time physical events detection in signals. Developing such applications is usually a complex task, so it is necessary to develop a set of hardware and software tools that simplify their implementation. This type of applications can be implemented in ITER using fast controllers. ITER is standardizing the architectures to be used for fast controller implementation. Until now the standards chosen are PXIe architectures (based on PCIe) for the hardware and EPICS middleware for the software. This work presents the methodology for implementing data acquisition and pre-processing using FPGA-based DAQ cards and how to integrate these in fast controllers using EPICS.

Node sampling using random centrifugal walks

Sampling a network with a given probability distribution has been identified as a useful operation. In this paper we propose distributed algorithms for sampling networks, so that nodes are selected by a special node, called the source, with a given probability distribution. All these algorithms are based on a new class of random walks, that we call Random Centrifugal Walks (RCW). A RCW is a random walk that starts at the source and always moves away from it. Firstly, an algorithm to sample any connected network using RCW is proposed. The algorithm assumes that each node has a weight, so that the sampling process must select a node with a probability proportional to its weight. This algorithm requires a preprocessing phase before the sampling of nodes. In particular, a minimum diameter spanning tree (MDST) is created in the network, and then nodes weights are efficiently aggregated using the tree. The good news are that the preprocessing is done only once, regardless of the number of sources and the number of samples taken from the network. After that, every sample is done with a RCW whose length is bounded by the network diameter. Secondly, RCW algorithms that do not require preprocessing are proposed for grids and networks with regular concentric connectivity, for the case when the probability of selecting a node is a function of its distance to the source. The key features of the RCW algorithms (unlike previous Markovian approaches) are that (1) they do not need to warm-up (stabilize), (2) the sampling always finishes in a number of hops bounded by the network diameter, and (3) it selects a node with the exact probability distribution.

Teaching based on the case method of building collective protection

One of the fundamental aspects in the adaptation of the teaching to the European higher education is changing based models of teacher education to models based on student learning. In this work we present an educational experience developed with the teaching method based on the case method, with a clearly multidisciplinary. The experience has been developed in the teaching of analysis and verification of safety rails. This is a multidisciplinary field that presents great difficulties during their teaching. The use of the case method has given good results in the competences achieved by students

Analysis of teaching experience based on teaching by the case method. Application to reinforcing wooden floors

The technique of reinforcement of wooden floors is a matter clearly multidisciplinary. The teaching of the subject using the "traditional" method, explaining the theory first and then proposing and solving problems has not been successful. This paper discusses the results of a teaching experiencie. It has been the teaching of the subject by the case method. The results are clearly superior to those obtained with the traditional methodology.

Supporting pruning in tabled LP

This paper analyzes issues which appear when supporting pruning operators in tabled LP. A version of the once/1 control predicate tailored for tabled predicates is presented, and an implementation analyzed and evaluated. Using once/1 with answer-on-demand strategies makes it possible to avoid computing unneeded solutions for problems which can benefit from tabled LP but in which only a single solution is needed, such as model checking and planning. The proposed version of once/1 is also directly applicable to the efficient implementation of other optimizations, such as early completion, cut-fail loops (to, e.g., prune at the top level), if-then-else, and constraint-based branch-and-bound optimization. Although once/1 still presents open issues such as dependencies of tabled solutions on program history, our experimental evaluation confirms that it provides an arbitrarily large efficiency improvement in several application areas.

A syntactic and functional correspondence between reduction semantics and reduction-free full normalisers

Olivier Danvy and others have shown the syntactic correspondence between reduction semantics (a small-step semantics) and abstract machines, as well as the functional correspondence between reduction-free normalisers (a big-step semantics) and abstract machines. The correspondences are established by program transformation (so-called interderivation) techniques. A reduction semantics and a reduction-free normaliser are interderivable when the abstract machine obtained from them is the same. However, the correspondences fail when the underlying reduction strategy is hybrid, i.e., relies on another sub-strategy. Hybridisation is an essential structural property of full-reducing and complete strategies. Hybridisation is unproblematic in the functional correspondence. But in the syntactic correspondence the refocusing and inlining-of-iterate-function steps become context sensitive, preventing the refunctionalisation of the abstract machine. We show how to solve the problem and showcase the interderivation of normalisers for normal order, the standard, full-reducing and complete strategy of the pure lambda calculus. Our solution makes it possible to interderive, rather than contrive, full-reducing abstract machines. As expected, the machine we obtain is a variant of Pierre Crégut s full Krivine machine KN.

Novel techniques for automorphism group computation

Graph automorphism (GA) is a classical problem, in which the objective is to compute the automorphism group of an input graph. In this work we propose four novel techniques to speed up algorithms that solve the GA problem by exploring a search tree. They increase the performance of the algorithm by allowing to reduce the depth of the search tree, and by effectively pruning it. We formally prove that a GA algorithm that uses these techniques correctly computes the automorphism group of the input graph. We also describe how the techniques have been incorporated into the GA algorithm conauto, as conauto-2.03, with at most an additive polynomial increase in its asymptotic time complexity. We have experimentally evaluated the impact of each of the above techniques with several graph families. We have observed that each of the techniques by itself significantly reduces the number of processed nodes of the search tree in some subset of graphs, which justifies the use of each of them. Then, when they are applied together, their effect is combined, leading to reductions in the number of processed nodes in most graphs. This is also reflected in a reduction of the running time, which is substantial in some graph families.

La iglesia de Santiago de los españoles en Roma y su entorno entre los siglos XV y XIX. Una historia a través del dibujo

Plaza Navona representa una de las visitas obligadas de Roma, pero solo algunos advertirán en ella la presencia española en la sala de exposiciones del Instituto Cervantes o en la inmediata Libreria Española. Todavía serán menos los que se percatarán de la huella española dejada en aquella iglesia de fachada anónima situada, en el extremo sur de la plaza: la antigua iglesia de Santiago de los Españoles. La presente tesis pretende, utilizando el dibujo como guía, herramienta y fin del proceso de análisis y estudio, reconstruir el proceso de conformación y construcción de la que fue iglesia española principal, cuya fundación hace patente el destacado papel jugado por la “nación” castellana en Roma durante la Edad Media; y en torno a la que se aglutinaron las actividades religiosas, diplomáticas y financieras de los castellanos que vivieron en la actual capital italiana. Se intentará recrear en el tiempo la que es hoy la iglesia de Nuestra Señora del Sagrado Corazón, sometiéndola a una restitución gráfica disciplinada, homogénea y objetiva en la medida de lo posible de las varias etapas que la han caracterizadas, desde su fundación hasta cuando en 1878 España se deshizo de ella, ya en ruina, vendiéndola. Como nos comenta Gaetano Moroni, de todas las comunidades nacionales que se encontraban en Roma la española parece ser efectivamente una de las más rica y prestigiosa. Aunque lo que no cuenta Moroni no haya sido todavía demostrado, dicho enunciado resulta de todas formas interesante puesto que pone el acento sobre el hecho de que ya desde el siglo X parece ser habitual de ocupar y reutilizar antiguas ruinas, usándolas como base para la construcción de hospitales para los peregrinos. Esta operación se hizo particularmente frecuente sobre todo antes del Gran Jubileo de 1450: de hecho desde la primera mitad del Quattrocento se fundan distintas iglesias y hospitales nacionales para acoger y prestar una adecuada asistencia y socorro a los innumerables peregrinos que llegaban a la ciudad, edificios que se van construyendo sobre los restos de antiguos edificios de época romana. Prueba de ello es en efecto la fundación originaria de la iglesia y hospital de los Españoles que, parte del conjunto de edificios que compone la Plaza Navona, situada en el corazón de Campo Marzio y cuya posición y forma corresponden a la del antiguo Estadio de Domiciano, y que ahora es en sus dimensiones, en su imagen arquitectónica y en su consistencia material, el resultado de la definición proyectual y de las transformaciones que se llevaron a cabo sobre lo que quedaba del antiguo templo español del siglo XV, entre finales del ‘800 y los años 30 del siglo XX . Transformaciones devastadoras, huellas grabadas o canceladas que encuentran una justificación en los acontecimientos históricos reflejados en el patrimonio urbano. El análisis de todas las fuentes permite trazar, si no la totalidad, buena parte de las modificaciones que la antigua iglesia de Santiago ha sufrido. La construcción del templo se puede dividir en tres momentos decisivos: una primera etapa de fundación en 1450-1478 en la que la iglesia tenía fachada y entrada en via de la Sapienza, hoy Corso Rinascimento; una segunda de significativa ampliación hacia Plaza Navona con una nueva fachada monumental hacia ese espacio público en 1496-1500; y una última importante ampliación entre 1525-1526, llevada a cabo por el arquitecto Antonio da Sangallo el Joven. Tras la intensa vida del templo, en el siglo XVIII, éste cae en ruina y finalmente es vendido en 1878 a la orden de los misioneros franceses de Nuestra Señora del Sagrado Corazón que la reconvierten en iglesia reformando totalmente el conjunto en 1881, según proyecto de Luca Carimini. En 1936, en plena fase de rectificación de trazados urbanos por obra del régimen fascista, según proyecto de Arnaldo Foschini, se mutila su extremidad hacia vía de la Sapienza dejando su estado tal y como se contempla en la actualidad. ABSTRACT The objective of this thesis is the reconstruction of the design and edification process -using drawings and sketches as a guide, tool and the end of the analytical process- of a church which was once the preeminent Spanish church in medieval Rome, known today as Nostra Signora del Sacro Cuore (Our Lady of the Sacred Heart). The founding of this church illustrates the important role held by the Castillian “nation” in Rome during the Middle Ages. It was the focal point of all the religious, diplomatic and economic activities of the Castillian community residing in today’s Italian capital. The aim of this proyect is a recreation the church in time by submitting it to a disciplined, homogenous and objective graphic restitution of the various stages most characteristic the temple, starting from its foundation until 1878 when, in a state of ruins, the church was finally sold off by Spain. Gaetano Moroni once commented that of all the international communities found in Rome, the Spanish community seemed to be one of the wealthiest and most prestigious. Such a statement proves interesting as it emphasizes that starting in the 10th century we see there was a widespread custom of occupying and reusing old ruins for use as the bases of new constructions of hospitals for pilgrims. This custom became especially frequent just before the Jubilee Year of 1450: in fact, in the first half of the Quattrocento we see the founding of many different national churches and hospitals which provided shelter and care to the countless pilgrims arriving in the city, buildings which were constructed on top of the ruins of ancient buildings left over from Roman times. Proof of this is the original foundation of the Spanish church and hospital forming part of the Piazza Navona, built upon and following the outline of the Stadium of Domitian, in the heart of Campo Marzio. Now, in its dimensions, its architectural image and its material substance, it represents the predominant result of the planning definitions and the transformations which affected the old 15th-century Spanish temple. Ocurring between the end of the 19th century and the 1930s, the transformations were devastating, erasing original peculiarities and engraving new ones, transformations made justifiable by the historical events reflected in its urban environs. Analyzing all sources allows us to trace, even if not in entirety, still a sizeable portion of the modifications undergone by the old Church of Saint James. The construction of the temple can be divided into three decisive moments: its foundation, from 1450 to 1478, when the church’s façade and main door looked out on to the Via della Sapienza, today’s central avenue of Corso del Rinascimento; the second stage being a major expansion towards the Piazza Navona (1496-1500) with a new, monumental façade facing the public space; and the third was the last significant expansion, carried out from 1525 to 1526 by the architect Antonio da Sangallo the Younger. Despite an intense and bustling life during the Modern Age, in the 18th century the church began to fall into ruin and was finally sold in 1878 to the order of French missionaries of Our Lady of the Sacred Heart, who reconverted it into a church and completely renovated the structure in 1881 in a project supervised by Luca Carimini. In 1936, the corrective urban redesign of Rome carried out by the fascist regime and implemented by Arnaldo Foschini mutilated the part bordering Via della Sapienza, leaving it as we see it today.

Criterios de restauración, intervención y revitalización del patrimonio industrial : la fábrica de gas de San Paolo en Roma

La tesis está centrada en el patrimonio industrial, y trata de ahondar en los temas enunciados en el título, Criterios de restauración, intervención y revitalización del patrimonio industrial (capítulo 1). La fábrica de gas de San Paolo en Roma (capítulo 2): En el primer capítulo, se profundiza en los criterios institucionalizados de actuación en el patrimonio, pero también se habla sobre la singularidad, los valores originales, estratificados en cada construcción y su contexto. Ello resume la intención de la doctoranda al entender la necesidad del análisis de cada obra en modo profundo, concreto y abierto a novedosos acercamientos, antes de su transformación. Al hablar de intervención frente a restauración, se aborda la conocida polémica que plantea el modo de acercarse al legado histórico. Parece necesario enunciar cómo se consideran en el trabajo estos términos. Mientras la restauración (como diría Cesare Brandi, constituye el momento metodológico del reconocimiento de la obra de arte en su consistencia física y en su doble polaridad estética e histórica, en orden a su transmisión al futuro) es una acción más restrictiva, que implica atención suma a la recuperación y conservación de los valores significativos y únicos del bien, en comunicación con un (posible) equipo interdisciplinar; por intervención se entiende aquí un desarrollo más personal y libre por parte del proyectista, en el que se produce un proceso dialéctico entre la preexistencia y el posicionamiento crítico adoptado a la hora de dar un obligado nuevo uso a ese bien. Es decir, el contraste está en el diferente reconocimiento de la materialidad física y sus significados. En torno a la restauración/intervención, se analizan las perspectivas de actuación en España e Italia, contrastando factores como la formación del arquitecto o el entorno laboral-cultural, y utilizando el método analítico comparativo de casos. Habría un tercer concepto: el de revitalización del patrimonio industrial, Éste hace referencia a su transformación, a sus usos más comunes y compatibles, a la redimensión artística que ha experimentado la arquitectura industrial gracias al arte contemporáneo y a su relación con la Modernidad. Por último, se enuncia en el título el caso de estudio, la Fábrica, que ocupa el segundo capítulo. Se trata de un enorme conjunto industrial singular semi abandonado en el confín del centro histórico, cuyo protagonista es un gran gasómetro, que la autora ha tenido la oportunidad de descubrir en su estancia en la Ciudad Eterna. Este barrio constituyó el primer y único sector industrial de la Roma moderna a inicios del siglo XX. Por varias causas históricas y voluntad política, la ciudad prácticamente no tuvo más desarrollo industrial que el área mencionada, donde se implantaron servicios y actividades de gran transformación (Matadero, Mercados Generales, Almacenes Fluviales, Central Montemartini o esta fábrica). A partir de 1920, se empezó a construir un tejido productivo que la llevó de la situación de posguerra al milagro económico. Frente al mito de la Roma monumental o de la Roma cotidiana, aparece el aspecto industrial como mito de la contemporaneidad. Sin embargo, esta ciudad es demasiado antigua como para convertirse en moderna, y su proceso industrial en contraste con su larga historia resulta breve. La inmediata relación de la fase industrial romana con el resultado de este desarrollo viene identificada con las instalaciones señaladas, más significativas por su excepcionalidad que por la duración del momento irrepetible que representan. Su presencia física perdura a pesar de su abandono, aisladas tras su muro perimetral y casi desconocidas. Esto las hace apetecibles para la especulación inmobiliaria y resultan un caso de estudio ideal para realizar un Plan de Intervención Global, en el que determinar una serie de intervenciones necesarias, usos compatibles y directrices para la ordenación del conjunto, coherentes con los conceptos manejados en el primer capítulo. ABSTRACT The thesis focuses on industrial heritage, delving into the topics listed in its title, Criteria for the restoration, intervention and revitalisation of industrial heritage (chapter 1). The San Paolo gas factory in Rome (chapter 2): Chapter one elaborates on the official criteria to take action on heritage, but also deals with the singularity and original values unique to each construction and its context. This underlines the PhD candidate’s intentions by understanding the need for an in-depth and specific analysis, open to novel approaches to each site before its transformation. When speaking of intervention, as opposed to restoration, we address the well-known controversy that stems from the different ways of approaching historical heritage. It seems necessary to explain how these terms are interpreted in this piece of work. Whereas restoration (as Cesare Brandi would say, constitutes the methodological moment in which the work of art is appreciated in its material form and in its historical and aesthetic duality, with a view to transmitting it to the future) is a more restrictive action, demanding the utmost attention to the recovery and preservation of the piece of heritage’s defining and exceptional values, (ideally) in communication with a interdisciplinary team. By intervention, we hereby understand a more personal and free procedure carried out by the designer in which a dialectical process takes place between preexistence and the critical stance taken in order to give that good a much needed new use. That is, contrast lies in the different recognition of physical materiality and its meanings. As for the restoration/intervention dilemma, the different courses of action followed in Spain and Italy will be analysed, contrasting the architects’ training, the labourcultural environment and taking an analytical comparative case study method. There is a third concept: the revitalisation of industrial heritage, which refers to its transformation, its most common and compatible uses, the artistic redimensioning that industrial architecture has experienced thanks to contemporary art, and its relationship with Modernity. Lastly, the title refers to the case study, i.e., the analysis of the Factory, which makes up chapter 2. It is an enormous and semiabandoned peerless industrial complex on the edge of the historical city centre whose main landmark is a huge gasometer, which the author had the chance to discover during her stay in the Eternal City. This district made up the first and only industrial sector in the modern Rome of the early 20th century. Due to a number of reasons, both historical and political, barely no further industrial development took place in the city beyond the mentioned area, where processing services and activities were set up (Slaughterhouse, General Markets, Riverside Warehouses, Montemartini Power Plant or the said factory). In the 1920s began the construction of the productive fabric that raised the city from its postwar plight to the economic miracle. As opposed to the myth of monumental Rome and daily-life Rome, this industrial Rome rose as contemporaneity’s myth. However, this city is too ancient to become modern, and its industrial process strikes us as brief when confronted with its long history. The close relationship between Rome’s industrial stage and the consequences of this development is best represented by the aforementioned facilities, more relevant due to their uniqueness than the length of the once-in-a-lifetime moment they represent. Their physical presence lives on despite abandonment and isolation, as they stand vastly unknown behind their perimeter walls. This renders them appealing to property speculators, becoming an ideal case study for the creation of a Global Intervention Plan in which to determine a series of necessary actions, compatible uses and directives, all of them consistent with the concepts dealt with in chapter 1. RIASSUNTO La tesi è focalizzata sul patrimonio industriale e cerca di approfondire le tematiche contenute nel titolo, Criteri di restauro, intervento e rivitalizzazione del patrimonio industriale (capitolo 1). La Fabbrica del gas di San Paolo a Roma (capitolo 2): Nel primo capitolo vengono presi in esame i criteri istituzionalizzati di attuazione nel patrimonio, ma si parla anche della unicità, i valori originali, stratificati in ogni costruzione ed il suo contesto. Questo riassume l’intenzione della dottoranda di capire la necessità dell’analisi di ogni opera in modo profondo, concreto e aperto a nuovi approcci, prima della sua trasformazione. Nel parlare di intervento versus restauro, si affronta la famosa polemica che considera il modo di avicinarsi all’eredità storica. Appare necessario precisare come questi termini sono considerati in questo lavoro. Mentre il restauro (come direbbe Cesare Brandi, costituisce il momento metodologico del riconoscimento dell’opera d’arte nella sua consistenza fisica e nella duplice polarità estetica e storica, in vista della sua trasmissione nel futuro) è un’azione più restrittiva, e quindi implica massima attenzione al recupero e conservazione dei valori significativi ed unici del bene, in comunicazione con una (eventuale) squadra interdisciplinare; per intervento si intende qui un processo più personale e libero del progettista, nel quale si produce uno sviluppo dialettico tra la preesistenza e la posizione critica adottata quando si deve dare un nuovo uso di quel bene. Vale a dire che il contrasto risiede nel diverso riconoscimento della materialità fisica e i loro significati. Intorno al restauro / intervento, si analizzano le prospettive di attuazione in Spagna e Italia, contrastando diversi fattori come la formazione dell’architetto o l’ambiente lavorativo-culturale, ed impiegando il metodo analitico comparativo dei casi. Ci sarebbe un terzo concetto: quello della rivitalizzazione del patrimonio industriale. Questo fa riferimento alla sua trasformazione, ai suoi usi più comuni e compatibili, al ridimensionamento artistico vissuto dall’archeologia industriale grazie all’arte contemporanea ed al suo rapporto con la Modernità. In ultimo, si enuncia nel titolo il caso di studio, ovvero l’analisi della Fabbrica, che occupa il secondo capitolo. Si tratta di un enorme complesso industriale semi-abbandonato al confine con il centro storico, il cui protagonista è un grande gasometro, che l’autrice ha avuto modo di scoprire durante il suo soggiorno nella Città Eterna. Questo quartiere costituì il primo e unico moderno settore industriale della Roma moderna all’inizio del Novecento. Per diverse ragioni storiche e volontà politiche, la città praticamente non ha subito ulteriore sviluppo industriale oltre l’area citata, dove si impiantarono servizi e attività di grande trasformazione (Mattatoio, Mercati Generali, Magazzini Generali, Centrale Montemartini o questa fabbrica). Dal 1920, si inizió a costruire un tessuto prodottivo che portò la città dalla situazione post-bellica al miracolo economico. Di fronte al mito della Roma monumentale o della Roma quotidiana, appare questa Roma industriale come mito della contemporaneità. Tuttavia, questa città è troppo antica per diventare moderna, ed il suo processo industriale in contrasto con la sua lunga storia risulta breve. Il rapporto diretto della fase industriale romana con il risultato di questo sviluppo viene identificato con gli impianti segnalati, più significativi per la loro unicità che per la durata del momento irripetibile che rappresentano. La loro presenza fisica perdura nonostante l’abbandono, isolati dietro il loro muro di cinta e quasi sconosciuti. Questo li rende auspicabile per la speculazione immobiliare e sono un caso ideale per eseguire un Piano di Intervento Globale, che determini una serie di interventi necessari, usi compatibili e linee guida per la pianificazione del tutto, in linea con i concetti utilizzati nel primo capitolo.

Aprendiendo de Roma. Arquitectura de Colonizacion

Reflexiones sobre arquitectura derivadas de la participación en la Academia de España en Roma como pensionado de Arquitectura del curso académico 2009-2010

Geometría y Arquitectura en las iglesias cortesanas de Madrid en el siglo XVIII

Con la llegada al trono español de Felipe V, una pléyade de arquitectos y artistas italianos y franceses fueron llamados a Madrid por la nueva dinastía borbónica para cambiar el gusto artístico de un país de cultura y costumbres ajenas. De las obras que estos arquitectos dejaron en España, nos hemos centrado en la arquitectura religiosa por ser más evidente esta influencia. Hemos analizado dos iglesias madrileñas: la de San Ignacio y la Basílica Pontificia de San Miguel (antes iglesia de los santos Justo y Pastor).

Pinos y arte : ensayo de contextualización en la naturaleza desde el Paleolítico a Roma

Al ser la naturaleza objeto de representación artística por el hombre, campos tan diversos como el arte y la ciencia forestal pueden compartir sus orígenes. Los pinos son un género botánico repartido por la cuenca mediterránea capaces de suscitar emociones al haber sido sujetos de lo que fue una innovación cultural. Se propone que los pinos pudieron ser objeto de las primeras representaciones artísticas de los antiguos pobladores de la Península Ibérica. La metodología en la selección de resultados se basa en patrones morfológicos: patrón 1 (plántulas de pino en sus primeras etapas de crecimiento), patrón 2 (dibujos asimilables a ramas de pino) y patrón 3 (dibujos de pinos de gran porte). La presentación de los resultados se estructura en: parte I (referente a las representaciones artísticas estimadas como de pinos en la prehistoria, diferenciando el arte paleolítico del post-paleolítico), parte II (contempla los resultados encontrados en el repertorio iconográfico del arte Íbero y Celtíbero) y parte III (presenta una selección de resultados del arte romano en Hispania). Las diferentes etapas artísticas se articulan comenzando con una introducción, seguida de enfoques multidisciplinares que incluyen una visión histórica del paisaje o de la ecología de la vegetación. A continuación se exponen los resultados de la revisión realizada en cada etapa histórica y el estudio y descripción de las piezas seleccionadas (localización geográfica, datación arqueológica, clasificación genérica de técnica, materiales, dimensiones, iconografía, contexto cultural y procedencia) y por último su discusión en cuanto a su adscripción al género Pinus y a la flora presente en el entorno, caso de ser posible. Esta información se completa con gráficos, diagramas, mapas y tablas situándolas en su contexto arqueológico y cronológico, aportando datos sobre el carácter utilitario, simbólico o ideológico de los pinos, cuya pervivencia se manifiesta en ser protagonistas de gran número de festejos en la España rural de nuestros días. SUMMARY Nature has been represented in paintings since ancient times, which enables fields of study as separate as art and forest science to share a common origin. Pine-tress belong to a botanical genus widely distributed throughout the Mediterranean basin, which are capable of rising emotion and being a representation of what at that time was cultural innovation, subsequently becoming symbols. In this dissertation we hypothesise that pine forest may have been one of the first artistic representations of the ancient dwellers of the Iberian Peninsula. The methodology used for the selection of results is based on morphological patterns, i.e.: Patern 1 (pine seedlings at their first developmental stages), Pattern 2 (drawings associated with pine branches and shoots), and Pattern 3 (paintings of large pine-trees). Results are shown according to the following structure: Part I (relating to prehistoric paintings identified as pines and differentiating Paleolithic from Post-Paleolithic art), Part II (involves the results gathered concerning Iberian and Celtiberian iconographic art) and Part III (including a selection of Roman art in Hispania concerning pine representations). The different artistic periods are linked beginning by an Introduction, followed by a multidisciplinary approach ranging from a historical landscape analysis to plant ecology within a Mediterranean context. Thereafter, results are presented by assessing each historical period and by describing each of the particular art pieces subjected to investigation (geographical location, archaeological date, generic classification of the art technique, materials, dimensions, iconography and cultural context and origin). Finally, the results are discussed according to their ascription to the Pinus genus and when possible, in relation with the surrounding flora. The information provided is complemented with diagrams, maps and tables to enable its understanding within a chronological and archaeological context and providing evidence for the functional, symbolic and ideological character of pines, which are still alive in Spain in the form of many rural feasts with particular kinds of celebrations where this species plays a central role.

En ellos se tratan temas como el desarrollo local-regional y su articulación con la red de ciudades mundiales de la economía global. Un conjunto de estrategias territoriales son expuestas para afrontar la ordenación de las dinámicas metropolitanas actuales.

Documentación gráfica mediante fotogrametría digital de la cúpula del Pantheon en Roma

El trabajo presentado ofrece un ejemplo de aplicación de las nuevas tecnologías en el campo de la fotogrametría digital convergente aplicadas al levantamiento arquitectónico, práctica íntimamente conectada al análisis constructivo de edificios. La posibilidad de trabajar con herramientas informáticas de alto potencial pero de fácil utilización que no necesitan instrumentos de alta precisión ni el trabajo conjunto de varios operadores, permite realizar levantamientos indirectos de objetos complejos con cierta sencillez. En este caso se ha elegido como modelo de estudio el intradós de la cúpula del Pantheon en Roma. La especial configuración geométrica del interior de la cúpula permite un fácil reconocimiento de puntos de una imagen a la otra y por ello un control adecuado de los proyectos de restitución mediante fotogrametría. La presencia de los casetones que tiene a nivel perceptivo una fundamental importancia para poder reconstruir mentalmente la forma esférica de la superficie y su enorme tamaño sirve al mismo tiempo como característica de gran eficiencia en este trabajo de restitución. Los datos obtenidos mediante fotogrametría se han utilizado para elaborar una documentación gráfica del intradós de la cúpula y su forma empleando herramientas informáticas de dibujo vectorial que han permitido el estudio y cálculo promediado de los resultados.
