A novel context ontology to facilitate interoperation of semantic services in environments with wearable devices

The LifeWear-Mobilized Lifestyle with Wearables (Lifewear) project attempts to create Ambient Intelligence (AmI) ecosystems by composing personalized services based on the user information, environmental conditions and reasoning outputs. Two of the most important benefits over traditional environments are 1) take advantage of wearable devices to get user information in a nonintrusive way and 2) integrate this information with other intelligent services and environmental sensors. This paper proposes a new ontology composed by the integration of users and services information, for semantically representing this information. Using an Enterprise Service Bus, this ontology is integrated in a semantic middleware to provide context-aware personalized and semantically annotated services, with discovery, composition and orchestration tasks. We show how these services support a real scenario proposed in the Lifewear project.

On a meaningful integration of web services in data-intensive biomedical environments: The DICODE approach

This paper reports on an innovative approach that aims to reduce information management costs in data-intensive and cognitively-complex biomedical environments. Recognizing the importance of prominent high-performance computing paradigms and large data processing technologies as well as collaboration support systems to remedy data-intensive issues, it adopts a hybrid approach by building on the synergy of these technologies. The proposed approach provides innovative Web-based workbenches that integrate and orchestrate a set of interoperable services that reduce the data-intensiveness and complexity overload at critical decision points to a manageable level, thus permitting stakeholders to be more productive and concentrate on creative activities.

Contribution to Load-Frequency Regulation of a Hydropower Plant with Long Tail-Race Tunnel

In this paper, a hydroelectric power plant with long tail-race tunnel has been modelled for assessing its contribution to secondary regulation reserve. Cavitation problems, caused by the discharge conduit length, are expected downstream the turbine where low pressure appears during regulation manoeuvres. Therefore, governor's gains should be selected taking into account these phenomena. On the other hand, regulation services bidden by the plant operator should fulfil TSO (Transmission System Operator) quality requirements. A methodology for tuning governor PI gains is proposed and applied to a Hydro power plant in pre-design phase in northwest area of Spain. The PI gains adjustment proposed provides a proper plant response, according to some established indexes, while avoiding cavitation phenomena.

Planar compact array with parasitic elements for MIMO systems

A compact planar array with parasitic elements is studied to be used in MIMO systems. Classical compact arrays suffer from high coupling which makes correlation and matching efficiency to be worse. A proper matching network improves these lacks although its bandwidth is low and may increase the antenna size. The proposed antenna makes use of parasitic elements to improve both correlation and efficiency. A specific software based on MoM has been developed to analyze radiating structures with several feed points. The array is optimized through a Genetic Algorithm to determine parasitic elements position in order to fulfill different figures of merit. The proposed design provides the required correlation and matching efficiency to have a good performance over a significant bandwidth.

Expectations from EMET and OESEE ground listening of possible EM events generated by the TSS 1R

On 22nd February '96, the space mission STS 75 started ,from the NASA facilities at Cape Canaveral. Such a mission consists in the launch of the shuttle Columbia in order to carry out two experiments in the space: the TSS 1R (Tethered Satellite Sistem 1 Refliight) and the USMP (United States Microgravity Payload). The TSS 1R is a replica of a similar mission TSS 1 '92. The TSS space programme is a bilateral scientific cooperation between the USA space agency NASA (National Aeronautics and Space Agency) and the ASI (Italian Space Agency. The TSS 1R system consists on the shuttle Columbia which deploys, up-ward, by means a conducting tether 20 km long, a spherical satellite (1.5 mt diameter) containing scientific instrumentation. This system, orbiting at about 300 km from the Earth's surface, represents, presently, the largest experimental space structure, Due to its dimensions, flexibility and conducting properties of the tether, the system interacts, in a quite complex manner, wih the earth magnetic field and the ionospheric plasma, in a way that the total system behaves as an electromagnetic radiating antenna as well as an electric power generator. Twelve scientific experiments have been assessed by US and Italian scientists in order to study the electro dynamic behaviour of the structure orbiting in the ionos phere. Two experiments have been prepared in the attempt to receive on the Earth's surface possible electromagnetic events radiated by the TSS 1R. The project EMET (Electro Magnetic Emissions from Tether),USA and the project OESEE (Observations on the Earth Surface of Electromagnetic Emissions) Italy, consist in a coordinated programme of passive detection of such possible EM emissions. This detection will supply the verification of some thoretical hypotheses on the electrodynamic interactions between the orbiting system, the Earth's magnetic field and the ionospheric plasma with two principal aims as the technological assesment of the system concept as well as a deeper knowledge of the ionosphere properties for future space applications. A theoretical model that keeps the peculiarities of tether emissionsis being developed for signal prediction at constant tether current. As a step previous to the calculation of the expected ground signal , the Alfven-wave signature left by the tether far back in the ionosphere has been determined. The scientific expectations from the combined effort to measure the entity of those perturbations will be outlined taking in to account the used ground track sensor systems.

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 censura del tema deportivo en la prensa durante la posguerra española (1939-1945)

La presente tesis doctoral pretende arrojar nueva luz sobre la utilización de la prensa durante los primeros años del franquismo. En concreto, el objetivo ha sido estudiar la censura del tema deportivo dentro del sistema censorio de los primeros años de posguerra civil en España, una área no estudiada hasta hoy y que entendemos fundamental para entender el desarrollo del deporte durante el llamado primer franquismo. Para ello, se estudiaron de manera pormenorizada los actores principales y los pasos básicos del proceso de censura; los métodos utilizados, tanto materiales como personales, para hacer efectiva ésta; y, por último, sus manifestaciones reales en el ámbito de la información deportiva: qué se censuró, por parte de quién, de qué forma y por qué motivos. De este modo, pretendemos llenar una de las lagunas de investigación que aún quedan dentro del estudio de la censura de prensa durante el franquismo. La metodología utilizada es la técnica historiográfica. Basado en el análisis crítico y en la interpretación de fuentes primarias, dicho método trata de establecer marcos históricos de referencia a través del estudio pormenorizado de las circunstancias del pasado. Ello implica una estructura algo distinta a la de las tesis doctorales de otras áreas de estudio puesto que, exceptuando la introducción, toda la tesis es la exposición de los resultados de la investigación llevada a cabo. Se ha utilizado cuantiosa documentación de los archivos General de la Administracion (Alcalá de Henares) y Centrale dello Stato (Roma) no manejada anteriormente por ningún investigador. La prensa periódica de la época y la legislación que afecta a nuestro tema de estudio también han sido ampliamente investigadas, tanto en el contexto español como en el italiano. Nuestra investigación arroja los siguientes resultados. Efectivamente, existió censura de prensa en el tema deportivo en las siguientes temáticas fundamentales: cuestiones económicas, autoridades y jerarquías, uso del lenguaje y comportamiento de los deportistas. En la mayor parte de los casos, la censura se ejerce en la información deportiva por razones ajenas al propio deporte. No se puede afirmar que existan diferencias en el tratamiento general entre medios de la Prensa del Movimiento y otros de titularidad privada o eclesiástica, si bien la aplicación de la censura no fue homogénea sino arbitraria en muchos casos. El sistema de censura de prensa español del primer franquismo toma la mayoría de sus rasgos del modelo fascista italiano, aunque tiene alguna característica propia como la censura previa y el catolicismo imperante. ABSTRACT This doctoral thesis aims to shed light on the use of press during the first years of francoism. The particular objective was to study the censorship of the sport topic into the general system of censorship carried out after the Spanish Civil War. It is a subject comparatively understudied to date but a key aspect to understand the development of sport during the so called early francoism. To this end, an in-depth study was made on key actors, main steps of censorship process, human and material methods used to ensure its effectiveness, and the actual manifestations in sports information area: what was censored, by whom, how and why. This should ensure us to fill the historiographical gap within the research on Francoʼs press censorship. Methodology used was historiographic research. It is based on critical analysis and interpretation of primary sources and seeks to establish historical reference frameworks tracing back the past in detail. It determines a different doctoral thesis structure in some aspects. Except the introduction, the whole document is the report and explanation of the results of research. A large amount of unexplored documents from the Archivo General de la Administración (Alcalá de Henares, Spain) and the Archivio Centrale dello Stato (Rome, Italy) has been used. The press of the period and legislation about our topic have also been analysed in detail both in Spain and Italy. Our research states these results. We can affirm that press censorship actually existed on sports topic in these thematic priorities: economical issues, authorities and hierarchies, use of language and sportsmen behaviours. In most cases, the censorship of sports information is exercised for reasons unconnected to sport. It cannot be concluded that general differences were applied in press censorship between State-owned media and private or church media although its implementation was non-uniform and arbitrary in many cases. The system of press censorship in Spain during the early francoism is clearly inspired by fascist Italy system copying most of its features although Spain had a few specific characteristics like prior censorship and catholicism.

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.

Monitor sísmico interactivo

Este trabajo tiene como objetivos la monitorización en tiempo real de la actividad sísmica, tanto próxima como lejana, a partir de los datos sísmicos registrados por una estación de banda ancha, y el desarrollo de un sistema de difusión interactiva de información actualizada de terremotos, destinado al público general. Ambas fuentes de información se mostrarán a través de una Unidad de Visualización denominada “Monitor Sísmico Interactivo”. El registro de los datos sísmicos se realiza utilizando el sensor de tres componentes de la estación sísmica GUD, perteneciente a la Red Digital de Banda Ancha y transmisión digital del Instituto Geográfico Nacional, instalada en la Basílica del Valle de los Caídos, en lalocalidad de Guadarrama (Madrid). En la E.T.S.I. Topografía, Geodesia y Cartografía se ha instalado un ordenador con conexión a Internet, para la recepción y almacenamiento de los datos, y los programas Scream y Drumplot desarrollados por Guralp, necesarios para la monitorización de la señal sísmica en tiempo real. A partir de estos datos, mediante aplicaciones desarrolladas bajo programación Linux y haciendo uso de las herramientas que ofrece el software SAC (Seismic Analysis Code), se genera además un registro gráfico y una película animada de dicha segmentación para cada evento. Se ha configurado un servidor de correo y una cuenta para la recepción de dos tipos de mensajes de correo, enviados desde la sede central del Instituto Geográfico Nacional, con la información de los eventos registrados por GUD una vez revisados: - Mensajes enviados diariamente, con un listado de eventos ocurridos en los 30 últimos días. - Mensajes con la información en cuasi tiempo real de la última alerta sísmica. Se ha desarrollado el programa “saco” para la gestión del correo recibido que analiza la información sísmica, la almacena en ficheros y ejecuta sobre ellos las aplicaciones de dibujo. Estas aplicaciones han sido previamente desarrolladas bajo programación Linux y software GMT (Generic Mapping Tools), y a partir de ellas se generan automáticamente las distintas imágenes que se visualizan en el Monitor Sísmico: un mapa de sismicidad próxima en la Península Ibérica, un mapa de sismicidad lejana en el mundo, un mapa de detalle para localizar y representar la última alerta generada, los listados con la información de los eventos representados en los mapas, los registros gráficos y las películas animadas de dichos sismogramas. Monitor Sísmico Interactivo ha sido desarrollado para ofrecer además la posibilidad de interactuar con la Unidad de Visualización: se ha creado una base de datos para uso científico donde se almacenan todos los eventos registrados por GUD. Así el usuario puede realizar una petición, a través del envío de un mensaje de correo, que le permite visualizar de forma instantánea las imágenes que muestran la información de cualquier terremoto de su interés. ABSTRACT This study is aimed at real-time monitoring of both near and distant seismic activityfrom the seismic data recorded by a broadband seismic station, and the development of an interactive broadcast system of updated information of earthquakes, for the general public. Bothsources of information are displayed through a display unit called "Interactive Seismic Monitor". The seismic data recording is carried out by using the three-component sensor of the GUD seismic station, which belongs to the Digital Network Broadband and digital broadcast of the National Geographic Institute, housed in the Basilica of The Valley of the Fallen, in the town of Guadarrama (Madrid). A computer with Internet connection has been installed in E.T.S.I. Surveying, Geodesy and Cartography for receiving and storing data, together with Scream and Drumplot programs, developed by Guralp, which are necessary for monitoring the real time seismic signal. Based on the data collected, through programming applications developed under Linux system and using the software tools provided by the SAC (Seismic Analysis Code), a chart recorder and an animated gif image of the segmentation for each event are also generated. A mail server and a mail account have been configured for the receipt of two types of email messages, sent from the National Geographic Institute head office, with the information of the events recorded by GUD after being reviewed: - Messages sent daily, providing a list of events in the past 30 days. - Messages containing information on near real-time seismic of the last seismic alert. A program called "saco" has also been developed for handling mail received that analyzes the seismic data, which stores it in files and runs drawing applications on them. These applications have been previously developed under Linux system and software programming GMT (Generic Mapping Tools), and from them different images that are displayed on the Seismic Monitor are automatically generated: a near seismicity Iberian peninsula map, a distant seismicity world map, a detailed map to locate and represent the last seismic alert generated, the lists with the information of the events depicted in the maps,together with the charts and the animated gif image of such seismograms. Interactive Seismic Monitor has been developed to offer any user the possibility of interacting with the display unit: a database has been created for scientific use which stores all the events recorded by GUD. Thus, any user could make a request, by sending an e-mail that allows them to view instantly all the images showing the information of any earthquake of interest on the display unit.

La luz natural como generadora del espacio arquitectónico de la catedral gótica

La historia de la construcción de las catedrales góticas es la historia de la búsqueda de la luz. Esta afirmación casi metafísica, recoge una realidad asumida por todos los historiadores tanto de la arquitectura antigua como del resto de las artes. La luz en el gótico ha sido descrita bajo múltiples matices como son su carácter simbólico, cromático e incluso místico, sin embargo no existe, en el estudio del conocimiento de la luz gótica, ninguna referencia a la misma como realidad física cuantificable, cualificable y por tanto, clasificable. La presente tesis doctoral aborda el concepto de la iluminación gótica desde una perspectiva nueva. Demuestra, con un método analítico inédito, que la iluminación gótica es cuantificable y cualificable. Para ello analiza en profundidad la iluminación de una selección de 6 edificios muestra, las catedrales de Gerona, Toledo, Sevilla y León, la basílica de Santa María del Mar y la capilla de la Sainte Chapelle de París, mediante una toma de datos “in situ” de iluminación y su comparación con los datos lumínicos obtenidos por un programa de soleamiento de la simulación en tres dimensiones de los distintos proyectos originales góticos. El análisis exhaustivo de las muestras y su introducción en el método analítico descrito, permite determinar, en primer lugar, unas cualidades inéditas que identifican la luz de los espacios góticos según unos parámetros nuevos como son la intensidad, expresividad, recorrido, distorsión y color. También describe cuales son los factores determinantes, de nuevo inéditos, que modulan cada una de las cualidades y en que proporción lo hacen cada uno de ellos. Una vez establecidas las cualidades y los factores que las definen, la tesis doctoral establece los rangos en los que se mueven las distintas cualidades y que conformarán la definitiva clasificación según “tipos de cualidad lumínica”. Adicionalmente, la tesis propone un procedimiento abreviado de acercamiento a la realidad de la iluminación gótica a través de unas fórmulas matemáticas que relacionan los factores geométricos detectados y descritos en la tesis con el resultado luminoso del espacio en lo que concierne a las dos cualidades más importantes de las reflejadas, la intensidad y la expresividad. Gracias a este método y su procedimiento abreviado, la clasificación se hace extensible al resto de catedrales góticas del panorama español y europeo y abre el camino a nuevas clasificaciones de edificios históricos de distintas épocas, iniciando un apasionante camino por recorrer en la recuperación de “la luz original”. Esta clasificación y sus cualidades podrán a su vez, ser utilizadas como herramientas de conocimiento de un factor determinante a la hora de describir cualquier espacio gótico y su aportación pretende ser un nuevo condicionante a tener en cuenta en el futuro, ayudando a entender y respetar, en las posibles intervenciones a realizar sobre el patrimonio arquitectónico, aquello que fue en su inicio motor principal del proyecto arquitectónico y que hoy día no se valora suficientemente tan solo por falta de conocimiento: su luz. The history of the construction of the Gothic cathedrals is the history of the search for light. This almost etaphysical statement reflects a reality accepted by all historians both of ancient architecture and other arts. Light in the Gothic period has been described under multiple approaches such as its symbolic, chromatic and even mystical character. However, in the study of the Gothic light, no references exist to it as a physical quantifiable and qualifiable reality and therefore, classifiable. This dissertation deals with the concept of Gothic light from a new perspective. With a new analytical method, it shows that Gothic lighting is quantifiable and can be classified regarding quality. To this end, a selection of 6 buildings light samples are analyzed; the cathedrals of Gerona, Toledo, Seville and León, the basilica of Santa María of the Sea and the Sainte Chapelle in Paris. "In situ" lighting data is collected and it is compared with lighting data obtained by a program of sunlight of the 3D simulation of various Gothic original projects. The comprehensive analysis of the samples and the data introduced in the analytical method described, allows determining, first, important qualities that identify the light of Gothic spaces according to new parameters such as intensity, expressiveness, trajectory, distortion and color. It also describes the determinant factors, which modulate each of the qualities and in what proportion they do it. Once the qualities and factors that define them have been established, in this doctoral dissertation the ranges regarding different qualities are set, which will make up the final classification according to "types of light quality". In addition, this work proposes an abbreviated procedure approach to the reality of the Gothic lighting through some mathematical formulae, relating the geometric factors identified and described in the study with the bright result of space regarding the two most important qualities of the light,intensity and expressiveness. Thanks to this method and to the abbreviated procedure, the classification can be applied to other Spanish and European Gothic cathedrals and opens up the way to new classifications of historic buildings from different eras, starting an exciting road ahead in the recovery of the "original light". This classification and its qualities may in turn be used as tools to know a determinant factor when describing any Gothic space. Its contribution is intended to be a new conditioning factor to keep in mind in the future, helping to understand and respect, in possible interventions on the architectural heritage, what was the main engine to start the architectural project and which today is not valued enough due to the lack knowledge: the light.

Structural Analysis of Thin Tile Vaults and Domes: The Inner Oval Dome of the Basilica de los Desamparados in Valencia

The inner oval dome of the Basílica de la Virgen los Desamparados, built in 1701, is one of the most slender masonry vaults ever built. It is a tile dome with a total thickness of 80 mm and a main span of 18.50 m. It was built without centering with great ingenuity and economy of means, thirty three years after the termination of the building in 1667. The dome is in contact with the external dome only in the inferior part with the projecting ribs of the intrados, the lunettes of the windows, and, in the upper part, through 126 inclined iron bars. This unique construction was revealed in the 1990's in the studies previous to the restoration of the Basílica, and has given rise to different theories about the mode of construction and the structural behaviour and safety of the dome. The present contribution aims to provide a plausible hypothesis about the mode of construction and to explain the safety of the inner dome which has stood, without need of repairs or reinforcement, for 300 hundred years.

New data on the Pleistocene of Trani (Adriatic Coast, Southern Italy)

Along the Apulian Adriatic coast, in a cliff south of Trani, a succession of three units (superimposed on one another) of marine and/or paralic environments has been recognised. The lowest unit I is characterised by calcareous/siliciclastic sands (css), micritic limestones (ml), stromatolitic and characean boundstones (scb), characean calcarenites (cc). The sedimentary environment merges from shallow marine, with low energy and temporary episodes of subaerial exposure, to lagoonal with a few exchanges with the sea. The lagoonal stromatolites (scb subunit) grew during a long period of relative stability of a high sea level in tropical climate. The unit I is truncated at the top by an erosion surface on which the unit II overlies; this consists of a basal pebble lag (bpl), silicicla - stic sands (ss), calcareous sands (cs), characean boundstones (cb), brown paleosol (bp). The sedimentary environment varies from beach to lagoon with salinity variations. Although there are indications of seismic events within the subunits cs, unit II deposition took place in a context of relative stability. The unit II is referable to a sea level highstand. Unit III, trangressive on the preceding, consists of white calcareous sands (wcs), calcareous sands and calcarenites (csc), phytoclastic calcirudite and phytohermal travertine (pcpt), mixed deposits (csl, m, k, c), sands (s) and red/brown paleosols (rbp). The sedimentation of this unit was affected by synsedimentary tectonic, attested by seismites found at several heights. Also the unit III is referable to a sea level highstand. The scientific literature has so far generally attributed to the Tyrrhenian (auct.) the deposits of Trani cliff. As part of this work some datings were performed on 10 samples, using the amino acid racemization method (AAR) applied to ostracod carapaces. Four of these samples have been rejected because they have shown in laboratory recent contamination. The numerical ages indicate that the deposits of the Trani cliff are older than MIS 5. The upper part of the unit I has been dated to 355±85 ka BP, thus allowing to assign the lowest stromatolitic subunit (scb) at the MIS 11 peak and the top of the unit I at the MIS 11-MIS 10 interval. The base of the unit II has been dated to 333±118 ka BP, thus attributing the erosion surface that bounds the units I and II to the MIS 10 lowstand and the lower part of the unit II to MIS 9.3. The upper part of the unit II has been dated to 234±35 ka BP, while three other numerical ages come from unit III: 303±35, 267±51, 247±61 ka BP. At present, the numerical ages cannot distinguish the sedimentation ages of units II and III, which are both related to the MIS 9.3- MIS 7.1 time range. However, the position of the units, superimposed one another, and their respective age, allows us to recognise a subsidence phase between MIS 11 and MIS 7, followed by an uplift phase between the MIS 7 and the present day, which led the deposits in their current position. This tectonic pattern is not in full agreement with what is described in the literature for the Apulian foreland.

Origin of the gases released from the Acqua Passante and Ermeta wells (Mt. Amiata, central Italy) and possible environmental implications for their closure

The Mt. Amiata volcano (Tuscany, central Italy) hosts the second largest geothermal field of Italy. Its SW and NE sectors are characterized by the presence of several CO2-rich (mayor que95% by vol.) gas discharges. An intense Hg mining activity had taken place from the 19th century up to the end of the ?70s, particularly close to Abbadia San Salvatore, during which two drillings (Acqua Passante and Ermeta) intercepted a CO2-rich gas fertile horizon. The related gases are emitted in the atmosphere since 1938 and 1959, respectively, causing severe concerns for the local air quality. In this work the results of a geochemical and isotopic survey carried out on these gas emissions from March 2009 to January 2014 are presented. CO2 fluxes from both the two wells and soil from an area of about 653,500 m2 located between them were measured. The two wells are emitting up to 15,000, 92 and 8 tons y-1 of CO2, CH4 and H2S, respectively, while the computed soil CO2 output was estimated at 4,311 ton y-1. The spatial distribution of the CO2 soil flux suggests the presence of preferential patterns, indicating sites of higher permeability. Since the local municipality is evaluating the possibility to plug the Ermeta vent, a temporarily closure should first be carried out to test the possible influence of this operation on the diffuse soil degassing of deep-originated CO2 in the surrounding area. This implies that diffuse soil gases should carefully be monitored before proceeding with its definitive closure.
