Design methodology of piezoelectric energy-harvesting skin using topology optimization

Abstract This paper describes a design methodology for piezoelectric energy harvester s that thinly encapsulate the mechanical devices and expl oit resonances from higher- order vibrational modes. The direction of polarization determines the sign of the pi ezoelectric tensor to avoid cancellations of electric fields from opposite polarizations in the same circuit. The resultant modified equations of state are solved by finite element method (FEM). Com- bining this method with the solid isotropic material with penalization (SIMP) method for piezoelectric material, we have developed an optimization methodology that optimizes the piezoelectric material layout and polarization direc- tion. Updating the density function of the SIMP method is performed based on sensitivity analysis, the sequen- tial linear programming on the early stage of the opti- mization, and the phase field method on the latter stage

Product placement e libertà di espressione

Object of the search is the advertising phenomenon of the "product placement", with reference to that it has been investigated legality’s limits, as well as the relationship with the constitutionally protected liberty of expression. Particularly, it has been analyzed, in first place, the problem of the relationship between the freedom of expression and the liberty of economic initiative, with particular reference to the different circles of guardianship to these prepared: or, larger, the one provided for the first from the 21th article of Costitution, more circumscribed, instead, the one established in the 41th article of Costitution, with reference to the second. This analysis has been made with the purpose to investigate the coordination among such liberties in those forms of communications that, for the proper peculiarities that characterize them, can be qualified, according to the concrete circumstances in which they are spread, so much forms of liberty of expression, how much exercise of an activity of enterprise. Under this last profile, it has been taken attention on the advertising activity and, specially, on the non transparent publicities, or not immediately perceivable as such from their receivers, and, therefore, in contrast with the advertising trasparence’s principle: or, the so-called cases of hidden publicity, what the editorial publicity, both "in narrow sense" both "in general sense", as well as the phenomenon of the product placement (or positioning of product), by now diffused in the commercial routine. Therefore, it has been proceeded to a complete and exhaustive examination of innovations introduced by the recent legislative discipline in subject of “planned placement of marks and products” in the cinema works, appraising, in the specific one, the effects, juridical and no juridical, consequential from the introduction of a first form of regulation of the phenomenon of the product placement and, particularly, from the express provision about the legality of the use to such advertising, if it has realized according to specific requirements or condition. In relationship to such profile, it has been also investigate limits (sub kind of normative gaps) from which the recently introduced discipline in subject would seem characterized. Finally, a further circle of investigation has concerned the possible organization of the phenomenon under a negotiate aspect, as particular contract of advertising, in which the object consists in an promotional activity. Concerning this, the experience of foreign countries (above all the Anglo-Saxon one) has been very important, because of the absence, in our arrangement, of a general normative discipline about advertising contracts. Consequently, I’ve investigated principal characteristics of similar contracts, in first place the atypicalness, because of the lack, in Italy, of a legislative discipline of this contract. Such investigation has also been developed through a comparation between the positioning of product and the other advertising contracts, among which, particularly, the sponsorship, as well as the contracts for the advertising exploitation of the name and other people's image, and, specially, the contract of testimonial and the contract of endorsement.

Development of quantitative methods for sustainability assessment in process industry

The increasing aversion to technological risks of the society requires the development of inherently safer and environmentally friendlier processes, besides assuring the economic competitiveness of the industrial activities. The different forms of impact (e.g. environmental, economic and societal) are frequently characterized by conflicting reduction strategies and must be holistically taken into account in order to identify the optimal solutions in process design. Though the literature reports an extensive discussion of strategies and specific principles, quantitative assessment tools are required to identify the marginal improvements in alternative design options, to allow the trade-off among contradictory aspects and to prevent the “risk shift”. In the present work a set of integrated quantitative tools for design assessment (i.e. design support system) was developed. The tools were specifically dedicated to the implementation of sustainability and inherent safety in process and plant design activities, with respect to chemical and industrial processes in which substances dangerous for humans and environment are used or stored. The tools were mainly devoted to the application in the stages of “conceptual” and “basic design”, when the project is still open to changes (due to the large number of degrees of freedom) which may comprise of strategies to improve sustainability and inherent safety. The set of developed tools includes different phases of the design activities, all through the lifecycle of a project (inventories, process flow diagrams, preliminary plant lay-out plans). The development of such tools gives a substantial contribution to fill the present gap in the availability of sound supports for implementing safety and sustainability in early phases of process design. The proposed decision support system was based on the development of a set of leading key performance indicators (KPIs), which ensure the assessment of economic, societal and environmental impacts of a process (i.e. sustainability profile). The KPIs were based on impact models (also complex), but are easy and swift in the practical application. Their full evaluation is possible also starting from the limited data available during early process design. Innovative reference criteria were developed to compare and aggregate the KPIs on the basis of the actual sitespecific impact burden and the sustainability policy. Particular attention was devoted to the development of reliable criteria and tools for the assessment of inherent safety in different stages of the project lifecycle. The assessment follows an innovative approach in the analysis of inherent safety, based on both the calculation of the expected consequences of potential accidents and the evaluation of the hazards related to equipment. The methodology overrides several problems present in the previous methods proposed for quantitative inherent safety assessment (use of arbitrary indexes, subjective judgement, build-in assumptions, etc.). A specific procedure was defined for the assessment of the hazards related to the formations of undesired substances in chemical systems undergoing “out of control” conditions. In the assessment of layout plans, “ad hoc” tools were developed to account for the hazard of domino escalations and the safety economics. The effectiveness and value of the tools were demonstrated by the application to a large number of case studies concerning different kinds of design activities (choice of materials, design of the process, of the plant, of the layout) and different types of processes/plants (chemical industry, storage facilities, waste disposal). An experimental survey (analysis of the thermal stability of isomers of nitrobenzaldehyde) provided the input data necessary to demonstrate the method for inherent safety assessment of materials.

Tracce di cinefilia su Facebook

La mia tesi approfondisce le dinamiche della cinefilia su Facebook: quali relazioni s'instaurano tra lo spettatore cinefilo, e dunque il suo particolare sguardo, e la moltitudine di frammenti di cinema dispersi nella rete; come si sono modificati i rapporti, gli atteggiamenti, i processi di negoziazione, le abitudini e soprattutto i discorsi dei cinefili al cospetto di tracce di cinema sui social network e in particolare su Facebook. Inoltreprovo a dimostrare che la cinefilia è un'esperienza costitutivamente autobiografica, cui il web permette il perpetuare potenzialmente infinito della (auto)narrazione di sé.

Schriftlicher Text im Film und seine Übersetzung : die Inserts der BBC-Serie Sherlock (2010-12) ; aus der Perspektive von Untertiteltheorie, Comictheorie und Translationspraxis

Die BBC-Serie SHERLOCK war 2011 eine der meistexportierten Fernsehproduktionen Großbritanniens und wurde weltweit in viele Sprachen übersetzt. Eine der Herausforderungen bei der Übersetzung stellen die Schrifteinblendungen der Serie (kurz: Inserts) dar. Die Inserts versprachlichen die Gedanken des Protagonisten, bilden schriftliche und digitale Kommunikation ab und zeichnen sich dabei durch ihre visuelle Auffälligkeit und teilweise als einzige Träger sprachlicher Kommunikation aus, womit sie zum wichtigen ästhetischen und narrativen Mittel in der Serie werden. Interessanterweise sind in der Übersetztung alle stilistischen Eigenschaften der Original-Inserts erhalten. In dieser Arbeit wird einerseits untersucht, wie Schrifteinblendungen im Film theoretisch beschrieben werden können, und andererseits, was sie in der Praxis so übersetzt werden können, wie es in der deutschen Version von Sherlock geschah. Zur theoretischen Beschreibung werden zunächst die Schrifteinblendungen in Sherlock Untertitelungsnormen anhand relevanter grundlegender semiotischer Dimensionen gegenübergestellt. Weiterhin wird das Verhältnis zwischen Schrifteinblendungen und Filmbild erkundet. Dazu wird geprüft, wie gut verschiedene Beschreibungsansätze zu Text-Bild-Verhältnissen aus der Sprachwissenschaft, Comicforschung, Übersetzungswissenschaft und Typografie die Einblendungen in Sherlock erklären können. Im praktischen Teil wird die Übersetzung der Einblendungen beleuchtet. Der Übersetzungsprozess bei der deutschen Version wird auf Grundlage eines Experteninterviews mit dem Synchronautor der Serie rekonstruiert, der auch für die Formulierung der Inserts zuständig war. Abschließend werden spezifische Übersetzungsprobleme der Inserts aus der zweiten Staffel von SHERLOCK diskutiert. Es zeigt sich, dass Untertitelungsnormen zur Beschreibung von Inserts nicht geeignet sind, da sie in Dimensionen wie Position, grafische Gestaltung, Animation, Soundeffekte, aber auch Timing stark eingeschränkt sind. Dies lässt sich durch das historisch geprägte Verständnis von Untertiteln erklären, die als möglichst wenig störendes Beiwerk zum fertigen Filmbild und -ablauf (notgedrungen) hinzugefügt werden, wohingegen für die Inserts in SHERLOCK teilweise sogar ein zentraler Platz in der Bild- und Szenenkomposition bereits bei den Dreharbeiten vorgesehen wurde. In Bezug auf Text-Bild-Verhältnisse zeigen sich die größten Parallelen zu Ansätzen aus der Comicforschung, da auch dort schriftliche Texte im Bild eingebettet sind anstatt andersherum. Allerdings sind auch diese Ansätze zur Beschreibung von Bewegung und Ton unzureichend. Die Erkundung der Erklärungsreichweite weiterer vielversprechender Konzepte, wie Interface und Usability, bleibt ein Ziel für künftige Studien. Aus dem Experteninterview lässt sich schließen, dass die Übersetzung von Inserts ein neues, noch unstandardisiertes Verfahren ist, in dem idiosynkratische praktische Lösungen zur sprachübergreifenden Kommunikation zwischen verschiedenen Prozessbeteiligten zum Einsatz kommen. Bei hochqualitative Produktionen zeigt ist auch für die ersetzende Insertübersetzung der Einsatz von Grafikern unerlässlich, zumindest für die Erstellung neuer Inserts als Übersetzungen von gefilmtem Text (Display). Hierbei sind die theoretisch möglichen Synergien zwischen Sprach- und Bildexperten noch nicht voll ausgeschöpft. Zudem zeigt sich Optimierungspotential mit Blick auf die Bereitstellung von sorgfältiger Dokumentation zur ausgangssprachlichen Version. Diese wäre als Referenzmaterial für die Übersetzung insbesondere auch für Zwecke der internationalen Qualitätssicherung relevant. Die übersetzten Inserts in der deutschen Version weisen insgesamt eine sehr hohe Qualität auf. Übersetzungsprobleme ergeben sich für das genretypische Element der Codes, die wegen ihrer Kompaktheit und multiplen Bezügen zum Film eine Herausforderung darstellen. Neben weiteren bekannten Übersetzungsproblemen wie intertextuellen Bezügen und Realia stellt sich immer wieder die Frage, wieviel der im Original dargestellten Insert- und Displaytexte übersetzt werden müssen. Aus Gründen der visuellen Konsistenz wurden neue Inserts zur Übersetzung von Displays notwendig. Außerdem stellt sich die Frage insbesondere bei Fülltexten. Sie dienen der Repräsentation von Text und der Erweiterung der Grenzen der fiktiv dargestellten Welt, sind allerdings mit hohem Übersetzungsaufwand bei minimaler Bedeutung für die Handlung verbunden.

Embedding Spatial Software Visualization in the IDE: an Exploratory Study

Software visualization can be of great use for understanding and exploring a software system in an intuitive manner. Spatial representation of software is a promising approach of increasing interest. However, little is known about how developers interact with spatial visualizations that are embedded in the IDE. In this paper, we present a pilot study that explores the use of Software Cartography for program comprehension of an unknown system. We investigated whether developers establish a spatial memory of the system, whether clustering by topic offers a sound base layout, and how developers interact with maps. We report our results in the form of observations, hypotheses, and implications. Key findings are a) that developers made good use of the map to inspect search results and call graphs, and b) that developers found the base layout surprising and often confusing. We conclude with concrete advice for the design of embedded software maps

National Identity in Lithuania: Processes During the Period of Changes

Under the conditions of rapid and total change in the social, political, economic and legal environment in Lithuania, a re-orientation process is going on in all groups of society. In this process, not only younger but also middle-aged and old people become adherents to what Ms. Liubiniene calls the new, "post-materialist" values, strongly reinforced by powerful agents of socialisation originating in the West, like the media, advertising agencies and lifestyle-consumption models. As a result, the national identity of Lithuania and its inhabitants is being reconstructed. Ms. Liubiniene set out to examine the details of this evolving identity by conducting a survey of 1218 university staff and students. Her conclusions are set out in a 74 page manuscript, written in Lithuanian and available on disc. Change is most noticeable among the young. Indeed, time and time again, Ms. Liubiniene was to find that the age of 36 marks a natural watershed, with, for instance, the younger group valuing individualism highly and the older, collectivism. Ms. Liubiniene ventures to suggest that traditional values are deeply rooted amongst elderly people, women and people with an education in the humanities. Young people on the other hand, and especially those with a professional orientation towards business are more open to change and ready to adapt to new values. Turning to the evaluation of national symbols, Ms. Liubinie finds that those with an education in the humanities might be considered to be the most traditional, placing greater value on the symbols of nature, ethnic culture and religion. Folk songs and the crucifix are also in their top ten. Respondents with a technical education favour symbols of statehood and nature, and respondents with a business orientation assign greater value to the symbols of nature, history, sports and statehood. Ms. Liubinie concludes that the group of respondents most active and ready to adapt to new things is composed of young males of a business orientation. Generally the national identity of the young is weaker compared to that of the old. In the future, the combination of the evolution of values and the process of inter-generational replacement allows us to predict a weakening of the sense of national identity, or at least its transformation into something radically different to what it is today.

The ArgoNeuT detector in the NuMI low-energy beam line at Fermilab

The ArgoNeuT liquid argon time projection chamber has collected thousands of neutrino and anti-neutrino events during an extended run period in the NuMI beam-line at Fermilab. This paper focuses on the main aspects of the detector layout and related technical features, including the cryogenic equipment, time projection chamber, read-out electronics, and off-line data treatment. The detector commissioning phase, physics run, and first neutrino event displays are also reported. The characterization of the main working parameters of the detector during data-taking, the ionization electron drift velocity and lifetime in liquid argon, as obtained from through-going muon data complete the present report.

How to Improve the Production Process for interactive TV with semi-formal Methods

The central question for this paper is how to improve the production process by closing the gap between industrial designers and software engineers of television(TV)-based User Interfaces (UI) in an industrial environment. Software engineers are highly interested whether one UI design can be converted into several fully functional UIs for TV products with different screen properties. The aim of the software engineers is to apply automatic layout and scaling in order to speed up and improve the production process. However, the question is whether a UI design lends itself for such automatic layout and scaling. This is investigated by analysing a prototype UI design done by industrial designers. In a first requirements study, industrial designers had created meta-annotations on top of their UI design in order to disclose their design rationale for discussions with software engineers. In a second study, five (out of ten) industrial designers assessed the potential of four different meta-annotation approaches. The question was which annotation method industrial designers would prefer and whether it could satisfy the technical requirements of the software engineering process. One main result is that the industrial designers preferred the method they were already familiar with, which therefore seems to be the most effective one although the main objective of automatic layout and scaling could still not be achieved.

Konstruktive Gestaltung eines bioinspirierten Kommissionier-Greifers für intralogistische Handhabungsaufgaben

In diesem Beitrag wird ein neuartiger biologisch inspirierter Universalgreifer beschrieben. Dieser soll in einem automatisierten Kommissionier-Szenario selbstständig Waren aus Kisten greifen, anheben und an anderer Stelle ablegen um somit das manuelle Kommissionieren von Hand zu substituieren. Auf dem Weg zu einer ausgereiften Konstruktion werden zahlreiche Fragestellungen zur Gestaltung und Anordnung der Finger und deren Antrieb gelöst. Ein für diesen Anwendungsfall entwickelter Biegeaktor wird zur Krümmung der Finger eingesetzt und bietet als Alleinstellungsmerkmal ein nahezu verschleißfreies Gelenk bei einem sehr einfachen konstruktiven Aufbau.

Using the Journalistic Metaphor to Design User Interfaces That Explain Sensor Data

Facilitating general access to data from sensor networks (including traffic, hydrology and other domains) increases their utility. In this paper we argue that the journalistic metaphor can be effectively used to automatically generate multimedia presentations that help non-expert users analyze and understand sensor data. The journalistic layout and style are familiar to most users. Furthermore, the journalistic approach of ordering information from most general to most specific helps users obtain a high-level understanding while providing them the freedom to choose the depth of analysis to which they want to go. We describe the general characteristics and architectural requirements for an interactive intelligent user interface for exploring sensor data that uses the journalistic metaphor. We also describe our experience in developing this interface in real-world domains (e.g., hydrology).

La arquitectura residencial en El Real Sitio de El Pardo (1885 - 1965): Orígenes, tipos y configuración del trazado urbano

Tras la denominación de Real Sitio a mediados del siglo XVIII, bajo el reinado de Fernando VI, su sucesor Carlos III procedió a la incorporación a su Patrimonio de todos los Montes y Bosques de El Pardo. Comenzó entonces el proceso de planeamiento urbano y de construcción arquitectónica que finalizó en torno al año 1800. En lo sucesivo, no sólo se mantiene el curso de la conservación y consolidación de los edificios principales, sino que se realiza obra nueva de índole civil. Algunos edificios cambiaron de propiedad y de uso hasta que tras la Guerra Civil se procedió a la mayor transformación vivida por el Real Sitio. El intervalo que aquí se trata (1885 a 1965), no ha suscitado, en los estudios sobre El Pardo, atención suficiente al no acontecer obra nueva de carácter patrimonial ni ha sido objeto de análisis el trazado y la fisonomía del centro urbano residencial del pueblo que Carlos III configuró. Sin embargo se estima relevante analizar los cambios en la actividad residencial; en primer lugar porque coexiste con la arquitectura oficial y, por tanto, se entiende necesario un análisis global del conjunto y en segundo lugar porque facilita la comprensión sobre la imagen original de carácter histórico del conjunto de finales del siglo XVIII. Este marco temporal determina tres partes principales de estudio que estructuran la presente tesis, cuyas fechas establecen los intervalos históricos clave: Actuaciones sobre el núcleo urbano consolidado (1885-1931). Cese de la actividad constructiva (1931-1939). Propuestas regeneradoras y crecimiento acelerado (1939-1965). Dentro de ellos se establecen, a su vez, dos subcapítulos diferenciados con la finalidad de explicar los sucesos que pautaron los cambios trascendentales en la historia de El Pardo. En el estudio del estado de la cuestión se observa que en El Pardo, al igual que sucede en otros Reales Sitios, se investigan los edificios destacados como el Palacio, la Casita del Príncipe, la Casa de Oficios y la Casa de Infantes desde el punto de vista de su historia pero no desde la arquitectura ni de cómo esta afecta al desarrollo del trazado y por tanto al contexto urbano. Se manifiestan determinadas carencias de tratamiento gráfico que facilitarían la comprensión histórica mediante el análisis de la forma y cómo esta ha ido variando sustancialmente. El concepto de escala y orientación reordena el estudio, no sólo de estos edificios protagonistas sino de los que se entretejen a su alrededor y componen el conjunto histórico, lo cual aporta nuevas conclusiones al estado de la cuestión que aquí compete. El principal objetivo de la tesis es, por tanto, contribuir a la dimensión patrimonial mediante el estudio de la arquitectura residencial del pueblo de El Pardo y en cómo esta ha ido conformando y consolidando el entramado urbano original en torno a edificios de la realeza y corte. Analizar aquellos edificios que perduran, los que fueron reconstruidos, rehabilitados, y apuntar acontecimientos históricos que formularon la actual fisonomía. Sistematizar y reordenar sobre la traza actual los edificios que desaparecieron, nos da las pistas sobre las modificaciones en concepto de escala arquitectónica y urbana. El estudio de las fuentes y establecer una metodología de conexión de estas, ayuda a detectar dónde no se han dirigido aún los focos de interés así como las lagunas que han quedado por explorar con el fin de responder a nuevas hipótesis, conceder conclusiones y abrir otras líneas de investigación. Como conclusiones generales, la tesis aporta documentación nueva sobre el objeto de estudio, no solicitada, digitalizada o publicada con anterioridad. En ella se analizan los procesos de configuración, consolidación y transformación en el Real Sitio mediante la sistematización de estados comparativos. Con respecto al estudio de los diferentes contextos natural y urbano la tesis analiza cómo los accidentes naturales, el desarrollo de infraestructuras y el impulso de la agronomía afectaron a El Pardo a partir del siglo XIX, y estudia los procesos de configuración, consolidación y transformación en el Real Sitio mediante la sistematización de la documentación encontrada de manera gráfica y escrita. En relación al marco patrimonial arquitectónico, la tesis analiza los procesos edificatorios históricos. Se estudian, a su vez, cambios de ocupación o uso que derivaron en reformas, ampliaciones, obras de nueva planta e incluso en derribos, así como los proyectos no materializados o que se llevaron a cabo de manera parcial. Con respecto al análisis del momento histórico, la tesis analiza las posibles afectaciones, políticas, sociales y económicas en las etapas de Monarquía, Segunda República, Guerra Civil y Posguerra. Por último, la tesis abre cuatro vías de investigación (que ya se han tratado y avanzado en parte pero que escapan a los límites de este trabajo) que pueden plantear nuevas hipótesis, reportando así respuestas sobre objetos de estudio complementarios y paralelos al presente. Estas refieren a análisis más concretos sobre El Palacio Real de El Pardo y la Casa de Oficios, el Camino Real de Madrid a El Pardo desde la Puerta de Hierro, los cuarteles, puertas y portilleras del Monte de El Pardo y los proyectos desarrollados por el arquitecto Diego Méndez en los Reales Sitios para el Patrimonio Nacional. ABSTRACT Following the Royal Site denomination being granted in the mid-18th Century, during the reign of Ferdinand VI, his successor Charles III proceeded to include all the Forests and Woodlands of El Pardo in his heritage. That then gave rise to the process of town planning and architectural construction that was completed around 1800. Thereafter, not only the process of conservation and consolidation of the main buildings has been maintained, but new civil engineering works have also been carried out. Some buildings changed ownership and use until, after the Civil War, the greatest transformation experienced by the Royal Site was undertaken. The time frame this paper concerns (1885 to 1965), has not attracted sufficient attention in studies of El Pardo due to there having been no new works with heritage status, nor has there been an analysis of the layout and external appearance of the residential centre in the town once conceived by Charles III. However, it is considered relevant to analyse the changes in residential activity, firstly, because it coexists with the official architecture and, thus, it is considered necessary to perform a global analysis of the complex and, secondly, because it facilitates a historical understanding of the original appearance of the complex at the end of the 18th Century. This time framework defines three main parts of the study that provide the structure of this thesis, the dates of which establish the key historical time frames: Actions in the consolidated town centre (1885-1931). Cessation of construction works (1931-1939). Proposals of regeneration and accelerated growth (1939-1965). Two distinct sub-chapters are also established within these, in order to explain the events that marked the transcendental changes in the history of El Pardo. When studying the subject matter, it is noted that in El Pardo, as is the case in other Royal Sites, outstanding buildings such as the Palace, the Prince's Cottage, the Trades House and the Infantes House are usually researched strictly from the point of view of their history, but not from an architectural perspective, nor analysing how that affects the development of the site layout and thus the urban area. Specific shortcomings are evident in the graphic treatment that would have otherwise facilitated a historical understanding through the analysis of the shape and the way it has gradually undergone substantial variation. The concept of scale and orientation reorganises the study, not only of these key buildings, but also of those that are woven around them and make up the historic complex, allowing entirely new conclusions concerning the subject matter analysed herein. Therefore, the main purpose of this thesis is to outline our heritage through the study of the residential architecture of the town of El Pardo and the analysis of the way the original town has been built up and consolidated around the buildings erected by royalty and the court; to analyse the buildings that still remain, those that were rebuilt, refurbished, and to note historic events that shaped its current appearance. To this end, a systematic classification and reorganisation on the current urban layout of the buildings that have disappeared will give us the key to understand changes in the concept of architectural and urban scale. Studying the sources and establishing a methodology to connect them will help us detect those areas where the focus of interest has not concentrated yet, and will also reveal the gaps that remain unexplored, in order to respond to new hypotheses, reach new conclusions and open up new lines of research. As general conclusions, this thesis provides new documentation on the subject matter that had not been requested, digitized or published before. There we find an analysis of the processes of configuration, consolidation and transformation of the Royal Site through a systematic classification of comparative states. With regard to the study of the multiple natural and urban environments, this thesis analyses the way natural features, development of infrastructures and agricultural driving forces affected El Pardo as of the 19th Century, and it studies the processes of configuration, consolidation and transformation of the Royal Site by systematically classifying the documentation found in graphic and written documents. In relation to the architectural heritage framework, this thesis analyses historical building processes. Likewise, a study is also performed on the changes in land occupation or use that led to reforms, extensions, new buildings and even to demolitions, as well as on unrealized projects, or even on those that were partially implemented. As for the analysis of the historical time period, this thesis assesses the potential political, social and economic effects of the Monarchy, Second Republic, Civil War and Post-War Periods. Finally, this thesis opens up four lines of investigation (that have already been discussed and partially advanced, but which fall beyond the scope of this work) that could pose new hypotheses, thus giving answer to other subject matters parallel and complementary to the one assessed herein. These refer to more specific analyses of El Palacio Real de El Pardo (Royal Palace of El Pardo) and the Casa de Oficios (Trades House), the Royal Highway from Madrid to El Pardo from Puerta de Hierro, the barracks, gates and entrances to estates in the Woodlands of El Pardo and the projects developed on the Royal Sites by the architect Diego Méndez for the National Heritage.

Estudio de los principales CMS para la creación de una red social

Actualmente las redes sociales son muy utilizadas en todo el mundo, existen diferentes tipos de redes sociales con las que podemos conectar con amigos, ampliar nuestra red de contactos profesionales, aprender cosas nuevas, etc. Su elevado uso las ha convertido en uno de los negocios más rentables en internet generando fortunas para sus creadores, principalmente, a través de la publicidad. Muchas redes sociales son creadas por empresas que cuentan con un equipo experto, pero otras muchas han sido creadas por personas comunes, con bajos conocimientos informáticos, muchos motivados en sus aficiones o carreras profesionales, que al no encontrar nada en la red que les resulte útil, han decidido desarrollar ellos mismos sus propias redes sociales con la ayuda de herramientas informáticas. Una de esas herramientas son los sistemas de gestión de contenidos (CMS), con los cuales ahorraremos mucho tiempo de desarrollo y no necesitaremos invertir grandes cantidades de dinero. Este proyecto trata, principalmente, de cómo crear redes sociales haciendo uso de estas herramientas y tiene el objetivo de ser lo suficientemente claro para que cualquier persona, sin importar su nivel de conocimientos técnicos, sea capaz de desarrollar sus ideas. En la primera parte del proyecto se habla sobre las redes sociales en general y el impacto de éstas en la sociedad actual, donde se ve que, actualmente, debido a la cantidad de redes sociales y a la accesibilidad móvil, el uso de las redes sociales es una cotidianidad. También se explican algunos métodos para obtener beneficios económicos de una red social y las ventajas que presentan las redes sociales específicas frente a las generalistas, concluyendo que las redes sociales específicas van ganando mayor protagonismo con el paso del tiempo. Además, se habla sobre la crítica de las redes sociales desde el punto de vista del usuario de la red, donde se resalta el tema de la administración de la publicidad y la privatización que han supuesto las redes sociales. Posteriormente se presenta una base teórica sobre las herramientas antes mencionadas, los CMS. Se explica su funcionamiento, clasificación y las ventajas que obtenemos con el uso de este software en nuestros proyectos, de los cuales destacan el corto tiempo de desarrollo y el bajo coste. Al final se eligen los CMS de estudio en este proyecto principalmente en base a tres criterios: licencia, cuota de uso y características de red social. En la segunda parte del proyecto se habla acerca de los CMS elegidos: WordPress con su plugin BuddyPress, Elgg, y Joomla con su plugin JomSocial. Se explican las características de cada uno de ellos y se muestran ejemplos de redes sociales reales hechas con estos CMS. En esta parte del proyecto se hace un uso práctico de estos CMS y se detalla paso a paso todo el proceso de creación de una red social (instalación, configuración y personalización de la red social) para cada CMS. El resultado son tres redes sociales hechas con distintos CMS, de los cuales se hace una valoración en base a la experiencia obtenida con el uso de los mismos, concluyéndose que JomSocial es una buena opción para redes sociales de uso generalista, pero para redes específicas son mejores tanto Elgg como BuddyPress, presentando este último una ligera ventaja por tener una gran comunidad en español. ABSTRACT. Nowadays social networks are widely used throughout the world, there are different types of social networks where you can connect with friends, expand your network of professional contacts, learn new things, etc. Its high usage has turned them into one of the most profitable businesses on Internet generating fortunes to its developers, mainly through advertising. Many social networks are developed by companies that count on an expert team, but many others have been created by ordinary people, with low computer skills, many of them motivated in their hobbies or careers, that did not find anything useful on Internet and decide to develop their own social networks with the help of software tools. One of those tools is a content management system (CMS), which will help us to save a lot of development time and we will not need to invest large amounts of money. This project is, mainly, about how to create social networks using these tools and aims to be clear enough to help anyone, regardless of their computer skills, to develop their ideas. The first part of the project is about social networks in general and the impact on today's society, where we can see that, due to the number of social networks and mobile accessibility, the use of social networks is daily. Also it explains some ways to obtain economic benefits from a social network and the advantages of specific social networks against generalist social networks, concluding that specific social networks are gaining more prominence with the passage of time. In addition, it refers on social networks critique from the point of view of social network users, where it highlights the issue of the advertising administration and privatization which have brought social networks. Subsequently, it presents a theoretical base of the above mentioned tools, CMS. Explains their operation, classification and the advantages we get with the use of this software in our projects, where the short development time and lower cost are highlighted. At the end the CMS studied in this project are chosen mainly based on three criteria: license, community size and social network features. The second part of the project is about the chosen CMS: WordPress with its plugin BuddyPress, Elgg, and Joomla with its plugin JomSocial. It explains features of all of them and shows examples of real social networks developed with these CMS. This part of the project is a practical use of these CMS and detailed step by step throughout the process of creating a social network (installation, configuration and customization of the social network) for each CMS. The result are three social networks made with different CMS, from which is made an assessment on the basis of the experience gained with the use of these software, concluding that JomSocial is a good choice to develop generalist social networks, but for specific social networks are better Elgg and BuddyPress, presenting the latter a slight advantage by having a large community in Spanish.

Modelo para la integración del trazado de infraestructuras lineales en el paisaje y el medio ambiente basado en SIG

El análisis de las diferentes alternativas en la planificación y diseño de corredores y trazados de carreteras debe basarse en la correcta definición de variables territoriales que sirvan como criterios para la toma de decisión y esto requiere un análisis ambiental preliminar de esas variables de calidad. En España, los estudios de viabilidad de nuevas carreteras y autovías están asociados a una fase del proceso de decisión que se corresponde con el denominado Estudio Informativo, el cual establece condicionantes físicos, ambientales, de uso del suelo y culturales que deben ser considerados en las primeras fases de la definición del trazado de un corredor de carretera. Así, la metodología más frecuente es establecer diferentes niveles de capacidad de acogida del territorio en el área de estudio con el fin de resumir las variables territoriales en mapas temáticos y facilitar el proceso de trazado de las alternativas de corredores de carretera. El paisaje es un factor limitante a tener en cuenta en la planificación y diseño de carreteras y, por tanto, deben buscarse trazados más sostenibles en relación con criterios estéticos y ecológicos del mismo. Pero este factor no es frecuentemente analizado en los Estudios Informativos e incluso, si es considerado, los estudios específicos de la calidad del paisaje (estético y ecológico) y de las formas del terreno no incorporan las recomendaciones de las guías de trazado para evitar o reducir los impactos en el paisaje. Además, los mapas de paisaje que se generan en este tipo de estudios no se corresponden con la escala de desarrollo del Estudio Informativo (1:5.000). Otro déficit común en planificación de corredores y trazados de carreteras es que no se tiene en cuenta la conectividad del paisaje durante el proceso de diseño de la carretera para prevenir la afección a los corredores de fauna existentes en el paisaje. Este déficit puede originar un posterior efecto barrera en los movimientos dispersivos de la fauna y la fragmentación de sus hábitats debido a la ocupación parcial o total de las teselas de hábitats con importancia biológica para la fauna (o hábitats focales) y a la interrupción de los corredores de fauna que concentran esos movimientos dispersivos de la fauna entre teselas. El objetivo principal de esta tesis es mejorar el estudio del paisaje para prevenir su afección durante el proceso de trazado de carreteras, facilitar la conservación de los corredores de fauna (o pasillos verdes) y la localización de medidas preventivas y correctoras en términos de selección y cuantificación de factores de idoneidad a fin de reducir los impactos visuales y ecológicos en el paisaje a escala local. Concretamente, la incorporación de valores cuantitativos y bien justificados en el proceso de decisión permite incrementar la transparencia en el proceso de diseño de corredores y trazados de carreteras. Con este fin, se han planteado cuatro preguntas específicas en esta investigación (1) ¿Cómo se seleccionan y evalúan los factores territoriales limitantes para localizar una nueva carretera por los profesionales españoles de planificación del territorio en relación con el paisaje? (2) ¿Cómo pueden ser definidos los corredores de fauna a partir de factores del paisaje que influyen en los movimientos dispersivos de la fauna? (3) ¿Cómo pueden delimitarse y evaluarse los corredores de fauna incluyendo el comportamiento parcialmente errático en los movimientos dispersivos de la fauna y el efecto barrera de los elementos antrópicos a una escala local? (4) ¿Qué y cómo las recomendaciones de diseño de carreteras relacionadas con el paisaje y las formas del terreno pueden ser incluidas en un modelo de Sistemas de Información Geográfica (SIG) para ayudar a los ingenieros civiles durante el proceso de diseño de un trazado de carreteras bajo el punto de vista de la sostenibilidad?. Esta tesis doctoral propone nuevas metodologías que mejoran el análisis visual y ecológico del paisaje utilizando indicadores y modelos SIG para obtener alternativas de trazado que produzcan un menor impacto en el paisaje. Estas metodologías fueron probadas en un paisaje heterogéneo con una alta tasa de densidad de corzo (Capreolus capreolus L.), uno de los grandes mamíferos más atropellados en la red de carreteras españolas, y donde está planificada la construcción de una nueva autovía que atravesará la mitad del área de distribución del corzo. Inicialmente, se han analizado las variables utilizadas en 22 estudios de proyectos de planificación de corredores de carreteras promovidos por el Ministerio de Fomento entre 2006 y 2008. Estas variables se agruparon según condicionantes físicos, ambientales, de usos del suelo y culturales con el fin de comparar los valores asignados de capacidad de acogida del territorio a cada variable en los diferentes estudios revisados. Posteriormente, y como etapa previa de un análisis de conectividad, se construyó un mapa de resistencia de los movimientos dispersivos del corzo en base a la literatura y al juicio de expertos. Usando esta investigación como base, se le asignó un valor de resistencia a cada factor seleccionado para construir la matriz de resistencia, ponderándolo y combinándolo con el resto de factores usando el proceso analítico jerárquico y los operadores de lógica difusa como métodos de análisis multicriterio. Posteriormente, se diseñó una metodología SIG para delimitar claramente la extensión física de los corredores de fauna de acuerdo a un valor umbral de ancho geométrico mínimo, así como la existencia de múltiples potenciales conexiones entre cada par de teselas de hábitats presentes en el paisaje estudiado. Finalmente, se realizó un procesado de datos Light Detection and Ranging (LiDAR) y un modelo SIG para calcular la calidad del paisaje (estético y ecológico), las formas del terreno que presentan características similares para trazar una carretera y la acumulación de vistas de potenciales conductores y observadores de los alrededores de la nueva vía. Las principales contribuciones de esta investigación al conocimiento científico existente en el campo de la evaluación del impacto ambiental en relación al diseño de corredores y trazados de carreteras son cuatro. Primero, el análisis realizado de 22 Estudios Informativos de planificación de carreteras reveló que los métodos aplicados por los profesionales para la evaluación de la capacidad de acogida del territorio no fue suficientemente estandarizada, ya que había una falta de uniformidad en el uso de fuentes cartográficas y en las metodologías de evaluación de la capacidad de acogida del territorio, especialmente en el análisis de la calidad del paisaje estético y ecológico. Segundo, el análisis realizado en esta tesis destaca la importancia de los métodos multicriterio para estructurar, combinar y validar factores que limitan los movimientos dispersivos de la fauna en el análisis de conectividad. Tercero, los modelos SIG desarrollados Generador de alternativas de corredores o Generator of Alternative Corridors (GAC) y Eliminador de Corredores Estrechos o Narrow Corridor Eraser (NCE) pueden ser aplicados sistemáticamente y sobre una base científica en análisis de conectividad como una mejora de las herramientas existentes para la comprensión el paisaje como una red compuesta por nodos y enlaces interconectados. Así, ejecutando los modelos GAC y NCE de forma iterativa, pueden obtenerse corredores alternativos con similar probabilidad de ser utilizados por la fauna y sin que éstos presenten cuellos de botella. Cuarto, el caso de estudio llevado a cabo de prediseño de corredores y trazado de una nueva autovía ha sido novedoso incluyendo una clasificación semisupervisada de las formas del terreno, filtrando una nube de puntos LiDAR e incluyendo la nueva geometría 3D de la carretera en el Modelo Digital de Superficie (MDS). El uso combinado del procesamiento de datos LiDAR y de índices y clasificaciones geomorfológicas puede ayudar a los responsables encargados en la toma de decisiones a evaluar qué alternativas de trazado causan el menor impacto en el paisaje, proporciona una visión global de los juicios de valor más aplicados y, en conclusión, define qué medidas de integración paisajística correctoras deben aplicarse y dónde. ABSTRACT The assessment of different alternatives in road-corridor planning and layout design must be based on a number of well-defined territorial variables that serve as decision-making criteria, and this requires a high-quality preliminary environmental analysis of those quality variables. In Spain, feasibility studies for new roads and motorways are associated to a phase of the decision procedure which corresponds with the one known as the Informative Study, which establishes the physical, environmental, land-use and cultural constraints to be considered in the early stages of defining road corridor layouts. The most common methodology is to establish different levels of Territorial Carrying Capacity (TCC) in the study area in order to summarize the territorial variables on thematic maps and facilitate the tracing process of road-corridor layout alternatives. Landscape is a constraint factor that must be considered in road planning and design, and the most sustainable layouts should be sought based on aesthetic and ecological criteria. However this factor is not often analyzed in Informative Studies and even if it is, baseline studies on landscape quality (aesthetic and ecological) and landforms do not usually include the recommendations of road tracing guides designed to avoid or reduce impacts on the landscape. The resolution of the landscape maps produced in this type of studies does not comply with the recommended road design scale (1:5,000) in the regulations for the Informative Study procedure. Another common shortcoming in road planning is that landscape ecological connectivity is not considered during road design in order to avoid affecting wildlife corridors in the landscape. In the prior road planning stage, this issue could lead to a major barrier effect for fauna dispersal movements and to the fragmentation of their habitat due to the partial or total occupation of habitat patches of biological importance for the fauna (or focal habitats), and the interruption of wildlife corridors that concentrate fauna dispersal movements between patches. The main goal of this dissertation is to improve the study of the landscape and prevent negative effects during the road tracing process, and facilitate the preservation of wildlife corridors (or green ways) and the location of preventive and corrective measures by selecting and quantifying suitability factors to reduce visual and ecological landscape impacts at a local scale. Specifically the incorporation of quantitative and well-supported values in the decision-making process provides increased transparency in the road corridors and layouts design process. Four specific questions were raised in this research: (1) How are territorial constraints selected and evaluated in terms of landscape by Spanish land-planning practitioners before locating a new road? (2) How can wildlife corridors be defined based on the landscape factors influencing the dispersal movements of fauna? (3) How can wildlife corridors be delimited and assessed to include the partially erratic movements of fauna and the barrier effect of the anthropic elements at a local scale? (4) How recommendations of road design related to landscape and landforms can be included in a Geographic Information System (GIS) model to aid civil engineers during the road layout design process and support sustainable development? This doctoral thesis proposes new methodologies that improve the assessment of the visual and ecological landscape character using indicators and GIS models to obtain road layout alternatives with a lower impact on the landscape. These methodologies were tested on a case study of a heterogeneous landscape with a high density of roe deer (Capreolus capreolus L.) –one of the large mammals most commonly hit by vehicles on the Spanish road network– and where a new motorway is planned to pass through the middle of their distribution area. We explored the variables used in 22 road-corridor planning projects sponsored by the Ministry of Public Works between 2006 and 2008. These variables were grouped into physical, environmental, land-use and cultural constraints for the purpose of comparing the TCC values assigned to each variable in the various studies reviewed. As a prior stage in a connectivity analysis, a map of resistance to roe deer dispersal movements was created based on the literature and experts judgment. Using this research as a base, each factor selected to build the matrix was assigned a resistance value and weighted and combined with the rest of the factors using the analytic hierarchy process (AHP) and fuzzy logic operators as multicriteria assessment (MCA) methods. A GIS methodology was designed to clearly delimit the physical area of wildlife corridors according to a geometric threshold width value, and the multiple potential connections between each pair of habitat patches in the landscape. A Digital Surface Model Light Detection and Ranging (LiDAR) dataset processing and a GIS model was performed to determine landscape quality (aesthetic and ecological) and landforms with similar characteristics for the road layout, and the cumulative viewshed of potential drivers and observers in the area surrounding the new motorway. The main contributions of this research to current scientific knowledge in the field of environmental impact assessment for road corridors and layouts design are four. First, the analysis of 22 Informative Studies on road planning revealed that the methods applied by practitioners for assessing the TCC were not sufficiently standardized due to the lack of uniformity in the cartographic information sources and the TCC valuation methodologies, especially in the analysis of the aesthetic and ecological quality of the landscape. Second, the analysis in this dissertation highlights the importance of multicriteria methods to structure, combine and validate factors that constrain wildlife dispersal movements in the connectivity analysis. Third, the “Generator of Alternative Corridors (GAC)” and “Narrow Corridor Eraser (NCE)” GIS models developed can be applied systematically and on a scientific basis in connectivity analyses to improve existing tools and understand landscape as a network composed of interconnected nodes and links. Thus, alternative corridors with similar probability of use by fauna and without bottlenecks can be obtained by iteratively running GAC and NCE models. Fourth, our case study of new motorway corridors and layouts design innovatively included semi-supervised classification of landforms, filtering of LiDAR point clouds and new 3D road geometry on the Digital Surface Model (DSM). The combined used of LiDAR data processing and geomorphological indices and classifications can help decision-makers assess which road layouts produce lower impacts on the landscape, provide an overall insight into the most commonly applied value judgments, and in conclusion, define which corrective measures should be applied in terms of landscaping, and where.
