  1. Diseño arquitectónico centrado en el usuario mediante neurotecnologías inmersivas

    LÓPEZ-TARRUELLA MALDONADO, JUAN
    The architectural design process is a highly complex task based on crystallizing a unique solution which will satisfy simultaneously a series of requirements of a very diverse nature. In order to meet the technical requirements, the architect is guided by objective criteria based on empirical science, which guarantees the appropriateness of the proposed solutions. Nevertheless, some other more subjective aspects or factors in accordance with the client's particular preferences and demands, such as functionality or aesthetic effect, are usually tackled in a personal and intuitive manner by the project designer. This procedure does not allow the architect to know the client's subjective...

  2. THE DEVELOPMENT OF GREEN-BUILDING PROJECTS: OPTIMIZATION OF THE PROJECT-MANAGEMENT PROCESSES THROUGH THE LEAN APPROACH.

    ORSI, ALESSANDRO
    As the world becomes aware of its limited resources it is increasingly important to consider the development of buildings which could respond to the requirements of sustainability. During the last decades the development of the so-called green buildings has been gaining momentum through the implementation of appropriate reference standards, new technologies, innovative design strategies and processes. Such changes introduced new challenges for all subjects involved and, most of all, the need of working with new technologies and services through fully-integrated processes. Designers are also affected by such issue and, within this scope, project management plays a key role for the...

  3. Comportamiento termomecánico de pilotes prefabricados

    GROOT VIANA, MARIA DE
    This thesis follows the development of the PITERM project (Thermo-mechanical characterization and new design techniques of geothermal piles) within the Spanish INNPACTO 2011 program, a public-private cooperation funded by our Ministry of Science and Innovation. This project was the first to aim at a fully integrated analysis of the combined effect of mechanical and thermal actions upon a newly designed precast pile, thermally activated and fully instrumented. The project started in September 2011 and lasted until December 2013. The overall goal of this project was to analyse the behaviour of thermo-active foundations in order to further develop-relevant design methodologies for these...

  4. HÍBRIDOS FOTOGRÁFICOS EN EL ARTE CONTEMPORÁNEO. Un estudio para su conservación

    MONTOLIO DEBÓN, MARÍA PILAR
    Since the birth of photography, at the end of the nineteenth century, there has been much progress in the field of this 'new' technique. It is a delicate means which in a subtle way managed to become an additional artistic category of fine arts. Its ability to be hybrid and fuse with different elements gave photography the opportunity to create new artistic genres through the hand of great artists. It has been, and continues to be, used as a vehicle and material for all those who use it to provide evidence of their existence, especially in conceptual art, where artworks...

  5. A political economy approach to measuring EU food standard enforcement and their implications on agri-food trade.

    TAGHOUTI, IBTISSEM
    The effect of Non-Tariff Measures (NTMs) on agri-food trade has drawn broad research interest and gained a substantial attention by scientific community as well as by policy makers. Sanitary and Phytosanitary (SPS) standards among others represent a major challenge for trade policy and food safety. The identification and measurement of the economic implications of NTMs require the use of an adequate both methodological and empirical framework to derive sound estimates. By targeting economic sectors and issues not previously investigated, this Thesis contributes to previous literature on determining the factors that affect the implementation of SPS and their effects on trade...

  6. Different strategies to obtain antimicrobial biodegradable films for food applications, using starch and/or chitosan with or without essential oils

    VALENCIA SULLCA, CRISTINA ENCARNACIÓN
    El desarrollo de materiales de envase biodegradables activos es uno de los retos de la sociedad para resolver los problemas medioambientales asociados a los residuos plásticos y mejorar la conservación de los alimentos, alargando su vida útil.

  7. Diseño de alimentos lácteos con capacidad saciante. Relación entre estructura, procesamiento oral y percepción

    MORELL ESTEVE, PERE
    This thesis studies how to increase the expected satiating ability in dairy products analyzing the effect of the incorporation of certain ingredients. The study of food reformulation with high expected satiating ability contributes to moderate size meal choice and to regulate food intake. In this thesis, two factors influencing the satiating ability perception of semi-solid foods have been mainly studied: a) the increase in oral processing time that produces prolonged orosensory signals, and b) the increase in protein content. The increase in oral processing time is produced by, for example, higher consistencies, mouth-coating or creaminess sensations. These features can be modified...

As the title of the thesis indicates, this is based on the study of the forms of production (staging) of scenic actions that bring life to the stage. Our thesis have two parts. The first one is a theoretical analysis on theatre and the forms of action in relation to the subject. Here we introduce references of artistic and theoretical proposals that are related or have influenced our artistic production, analyzed in the second part of the thesis. In the second part...

  9. Testing-Based Conceptual Schema Validation in a Model-Driven Environment

    Granda Juca, María Fernanda
    Despite much scepticism and problems for its adoption, the Model-Driven Development (MDD) is being used and improved to provide many inherent benefits for industry. One of its greatest benefits is the ability to handle the complexity of software development by raising the abstraction level. Models are expressed using concepts that are not related to a specific implementation technology (e.g. Unified Modelling Language -UML, Object Constraint Language -OCL, Action Language for Foundational UML -ALF), which means that the models can be easier to specify, maintain and document. As in Model-Driven Engineering (MDE), the primary artefacts are the conceptual models, efforts are...

  10. gestUI: a model-driven method for including gesture-based interaction in user interfaces

    Parra González, Luis Otto
    The research reported and discussed in this thesis represents a novel approach to define custom gestures and to include gesture-based interaction in user interfaces of the software systems with the aim of help to solve the problems found in the related literature about the development of gesture-based user interfaces. The research is conducted according to Design Science methodology that is based on the design and investigation of artefacts in a context. In this thesis, the new artefact is the model-driven method to include gesture-based interaction in user interfaces. This methodology considers two cycles: the main cycle is an engineering cycle where...

  11. Haciendo/creando el aprendizaje del Oboe: Aplicación experimental de la improvisación y la creación en la clase de Música de Cámara y de Conjunto en el conservatorio. Acciones Estratégicas (2014-2017)

    COTOLÍ MIGUEL, MARÍA VICENTA
    Building/creating the learning of the oboe: Experimental implementation of improvisation and creation in Chamber Music and Group Music in a conservatory. Strategic Actions (2014-2017) An oboe's class in the music conservatory can be summed up in the practicing of the studies and of the instrument's own repertoire. In order to future oboists are able to perform scores along their life, this is the way required technique and musicality are addressed. However, we have noticed a far too large number of students who cannot find motivation in that way of approaching the class. Low performance, lack of motivation and premature abandonment are very...

  12. The combination of the disciplines of Techmining and semantic TRIZ for better and faster analyzing technology evolution

    Vicente Gomila, José Miguel
    The purpose of the present thesis is to explore and to demonstrate how the combination of two methodological approaches, text mining plus the systemic vision of TRIZ empowered by semantics, can bring a larger and more comprehensive analysis of the evolution of a technology. Both approaches had been not combined before the first of the four papers constituents of the present thesis based in a compendium of publications. However, this combination applied to the evolution of technologies is increasingly being published in the scientific literature. Such combination shows a second benefit in the form of an improvement in accessing and...

  13. La taxonomía iconogràfica. Proposta de classificació i nomenclatura de les imatges reproductibles

    MAYNÉS TOLOSA, PAU
    This multidisciplinary study has investigated the terminology used to name reproductible images in the context of cultural heritage. With the help of various disciplines such as lexicography, materials science, systematics or the technical history of photography, we analysed the misuse often made of the terminology and made a proposal for the classification of techniques of printmaking, photography, photomechanical printing and electronic printing according to criteria that includes the principle of image formation, the manufacturing technology and the materials composing the objects. This classification, called "iconographic taxonomy" allows to deduce correct terminology and expressions made to designate such images. We can call this naming technique systematic terminology. In conclusion is a...

  14. ANÁLISIS DE ACTUACIÓN PARA LA CONSERVACIÓN DE GRAFITIS Y PINTURA MURAL EN AEROSOL. ESTUDIO DEL STRAPPO COMO MEDIDA DE SALVAGUARDA.

    AMOR GARCÍA, RITA LUCÍA
    Graf ti and street art are two young artistic and expressive manifestations present - both directly or indirectly - in the day-to-day life of almost anyone. Beyond their initial categorization as vandalistic expressions far from the perception of an organized society, graf ti and street art have transformed the conception of mural art and regained its importance again in the public environment. Despite the rejection that these practices have suffered for years - due to the illegal condition of their actions -, many people do not pay attention to those particularities, and focus on what the artworks have to offer...

  15. FOTOGRAFÍA Y TIEMPO. LA TEMPORALIDAD CONTENIDA EN LA FOTOGRAFÍA CONCEPTUAL A PARTIR DE LOS '90

    GARCIA MARTINEZ, FRANCISCO MIGUEL
    Time inevitably adheres to photography, from the early catches over eight hours of exposure to the most fleeting snapshots. The existence of this time raises questions about its nature, its different manifestations, and their way to affecting both photography and its reception by the audience. This research work focuses on the theoretical study and practical development of temporality in photography, especially attending three aspects: how is the picture captured, how is shown to the viewer, and what is shown on it. The study begins with the analysis of initial discussions on photography, whether its objective or subjective, its treatment as snapshot...

  16. Films activos para el envasado de alimentos a base de ácido Poliláctico (PLA) y almidón

    Muller, Justine
    Biodegradable active films based on poly(lactic) acid (PLA) and starch were developed and characterized as to their functional and structural properties, using the bilayer film strategy, in order to obtain materials that better meet the food packaging requirements. Plasticization of semicrystalline PLA was analysed by using three different biodegradable compounds to enhance the PLA mechanical performance. Likewise, cinnamaldehyde was incorporated to PLA-starch bilayer films and their antimicrobial properties and release kinetics in food simulants were analysed. Semicrystalline and amorphous PLA and cassava starch (S) were used to obtain the films. Semicrystalline PLA and S were processed by melt blending and...

    Bataller Prats, Román
    I begin this PhD thesis with an introductory chapter about electronic nose systems, where I describe the sensor system types, electronic nose types and the chemometric and measurement techniques employed in the development of the thesis. Next, I define the general and specific objectives of the thesis. In the following chapters I discuss the different aspects of the measuring device and the journal articles that served as motivation for its design. The first article is based on the proof of concept of the humid electronic nose prototype, whose design relies on the performance of voltammetric measurements. An array of four metallic working...

  18. Proposal for a LCA improvement roadmap in the Agri-food sector based on information exchange requirements and the enclosed data in recent LCAs works

    OLIVEIRA BARROS, FILIPE MARINHO
    Innovation is essential to promote human progress and to improve the humans' quality of life, but it should be done in a social and environmental context and in accordance with the principles of sustainable development. To achieve this challenge the environmental innovation guidelines should be taken into account. In this line, it is necessary to analyze the life cycle assessment (LCA) of any product, process or service and compute its environmental impacts. Despite the rapid evolution of environmental methods and tools and the increase of sustainability studies in recent years, LCA remains an area that still has to face major development...

  19. Corrosión de cuerdas de instrumentos musicales. Influencia en el comportamiento acústico

    LÓPEZ MUELAS, JOSÉ LUIS
    In this work we have evaluated the corrosion state of steel guitar strings produced by a synthetic solution of human sweat. It has been reproduced for three assumptions. First, without any system of protection against corrosion. Second, incorporating the cathodic protection of the strings by means of sacrificial anodes. And third, by subjecting the strings to a cathodic protection system by impresed current. A structure can be protected against corrosion by attaching it to a lower ionization energy metal, which will act as an anode in front of it, corroding itself while protecting it. This is the basic idea of cathodic...

  20. Metodología espacio-temporal con datos de panel. Estudio de la mortalidad europea.

    CARRACEDO GARNATEO, PATRICIA
    In recent years, the mortality gap between Eastern and Western European countries is increasing. For this reason, several studies have recently been applied to analyze the differences in European mortality. In order to detect similar mortality groups, there is an urgent need to extend the current studies with spatial studies, which take into account the geographical location of countries, time and their interaction. This doctoral thesis aims to help public policies so that they can efficiently distribute resources, as well as actuaries, who develop life insurance and design pension plans. In this context, three main objectives are proposed. The first one...
