Estudio de la funcionalización de secciones eficaces de celda en multigrupos para cálculos best-estimate 3D pin-by-pin de núcleos PWR

Uno de los objetivos del Proyecto europeo NURISP (NUclear Reactor Integrated Platform) del 7º Programa Marco es avanzar en la simulación de reactores de agua ligera mediante el acoplamiento de códigos best-estimate que profundicen en la física de núcleo, termohidráulica bifásica y comportamiento del combustible [1]. Uno de estos códigos es COBAYA3, código de difusión 3D en multigrupos pin-by-pin desarrollado en la UPM, que requiere de librerías de secciones eficaces homogeneizadas a nivel de la barrita de combustible.

The future obligations of "project manager" as construction integral director (DIPE) in the law of buildings construction in spain (LOE)

In the year 1999 approves the Law of Construction Building (LOE, in Spanish) to regulate a sector such as construction, which contained some shortcomings from the legal point of view. Currently, the LOE has been in force 12 years, changing the spanish world of the construction, due to influenced by internationalization. Within the LOE, there regulating the different actors involved in the construction building, as the Projects design, the Director of Construction, the developer, The builder, Director of execution of the construction (actor only in Spain, similar as construcion engineer and abroad in), control entities and the users, but lacks figure Project manager will assume the delegation of the promoter helping and you organize, direct and management the process. This figure assumes that the market and contracts are not legally regulated in Spain, then should define and establish its regulation in the LOE. (Spain Construction Law) The translation in spanish of the words "Project Manager is owed to Professor Rafael de Heredia in his book Integrated Project Management, as agent acting on behalf of the organization and promoter assuming control of the project, ie Integraded Project Management . Already exist in Spain, AEDIP (Spanish Association Integrated of Project Construction management) which comprises the major companies in “Project Management” in Spain, and MeDIP (Master in Integrated Construction Project) the largest and most advanced studies at the Polytechnic University of Madrid, in "Construction Project Management" they teach which is also in Argentina. The Integrated Project ("Project Management") applied to the construction process is a methodological technique that helps to organize, control and manage the resources of the promoters in the building process. When resources are limited (which is usually most situations) to manage them efficiently becomes very important. Well, we find that in this situation, the resources are not only limited, but it is limited, so a comprehensive control and monitoring of them becomes not only important if not crucial. The alternative of starting from scratch with a team that specializes in developing these follow directly intervening to ensure that scarce resources are used in the best possible way requires the use of a specific methodology (Manual DIP, Matrix Foreign EDR breakdown structure EDP Project, Risk Management and Control, Design Management, et ..), that is the methodology used by "Projects managers" to ensure that the initial objectives of the promoters or investors are met and all actors in process, from design to construction company have the mind aim of the project will do, trying to get their interests do not prevail over the interests of the project. Among the agents listed in the building process, "Project Management" or DIPE (Director Comprehensive building process, a proposed name for possible incorporation into the LOE, ) currently not listed as such in the LOE (Act on Construction Planning ), one of the agents that exist within the building process is not regulated from the legal point of view, no obligations, ie, as is required by law to have a project, a builder, a construction management, etc. DIPE only one who wants to hire you as have been advanced knowledge of their services by the clients they have been hiring these agents, there being no legal obligation as mentioned above, then the market is dictating its ruling on this new figure, as if it were necessary, he was not hired and eventually disappeared from the building process. As the aim of this article is regular the process and implement the name of DIPE in the Spanish Law of buildings construction (LOE)

Intereses exógenos y resistencia ciudadana en la transformación físicosocial de un asentamiento auto-producido de Dakar (2005-2011)

La presión sobre el acceso a la tierra en la península de Dakar, Senegal, ha generado un proceso de transformación físico-social del mayor asentamiento auto-producido de la periferia urbana de Dakar (Pikine Irregular Sur) en el periodo 2005-2011. Esta investigación se propone analizar en qué medida las acciones llevadas a cabo: i) satisfacen o no el sistema integral de necesidades de los afectados (Demanda); ii) favorecen la implicación de los afectados o, por el contrario, fortalecen las estructuras de poder dominantes (Oferta), y iii) promueven o no la autonomía económica, la sostenibilidad ambiental, la equidad social y la legitimidad de los actores que participan (Entorno). La investigación se ha llevado a cabo por el método de estudio de casos, mediante un proceso de recogida de información participativo, articulado de abajo hacia arriba, en el que han participado 196 personas; la información recogida se ha procesado mediante la utilización de dos herramientas de análisis de realidades complejas: flujo de programa y sistema funcional. Los resultados del estudio de los casos 1 y 2 muestran que las acciones se han llevado a cabo en beneficio de los intereses de los mercados y de los actores que toman las decisiones y gestionan los recursos, incrementando la dependencia económica, empobreciendo a los directamente afectados y fragmentando su tejido social, promoviendo un desarrollo urbano desequilibrado, disperso y segregado, y deslegitimando a las instituciones involucradas. En el estudio del caso 3, en cambio, se verifica que la acción se ha llevado a cabo en beneficio de los intereses de los directamente afectados, utilizando recursos endógenos, fortaleciendo su tejido social, promoviendo un desarrollo urbano concentrado e inclusivo, e incrementando la legitimidad de las instituciones involucradas. El análisis cruzado de los resultados muestra que la pobreza, la exclusión social y la precariedad habitacional, en el contexto específico de la periferia de Dakar, no son un problema de falta de recursos, sino de falta de ética por parte de quienes gestionan y financian los procesos de transformación físico-social, y de falta de voluntad por parte de las autoridades de implicar a los ciudadanos, y en particular a los directamente afectados, en los procesos de toma de decisiones de las acciones y los programas que les afectan. Finalmente se concluye que no se trata de luchar contra la pobreza, sino de luchar contra los sistemas injustos que generan la pobreza y la exclusión. ABSTRACT The pressure on the access to land in the area of Dakar, Senegal, has generated a physical/social transformation process in the largest self-produced settlement in the urban periphery of Dakar (South Irregular Pikine), in the period 2005-2011. This research aims to analyze to what extent the actions carried out: i) satisfy the integral needs of the affected population (Demand), ii) encourage the involvement of those affected or otherwise strengthen dominant power structures (Supply), and iii) promote or inhibit economic autonomy, environmental sustainability, social equity and legitimacy of the actors involved (Environment). The research was conducted by the case study method. 196 people participated in a bottom-up participatory process of information gathering. The information collected was processed using two custom tools aimed to analyse complex systems: the program flow and the functional system. The results of case studies 1 and 2 show that the actions were carried out in the best interest of the markets and the actors who made decisions and managed resources, increasing economic dependence, impoverishing those directly affected and fragmenting their social network by promoting an unbalanced, dispersed and segregated urban development, and de-legitimizing the institutions involved in the process. On the contrary, in the case study 3 it is verified that the action has been carried out on behalf of the interests of those directly affected, using endogenous resources, strengthening the social network, promoting a focused and inclusive urban development, and increasing legitimacy of the institutions involved. The comparative analysis of the results shows that poverty, social exclusion and precarious housing in South Irregular Pikine are not a problem of lack of resources but of unethical behaviour of those who manage and finance physical and social transformation processes, as well as unwillingness on the part of the authorities to involve citizens in the decision making processes for the actions and programs that affect them. Finally we conclude that the enemy to fight against is not poverty but unfair systems that generate poverty and exclusion. RÉSUMÉ La pression sur le foncier dans la presqu'île de Dakar, au Sénégal, a généré un processus de transformation physico-sociale du plus grand établissement auto-produit de la périphérie urbaine de Dakar (Pikine Irrégulier Sud), durant la période 2005-2011. Cette recherche vise à analyser dans quelle mesure les actions menées: i) répondent ou non à l’ensemble des besoins intégrales des personnes concernés (Demande), ii) encouragent l'implication des concernées ou au contraire renforcent les structures de pouvoir dominant (Offre), et iii) favorisent ou non l'autonomie économique, la durabilité environnementale, l'équité sociale et la légitimité des acteurs concernés (Contexte). La recherche a été menée par la méthode des études de cas, par un processus de collecte d'information participative articulée du bas vers le haut dans lequel ont participé 196 personnes. Les informations recueillies ont été traitées à l'aide de deux outils d'analyse de réalités complexes: le système fonctionnel et le flux de programme. Les résultats de l'étude de cas 1 et 2 montrent que les actions ont été menées au profit des intérêts des marchés et des acteurs qui prennent les décisions et gèrent les ressources, augmentant la dépendance économique, appauvrissant ceux qui sont directement concernés et fragmentant leur tissu social, encourageant un développement urbain déséquilibré, dispersé et ségrégé, et délégitimant les institutions concernées. Dans l'étude de cas 3, cependant, il est vérifié que l'action a été menée au profit des intérêts de ceux qui sont directement concernés, en utilisant des ressources endogènes, en renforçant son tissu social, en encourageant un développement urbain concentré et inclusif, et en augmentant la légitimité des institutions concernées. L'analyse comparée des résultats montre que la pauvreté, l'exclusion sociale et le logement précaire, dans le contexte spécifique de la banlieue de Dakar, ne sont pas un problème de manque de ressources, mais de manque d'éthique de la part de ceux qui gèrent et financent les processus de transformation physico-sociale, et de manque de volonté de la part des autorités d'impliquer les citoyens, en particulier ceux qui sont directement concernés, dans le processus de prise de décision des actions et des programmes qui les impliquent. Finalement, on conclut qu'il ne s'agit pas de lutter contre la pauvreté, mais de lutter contre les systèmes injustes qui produisent la pauvreté et l'exclusion.

Evolution not revolution of farming systemswill best feed and green the world

The challenge to properly feed a world population of 9.2 billion by 2050, that must be achieved on essentially currently cropped area, requires that food production be increased by 70%. This large increase can only be achieved by combinations of greater crop yields and more intensive cropping adapted to local conditions and availability of inputs. Farming systems are dynamic and continuously adapt to changing ecological, environmental and social conditions, while achieving greater production and resource-use efficiency by application of science and technology. This article argues that the solution to feed and green the world in 2050 is to support this evolution more strongly by providing farmers with necessary information, inputs, and recognition. There is no revolutionary alternative. Proposals to transform agriculture to low-input and organic systems would, because of low productiv- ity, exacerbate the challenge if applied in small part, and ensure failure if applied more widely. The challenge is, however, great. Irrigation, necessary to increase cropping intensity in many areas cannot be extended much more widely than at present, and it is uncertain if the current rate of crop yield increase can be maintained. Society needs greater recognition of the food-supply problem and must increase funding and support for agricultural research while it attends to issues of food waste and over consumption that can make valuable reductions to food demand from agriculture

Analysis of the operator action and the single failure criteria in a SGTR sequence using best estimate assumptions with TRACE 5.0

Steam Generator Tube Rupture (SGTR) sequences in Pressurized Water Reactors are known to be one of the most demanding transients for the operating crew. SGTR are a special kind of transient as they could lead to radiological releases without core damage or containment failure, as they can constitute a direct path from the reactor coolant system to the environment. The first methodology used to perform the Deterministic Safety Analysis (DSA) of a SGTR did not credit the operator action for the first 30 min of the transient, assuming that the operating crew was able to stop the primary to secondary leakage within that period of time. However, the different real SGTR accident cases happened in the USA and over the world demonstrated that the operators usually take more than 30 min to stop the leakage in actual sequences. Some methodologies were raised to overcome that fact, considering operator actions from the beginning of the transient, as it is done in Probabilistic Safety Analysis. This paper presents the results of comparing different assumptions regarding the single failure criteria and the operator action taken from the most common methodologies included in the different Deterministic Safety Analysis. One single failure criteria that has not been analysed previously in the literature is proposed and analysed in this paper too. The comparison is done with a PWR Westinghouse three loop model in TRACE code (Almaraz NPP) with best estimate assumptions but including deterministic hypothesis such as single failure criteria or loss of offsite power. The behaviour of the reactor is quite diverse depending on the different assumptions made regarding the operator actions. On the other hand, although there are high conservatisms included in the hypothesis, as the single failure criteria, all the results are quite far from the regulatory limits. In addition, some improvements to the Emergency Operating Procedures to minimize the offsite release from the damaged SG in case of a SGTR are outlined taking into account the offsite dose sensitivity results.

Revisión de la best practice “red española de ciudades por el clima”, desde la estrategia europea medioambiental

En el siglo pasado la comunidad internacional comenzó un período de reflexión relacionado con los problemas ambientales de nuestro planeta, que ha llegado hasta hoy, situándose en el centro de discusión el problema del cambio limático. El modelo territorial impuesto ha contribuido notablemente al aumento del problema, teniendo como principal exponente el modelo de ordenación territorial y urbana. Gran parte de la transformación está en poder de los municipios, que tienen la responsabilidad de modificar el diseño y gestión de las áreas urbanas, así como del desarrollo y ejecución de políticas públicas para enfrentarnos a estos desafíos. Los programas presentados por los gobiernos nacionales o las agencias de la UE, pueden parecer ajenos o de difícil gestión por los municipios, pero en realidad sus atribuciones son adecuadas para atender a las realidades territoriales y además, de mayor comprensión por los ciudadanos.

Membrane Systems Working with the PFactor: Best Strategy to Solve Complex Problems.

A membrane system is a massive parallel system, which is inspired by the living cells when processing information. As a part of unconventional computing, membrane systems are proven to be effective in solving complex problems. A new factor is introduced. This factor can decide whether a technique is worthwhile being used or not. The use of this factor provides the best chances for selecting the strategy for the rules application phase. Referring to the “best” is in reference to the one that reduces execution time within the membrane system. A pre-analysis of the membrane system determines the P-factor, which in return advises the optimal strategy to use. In particular, this paper compares the use of two strategies based on the P-factor and provides results upon the application of them. The paper concludes that the P-factor is an effective indicator for choosing the right strategy to implement the rules application phase in membrane systems.

Best practices for school leaders: Implementation of a profesional competence model for school management in Chile

In Chile, during the last three decades there has been a strong decentralization process whose main objective has been to improve the management of schools through the transfer of responsibilities and resources of education and thus improve the outcome of learning, reducing equity gaps between schools and territories. This is how, there has been an evolution of school principals¿ professional profile from an administrative to a management approach, in which principals have become project managers of educational projects. From a competence model for school leaders, based on IPMA guidelines, the present article presents an analysis of best practices for school management, allowing to generate a link between competencies and school management, from the perspective of project management. Results showed that the different competence elements, have relative weights according to the different practice fields, and that this analysis can be considered as a strategic element in educational project planning and development.

Development of a PWR-W and an AP1000® containment building 3D model with a CFD code for Best-Estimate Thermal-Hydraulic Analysis

The simulation of design basis accidents in a containment building is usually conducted with a lumped parameter model. The codes normally used by Westinghouse Electric Company (WEC) for that license analysis are WGOTHIC or COCO, which are suitable to provide an adequate estimation of the overall peak temperature and pressure of the containment. However, for the detailed study of the thermal-hydraulic behavior in every room and compartment of the containment building, it could be more convenient to model the containment with a more detailed 3D representation of the geometry of the whole building. The main objective of this project is to obtain a standard PWR Westinghouse as well as an AP1000® containment model for a CFD code to analyze the thermal-hydraulic detailed behavior during a design basis accident. In this paper the development and testing of both containment models is presented.

Best practises for multilingual linked open data: a community effort

The W3C Best Practises for Multilingual Linked Open Data community group was born one year ago during the last MLW workshop in Rome. Nowadays, it continues leading the effort of a numerous community towards acquiring a shared view of the issues caused by multilingualism on the Web of Data and their possible solutions. Despite our initial optimism, we found the task of identifying best practises for ML-LOD a difficult one, requiring a deep understanding of the Web of Data in its multilingual dimension and in its practical problems. In this talk we will review the progresses of the group so far, mainly in the identification and analysis of topics, use cases, and design patterns, as well as the future challenges.

1950 En torno al Museo Louisiana 1970

La tesis “1950 En torno al Museo Louisiana 1970” analiza varias obras relacionadas con el espacio doméstico, que se realizaron entre 1950 y 1970 en Dinamarca, un periodo de esplendor de la Arquitectura Moderna. Tras el aislamiento y restricciones del conflicto bélico que asoló Europa, los jóvenes arquitectos daneses, estaban deseosos por experimentar nuevas ideas de procedencia internacional, favorecidos por diferentes circunstancias, encuentran el mejor campo de ensayo en el espacio doméstico. La mejor arquitectura doméstica en Dinamarca, de aquel periodo, debe entenderse como un sistema compuesto por diferentes autores, que tienen en común muchas más similitudes que diferencias, se complementan unos a otros. Para la comprensión y el entendimiento de ello se hace necesario el estudio de varias figuras y edificios, que completen este sistema cuya investigación está escasamente desarrollada. La tesis propone un viaje para conocer los nombres de algunos de sus protagonistas, que mostraron con su trabajo, que tradición y vanguardia no estarán reñidas. El objetivo es desvelar las claves de la Modernidad Danesa, reconocer, descubrir y recuperar el legado de algunos de sus protagonistas en el ámbito doméstico, cuya lección se considera de total actualidad. Una arquitectura que asume las aportaciones extranjeras con moderación y crítica, cuya íntima relación con la tradición arquitectónica y la artesanía propias, será una de sus notas especiales. Del estudio contrastado de varios proyectos y versiones, se obtienen valores comunes entre sus autores, al igual que se descubren sus afinidades o diferencias respecto a los mismos asuntos; que permitirán comprender sus actuaciones según las referencias e influencias, y definir las variables que configuran sus espacios arquitectónicos. La línea de conexión entre los edificios elegidos será su particular relación con la naturaleza y el lugar en que se integran. La fachada, lugar donde se negociará la relación entre el interior y el paisaje, será un elemento entendido de un modo diferente en cada uno de ellos, una relación que se extenderá en todas ellas, más allá de su perímetro. La investigación se ha estructurado en seis capítulos, que van precedidos de una Introducción. En el capítulo primero, se estudian y se señalan los antecedentes, las figuras y edificios más relevantes de la Tradición Danesa, para la comprensión y el esclarecimiento de algunas de las claves de su Modernidad en el campo de la Arquitectura, que se produce con una clara intención de encontrar su propia identidad y expresión. Esta Modernidad floreciente se caracteriza por la asimilación de otras culturas extranjeras desde la moderación, con un punto de vista crítico, y encuentra sus raíces ancladas a la tradición arquitectónica y la artesanía propia, que fragua en la aparición de un ideal común con enorme personalidad y que hoy se valora como una auténtica aportación de una cultura considerada entonces periférica. Se mostrará el debate y el camino seguido por las generaciones anteriores, a las obras análizadas. Las sensibilidades por lo vernáculo y lo clásico, que aparentemente son contradictorias, dominaran el debate con la misma veracidad y respetabilidad. La llamada tercera generación por Sigfried Giedion reanudará la práctica entre lo clásico y lo vernáculo, apoyados en el espíritu del trabajo artesanal y de la tradición, con el objetivo de conocer del acto arquitectónico su “la verdad” y “la esencia original”. El capítulo segundo, analiza la casa Varming, de 1953, situada en un área residencial de Gentofte, por Eva y Nils Koppel, que reinterpreta la visión de Asplund de un paisaje interior continuación del exterior, donde rompen la caja de ladrillo macizo convencional propia de los años 30. Es el ejemplo más poderoso de la unión de tradición e innovación en su obra residencial. Sus formas sobrias entre el Funcionalismo Danés y la Modernidad se singularizarán por su abstracción y volúmenes limpios que acentúan el efecto de su geometría, prismática y brutalista. El desplazamiento de los cuerpos que lo componen, unos sobre otros, generan un ritmo, que se producirá a otras escalas, ello unido a las variaciones de sus formas y a la elección de sus materiales, ladrillo y madera, le confieren a la casa un carácter orgánico. El edificio se ancla a la tierra resolviéndose en diferentes niveles tras el estudio del lugar y su topografía. El resultado es una versión construida del paisaje, en la cual el edificio da forma al lugar y ensalza la experiencia del escenario natural. La unidad de las estructuras primitivas, parece estar presente. Constituye un ejemplo de la “La idea de Promenade de Asplund”, el proyecto ofrece diferentes recorridos, permitiendo su propia vivencia de la casa, que ofrece la posibilidad vital de decidir. El capítulo tercero trata sobre el pabellón de invitados de Niels Bohr de 1957, situado un área boscosa, en Tisvilde Hegn, fue el primer edificio del arquitecto danés Vilhelm Wohlert. Arraigado a la Tradición Danesa, representa una renovación basada en la absorción de influencias extranjeras: la Arquitectura Americana y la Tradición Japonesa. La caja de madera, posada sobre un terreno horizontal, tiene el carácter sensible de un organismo vivo, siempre cambiante según las variaciones de luz del día o temperatura. Cuando se abre, crea una prolongación del espacio interior, que se extiende a la naturaleza circundante, y se expande hacia el espacio exterior, permitiendo su movilización. Se establece una arquitectura de flujos. Hay un interés por la materia, su textura y el efecto emocional que emana. Las proporciones y dimensiones del edificio están reguladas por un módulo, que se ajusta a la medida del hombre, destacando la gran unidad del edificio. La llave se su efecto estético está en su armonía y equilibrio, que transmiten serenidad y belleza. El encuentro con la naturaleza es la lección más básica del proyecto, donde un mundo de relaciones es amable al ser humano. El capítulo cuarto, analiza el proyecto del Museo Louisiana de 1958, en Humlebæk, primer proyecto de la pareja de arquitectos daneses Jørgen Bo y Vilhelm Wohlert. La experiencia en California de Wohlert donde será visitado por Bo, será trascendental para el desarrollo de Louisiana, donde la identidad Danesa se fusiona con la asimilación de otras culturas, la arquitectura de Frank Lloyd Wright, la del área de la Bahía y la Tradición Japonesa principalmente. La idea del proyecto es la de una obra de arte integral: arquitectura, arte y paisaje, coexistirían en un mismo lugar. Diferentes recursos realzarán su carácter residencial, como el uso de los materiales propios de un entorno doméstico, la realización a la escala del hombre, el modo de usar la iluminación. Cubiertas planas que muestran su artificialidad, parecen flotar sobre galerías acristaladas, acentuarán la fuerza del plano horizontal y establecerán un recorrido en zig-zag de marcado ritmo acompasado. Ritmo que tiene que ver con la encarnación del pulso de la naturaleza, que se acompaña de juegos de luz, y de otras vibraciones materiales a diferentes escalas, imagen, que encuentra una analogía semejante en la cultura japonesa. Todo se coordina con la trama estructural, que conlleva a una construcción y proporción disciplinada. Louisiana atiende al principio de crecimiento de la naturaleza, con la que su conexión es profunda. Hay un dinamismo expresado por el despliegue del edificio, que evoca a algunos proyectos de la Tradición Japonesa. Los blancos muros tienen su propia identidad como formas en sí mismas, avanzan prolongándose fuera de la línea del vidrio, se mueven libremente siguiendo el orden estructural, acompañando al espacio que fluye, en contacto directo con la naturaleza que está en un continuo estado de flujos. Se da todo un mundo de relaciones, donde existe un dialogo entre el paisaje, arte y arquitectura. El capítulo quinto, se dedica a analizar la segunda casa del arquitecto danés Halldor Gunnløgsson, de 1959. Evoca a la Arquitectura Japonesa y Americana, pero es principalmente resultado de una fuerte voluntad y disciplina artística personal. La cubierta, plana, suspendida sobre una gran plataforma pavimentada, que continúa la sección del terreno construyendo de lugar, tiene una gran presencia y arroja una profunda sombra bajo ella. En el interior un espacio único, que se puede dividir eventualmente, discurre en torno a un cuerpo central. El espacio libre fluye, extendiéndose a través de la transparencia de sus ventanales a dos espacios contrapuestos: un patio ajardinado íntimo, que inspira calma y sosiego; y la naturaleza salvaje del mar que proyecta el color del cielo, ambos en constante estado de cambio. El proyecto se elabora de un modo rigurosamente formal, existiendo al mismo tiempo un perfecto equilibrio entre la abstracción de su estructura y su programa. La estructura de madera cuyo orden se extiende más allá de los límites de su perímetro, está formada por pórticos completos como elementos libres, queda expuesta, guardando una estrecha relación con el concepto de modernidad de Mies, equivalente a la arquitectura clásica. La preocupación por el efecto estético es máxima, nada es improvisado. Pero además la combinación de materiales y el juego de las texturas hay una cualidad táctil, cierto erotismo, que flota alrededor de ella. La precisión constructiva y su refinamiento se acercan a Mies. La experiencia del espacio arquitectónico es una vivencia global. La influencia de la arquitectura japonesa, es más conceptual que formal, revelada en un respeto por la naturaleza, la búsqueda del refinamiento a través de la moderación, la eliminación de los objetos innecesarios que distraen de la experiencia del lugar y la preocupación por la luz y la sombra, donde se establece cierto paralelismo con el oscuro mundo del invierno nórdico. Hay un entendimiento de que el espacio, en lugar de ser un objeto inmaterial definido por superficies materiales se entiende como interacciones dinámicas. El capítulo sexto. Propone un viaje para conocer algunas de las viviendas unifamiliares más interesantes que se construyeron en el periodo, que forman parte del sistema investigado. Del estudio comparado y orientado en varios temas, se obtienen diversa conclusiones propias del sistema estudiado. La maestría de la sustancia y la forma será una característica distintiva en Dinamarca, se demuestra que hay un acercamiento a la cultura de Oriente, conceptual y formal, y unos intereses comunes con cierta arquitectura Americana. Su lección nos sensibiliza hacia un sentido fortalecido de proporción, escala, materialidad, textura y peso, densidad del espacio, se valora lo táctil y lo visual, hay una sensibilidad hacia la naturaleza, hacia lo humano, hacia el paisaje, la integridad de la obra. ABSTRACT The thesis “1950 around the Louisiana Museum 1970” analyses several works related to domestic space, which were carried out between 1950 and 1970 in Denmark, a golden age of modern architecture. After the isolation and limitations brought about by the war that blighted Europe, young Danish architects were keen to experiment with ideas of an international origin, encouraged by different circumstances. They find the best field of rehearsal to be the domestic space. The best architecture of that period in Denmark should be understood as a system composed of different authors, who have in common with each other many more similarities than differences, thus complimenting each other. In the interests of understanding, the study of a range of figures and buildings is necessary so that this system, the research of which is still in its infancy, can be completed. The thesis proposes a journey of discovery through the names of some of those protagonists who were showcased through their work so that tradition and avant- garde could go hand in hand. The objective is to unveil the keys to Danish Modernity; to recognise, discover and revive the legacy of some of its protagonists in the domestic field whose lessons are seen as entirely of the present. For an architect, the taking on of modern contributions with both moderation and caution, with its intimate relationship with architectural tradition and its own craft, will be one of his hallmarks. With the study set against several projects and versions, one can derive common values among their authors. In the same way their affinities and differences in respect of the same issue emerge. This will allow an understanding of their measures in line with references and influences and enable the defining of the variables of their architectural spaces. The common line between the buildings selected will be their particular relationship with nature and the space with which they integrate. The façade, the place where the relationship between the interior and the landscape would be negotiated, wouldl be the discriminating element in a distinct way for each one of them. It is through each of these facades that this relationship would extend, and far beyond their physical perimeter. The investigation has been structured into six chapters, preceded by an introduction. The first chapter outlines and analyses the backgrounds, figures and buildings most relevant to the Danish Tradition. This is to facilitate the understanding and elucidation of some of the keys to its modernity in the field of architecture, which came about with the clear intention to discover its own identity and expression. This thriving modernity is characterized by its moderate assimilation with foreign cultures with a critical eye, and finds its roots anchored in architectural tradition and its own handcraft. It is forged in the emergence of a common ideal of enormous personality which today has come to be valued as an authentic contribution to the sphere from a culture that was formerly seen as on the peripheries. What will be demonstrated is the path taken by previous generations to these works and the debate that surrounds them. The sensibilities for both the vernacular and the classic, which at first glance may seem contradictory, will dominate the debate with the same veracity and respectability. The so-called third generation of Sigfried Giedion will revive the process between the classic and the vernacular, supported in spirit by the handcraft work and by tradition, with the objective of discovering the “truth” and the “original essence” of the architectural act. The second chapter analyzes the Varming house, built by Eva and Nils Koppel 1953, which is situated in a residential area of Gentofte. This reinterprets Asplund’s vision of an interior landscape extending to the exterior, where we see a break with the conventional sturdy brick shell of the 1930s. It is the most powerful example of the union of tradition and innovation in his their residential work. Their sober forms caught between Danish Functionalism and modernity are characterized by their abstraction and clean shapes which accentuate their prismatic and brutal geometry, The displacement of the parts of which they are composed, one over the other, generate a rhythm. This is produced to varying scales and is closely linked to its forms and the selection of materials – brick and wood – that confer an organic character to the house. The building is anchored to the earth, finding solution at different levels through the study of place and topography. The result is an adaption constructed out of the landscape, in which the building gives form to the place and celebrates the experience of the natural setting. The unity of primitive structures appears to be present. It constitutes an example of “Asplund’s Promenade Idea”. Different routes of exploration within are available to the visitor, allowing for one’s own personal experience of the house, allowing in turn for the vital chance to decide. The third chapter deals with Niels Bohr’s guest pavilion. Built in 1957, it is situated in a wooded area of Tisvilde Hegn and was the architect Vilhelm Wohlert’s first building. Rooted in the Danish Tradition, it represents a renewal based on the absorption of foreign influences: American architecture and the Japanese tradition. The wooden box, perched atop a horizontal terrain, possesses the sensitive character of the living organism, ever-changing in accordance with the variations in daylight and temperature. When opened up, it creates an elongation of the interior space which extends into the surrounding nature and it expands towards the exterior space, allowing for its mobilisation. It establishes an architecture of flux. There is interest in the material, its texture and the emotional effect it inspires. The building’s proportions and dimensions are regulated by a module, which is adjusted by hand, bringing out the great unity of the building. The key to its aesthetic effect is its harmony and equilibrium, which convey serenity and beauty. The meeting with nature is the most fundamental lesson of the project, where a world of relationships softens the personality of the human being. The fourth chapter analyzes the Louisiana Museum project of 1958 in 1958. It was the first project of the Danish architects Jørgen Bo and Vilhelm Wohlert. Wohlert’s experience in California where he was visited by Bo would be essential to the development of Louisiana, where the Danish identity is fused in assimilation with other cultures, the architecture of Frank Lloyd Wright, that of the Bahía area and principally the Japanese tradition. The idea of the project was for an integrated work of art: architecture, art and landscape, which would coexist in the same space. A range of different resources would realize the residential character, such as the use of materials taken from a domestic environment, the attainment of human scale and the manner in which light was used. Flat roof plans that show their artificiality and appear to float over glassed galleries. They accentuate the strength of the horizontal plan and establish a zigzag route of marked and measured rhythm. It is a rhythm that has to do with the incarnation of nature’s pulse, which is accompanied with plays of light, as well as material vibrations of different scales, imagery which uncovers a parallel analogy with Japanese culture. Everything is coordinated along a structural frame, which involves a disciplined construction and proportion. Louisiana cherishes nature’s principle of growth, to which its connection is profound. Here is a dynamism expressed through the disposition of the building, which evokes in some projects the Japanese tradition. The white walls possess their own identity as forms in their own right. They advance, extending beyond the line of glass, moving freely along the structural line, accompanying a space that flows and in direct contact with nature that is itself in a constant state of flux. It creates a world of relationships, where dialogue exists between the landscape, art and architecture. The fifth chapter is dedicated to analyzing the Danish architect Halldor Gunnløgsson’s second house, built in 1959. It evokes both Japanese and American architecture but is principally the result of a strong will and personal artistic discipline. The flat roof suspended above a large paved platform – itself continuing the constructed terrain of the place – has great presence and casts a heavy shadow beneath. In the interior, a single space, which can at length be divided and which flows around a central space. The space flows freely, extending through the transparency of its windows which give out onto two contrasting locations: an intimate garden patio, inspiring calm and tranquillity, and the wild nature of the sea which projects the colour of sky, both in a constant state of change. The project is realized in a rigorously formal manner. A perfect balance exists between the abstraction of his structure and his project. The wooden structure, whose order extends beyond the limits of its perimeter, is formed of complete porticos of free elements. It remains exposed, maintaining a close relationship with Mies’ concept of modernity, analogous to classical architecture. The preoccupation with the aesthetic effect is paramount and nothing is improvised. But in addition to this - the combination of materials and the play of textures - there is a tactile quality, a certain eroticism, which lingers all about. The constructive precision and its refinement are close to Mies. The experience of the architectural space is universal. The influence of Japanese architecture, more conceptual than formal, is revealed in a respect for nature. It can be seen in the search for refinement through moderation, the elimination of the superfluous object that distract from the experience of place and the preoccupation with light and shade, where a certain parallel with the dark world of the Nordic winter is established. There is an understanding that space, rather than being an immaterial object defined by material surfaces, extends instead as dynamic interactions. The sixth chapter. This proposes a journey to discover some of the unfamiliar residences of most interest which were constructed in the period, and which form part of the system being investigated. Through the study of comparison and one which is geared towards various themes, diverse conclusions are drawn regarding the system being researched. The expertise in substance and form will be a distinctive characteristic in Denmark, demonstrating an approach to the culture of the Orient, both conceptual and formal, and some common interests in certain American architecture. Its teachings sensitize us to a strengthened sense of proportion, scale, materiality, texture and weight and density of space. It values both the tactile and the visual. There is a sensitivity to nature, to the human, to the landscape and to the integrity of the work.

Re-Ocupación y/o Re-Construcción de estructuras urbanas en desuso y su conexión con el espacio público y el paisaje

Los nuevos comportamientos urbanos nos permiten observar cada vez con más frecuencia en nuestras calles y plazas realidades que siempre habíamos considerado domésticas. Al contrario también pasa, todos los días vivimos en nuestras casas situaciones que implican relacionarnos con personas que no son de nuestro núcleo familiar. El diseño doméstico de nuestras ciudades y el urbanismo del diseño de interiores parecen herramientas oportunas en el mundo que nos ha tocado vivir. Esto nos lleva a pensar que los espacios públicos y privados son términos simplificados, definidos en base a conceptos de propiedad para organizar la ciudad. En cambio, sus usos y vivencias, su gestión y sus comportamientos se han complejizado, distorsionando la terminología convencional hasta hacerla obsoleta. En este contexto, considerado también el marco socioeconómico actual, surgen las “acciones de abajo a arriba” como nuevo paradigma o modelo de renovación urbana, que entienden la involucración del ciudadano como parte activa en el proceso de construcción de la urbe desde la misma gestación del proyecto, frente a las acciones habituales que consideran al usuario como mero receptor de las propuestas. Un ciudadano que parece estar cada vez más radicalizado y una administración que parece asustarse ante el desconcierto que el acercamiento al ciudadano puede acarrear, han ocasionado por un lado, espacios “gueto” de carácter casi anárquico y, por el otro lado, lugares tan institucionalizados que derivan en espacios asociados a la administración y ajenos al ciudadano. Por ello, se considera imprescindible la colaboración entre ambos poderes. De acuerdo con el discurso que precede, dentro de un marco comparativo, se estudian 5 supuestos seleccionados de las ciudades Madrid y Zaragoza. Madrid porque es referencia nacional e internacional en el desarrollo urbano a través de procesos ‘abajo arriba’. Zaragoza porque es una ciudad ‘media’ que históricamente no se ha definido por estrategias urbanas claras, ya sean de carácter social o institucional. Sin embargo, en el momento actual se pueden identificar planteamientos relacionados con la recuperación de construcciones y espacios vacantes que pueden ser determinantes a la hora de alcanzar equilibrios con los intensos procesos institucionales acaecidos en las dos últimas décadas. De los procesos urbanos registrados en cada lugar, desarrollados en construcciones y espacios vacantes, he seleccionado: Construcciones Vacantes Madrid |Tabacalera de Lavapiés Zaragoza | Antiguo I.E.S. Luis Buñuel y antiguo Convento de Mínimos Espacios Vacantes Madrid | Campo de Cebada [solar] Zaragoza | Patio ‘antiguo I.E.S. Luis Buñuel [espacio libre] y plaza Eduardo Ibarra [espacio libre] El proyecto de investigación ha partido de las hipótesis de partida que siguen: UNA… Las ‘acciones de abajo arriba’ o renovación desde abajo no tienen cabida como elementos urbanos aislados sino conectados entre sí, posibilitando la producción de sinergias y la construcción de la ciudad; pudiendo ser consideradas acciones de desarrollo y enlace urbano, pues su objetivo es convertirse en motores del espacio público. Cuestión que es aplicable al resto de los procesos o acciones urbanas [‘horizontales’ o ‘institucionales’] DOS… La capacidad de adaptación manifestada por las ‘acciones de abajo arriba’ implica un marco ideológico de referencia asociado a la importancia de la construcción con mínimos recursos [Re-ocupación y/o Re- Construcción de estructuras urbanas en desuso] en los procesos urbanos descritos, como vía para comprender los concepto sostenibilidad y calidad figurativa de lo construido. Cuestión que es aplicable a la recuperación de aquellos aspectos de la arquitectura que la convierten en necesaria para la sociedad. Y tiene como objetivo: Identificar modelos de sostenibilidad urbana como una estrategia que va de lo individual a lo colectivo y que se transmite fundamentalmente con la acción, mezclando la innovación y la tecnología en múltiples ámbitos, utilizando los recursos naturales e intelectuales de una manera eficiente y entendiendo la inteligencia humana y sobre todo la inteligencia colectiva, como principio y justificación. Se han analizado los siguientes aspectos: sociales [participación ciudadana e implicación de la administración pública], urbanos [conexiones con otros colectivos o espacios urbanos / transformaciones urbanas a través de los procesos de gestión utilizados], constructivos [materiales utilizados en la re-construcción de construcciones y espacios vacantes / sistemas constructivos utilizados] y los relacionados con la sostenibilidad [sostenibilidad económica / sostenibilidad de mantenimiento / sostenibilidad funcional / inteligencia colectiva] El estudio de los aspectos considerados se ha desarrollado con las herramientas metodológicas siguientes: Entrevistas abiertas a expertos: se han obtenido respuestas de 25 personas expertas [5 por cada espacio o construcción vacante] relacionadas con las acciones urbanas sostenibles, la cultura y las relaciones sociales, y que también conocen los lugares y su entorno desde los puntos de vista urbano y construido. Son ‘tipos ideales’ asociados a uno de los cinco poderes que se manifiestan en la ciudad: el poder educativo [la universidad], el poder creativo [la cultura], el poder administrativo [la política], el poder empresarial [la empresa privada] y los usuarios [un usuario activo y representativo de cada lugar elegido que haya intervenido en la gestación del proceso]. Han sido personas que conocían el tejido social y urbano de la ciudad de Zaragoza y Madrid, ya que la herramienta ‘entrevista abierta a expertos’, recoge datos y opiniones planteadas en las construcciones y espacios vacantes ubicados en Zaragoza y Madrid. Entrevistas cerradas a usuarios: como la población de usuarios que se somete a la investigación es infinita o muy grande, resulta imposible o inconveniente realizar la obtención de los datos sobre todos aquellos elementos que la forman. Por lo tanto, he decidido estudiar sólo una parte de la población que denomino ‘tipos ideales’, obteniendo respuestas de 150 usuarios [30 personas por cada espacio o construcción vacante]. La selección de grupos de personas entrevistadas, debe permitir que los resultados sean representativos de la población total de usuarios. Además, la elección de ‘tipos ideales’ se ha identificado con los vecinos de los núcleos urbanos [o barrios] en los que se ubican las construcciones o espacios vacantes analizados. Observación estructurada: recoger información a través de la observación me ha permitido conocer las actuaciones y comportamientos de los ciudadanos en el medio urbano. Esto ha facilitado el estudio del medio a nivel práctico, valorando el uso que la sociedad da a las construcciones y a los espacios vacantes analizados. Es importante posicionar la estrategia en relación con el tema de investigación propuesto. Una estrategia que dibuje un panorama plural, desarrollado a través de herramientas sociales y constructivas que permitan que la arquitectura hable de cosas parecidas a lo que interesa a la ciudadanía. Para ello, propuse un catálogo de herramientas arquitectónicas que han permitido evaluar todas las propuestas. Un contexto de estrategias comunes que han descrito con los mismos códigos las distintas actuaciones analizadas. Estas herramientas tocan diferentes campos de interés. Desde las partes más tectónicas y constructivas, hasta las más ligadas con el desarrollo urbanístico y social. Acciones de participación colectiva: Experiencias o laboratorios urbanos participados por los alumnos del grado de arquitectura de la UNIZAR y los agentes sociales. Las acciones son una herramienta propositiva. Investigar y analizar proponiendo ha permitido que el análisis del contexto pueda llegar a capas de mucha más profundidad. No se ha trabajado estableciendo jerarquías de profesores y alumnos, sino que se ha intentado posibilitar la conexión de distintos agentes que trabajan coordinadamente durante el tiempo que han durado las acciones. Por un lado esto ha permite que cada integrante haya aportado al grupo lo que mejor sabe hacer y de la misma manera, que cada uno pueda aprender aquello de lo que tenga más ganas… y reflexionar sobre determinados aspectos objeto del análisis. Una vez interpretados los resultados, obtenidos a través de las herramientas metodológicas referenciadas, se ha concluido lo que sigue: Respecto de la Hipótesis de partida UNO LAS ACCIONES ‘ABAJO ARRIBA’ han revelado que no se puede entender ningún proceso de gestión urbana fuera de la participación ciudadana. El ‘ESPACIO LIBRE’ de una ciudad necesita lugares de autogestión, espacios de cogestión, movimientos de ‘arriba abajo’ y también modelos que todavía no sabemos ni que existen. LAS ACCIONES INSTITUCIONALES ‘ARRIBA ABAJO’ han demostrado que no han presentado permeabilidad ni relación con las circulaciones de entorno. Tampoco han tenido en cuenta a otras muchas personas, ‘usuarios productores’, a las que les interesan los procesos de búsqueda y las fórmulas de conexión más interactivas. Respecto de la hipótesis de partida DOS LAS ACCIONES ‘ABAJO ARRIBA’ han revelado que el ‘derecho a la ciudad’, paradigma defendido por Lefebvre desde el cual se piensa el urbanismo ciudadano, en estos supuestos podría entenderse como el ‘derecho a la infraestructura’. El ESPACIO LIBRE es infraestructura y se quiere para infraestructurar los derechos de cada uno. Y aunque también es verdad que estas acciones son simples destellos, han hecho visible otro paradigma de gestión y propuesta urbana que puede ser predominante en un futuro próximo. LAS ACCIONES INSTITUCIONALES ‘ARRIBA ABAJO’ han revelado que las intervenciones estuvieron enfocadas únicamente a la resolución de los procesos constructivos y a la incorporación del programa como un dato ‘problema’ que era necesario resolver para evitar la afección al diseño. ABSTRACT The new urban ways of behaviour let us watch more and more frequently in our streets and squares, realities that we had always considered as domestic. This also happens the other way round. Every day we have to go through situations at home which imply relationships with people who don’t belong to our family circle. The domestic design of our cities and the urban planning of indoor design seem to be adequate tools in the world we have to live in. This leads us to think that public and private spaces are simplified terms, defined according to concepts of property in order to organise the city. On the other hand, its uses and the experiences of people, its management and ways of behaviour is now more complex, changing the conventional terminology that has become outdated. In this context, ‘bottom-up’ actions arise as a new paradigm or model of urban renewal. These actions consider the active role of social participation in the process of building up the city from the very beginning, in comparison with the former way of acting that considered the user as mere receptor of the proposals. A citizen who seems to become more and more radical, and an administration that seems to be afraid of the unknown, have created both almost anarchic ghetto spaces and, on the other hand, spaces which have been so institutionalised that derive into areas associated to the administration but alienated from the citizen. For this reason, cowork of both forces is considered as crucial. In accordance with the above mentioned ideas and within a comparative framework, five situations chosen from the cities of Madrid and Zaragoza are studied. Madrid because is a national and international reference in urban development that uses “bottom-up” processes. Zaragoza because is a “medium-size” city that, historically, has not been defined by clear social or institutional urban strategies. Nevertheless, at the present time we can identify approaches on the recovery of constructions and empty areas that may be determining for reaching a balance with the intense institutional processes that have taken place in the two last decades. From the urban processes registered in every place and developed in vacant areas and constructions, I have chosen: Vacant constructions Madrid | Lavapiés Tobacco Factory Zaragoza | Old Secondary School Luis Buñuel and old Convent of the Minimos Vacant areas Madrid | Campo de Cebada [non-built site]. Zaragoza | Old courtyard of the secondary school and Eduardo Ibarra square [free space] The research project has been issued from the following starting hypotheses: ONE… “Bottom-up actions” or renewal from below have no place as isolated urban elements but as connected parts that can produce synergies and the construction of the city, and that can also be considered as actions producing urban development and links. This can also be applied to the rest of urban processes or actions [‘horizontal’ or ‘institutional’]. TWO… The capacity of adaptation shown by “bottom-up actions” implies an ideological framework of reference which is related to the importance of construction with minimal resources (re-occupation and/or reconstruction of urban structures in disuse) in the above mentioned urban processes, as a way for understanding the concepts of sustainability and the representational quality of what has been constructed. This can also be applied to the recovery of those architectural aspects that make architecture necessary for society. And its objective is: Identify models of urban sustainability as a strategy going from the individual to the collective, which are mainly transferred by action and that mix innovation and technology in many fields. Models that use natural and intellectual resources in an efficient way, and understand human intelligence and, above all, collective intelligence, as principle and justification. The following aspects have been analysed: social [civic participation and involvement of the public Administration], urban [connections with other collectives or urban spaces / urban transformation by the processes of administration used], constructive [materials used for the re-construction of empty spaces / construction systems used] and those focusing on sustainability [economic sustainability /maintenance sustainability /functional sustainability / collective intelligence]. For researching into the above mentioned aspects, the following methodological tools have been developed: Open interviews with experts: answers from 25 experts have been obtained [five for every vacant space or empty construction] on sustainable urban actions, culture and social relations, who also know the places and their environment from an urban and constructive point of view. These are “ideal types” linked to one of the five powers acting in the city: the educational power [University], the creative power [culture], the administration power [politics], the corporate power [private companies] and the users [an active and representative user for every place selected during the establishment of the process]. They were people who knew the social and urban fabric of Zaragoza and Madrid, since the “open interview for experts” tool collects data and points of view set out in vacant constructions and spaces of Zaragoza and Madrid. Close interviews with users: as the number of users targeted for the research is very big or infinite, it is impossible or inconvenient to get data from all its constituent parts. Therefore, I have decided to research into the part of the population that I call “ideal types”, obtaining answers from 150 users [30 people for every empty space or construction]. The selection of the groups of people interviewed must produce results which are representative of the total population of users. Furthermore, the election of “ideal types” has been identified with the inhabitants of urban areas [or city districts] in which the vacant spaces or constructions analysed are located. A structured observation: I have known the actions and ways of behaving of the citizens in the urban environment by means of collecting information after observation. Therefore, the practical research into the target environment has been easier by valuing the use that society gives to the empty constructions and spaces analysed. It is important to position the strategy with respect to the research subject proposed. It involves a strategy able to get an overview of a plural landscape, developed by social and constructive tools, allowing architecture to talk about topics which are interesting for city dwellers. Therefore, I proposed a set of architectural tools to evaluate all the proposals. A context of common strategies describing the different actions analysed by using the same codes. These tools focus on different fields of interests, from the most tectonic and constructive parts, to the most related to urban and social development. Actions on collective participation: experiences or urban laboratories shared by the students of architecture of the University of Zaragoza and social agents. The actions are a proactive tool. Researching and analysing by means of proposing, has allowed me to analyse the context and much deeper layers. This work has not been done by establishing ranks of professors and student, but trying to get an interaction between the different agents who work in close coordination during the implementation of the actions. This has allowed every agent to contribute the group what they do the best, and also every individual has had the possibility to learn what s/he prefers…, thinking about the different aspects targeted by the analysis. Once the different methodological tools have been interpreted, this is the conclusion: With regard to the initial hypothesis ONE “BOTTOM-UP” ACTIONS have proven that no process of urban management can be understood outside civic participation. The “FREE SPACE” of a city needs self-managed places, co-managed spaces, “up-bottom” movements, and also models whose existence is still ignored. “UP-BOTTOM” INSTITUTIONAL ACTIONS have proven that they have not presented neither permeability nor relation with local ideas. They have also disregarded many other people, the “usersproducers”, who are interested in the most interactive means of searching and connecting processes. With regard to the initial hypothesis TWO Under these premises, “BOTTOM-UP” ACTIONS have shown that the “right to the city”, a paradigm defended by Lefebvre and from which citizen-focused urbanism is conceived, could be considered as a “right to the infrastructures”. A FREE SPACE is an infrastructure and must be used to “infrastructure” the rights of every citizen. And, even though it is true that these actions are mere flashes, they have made visible another paradigm of management and urban proposal that can be prevailing in a near future. “UP-BOTTOM” INSTITUTIONAL ACTIONS have revealed that the interventions have only focused on resolving construction processes and the incorporation of the program as a “problem” data that was necessary to resolve in order to avoid its influence on the design.
