Arqueología del futuro

A través de la historia aparecen muchas y variadas manifestaciones de cambio, necesarias para afrontar el futuro2 de la humanidad; también de la arquitectura. Estas manifestaciones, alternativas, teorías y proyectos, a menudo denostados por la crítica o dejados de lado por las teorías históricas de carácter generalista, destacan por su capacidad de convertirse en herramientas críticas frente al orden establecido, promoviendo así nuevos imaginarios colectivos. En el contexto temporal que transcurre desde finales de la década de los años cincuenta hasta mediados de los setenta, esa “búsqueda del futuro” no sólo se encuentra totalmente aceptada y popularizada, sino que llega a convertirse en un acto necesario, legitimado por la incorporación de la futurología como ciencia de estudio fundamental. Este contexto resulta el marco idóneo para la aparición de una serie de predicciones arquitectónicas encaminadas a dibujar nuevos caminos posibles para el futuro de la arquitectura, o lo que es lo mismo, para una arquitectura del futuro: “Où vivrons-nous demain ?” (1963) y “Les cités de l'avenir” (1966) del historiador francés Michel Ragon, el número “AD 2000+” (1967) de la revista Architectural Design y “The Future of the Future” (1969) del artista inglés John McHale, “Architecture: action and plan” (1967) y “Experimental Architecture” (1970) de Peter Cook, “Megastructure. Urban futures of the recent past” del crítico inglés Reyner Banham, “Architecture 2000” (1971) del norteamericano Charles Jencks, “Stadstrukturen für morgen” (1971) del suizo Justus Dahinden, “Arthropods: new design futures” (1972) del editor norteamericano Jim Burns y la sección “Cosmorama” (1965-1973) de la revista inglesa Architectural Design, pueden considerarse como las más destacadas. A pesar de lo heterogéneo de sus autores y enfoques, todas ellas gravitan en torno a cuatro alternativas para una redefinición del futuro de la arquitectura: - La incorporación de la arquitectura al heterogéneo espectro formal derivado de la explosión de las artes visuales y la exuberancia y proliferación de los objetos de consumo a través de un CAMBIO DE ESCALA. - La generación de nuevas relaciones que experimenten en torno a los límites entre natural y artificial, o PERVERSIONES NATURALES. - La apertura de un nuevo camino, HACIA UNA ARQUITECTURA VIRTUAL, que experimente con una construcción de ambientes auspiciada por los avances tecnológicos derivados del control perceptivo. - LA MOVILIDAD COMO OPCIÓN DE FUTURO, una respuesta a la aparición de una nueva sociedad en continuo cambio, abogando por estructuras más flexibles en todos los campos del ámbito arquitectónico, de lo urbano a lo doméstico. ABSTRACT of humanity, and of architecture too. Those signs, alternatives, theories and projects, that were often neglected by the critics or left aside by historical theories of general-interest, have an outstanding capacity to become critical tools with regards to the established order, and to promote new collective imagery. Within the timeframe that lasts between late fifties and midseventies, that "quest for the future" is not only accepted and made popular, but it even becomes an act of necessity that is legitimized by the incorporation of futurology as a key scientific field of study. This timeframe provides the most suitable context for the appearance of a series of architectonical predictions that are aimed to define new potential paths for the future architecture to follow, in other words, an architecture of the future: "Où vivrons-nous demain?" (1963) y "Les cités de l'avenir" (1966) from French historian Michel Ragon, issue number "AD 2000+" (1967) of Architectural Design magazine and "The Future of the Future" (1969) from English artist John McHale, "Architecture: action and plan" (1967) and "Experimental Architecture" (1970) from Peter Cook, "Megastructure. Urban futures of the recent past" from English critic Reyner Banham, "Architecture 2000" (1971) from North-American Charles Jencks, "Stadstrukturen für morgen" (1971) from Swiss Justus Dahinden, "Arthropods: new design futures" (1972) from North-American editor Jim Burns and the section "Cosmorama" (1965-73) from English magazine Architectural Design, can be considered as the most prominent architectonical predictions of that time. Despite the heterogeneity of authors and approaches, all of them are built around four alternatives that are aimed to re-define the future of architecture: - The incorporation of architecture to the heterogeneous formal spectrum of visual arts and the exuberance and the proliferation of objects of massive consumerism through an operation of CHANGE IN SCALE. - The production of new relationships aimed to experiment around the limits between natural and artificial, in other words, NATURAL PERVERSIONS. - A new road TOWARDS VIRTUAL ARCHITECTURE, to enable experiences with ambiance construction that are favored by technological advances derived from the control of perception. - MOVILITY AS AN OPTION FOR THE FUTURE, a response to the appearance of a new ever changing society, a bet on more flexible structures in all areas of architecture, from urban to domestic scale.

La silla de la discordia : la pequeña escala como campo de experimentación en la modernidad : Breuer, Mies y Stam

El siglo XIX fue un siglo dedicado a los grandes edificios públicos. Los teatros, las academias, los museos. Sin embargo la arquitectura durante el siglo XX se dedicará al estudio de la casa. Todos los usos y tipologías se verán fuertemente revisados pero el núcleo de todos los esfuerzos y verdadero inicio de la arquitectura moderna será la vivienda. A partir de ella todos los preceptos modernos se irán aplicando a los distintos programas. Nikolaus Pevsner señala a William Morris como el primer arquitecto moderno porque precisamente entendió que un arte verdaderamente social, en consonancia con su tiempo y la sociedad a la que sirve, ha de ocuparse de aquello que preocupe a la gente. Con la nueva situación de la vivienda en el centro de las motivaciones disciplinares el mueble adopta un nuevo protagonismo. En un momento avanzado de su carrera Marcel Breuer observa entre curioso e irónico cómo el mueble moderno había sido promocionado paradójicamente no por los diseñadores de muebles sino por los arquitectos1. La respuesta la da Le Corbusier en una de sus conferencias de 1931 recogida en Precisiones 2 cuando señala la reformulación del mobiliario como el "nudo gordiano" de cuya resolución pendía la renovación de la planta moderna. El Movimiento Moderno se había visto obligado a atacar este tema para poder avanzar en sus propuestas domésticas. El Movimiento Moderno se propuso solucionar los problemas de la vivienda y de una Europa en reconstrucción pero se exigía además ser capaz de aportar una visión propositiva de la vida moderna. No se trataba únicamente de resolver los problemas ya existentes sino que además había la necesidad autoimpuesta de anticipar la domesticidad del futuro. Para ello sus viviendas al completo, mueble e inmueble, debían de presentarse bajo esa nueva imagen. El manifiesto fundacional de la Deustcher Werkbund extendía el radio de acción del nuevo arquitecto desde la construcción de las ciudades a los cojines del sofá. Este mobiliario tenía la compleja misión de condensar sintéticamente todos esos ideales que la modernidad había traído consigo: abstracción, higiene, fascinación maquínica, confianza positivista en la ciencia o la expresión material optimizada. Objetos de la vida moderna, en palabras de Le Corbusier, susceptibles de suscitar un estado de vida moderno. Pocas sillas en la historia del diseño habrán acarreado tanta polémica y tanta disputa por su autoría como la sillas voladas de tubo de acero en sus diferentes versiones. Para entenderlo situémonos en el año 1927 a las puertas de la exposición "Die Wohnung" ("La vivienda") organizada por los maestros de la Bauhaus y dirigida por Mies van der Rohe en la ladera Weissenhof de Stuttgart. Muchos nombres célebres de la arquitectura mostraron en esa ocasión su personal propuesta para la vivienda moderna y los objetos que la habitan. Entre ellos los muebles con tubo de acero fueron una presencia constante en la exposición pero hubo una pieza que destacó sobre todas las demás por su novedad y audacia. La pieza en cuestión era el modelo de silla volada, esto es, sin apoyos posteriores y cuya rigidez estaba conferida al esfuerzo solidario de la estructura continua de tubo de acero y que terminaría por convertirse en el cruce de caminos de tres figuras de la disciplina arquitectónica: Marcel Breuer, Mies van der Rohe y Mart Stam. Cada uno de ellos desarrolló su propio modelo de silla volada en sus versiones MR por parte de Mies, L&C Arnold de Stam y el posterior modelo BR 33 de Marcel Breuer. Los tres, en algún momento de su vida reclamaron de uno u otro modo su autoría como objetos que les pertenecían intelectualmente. Estas sillas se convirtieron en la expresión máxima de uno de los ansiados anhelos de la modernidad, la propia materialidad del acero, en su versión optimizada, era la que había derivado en una forma completamente nueva de un objeto cotidiano y cuyo tipo estaba ya totalmente asumido. Los nuevos materiales y las nuevas formas de hacer habían irrumpido hasta en los utensilios domésticos, y habían sido capaces de reformularlos. El punto de partida para esta investigación es precisamente esa coincidencia de tres figuras de la arquitectura moderna, los tres de formación artesanal, en un mismo modelo de silla y en una misma fecha. Tres arquitectos que se habían encargado de asegurar que el movimiento moderno no reconocía problemas formales sino solamente de construcción, iban a coincidir en el mismo tiempo y lugar, precisamente en una misma forma, como si tal coincidencia hubiera sido producto de una voluntad de época. Sin embargo el interés de este estudio no radica en una indagación sobre la autoría sino sobre cómo un mismo objeto resulta ser propositivo e interesante en campos muy diversos y la forma en que cada uno lo hace suyo incorporándolo a su propia investigación proyectual. La silla, más allá de ser un objeto de diseño exclusivamente, trasciende su propia escala para situarse inmersa en un proceso de búsqueda y exploración a nivel conceptual, formal, constructivo y estructural en la arquitectura cada uno de ellos. En un momento en que el oficio del arquitecto está siendo intensamente redefinido considero especialmente pertinente esta investigación, que en definitiva versa sobre la forma distintiva en que el pensamiento arquitectónico es capaz de proyectarse sobre cualquier disciplina para reformularla. ABSTRACT The nineteenth century was a century dedicated to the great public buildings; theaters, schools or museums. However the architecture in the twentieth century was devoted to the study of housing. All uses and typologies were heavily revised but the focus of all efforts and true beginning of modern architecture was housing. From these beginnings all modern precepts were applied to the various programs. Nikolaus Pevsner points to William Morris as the first modern architect precisely because he understood that a truly social art in line with its time and the society it serves must deal with social concerns at that time. With the new housing situation at the center of disciplinary concerns furniture took on a new prominence. At an advanced stage of his career Marcel Breuer observed partly with curiosity, partly with irony how modern furniture had been promoted not by furniture designers but by architects. The answer is given by Le Corbusier in one of his lectures of 1931 collected in Precisions when he pointed the reformulation of furniture as the "Gordian knot" for the renewal of modern plan resolution. Modernism had been forced to confront this issue in order to advance their domestic approaches. Modernism not only put forward a solution to the problems of housing and a Europe under reconstruction but is also needed to be able to contribute to an exciting vision of modern life. Not only did solve existing problems but also it had the self-imposed necessity of anticipating future domesticity and to do their houses full, movable and immovable, they should be submitted under this new image. The founding manifesto of the Deutsche Werkbund extended the scope of the new architect from building cities to the couch cushions. This furniture had the complex mission of synthetically condensing all the ideals of modernity had brought with it: abstraction, hygiene, mechanization, positivist confidence in science or material expression. Objects of modern life, in words of Le Corbusier, were likely to give rise a state of modern life. Few chairs in design history have resulted in so much controversy and so much dispute over their invention as the various versions of cantilevered tubular steel chairs. To understand this let us place ourselves in 1927 at the gates of the exhibition "Die Wohnung" ("Housing") organized by the teachers of the Bauhaus and directed by Mies van der Rohe in Stuttgart Weissenhoflung. Many famous names in architecture at that time showed their personal proposals for modern housing and the objects that inhabit them. Amongst these objects, the steel tube furniture was a constant presence at the exhibition but there was a piece so audacious that it stood out from all the others. This piece in question was the cantilever model chair, that is, which had no further rear support and whose rigidity was attributed to the solidity of its continues structure of steel tube. This piece would eventually become the crossroads of three very different personalities: Mart Stam, Marcel Breuer and Mies van der Rohe. Each of them developed their own model of cantilevered chair in different versions; The MR model developed by Mies van der Rohe, the L&C by Arnold Stam and a later model BR 33 by Marcel Breuer, and the three, at some point in their lives demanded the authorship of its invention as objects that belonged to them intellectually. These chairs epitomized one of the coveted objects of modernity, steel material in its optimized version, was what had led to a completely new form of an everyday object whose this type was fully adopted on board in design. New materials and production methods had burst into world of household objects, and had been able to reformulate their design. The bold design then became a dark object of controversy. The starting point for this doctoral thesis is the concurrent invention of the same model of chair by three different figures of modern architecture. These three architects, who were responsible for ensuring that the modern movement considered construction rather than form as the main design consideration, were working in the same place and at the same point in time. It was almost as if these three architects were shaped by the culture of the time (Zeitgeist). However the focus of this study lies not in an investigation of responsibility of ownership but in the investigation fo how the same object can turn out to be purposeful and interesting in many different fields and the way in which each researcher makes it his own by developing his own project research. 1927, the year of their meeting, was a initiatory year in the career of our players. The chair, beyond being only a design object transcended its own scale and became immersed in a process of research and development on a conceptual, formal, structural and constructive level in the architectural approach of each of the architects. At a time when the role of the architect is being redefined intensely I consider this research, which ultimately concerns the distinctive way the architectural thought can be projected onto and reformulate any discipline, to be particularly relevant.

On the design of a planar phased array radar antenna architecture for space debris situational awareness

The Space Situational Awareness (SSA) program from the European Space Agency (ESA) protects Europe's citizens and their satellite-based services by detecting space hazards. ESA Ground Systems (GS) division is currently designing a phased array radar composed of thousands of radiating elements for future stages of the SSA program [1]. The radar shall guarantee the detection of most of the Low Earth Orbit (LEO) space debris, providing a general map of space junk. While range accuracy is mainly dictated by the radar waveform, the detection and tracking of small objects in LEO regimes is highly dependent on the angular accuracy achieved by the smart phased array antenna, demonstrating the important of the performance of this architecture.

Multisensor data fusion for accurate modelling of mobile objects

In the last decade, multi-sensor data fusion has become a broadly demanded discipline to achieve advanced solutions that can be applied in many real world situations, either civil or military. In Defence,accurate detection of all target objects is fundamental to maintaining situational awareness, to locating threats in the battlefield and to identifying and protecting strategically own forces. Civil applications, such as traffic monitoring, have similar requirements in terms of object detection and reliable identification of incidents in order to ensure safety of road users. Thanks to the appropriate data fusion technique, we can give these systems the power to exploit automatically all relevant information from multiple sources to face for instance mission needs or assess daily supervision operations. This paper focuses on its application to active vehicle monitoring in a particular area of high density traffic, and how it is redirecting the research activities being carried out in the computer vision, signal processing and machine learning fields for improving the effectiveness of detection and tracking in ground surveillance scenarios in general. Specifically, our system proposes fusion of data at a feature level which is extracted from a video camera and a laser scanner. In addition, a stochastic-based tracking which introduces some particle filters into the model to deal with uncertainty due to occlusions and improve the previous detection output is presented in this paper. It has been shown that this computer vision tracker contributes to detect objects even under poor visual information. Finally, in the same way that humans are able to analyze both temporal and spatial relations among items in the scene to associate them a meaning, once the targets objects have been correctly detected and tracked, it is desired that machines can provide a trustworthy description of what is happening in the scene under surveillance. Accomplishing so ambitious task requires a machine learning-based hierarchic architecture able to extract and analyse behaviours at different abstraction levels. A real experimental testbed has been implemented for the evaluation of the proposed modular system. Such scenario is a closed circuit where real traffic situations can be simulated. First results have shown the strength of the proposed system.
