Arquitectura Petite: Charlotte Perriand & Kazuyo Sejima. Una historia transnacional

La tesis revela paralelismos y conexiones entre las arquitectas/diseñadoras Charlotte Perriand (1903-1999) y Kazuyo Sejima (n. 1956), reflejados en una serie de proyectos de pequeña escala que denomino arquitectura petite—mobiliario tecnológico habitable—, resultado de momentos semejantes de cambio social, cultural, económico, industrial y transnacional en Francia en la década de 1920 y en Japón en la década de 1980. Este trabajo dirige su atención a la arquitectura doméstica concebida desde el interior por arquitectos con una formación complementaria en diseño de mobiliario. A su vez, profundiza en la relación que se establece entre el diseño de una casa y el diseño de un mueble, una máquina o un vestido. Los pequeños proyectos, próximos al mobiliario, diseñados por Sejima, no han sido suficientemente estudiados, al igual que los proyectos de arquitectura experimental proyectados por Perriand. Ambas trayectorias analizadas desde estos renovados puntos de vista se encuentran en lo que denominamos arquitectura petite. Surge así un nuevo paradigma espacial en un contexto de poder de lo femenino—en los medios de comunicación—y de intercambio cultural transnacional. Cuando el mobiliario crece y se equipa tecnológicamente para hacerse habitable por un grupo de personas, con cualidades suficientes de confort sensorial, es arquitectura petite. En 2009, Toyo Ito mostró en una conferencia en Madrid, una imagen de Sejima posando en su proyecto Pao I. Justo ochenta años antes, en 1929, Le Corbusier presentó en Buenos Aires la imagen de Perriand posando para su Chaise Longue. La coincidencia de ambas fotografías, junto con la lectura de dos inspiradores artículos de Toyo Ito, “Adèle’s dream” (1984)—cuyo enigmático título utiliza un nombre francés femenino para describir una casa japonesa—y “Simple lines for Le Corbusier” (1994), dieron origen a la hipótesis central de una investigación: la comparación de dos arquitectas, sus maestros y dos objetos pertenecientes a dos momentos y lugares distantes. Perriand y Sejima fueron emblemas del concepto de Nueva Feminidad, ambas tenían éxito en la prensa generalista del momento antes de ser contratadas por Le Corbusier y Toyo Ito respectivamente. Junto a sus maestros de entonces, concibieron dos iconos de la era de la maquina y de la electrónica respectivamente, la Chaise Longue (1928) y Pao I (1985), diseñados para ellas mismas. Perriand y Sejima usaron su propio cuerpo como unidad de medida y su imagen como reclamo publicitario para la promoción de los dos objetos respectivamente. La precisión técnica, materiales de lujo y enfoque de la relajación que compartieron la Chaise Longue y Pao I sugirió un nomadismo lúdico que anticipó el desarrollo posterior de lo que denominamos de arquitectura petite por parte de Perriand y Sejima. Ambos prototipos son los antecedentes de una arquitectura de talla precisa o petite (objetos híbridos entre casa, mueble y máquina con la sensualidad como característica distintiva) que ambas arquitectas han proyectado a lo largo de su carrera, y que aúnan su interés mutuo por las propiedades físicas de los materiales, así como su formación en diseño de mobiliario y su fascinación por la moda. La tesis concluye que la arquitectura petite es la depositaria de los manifiestos de una época, la que sigue a la era de la máquina enunciada por Le Corbusier y a la era de la electrónica descrita por Toyo Ito. En este sentido, la tesis evidencia la forma en la que importantes arquitectos han concentrado ideas ambiciosas en pequeños proyectos. Las características de petite se resumen en el hecho de ser una arquitectura de límites precisos, desmontable y por tanto temporal, que explora el potencial técnico y formal de nuevos materiales importados de otras industrias, incorpora condiciones sensuales propias de su escala antropométrica, y está destinada al ocio de un grupo de personas. A modo de colofón, la tesis descubre la existencia de una historia de ficción que vincula a Charlotte Perriand y Kazuyo Sejima a través de Toyo Ito: “El diario de Adèle”. ABSTRACT This dissertation reveals parallels between the architects/designers Charlotte Perriand (1903- 1999) and Kazuyo Sejima (b. 1956), reflected in a series of small projects I call petite architecture—habitable technological furniture—, which formed during similar periods of social, cultural, economic, industrial and transnational change in France in the 1920s and in Japan in the 1980s. This research focuses on domestic architecture conceived from the inside by architects with additional training in furniture design. At the same time, it explores the relationships established between the design of a house, a piece of furniture, a machine, or a dress. Small architectural projects, close to the furniture, designed by Sejima have not been sufficiently studied, as well as the experimental architectural projects designed by Perriand. Both of their experimental trajectories analyzed from this renovated point of view converge on what we call petite architecture. Thus, it raises a new spatial paradigm in the context of feminine power within the media, as direct consumers, and transnational cultural exchange. When furniture expands and is technologically equipped to the point where it becomes habitable by a group, or groups of people, providing its occupants with sensorial comfort, it is petite architecture. In 2009, at a conference in Madrid, Ito showed a picture of Sejima posing at his Pao I (1985). Just eighty years earlier, in 1929, Le Corbusier exhibited in a conference in Buenos Aires an image of Perriand posing for his Chaise Longue (1928). The coincidence of the two photographs, along with two inspiring articles by Toyo Ito "Adèle's dream" (1984) — whose enigmatic title uses a French female name to describe a Japanese house — and "Simple lines for Le Corbusier" (1994) led to a hypothesis and an investigation comparing the two architects, their mentors, and two objects, each belonging to two distant times and places. Perriand and Sejima were emblems of the concept of New Femininity, both had success in the media of their time before being hired by Le Corbusier and Toyo Ito respectively. Together with their mentors they designed two objects that became icons of the Machine Age and the Electronic Age respectively: the Chaise Longue (1928) and Pao I (1985). Designed "for themselves," Perriand and Sejima used their own bodies as a measuring unit and their image as a publicity stunt to promote the two objects respectively. Both objects are the embryonic capsules of the architecture that pampers the scale or petite (objects that conflate residence, machine and furniture, and have sensuality as a distinctive feature). From the technical precision, luxurious materials, and approach towards relaxation, emerged a playful nomadism, which anticipated the further development of what we call petite architecture. Perriand and Sejima would develop these ideas throughout their career, pooling their interests on the physical properties of materials, formation in furniture design, and their intense interest in fashion. The dissertation concludes that petite architecture is the manifestation of an age, which follows the Machine Age defined by Le Corbusier and the Electronic Age described by Toyo Ito. In this sense, the dissertation demonstrates the way in which important architects have focused their ambitious ideas on small projects. petite characteristics are summarized as being: architecture that pampers the scale, is (de)mountable and therefore temporary, explores the formal and technical potential of novel materials and techniques imported from other industries, incorporates sensual conditions according with its anthropometric scale, and is conceived for the leisure of a group of people. In addition, by way of colophon, the dissertation discovers the existence of a fictional story that links Charlotte Perriand and Kazuyo Sejima through Toyo Ito: "Adèle's Diary".

Habitar lo irreal. aproximaciones a una arquitectónica de los mundos virtuales

Lo virtual es el lugar donde todo empieza, el germen de la imaginación productiva, un ámbito de pulsiones inaugurales y preexistencias sin forma donde todo convive, a la espera de ser diferenciado. Lo virtual es el sitio donde nacen las primeras exploraciones de cualquier acto de concepción, incluida la creación artística o el proyectar arquitectónico. Sin embargo, en las últimas tres décadas de revolución digital, el término ha sido utilizado de forma abusiva para referirse a todo tipo de entornos simulados informáticamente, es decir, a ficciones cerradas, programadas, controladas por el software y sus rutinas, radicalmente actualizadas, acabadas, completas, formalizadas. Paradójicamente, lo virtual ha servido para nombrar construcciones profundamente anti-virtuales. La telemática está propiciando el acceso del ser humano a un nuevo tipo de irrealidad cotidiana sustentada en prácticas espaciales cada vez menos vinculadas con la física y la biología. Esta condición fantasmagórica del habitar digital exige nuevos espacios de diálogo entre arquitectura y tecnología que se centren en el hecho imaginario. Para ello esta tesis propone —a partir de la recuperación del término griego arquitectónica— llevar el alcance de la disciplina hasta el hecho global del habitar. Y, al mismo tiempo, devolver al adjetivo virtual su auténtico significado preliminar, entendiendo que los verdaderos mundos virtuales no pueden simular nada, representar nada, formalizar nada, porque ellos son el origen infinito y amorfo de todo mundo. ABSTRACT The virtual is where it all starts, the seed of productive imagination, an area of inaugural impulses and formless preexistences that beat together, waiting to be differentiated. The virtual is the birthplace of any creative exploration, including those of the architectural project. However, in the last three decades of digital revolution, the term has been mostly misused to refer to all types of computer simulated environments; shut, finished, complete, formalized, radically actualized fictions controlled by software routines. Paradoxically, the virtual has been giving name to profoundly anti-virtual constructions. Telematics is allowing humans to access to a new kind of unreality, based on everyday spatial practices that are increasingly detached from physics and biology. This spectral condition of the digital living demands new dialectics between architecture and technology, focused on the imaginary. This thesis proposes — beginning by recovering the Greek word architectonics— to extend the scope of the discipline beyond edification to the overall fact of inhabiting. And, at the same time, to return to the adjective virtual its authentic preliminary meaning, realizing that the true virtual worlds cannot simulate, represent or formalize anything because they are the amorphous and endless source of every world.

Semi-supervised subspace clustering and applications to neuroscience

Machine learning techniques are used for extracting valuable knowledge from data. Nowa¬days, these techniques are becoming even more important due to the evolution in data ac¬quisition and storage, which is leading to data with different characteristics that must be exploited. Therefore, advances in data collection must be accompanied with advances in machine learning techniques to solve new challenges that might arise, on both academic and real applications. There are several machine learning techniques depending on both data characteristics and purpose. Unsupervised classification or clustering is one of the most known techniques when data lack of supervision (unlabeled data) and the aim is to discover data groups (clusters) according to their similarity. On the other hand, supervised classification needs data with supervision (labeled data) and its aim is to make predictions about labels of new data. The presence of data labels is a very important characteristic that guides not only the learning task but also other related tasks such as validation. When only some of the available data are labeled whereas the others remain unlabeled (partially labeled data), neither clustering nor supervised classification can be used. This scenario, which is becoming common nowadays because of labeling process ignorance or cost, is tackled with semi-supervised learning techniques. This thesis focuses on the branch of semi-supervised learning closest to clustering, i.e., to discover clusters using available labels as support to guide and improve the clustering process. Another important data characteristic, different from the presence of data labels, is the relevance or not of data features. Data are characterized by features, but it is possible that not all of them are relevant, or equally relevant, for the learning process. A recent clustering tendency, related to data relevance and called subspace clustering, claims that different clusters might be described by different feature subsets. This differs from traditional solutions to data relevance problem, where a single feature subset (usually the complete set of original features) is found and used to perform the clustering process. The proximity of this work to clustering leads to the first goal of this thesis. As commented above, clustering validation is a difficult task due to the absence of data labels. Although there are many indices that can be used to assess the quality of clustering solutions, these validations depend on clustering algorithms and data characteristics. Hence, in the first goal three known clustering algorithms are used to cluster data with outliers and noise, to critically study how some of the most known validation indices behave. The main goal of this work is however to combine semi-supervised clustering with subspace clustering to obtain clustering solutions that can be correctly validated by using either known indices or expert opinions. Two different algorithms are proposed from different points of view to discover clusters characterized by different subspaces. For the first algorithm, available data labels are used for searching for subspaces firstly, before searching for clusters. This algorithm assigns each instance to only one cluster (hard clustering) and is based on mapping known labels to subspaces using supervised classification techniques. Subspaces are then used to find clusters using traditional clustering techniques. The second algorithm uses available data labels to search for subspaces and clusters at the same time in an iterative process. This algorithm assigns each instance to each cluster based on a membership probability (soft clustering) and is based on integrating known labels and the search for subspaces into a model-based clustering approach. The different proposals are tested using different real and synthetic databases, and comparisons to other methods are also included when appropriate. Finally, as an example of real and current application, different machine learning tech¬niques, including one of the proposals of this work (the most sophisticated one) are applied to a task of one of the most challenging biological problems nowadays, the human brain model¬ing. Specifically, expert neuroscientists do not agree with a neuron classification for the brain cortex, which makes impossible not only any modeling attempt but also the day-to-day work without a common way to name neurons. Therefore, machine learning techniques may help to get an accepted solution to this problem, which can be an important milestone for future research in neuroscience. Resumen Las técnicas de aprendizaje automático se usan para extraer información valiosa de datos. Hoy en día, la importancia de estas técnicas está siendo incluso mayor, debido a que la evolución en la adquisición y almacenamiento de datos está llevando a datos con diferentes características que deben ser explotadas. Por lo tanto, los avances en la recolección de datos deben ir ligados a avances en las técnicas de aprendizaje automático para resolver nuevos retos que pueden aparecer, tanto en aplicaciones académicas como reales. Existen varias técnicas de aprendizaje automático dependiendo de las características de los datos y del propósito. La clasificación no supervisada o clustering es una de las técnicas más conocidas cuando los datos carecen de supervisión (datos sin etiqueta), siendo el objetivo descubrir nuevos grupos (agrupaciones) dependiendo de la similitud de los datos. Por otra parte, la clasificación supervisada necesita datos con supervisión (datos etiquetados) y su objetivo es realizar predicciones sobre las etiquetas de nuevos datos. La presencia de las etiquetas es una característica muy importante que guía no solo el aprendizaje sino también otras tareas relacionadas como la validación. Cuando solo algunos de los datos disponibles están etiquetados, mientras que el resto permanece sin etiqueta (datos parcialmente etiquetados), ni el clustering ni la clasificación supervisada se pueden utilizar. Este escenario, que está llegando a ser común hoy en día debido a la ignorancia o el coste del proceso de etiquetado, es abordado utilizando técnicas de aprendizaje semi-supervisadas. Esta tesis trata la rama del aprendizaje semi-supervisado más cercana al clustering, es decir, descubrir agrupaciones utilizando las etiquetas disponibles como apoyo para guiar y mejorar el proceso de clustering. Otra característica importante de los datos, distinta de la presencia de etiquetas, es la relevancia o no de los atributos de los datos. Los datos se caracterizan por atributos, pero es posible que no todos ellos sean relevantes, o igualmente relevantes, para el proceso de aprendizaje. Una tendencia reciente en clustering, relacionada con la relevancia de los datos y llamada clustering en subespacios, afirma que agrupaciones diferentes pueden estar descritas por subconjuntos de atributos diferentes. Esto difiere de las soluciones tradicionales para el problema de la relevancia de los datos, en las que se busca un único subconjunto de atributos (normalmente el conjunto original de atributos) y se utiliza para realizar el proceso de clustering. La cercanía de este trabajo con el clustering lleva al primer objetivo de la tesis. Como se ha comentado previamente, la validación en clustering es una tarea difícil debido a la ausencia de etiquetas. Aunque existen muchos índices que pueden usarse para evaluar la calidad de las soluciones de clustering, estas validaciones dependen de los algoritmos de clustering utilizados y de las características de los datos. Por lo tanto, en el primer objetivo tres conocidos algoritmos se usan para agrupar datos con valores atípicos y ruido para estudiar de forma crítica cómo se comportan algunos de los índices de validación más conocidos. El objetivo principal de este trabajo sin embargo es combinar clustering semi-supervisado con clustering en subespacios para obtener soluciones de clustering que puedan ser validadas de forma correcta utilizando índices conocidos u opiniones expertas. Se proponen dos algoritmos desde dos puntos de vista diferentes para descubrir agrupaciones caracterizadas por diferentes subespacios. Para el primer algoritmo, las etiquetas disponibles se usan para bus¬car en primer lugar los subespacios antes de buscar las agrupaciones. Este algoritmo asigna cada instancia a un único cluster (hard clustering) y se basa en mapear las etiquetas cono-cidas a subespacios utilizando técnicas de clasificación supervisada. El segundo algoritmo utiliza las etiquetas disponibles para buscar de forma simultánea los subespacios y las agru¬paciones en un proceso iterativo. Este algoritmo asigna cada instancia a cada cluster con una probabilidad de pertenencia (soft clustering) y se basa en integrar las etiquetas conocidas y la búsqueda en subespacios dentro de clustering basado en modelos. Las propuestas son probadas utilizando diferentes bases de datos reales y sintéticas, incluyendo comparaciones con otros métodos cuando resulten apropiadas. Finalmente, a modo de ejemplo de una aplicación real y actual, se aplican diferentes técnicas de aprendizaje automático, incluyendo una de las propuestas de este trabajo (la más sofisticada) a una tarea de uno de los problemas biológicos más desafiantes hoy en día, el modelado del cerebro humano. Específicamente, expertos neurocientíficos no se ponen de acuerdo en una clasificación de neuronas para la corteza cerebral, lo que imposibilita no sólo cualquier intento de modelado sino también el trabajo del día a día al no tener una forma estándar de llamar a las neuronas. Por lo tanto, las técnicas de aprendizaje automático pueden ayudar a conseguir una solución aceptada para este problema, lo cual puede ser un importante hito para investigaciones futuras en neurociencia.

News in engineering education in Spain effective from 2010 in presence of external changes and mixed crisis, looking mostly to agro and civil engineers.

The engineering careers models were diverse in Europe, and are adopting now in Spain the Bolonia process for European Universities. Separated from older Universities, that are in part technically active, Civil Engineering (Caminos, Canales y Puertos) started at end of 18th century in Spain adopting the French models of Upper Schools for state civil servants with exam at entry. After 1800 intense wars, to conserve forest regions Ingenieros de Montes appeared as Upper School, and in 1855 also the Ingenieros Agrónomos to push up related techniques and practices. Other Engineers appeared as Upper Schools but more towards private factories. These ES got all adapted Lower Schools of Ingeniero Tecnico. Recently both grew much in number and evolved, linked also to recognized Professions. Spanish society, into European Community, evolved across year 2000, in part highly well, but with severe discordances, that caused severe youth unemployment with 2008-2011 crisis. With Bolonia process high formal changes step in from 2010-11, accepted with intense adaptation. The Lower Schools are changing towards the Upper Schools, and both that have shifted since 2010-11 various 4-years careers (Grado), some included into the precedent Professions, and diverse Masters. Acceptation of them to get students has started relatively well, and will evolve, and acceptation of new grades for employment in Spain, Europe or outside will be essential. Each Grado has now quite rigid curricula and programs, MOODLE was introduced to connect pupils, some specific uses of Personal Computers are taught in each subject. Escuela de Agronomos centre, reorganized with its old name in its precedent buildings at entrance of Campus Moncloa, offers Grados of Agronomic Engineering and Science for various public and private activities for agriculture, Alimentary Engineering for alimentary activities and control, Agro-Environmental Engineering more related to environment activities, and in part Biotechnology also in laboratories in Campus Monte-Gancedo for Biotechnology of Plants and Computational Biotechnology. Curricula include Basics, Engineering, Practices, Visits, English, ?project of end of career?, Stays. Some masters will conduce to specific professional diploma, list includes now Agro-Engineering, Agro-Forestal Biotechnology, Agro and Natural Resources Economy, Complex Physical Systems, Gardening and Landscaping, Rural Genie, Phytogenetic Resources, Plant Genetic Resources, Environmental Technology for Sustainable Agriculture, Technology for Human Development and Cooperation.

Optimisation of algorithms to compute information theoretic indexes

Analysis of big amount of data is a field with many years of research. It is centred in getting significant values, to make it easier to understand and interpret data. Being the analysis of interdependence between time series an important field of research, mainly as a result of advances in the characterization of dynamical systems from the signals they produce. In the medicine sphere, it is easy to find many researches that try to understand the brain behaviour, its operation mode and its internal connections. The human brain comprises approximately 1011 neurons, each of which makes about 103 synaptic connections. This huge number of connections between individual processing elements provides the fundamental substrate for neuronal ensembles to become transiently synchronized or functionally connected. A similar complex network configuration and dynamics can also be found at the macroscopic scales of systems neuroscience and brain imaging. The emergence of dynamically coupled cell assemblies represents the neurophysiological substrate for cognitive function such as perception, learning, thinking. Understanding the complex network organization of the brain on the basis of neuroimaging data represents one of the most impervious challenges for systems neuroscience. Brain connectivity is an elusive concept that refers to diferent interrelated aspects of brain organization: structural, functional connectivity (FC) and efective connectivity (EC). Structural connectivity refers to a network of physical connections linking sets of neurons, it is the anatomical structur of brain networks. However, FC refers to the statistical dependence between the signals stemming from two distinct units within a nervous system, while EC refers to the causal interactions between them. This research opens the door to try to resolve diseases related with the brain, like Parkinson’s disease, senile dementia, mild cognitive impairment, etc. One of the most important project associated with Alzheimer’s research and other diseases are enclosed in the European project called Blue Brain. The center for Biomedical Technology (CTB) of Universidad Politecnica de Madrid (UPM) forms part of the project. The CTB researches have developed a magnetoencephalography (MEG) data processing tool that allow to visualise and analyse data in an intuitive way. This tool receives the name of HERMES, and it is presented in this document. Analysis of big amount of data is a field with many years of research.

Use of Headed Reinforcement Bars in Contruction. A Theoretical Approach to Determine the Dimensions of Anchorage Plates and Experimental Tests on Knee Joints Subjected to a Closing Moment

In order to reduce costs and time while improving quality, durability and sustainability in structural concrete constructions, a widely used material nowadays, special care must be taken in some crucial phases of the project and execution, including the structure design and calculation, the dosage, dumping and curing of concrete: another important aspect is the proper design and execution of assembly plans and construction details. The framework, a name designating the whole reinforcement bars cage already assembled as shown in the drawings, can be made up of several components and implies higher or lower industrialization degree. The framework costs constitute about one third of the price per cubic meter placed in concrete works. The best solutions from all points of view are clearly those involving an easier processing to achieve the same goal, and consequently carrying a high degree of industrialization, meaning quality and safety in the work. This thesis aims to provide an indepth analysis of a relatively new type of anchoring by plate known as headed reinforcement bars, which can potentially replace standard or L-shaped hooks, improving the cleaning of construction details and enabling a faster, more flexible, and therefore a more economical assembly. A literature review on the topic and an overview of typical applications is provided, followed by some examples of specific applications in real projects. Since a strict theoretical formulation used to provide the design plate dimensions has not yet been put forward, an equation is proposed for the side-face blowout strength of the anchorage, based on the capacity of concrete to carry concentrated loads in cases in which no transverse reinforcement is provided. The correlation of the calculated ultimate load with experimental results available in the literature is given. Besides, the proposed formulation can be expanded to cases in which a certain development length is available: using a software for nonlinear finite element analysis oriented to the study of reinforced concrete, numerical tests on the bond-bearing interaction are performed. The thesis ends with a testing of eight corner joints subjected to a closing moment, held in the Structures Laboratory of the Polytechnic University of Madrid, aiming to check whether the design of such plates as stated is adequate for these elements and whether an element with plate-anchored reinforcement is equivalent to one with a traditional construction detail.

Artefactos energéticos : de Fuller a Piñero (1961-1972) = Energetic artefacts : from Fuller to Piñero (1961-1972)

La obra de Emilio Pérez Piñero que se desarrolla entre los años 1961 y 1972 año en el que muere en un accidente de tráfico volviendo de Figueras, se centra principalmente en artefactos desplegables y desmontables, ejecutando prototipos que en el presente trabajo se han dividido en dos grupos; la cúpula reticular y la infraestructura. No pudo por tanto acudir al Congreso de 1972 de la UIA a recoger el premio Auguste Perret a la innovación tecnológica, que en años anteriores habían recibido Félix Candela, Jean Prouvé, Hans Scharoun o Frei Otto, y que en aquella ocasión tuvo que recoger su viuda. Parámetros como el de la movilidad, indeterminación, intercambiabilidad, obsolescencia y otros que se analizan en el presente trabajo, aparecen a lo largo de toda su obra ya que muchos de sus artefactos están ubicados en no-lugares y tienen un carácter itinerante y por tanto se hace indispensable su rápido montaje y desmontaje, que unas veces se resuelve mediante la desmontabilidad y otras con la plegabilidad de éstos. Aunque pueda parecer Piñero una figura autárquica, lo cierto es que durante la década donde concentra su trabajo se produce una explosión en torno a al arquetipo que será denominado de forma genérica `artefacto´, ligado conceptualmente a los parámetros que aquí se definen. Entendemos artefacto como objeto material realizado por una o varias personas para cumplir una función, es sinónimo de máquina y aparato y deriva de las palabras latinas ars o artis (técnica) y facto (hecho), para designar a los objetos cuya fabricación requiere alguna destreza. El término latino `ars´ engloba a las técnicas y a las artes, lo que no ocurre con el término castellano arte que deriva de él. Los movimientos utópicos que comparte la década con Piñero, utilizan el arquetipo infraestructural, ligero y high tech, para a través de una arquitectura más ligada a la ciencia ficción, realizar una crítica al Movimiento Moderno institucionalizado, todos ellos comparten cierta obsesión por la movilidad, ligada ésta a la idea de espacio flexible, dinámico, nómada. Este concepto de neo-nomadismo, que representa un habitar dinámico, aglutina las nuevas formas de vivir donde la movilidad social y geográfica son habituales. El nomadismo, por otra parte se entiende como sinónimo de democracia y libertad. La arquitectura pasa de ser pesada, estática, permanente a ser un elemento dinámico en continuo movimiento. A veces con connotaciones biológicas se asimilan los artefactos a organismos vivos y les confieren dichas propiedades de crecimiento y autonomía energética, acumulándose en torno a megaestructuras, donde quedan `enchufados´. En este intento de dotar movilidad a lo inmueble, se buscan estructuras vivas y modificables que crecen en una asimilación de las leyes naturales utilizando los parámetros de metamorfosis, simbiosis y cambio. Estos movimientos de vanguardia tienen también ciertas connotaciones políticas y sociales basadas en la libertad y la movilidad y reniegan del consumismo institucionalizado, de la arquitectura como instrumento de consumo, como objeto de usar en la cultura de masas. El carácter político de la autogestión, de la customización como parámetro proyectual, de la autosuficiencia energética, que anticipa la llegada de la crisis energética del año 1973. Objeto de este trabajo será relacionar los conceptos que aparecen fuertemente en el entorno de la década de los años sesenta del siglo XX, en el trabajo de Emilio Pérez Piñero. Parámetros encontrados como conceptos en los grupos de vanguardia y utopía a su vez fuertemente influenciados por las figuras del ingeniero Richard Buckminster Fuller y del arquitecto Konrad Wachsmann. Se analizará que posible influencia tiene la obra de Fuller, principalmente el prototipo denominado cúpula reticular, en la obra de Pérez Piñero y sus coetáneos analizando sus pensamientos teóricos en torno a parámetros como la energía, principalmente en las teorías relativas a Synergetics. El término inventado por Richard B. Fuller es una contracción de otro más largo que en inglés agrupa tres palabras; synergetic-energetic geometry. La definición de sinergia es la cooperación, es decir es el resultado de la acción conjunta de dos o más causas, pero con un efecto superior a la suma de estas causas. El segundo término, energetics geometry, que traducido sería geometría energética hace referencia en primer lugar a la geometría; ya que desarrolla el sistema de referencia que utiliza la naturaleza para construir sus sistemas y en segundo lugar a la energía; ya que además debe ser el sistema que establezca las relaciones más económicas utilizando el mínimo de energía. Por otro lado se analiza la repercusión del prototipo denominado Infraestructura, término acuñado por Yona Friedman y basado estructuralmente y conceptualmente en los desarrollos sobre grandes estructuras de Konrad Wachsmann. El arquitecto alemán divulga su conocimiento en seminarios impartidos por todo el mundo como el que imparte en Tokio y se denomina Wachsmann´s Seminar donde participan algunos de los componentes del grupo Metabolista que sorprenderán al mundo con sus realizaciones en la exposición de Osaka de 1970. El intervalo temporal entre 1961 hasta 1972 hace referencia a la horquilla donde Pérez Piñero realiza su obra arquitectónica, que comienza en 1961 cuando gana el concurso convocado en Londres por la UIA (Unión Internacional de Arquitectos) con el proyecto conocido como Teatro Ambulante, hasta 1972 que es cuando fallece volviendo de Figueras donde está realizando dos encargos de Salvador Dalí; la cubrición del escenario del futuro Teatro-Museo Salvador Dalí y la Vidriera Hipercúbica que debía cerrar la boca de tal escenario. Bajo el título de `Artefactos energéticos. De Fuller a Piñero (1961-1972)´, se presenta esta Tesis doctoral, que tiene la intención de vincular la obra de Emilio Pérez Piñero con la de las neo vanguardias producidas por una serie de arquitectos que operan en el ámbito internacional. Estas vinculaciones se producen de una forma general, donde a través de una serie de estrategias según la metodología que posteriormente se describe se buscan relaciones de la obra del autor español con algunos de los movimientos más significativos que aparecen en dicha década y de manera específica estableciendo relaciones con las obras y pensamientos de los autores que pertenecen a estos movimientos y donde estas relaciones se hacen más evidentes. El objeto del presente trabajo es analizar y explicar la obra del arquitecto Emilio Pérez Piñero, que espacialmente se localiza en el territorio español, desde el punto de vista de estos movimientos para posteriormente poder determinar si existen puntos en común y si el arquitecto español no solo comparte la década temporalmente sino también conceptualmente y por tanto utiliza el ideario que utilizan sus coetáneos que forman parte de las neovanguardias de los años sesenta de siglo XX. ABSTRACT ABSTRACT The Work of Emilio Perez Piñero was developed between the years 1961 and 1972 when he died in a car accident coming back from Figueres, where he was building a geodesic dome to close the building that enclose the Dali’s museum. All his Work is mainly centered in artifact that could be collapsible and removable, taking the two prototypes that are described in this work as a recurrent element in all his creation. These are the reticular dome and the infrastructure that are very influenced by the work from Richard B. Fuller and Konrad Wachsmann. Emilio Pérez Piñero could not receive the Auguste Perret Prize in 1972 awarded by the UIA that years before have received architects as Felix Candela, Jean Prouvé, Hans Scharoun or Frei Otto, and this time Pérez Piñero´s wife will accept it because of his death. Parameters like mobility, changeability, expendability, indetermination and others appear currently in his Work. All the inventions that Piñero had been patented and all of the artifacts that he created are usually located in no-places, because they do have a shifting identity. This kind of building has to be quickly set on site, and this problem has to be solved in term of foldability or demounting. In the decade where his work focuses, an explosion has occurred around this archetype to be generally called artifact that is usually linked to mobility. We understand artifact as a material object made by one or more people to work in a particular way. It is sometimes equated with the terms machinery and apparatus and it is derived from the Latin word `ars´ or `artis´, what means techniques and `facto´ (fact). And we use this term to refer to objects whose manufacture requires the same skill, in fact the Latin word `ars´ covers the techniques and arts, which does not occur with the Castillan term `arte´ that derives from it and means only art. The term neo-nomadic is a relatively new name used for a dynamic life, commonly referred to new forms of life where social and geographical mobility are common. On the other hand nomadic could be understood as a synonymous for democracy and freedom. The architecture is not going to be hard and static anymore but a dynamic element in the move. The Neo-avant-garde movement that shares the decade with Piñero uses this infrastructural archetype, which is light and high-tech, to criticize the institutionalized Modern Movement through architecture linked to science fiction. They all share an obsession with mobility, a concept that is connected to the terms `dynamic´, `nomadic´, `flexibile´, etc. Sometimes, with biological connotations, the utopian assimilate the artifacts to living organisms and give them these properties of growth and energy autonomy, and they apparently grow around megastructures where they are plugged. In this attempt to provide mobility to the inertness, living structures and possibility of change are sought in order to make them grow like a living organism and to assimilate the natural laws of growth. According to a definition from architecture provided by Fernández- Galiano who calls it `exosomatic artifact´, he understand architecture as artifact of the human environment that regulates natural energy flows and channels the energy stored in fuels for the benefit of living beings that inhabit. It is also true that during the sixties a new environmental awareness in public opinion is formed and that is due to the exploitation and disproportionate use of energy resources, acceleration of technological processes and mass consumption. Consequently a new concept is born: energy autonomy, it is very close to rational use of natural energy. Such a concept will be culturally assimilated with the requirement of independence not only in the management but also in the building construction until we arrive at energy autonomy. The individuals become energy consumer, which in turn can enter the energy produced in the system to `life in an eco-mode way´. The objectives of this research are analyzing all of these parameters and concepts that are coming into view in the surrounding of the decade and relate them with the Work of Pérez Piñero. Terms strongly present in the avant-garde movements around the decade, a young architect’s generation strongly influenced by Richard B. Fuller and Konrad Wachsmann. However, it will be analyzed how important the influence of Buckminster Fuller's Work was and his theoretical text about energy on the Work of Pérez Piñero and his fellows of the decade. The term Synergetic was invented by Fuller and came from the words synergy and energetic geometry. Synergy is the cooperation or interaction of two or more agents to produce a greater effect than the sum of their separate effects. Energetic geometry is related to the geometries that the Nature is using to build their construction but always using low energy consumption. On the other hand, the influences from Wachsmann around the prototype called Infrastructure have been analyzed. The German architect has developed knowledge around huge structures that he has spread all around the world through seminars that he has been conducted. One of these was the Wachsmann´s seminar in Tokyo, where same of the members of the Metabolist group were taking part of. Later these young architects will surprise the world with his artifacts at the World Exposition in Osaka in 1970. Between 1961 and 1972 Pérez Piñero produced his architectural work. It began in 1961 when he received the first prize with his project Mobile Theatre in the competition organized by the UIA in London. In 1972 the Auguste Perret Prize was granted by the UIA too. He could not accept it because he died before in a car accident when he was coming from Figueres, when he was designing two projects for Dali. With the title `Energetic Artifacts. From Fuller to Piñero (1961- 1972)´, this thesis relates the Work of Emilio Pérez Piñero with the neo avant-garde made by a young architects’ generation who is sharing the time with him. Several strategies have been used to formed relationships between them. They are described in the present work to set up a method that allows us to relate the work and ideas of the architects of the neo avant-garde with the ones from Piñero. This work is intended to analyze and explained the work of Pérez Piñero from the point of view of the international architects’ generation who is operating at the same time and finally to determinate if Piñero is not sharing the time with them but the concepts, ideas and architectural parameters.
