Al Este del Retiro

La zona de Madrid al Este del Retiro ha estado indefectiblemente condicionada en su tardío desarrollo urbano por su posición a espaldas del Real Sitio. La construcción hacia 1640 de las tapias que rodeaban los reales jardines transformó la red de caminos que partían hacia oriente, aisló los terrenos ubicados más al Este de la ciudad, con la que ya sólo se podrían comunicar por las carreteras de Aragón y Valencia, y condenó las expectativas de desarrollo urbano reduciendo los precios de las propiedades, lo cual determinó durante décadas los usos y la arquitectura de la zona. El Anteproyecto de Ensanche de Carlos María de Castro constituye el germen a partir del cual, durante un lento proceso de casi cien años, fue configurándose la ciudad que hoy conocemos. La identificación en el Archivo de Villa del primer plano general del Ensanche trazado por Castro, del cual anteriores trabajos advirtieron de su existencia aunque se desconocía su localización, es la principal aportación de esta investigación. Por un lado, este primer plano general del Ensanche manuscrito es, por sí mismo, un documento de indudable importancia en la historia del urbanismo madrileño. En segundo lugar, el análisis de su contenido arroja nueva luz sobre la propuesta original de Castro, parcialmente censurada por la Dirección General de Obras Públicas antes de la aprobación del plan en 1860. Especialmente en lo referente a la zona de Madrid al Este del Retiro, proyectada como barrio obrero del Ensanche, este documento ha aportado un enfoque desconocido hasta ahora sobre el paisaje urbano concebido por Castro para la más ambiciosa propuesta planteada en mucho tiempo al problema de la vivienda obrera. Finalmente, el análisis de la factura del plano revela la superposición de varias capas de dibujo, evidenciando que durante un tiempo fue un documento vivo, utilizado como plano de trabajo por el equipo de Castro durante aproximadamente diez años, hasta la destitución del ingeniero en 1868. Posteriores análisis del plano sobre otros ámbitos de la ciudad arrojarán sin duda nuevos datos sobre el proceso proyectual del conjunto del Ensanche. Pero la dinámica de lo real, sintetizable en múltiples factores de índole social, económica y legislativa, transformó durante las primeras décadas de andadura del Ensanche la ciudad proyectada por Castro al Este del Retiro. El dibujo de la ciudad, entendido como herramienta de análisis y empleado con éxito en trabajos de investigación realizados por otros autores en la misma línea, ha permitido deducir la reconstitución gráfica del estado de la ciudad en diferentes momentos singulares del desarrollo urbanístico de la zona, así como de la propuesta original de barrio obrero de Castro. No hay que olvidar que, a pesar del escaso interés que suscitaba entre los inversores inmobiliarios el ámbito geográfico de estudio de esta tesis, fue objeto, durante casi un siglo, de numerosas propuestas de ordenación y urbanización que, aunque no llegaron a materializarse, fueron configurando una suerte de desarrollo virtual de la ciudad paralelo al devenir de la realidad. De esta forma, el dibujo se constituye en esta tesis como fuente de información, herramienta de pensamiento y resultado de la investigación en sí mismo, ilustrando y contribuyendo al mejor conocimiento de la forma urbana. ABSTRACT The area of Madrid to the East of the Retiro has been inevitably conditioned in its late urban development by its position behind the Royal Site. The construction of the walls surrounding the royal gardens around 1640 transformed the network of roads departing eastward, isolated land located to the East of the city, with which already only could communicate by roads of Aragon and Valencia, condemned the expectations of urban development by reducing the prices of the properties, and determined for decades uses and architecture of the area. The Carlos María de Castro preliminary design of City Expansion is the germ from which, during a slow process of almost one hundred years, the city which we know today was setting up. The discovery in the City Archive of the City Expansion first drawing traced by Castro, which previous investigations warned of its existence although its location was unknown, is the main contribution of this research. Firstly, this hand drawn general plan of the city expansion is by itself a document of undoubted importance in the history of Madrid urbanism. Secondly, the analysis of its content sheds new light on Castro´s original proposal, partially censored by the Dirección General de Obras Públicas before the approval of the plan in 1860. Especially concerning the area of Madrid to the East of the Retiro, projected as a workingclass district of the City Expansion, this document has provided an unknown up to now approach on the urban landscape designed by Castro for the more ambitious proposal put forward in a long time to the problem of worker housing. Finally, analysis of hand drawn plan reveals the superposition of several layers of drawing, demonstrating that for a time it was a living document, used as a work plan by the Castro team for approximately ten years, until the dismissal of the engineer in 1868. Subsequent analysis of the drawing on other areas of the city will have no doubt new data on the design process of the whole City Expansion. But the dynamics of reality, synthesizable on multiple factors in social, economic and legislative, transformed during the first decades of existence of the City Expansion designed by Castro to the East of the Retiro. Drawing of the city, understood as a tool of analysis and used successfully in research works done by other authors on the same line, has allowed to deduct graphic reconstitution of the city status in different and singular moments in the urban development of the area, as well as the original Castro´s proposal of working-class district. It should not be forgotten that, despite the lack of interest which raised among investors the geographic scope of this thesis study, it was the object, for nearly a century, of numerous proposals for urbanization which, although they didn´t materialize, were setting up a sort of virtual development of the city parallel to the becoming of the reality. In this way, drawing is used in the thesis as a source of information, tool of thought and outcome of the research itself, illustrating and contributing to a better understanding of urban form.

Virtual Excursions: a new way to explore science in class

The educational platform Virtual Science Hub (ViSH) has been developed as part of the GLOBAL excursion European project. ViSH (http://vishub.org/) is a portal where teachers and scientist interact to create virtual excursions to science infrastructures. The main motivation behind the project was to connect teachers - and in consequence their students - to scientific institutions and their wide amount of infrastructures and resources they are working with. Thus the idea of a hub was born that would allow the two worlds of scientists and teachers to connect and to innovate science teaching. The core of the ViSH?s concept design is based on virtual excursions, which allow for a number of pedagogical models to be applied. According to our internal definition a virtual excursion is a tour through some digital context by teachers and pupils on a given topic that is attractive and has an educational purpose. Inquiry-based learning, project-based and problem-based learning are the most prominent approaches that a virtual excursion may serve. The domain specific resources and scientific infrastructures currently available on the ViSH are focusing on life sciences, nano-technology, biotechnology, grid and volunteer computing. The virtual excursion approach allows an easy combination of these resources into interdisciplinary teaching scenarios. In addition, social networking features support the users in collaborating and communicating in relation to these excursions and thus create a community of interest for innovative science teaching. The design and development phases were performed following a participatory design approach. An important aspect in this process was to create design partnerships amongst all actors involved, researchers, developers, infrastructure providers, teachers, social scientists, and pedagogical experts early in the project. A joint sense of ownership was created and important changes during the conceptual phase were implemented in the ViSH due to early user feedback. Technology-wise the ViSH is based on the latest web technologies in order to make it cross-platform compatible so that it works on several operative systems such as Windows, Mac or Linux and multi-device accessible, such as desktop, tablet and mobile devices. The platform has been developed in HTML5, the latest standard for web development, assuring that it can run on any modern browser. In addition to social networking features a core element on the ViSH is the virtual excursions editor. It is a web tool that allows teachers and scientists to create rich mash-ups of learning resources provided by the e-Infrastructures (i.e. remote laboratories and live webcams). These rich mash-ups can be presented in either slides or flashcards format. Taking advantage of the web architecture supported, additional powerful components have been integrated like a recommendation engine to provide personalized suggestions about educational content or interesting users and a videoconference tool to enhance real-time collaboration like MashMeTV (http://www.mashme.tv/).

On the cup anemometer working condition monitoring

The analysis of the harmonic terms related to the rotational speed of a cup anemometer is a way to detect anomalies such as wear and tear, rotor non-symmetries (rotor damage) or problems at the output signal system. The research already done in this matter at the IDR/UPM Institute is now taken to cup anemometers working on the field. A 1-2 year testing campaign is being carried out in collaboration with Kintech Engineering. 2 Thies First Class Advanced installed at 58 m and 73 m height in a meteorology tower are constantly monitored. The results will be correlated to the anemometer performance evolution studied through several calibrations planned to be performed along the testing campaign.
