Edificio de equipamiento dotacional para deportes de arena en Vitoria-Gasteiz

Castellano En la península ibérica y en el resto de Europa está creciendo el índice de personas que practican modalidades deportivas que se desarrollan en ambientes costeros y en buenas condiciones climáticas. Las limitaciones que supone el clima y la necesidad de playa, impiden la realización de estas actividades al no contar con instalaciones idóneas para estos deportes, disminuyéndose así la oferta y promoción de estos. Actualmente, existen pabellones deportivos preparados para asegurar confort a los usuarios en zonas donde el ambiente es desfavorable. No obstante, en España, y sobre todo en la zona Norte, carecen de ese tipo de instalaciones impidiendo el desarrollo de entrenamientos y competiciones en temporada de invierno. Por ello, se plantea la implantación de un edificio que subsane dichas carencias en el ámbito deportivo del interior del País Vasco, más en concreto en la ciudad de Vitoria-Gasteiz, donde predominan las bajas temperaturas y precipitaciones de larga duración a lo largo del año. En los documentos que se presentan, se trata de estudiar la viabilidad del proyecto y ofrecer una solución a un edificio con las características necesarias para satisfacer con este cometido, la práctica de deportes de arena en Vitoria-Gasteiz

The history of the Cité Balzac and the vicious circle of social housing

The history of the Cité Balzac, a housing complex built in the 1960’s in Vitry-sur-Seine, an emblematic “red suburb” in the south of Paris, reveals several transformations on public housing policies in France and some permanencies throughout five decades. Originally built to provide affordable housing for the inhabitants of problematic neighbourhoods within Paris, this large-scale complex inspired by post war architectural models and organized following functionalist urban-ism schemes has been initially occupied by an emerging middle class that left the apartments when private property became encouraged by a liberal government during the 1970’s. The social housing apartments were by then occupied by impoverished immigrants and French citizens coming from former colonies and became stigmatized as a symbol of social problems and ethnic conflicts. Recently, even being situated in a municipality dominated by the French Communist Party since 1920’s, the Cité Balzac was the epicentre of an intense urban renovation project led by the National Agency for Urban Renewal (ANRU), giving room to a controlled gentrification process that tried to erase the image of sensible neighbourhood that characterized this territory and its surroundings with the demolition of the bigger blocks and the ‘residentialization’ of the smaller ones. This project opened space for new housing blocks built by real estate and public works contractors based on private property to be occupied by middle class families that couldn’t afford to buy in Paris intramuros. This controlled gentrification happened gradually as the Grand Paris project was taking place, expanding the limits of the French capital to its closer suburbs with the extension and improvement of the public transportation system, feeding a vicious circle that raises fundamental issues about the role of social housing and its contradictions

Synthesis of Metal Boranes as Solid-State Electrolytes for Next Generation Battery Applications

Modifying conventional batteries by replacing liquid electrolytes with solid ionic conductors is a novel strategy for developing next-generation energy storage devices (solid-state batteries) with increased safety, energy density, and reduced costs. Metal-boranes have shown promising features as solid-state electrolytes, due to their high ionic conductivity and compatibility with alkali-metal anodes. The synthesised metal-boranes demonstrate promising properties for further research and application as solid-state electrolytes in batteries

Inverse problems for linear parabolic equations using mixed formulations -Part 1 : Theoretical analysis

We introduce in this document a direct method allowing to solve numerically inverse type problems for linear parabolic equations. We consider the reconstruction of the full solution of the parabolic equation posed in Ω × (0, T)-Ω a bounded subset of R N-from a partial distributed observation. We employ a least-squares technique and minimize the L 2-norm of the distance from the observation to any solution. Taking the parabolic equation as the main constraint of the problem, the optimality conditions are reduced to a mixed formulation involving both the state to reconstruct and a Lagrange multiplier. The well-posedness of this mixed formulation-in particular the inf-sup property-is a consequence of classical energy estimates. We then reproduce the arguments to a linear first order system, involving the normal flux, equivalent to the linear parabolic equation. The method, valid in any dimension spatial dimension N , may also be employed to reconstruct solution for boundary observations. With respect to the hyperbolic situation considered in [10] by the first author, the parabolic situation requires-due to regularization properties-the introduction of appropriate weights function so as to make the problem numerically stable

A mixed formulation for the direct approximation of L2-weighted controls for the linear heat equation

This paper deals with the numerical computation of null controls for the linear heat equation. The goal is to compute approximations of controls that drive the solution from a prescribed initial state to zero at a given positive time. In [Fernandez-Cara & Münch, Strong convergence approximations of null controls for the 1D heat equation, 2013], a so-called primal method is described leading to a strongly convergent approximation of distributed control: the controls minimize quadratic weighted functionals involving both the control and the state and are obtained by solving the corresponding optimality conditions. In this work, we adapt the method to approximate the control of minimal square integrable-weighted norm. The optimality conditions of the problem are reformulated as a mixed formulation involving both the state and its adjoint. We prove the well-posedeness of the mixed formulation (in particular the inf-sup condition) then discuss several numerical experiments. The approach covers both the boundary and the inner situation and is valid in any dimension.Coordenação de aperfeiçoamento de pessoal de nivel superiorMinisterio de Ciencia e Innovació

Infrastructure, canning and architecture: the case of Matosinhos

In this article, we seek to reconnect architectural history with social and industrial histories as a strategy for understanding the relationship between infrastructure, fishing, and urbanisation by studying the emblematic case of Matosinhos. This paper traces the formation of the port area and the process of its subsequent transformation with the development of the fishing and canning industries, to understand the relationship between urban planning, the architectures of production (infrastructures, industries, and urbanism) and the architectures of reproduction (housing), and the dynamics of the physical and economic transformations, as well as the key role played by the port in supporting the urbanisation process. In the last decades of the twentieth century, the canneries almost completely disappeared and the gap left by its concentration and modernisation led to the creation of a new urbanisation plan, directed by Álvaro Siza Vieira. Recent works, such as the seaside platform designed by Eduardo Souto de Moura and built at the beginning of the present century, the redevelopment of Leça’s shoreline in 2006 or the conversion of the ruins of a former winery into the new ‘house of architecture,’ are signs of growing functional disputes and symbolic transformations of a particular port cityThe Sea and the Shore, Architecture and Marine Biology: The Impact of Sea Life on the Built Environment PTDC/ART-DAQ/29537/201

Conversor de alta tensão e alta frequência para carga resistiva com variação imprevisível

Orientador: José Antenor PomilioDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Engenharia Elétrica e de ComputaçãoResumo: Transformadores de alta tensão possuem algumas características específicas, uma vez que o efeito de elementos parasitas é amplificado, devido ao elevado número espiras, necessário para se atingir os níveis de tensão desejados. A operação em alta frequência reduz o volume de dispositivos magnéticos, tornando os sistemas mais compactos, o que pode, no entanto, dar margem a outros problemas, como ruídos de alta frequência, interferência eletromagnética e manifestação de ressonâncias. Nesta dissertação foi desenvolvido um conversor de alta tensão, com operação em alta frequência para transferência de potência para uma carga resistiva com variação imprevisível, desde uma situação de curto-circuito até a de circuito aberto, levando em consideração as particularidades do transformador de alta tensão operando em alta frequência. Simulações e cálculos teóricos foram realizados para caracterização do comportamento do sistema. Sistemas de proteção, controle e supervisão foram desenvolvidos para minimizar os efeitos de elementos parasitas e ressonâncias, bem como para garantir a operação segura do conversor. Um protótipo conceitual foi construído para validação das simulações e cálculos realizadosAbstract: High voltage transformers have specific characteristics, since the effect of some parasitic elements is highlighted, due to its high number of turns, in order to reach the desired voltage levels. High frequency operation reduces the volume of magnetic devices, making the systems more versatile, however it can give rise to other problems such as switching noise, electromagnetic interference and resonances. In this dissertation a high voltage converter, with high frequency operation was developed for power transferring to resistive loads with unpredictable variation, from the short circuit to the open circuit condition, taking in account the High Voltage High Frequency Transformer¿s particularities. Simulations and theoretical calculations were made to characterize the system¿s behavior. Protection, control and supervision systems were developed to minimize the effects of parasitic elements and resonances, as well as to ensure the safe and correct converter¿s operation. A conceptual prototype was built to validate the simulations and calculations performedMestradoEnergia EletricaMestre em Engenharia Elétric

The motion of a ball moving down a circular path

The problem of a body slipping down a frictionless hemisphere is very common in physics and engineering textbooks. In this type of problem, students are normally asked to find the angle at which the body flies off the surface. In this work, we have constructed an apparatus to determine the angle at which a ball flies off a circular track, and to study the motion of the ball (rolling and slipping) along the surface. The apparatus is comprised of two parallel rails that form a quarter circle. The angular position and velocity of a steel ball are measured using a moveable arm equipped with a photodetector. Two methods are used to determine the angle the ball loses contact with the track. Both methods provide values in agreement with a model for rolling followed by slipping.

The political uses of theater. Scientific and medical sociability in the city of Buenos Aires at the end of the century (1870 -1920)

Se estudian tres ceremonias científicas organizadas en distintos teatros de la ciudad de Buenos Aires por el Círculo Médico Argentino (CMA). Como parte de las prácticas de sociabilidad de esta institución, estas ceremonias, dedicadas a conmemorar episodios e individuos centrales en la frágil comunidad médica de la segunda mitad del siglo XIX, fueron uno de los recursos utilizados por el CMA para la transmisión de sentidos, valores y representaciones acerca de la práctica médica local a la sociedad civil y el poder político de su época. Esta estrategia de amplificación de los aspectos simbólicos y culturales de la práctica profesional y científica de la medicina fue utilizada por el CMA tanto para construir audiencias mayores, ganar visibilidad y demandar legitimidad para el conjunto de prácticas médicas, como para abrir una brecha de acceso al reconocimiento político en una ciudad con tendencia a mirar como extraños a médicos y hospitales hasta bien entrado el siglo XX. En especial, los tres casos estudiados permiten ilustrar las estrechas relaciones entre las ceremonias teatrales y la puesta en circulación de un programa experimental para las ciencias médicas de la ciudad de Buenos Aires.Three scientific ceremonies organized in different theaters of the city of Buenos Aires by the Argentine Medical Circle (CMA) are studied. As part of practices of sociability of this institution, these ceremonies dedicated to commemorate episodes and central individuals in the medical community in the second half of the nineteenth century were one of the resources used by the CMA for the transmission of meanings, values and representations about the local medical practice civil society and political power. This amplification strategy of symbolic and cultural aspects of professional and scientific practice of medicine was used by the CMA both to build larger audiences, gain visibility and claim legitimacy for all medical practices, such as to open a gap in access to political recognition in a city with a tendency to look like strangers to doctors and hospitals until well into the twentieth century. In particular, the three case studies to illustrate the close relationship between the theatrical ceremonies and the circulation of a pilot program for medical sciences in Buenos Aires city.Fil: Souza, Pablo Andres.
