Criterios técnicos del proyecto con módulos tridimensionales ligeros: las casas del Solar Decathlon 2005 y 2007

Este trabajo se ocupa de la construcción modular ligera de viviendas unifamiliares, más concretamente aborda el problema de la definición constructiva de las mismas, habida cuenta de lo poco conocido y publicado de este aspecto en particular. Dado que la construcción es fruto de la evolución, resulta de gran importancia el estudio de los antecedentes para comprender la situación actual, por ello para documentar como corresponde el estado de la técnica y de la investigación se estudiaron los antecedentes desde sus primeras manifestaciones a finales del siglo XIX hasta nuestros días. Contrariamente a las profecías de Le Corbusier y otros, la industrialización no ha llegado a la construcción ni en la forma ni en la medida que era de esperar a principios del siglo XX. Sin embargo y a pesar del relativo “fracaso” de la industrialización en convertirse en la forma mayoritaria de producir edificios, lo cierto es que algunos sistemas altamente industrializados, como lo es la construcción modular ligera, han logrado un lugar en el mercado, que en algunos países resulta cuanto menos significativo. Delimitar el estado de la técnica y la situación actual es crucial en este trabajo, toda vez que la construcción industrializada la realizan empresas, y situarse al margen de las mismas y de su producción, nos guste o no, resulta contrario al sentido común. De este modo se han identificado y documentado ejemplos como el de EE.UU. y Japón, entre otros, que resultan muy ilustrativos tanto desde la evolución como del estado actual. Del estado de la técnica y la investigación también resulta la escasez de publicación de detalles constructivos específicos de la construcción modular ligera. Es obvio que los fabricantes intentan blindarse mediante el secreto industrial, logrando que las soluciones constructivas más interesantes queden fuertemente protegidas dentro del conocimiento reservado de la empresa. De este modo un sistema que alcanza grados de prefabricación del 95%, tan atractivo e interesante para el arquitecto queda reservado al conocimiento de unos pocos dentro de las empresas. La búsqueda de mayor información sobre estos sistemas encuentra un filón indiscutible en los proyectos de las casas del concurso Solar Decathlon. En efecto, debido a las condiciones particulares de este concurso, las casas que compiten deben ser instaladas en un plazo corto, por lo que en su mayoría recurren al método de construcción modular ligera, para lograr correctamente este objetivo. Adicionalmente todos los planos de proyecto incluidos los de detalle, así como memorias de especificaciones técnicas, quedan colgadas en la Web, a libre disposición del público. De este modo se ha considerado interesante, conveniente y útil, aprovechar como fuente documental de este trabajo, aparte de lo obtenido en el estado de la técnica y la investigación, los proyectos de las casas de los concursos 2005 y 2007, que fueron las dos últimas ediciones celebradas cuando se inició esta tesis. De modo similar a esta carencia de detalles publicados se observa igualmente una falta de investigación y de metodologías adecuadas a la misma sobre soluciones y detalles constructivos propios de la construcción modular ligera. Por eso y ante la dificultad de manejar adecuadamente una información disponible pero farragosa, este trabajo ha dedicado una parte importante de su esfuerzo a la creación de una metodología adecuada a este tipo de situación. Hay que destacar que cada proyecto puede constar fácilmente de 60 a casi 200 planos, sin contar las memorias técnicas y otros documentos, tales como galerías de imágenes, etc. Por otra parte resulta útil establecer esta metodología, no solo para esta tesis, sino para futuros trabajos de investigación sobre el tema, toda vez que con posterioridad a 2007 se han celebrado nuevas ediciones del concurso con su correspondiente volumen de información disponible. La metodología del análisis de los proyectos se basa en el diseño y creación de siete fichas tipo que resumen los aspectos fundamentales del proyecto desde el punto de vista constructivo, permitiendo de este modo su rápida visualización y comprensión sin pretender exhaustividad, ya que en caso de querer profundizar en el detalle de la información siempre está el proyecto original para ello. Tras estudiar la información obtenida de los proyectos de las casas de concurso, se contrastan y discuten los resultados para obtener conocimientos de interés para el objetivo propuesto en la tesis. Se comparan los resultados procedentes del estado de la técnica y de la investigación y se obtienen las conclusiones correspondientes. De este modo ha sido posible identificar una serie de criterios técnicos de proyecto de viviendas unifamiliares realizadas mediante construcción modular ligera, que además se organizan en varios niveles, por lo que el resultado es un conjunto de criterios como germen de una futura guía o manual. Como conclusiones fundamentales de la tesis hay que destacar las metodológicas, que habilitan la extensión de este estudio a otros trabajos y la aportación original al conocimiento con la definición de una serie de criterios técnicos de proyecto de viviendas realizadas mediante construcción modular ligera, que además de mejorar esta parte del saber constructivo serán de gran ayuda a los arquitectos de cara a la reducción de errores, que a menudo derivan en mayores costes y plazos, cuando no directamente al abandono del sistema constructivo. El trabajo de la tesis se estructura en siete capítulos a saber: Capítulo 1: Introducción, donde se explica el tema de la tesis, el objetivo principal, las limitaciones y se aportan algunas definiciones. Capítulo 2: Estado de la técnica y la investigación, dentro del cual se presentan los antecedentes desde sus inicios pasando por la primera y segunda mitad del siglo XX y finalizando con el estado actual que recorre los sistemas de EE.UU, Japón, Europa, Escandinavia, centro Europa, Francia, España y algunos ejemplos de Latinoamérica. En el estado de la investigación se presentan las publicaciones tanto en revistas científicas indexadas en el JCR, como publicaciones no indexadas en las que se muestran artículos científicos, comunicaciones a congresos, documentación sobre el concurso Solar Decathlon, libros específicos y libros genéricos sobre construcción modular ligera, tesis doctorales tanto generales como específicas sobre el concurso Solar Decathlon, documentos de idoneidad técnica, páginas Web del concurso Solar Decathlon y finalmente páginas Web de empresas de construcción modular ligera y patentes. También se expresan las conclusiones parciales del capítulo así también como la justificación y los objetivos particulares. Capítulo 3: Metodología, se expone en primer lugar el planteamiento del problema, para luego desarrollar los métodos utilizados para el estudio y clasificación del transporte y de la organización modular, la relación entre la organización modular y distribución espacial, el diseño y contenido de las fichas resumen de los 38 proyectos presentados al SD2005 y SD2007, así también como la información consultada para su realización. Se explica asimismo como se realizaron las tablas comparativas partiendo de la información de las fichas. Finalmente se expresa la manera en que se trató el estudio particular de la junta entre módulos. Capítulo 4: Discusión de resultados, dónde en primer lugar se presenta la clasificación y las estrategias del transporte así también como una clasificación de la organización modular, en segundo lugar se estudian las relaciones que existen entre el sistema modular y la organización espacial. A partir de aquí se muestra el estudio de la estructura de todas las casas del SD2005 y SD2007, según el tipo y material de las zapatas, mostrando tanto tablas cuantitativas como tablas gráficas con fotos. De la misma manera se tratan los forjados, los pilares y las vigas y las cubiertas. Se estudia además el cerramiento opaco y acristalado, la cubierta y el forjado según las capas que lo componen. En el caso de las instalaciones se estudian las que son especiales, descartando las normales en este tipo de casas, como son los paneles fotovoltaicos, placas térmicas o tubos de vacío y los sistemas de almacenamiento de energía, como las baterías, presentando tablas numéricas y gráficas con fotos. El transporte se analiza según corresponda al traslado de la vivienda o al transporte de apoyo, según el tipo y la cantidad utilizado. Con respecto al montaje se diferencia en si se usó grúa o no, y en el caso de no utilizarse se muestran los métodos alternativos. Con respecto a la exploración de la organización modular se presentan la cantidad de módulos que utilizó cada casa, así como también la cuantificación de los sistemas híbridos como son elementos lineales 1D, paneles 2D. Por último se muestra el estudio detallado de la junta entre módulos 3D. Finalmente se realiza la propuesta de un conjunto de criterios técnicos de proyecto organizado en cuatro niveles: 1º nivel de criterios generales, 2º nivel sobre sistemas constructivos, 3º nivel de detalles constructivos y el 4º nivel llamado logística obras previas, transporte y montaje. Capítulo 5: Conclusiones y líneas futuras de investigación, se exponen las conclusiones generales, metodológicas, documentales y por último las de construcción modular. Finalmente se realiza una propuesta de líneas futuras de investigación. Capítulo 6: Bibliografía. Capítulo 7: Anexos, en el que se presentan todas las fichas resumen de las casas realizadas por el autor de esta tesis. Además se incluyen los casos concretos de Voisin en Francia y la TVA (Tennessee Valley Authority) en EE.UU., así como referencias de manuales genéricos de construcción ligera, medidas de transporte en España e información sobre estadísticas de viviendas en la Unión Europea. ABSTRACT This paper deals with Light Modular Construction of houses, and specifically addresses the problem of the constructive definition of the same, given how little known and published this subject has been. Since building construction is the result of evolution, it is of great importance to study its background for understanding the current situation, therefore to document the state of the art and research, its history was studied from its origins dating to the end nineteenth century to our days. Contrary to the prophecies of Le Corbusier and others, industrialization has not reached the construction neither in the form nor to the extent that it was expected in the early twentieth century. However, despite the relative "failure" of industrialization to become the major form of production for buildings, the fact is that some highly industrialized systems, such as the so called Lightweight Modular Construction, have achieved a place in the market, which in some countries is at least significant. To outline the state of the art and the current situation is crucial in this work, since industrialized construction is carried out by companies, and to step away from them and their production, whether we like it or not, it is contrary to common sense. So that, several cases have been identified and documented, such as the US and Japan examples, among others, which are very illustrative both from evolution and the current status. The state of the art and research shows also a shortage of publication of specific construction details of light modular construction. Obviously, manufacturers try to shield themselves by trade secret, making the most interesting constructive solutions remain heavily protected within the reserved knowledge of the company, so a system that reaches levels of 95% prefabrication, so attractive and interesting for the architect It is reserved to the knowledge of a few people inside the companies. The search for more information on these systems finds an invaluable reef in the projects of the Solar Decathlon houses. Indeed, due to the particular conditions of this contest, houses competing must be installed in a short time, so mostly turn to modular construction methods for this purpose to achieve properly this goal. Additionally all levels of project, including detailed and technical specifications reports are published on the Web, freely available to the general public. Thus it was considered interesting, convenient and useful to take advantage as a documentary source of this work, apart from what it were obtained in the state of the art and research, the projects of the houses of the 2005 and 2007 contests, which were the last two editions already held before this thesis was started. Similar to this lack of published details it is also observed a lack of research and methodologies adapted to the solutions and construction details of lightweight modular construction. So that, and facing the difficulty of adequately manage the available but bulky information, this work has devoted a significant part of its effort to create an appropriate methodology for this type of situation. It is noteworthy that each project can easily consist of 60 to almost 200 blueprints, not including technical reports and other documents, such as photo galleries, etc. The methodology of the analysis of the projects is based on the design and creation of seven record sheets that summarize key aspects of the project from a construction point of view, thus allowing quick watching and understanding of the project, without claiming completeness, always keeping for further information the blueprints themselves. After studying the information obtained from the projects of the competition houses, the results are compared and discussed to obtain relevant knowledge according to the objective proposed in the thesis. The results from the state of the art and research are also compared and the conclusions so obtained make possible to identify a number of technical design criteria for single family homes made using lightweight modular construction, which also have been organized at various levels, so the result is a set of criteria as a seed for a future guide or manual. Among the main conclusions of the thesis must be noted the methodological ones, that enable the extension of this study to other works and are an original contribution to knowledge with the definition of a number of technical criteria for housing projects made by light modular construction, what in addition to improving this part of the constructive knowledge will be of great help for the architects to reduce errors that often result in higher costs and delays, if not in abandonment of the construction system itself. The work of the thesis is divided into seven chapters as follows: Chapter 1: Introduction, where the topic of the thesis, the main objective, limitations and the provided definitions is explained. Chapter 2: State of the art and research, within which history is presented from the beginning through the first and second half of the twentieth century and ending with the current systems, that spans from the USA to Japan, Europe, Scandinavia, Central Europe, France, Spain and some Latin American examples. In the state of research publications are presented both on scientific journals indexed in the JCR, and non-indexed publications in which scientific articles, conference papers, information about the Solar Decathlon competition, generic and specific books on light modular construction, articles both general and specific on the Solar Decathlon competition, technical approval documents, dissertations, the Solar Decathlon Web pages and finally lightweight modular construction companies Web pages and patents. The partial conclusions of the chapter as well as the rationale and specific objectives are also expressed. Chapter 3: Methodology first of all exposes the problem statement and then develops the methods used for the study and classification of transportation and modular organization, the relationship between the modular organization and spatial distribution, design and content summary records of the 38 projects submitted to the SD2005 and SD2007, as well as information consulted for its realization. It explains equally how the comparative tables based on information from the chips were made. Finally, the way the particular study of the joint between modules is carried out is also treated. Chapter 4: Discussion, first sorting a classification of transport strategies as well as of modular organization, secondly the relationship between the modular system and the spatial organization studied is presented. From then on, the study of the structure of every house Moreover, to establish this methodology is useful not only for this thesis, but for future research on the subject, since after 2007 there have been held new editions of the contest with a corresponding volume of information available. shown in the SD2005 and SD2007 contests, depending on the type and material of the shoe, showing both quantitative tables as graphic boards with pictures is carried out. Similarly slabs, columns and beams and roofs are treated. Furthermore, the opaque and transparent façades, as well as roof and floor enclosure, according to the layers that compose them are studied. In the case of facilities there have been only addressed that which are of a special type, discarding that considered usual in this type of houses such as photovoltaic panels, thermal panels or vacuum tubes and energy storage systems such as batteries, presenting numerical and graphical tables with photos .The transportation is analyzed depending on it is used to move the house or for additional support, depending on the type and quantity of items used. Regarding assembly it has been made a difference if crane is or not used and if not, what the alternative methods are. With respect to the exploration of the modular organization, the amount of modules used in each house is presented, as well as the quantification of hybrid systems such as linear members as well as 1D, 2D panels. Finally, it has been carried out the detailed study of the joint between 3D modules. Finally it is proposed a set of technical criteria organized into four levels, 1st level of general criteria, 2nd level on building systems, 3rd level construction details and 4th level called previous works and logistics, transportation and assembly. Chapter 5: Conclusions and future research, where general, methodological, documentary and finally modular construction findings are presented. A proposal for further research is done. Chapter 6: Bibliography. Chapter 7: Annexes, in which all the record sheets of houses made by the author of this thesis are presented. Besides the specific cases of Voisin in France and TVA (Tennessee Valley Authority) in the USA, as well as general reference manuals on lightweight construction, transportation dimensions in Spain, and information on housing statistics in the European Union are included.

Modelo tridimensional em elementos finitos para a análise de cabo umbilical STU submetido ao carregamento de crushing.

Este trabalho desenvolve e apresenta um modelo tridimensional em elementos finitos de um cabo umbilical do tipo STU (Steel Tube Umbilical) utilizado na extração offshore de petróleo. Tal modelo é utilizado para estudar o carregamento de crushing, que é imposto ao cabo umbilical pelas sapatas do tensionador durante o seu lançamento, de modo a obter de forma detalhada a distribuição de tensões nos componentes do núcleo, com foco nos tubos de aço utilizados para o transporte de fluidos. A metodologia empregada no desenvolvimento do modelo é descrita detalhadamente ao longo do trabalho, de forma que possa vir a ser utilizada no estudo de outras configurações de cabos umbilicais. O modelo elaborado é utilizado (i) como paradigma para a validação de um modelo bidimensional, que visa analisar o mesmo problema de forma mais simples e rápida, e (ii) para o estudo do comportamento das tensões nos tubos de aço na região de transição de entrada/saída da sapata. Na comparação entre os modelos bi e tridimensional, o trabalho conclui pela validade do modelo bidimensional na avaliação das tensões nos tubos de aço resultantes do carregamento de crushing, na região central do cabo. O estudo realizado na região de transição de entrada/saída da sapata permitiu verificar que ocorre um aumento dos níveis de tensão nos tubos de aço nessas regiões de transição, com redistribuição do campo de tensões após plastificação.

Double Reasonableness and the Fourth Amendment

Recently the Supreme Court has placed new limits on both the substance of the Fourth Amendment and the exclusionary that serves as the principal remedy for Fourth Amendment violations. In this Article we briefly summarize these limitations and then argue that the curtailment of the exclusionary rule has the potential to ameliorate substantive Fourth Amendment doctrine. The limited reach of the modern exclusionary rule provides the Court with license to develop an expansive new substantive framework free of the specter of a correspondingly expansive remedial framework. One point on which nearly all jurists and commentators agree is that current Fourth Amendment doctrine is a mess. We argue that the Court’s exclusionary rule cases, while frustrating and ill-conceived if viewed in isolation, provide the Court with an opportunity to revisit problematic Fourth Amendment doctrine that was born under a very different remedial regime. Such an approach would allow the Court to adhere to its current view of the exclusionary rule as a remedy of last resort while creating a Fourth Amendment with teeth. The goal is a Fourth Amendment right that is more substantial and clearly defined, but a remedy that remains limited to egregious violations of clear substantive rules. The time is now to lift the Fourth Amendment fog.

The Jewish Law Firm: Past and Present

The rise and growth of large Jewish law firms in New York City during the second half of the twentieth century was nothing short of an astounding success story. As late as 1950, there was not a single large Jewish law firm in town. By the mid-1960s, six of the largest twenty law firms were Jewish, and by 1980, four of the largest ten prestigious law firms were Jewish firms. Moreover, the accomplishment of the Jewish firms is especially striking because, while the traditional large White Anglo-Saxon Protestant law firms grew at a fast rate during this period, the Jewish firms grew twice as fast, and they did so in spite of experiencing explicit discrimination. What happened? This book chapter is a revised, updated study of the rise and growth of large New York City Jewish law firms. It is based on the public record, with respect to both the law firms themselves and trends in the legal profession generally, and on over twenty in-depth interviews with lawyers who either founded and practiced at these successful Jewish firms, attempted and failed to establish such firms, or were in a position to join these firms but decided instead to join WASP firms. According to the informants interviewed in this chapter, while Jewish law firms benefited from general decline in anti-Semitism and increased demand for corporate legal services, a unique combination of factors explains the incredible rise of the Jewish firms. First, white-shoe ethos caused large WASP firms to stay out of undignified practice areas and effectively created pockets of Jewish practice areas, where the Jewish firms encountered little competition for their services. Second, hiring and promotion discriminatory practices by the large WASP firms helped create a large pool of talented Jewish lawyers from which the Jewish firms could easily recruit. Finally, the Jewish firms benefited from a flip side of bias phenomenon, that is, they benefited from the positive consequences of stereotyping. Paradoxically, the very success of the Jewish firms is reflected in their demise by the early twenty-first century: because systematic large law firm ethno-religious discrimination against Jewish lawyers has become a thing of the past, the very reason for the existence of Jewish law firms has been nullified. As other minority groups, however, continue to struggle for equality within the senior ranks of Big Law, can the experience of the Jewish firms serve as a “separate-but-equal” blueprint for overcoming contemporary forms of discrimination for women, racial, and other minority attorneys? Perhaps not. As this chapter establishes, the success of large Jewish law firms was the result of unique conditions and circumstances between 1945 and 1980, which are unlikely to be replicated. For example, large law firms have become hyper-competitive and are not likely to allow any newcomers the benefit of protected pockets of practice. While smaller “separate-but-equal” specialized firms, for instance, ones exclusively hiring lawyer-mothers occasionally appear, the rise of large “separate-but-equal” firms is improbable.

Efficient tool path computation using multi-core GPUs

Tool path generation is one of the most complex problems in Computer Aided Manufacturing. Although some efficient strategies have been developed, most of them are only useful for standard machining. However, the algorithms used for tool path computation demand a higher computation performance, which makes the implementation on many existing systems very slow or even impractical. Hardware acceleration is an incremental solution that can be cleanly added to these systems while keeping everything else intact. It is completely transparent to the user. The cost is much lower and the development time is much shorter than replacing the computers by faster ones. This paper presents an optimisation that uses a specific graphic hardware approach using the power of multi-core Graphic Processing Units (GPUs) in order to improve the tool path computation. This improvement is applied on a highly accurate and robust tool path generation algorithm. The paper presents, as a case of study, a fully implemented algorithm used for turning lathe machining of shoe lasts. A comparative study will show the gain achieved in terms of total computing time. The execution time is almost two orders of magnitude faster than modern PCs.

Augmented and Virtual Reality techniques for footwear

The use of 3D imaging techniques has been early adopted in the footwear industry. In particular, 3D imaging could be used to aid commerce and improve the quality and sales of shoes. Footwear customization is an added value aimed not only to improve product quality, but also consumer comfort. Moreover, customisation implies a new business model that avoids the competition of mass production coming from new manufacturers settled mainly in Asian countries. However, footwear customisation implies a significant effort at different levels. In manufacturing, rapid and virtual prototyping is required; indeed the prototype is intended to become the final product. The whole design procedure must be validated using exclusively virtual techniques to ensure the feasibility of this process, since physical prototypes should be avoided. With regard to commerce, it would be desirable for the consumer to choose any model of shoes from a large 3D database and be able to try them on looking at a magic mirror. This would probably reduce costs and increase sales, since shops would not require storing every shoe model and the process of trying several models on would be easier and faster for the consumer. In this paper, new advances in 3D techniques coming from experience in cinema, TV and games are successfully applied to footwear. Firstly, the characteristics of a high-quality stereoscopic vision system for footwear are presented. Secondly, a system for the interaction with virtual footwear models based on 3D gloves is detailed. Finally, an augmented reality system (magic mirror) is presented, which is implemented with low-cost computational elements that allow a hypothetical customer to check in real time the goodness of a given virtual footwear model from an aesthetical point of view.

Footwear bio-modelling: An industrial approach

There is a growing need within the footwear sector to customise the design of the last from which a specific footwear style is to be produced. This customisation is necessary for user comfort and health reasons, as the user needs to wear a suitable shoe. For this purpose, a relationship must be established between the user foot and the last with which the style will be made; up until now, no model has existed that integrates both elements. On the one hand, traditional customised footwear manufacturing techniques are based on purely artisanal procedures which make the process arduous and complex; on the other hand, geometric models proposed by different authors present the impossibility of implementing them in an industrial environment with limited resources for the acquisition of morphometric and structural data for the foot, apart from the fact that they do not prove to be sufficiently accurate given the non-similarity of the foot and last. In this paper, two interrelated geometric models are defined, the first, a bio-deformable foot model and the second, a deformable last model. The experiments completed show the goodness of the model, with it obtaining satisfactory results in terms of comfort, efficiency and precision, which make it viable for use in the sector.

Selected characteristics of gait in women of different ages

In our research we have attempted to find out and compare force and time characteristics of gait in women. We measured and compare women in two age groups - 18-30 (group 1) a 46-60 (group 2). The average height of both groups was same, 167 cm, while the average weight and average body mass index were different (group 1 - weight 62 kg, BMI 22,3, group 2 - weight 68 kg, BMI 24,6). For measuring, pressure shoe insoles were used (Pedar Mobile, Novel Munich, 99 sensors, 100 Hz). Each person had three attempts: two trial attempts, the third one was measured. For observation, we selected three stances of each leg, always between the third and eighth stride. We measured force characteristics F1, F2, F3 and time characteristics t, t1, t2, t3. Significant differences between both groups were found in t3 on the left leg (time between peak force in active part of stance and peak force in passive part of stance). With applied force (F1, F2, F3) during stance, after recalculating per a kilogram of weight, no statistically significant differences were found.

Levantando las arquitecturas de las guerras en la costa del Mediterráneo (1936-1939)

During the civil war (1936-39) was built a network of defensive settlements on the coast in anticipation of attacks enemies, forming the so-called 'wall Mediterranean', because of its similarity with the Wall Atlantic of the World War II. These enclaves were composed of groups of batteries, bunkers and buildings. This communication comes to inventory and draw the remains of more than 50 architectures that are located in the Valencian South Coast (from Denia to Torrevieja), documenting the first ruins of hormigion armed with our history. It's a set of military settlements anti-aircraft, mostly scattered coastal rural, which are a great heritage and landscape value, and from which planes haven't been preserved. It is to lift current state record of them all, proceeding to its typological classification, in order to contribute to its assessment and protection on the grounds that they constitute a legacy of architectural heritage that increases our cultural memory.history.

Em busca da originalidade do patrimônio cultural na cidade-espetáculo: o caso da Casa Boehm em Joinville/SC

Este trabalho tem o intuito de discutir como um imóvel tombado na cidade de Joinville/SC vem respondendo ao mundo das influências contemporâneas da espetacularização. A Casa Boehm, hoje uma loja de calçados no comércio, foi construída em 1927 e tombada em 2001, por meio do Processo de Tombamento PFCC n. 627/003, de 10 de abril de 2000, homologado pelo Decreto n. 3.461/2001, do Governador do Estado, na época, Esperidião Amin. O imóvel vem sofrendo alterações físicas, que afetam princípios de unidade, volumetria, padrões de estilo arquitetônico, o que faz com surjam debates a respeito dos seus valores estéticos. A depender do gosto dos locatários, especialmente no que se referee às cores externas, sem autorização, vislumbra-se a partir da opinião dos participantes do Conselho de Patrimônio da cidade - COMPHAAN, a espetacularização que este bem vem suportando em nome de uma sociedade de consumo, que apenas visa o lucro, apesar de inúmeros debates teóricos acerca da preservação. Desta forma, quando se pensa em restauração de um patrimônio cultural edificado, a preocupação imanente é com a sua imagem subjetiva/simbólica, e ainda, não menos importante, no que se refere às cores utilizadas nas pinturas das edificações. A metodologia utilizada é qualitativa, por meio de pesquisa bibliográfica, documentais no Arquivo Histórico de Joinville – AHJ e na Fundação Cultural de Joinville – FCJ e, etnográfica. A etnografia, com nuances interdisciplinares, foi realizada nestes mesmos Arquivos da cidade de Joinville, nos arredores do bem em questão e analisando algumas impressões obtidas nas reuniões do Conselho de Patrimônio da cidade – COMPHAAN. Este estudo é parte integrante da pesquisa para doutoramento em Ciências Humanas, na Universidade Federal de Santa Catarina – UFSC. Parte-se da hipótese inicial de que as discussões que envolvem as cores em bens tombados têm se relacionado com a autenticidade e a integridade dos conjuntos nos centros históricos. Porém, vai além, já que o espetáculo buscado pelos gestores públicos, com intento de valorizar suas cidades, acaba por homogeneizar esses territórios em torno de uma ideia de patrimônio que tem sido questionada por alguns teóricos.

Records of cases before the Mayor's Court of Albany, 1786-1796

Contains a summary of cases before the court beginning with the litigants and the damages sought, the legal action, names of counsel, actions taken, and the final disposition of the case. Most actions taken relate to debt, assault and battery, and slander and libel. At the back of the manuscript are "an account of law books by me purchased in the year 1784 & 1785" [p. 120], and"a list miscellanious books bought in the year 1784 & 1785" [p. 132].

Account book of Andrew Croswell, 1794-1802

Andrew Croswell kept this account book while an undergraduate at Harvard College. It contains entries from 1794, the year he entered, until his graduation in 1798. There is also one entry on the back cover apparently made in 1802. The entries, divided by school term, are very detailed. Croswell indicates the cost of the following, among many other expenses and purchases: transportation, most often to Hingham and Plymouth; payment for "passing the bridge"; candles; hiring a horse; wood and having it cut; laundry; quills and pencils; paper and ink; razors, haircuts, hair ribbons; a trunk; clothing and cloth for trousers; furniture; tickets to the theater; door locks; a bowl and spoon; "batts and balls" and "other necessaries"; tobacco; toothbrushes; shoe and boot repair; fruit; wine, brandy and rum; cheese; coffee and tea; butter; lemons; sugar; and wafers. There are also entries for college-related costs, including the payment of quarter bills, buttery bills, Hasty Pudding Club dues, and a fee to the President of Harvard College related to Croswell's graduation. There are also entries pertaining to the cost of celebrating various special occasions, including Election Day, Christmas Eve, "Independent Day," and George Washington's birthday.

Wind Shear, Gust, and Yaw-Induced Dynamic Stall on Wind-Turbine Blades

This study examined the effect of a spanwise angle of attack gradient on the growth and stability of a dynamic stall vortex in a rotating system. It was found that a spanwise angle of attack gradient induces a corresponding spanwise vorticity gradient, which, in combination with spanwise flow, results in a redistribution of circulation along the blade. Specifically, when modelling the angle of attack gradient experienced by a wind turbine at the 30% span position during a gust event, the spanwise vorticity gradient was aligned such that circulation was transported from areas of high circulation to areas of low circulation, increasing the local dynamic stall vortex growth rate, which corresponds to an increase in the lift coefficient, and a decrease in the local vortex stability at this point. Reversing the relative alignment of the spanwise vorticity gradient and spanwise flow results in circulation transport from areas of low circulation generation to areas of high circulation generation, acting to reduce local circulation and stabilise the vortex. This circulation redistribution behaviour describes a mechanism by which the fluctuating loads on a wind turbine are magnified, which is detrimental to turbine lifetime and performance. Therefore, an understanding of this phenomenon has the potential to facilitate optimised wind turbine design.

Desenvolvimento económico baseado na teoria dos Clusters: o exemplo do calçado em Portugal

Este trabalho aborda o tema dos clusters industriais - concentrações geográficas de empresas interligadas, fornecedores de produtos e serviços, empresas em setores afins e entidades que lhes estão associadas, como as universidades, entidades públicas, associações empresariais. A competitividade resulta da ação das empresas, e estas devem competir e cooperar para criar lucro económico, mas também gerar benefícios para a região e o país. O objetivo deste trabalho é demonstrar que a aplicação da teoria dos clusters no nosso país, - introduzida na sequência de um estudo pedido em 1994 ao criador desta teoria, o Dr. Michael Porter – teve efeitos muito positivos no desenvolvimento dos últimos 20 anos e que maiores poderiam ter sido esses efeitos, se tivesse sido feita a sua aplicação em todos os setores em que se identificavam vantagens competitivas da nossa economia. Foi realizada uma análise da evolução do mais reconhecido cluster, o da indústria do calçado, cujos resultados apontam para as estratégias a adotar em muitos outros setores da nossa economia. Numa extrapolação, fica claro que as regiões nacionais e os países que contam com clusters industriais são aqueles que apresentam desempenho superior, em termos de intensidade exportadora e valor acrescentado. Estas zonas apresentam ainda níveis elevados de riqueza e longevidade dos seus cidadãos. Em termos europeus, a Alemanha, que tem como grandes clusters os setores automóvel, da automação, da eletrónica e da pesquisa laboratorial, é o melhor exemplo deste facto.

Making the impossible possible: the prospects for visa-free movement between the EU and its eastern partners. OSW Point of View Number 27, May 2012

To make the abolition of visas in relations between the EU and the Eastern European countries possible, the ”spell cast” must be broken on this issue. With the present levels of mobility and people-to-people, business and political contacts the introduction of a visa-free regime will be a natural consequence of the liberalisation processes which have been at work for years.Moreover, the decision to lift the visa requirement is unlikely to significantly stimulate an increase in migration pressure from Eastern European countries but could reduce the operating costs of expanded Schengen consular network. Lifting the visa requirement for Eastern European citizens can be temporary and conditional and allow for actual implementation of an increased conditionality rule. In political terms, making visa liberalisation a key issue would fundamentally change the partners’ approach to the Eastern Partnership and would provide a link to the Partnership for Modernisation targeted at Russia.
