In its short history, fabric structures have fascinated architects and engineers alike. Architects appreciate their unusual shapes and forms while engineers delight in their "pure" structural expression. Capable of spanning large distances while incurring very little weight on supporting structure, developments in the design of fabric structure can dramatically change the ways in which permanent building construction is conceptualized. This thesis reviews the most current methods for design and construction of fabric structures and focuses on how they can be improved for common application as permanent structures. In doing so, it begins with a brief history and explanation of the various types of fabric structure that have previously been built. Subsequent chapters address different limiting factors, including the development of fabric materials, computational analysis methods, and innovative construction techniques. Finally, a case study of the new Landside Airport Terminal project in Denver, Colorado is presented to illustrate a direct application of design and construction methods. Though fabric structures have come a long way since the first modern cable-net was built fifty years ago, there are still several challenges to be overcome before fabric can be considered a viable option for the majority of new building projects.

Abstract:

Continuing advances with VLSI have enabled engineers to build high performance computer systems to solve complex problems. The real-world problems and tasks like pattern recognition, speech recognition, etc. still remain elusive to the most advanced computer systems today. Many advances in the science of computer design and technology are coming together to enable the creation of the next-generation computing machines to solve real-world problems, which the human brain does with ease. One such engineering advance is the field of neuromorphic engineering, which tries to establish closer links to biology and help us investigate the problem of designing better computing machines. A chip built with the principles of neuromorphic engineering is called as neuromorphic chip. Neuromorphic chip aims to solve real-world problems. As the complexity of the problem increases, the computation capability of these chips can become a limitation. In order to improve the performance and accomplish a complex task in the real-world, many such chips need to be integrated into a system. Hence, efficiency of such a system depends on effective inter-chip communication. Here, the work presented aims at building a message-passing network (Digital Fabric) simulator, that integrates many such chips. Each chip represents a binary event-based unit called spiking analog cortical module. The inter-chip communication protocol employed here is called as Address Event Representation. Here, the Digital Fabric is built in three revisions, with different architectures being considered in each revision. The complexity is increased at each iteration stage. The experiments performed in each revision test the performance of such configuration systems and results proves to lay a foundation for further studies. In the future, building a high level simulation model will assist in scaling and evaluating various network topologies.

Abstract:

Within this Book is a glimpse of the world that was brought forth from my thesis work. When beginning to find the place of the thesis work, I assumed that I should be making an architectural construction at the scale of building, the scale in which I then believed architecture existed. Knowing that I wanted to find a way of making where I could physically construct every thing I was to make in a careful architectural manner, I hoped that this consideration would lend itself to the design of a building (the kind that people can physically inhabit). What I found was that the building I am making is of a different sort of inhabiting, and that I have been able, through making, to hone my tools. With these I can come to a site(situation), and begin to make decisions that are in the world of architecture. The textile article, one made of woven fibre, is continually referenced throughout this thesis. Being assured of the very close connection between fabric and building (Oxford English Dictionary definition), A Building as being a Fabric, I have explored the literal physical kinds of connections to which fabric lends itself. Fabric items (those made with fibre) engage the world of the temporary connection (a button, a tied closure), because of this, the exploration of temporary construction was naturally a part of this thesis. Finding that though physically temporary, the connection between a site and its construction, can have a presence that has more permanence in its temporal quality than if it were to have a more physical permanence. During the making of each thing, it became clear to me that the woven must have limits; there is a beginning and a completion (Looms have a frame for construction with particular dimensional limits). What is that beginning and completion in each of the thesis projects, what is the construction? In order to have a metaphorical and physical understanding for myself it has been necessary to bring back that question into the realm of the textile and fabric article. What do you do with fabric? It is sewn into particular constructions. This particularity has the beginnings and completions to transform fabric into made things. The woven stuff can go on forever but it takes decision and an idea to take the material into a physical realization. It occurred to me that when one uses material in any form to create a construction, there are particular decisions made that have to stop the woven thing and bind it so that it can be made into something in particular. It seems that within the world of architecture it is important to know when to stop an action and when to make a decision, not letting something default into indistinguishablity.

Abstract:

This work deals with definition of garments. It explores how little changes a piece of fabric needs to still make it into a garment. What is it that defines a garment, is it just that something is done with a piece of fabric or does it need some recognizing of body parts. The aim is to find new ways of construction without using templates and questioning when textile becomes garments by draping and cutting.Through using how clothes are fitted to the body but instead of using pattern templates work from a rectangle and make it fit the body as garment. Working from two-dimensional to three-dimensional by the help of the body, going directly from fabric to garment. By defining the essential parts in every garment and cutting holes in a rectangle to highlight a certain body part or letting the body go trough different holes to make the fabric turn and drape around the body. Conclusion of the work is that a cut or incision doesn’t always define a garment, that it takes another recognition as well to make the definition. During the development questions have arise as for example how to construct holes in all fabrics and deal with the finishing, how to use raw edges without ripping, how to sew were there is no seam allowance and how to create fabric suited for cutting.

Abstract:

Reconfigurable computing architectures combine the flexibility of software with the performance of custom hardware. Such architectures are of particular interest at the nanoscale level. We argue that a bottom-up self-assembled fabric of nodes will be easier and cheaper to manufacture, however, one has to make compromises with regards to the device regularity, homogeneity, and reliability. The goal of this thesis is to evaluate the performance and cost of a self-configurable computing architecture composed of simple reconfigurable nodes for unstructured and unknown fabrics. We built a software and hardware framework for this purpose. The framework enables creating an irregular network of compute nodes where each node can be configured as a simple 2-input, 4-bit logic gate. The compute nodes are organized hierarchically by sending a packet through a top anchor node that recruits compute nodes with a chemically-inspired algorithm. The nodes are then self-configured by means of a gate-level netlist describing any digital logic circuit. A topology-agnostic optimization algorithm inspired by simulated annealing is then initiated to self-optimize the circuit for latency. Latency comparisons between non-optimized, brute-force optimized and our optimization algorithm are made. We further implement the architecture in VHDL and evaluate hardware cost, area, and energy consumption. The simple on-chip topology-agnostic optimization algorithm we propose results in a significant (up to 50\%) performance improvement compared to the non-optimized circuits. Our findings are of particular interest for emerging nano and molecular-scale circuits.

Abstract:

The nature of this research is in advancing conventional structures and their methods of construction by exploring new technology. The formwork construction of the modern concrete structure involves the use of rigid materials such as steel and timber. This type of formwork often produces structures of forms with limited flexibility which would also hinder the even distribution of the induced stresses. To construct concrete structures with more organic forms; ones that responds to a more natural flow of the induced stresses, it is thought to be more logical to use flexible mould such as the fabric formwork. In such form-active shape the materials’ utilization can be maximized and the degree of material waste can be reduced. For example, when the form responds to the externally applied loads in the way that the internally incurred stresses at any point of the body closely match the capacity of the material, then the form is material-efficient and said to be in its optimal form. The use of fabric formwork, due to its permeability can also improve the quality of concrete by eliminating any air holes on the surface, and also there are reports showing the increase in concrete’s compression strength due to the reduction in water-cement ratio when cast in a fabric mould. This research concentrates on finding such material-efficient form (thus more sustainable) for reinforced concrete beam of improved material quality, through the development of the more efficient construction system of flexible fabric formwork. For this research 11 different types of beams have been built and tested in total, and their construction methods are illustrated and discussed also (Chapter 7 and Chapter 4 respectively). The designs of the beams are developed through consecutive experiment, analysis, evaluation, and modification process (Chapter 6). For the structural analysis of the beams, the most widely accepted analysis methods are reviewed and adapted (Chapter 8). Based on the evaluations of the analytical results the following variables of the beams are modified through the development of the beam designs: The effect of Compression Steel Mesh in Flange Stress Distribution Around Anchorage; Vertical and Horizontal Web Geometry Varying Depth of Flange Steel Content Also it is a part of the current research’s aim to look at the possible application of the current design methods for the design of the fabric formed beams that are discussed in this research. Thus the experimental results are compared with the results which are calculated from the standard design methods suggested by the British Standard Code of Practice (BS8110) (Chapter 9). Computational finite element (FE) analysis is carried out where more intensive analysis is required (Chapter 10). The results of the FE analysis are also compared with the theoretical and experimental results for the verification purpose. The material efficiency of the beam in its final form is assessed through the embodied energy analysis, which compares the total embodied energy consumed through the construction of the beam with a virtual beam that is designed in accordance with the BS8110 (Chapter 11). The analysis indicates that the total embodied energy of the fabric formed beam is about 20~40% less in comparison with the beam designed in accordance with the BS8110. This thesis has the purpose to illustrate and provide the practical information on the design and the construction process of the fabric formed beams, which can be used as a reference to the future research and construction.

Full text

Abstract:

This work is a proposal for an alternative approach to working with print, making the printing process a key element within designing. It is an investigation into flat garment construction between fabric layers, as this enables for the printing to be used in place of sewing. Additionally, working with multiple textile layers connects with the reference of the peeling wallpaper, which is used as a base for material and form developments. The aim of the work is to develop a more holistic approach and new expressions in garment-making in relation to the application of printing processes within textile layers. The main objective is to present a new perspective of the relationship between garment pattern and print, bringing the later forward. Not only does the surface print, through the interaction of colour and texture provide an important element in terms of creating expression, but it additionally acts as a construction element. Moreover, by using the process of printing to create form the element of print becomes integrated into the process of garment-making.

Abstract:

Optical packet switching (OPS) is one of the more promising solutions for meeting the diverse needs of broadband networking applications of the future. By virtue of its small data traffic granularity as well as its nanoseconds switching speed, OPS can be used to provide connection-oriented or connectionless services for different groups of users with very different networking requirements. The optical buffer and the switch fabric are two of the most important components in an OPS router. In this research, novel designs for the optical buffer and switch fabric are proposed and experimentally demonstrated. In particular, an optical buffer that is based on a folded-path delay-line tree architecture will be discussed. This buffer is the most compact non-recirculating optical delay line buffer to date, and it uses an array of high-speed ON-OFF optical reflectors to dynamically reconfigure its delay within several nanoseconds. A major part of this research is devoted to the design and performance optimization of these high-speed reflectors. Simulations and measurements are used to compare different reflector designs as well as to determine their optimal operating conditions. Another important component in the OPS router is the switch fabric, and it is used to perform space switching for the optical packets. Optical switch fabrics are used to overcome the limitations imposed by conventional electronic switch fabrics: high power consumption and dependency on the modulation format and bit-rate of the signals. Currently, only those fabrics that are based on the broadcast-and-select architecture can provide truly non-blocking multicast services to all input ports. However, a major drawback of these fabrics is that they are implemented using a large number of optical gates based on semiconductor optical amplifiers (SOA). This results in large component count and high energy consumption. In this research, a new multicast-capable switch fabric which does not require any SOA gates is proposed. This fabric relies on a passive all-optical gate that is based on the Four-wave mixing (FWM) wavelength conversion process in a highly-nonlinear fiber. By using this new switch architecture, a significant reduction in component count can be expected.

Abstract:

This study examines how to make trend fashion based ready-to-wear apparels with no fabric waste in the cutting phase through geometric pattern-making. To work with sustainability through geometrical pattern-making in construction, within the context of commercial fashion. The fashion industry is one of the world's top polluters. Several million tonnes of textile ends up in landfills all over the world every year, landfills are overwhelmed and that has a great impact on the environment. The purpose of this study is to investigate how the method of geometric pattern making can have a commercial value in sustainability. How it can bring benefits within fashion design to become more sustainable, and thus help tackle issues in relation to fabric waste in garment production. Significantly, the project discusses if there can be a way of making commercial clothes more sustainable through geometric pattern-making so no fabric is wasted when it is being cut. The work proposes potential solutions and expressions through this chosen methodology.

Abstract:

Fouillée depuis une trentaine d'années, Reims est surtout connue pour son passé antique. Cette étude porte sur l'urbanisation de la ville de la fin du IVe siècle au XIXe siècle. Dans cette perspective la trame parcellaire est à la fois une source et un objet d'étude. La démarche a été pensée comme une démarche archéologique. Il s'agissait d'abord de confronter les formes de l'urbain avec les données matérielles, pour renseigner des éléments qui dynamisent et structurent la ville sur la longue durée.Trois volets ont été abordés. Le premier est d'ordre méthodologique. Il interroge les outils à utiliser et mettre en place pour traiter l'ensemble de l'espace urbain Le second volet consiste en une analyse mutliscalaire de certains objets urbains pour mettre en avant des lieux structurants de la ville médiévale et moderne : réseau viaire, zone humide, quartiers à dominante ecclésiastique ou économique. Dans la lignée des Documents d'Evaluation du Patrimoine Archéologique des Villes Française, la thèse se proposait avant tout de faire un état des lieux des phases d'évolution de la ville. Un chapitre conclusif de modélisation chrono-chorématique permet de faire le point sur les informations traitées et l'évolution des éléments structurants de la ville
Excavated for about thirty years Reims is chiefly known for its ancient past. This work is focused on the city urbanisation from the end of the 4th century until the middle of the 19th century. In this perspective the plot frame is both a source and object of study. In an archaeological approach, I compare the urban forms first with material data, then with ecological data and archieves, to inform elements that drive and structure the city over the long term.Three main approaches were followed. The first one is methodological. It questions tools to create to threat all of the urban space. The second line consists of analysing urban objects from diferent scales to highlight structuring spaces : road network, wet zone, economic or ecclesiastical areas. Like Documents d'Evaluation du Patrimoine Archéologique des Villes Française, the purpose of this study was to the evolution of the city phases. A concluding chapter of chrono-chorematic modeling allows to review the data threated and the evolution of structural elements of Rheims

Abstract:

Grâce à leur géométrie spécifique, faite d'une superposition de couches unidirectionnelles de fibres continues, liées par des coutures plus ou moins complexes, les renforts NCF (Non-Crimp Fabric) possèdent une combinaison de propriétés intéressantes. Ces propriétés permettent l'utilisation de procédés de production tels que le procédé RTM (Resin Transfer Moulding) et permettent l'utilisation des caractéristiques de rigidité élevée des fibres dans la pièce finale. Ainsi, ces renforts trouvent des applications dans différents secteurs de l'industrie des composites et notamment en aéronautique. Les couches, formées de fibres parallèles juxtaposées, sont liées par différents types de coutures. Ce lien conduit à des propriétés différentes de celles observées sur un renfort tissé où les mèches de chaîne et de trame sont liées par entrelacement. Par conséquent, la cinématique de déformation des renforts NCF secs lors de la mise en forme peut être différente. Dans ce travail de recherche, nous menons d'abord une étude expérimentale sur les mécanismes de déformation se produisant lors de tests élémentaires et lors d'une expérience d'emboutissage. Plusieurs renforts NCF et un renfort interlock sont étudiés. Ensuite, nous introduisons un nouveau modèle pour la simulation de la mise en forme du renfort de composite NCF sec. Cette approche implique l'utilisation d'éléments finis lagrangien semi-discrets pour représenter les couches et d'éléments de barres pour représenter les coutures. Ce modèle nécessite un algorithme de contact spécifique pour gérer la relation entre les éléments finis. Une loi de frottement de Coulomb avec seuil de glissement est utilisée. Enfin, le modèle est validé par l'intermédiaire de l'essai de bias test puis la mise en forme sur un hémisphère est simulée et comparée à l'expérience.

Abstract:

The networks in traditional data centers have remained unchanged for decades and have grown large, complex and costly. Many data centers have a general purpose Ethernet network and one or more additional specialized networks for storage or high performance low latency applications. Network convergence promises to lower the cost and complexity of the data center network by virtualizing the different networks onto a single wire. There is little evidence, aside from vendors' claims, that validate network convergence actually achieves these goals. This work defines a framework for creating a series of unbiased tests to validate converged technologies and compare them to traditional configurations. A case study involving two different network converged technologies was developed to validate the defined methodology and framework. The study also shows that these two technologies do indeed perform similarly to non-virtualized network, reduce costs, cabling, power consumption and are easy to operate.

Abstract:

extilindustrin måste ständigt söka nya alternativ inom beläggningar och laminering för att minska den skadliga miljöpåverkan. En fråga som uppkommit är om beläggningar används i större utsträckning än vad som egentligen behövs. Denna kandidatuppsats har skrivits i samarbete med Artex AB och kretsar kring ett befintligt solskydd och solens ljusspektrum som består av strålar mellan 320–2500 nm. Material som bestrålas kan antingen absorbera, reflektera eller transmittera dessa strålar. Strålarnas alternativa vägar adderat med varandra blir alltid hundra procent, vilket innebär att genom att öka den reflekterande förmågan minskas de andra två tillstånden. I denna studie granskas den totala reflekterande förmågan av ljusspektrumet hos textila material som i sin tur beror på många olika faktorer. Det undersöks även om det är ett steg i fel riktning att använda sig av beläggningar för att nå ett bättre högreflekterande material. Detta även för att minska miljöbelastningen. Eftersom beläggningar generellt förstyvar material är detta kontraproduktivt när man vill bibehålla följsamheten hos en tygvara, vilket är avgörande för denna typ av produkt. Skrynkelheten går nämligen hand i hand med tygvarans då stumma yta. Detta projekt fokuserar på solskydd som ska användas inifrån en bil. Syftet med studien var alltså att undersöka om en obelagd vit och tät tygvara kan uppnå tillräcklig funktion för ett solskydd innanför en bil. I experimenten användes fyra olika tygvaror med olika strukturer i bindningarna för att göra en så omfattande studie som möjligt. Dessa fyra var: en satin, en varptrikå och två stycken tvåskaft, varav den ena glesare och mer matt än den andra. Respektive tygvara beströks med ett färgpigment för att analysera om kombinationen mellan reflektion och elastisk potential var möjlig. Tester som genomförts i denna undersökning var: bestämning av färghärdighet, total reflektion, ljustransmittansmätning och ett egenkomponerat skrynkeltest. Vidare granskades dess skillnader för att undersöka om ett vitt material kunde ge en bättre totalreflektion, men även för att bevisa att en tygvaras konstruktion kan erhålla följsamheten även om en beläggning är nödvändig. Mätvärdena granskades för att sedan jämföra, först med varandra och sedan mot ett referensprov som kommer från en befintlig produkt som författarna fick att tillgå från Artex AB. En trikåvaras elastiska förmåga visade sig kunna bibehållas trots ett belagt ytskikt, och visade även på bra totalreflektion. Denna varptrikå uppvisade, tillsammans med satinen, på bra totalreflektion då de var obelagda och hade god följsamhet. I test om totalreflektion visades det att en vit tät tygvara reflekterade större procent än en belagd tygvara i det synliga ljusets spektrum. För att kunna dra slutsatser om ett vitt obelagt tyg med dessa konstruktioner (satin och varptrikå) hade varit bättre för ett solskydd hade vidare undrsökningar behövts göras. Detta för att se hur mycket av den totala reaktionen som är diffus respektive spekulär
The textile industry must always find ways to reinvent itself and look for alternative options, as the coating and lamination industries are vital for a better environment. A question that needs answering is if coating on textiles are used more than needed. This bachelor thesis is written in cooperation with Artex AB and revolves around the suns light spectrum that consists of rays of 320 to 2500 nm. Materials that irradiate can either absorb, reflect or transmit these wavelengths. The rays alternative routes added with each other is always one hundred percent, which means that through increasing the reflecting capacity the other two will decrease. The most interesting part of this study, was to examine the ability of the light spectrum for material, and take in to consideration it’s construction, structure and color. Textile materials are often coated to add qualities and, in this case, to increase reflecting quality. This study is trying to prove, that it's a step in the wrong direction when it comes to the functionality of a sunshade product and for a reduced impact on the environment. As coating generally stiffens materials it’s contuerproductive with regards to keeping the resilience for the fabric, which is decisive for this type of product. The wrinkles go hand in hand with the fabrics coated surface. Since this project focuses on an existing sunshade product that will be used inside of a car, the heat radiation and the undulations within a certain wavelength that requires reflection will be focused on. The purpose with the study was to examine if an uncoated white fabric can achieve the same function in a sunshade as the current fabric in the product. In the experiments, four fabrics with different structures were used to complete such a comprehensive study as possible. These four fabrics were: one satin, one warp knitted and two plain weave, where one of them was more faint and sparse than the other. Each fabric was coated with a color pigment to analyze the possibilities of a high reflective material that still has elastic potential. The tests that were made was: determination of color fastness, total reflection, light transmit and a wrinkle test. Further on these differences were reviewed, and then concluded that the coating, in hope of increasing the reflection, is negligible. But also, to prove that a fabrics construction can keep its resilience even with a coated surface. These values have been reviewed and then compared with each other and against a reference fabric that the writers took part of from Artex AB. A warp knitted fabric was able to maintain its elastic ability regardless of a coated surface, and also shows good total reflection. This warp knitted fabric showed, together with the satin, good total reflection when they were uncoated and had good resilience. In this test for total reflection, it was proven that a white dense fabric reflects better than a coated fabric in the visible spectra of light. To be able to conclude if a white uncoated fabric with these constructions (satin and warp knitting) would be more useful for a sunshade, further studies had to be made, to see how much of the total reaction that is diffuse and specular.

Full text

Abstract:

This work addresses the use of an electromagnetic wave sensor to determine moisture content within building fabrics. Building materials that require a special mixing ratio such as concrete, mortar and membrane layers will be subject to significant effects when exposed to unpredictable weather changes owing to the excess of the acceptable moisture content. The acceptable moisture content level varies with various building fabrics and exceeding this level will affect the overall performance of building constructions. The project proposes using a novel electromagnetic (EM) sensor to monitor, in a non-destructive manner, the signal reflected from building structures in real time to determine exceeded moisture content level. This project involves the design and construction of an EM sensor operating at two frequency ranges: 2GHz to 6GHz and 6GHz to 12GHz at a power of 0dBm. This research is a new approach for monitoring moisture in buildings which has not been investigated before. The simulation software High Frequency Structure Simulator (HFSS) was used to model the microwave sensor. The pyramidal horn antenna was chosen as the preferred antenna for this work owing to higher gain, directivity and overall performance. Different building materials and structures have been made in a laboratory environment to determine the levels of moisture content, as well as to determine the modes of building fabrics failures owing to membrane failure, a pipe burst and ground source. Finally, a graphical user interface was developed and used to control the sensor parameters as well as frequency sweep, to capture the data from the sensor. Based on the findings of this project, the EM wave sensor could be used to determine the moisture content of building fabrics in a non-destructive manner.

Full text

Abstract:

Primary crops are linked to final consumption by networks of processes and actors that convert and distribute food and non-food goods. Achieving a sustainable metabolism of this bio-economy is an overarching challenge which manifests itself in a number of the UN Sustainable Development Goals. Modelling the physical dimensions of biomass conversion and distribution networks is essential to understanding the characteristics, drivers and dynamics of our societies' biomass metabolism. In this paper, we present the Food and Agriculture Biomass Input-Output model (FABIO), a set of multi-regional supply, use and input-output tables in physical units, that document the complex flows of agricultural and food products in the global economy. The model assembles FAOSTAT statistics reporting crop production, trade, and utilisation in physical units, supplemented by data on technical and metabolic conversion efficiencies, into a consistent, balanced, input-output framework. FABIO covers 191 countries and 130 agriculture, food and forestry products from 1986 to 2013. The physical supply-use tables offered by FABIO provide a comprehensive, transparent and flexible structure for organising data representing flows of materials within metabolic networks. They allow tracing biomass flows and embodied environmental pressures along global supply chains at an unprecedented level of product and country detail and can help to answer a range of questions regarding environment, agriculture, and trade.

Abstract:

During the last decade medical applications of textile sensors have been growing rapidly and textile sensors are the focal research point for many sensor projects. Textile sensors are still not available as a mainstream product to replace conventional electric sensors and electrodes. Textile sensors can be integrated in a textile garment to measure vital signs of a human being. In this regard stretch sensors are able to measure breathing rate of a person. In this project we use seamless knitting technique to make stretch sensors using conductive fibers. The resistance difference between stretching and relaxing of these sensors gives a pattern for human breathing. Four knitting structures with different conductive fibers are made and tested with cyclic tester to construct a graph between resistance and time to find the knitting structure which gives the best results. Tests are also done to check the results after washing. These sensors can be used in breathing monitoring of patients during daily life.

Abstract:

Since its independence in 1984, politicians and nationalists in Brunei Darussalam have appealed to traditions in their efforts to create a national identity based on Brunei Darussalam’s national philosophy, `Malay Islamic Monarchy’. Weaving is one of the traditions related to Brunei traditional culture, thus traditional textile is used to construct national identity. This study focuses on the role played by powerful institutions in the creation of new tradition in order to foster national awareness in the `new state’ of Brunei Darussalam and I examine how traditional textiles are incorporated into the project of nation building. In Bruneian society, traditional woven cloths have multiple roles whose meanings vary according to the situation in which the traditional cloth is utilized. This research explores the significance of traditional textiles in Brunei Darussalam, focusing on the consumption of locally woven textiles in its traditions and the relationships to the expression and construction of identity. Since Islam came to Brunei Darussalam, it has become one of the predominant markers of identity of the Malays. This study analyse the influence of Islam in the production and consumption of traditional textile in Brunei Darussalam. The continuity of the production and consumption of traditional woven textile in Brunei Darussalam is very much dependent on its significant in the traditions of Brunei society as a whole. In order to prove this, this study focuses its investigation upon the production and uses of traditional textiles in the social customs of Malay society in Brunei Darussalam. Traditional woven textiles are employed to construct social identity in the reproduction of distinction. Traditional textiles are also offered to signify privilege and power. I examine how traditional textile is being used to distinguish social status and political prominence, denote offices, and display wealth and prestige.

A tese intitulada Memória do Operariado Amazonense: a festa como constructo humano e expressão da subjetividade operária , trata de um estudo sobre os trabalhadores do Polo Industrial de Manaus que, em meio às tensões do regime no início dos anos oitenta e das agruras do controle fabril, soube organizar-se para constituir-se numa classe social, a classe operária. Buscamos compreendê-lo na trama de relações e dos antagonismos de classe que notabilizaram este período. Assumiu o propósito de resgatar os fragmentos e retalhos da vida e trabalho dos trabalhadores amazonenses, a expressão de suas subjetividades na manifestação da festa operária, ocorrida no interior das fábricas que compõem o Polo Industrial de Manaus, na década de oitenta do século XX e suas implicações no processo de transformação, transcendência e hominização dos trabalhadores congregados nos atos festivos. O estudo atende a uma perspectiva metodológica da história oral e a técnica utilizada constituiu-se na entrevista do tipo semi-estruturado aplicada junto a onze trabalhadores do Polo Industrial de Manaus. Realizamos uma análise sobre a reinvenção da subjetividade operária e a luta de classe; a reconstituição da ontologia do discurso operário no fazer-se classe, procurando revelar o lugar da memória dos trabalhadores amazonenses, buscando identificar os primeiros protagonistas da luta operária, os antagonismos e a construção do novo sindicalismo e das greves segundo a narrativa dos operários; a festa como expressão da luta operária, constitui-se como instrumento de visibilização da greve, expressão cultural, transgressão e carnavalização e, por último, a reinterpretação da festa como reinvenção do operariado, traduzindo os sentidos da festa para a organização sindical, alguns apontamentos sobre o trabalho nos anos 1990 e os novos rumos do sindicalismo no Brasil e no Amazonas. A realização desta pesquisa deveu-se à necessidade e, também, à preocupação de recuperar a memória do operariado amazonense cuja meta fundamenta-se na ideia de contribuir para com a produção dos estudos da memória histórica regional, apresentando subsídios à comunidade acadêmica no discutir de uma visão historiográfica dando vez, voz e lugar aos sujeitos históricos do seu tempo.

Full text

Abstract:

A pair of high-stability optical frequency references has been developed. The devices are based on room temperature Fabry-Perot cavities with mirrors spaced apart by a hollow single-crystal sapphire element. The sapphire element delivers mechanical sti ness that provides improved immunity to vibrational perturbations compared with the more common spacers made from ultra-low expansion glass. The system is housed in an vacuum chamber designed to provide isolation from environmental perturbations through the use of an active thermal control system, suspension legs and a unique beam alignment system. The dimensional stability of the Fabry-Perot was translated into a highly stable laser frequency by frequency locking a 1064nm Nd:YAG laser to the centre of a mode of the cavity. This frequency lock was implemented by the Pound-Drever-Hall scheme. By careful design, this control system was able to hold the frequency of the laser to within parts in 1016 of the frequency of the fundamental cavity mode. The minimum fractional frequency stability of the laser frequency was measured at 2.1x10[-]14 for integration times of 0.8 s, limited by the residual instability of the Fabry-Perot cavity. The experimental methods used to measure the performance of the system have also been considered in depth. For example, the most common way of characterizing the frequency stability of a frequency standard is the Allan variance. It is demonstrated that, without care, data taken with modern frequency counters can produce erroneous and distorted results when their output is supplied to this algorithm. The method to avoid or account for these errors is also presented. The Fabry-Perot cavity performance is limited on long timescales by residual temperature uctuations, which can be ameliorated in future by enhancing the design of the thermal control system. At short timescales, the system is limited by vibration-induced uctuations together with a white noise source, that is yet to be identi ed, but may relate to fundamental thermodynamic temperature uctuations of the sapphire spacer. This system was used to measure the stability of an optical signal synthesised from a cryogenic microwave sapphire oscillator using an wide-band optical frequency comb. This was the rst demonstration of a multiplication of an ultra-stable signal from the microwave frequency domain into the optical frequency domain, without loss of delity at the level of 2x10[-]14.

Abstract:

À partir de deux opérations d’agrandissement de ville au XVIIe siècle (Aix en 1646, Marseille en 1666), cette recherche vise à comprendre les modalités concrètes de production de l’espace urbain sous l’Ancien Régime, à la fois au plan humain et matériel. Cette étude débute au ras du sol, à l’échelle la plus fine de la matérialité urbaine, à savoir le parcellaire. À partir d’une réflexion croisée autour des droits du sols et du marche de l’immobilier, l’enjeu ici est de mieux comprendre le poids des structures et des mécanismes juridiques privés dans les processus de fabrique de la ville. Changeant d’échelle d’analyse, un ensemble d’interrogations liées au domaine de l'économie du bâtiment permet de mettre en évidence les modalités économiques, sociales et juridiques qui entourent les chantiers de la construction. Le but ici est à la fois de dégager les règles cadrant l'activité constructive, et de déterminer les contours de la pratique des individus dans ce domaine. Cet axe induit une réflexion autour de la structuration à la fin du XVIIe siècle d’un ordre public constructif. Enfin, cette recherche aborde dans un troisième temps l’espace urbain dans son ensemble le plus vaste, à la fois sur le plan matériel et administratif. À partir des cadres politiques et institutionnels sollicités et déployés pour mener à bien ces opérations, c’est la question de l’intégration et de la gestion de ces nouveaux espaces à l'ordre urbain existant qui nous préoccupe
From two city expansion operations in the seventeenth century (Aix in 1646, Marseille in 1666), this research aims to understand the practical arrangements for production of urban space under the old regime, both in human terms and equipment.This study begins at ground level at the finest scale of urban materiality, the plot. From a cross-reflection on the rights of the land and property market, the challenge here is to understand the weight of structures and private legal mechanisms in urban process.Changing scale of analysis, a set of questions related to the building of the economy domain allows to highlight the economic, social and legal conditions surrounding the sites of construction. The goal here is both to identify the rules framing constructive activity and to determine the contours of the practice of individuals in this area. This axis induces a reflection on the structuration of a constructive public order at the end of the seventeenth century.Finally, this research addresses urban space in its larger whole, both hardware and administratively. From the institutional and public frameworks to carry out these operations, the issue of integration and management of these new spaces to the existing urban order came up

Doutoramento em Arquitectura
Os modelos dos edifícios funcionais do princípio do século XX fundem-se e moldam-se num cruzamento inter-atlântico de influências tecnológicas. De facto, os sistemas de construção em betão armado, com todas as variáveis de experimentação científica, contribuíram para uma estandardização da indústria da construção bem como das práticas profissionais a ela associadas, originando uma corrente de proto-modernidade essencial à formação do espírito moderno. As obras funcionalistas dos primeiros quinze anos do século XX resumem em si práticas profissionais que mais tarde serão negadas pelos mestres do modernismo enquanto parte dos processos da construção moderna, mas cujo “estilo” resultante é por estes celebrado. Constituem-se essencialmente de edifícios fábrica, construídos em betão armado, conjugando níveis de performance e de operacionalidade que resumem a função última a que se destinam. A prática do arquitecto moderno europeu, oferecendo resistências a uma total modernidade consagrada em teoria, permitiu a sobrevivência da arquitectura enquanto prática artística, face a um outro lado da profissão, de carácter mais pragmático e assente no princípio do corporativismo liberal.
Models of functional buildings at the beginning of the 20th Century were embedded and moulded in the inter-Atlantic blending of technological influences. In fact, building systems in reinforced concrete, with all their variables in scientific experiments, helped towards standardizing the building industry as well as the way in which professional activity was undertaken. They thus gave rise to a protomodernity current that was essential in shaping the modern spirit. The functionalist buildings appearing in the first fifteen years of the 20th Century are a testimony of the kind of professional practices that would later be condemned by the masters of modernism, for the part these edifices played in modern building processes, but whose resulting “style” would nevertheless be celebrated by the European masters. They mostly came in the form of factory buildings in reinforced concrete, conjugating levels of performance and operativeness that sought to satisfy the main aim for which they had been built. By offering resistance to the Modernity consecrated in theory, the practice of the modern European architect allowed architecture to survive as an artistic practice, as opposed to a more pragmatic nature of the North American architect.

Abstract:

The clothes and domestic textiles of the sixteenth century were, next to food, one of the absolute necessities for humankind to survive. This study examines the different types and constructions of textiles closely, using an historical approach, reading original documentation and viewing the scarce fragments of remaining examples. Due to the class of society being considered and the fragility of the textiles, other rare samples, from beyond the sixteenth century needed to be considered to try and assemble a true picture of the textiles available. Agriculture, demography, geography and history have all been drawn upon. The lack of actual samples and the chasm in information regarding these forgotten items of daily living have been continually assessed and evaluated. Other themes addressed include: the relationship of the yeoman in society through sumptuary law; their respect for and association with nature for raw materials; and innovation in improving their skills. Practical attempts to reveal an authentic colour palette of the yeoman world, although not conclusive, have permitted a fresh approach for further enquiry. This research includes detailed worksheets and various hand woven samples which support the practical element of this study, giving a valuable foundation for further investigation. This original work will be of educational value in portraying this sector of society, so easily overlooked because of the grandeur of the sixteenth century nobility. The samples provide tactile experiences reinforcing, the need of textiles to be 'fit for purpose'. Many skills from this period have been lost to future generations, only recreations based on balanced and empiric judgements will help evaluate the of these forgotten fabrics

Abstract:

Ce travail de thèse porte sur l’étude, le développement et l’analyse du couplage hydro-mécanique mis en jeu pendant le procédé d’infusion de résine (LRI) pour la fabrication de matériaux composites. Un modèle mathématique de ce procédé basé sur une caractérisation expérimentale réduite des propriétés mécaniques et d’écoulement des renforts fibreux est présenté. Le modèle considère un problème à frontière libre en couplant la loi de Darcy avec l’équation de conservation de la masse. Des solutions analytiques de l’évolution de la position du front d’écoulement, des profils de pression de fluide et d’épaisseur sont obtenues pour des écoulements unidirectionnels. Une solution pour des écoulements bi-directionnels est également obtenue en combinant des méthodes éléments finis et levelset. Les solutions uni- et bi-directionnelles ont été validées expérimentalement, un accord raisonnable est obtenu. Les fonctions qui relient l’écoulement, au travers des paramètres de position du front et de la perméabilité, et la déformabilité transverse du renfort fibreux ont été obtenues. Ainsi, la conservation de la masse combinée aux conditions aux limites permet d’obtenir une solution simple de l’évolution du front d’écoulement et des profils de pression et d’épaisseur d’une pièce composite infusée
This thesis describes the study, analysis and development of a methodology to tackle hydro-mechanical coupling involved during Liquid Resin Infusion process. During the researches the new mathematical model of the LRI process for composites manufacturing using a reduced experimental characterization of mechanical and flow properties of fabric was presented. The mathematical modeling has been considering the moving-boundary problem, coupling Darcy's law with the continuity equation. An analytical solution of flow front progression, pressure distribution and thickness evolution has been achieved in 1D. A 2D flow was achieved using combination of finite element and level-set methods for numerical modeling. Proposed analytical and numerical models have been validated against experimental data, reasonable agreements have been achieved. The relationships which links fluid flow (permeability and flow extent) and induced thickness variations have been derived. Consequently, mass conservation together with additional boundary condition gives simple and effective way to find a pressure profile within a part being infused

Full text

Abstract:

L'urbanisation est principalement due à la croissance démographique, à l'exode rural et au changement du mode de vie. Ce processus augmente les terres artificielles, qui affectent la biodiversité, les écosystèmes, le climat urbain et réduit les terres pour l'agriculture et les espaces naturels. L'objectif de cette thèse est de simuler divers scénarios d'urbanisation afin d'améliorer la prise de décision en matière de politiques publiques. Pour ce faire, le modèle SLEUTH est utilisé afin d’évaluer l’impact des bâtiments et des règles environnementales sur l’étalement urbain. Dans la méthode utilisée, SLEUTH intègre davantage des données topographiques, des données sur les tissus urbains et démographiques, y compris les caractéristiques géographiques et les contraintes environnementales. Le principal défi de cette recherche est de proposer différents scénarios d'étalement urbain pour plusieurs types de règles environnementales tout en tenant compte du besoin des habitants ou du moins d'une estimation de la croissance de la population. Le modèle SLEUTH est l’un des modèles de simulation d’automates cellulaires bien connus, qui correspond à la simulation dynamique de l’expansion urbaine et s’adapte au modèle morphologique de la configuration urbaine. SLEUTH, comme beaucoup d'autres méthodes de simulation de la croissance urbaine, ne considère que les données historiques. Bien que les impacts de la croissance démographique et du tissu urbain soient implicitement pris en compte lors de la phase d'étalonnage sur les cartes urbaines historiques, il est impossible d'inclure les changements de taux de croissance démographique ou de types de bâtiments dans les simulations. De plus, les résultats de SLEUTH se limitent à des données matricielles difficiles à interpréter pour les décideurs. Les résultats sont des pixels, sur lesquels une urbanisation est supposée se produire, ce qui n’a pas de sens du point de vue de l’urbanisme. Par conséquent, notre recherche vise à diversifier les possibilités de simulation en intégrant explicitement le facteur des types de bâtiments en fonction de la croissance de la population et en fournissant des modèles de visualisation des résultats de scénarios de croissance urbaine en 2D et même en 3D.Afin d'améliorer les résultats de SLEUTH, différents scénarios de simulation de croissance urbaine en 2D ont été définis sur la base du modèle SLEUTH en ajoutant le type de bâtiment et l'estimation de la croissance démographique en tant que facteurs du tissu urbain. Chaque simulation correspond à des politiques plus ou moins restrictives en espaces considérant ce que ces territoires peuvent accueillir en tant que type de bâtiment et en tant que population globale. De plus, les simulations peuvent aider l’utilisateur à protéger les terrains souhaités, tels que les espaces environnementaux, de l’urbanisation. Ces scénarios montrent la force de la simulation du modèle et permettent d’améliorer notre compréhension de l’étalement urbain. Trois études de cas de tailles et de populations différentes sont utilisées, Toulouse Métropole, Saint Sulpice la Pointe et Rieucros, afin de donner une idée de l'efficacité de la méthode proposée à plusieurs échelles. L'évaluation des résultats indique que la méthode proposée est capable d’effectuer différentes simulations correspondant à plusieurs priorités et contraintes foncières. Il est utile de voir quels terrains peuvent être protégés (où) et quel type de bâtiment peut être utilisé pour limiter l'étalement urbain (combien). Une représentation en 3D de chaque simulation de croissance urbaine est fournie afin de faciliter l'interprétation de la simulation SLEUTH et de différencier les scénarios. Les résultats permettent d’avoir plusieurs images de la ville de demain pour l’appliquer aux politiques urbaines
The process of urbanization occurs mainly due to population growth, rural exodus to cities and life style that often induces the nearly irreversible changes. It increases the artificial lands, which affect the biodiversity, ecosystems, urban climate, and reduces land for agriculture and natural areas. The focus of this thesis is to simulate diverse urbanization scenarios in order to improve public policies decision making. To do this, the SLEUTH model is used in order to investigate the impacts of buildings and environmental rules on urban sprawl. In the method used, the SLEUTH model integrates more topographic data, urban tissue and demographic data, including geographical features and the environmental constraints. The main challenge of in this research is to propose different urban sprawl scenarios for different kind of environmental rules while taking into account the population demand or at least population growth estimation. The SLEUTH model is one of the well-known cellular automata simulation models, which matches the dynamic simulation of urban expansion and adapts to morphological model of the urban configuration. SLEUTH, like many other urban growth simulation methods, considers only the historical data. Although, the impacts of population growth and urban tissue are implicitly considered during the calibration phase on the historical urban maps, changes in population growth rate or in building types cannot be included in its simulations. Moreover the SLEUTH results are limited to raster data that are difficult to interpret for decision makers. The results are some pixels on which urbanization is supposed to occur which do not make sense from urbanism point of view. Therefore, our research aims to diversify the simulation possibilities integrating explicitly factors of building types according to population growth and providing visual methods to view urban growth scenario results in 2D and even 3D. In order to improve the SLEUTH results, different 2D urban growth simulation scenarios have been defined based on the SLEUTH model by adding buildings type and the estimation of the population growth as urban fabric factors. Each simulation corresponds to policies that are more or less restrictive of spaces considering what these territories can accommodate as a type of building and as a global population. In addition, the simulations can help the user to protect the desired lands such as the environmental spaces from urbanization. These scenarios show the simulation capabilities of the model and make it possible to improve our understanding of an urban sprawl simulation.Three different case studies with various sizes and populations are used including Toulouse metropolitan, Saint Sulpice la Pointe and Rieucros to provide a view of the effectiveness of the proposed method on several scales. The results evaluation indicates that the proposed method makes different simulations that correspond to different land priorities and constraints. It helps to see which land can be protected (where) and how building type can be used to constrain urban sprawl (how much). A 3D representation for each prospective urban growth simulations is provided in order to facilitates the interpretation of the SLEUTH simulation and differentiate the scenarios. The findings allow having different images of the city of tomorrow for applying it to urban policies

Abstract:

This thesis presents teaching fundamentals of digital logic design and VLSI design for freshmen and even for high school students using e-textiles. This easily grabs attention of students as it is creative and interesting. Using e-textiles to project these concepts would be easily understood by students at young age. This involves stitching electronic circuits on a fabric using basic components like LEDs, push buttons and so on. The functioning of these circuits is programmed in Lilypad Arduino. By using this method, students get exposed to basic electronic concepts at early stage which eventually develops interest towards engineering field.

Abstract:

L’objet de ce travail est l’évaluation du processus de vieillissement et de la durabilité des tissus techniques utilisés en ingénierie de construction. Deux types de tissu en polyester enduit de PVC ont été testés: VALMEX vieilli naturellement et AF9032 soumis au vieillissement accéléré. L'impact du processus de vieillissement a été observé en analysant les changements des valeurs des paramètres des modèles constitutifs: linéaire par morceaux, viscoélastique de Burgers et viscoplastique de Bodner-Partom. La comparaison de tissu VALMEX utilisé pendant 20 ans à l’Opéra de la Forêt à Sopot et du même tissu stocké à l’abri a montré que la matière, après 20 années de fonctionnement, a conservé ses propriétés mécaniques et pourrait être encore utilisée pendant plusieurs années. Le vieillissement dû aux conditions environnementales d’exploitation a provoqué une augmentation de la rigidité du revêtement (PVC), alors que la raideur des fibres en polyester est restée pratiquement inchangée. Le tissu AF9032 a été soumis au processus de vieillissement accéléré. Les échantillons de tissu ont été placés dans une chambre thermique à 80 et 90 °C durant 12 semaines. Les variations des paramètres des modèles constitutifs en fonction de temps de vieillissement ont pu être exprimées par des relations linéaires. Les résultats de vieillissement thermique accéléré ont été extrapolés d’après la méthode d’Arrhenius pour obtenir des valeurs correspondantes au vieillissement naturel. Pour les deux cas de vieillissement, les changements plus importants se sont produits dans la direction de la trame. Pour les fils de chaîne, les différences sont beaucoup plus petites et parfois négligeables
This thesis describes the investigation on the durability of technical fabrics that are commonly used as the constructional-covering material for engineering structures. Two types of polyester reinforced PVC coated fabrics have been subjected to the exploitation ageing (VALMEX fabric) and the artificial, laboratory ageing (AF9032 fabric). The influence of the ageing process has been presented as the parameters evolution of the following constitutive formulations: the piecewise, the viscoelastic Burgers and the viscoplastic Bodner-Partom models. The comparative analysis between two types of the VALMEX fabric (the material used for 20 years on the structure of the Forest Opera roof and the not used one – kept as a spare material) have been conducted. The obtained results have shown the very good performance of the material used outdoor and indicated that it could still work satisfactorily for the next several years. The accelerated ageing of the AF9032 fabric has been performed at the elevated temperature of 80°C and 90°C in a thermal chamber for up to 12 weeks. The achieved parameters values versus ageing time have been approximated by linear functions. The results of the thermal ageing have been extrapolated using the Arrhenius methodology. The both types of ageing have significant influence on the mechanical properties of the tested fabrics for the fill direction while the warp direction is free of this effect. As a result of the performed identifications the parameters of three constitutive models have been obtained. They can be implemented for the numerical simulation of the polyester reinforced PVC coated fabrics performance and help to predict their life span under service conditions

Abstract:

L’aéroport est un objet géographique protéiforme, caractérisé par son « obsolescence accélérée » (BANHAM, 1962). Depuis les années 1990, son ultime mutation s’articule autour d’un processus de diversification fonctionnelle engendré par l’injection d’activités nouvelles, parfois éloignées du transport aérien, dans l’objectif d’accroître les profits et la rentabilité de l’infrastructure dans un contexte de privatisation généralisée. Cette évolution concerne les plus grands hubs mondiaux, notamment Paris-CDG, quatrième aéroport du monde selon le trafic passagers international. Cette tendance, qui a donné naissance au concept opérationnel d’airport city, tel qu’il est désigné par les observateurs et opérateurs anglo-saxons, attise doublement la curiosité géographique. En premier lieu, parce qu’elle interroge la fonction première de l’infrastructure de transport qu’est l’aéroport, qui devient alors un objet spatial non identifié qu’il convient de redéfinir. En second lieu, parce que cette désignation d’airport city, traduite par les opérateurs francophones par ville aéroportuaire, interroge la ville et surtout ce qui fait la ville dans ses dimensions matérielle et idéelle, c’est-à-dire l’urbanité et la citadinité. Suffit-il d’injecter des fonctions urbaines dans un espace pour en faire de la ville ? La ville aéroportuaire n’est-elle qu’une ville fonctionnelle ? En s’efforçant d’évaluer la pertinence géographique de la notion d’airport city, cette thèse impose de faire de l’urbanité et de la citadinité des concepts opératoires afin de les confronter au terrain aéroportuaire. Elle s’efforce également de replacer l’aéroport au centre de l’étude géographique en proposant un ajustement de l’échelle d’observation à l’ensemble de la zone aéroportuaire, évitant ainsi la synecdoque particularisante réduisant l’aéroport au terminal. Dans l’évaluation de la citadinité, elle a également pour objectif de saisir les spatialités de l’ensemble de la société aéroportuaire (passagers, employés, accompagnants, SDF, etc.)
Airports are protean geographical objects characterized by their « accelerated obsolescence » (BANHAM, 1962). Since the 1990s, their final transformation has been structured around a process of functional diversification engendered by new activities, which are sometimes very different from air transport, in order to increase the infrastructures’ profits and profitability in a context of widespread privatization. The world’s largest hub airports are concerned by this evolution, especially the Paris-Charles-de-Gaulle airport, the world’s fourth busiest airport by international passenger traffic. This trend, which has given birth to the operational concept of airport city, as the Anglo-Saxon operators and observers call it, stirs up the geographical curiosity in two ways. Firstly, it questions the primary function of airports, which become unidentified spatial objects that need to be redefined. Secondly, the concept of airport city questions the city itself. Indeed, what makes a city a city on a material (urbanity) and conceptual (“citadinity”) level? Can a space with urban functions be considered as a city? Is the airport city only a functional city? By assessing the geographical relevance of the concept of airport city, this thesis aims at making the concepts of urbanity and “citadinity” operational concepts, so as to compare them with the airport ground. By adjusting the observation scale to the whole airport area, it also replaces the airport at the centre of the geographical study. Thus, the airport is not simply viewed as a terminal. Finally, this thesis aims at understanding the whole airport society’s spatiality (passengers, employees, accompanying people, homeless people…) by assessing the concept of “citadinity"

The text brings the analysis of aspects of the literary discourse as the processes of construction of the scenes and the magical universe, in which the narratives of Marina Colasanti are realized, having as it shows the tales of the works Doze reis e a moca no labirinto do vento (2006): "The woman ramada", Uma ideia toda azul (2006): "Beyond the frame", "Between the leaves of green ó" and "Yarn after yarn". The general and specific objectives are to highlight and distinguish the encompassing and generic scenes present in the narratives, to identify the nature of the verbal sign in its relation to the nonverbal sign, and to analyze intertext resources, paratext, among others, as an artistic procedure. The narrative plans are approached, in which the characters are realized mimically, starting from the initial assumption formulated by Dominique Maingueneau. Non-verbal language is an invitation to read verbal language and vice versa. Both are associated with the signs that are constructed through the textual writing: loom and fabric. They can be seen now either explicitly or implicitly, and put in the service of a power that is realized by the act of reading. Thus, in the narrative text, there are traces of a speech in which the text is staged.
O texto traz a análise de aspectos do discurso literário como os processos de construção das cenas e o universo mágico, em que se realizam as narrativas de Marina Colasanti, tendo como mostra os contos das obras Doze reis e a moca no labirinto do vento (2006): “A mulher ramada”, Uma ideia toda azul (2006): “Além do bastidor”, “Entre as folhas do verde ó” e “Fio após fio”. Os objetivos geral e específicos são destacar e distinguir as cenas englobante e genérica presentes nas narrativas, identificar a natureza do signo verbal na sua relação com o signo não verbal e analisar recursos de intertexto, paratexto, entre outros, como procedimento artístico. Abordam-se os planos narrativos, nos quais se dá a realização dos personagens mimeticamente, partindo do pressuposto inicial formulado por Dominique Maingueneau. A linguagem não verbal é um convite à leitura da linguagem verbal e vice-versa. Ambas se associam aos signos que se constroem por meio da escritura textual: tear e tecido. Elas podem ser vistas ora de modo explícito, ora implícito, e se colocam a serviço de um poder que se realiza pelo ato de leitura. Assim, no texto narrativo, há rastros de um discurso em que o texto é encenado.

“Urban fabric” definition is the spatial network order which weaves by the urban space and the building. Urban fabric is the urban structure gene which may reflect the urban function, the industry condition, the urban landscape, the urban image and affect the urban appearance specifically presents. By the development of urban fabric, we can find the ecology characteristic and historical significance of an urban, which affects inhabitant's sympathy and the ownership feeling direct or indirectly. The Changhua city was the first city which formed city streets with urban function in the middle area, and held the important status in the middle area of Taiwan in early times; in recent years, the urban development difference is large at the area of the train station around. The advance station area is the main central business district in Changhua city. While the latter station area is cut off the railroad, the urban development is unable to extend to the west side, and creates the phenomenon of local development slow. Therefore, this research is designated the Changhua train station peripheral locality to be the urban fabric research scope, and constructs and analyzes the urban fabric, discusses the origin of, investigates and analyzes the residents’ degree of satisfaction about the urban fabric as well as proposes the fabric improvement strategy to construct and improve the urban fabric of the area for the urban designers. The induction of affecting the Changhua train station peripheral locality urban fabric origin may be divided into two big factors "the urban plan and the transportation construction". About the Changhua train station peripheral locality, the time from the plan announced to the plan actualized examining comprehensively was too long, so that the urban land utilization plan and present development difference is big. Moreover, it is due to the railroad with place cut off, so the urban fabric development around the station is far different. Finally, according to urban fabric key point of the construction: the compatibility, the feasibility, the accumulation and the identification, I propose the topic of this area urban fabric construction — public space constructed not well, parking space supply and demand unbalance, being short of the crosswalk space, the historical space and the urban development construction disconnected, the whole building landscape not discordant, the development around station unbalanced.

Abstract:

The very foundation of transportation relies on its ability to efficiently move people and goods through a transitional space. Transportation hubs are key to achieving this goal. However, many transit terminals are outdated or poorly designed to fit the needs of the modern world. At the core of this thesis are two overarching questions. First, how do we design intermodal transit terminals so that they successfully integrate into an existing urban fabric? Second, how do we design for innovative modes of transportation, such as hyperloop technology? This thesis explores how architectural design can recover existing transit connections within an urban context and provide new modes of transportation for a faster and more efficient user experience. Exploring the current issues within the transit sector today was a major focus of this research as well as selecting a site within an active city center. Furthermore, research into the emergence of new modes of transportation, like hyperloop technology and autonomous vehicles helped to identify potential transit solutions. Much of this research investigated the history of transit centers in addition to studying several important case studies that facilitated a solution to improving transit connections. Several design options were explored through this research and a selected design was integrated into a final design solution to help lay the path for a more efficient future in transit architecture.

Abstract:

This research includes a preliminary study prior to the commencement of the Ph.D. work and three phases of design, construction and testing of three generations of moment-shaped beams. Each phase of the research brought a better understanding of curved beams which follow the shape of the moment diagram. The moment diagram in this study was for simply supported beams supporting a uniformly distributed load as would be the case in the majority of building designs. The original theory for this research can be described as follows: Moment-shaped beams are the natural outcome of a fundamental understanding of stress paths in a horizontal load bearing member. By following these stress paths we may provide materials where required to most efficiently carry the compression and tension stresses to the supports. Allowing stresses to follow their naturally desired paths reduces regions where stresses cross paths called disturbed regions. The outcome of the final phase of this research was the development of the third generation of curved beams with a camber. These beams, designated as Cambered Curve beams (CCBs), exhibited the same behaviour as the rectangular control beam design using CSA-A23.3 up to the serviceability failure of L/360 (12mm). The CCB moment-shaped beams require 20% less concrete and 40% less reinforcing steel (no shear stirrups) to carry the ultimate load which is only 12% less than that carried by the CSA-designed control beam. Due to a closed system of internal forces, the moment-shaped beams remain intact and are able to sustain self weight, even after total failure. A significant part of this research was to modify and verify a FORTRAN-based finite element analysis program: FINIT-Y. This program was reconstructed to analyse a full size beam, and enabled the researcher to model and correctly predict the maximum load, crack pattern and failure mode. This study found that moment-shaped beams with no shear reinforcement have the same stiffness and load carrying capacity as the CSA-designed rectangular control beam with shear reinforcement up to serviceability failure (L/360). The study also found that moment-shaped beams have significantly lower ductility at the ultimate load.

Apparel industry is a labor intensive industry. The nature of this industry causes the movement of it is mass production from developed country to cheaper labor cost countries or areas irreversible. While most of traditional apparel manufactures of Taiwan move overseas or seeking for international sourcing, the lady’s underwear industry, especially foundation garment or shapewear industry keeps blooming. The same trend occurs in other developed countries, such as USA and Japan. As new fibers and fabrics continuous are developed, demand of foundation garment which combines fashion, comfort, and shape figure function grows tremendously. The actual shape function, positive and side effects on skeletal muscle, skin, and movement ability, need to be evaluated scientifically. The purposes of this research focus on evaluation of characteristics of elastic fabrics related to physical properties of the construction design of foundation garment and fabric. The main assessment items of elastic fabric in this research are breathability, coverage factor, moisture absorption, elongation and tenacity at break. According to experimental design, this research used analysis variance and multiple comparison method to analysis experimental data. Also study the patent to conclude the developing trend and designing. Based on the final experimental data, the moisture absorption is not noticeable. But breathability and others physical properties of the fabric and garment are conspicuous. This result indicates that it depends on the proportion, construction, density and coverage of the fabric. As the trend of patent, shows that more and more foundation garment been developed. The main function of the foundation garment and shape wear is to carry and shape the body. The patent map analysis shows that for convenience of the design focus on the top section of the body.

Vascular grafts are used to replace the impaired native blood vessels, and thus play a significant role in clinical surgery. Making small-diameter vascular grafts that have a match in mechanical properties of blood vessels thus become challenging. Therefore, this study aims to develop composite tubular that possess the comparable mechanical properties to that of blood vessels. The effects of yarn types, tubular knit types, the freeze-thaw cycles of polyvinyl alcohol (PVA), and the drying time of the thawing on the mechanical properties of composite tubular are evaluated in order to assess the implant effectiveness of these composite tubular. Five different wrap yarns are first tested in terms of thermal treatment and twist coefficients, followed by being made into tubular braids, tubular warp knits, and tubular weft knits. Next, PVA hydrogels are combined with the tubular fabrics via casting, after which they are freeze-thawed different cycles with different drying times of thawing. The different composite tubular are evaluated for their mechanical properties. The results indicate that with a thermal treatment temperature of 160 ˚C, the PET/spandex wrap yarn have an elongation that is 86% lower than that of the untreated groups. An increasing thermal treatment temperature results in a decrease in the stress decay and permanent deformation of the PET/spandex wrap yarns. Moreover, an increasing thermal treatment temperature also decreases the shrinkage level of the spandex fibers, and thereby stabilizes the tubular fabrics. The porosity of the tubular fabrics is not dependent on the thermal treatment temperature and yarn types. The tensile strength and elongation of tubular knits are higher than the tensile strength and elongation of the tubular braids. More freeze-thaw cycles lead to a lower compliance, but also a higher bursting strength of vascular grafts, while the combination of spandex fibers improves the compliance of the fabrics and composite tubular. Increasing the drying time for PVA hydrogels is favorable to the compressive strength, bursting strength, and suture retention, while being remarkably adverse to the compliance of the vascular grafts. The warp-knit composite tubular have a higher axial shrinkage when they are circumferentially extended. The weft-knit composite tubular outperform the warp-knit composite tubular in terms of compressive strength, bursting strength and suture retention.

Dissertação de Mestrado Integrado em Engenharia Civil apresentada à Faculdade de Ciências e Tecnologia
A revolução digital está a ganhar espaço em várias indústrias. Mesmo na era da internet e dos robôs, dispositivos sofisticados e simulação em tempo real, o sector da construção continua altamente dependente do trabalho manual. O qual é a principal fonte de atrasos, falta de qualidade e acidentes de trabalho. O desenvolvimento rápido em áreas tecnológicas tais como robôs autónomos, computadores de alta perfomance, sensores, inteligência artificial, gestão de dados e internet das coisas, constitui um enorme potencial para muitas aplicações na indústria da construção. O fabrico aditivo é uma solução interessante, especialmente quando combinada com um sistema subtrativo, pois pode ser aplicada a geometrias complexas e fornece grande flexibilidade na localização e produção. No entanto, as tecnologias existentes, aplicáveis à escala do problema, conduzem a um elevado nível de imperfeições (tensões residuais e distorções) no produto final; as propriedades do material não são suficientemente bem caracterizadas e o comportamento estrutural ou as peças impressas em 3D não estão ainda bem estudadas. Portanto, esta dissertação de mestrado tem como objetivo explorar a aplicação do fabrico aditivo para a produção de elementos metálicos produzidos por fabrico aditivo para a utilização na indústria da construção.Para tanto, realizou-se uma análise numérica e experimental de uma componente produzida através do fabrico aditivo, percorrendo as fases de dimensionamento, fabrico e validação estrutural da peça. O processo utilizado é o cold metal transfer (CMT), que introduz menos calor ao processo de fabrico ao se comparar com os processos tradicionais, reduzindo assim a introdução de tensões residuais e distorções.
The digital revolution is gaining ground in several industries. Even in the age of the internet and robots, sophisticated devices and real-time simulation, the construction industry remains highly dependent on manual work. Which is the main source of delays, lack of quality and work accidents. The rapid development in technological areas such as autonomous robots, high-performance computers, sensors, artificial intelligence, data management and the internet of things, constitutes a huge potential for many applications in the construction industry. Additive manufacturing is an interesting solution, especially when combined with a subtractive system, as it can be applied to complex geometries and offers great flexibility in location and production. However, according to existing technologies, applicable to the scale of the problem, they lead to a high level of imperfections (residual stresses and distortions) in the final product; as material properties are not sufficiently well characterized and the structural behavior or as continuous parts in 3D are not yet well studied. Therefore, this master's thesis aims to explore the application of additive manufacturing for the production of metallic elements produced by additive manufacturing for use in the construction industry.Therefore, a numerical and experimental analysis of a component produced through additive manufacturing was carried out, covering the phases of dimensioning, manufacturing and structural validation of the part. The welding process used is cold metal transfer (CMT), which introduces less heat into the manufacturing process compared to traditional processes, thus reducing the introduction of residual stresses and distortions.
