Texniture, a freestanding functional textile object

ATAPHOL, SUJIRAPINYOKUL January 2011 (has links)
The purpose of this thesis is to explore the possibilities to create freestanding functional textile object that involves thepotential of traditional textile technique for creating three-dimensional textile structures. These three-dimensional textilestructures are used to generate the style of freestanding functional textile object and to create a product for the public room.The subculture and techniques involved in Thai textile techniques are the inspirations throughout this project. Forexample, sitting on the floor is prominent in this subculture and is, therefore; an initiation of the furniture development in thisproject. Meanwhile, Scandinavian design also influences the aesthetic and finds out the simple solution with its simplicityand functionalism. Nature is also a powerful source of inspiration in creating these three-dimensional knitted textiles.These factors influence the method used to explore techniques, colours and style. Moreover, sociology is considered to guidethe design process and to determine the style of freestanding textile object, for instance; the relationships among people.“Texniture” is a name given to the freestanding functional textile object and is a kind of the furniture created in this project. The resultshows how three-dimensional textiles can be manipulated in space, and aims to give audiences a new understanding of textiles.Texniture 1 / Program: Konstnärligt masterprogram i mode- och textildesign

The art of building (Baukunst) of Mies van der Rohe

Kim, Ransoo 12 May 2006 (has links)
This dissertation attempts to interpret the statements of Ludwig Mies vans der Rohe (1886-1969) that pertain to his lifelong theory of Baukunst, or the art of building in terms of tectonics. In order to use the concept tectonics as a criterion according to which one can comprehend Mies words and works, this dissertation attempted to define tectonics in a more general sense by collecting existing definitions and categorizing them. The result of this endeavor showed that tectonics does not signify a supportive structure but the art of framing construction, in which linear elements are put together with joints and clad or infilled with lightweight material. It is proposed that Mies, who called the ideal of tectonic architecture the art of building, during his lifelong career, experienced two periods of critical awareness through which he established his own type of tectonic buildings: awareness of the open plan and then that of clear space. After the former occurred in 1926, he focused on the creation of inner spatial openness; after the latter, which this dissertation proposes occurred around 1930, when he met Karlfried Graf Drckheim (1896-1988), who had been absorbed in Lao-tzus philosophy, Mies intended to show that his architectural concern was beyond physical construction by employing the concept of changing nature and by designing his buildings to be neutral frames. Mies finally achieved a tectonically integrated body of a building that contained extroverted and undetermined space, which he referred to as clear space, or generally called Mies universal space, through his lifelong pursuit for the accomplishment of his own art of building, which this dissertation terms Miesian tectonics.

TIDENS MOTSTÅND En komparativ studie av två skulpturer av Ellen Roosval / THE RESISTANCE OF TIME - A comparative study of two sculptures by Ellen Roosval

Bergström Linder, Carin January 2022 (has links)
This essay is a comparative study of two sculptures with the same motive and name, The Dance. Ellen Roosval created the freestanding sculpture The Dance in 1925 and the relief sculpture The Dance in 1933. The essay has two objectives, an analysis of these works of arts and a spotlight on the artist Ellen Roosval’s as an example of a female artist in the early 20th-century. Her reworking of the sculpture into the relief generates multiple transformations. When analyzing the works of art the aspects of the meaning and reception for the beholder has been crucial. The method theory originates from Wolfgang Kemp and was further developed by Jessica Sjöholm Skrubbe in her thesis. Sjöholm Skrubbe emphasizes on the beholders movements, the meaning of the term site-specific and the impact of the base. Now the questions in the current paper are: how the reception of the works relates to the viewer; how typology, site and material affects the design and expression; and how the works relates to the post-war aesthetics and dance. This also refers to how The Dance:s relates to the post-war aesthetic expressions and the motive. The study starts with a general background on the situation for female sculptors in the early 20th century, the artist Ellen Roosval, and dance. The dance section also introduces the dance company The Swedish Ballet (1920-25) that The Dance:s were tribute to. Then follows a contextualized presentation of the works analyzing formal elements and according to Sjöholm Skrubbe the different sites, the beholders movement and the base. Next, an analysis of typologies, materials and stylistic expressions. After that a deeper analysis focusing on the shaping of the human body, nudity and movements. Roosval’s The Dance 1933 is compared both with the relief The Dance by Antoine Bourdelle from 1912 and the Swedish Ballet performances. The analysis concludes with how site relates to choice of materials and how aesthetics and dance relates to the period 1920s. The results describes aspects of different transformations in relation to the beholders reception. The final discussion concludes on Roosval’s norm-breaker achievements, which inspired the title The Resistance of Time.

<b>BISMUTH-BASED LAYERED SUPERCELL MULTIFERROIC THIN FILMS TOWARDS MULTIFUNCTIONALITY AND DEVICE APPLICATIONS</b>

Jianan Shen (11171664) 02 July 2024 (has links)
<p dir="ltr">Multiferroics, which exhibit multiple ferroic orderings within a single material system, have substantial potential for applications in sensors, transducers, memory devices, and energy harvesters. However, the development of single-phase multiferroics that demonstrate roomtemperature properties remains limited by inherent contradictions in d-orbital occupancy between magnetic and ferroelectric materials. This dissertation focuses on addressing this challenge through the exploration of a novel bismuth-based, single-phase multiferroic thin film that features an exotic layered supercell (LSC) structure and displays multiferroic properties at room temperature. The primary aim is to deepen the understanding of LSC materials and advance their applications in practical devices. The dissertation is structured as follows: It begins with an introduction to the fundamental concepts of multiferroics, including their classifications and applications, the specific characteristics and growth mechanism of LSC materials, and other relevant background knowledge. This is followed by a detailed description of the experimental techniques employed. The core of this dissertation comprises four chapters that present a comprehensive study of LSC materials. The first chapter discusses a nanocomposite system combining an LSC material, Bi1.25AlMnO3.25, with Au nanoparticles (NPs), highlighting its tunable microstructure and multifunctional properties influenced by growth temperature. The second chapter explores the integration of Bi2NiMnO6 on a flexible mica substrate, demonstrating the potential of LSC materials for use in flexible electronics, with performance maintained across various bending conditions. The third chapter details the development of freestanding LSC thin films by utilizing a water-soluble sacrificial layer, which are shown to preserve their microstructure and properties after being transferred onto a silicon substrate. Building on this, the fourth chapter investigates the reuse of recycled SrTiO3 substrates for subsequent thin film growth, examining changes in surface strain states and chemistry to guide sustainable practices in complex oxide thin film processing. In summary, this dissertation presents an extensive examination of LSC multiferroics, revealing their significant promise for multifunctional applications and integration into flexible and silicon-based electronics. Additionally, the work explores sustainable methods for substrate reuse, contributing further to the field of material sciences.<br></p>

Fazendas do sul de Minas: arquitetura rural nos séculos XVIII e XIX / Farms of southern Minas Gerais: rural architecture in the XVIII and XIX centuries

Cruz, Cícero Ferraz 26 September 2008 (has links)
Estuda a arquitetura das fazendas do sul do estado de Minas Gerais nos séculos XVIII e XIX, período marcado pela ruralização e desenvolvimento da agropecuária, pelo deslocamento do eixo econômico da província para a região sul e pela estreita ligação esta região com a corte do Rio de Janeiro. A região delimitada é a porção sul da bacia do Rio Grande, antiga Comarca do Rio das Mortes. São fazendas formadas no período que vai de meados do século XVIII até o fim do século XIX, voltadas à produção de gêneros diversos baseada no trabalho escravo. A metodologia baseia-se no levantamento como fonte primária, na comparação e cruzamento dos dados entre as fazendas, sempre apoiado na bibliografia existente. Conclui que sua arquitetura se caracteriza basicamente pelo uso da mesma técnica construtiva (estrutura independente de madeira e fechamento de pau-a-pique), pelo uso dos mesmos programas de necessidades e pela mesma intenção plástica de tradição clássica, gerando uma família tipológica própria dentro do panorama da arquitetura nacional. / This study is about rural farm architecture constructed in the eighteenth and nineteenth centuries in the southern region of the state of Minas Gerais (General Mines). This time period is characterized by ruralizaton, economic and social isolation, and a continued link to Colonial Rio de Janeiro. Geographically, this particular region of Brazil is part of the Rio Grande river basin, formerly the Rio das Mortes. The farms studied are farms that were developed beginning in the mid nineteenth century until the end of the 19th century, following the abolition of slavery. The methodology is grounded in the survey as a primary aspect and in the comparison and intersection of the researched facts between farm structures, always supported by existing studies. I concluded that the architecture of this period of time is characterized by the use of common construction methods (a freestanding wood structure sheathed in wattle and daub), by similar programs of necessities and by the same material intention of the classic tradition, generating a specific typology within the larger panorama of Brazilian national architecture.

FABRICATION OF MAGNETIC TWO-DIMENSIONAL AND THREE-DIMENSIONAL MICROSTRUCTURES FOR MICROFLUIDICS AND MICROROBOTICS APPLICATIONS

Li, Hui 01 January 2014 (has links)
Micro-electro-mechanical systems (MEMS) technology has had an increasing impact on industry and our society. A wide range of MEMS devices are used in every aspects of our life, from microaccelerators and microgyroscopes to microscale drug-delivery systems. The increasing complexity of microsystems demands diverse microfabrication methods and actuation strategies to realize. Currently, it is challenging for existing microfabrication methods—particularly 3D microfabrication methods—to integrate multiple materials into the same component. This is a particular challenge for some applications, such as microrobotics and microfluidics, where integration of magnetically-responsive materials would be beneficial, because it enables contact-free actuation. In addition, most existing microfabrication methods can only fabricate flat, layered geometries; the few that can fabricate real 3D microstructures are not cost efficient and cannot realize mass production. This dissertation explores two solutions to these microfabrication problems: first, a method for integrating magnetically responsive regions into microstructures using photolithography, and second, a method for creating three-dimensional freestanding microstructures using a modified micromolding technique. The first method is a facile method of producing inexpensive freestanding photopatternable polymer micromagnets composed NdFeB microparticles dispersed in SU-8 photoresist. The microfabrication process is capable of fabricating polymer micromagnets with 3 µm feature resolution and greater than 10:1 aspect ratio. This method was used to demonstrate the creation of freestanding microrobots with an encapsulated magnetic core. A magnetic control system was developed and the magnetic microrobots were moved along a desired path at an average speed of 1.7 mm/s in a fluid environment under the presence of external magnetic field. A microfabrication process using aligned mask micromolding and soft lithography was also developed for creating freestanding microstructures with true 3D geometry. Characterization of this method and resolution limits were demonstrated. The combination of these two microfabrication methods has great potential for integrating several material types into one microstructure for a variety of applications.
