Spaces of male prostitution : tactics, performativity and gay identities in streets, Go-Go bars and magazines in contemporary Bangkok, Thailand

Suwatcharapinun, Sant 2005 (has links)
This research explores the spatial practices of male prostitutes meeting gay male clients in various urban environments in Bangkok, Thailand. The research focuses on the male prostitutes’ spatial practices in three meeting places: the streets around Saranrom park, the gay go-go bars in Surawong’s Boys’ Town, and the representations of space in local gay newsletters. Examining the male prostitutes’ spatial practices through ‘tactics’, this research suggests that male prostitutes use the meeting places differently as ways of responding to the ‘strategies’ of gay male clients. This research also suggests that the tactics of male prostitutes can be examined by exploring the relationship between spatial practices and subjectivities. By exploring how specific performative acts constitute male prostitutes’ subjectivities, this research suggests that male prostitutes ‘perform’ homosexuality. This thesis draws upon Judith Butler’s performativity theory as a discursive mode of constituting subjects and Michel de Certeau’s theoretical discussion, specifically spatial practices of ‘strategies’ and ‘tactics’, as a means of differentiating between ‘place’ and ‘space’. Methodologically, this research works in two directions: the first explores how the spatial practices of male prostitution produce ‘gay’ subjectivities in the moment of sexual encounter – arguing that male prostitutes actively reposition themselves as ‘subjects’ rather than ‘objects’ through spatial and sexual practices; and the second examines the social and sexual constitution of space – arguing that ‘places’ are produced as ‘spaces’ through the practices and tactics of male prostitutes. This research aims to make an original contribution to knowledge in four main ways. The first is an exploration of the relationship between de Certeau’s spatial theory of ‘tactics’ and Butler’s concept of ‘performativity’ as a constitution of subjectivity. The second is the use of de Certeau and Butler’s theories to explore three spaces of male prostitution in contemporary Bangkok, Thailand, through observations drawn from interviews, accounts of spatial experience, and discussions of various representations of space. The third is a reconsideration of these theories of performativity and spatial practices in the light of the specific conditions of the case studies in Bangkok. The fourth is the production of new forms of cross-disciplinary knowledge to bring this discussion of tactics, performativity and gay subjectivities in streets, go-go bars and magazines into architectural history and theory, thereby producing new ways of understanding how spaces are produced through encounters and looks.

Groundplay

Tekle, Nebiyou 30 August 2004 (has links)
Children go about their playful desires, in their immediate environments spontaneously. Learning to look, touch, hear, and feel are the primary objectives of these early lessons in the playground, and it is a skill that is associated with all future learning and one that can last a lifetime. Playgrounds also offer a developmentally appropriate environment in which children are given opportunities to make choices, pursue their own questions and concerns, connect what is known to the unknown, and be successful as they explore and discover through play, informal learning activities, and projects.

Translation From Image to Building

Zhu, Anqing 2012 (has links)
After the fire accident, KTH school of architecture is no longer in its best performance. The school indeed need an extension. However, through out this thesis project, I attempt to take one step further. It is not only to construct a functional school, but reconsider the meaning of architectural education. I am interested in three aspects, which all of them has being driving forces to this project. Firstly, I was interested in memory of the old architecture school in Stockholm, which was accommodated in a 19th centry wooden building. It was old and small, but students loved it. One’s memory of certain places would shape his thinking and values as an architect. Therefore, my design attempts to bring back such a memory by study some of the details in the old building and bring them back into the new extension with a twist. Secondly, in terms of working method I am very much resisted to ‘Graphic Architecture’, models always come together with rending images. They are offered to read side by side. The rending images are not trying to present the final products but also used as a development tool. Overall this project was developed from the inside towards the outside. The aim was to make an ordinary building with some thoughtful touches.

Grid + Ghost

Neufeld, Stephanie 2013 (has links)
The thesis begins with a notion to design a school of architecture in Saskatchewan. The context, at first, appears overwhelmingly basic: an agricultural grid superimposed on a horizontal plain, under an endless sky. This formulaic description cannot capture what it is to experience the place. Stemming from this archetypal divide between earth and sky, the character of the prairies develops through a series of pairs. Each four-part section begins by setting up a polarity; on one side, a grid, and on the other, a ghost. The intersection of these two elements is illustrated through an interface and a segment of time. With each added layer, the polarities become increasingly entwined. The school of architecture is located, conceptually, in this space of reciprocity. The physical site is an industrial wasteland near the centre of Saskatoon, bounded on the east and west sides by two sets of train tracks. A timber and masonry warehouse, constructed for the John Deere Plow Company in 1910, is located along the end of the spur line to the east. The school of architecture finds itself within this building. The view down the tracks provides a glimpse of the prairie fields; the nondescript site itself alludes to this Deleuzian smooth space beyond the city limits. Even as it precisely situates and contains itself in this physical urban context, the school of architecture internalizes the dream of the prairie landscape. It is an educational institution and an incubator for the architectural imagination.

A Study on Microstructures of Homogenization for Topology Optimization

Wang, Yulu 2003 (has links) (PDF)
This thesis studies topology optimization method employing the homogenization method, with a focus on different microstructures and their effects on the topology optimization solutions. In the thesis, different microstructure models were investigated. The strengths and weaknesses of each type of microstructures were discussed. Homogenization method was employed to formulate the homogenized properties of the material. The optimality criteria and schemes of updating the design variables in the topology optimization process were derived for the newly developed microstructures and existing microstructures for which the information is not available in the literature. New microstructure models of one-material and bi-material were established. Based on these studies, a computer software package called Homogenization with Different Microstructures (HDM) incorporating fifteen existing and the new microstructure models was developed. By using the software, a series of problems were studied and solutions given by different microstructure models were compared.

A Study of Air Flow Effects on the Cushioning Characteristics of Multi Layered Pre-Compressed Fibreboard

Minett, Mervyn W 2006 (has links) (PDF)
Multi-layered corrugated fibreboard, has in recent years been gaining attention as a replacement for polymeric materials for protective packaging for environmental reasons. The properties of pre-compressed multi-layered corrugated fibreboard make it a sustainable replacement for poly-foam and polystyrene. Pre-compressed multilayered fibreboard cushions have most of the structural resistance and damping removed, and the properties of air-flow through the flutes becomes a more predominant, they behave more like a soft spring. Artificially restricting the exiting airflow or prudently choosing the direction of flutes in the case of rectangular cushions, allows for the differing design situations that may be required. A mathematical model is developed, to describe the pre-compressing process. Mathematical models and software are developed, based on the airflow characteristics, that allow for the prediction of peak acceleration for differing end conditions or sizes providing the friction component can be estimated using iterative methods. The models were verified by a static compression test for the pre-compression and by dropping a mass, or platen and recording the resistive acceleration, or dynamic behaviour, over a time range. There exists an acceleration component prior to platen contact, which is also modelled and should be considered in the interpretation of test results. The study has presented three models to allow for the prediction of the behaviour of multi-layered corrugated fibreboard for the use as protective cushions. The main thrust has been the behaviour of the airflow during and prior to impact whilst testing. The models developed will assist in the design of protective packaging and produce predictive tools for the use in the packaging industry.

An Investigation of Electro-Rheological Fluids in Engineering

Truong, Tam Dinh 2006 (has links) (PDF)
The essential characteristic of controllable fluids is their ability to change their rheological behaviour under an electrical field. These materials are referred as Electro-Rheological (ER) fluids. An ER fluid is a mixture of a base fluid, usually some type insulating liquid such as mineral or silicone oil, with suspension particles, such as cornstarch, zeolite, glass bead or cellulose. When there is no electric field, particles are randomly suspended in the base liquid. When an electric field is applied, the particles in the fluid form chains bridging the conductors of opposite polarity and turn the liquid into a solid-like gel. The process is seemingly reversible once the electric field is removed. The process takes place within milliseconds. In this thesis, shear and valve modes of operation are considered for one particular ER fluid from a practically oriented design point of view. Chapter 1 provides background information concerning ER fluids and ER devices in practical applications. Chapter 2 describes a prediction tool for the shear mode of operation based on the Bingham model. The prediction model is based on the (solid to liquid) weight fraction, applied electric field and strain rate. An ER clutch with a single disk was designed, and tested to validate the model. In Chapter 3, an ER valve experiment is presented to relate the force-displacement behaviour with varying applied voltage, weight fraction and other operating conditions (volume flow rate, cyclic frequency and stroke length). A new model for an ER damper in fluctuating flow is also presented in Chapter 4. This new model is a modification of the uniform flow Bingham plastic model. Comparison between the predictions from the model and observations from the experiments is also given in Chapter 4. In Chapter 5, an overview is given of this work’s contribution and future work is discussed.

A Study of Wireless Modem Performance Using Multiple Element Antennas

Lebrun, Guillaume 2004 (has links) (PDF)
Next generation wireless modems are likely to be based on multiple antenna hardware platforms, following the demand for high data rate. In correlated channels Channel State Information (CSI) at the transmitter provides a significant capacity increase over conventional Multiple Input Multiple Output (MIMO) systems. In such a case, the Singular Value Decomposition (SVD) of the channel matrix gives the optimal precoder and decoder. This thesis studies the performance of the SVD architecture under varying propagation environments, as well as its robustness to various impairments, e.g. incorrect channel estimation, hardware errors. The aim is to provide a comprehensive understanding of the advantages and weaknesses of the SVD-based transmission architecture.
