An SVD processor system is presented in which each processing element is implemented using a simple CORDIC unit. The internal recursive loop within the CORDIC module is exploited, with pipelining being used to multiplex the two independent micro-rotations onto a single CORDIC processor. This leads to a high performance and efficient hardware architecture. In addition, a novel method for scale factor correction is presented which only need be applied once at the end of the computation. This also reduces the computation time. The net result is an SVD architecture based on a conventional CORDIC approach, which combines high performance with high silicon area efficiency.

Double Skin Façades (DSFs) are becoming increasingly popular architecture for commercial office buildings. Although DSFs are widely accepted to have the capacity to offer significant passive benefits and enable low energy building performance, there remains a paucity of knowledge with regard to their operation. Identification of the most determinant architectural parameters of DSFs is the focus of ongoing research. This paper presents an experimental and simulation study of a DSF installed on a commercial building in Dublin, Ireland. The DSF is south facing and acts to buffer the building from winter heat losses, but risks enhancing over-heating on sunny days. The façade is extensively monitored during winter months. Computational Fluid Dynamic (CFD) models are used to simulate the convective operation of the DSF. This research concludes DSFs as suited for passive, low energy architecture in temperature climates such as Ireland but identifies issues requiring attention in DSF design.

Libertarian paternalism, as advanced by Cass Sunstein, is seriously flawed, but not primarily for the reasons that most commentators suggest. Libertarian paternalism and its attendant regulatory implications are too libertarian, not too paternalistic, and as a result are in considerable tension with ‘thick’ conceptions of human dignity. We make four arguments. The first is that there is no justification for a presumption in favor of nudging as a default regulatory strategy, as Sunstein asserts. It is ordinarily less effective than mandates; such mandates rarely offend personal autonomy; and the central reliance on cognitive failures in the nudging program is more likely to offend human dignity than the mandates it seeks to replace. Secondly, we argue that nudging as a regulatory strategy fits both overtly and covertly, often insidiously, into a more general libertarian program of political economy. Thirdly, while we are on the whole more concerned to reject the libertarian than the paternalistic elements of this philosophy, Sunstein’s work, both in Why Nudge?, and earlier, fails to appreciate how nudging may be manipulative if not designed with more care than he acknowledges. Lastly, because of these characteristics, nudging might even be subject to legal challenges that would give us the worst of all possible regulatory worlds: a weak regulatory intervention that is liable to be challenged in the courts by well-resourced interest groups. In such a scenario, and contrary to the ‘common sense’ ethos contended for in Why Nudge?, nudges might not even clear the excessively low bar of doing something rather than nothing. Those seeking to pursue progressive politics, under law, should reject nudging in favor of regulation that is more congruent with principles of legality, more transparent, more effective, more democratic, and allows us more fully to act as moral agents. Such a system may have a place for (some) nudging, but not one that departs significantly from how labeling, warnings and the like already function, and nothing that compares with Sunstein’s apparent ambitions for his new movement.

A presente tese de doutoramento procura focar o vidro como material plástico para a concepção de obras de arte. Os seus alicerces caracterizam-se pelo estudo técnico sobre o uso do vidro e a sua aplicação na realização de obras com pressupostos estéticos e artsticos. Hoje a arte em vidro apresenta-se inovadora e contemporânea, procurando uma componente ligada à pesquisa e à experimentação. Portugal possui uma ampla história ligada à tradição do vidro, em especial ao vitral. No que concerne à sua aplicação na arte contemporânea, assistimos a um renovado interesse por parte de vários artistas. No entanto, quando se trabalha com o vidro, é necessário o artista conhecer e dominar a técnica que utiliza, para assim compreender as potencialidades que o material oferece e empregá-las de acordo com o seu modus operandi. Cria-se uma relação entre a ciência e a arte, uma descoberta e utilização de novos conhecimentos, em que se pretende manter uma relação estreita entre o cientista e o artista através do desenvolvimento de novos materiais, nomeadamente os vidros e esmaltes luminescentes e a adição de óxidos de metais de transição 3d na sua composição. Neste sentido foram desenvolvidos estudos minuciosos sobre a técnica de kilncasting onde se utilizou o vidro sonoro superior produzido no CRISFORM (Centro de Formação Profissional para o Sector da Cristalaria), na Marinha Grande. Assim, verifica-se que as premissas desta tese podem ser divididas em três vertentes: a) Uma contextualização histórica e teórica do panorama artstico do vidro em Portugal; b) Uma componente teórica/prática do estudo do vidro: a ciência do vidro, a sua composição, com a preocupação de utilizar esses conhecimentos para a elaboração de amostras práticas, onde a componente técnica é fundamental para a produção de futuras obras de arte; c) A idealização de obras de arte e a utilização do vidro como material plástico para a sua realização. Na elaboração destas obras procurou-se focar a dicotomia entre transparência versus opacidade, os efeitos cromáticos produzidos por diferentes espessuras e texturas do vidro, assim como da monocromia versus policromia, esta última através do vidro e esmaltes luminescentes. Em suma, na complementaridade laboratório/ateliê, os segredos da matéria abrem novas fronteiras à criatividade estética.

Este doutoramento em Estudos de Arte centra-se no artista plástico, em Portugal, hoje. De acordo com o seu carácter projectual, estrutura-se em dois vectores distintos, ainda que relacionados entre si e devedores um do outro: -Um corpo prático, assente na prática artstica de atelier e dando continuidade ao percurso artstico autoral próprio (conducente à série de imagens fotográficas “Prática Artstica Enquanto Ferramenta de Higiene Pessoal”); -Um eixo reflexivo, construído a partir da análise qualitativa do conteúdo de um conjunto de entrevistas presenciais realizadas a artistas plásticos portugueses (conducente ao manifesto artstico “O Artista pelo Artista”). Neste sentido, este estudo vai ao encontro de vinte e seis artistas plásticos contemporâneos portugueses reunidos numa amostra seleccionada pelo crítico de arte Miguel von Hafe Pérez. A saber: Alberto Carneiro, André Cepeda, André Gonçalves, Ângela Ferreira, António Olaio, Carla Cruz, Carla Filipe, Cristina Mateus, Daniel Blaufuks, Eduardo Batarda, Fernando José Pereira, Francisco Queirós, Gerardo Burmester, Joana Vasconcelos, João Pedro Vale, João Tabarra, José de Guimarães, Mafalda Santos, Marta de Menezes, Miguel Leal, Miguel Palma, Paulo Mendes, Pedro Calapez, Pedro Proença, Rui Chafes e Zulmiro de Carvalho. O documento que reúne o conjunto das entrevistas realizadas, anexo a esta investigação, distancia-se do discurso utilizado nas retóricas das narrativas históricas, teóricas ou críticas. Aqui, procuram-se as palavras dos criadores, sem mais. Decorrente do percurso metodológico que orientou a análise qualitativa do conteúdo, este estudo propõe o manifesto artstico "O Artista pelo Artista" enquanto resultado do exercício de investigação. Ainda, este trabalho apresenta a série de imagens fotográficas “Prática Artstica Enquanto Ferramenta de Higiene Pessoal” como projecto-tese centrado no movimento que guiou todo o processo investigativo: da reflexão sobre o outro (e sobre as suas palavras) para a reflexão sobre o próprio (e sobre a sua intimidade). Através das vinte e seis entrevistas, do manifesto “O Artista pelo Artista” e da série de imagens “Prática Artstica Enquanto Ferramenta de Higiene Pessoal”, esta investigação devolve a palavra aos próprios artistas, a todos os outros operadores da esfera artstica e ao público interessado em conhecer o criador apresentado por si próprio, sem mediadores, num acto sincero, franco e generoso.

Nomadic Narratives, Visual Forces explores issues, questions, and problems emerging in the analysis of epistolary and visual narratives. This book focuses in particular on Gwen John's letters and paintings. It offers an innovative theoretical approach to narrative analysis by drawing on Foucault's theory of power, Deleuze and Guattari's analytics of desire, and Cavarero's concept of the narratable self. Furthermore, it examines the use of letters as documents of life in narrative research and highlights the dynamics of spatiality in the constitution of the female self in art. This study brings together theoretical insights that emerge from the analysis of life documents - some of them previously unpublished - combining innovative research with specific methodological suggestions on doing narrative analysis.

The chapter critiques the rise of participation in art since the 1990s – a development that sees artists and curators searching continually for new and increased levels of audience inclusion. While there has been much discussion about what might be gained by participating in an artwork, we ask what might be lost by this act. We also question the extent to which participation is a useful social or aesthetic strategy in circumstances where it remains bound by the institutional structures of the artworld. For this reason, our work is an attempt to transform the broader ‘apparatus of art and to create works in which the roles assigned to individuals and groups remain fluid and subject to continuous negotiation. As a means of an attempt at resisting absorption into the institutional structures of the artworld, we privilege a form of participation that remains immanent in the work, but that never crystallizes into a single or definable role. Kathryn Brown , art historian and editor of Interactive Contemporary Art, says, ‘It is, perhaps, a fitting end to the discussions of the present volume that the most interesting and valuable form of participation envisaged by Freee is one that must remain impossible.’

E-poltergeist takes over the user’s internet browser, automatically initiating Web searches without their permission. Web-based artwork which explores issues of user control when confronted with complex technological systems, questioning the limits of digital interactive arts as consensual reciprocal systems. e-poltergeist was a major web commission that marked an early stage of research in a larger enquiry by Craighead and Thomson into the relationship between live virtual data, global communications networks and instruction-based art, exploring how such systems can be re-contextualised within gallery environments. e-poltergeist presented the 'viewer' with a singular narrative by using live internet search-engine data that aimed to create a perpetual and virtually unstoppable cycle of search engine results, banner ads and moving windows as an interruption into the normal use of an internet browser. The work also addressed the ‘de-personalisation’ of internet use by sending a series of messages from the live search engine data that seemed to address the user directly: 'Is anyone there?'; 'Can anyone hear me?', 'Please help me!'; 'Nobody cares!' e-poltergeist makes a significant contribution to the taxonomy of new media art by dealing with the way that new media art can re-address notions of existing traditions in art such as appropriation and manipulation, instruction-based art and conceptual art. e-poltergeist was commissioned ($12,000) for 010101: Art in Technological Times, a landmark international exhibition presented by the San Francisco Museum of Modern Art, which bought together leading international practitioners working with emergent technologies, including Tatsuo Miyajima, Janet Cardiff, Brian Eno.
