Broadband scanning arrays require small element spacing over a broad frequency band to achieve the desired scan capabilities. Previous research has concentrated on the development of small broadband elements to meet the demands of broadband arrays. However, mutual coupling between elements in a tightly spaced array can change the operating frequency and bandwidth from that of the single isolated element. Several research efforts have focused on minimizing the mutual coupling to maintain the frequency response of the single isolated element. This dissertation focuses on using the strong coupling between Foursquare antennas to obtain the broadband frequency response while maintaining a small element spacing. The isolated Foursquare antenna was modeled using an in-house FDTD code. The modeled current distribution over the frequency band of operation revealed how the antenna achieved a broadband frequency response. Because of this understanding of the single element, the downward shift in the frequency response of the Foursquare antenna in a fully active array could be anticipated. Furthermore, the infinite array models of the Foursquare revealed an increase in bandwidth. Both are desirable characteristics for a broadband scanning array. Therefore, through this research using the Foursquare element, it has been shown that the strong mutual coupling in a tightly spaced array can have advantages if initially taken into consideration when designing the array. / Ph.

Como elemento embutido em sistemas sociais, econômicos e culturais, o software interfere na maneira como os indivíduos se relacionam entre si, consigo próprios e com o meio à sua volta. Nesse sentido, a computação ubíqua tem desafiado a pesquisa em tecnologias da comunicação a repensar muitas das tradicionais definições na área – a começar pela própria mídia. Os atuais programas computacionais de criação e edição de conteúdo propiciam a hibridização entre distintos formatos, linguagens e estéticas, originando novas espécies midiáticas. Também têm se tornado cada vez mais fluidas, ou mesmo inexistentes, as fronteiras entre usuário e produtor de conteúdo, homens e máquinas, espaço “físico” e dimensão “virtual”. Além disso, as possibilidades de expansão sensório-cognitiva abertas pelas novas tecnologias de informação e comunicação têm instigado o questionamento do próprio conceito de “ser humano”. Este trabalho discute algumas das transformações sociais provocadas pela computação ubíqua, a partir da perspectiva dos software studies. O aplicativo para smartphones Foursquare foi objeto de estudo empírico, feito a partir de entrevistas com usuários do serviço. Na abordagem, foram discutidas questões como exploração do espaço físico a partir de dispositivos móveis de comunicação, interação entre usuários, recomendações publicadas na rede e gamificação. Os resultados apontam para um cenário no qual as pessoas não apenas elegem quais mídias consumir, mas personalizam o uso das ferramentas disponíveis, de forma a conferir-lhe utilidade única e individualizada. / Information technology is present in many different areas of contemporary life. As embedded part of social, economic and cultural systems, software influences the way people interact with each other and with the environment. Ubiquitous computing has challenged the research in communication technologies to rethink many of the traditional definitions in the area. Computer programs for content creating and editing provide the hybridization between different formats, languages and aesthetics, what engenders new media species. The boundaries between user and producer of content, men and machines, 'physical' space and "virtual" dimension have also become increasingly fluid, or even nonexistent. Furthermore, the possibilities of sensory-cognitive expansion offered by communication technologies have led researchers to question even the concept of "human being." This work discusses some of the social changes brought about by ubiquitous computing, from the perspective of software studies. The application for smartphones Foursquare was the subject of an empirical study, done from interviews with its users. In the approach, issues such as space exploration from mobile communication devices, interaction between users, recommendations on the internet and gamification were discussed. The results point to a reality in which people not only choose which kinds of media they want to consume, but customize the use of the tools available, in order to give them an unique and personalized utility.

This thesis brings forth the regional architecture of New Orleans, Louisiana, and applies it directly towards the reconstruction and reconstitution of the Lafitte Housing Project closed as a result of Hurricane Katrina in late August 2005. The half-mile long Lafitte Housing Project rests just outside the French Quarter in the Sixth Ward. This thesis proposes reopening the canal along Jefferson Davis Parkway and extending it into the French Quarter to the southern edge of Louis Armstrong Park. As many of the former apartments were damaged by flooding from Hurricane Katrina, some units will be demolished to make way for site changes. A problematic condition of the former public housing complex was the way that it stood within the site as a massive homogenous entity, far out of scale to the surrounding urban fabric. The solution to rebuilding the site is not to construct another massive housing community. Rather, this proposal would include restoring many of the existing units, providing a historic anchor to the new neighborhood, and allowing them to remain along with new construction. Earth removed from the canal will stay on the site and be used to construct a half-mile long mound, running most of the length of the projects. This mounded area will feature spaces for recreational activities, Marti Gras celebrations, relaxation, and it will allow bridged access to the second floors of the new buildings. More important than what the mound does, is what it is: a metaphor for rising up from the mud and water and towards an elevated way of living, for inhabitants of the new and old structures. The vehicle for the form and structure of the new dwelling units is the historic Foursquare house. A house that symbolizes aristocracy and well-being, these new units are a refinement of the two bedroom apartments in the existing public housing complex. In this proposal, both will coexist throughout the site. / Master of Architecture

This thesis explores new mobile media sharing applications by building, deploying, and studying their use. While we share media in many different ways both on the web and on mobile phones, there are few ways of sharing media with people physically near us. Studied were three designed and built systems: Push!Music, Columbus, and Portrait Catalog, as well as a fourth commercially available system – Foursquare. This thesis offers four contributions: First, it explores the design space of co-present media sharing of four test systems. Second, through user studies of these systems it reports on how these come to be used. Third, it explores new ways of conducting trials as the technical mobile landscape has changed. Last, we look at how the technical solutions demonstrate different lines of thinking from how similar solutions might look today. Through a Human-Computer Interaction methodology of design, build, and study, we look at systems through the eyes of embodied interaction and examine how the systems come to be in use. Using Goffman’s understanding of social order, we see how these mobile media sharing systems allow people to actively present themselves through these media. In turn, using McLuhan’s way of understanding media, we reflect on how these new systems enable a new type of medium distinct from the web centric media, and how this relates directly to mobility. While media sharing is something that takes place everywhere in western society, it is still tied to the way media is shared through computers. Although often mobile, they do not consider the mobile settings. The systems in this thesis treat mobility as an opportunity for design. It is still left to see how this mobile media sharing will come to present itself in people’s everyday life, and when it does, how we will come to understand it and how it will transform society as a medium distinct from those before. This thesis gives a glimpse at what this future will look like. / <p>At the  time of doctoral defense, the following paper was unpublished and had a status as follows: Paper 4: Submitted.</p> / Mobile Life Centre
