Each stitch is a piece of me that I give, a moment of my life and a unit of my love, meticulously culminated into a universal visual language. The optimist in me knits for the cause, while my formalist counterpart works to make the images that sell my thoughts. I knit for the lovers.I make these objects as a practice and a confirmation of my optimism. I make these images to communicate and persuade as a serious contender while at the same time retaining my own optimism and sanity by promising to never take myself too seriously.

I have gained control over a whole space through the use of video projections, soundscaping and various other materials including some interactive media, enabling me to give the audience a fuller sensual experience. Multi‐media has made it possible for artists such as myself to create artworks that require more than a visual conversation with the viewer. The manipulation of memory by time became a physical manifestation in the environments that I create with the use of multi‐media installations.

Subsea pipelines are used extensively throughout the world’s oceans to transport oil and gas from offshore facilities to land, often hundreds of miles. These pipelines range in diameter from three to sixty inches and are installed in deeper depths every year, currently as deep as 2,900 meters. Pipeline construction and installation costs are a large percentage of offshore projects and thus, methods toward reducing costs is an imperative objective. With pipeline installation projects taking place in harsher environments, vessel operability is vital. This work presents an improved method for determining limiting criteria for pipelay operations to more effectively plan and execute offshore projects. This improvement is based on the consideration of total effective pipeline stresses as the limiting criterion rather than the traditionally used limiting pitch angle. Limiting sea curves based on a sample dynamic pipeline analysis are shown and their incorporation in workability planning is discussed.

O mercado de construção civil e montagem eletromecânica brasileiro vêm ganhando força com a instalação e ampliação de diversos parques industriais no país. O restabelecimento dos investimentos na área faz com que as empresas especializadas e grandes empreiteiras voltem a investir no mercado industrial, porém, tamanho investimento e exigência dos clientes privados fazem com que as montadoras e empreiteiras estejam cada vez mais especializadas no planejamento e execução de seus serviços, aumentando assim, cada vez mais a competitividade entre as mesmas. Na etapa de orçamento dos serviços, a melhor estimativa de um determinado serviço de Instalações Elétricas Industriais (IEI) é aquela que consegue representar com o maior grau de confiabilidade todos os requisitos necessários para a realização de uma determinada atividade. O objetivo deste estudo é definir uma metodologia para a determinação dos índices de produtividade mais adequados para o orçamento de instalações elétricas industriais e residenciais, resultando em maior segurança para a empreiteira na realização do serviço e informações mais seguras para planejamento e negociação. / The Brazilian market for civil construction and electromechanical assembly has been increasing with the creation and expansion of several industrial parks in the country. The growth of investments in these areas is encouraging specialized and construction companies to focus again on the industrial market. Besides this, all the investments and requirements made by private companies have forced construction companies to develop more sophisticated planning and execution methods, leading to high competitiveness between them. Regarding the budget, a realistic estimative of a certain Industrial Electrical Installation (IEI) usually represents, with more reliability, all the requirements needed to accomplish a particular activity. The purpose of this assay is to define a methodology to determine the most adequate productivity factors as regards to residential and industrial electrical installations budget. Reliable information will help construction companies during the planning, negotiation and accomplishment phases.

A aproximação com a paisagem é determinada pela articulação dos trabalhos com o lugar, que instiga a reflexão sobre a experiência espacial do observador. Do ponto de vista da artista, o texto aponta para os meios e suportes adotados e desenvolve relações específicas entre obra, espaço físico e imaginação. / This study presents my artistic production between the years of 2005and 2007, as well as the poetical and theoretical questions involvedin this works: installed images in several places. The proximity withthe landscape is determined by the articulations of the work with theplace, instigating the reflection about the spatial experience of theobserver. From the artist´s point of view, the text poitns to themediums and suports that are adopted, developing specific relations between the work, phisical space and imagination.

Esta pesquisa compreende uma reflexão teórica e uma produção em artes que pensa a complexidade do olhar e os fluxos do corpo do espectador dentro do museu. Busca compreender os dispositivos que determinam o movimento e o comportamento do público nos espaços expositivos e estabelece um diálogo com obras de outros artistas que também têm o museu como questão. O processo de construção da obra parte de um arquivo pessoal com imagens, registros sonoros e outros materiais coletados em museus. A pesquisa se desdobra na instalação Vértices|Vetores, proposta ao Espaço das Artes da USP. Essa obra ressignifica imagens e sons apropriados desse arquivo, articulados com projeção de luz. A dissertação assume o formato de um livro de artista, uma caixa-arquivo composta de cinco cadernos, nos quais se articulam reflexões teóricas, anotações do processo e uma leitura da obra. Parte da pesquisa é também compartilhada na seção \"Rede\" da plataforma on-line do Fórum Permanente. / This research comprises a theorical reflection and production in arts that looks up to the complexity of the sight and the expectator\'s body flows inside the museum. It aims to understand the \'dispositifs\' that determines the public\'s movement and behavior in the exhibition spaces and sets a dialogue with other artists\' work which also have the museum as a matter. The process of the work construction starts with a personal archive with images, sound records, among other materials collected in the museum. The research develops into the Vertices/ Vectors, proposed to the arts space at USP. This work reinforces images and sounds appropriated from this archive, articulated with light projection. The dissertation is set up like an artist\'s book, a file-box composed by five brochures, in which theoretical reflections, process notes and a commentary about the work are articulated. Part of the research is also shared on the section \"Rede\" of the on-line platform of the Fórum Permanente.

Syftet med denna forskning genom design och kvalitativa undersökning är att skapa en audiovisuell installation vilket mäts av en fokusgrupp för att se om fenomenet Immersion uppnås hos informanterna. Det är informanternas kollektiva och subjektiva upplevelse av installationen som ligger till grund för studiens resultat och berör frågor inom det audiovisuella området. Installationen undersöks i förhållande till rummet den tar plats i som en viktigt påverkande aspekt. Studien ska ses på som ett förslag för hur fenomenet Immersion kan uppnås genom audiovisuella verktyg. Alltså är detta en studie som inte försöker nå en absolut sanning genom undersökningen utan olika resultat kan nås även om genomförandet av installationen skulle försökas återskapas. Resultaten tyder på att Installationen kändes Immersiv och nåddes genom projektionskonstformen och spatialt 3D ljud. Samt att andra aspekter och egenskaper som att installationens fysiska form, vilket bestod av genomskinligt tyg som omringade informanterna, påverkade deras Immersion positivt genom att avskärma deras perception. Det presenteras även andra aspekter och egenskaper som påverkade informanternas upplevelse av Immersion positivt men även resultat som påverkade upplevelsen negativt, vilket är lika viktigt för vidare forskning och som bidrag till det kunskapsområdet. Styrkan i undersökningen är presentationen av installationens genomförande men framförallt resultatet som bidrar med förståelse och perspektiv till ett svårformulerat intresseområde. Svagheten ligger i och med att fokusgruppdiskussioner och kvalitativa underökningar inte går att generaliseras, samt så är validiteten svår att styrka. Ytterligare en svaghet är att bara en fokusgrupp användes för studiens undersökning vilket gör det svårt att säkerställa resultatets giltighet.

This thesis aims to explore the temporal and material limits of architectural drawing through the question of urban representation. Challenges posed by the latter are used to put pressure on the fixity of drawing conventions, in order to expand architectural drawing’s range of concerns to the transitory conditions of space that emerge between order and event. Since the eighteenth century, the city has acted as the ground and mirror of the productive, economic, social and epistemological breaks and turns that have marked the passage to modernity. This radical transformation of the city and its modes of experience and inhabitation, combined with the visual culture that has since emerged, have raised questions of presence and representation with regards to both the city and its image in architectural drawing. This thesis aims to bring these questions into the frame of the current concerns in architectural representation, following the deconstructive and cartographic approaches that emerged in the latter half of the twentieth century and the effects of a rising virtuality. As the understanding of space has shifted from the idea of an a priori extensity of vacuum versus matter to a dynamic multiplicity of relations, respectively architectural representation is understood as itself a transaction: a complex oscillation between the real and the mental. This research becomes concerned with exploring drawing as a situated experience that involves the inhabitation of both the space of the city and the drawing. Such a consideration of drawing as a distinct spatiality consequently brings to the fore a dynamic and productive reciprocity between the city and its representation. In order to engage with the intangible projective spatiality of drawing and the negotiations that take place in the movement of representation, the thesis examines the processes involved in the representation of the urban through the immersive site-specificity of installation. Installation is proposed as a way of drawing in space, and thus of foregrounding the question of the space of drawing. The thesis unfolds as a movement across the space of drawing, through a series of essays and corresponding installations which cumulatively form a survey of a city, while performing a close inquiry into the agency of the distinct elements of drawing. Edinburgh serves as both the object and the place of performance, the testing ground, for this act of observation and representation.

As computer networks evolve, they become more complex, introducing several challenges in the areas of performance and management. Such problems can lead to stagnation in network innovation. Software Defined Networks (SDN) framework could be one of the best candidates for improving and revolutionising networking by giving the full control to the network administrators to implement new management and performance optimisation techniques. This thesis examines performance issues faced in SDN due to the introduction of the SDN Controller. These issues include the extra delay due to the round-trip time between the switch and the controller as well as the fact that some packets arrive at the destination out-of-order. We propose a novel dynamic flow installation and management algorithm (OFPE) using the SDN protocol OpenFlow, which preserves the controller to a non-overloaded CPU state and allow it to dynamically add and adjust flow table rules to reduce packet delay and out-of-order packets. In addition, we propose OFPEX, an extension to OFPE algorithm that includes techniques for managing multi-switch environments as well as methods that make use of the packets interarrival time in categorising and serving packet flows. Such techniques allow topology awareness, helping the controller to install flow table rules in such a way to form optimal routes for high priority flows thus increasing network performance. For the performance evaluation of the proposed algorithms, both hardware testbed as well as emulation experiments have been conducted. The performance results indicate that OFPE algorithm achieves a significant enhancement in performance in the form of reduced delay by up to 92.56% (depending on the scenario), reduced packet loss by up to 55.32% and reduced out-of-order packets by up to 69.44%. Furthermore, we propose a novel placement algorithm for distributed Mininet implementations which uses weights in order to distribute the experiment components to the appropriately distributed machines. The proposed algorithm uses static code analysis in order to examine the experimental code as well as it measures the capabilities of physical components in order to create a weights table which is then used to distribute the experiment components properly. The performance results of the proposed algorithm evaluation indicated reductions in delay and packet loss of up to 65.51% and 86.35% respectively, as well as a decrease in the standard deviation of CPU usage by up to 88.63%. These results indicate that the proposed algorithm distributes the experiment components evenly across the available resources. Finally, we propose a series of Benchmarking tests that can be used to rate all the available SDN experimental platforms. These tests allow the selection of the appropriate experimental platform according to the scenario needs as well as they indicate the resources needed by each platform.
