Full textThis dissertation is a historical project that traces the development of notable strands of composition pedagogy first crafted by Gregory Ulmer in his 1984 Applied Grammatology that continue to the present day, and groups them together in how they are incorporating multimodal tools in writing instruction that demand innovation in composition instruction. This will demonstrate how the work of certain contemporary composition scholars can be seen as creatively re-working the invention model that was devised and promoted by Ulmer in 1984. Through this history of invention in composition, Ulmer's invention model of writing instruction is clearly seen as both situated within a contemporary American Romanticism, and influenced heavily by Derridean deconstruction, and I will show that today's scholars who are students of Ulmer's invention model are creating pedagogy that effectively bring together elements of both Romanticism and Deconstruction.

This thesis explores the intersection of craft and electronics by way of paper and conductive ink, a domain that I'm terming papercraft electronics-a synthesis of electronics, drawing, and painting. I investigate the nature of making a physical electronic artifact, and the ways in which that making informs our relationship with both the artifact, specifically, as well as technology writ large. I examine craft-the manual process-as a means for embedding new kinds of personally-significant meaning in electronics, re-positioning electronics fabrication as the creation of personal, unique, hand-crafted artifacts. I do so through a series of case studies oriented around the papercraft electronics domain. Through a sequence of projects, workshops, and evaluations, I examine the personal connection and pride that comes with making, as well as the handmade artifact's place in technology. In particular, I initiate projects around the making of paper sensors, speakers, synthesizers, and audio-augmented artworks.

The physical user interface is an increasingly significant factor limiting the effectiveness of our interactions with and through technology. This thesis introduces Electric Field Imaging, a new physical channel and inference framework for machine perception of human action. Though electric field sensing is an important sensory modality for several species of fish, it has not been seriously explored as a channel for machine perception. Technological applications of field sensing, from the Theremin to the capacitive elevator button, have been limited to simple proximity detection tasks. This thesis presents a solution to the inverse problem of inferring geometrical information about the configuration and motion of the human body from electric field measurements. It also presents simple, inexpensive hardware and signal processing techniques for making the field measurements, and several new applications of electric field sensing. The signal processing contribution includes synchronous undersampling, a narrowband, phase sensitive detection technique that is well matched to the capabilities of contemporary microcontrollers. In hardware, the primary contributions are the School of Fish, a scalable network of microcontroller-based transceive electrodes, and the LazyFish, a small footprint integrated sensing board. Connecting n School of Fish electrodes results in an array capable of making heterodyne measurements of any or all n(n - 1) off-diagonal entries in the capacitance matrix. The LazyFish uses synchronous undersampling to provide up to 8 high signal-to-noise homodyne measurements in a very small package. The inverse electrostatics portion of the thesis presents a fast, general method for extracting geometrical information about the configuration and motion of the human body from field measurements. The method is based on the Sphere Expansion, a novel fast method for generating approximate solutions to the Laplace equation. Finally, the thesis describes a variety of applications of electric field sensing, many enabled by the small footprint of the LazyFish. To demonstrate the School of Fish hardware and the Sphere Expansion inversion method, the thesis presents 3 dimensional position and orientation tracking of two hands.

Full textA mobilidade elétrica pode ser um fator importante na promoção de um crescimento económico mais sustentável, mais inteligente e mais inclusivo. O objetivo deste estudo é analisar a viabilidade económica e ambiental dos Veículos Elétricos e Híbridos, em Portugal. Para isso, são estimados os custos totais suportados durante a vida útil do veículo em três perspetivas: consumidor, sociedade e emissão de Dióxido de Carbono; para três tecnologias distintas: elétrica, híbrida e convencional. É também realizada uma análise de sensibilidade. Os resultados obtidos indicam que nem o veículo elétrico nem o veículo híbrido são competitivos no mercado automóvel português, por enquanto.
This paper aims to estimate the costs and the performance of an electrically powered and a hybrid electric vehicle (HEV) in relation to a conventional internal combustion engine car in the consumer, society and the exhaust Well-to-Wheel (WtW) carbon dioxide (CO2) emissions, using portuguese data. This goal will be achieved by building a total ownership cost model. A sensibility analysis is also conducted to assess the impact of alterations on the values of the key parameters. The results of this study suggest that neither the hybrid electric vehicle neither the battery electric vehicle (BEV) are yet competitive with the internal combustion engine vehicle (ICEV) in the Portuguese market.

Full textIn recent years, electric vehicles have come to the forefront of public transport policies. They are seen as remedy for various pressing public concerns and are thus increasingly benefiting from supportive policy measures. Such measures remain contested: their impact on actual vehicle uptake rates, their sustainability, usefulness and justification are far from being self-evident. This study aims at uncovering the effect of financial demand-side public policy measures on i) the uptake rate of electric vehicles among private households in France, and ii) the public budget. First, the context within which electric vehicles are to evolve is sketched. A comprehensive overview of the potential opportunities that come with the introduction of electric vehicles is given. An international policy review depicts public policy levers that are currently deployed in order to support the uptake of electric vehicles. A focus is put on financial demand-side measures. Preliminary conclusions on their effectiveness with regards to observed electric vehicle uptake rates in the various countries reviewed are drawn. Next, the potential market for electric vehicles among French households is explored. Besides financial aspects, socio-economic obstacles to electric vehicle uptake among private households are analysed. With the aid of scenario analysis that accounts for the many uncertainties with regards to future vehicle developments, costs and market trends, a forecast of the electric vehicles' potential up until 2023 is given. The applied disaggregate approach based on the database of the French National Transport Survey 2007/2008 allows identifying the most promising sets of financial public policy measures that are likely to guarantee certain electric vehicle uptake rates over the next decade. Lastly, the effect of replacing one conventional vehicle by one electric vehicle on the public budget is investigated. Both, vehicle manufacture and use aspects are considered. The set up valuation model hereby accounts for direct and indirect financial impacts on the public budget. These comprise direct purchase subsidies, tax breaks, and tax income, as well as effects of changing employment situations that alter the amount of social contributions and unemployment benefits .The study's findings and considerations allow for various suggestions for vehicle manufacturers and policy makers willing to support the uptake of electric vehicles. These are listed in the conclusions section which also sketches directions for further research

Full textUno de los principales desafíos en el desarrollo futuro de los sistemas eléctricos es la incorporación costo efectiva de recursos renovables. En ese sentido, Latinoamérica cuenta con un alto potencial renovable; sin embargo, las metas esperadas por cada uno de los países de la región son aún conservadoras. La hipótesis de este trabajo es que la integración eléctrica entre los países de la región Latinoamericana puede permitir una mayor participación de generación renovable sin incrementar los costos totales. Este estudio incluye una revisión de otros estudios enfocados en Latinoamérica en relación con la integración eléctrica, con el objetivo de incluir enfoques metodológicos o elementos utilizados. Estos trabajos han sido también considerados como referencias para definir candidatos de interconexión. Por otro lado, para tener una mejor comprensión de la realidad en Latinoamérica, se ha llevado a cabo una revisión de los sistemas eléctricos actuales y proyecciones para cada país de la región. Adicionalmente, esta revisión es utilizada para completar la base de datos de cada país. Para validar la hipótesis planteada, este trabajo propone una metodología de escenarios incrementales donde puede ser comparado el costo total de cada caso. En todos los casos, es aplicado un modelo que minimiza el costo de inversión en generación y transmisión y el costo de operación del sistema eléctrico en un horizonte de 15 años. Para este propósito, se llevó a cabo e procesamiento de parámetros de entrada, la confección de series sintéticas de caudales hidráulicas y definición de su topología hidrográfica, definiciones de nuevas restricciones, y un marco de validación para cada país; los que fueron integrados a la herramienta de planificación. El escenario de referencia considera una proyección bussiness as usual, sin un mayor desarrollo en energías renovables y considerando las interconexiones actuales y planificadas. El segundo escenario es intensivo en generación renovable. Se establece una meta de generación renovable a cumplir para el final del horizonte, pero sólo las interconexiones actuales y planificadas son consideradas. Finalmente, el tercer escenario es un caso renovable integrado, donde, además de la meta renovable, se permite el desarrollo de nuevos candidatos de interconexión en la región. Con estos escenarios, es posible comparar el costo total de inversión y operación para concluir si el escenario renovable integrado permite una mayor participación renovable con un menor costo total para la región. Este trabajo permite concluir, en primer lugar, que la metodología de escenarios incrementales es apropiada para cuantificar los beneficios de una red integrada para alcanzar una matriz eléctrica altamente renovable en Latinoamérica. De acuerdo con los resultados obtenidos, es posible afirmar que un escenario con alta integración puede alcanzar una alta participación renovable sin incrementar el costo total.

Full textElkvalite är ett samlingsnamn för störningsfri energileverans. I takt med att eknikutvecklingen producerar mer komplexa apparater anslutna till elnätet så ökar kraven på törningsfri elleverans. Syftet med rapporten var att sätta sig in i begreppet elkvalite för att edan undersöka elkvaliten på utvalda platser vid E.ONs kraftvärmeverk på Händelö. xamensarbetet är utfört hos företaget ES ElektroSandberg som har bemanning på Händelö. tifrån analysen var det meningen att resultat skulle redovisas samt att eventuella tgärdsförslag ges. De senaste 10-15 åren har det fokuserats mycket på övertoner och dess inverkan på elnätet när an talar om elkvalite. Det är då lätt att dra slutsatsen att övertoner skulle vara ett stort roblem i våra elnät men så är inte fallet. Visserligen kan ett nät som uppvisar större mängder ara ett problem men det största problemen i elnäten är de spänningsvariationer som erhålls. ärför har det i rapporten inte bara fokuserats på övertoner utan på fler störningsmoment som ehandlar elkvalite. Mätningar har utförts med en inlånad nätanalysator C.A 8334, från företaget CA Mätsystem B. Mätningarna har skett under ett dygn där data sedan överförts till en dator för att sedan unna analyseras. Rapporten inleder med övergripande teori för att ge en så bra plattform som möjligt för nalysen och slutsatsen. Efter teorin presenteras företagen. Detta följs av en redovisning av de resultat som nätanalysatorn erhöll. Slutligen avslutas rapporten med en slutsats och diskussion ring resultatet. Slutsatsen behandlar vissa problematiseringar där det är nödvändigt att granska mer rocessmässigt. Generellt är det inga större övertonsnivåer i de ställverk där mätningar har tförts. Övertonsnivån är störst vid frekvensomriktarna vilket inte var någon överraskning. I ransientanalysen påträffas flera stora transienter som kan medföra skador på utrustningar om e inte är dimensionerade för stora transienter. I diskussionen presenteras också förslag till framtidaarbeten inom anläggningen.

Full textPassagerarflygplans framdrivningssystem är idag dominerat av turbo-jetmotorer som använder sig av fossila bränslen. Denna icke hållbara lösning är ett bekymmer både ur en ekonomisk och en miljömässig synvinkel. Denna forskningsstudie identifiera de begränsande faktorerna för att uppnå tillverkning och användningen av elektriska passagerarflygplan med hjälp av batteri, och förutsäga omfånget som går att uppnås i dag och inom överskådlig framtid. En litteraturstudie genomfördes för att hitta nödvändiga prestanda-data för alla tekniska komponenter. För att analysera resultatet av ett elektriskt framdrivningssystem, var Boeing 787-8 valts som en referens och en jämförelse. Piano-X är ett program som används för att simulera prestanda hos olika flygplan under olika förhållanden. Detta program användes för att få uppgifter om bränsleförbrukning och för att få fram prestanda-data för flygplanet. Den gravimetriska energi-densiteten hos batterierna upptäcktes att vara den störst begränsande faktorn. Elektriska motorer och kraftelektronik befanns sig ha ungefär samma prestanda som en modern turbo-fläktmotor, i befattning av gravimetrisk effekttäthet. Resultaten visade att med dagens batterier, som har en energitäthet av 250 Wh/kg, är räckvidden begränsad till ca 600 km, med antagande av en 40 % cellmassfraktion och 25 % förminskning av total energiåtgång under flygning. Sammanfattningsvis är utmaningen i att skapa en övertygande hel-elektrisk passagerarflygplan stor, men inte omöjligt. Förutsatt att batteriteknologin fortsätter att förbättras i nuvarande takt, och designoptimeringar görs för flygplanen, är en räckvidd över 1400 km möjligt inom de närmaste tio åren.

Full textI dagens samhälle är det vanligt att elnätet får driva olinjära laster. Dessa laster bidrar till problem på elnätet. Examensarbetet beskriver olika typer av problem som kan uppstå, med specifik inriktning på ett problem hos Billerud AB i Skärblacka. Det handlar om att ta reda på vad som orsakar för hög uppvärmning hos en av deras transformatorer. Rapporten inleds med en teoridel som beskriver olika begrepp inom elkvalité samt nödvändig information, som har instuderats inför examensarbetet. Efter teoridelen beskrivs systemet upp och de övertons- och osymmetrimätningar som gjorts för att kunna analysera uppvärmningsproblemet. Mätningarna loggades under några dagar för att kunna få med olika driftfall och se ifall dessa inverkar på övertonsinnehållet. En simulering av den aktuella systemdelen har utförts och den indikerar att problemet inte uppkommer på grund av onormal inverkan från frekvensomriktaren i systemet. Undersökningarna visar att det kan vara transformatorn som inte är tillräckligt dimensionerad för övertoner, vilket skulle leda till att den blir för varm. Undersökningarna visar också att frekvensomriktaren håller de prestandamått rörande övertoner, som har utfärdats från dess leverantör. En svårighet under examensarbetet var att kunna mäta på alla punkter som finns. Eftersom det handlar om höga spänningar och strömmar är det svårt att komma åt alla. Ytterligare mätningar skulle leda till en djupare analys. Rapporten avslutas med olika återgärds förslag samt förslag till fortsatt arbete.

Singing the Brain Electric Brain pacemakers, scientists have found, can treat depression by correcting neural circuitry gone haywire. This thesis examines how such technology - a technique known as deep-brain stimulation, in which electrodes are implanted within the brain - was developed and how it works. We are introduced to a patient who received deep-brain stimulation for her refractory depression, and consider the risks, ethical issues, and questions of humanity and identity the technology raises.

Because the country's financial system is not sound, the investment channel is limited, a large amount of capital is backlog into the stock market, and many stock prices deviate from the actual value, so the evaluation of enterprise value becomes more and more important. This project analyzes the financial condition and company value of GREE electric appliances, and puts forward constructive suggestions accordingly.
