The body exists in space and time. It moves through cultural spaces and temporal rhythms. In the combination of instantiated actions and environmental conditions a context is created, this through embodiment. In this thesis I will attempt to link definitions of embodiment with the process of creating and performing new sound theatre works that involve live interaction with media technology. I will also examine terms such as inscription or incorporation and their application to processes of learning and memory within a particular context of inter-disciplinary skills. Finally, in the light of this genre, I will approach the problematic of analytical procedures that change the very parameters of embodied knowledge. The term sound theatre could be defined as a shift of play between music, image and text, incorporating elements such as gesture, choreography, audio and visual technology into a compositional dialogue. However this approach demands a re-examination of the spatial and temporal aspects involved in such inter-activity and their consequent relation to the performer. Taking the starting-point of sound and movement within the body of the performer, my research involves investigations into medial extensions of embodiment that have developed through a discourse with machines. This project takes an essentially practical basis for its research in the form of collaborations with musicians and practitioners of media technology towards a creative product. The result is a series of written compositions, each of which examines a different aspect of sound theatre. The valuable exchange that takes place during such a situation of experimentation becomes equally as important as the final product, providing much of the material framework for issues such as terminology and analytical procedures that concern my investigation.

Os sensores com grade de Bragg são utilizados para quantificar e medir vários parâmetros como: temperatura, pressão, tensão, corrente elétrica e termodinâmica, com grande precisão e resolução. Neste contexto, foi desenvolvido um nova técnica de baixo custo para interrogar um sensor com grade de Bragg e medir temperatura. O sensor FBG é iluminado com um laser DFB, que contém um peltier (Thermo Electrical Cooler - TEC) e um termistor. Um circuito eletrônico analógico controlado por um microcontrolador de alto desempenho (100 MIPS) varia o TEC com correntes controladas, alterando a temperatura do laser DFB e, consequentemente, modifica o comprimento de onda em sua saída. Esta simples técnica de baixo custo e boa precisão é capaz de detectar a grade de Bragg no espectro da fibra e calcular de forma indireta a temperatura no ponto / Abstract: The recent advances in fiber optics and eletronic circuits has led to the development of many sensors based on fiber optics, with a great emphasis on Fiber Bragg Gratings (FGB) sensors. The FGBs sensors are used to quantify severeal measurands, as temperature, pressure, tension, thermodynamics and electrical current, with good accuracy and resolution. In this projec, a novel low cost technique for interrogating a temperature FBG sensor was developed. The FBG sensor is iluminated with a DFB laser which contains a Thermo Electrical Cooler (TEC) and a thermistor. An eletronic analog circuit controlled by a high-performance 100 MIPS 8051CF120 microcontroller drives the TEC with a controlled current, changing the temperature of the DFB laser and, consequently, changing the wavelength in its output. The FBG temperature measurement is implemented with an algorithm stored in the microcontroller flash memory. When the temperature changes in the FBG, the system has to con-tinuosly track the FBG as it moves around the spectrum due to the temperature variations. This novel simple low-cost and good precision technique for making an all eletronic interrogator for measuring temperature with FBGs sensors was develeped. The unique charecteristic of associating the Bragg shifts with thermistor measured values is the main feature of the proposed interrogation scheme / Mestrado / Eletrônica, Microeletrônica e Optoeletrônica / Mestre em Engenharia Elétrica

Algumas das principais características dos sensores a FBG são: imunidade à interferência eletromagnética (EMI), isolamento elétrico, baixo peso, flexibilidade, e transmissão de informações a longa distância. Eles estão sendo empregados na medida de temperatura, deformação, carga, tensão mecânica e vibração. Estão presentes também em estruturas inteligentes, onde sensores a FBG distribuídos são incorporados à estrutura, permitindo a monitoração em tempo real das condições estruturais de pontes, trilhos ferroviários e aviões. Este trabalho apresenta uma nova técnica de caracterização de FBGs utilizando deconvolução. Nesta técnica, utiliza-se uma FBG sintonizável, cujo perfil de reflexão é bem conhecido, para caracterização de outra FBG, cujo perfil é inicialmente desconhecido. Utilizando placas eletrônicas com componentes de baixo custo, e um software desenvolvido em LabVIEW®, no qual implementamos a deconvolução dos perfis das FBGs, essa técnica permite o levantamento do perfil de reflexão e outros parâmetros, como a largura espectral FWHM (do inglês Full Width at Half Maximum) e o comprimento de onda de Bragg 'lâmbda'B, de uma FBG. Os resultados obtidos tornaram possível a validação da técnica proposta e permitem concluir que ela é robusta e, com refinamentos matemáticos que podem ser implementados no processo de deconvolução, permite a construção de um caracterizador de FBGs preciso e de custo bem inferior a equipamentos disponíveis comercialmente / Abstract: Optical fiber sensors using fiber Bragg gratings (FBG) are becoming increasingly important, given the amount of applications in which they are being used. Some of the most important characteristics of FBGs are: electromagnetic interference (EMI) immunity, light weight, flexibility, and long range information transmission. FBG sensors are being used in the measurement of temperature, deformation, load, strain and vibration. They are also being used in smart structures, where several distributed sensing FBGs are embedded in materials to allow for the real-time monitoring of the structural conditions of bridges, railroad tracks and airplanes. A new technique for the FBGs characterization using deconvolution is presented. In this technique, a tunable FBG, whose reflection spectrum is known, is used to discover another FBGs profile, which is previously unknown. Using low-cost electronic parts and software developed in LabVIEW, which performs the deconvolution of both FBGs spectra, this technique allows the measurement of the FBG reflection spectrum, its FWHM (Full Width at Half Maximum), and the Bragg center wavelength 'lambda'B. The obtained results enables to validate the proposed technique, allowing concluding that it is robust and, if numerical refinement is implemented, it will be possible to build a low-cost FBG characterization device, in comparison with other commercial devices used for this purpose / Mestrado / Eletrônica, Microeletrônica e Optoeletrônica / Mestre em Engenharia Elétrica

Assim, este trabalho foi realizado com o objetivo de desenvolver um instrumento virtual para uso em experimentos com preparações biológicas, capaz de gerar estímulos, adquirir e processar os sinais biológicos decorrentes dos estímulos, a fim de propiciar um único ambiente que atenda ao máximo os requisitos de qualquer protocolo experimental que possa envolver estimulação, aquisição e análise de sinais. Foi então desenvolvida uma plataforma virtual para experimentos em preparações biológicas de modo a automatizar o protocolo experimental de um setup. Todo o desenvolvimento dos sistemas de controle, estimulação, aquisição e processa-mento do sinal do instrumento virtual foi concebido de modo a maximizar a flexibilidade no manuseio e a generalidade nas aplicações. O sistema desenvolvido foi capaz de controlar a geração e a aplicação de estímulos (pulsos de ultras-som de potência) em preparações in vitro de corações de ratos, tornando possível automatizar todo o protocolo experimental de estimulação, adquirir os sinais de temperatura e força de contração da preparação de forma síncrona ao estímulo e pós-processar os sinais adquiridos. O instrumento virtual pode ser aplicado em diferentes setups experimentais de preparações biológicas / Abstract: In experiments involving stimulation of biological preparations and their response expressed by a given acquired signal, control of the stimulation and monitoring of the signal are essential to better understand how the biological system reacts to the stimulation. This study was conducted with the aim of developing a virtual instrument for use in experiments with biological preparations, capable of generating stimuli, acquire and process the biological signals from stimulation, providing a unique environment that meets the maximum requirements from any experimental protocol that might involve stimulation, acquisition and signal analysis. A virtual platform was developed for controlling experiments with biological preparations, making possible to automate the setup. All the development of control, stimulation and acquisition systems, and signal processing of the virtual instrument was designed to maximize the flexibility in the use, and the generality of the applications.

The virtual instrument can be applied in different experimental setups with biological preparations / Mestrado / Engenharia Biomedica / Mestre em Engenharia Elétrica

Idag influeras samhället allt mer av digitaliseringens ständiga utveckling. Denna utveckling inkluderar nya digitala verktyg och processer vilka förändrar verksamheter och dess affärsmodeller. För revisionsbranschen tillkommer automatisering som ett komplement vilket ska effektivisera delarna i revisionsprocessen och möjliggöra att revisorer fokuserar mer på rådgivning. De digitala verktyg som digitaliseringen medför gör att de mindre revisionsbyråerna är utsatta för högre kostnader då implementeringen av verktygen är kostnadskrävande. Dessutom påverkas inte enbart kostnadssidan av digitaliseringen utan hela verksamhetens affärsmodell. Därav är studiens syfte att undersöka och analysera i vilken utsträckning revisionsprocessens delar har digitaliserats och digitaliseringens inverkan på affärsmodellen i små revisionsbyråer. Studiens vetenskapliga ansats är av deduktiv karaktär med semistrukturerade intervjuer. Delarna av revisionsprocessen är planering, granskning och rapportering. Vid undersökningen av affärsmodeller har delar ur business model canvas analyserats. De som undersökts är följande: kundsegment, kundrelationer, nyckelresurser samt intäkts- och kostnadsstrukturen. Resultatet påvisar att revisionsprocessens delar har digitaliserats olika mycket, planering- och granskningsfaserna har utvecklats mer av digitaliseringen än vad rapporteringen har gjort. Dock har samtliga delar effektiviserats mer på grund av de digitala verktygen som byråerna har implementerat. Under planeringsfasen har informationsinsamlingen underlättats då tillgången av information har ökat som ett resultat av internet. Vid granskningen har digitala verktyg, såsom analysverktyg underlättat och effektiviserat revisorernas arbete, detta eftersom redskapen medför att risker och avvikelser enklare framkommer. Avvikelser påträffas då revisorerna gör analyser genom stickprov ur SIE4-filer, vilka är kundens bokföringsunderlag. För rapporteringen, konstateras det att den delen är mitt i övergången gällande digitaliseringen. Det skapas fler digitala rapporter som sedan signeras digitalt jämfört med tidigare då all rapportering var i pappersform. För affärsmodellen fastställs det att fyra av de fem utvalda blocken har påverkats av digitaliseringen. Digitaliseringen har medfört att byråerna nu kan utvidga sitt kundsegment mot övriga orter eftersom avstånden har minskat i form av att underlag skickas digitalt. Vidare har kundrelationerna stärkts eftersom revisorerna är mer lättillgängliga och kan svara på kundernas frågor snabbt. Implementeringen av digitala verktyg har medfört högre kostnader för byråerna, dock kompenseras detta genom att de tar in fler kunder. Det blocket som inte har påverkats av digitaliseringen är nyckelresurserna: de immateriella tillgångarna och humankapitalet. Endast de materiella tillgångar har påverkats då byråerna har behövt införskaffa mer inventarier. / Today, society is increasingly influenced by the constant development of digitalization. Thisdevelopment includes new digital instruments and processes that change businesses and theirbusiness models. For the auditing industry, automation is added as a complement, which willstreamline the parts of the auditing process and enable auditors to focus more on advice. Thedigital instruments that digitalization entails mean that the smaller auditing firms are exposedto higher costs as the implementation of the tools is costly. Furthermore, not only the cost sideof digitization is affected, but the entire business model of the business. Hence, the purpose ofthe study is to investigate and analyze the extent to which parts of the audit process have beendigitized and the impact of digitization on the business model in small auditing firms. Thestudy's scientific approach is of a deductive nature with semi-structured interviews. The partsof the audit process that were analyzed were planning, review and reporting. During theinvestigation of business models, parts of the business model canvas have been analyzed.These are the following areas that were examined: customer segments, customer relationships,key resources and the revenue and cost structure. The results show that parts of the audit process have been digitized to varying degrees, the planning and review phases have been developed more by the digitization than the reporting has done. However, all parts have been made more efficient due to the digital tools that the agencies have implemented. During the planning phase, information gathering has been facilitated as the availability of information has increased as a result of the internet. During the audit, digital tools, such as analysis tools have facilitated and streamlined the auditors' work, as the tools make it easier to identify risks and deviations. Deviations are found when the auditors perform analysis by sampling from SIE4-files, which are the customer's accounting basis. For the reporting, it is stated that the part is in the middle of the transition regarding digitization. More digital reports are created which are then signed digitally compared to before when all reporting was in paper form.  For the business model, it is established that four of the five selected blocks have been affected by digitization. Digitization has meant that the agencies can now expand their customer segment to other locations as the distances have decreased in the form of data being sent digitally. Furthermore, customer relationships have been strengthened because the auditors are more accessible and can answer customers' questions quickly. The implementation of digital tools has entailed higher costs for the agencies, however, this is compensated by the fact that they bring in more customers. The block that has not been affected by digitalization is the key resources: intangible assets and human capital. Only the tangible assets have been affected as the agencies needed to purchase more equipment.
