Full textTo examine the conditions under which associations (nonprofit organizations) operate in the French prison system, and the ways in which they cooperate with the prison administration, this research focuses on the main leaders and coordinators of association networks in the “prison-justice” field (Secours catholique, Croix-Rouge, Genepi...). Most of these associations are active in prison or after release, carrying out social actions in the broadest sense of the term (material aid, training workshops, health prevention, etc.) for adults who are or have been in prison or on probation. They have the distinctive feature of being mainly made up of teams of volunteers potentially backed up by salaried staff, and of regularly interacting with the Direction de l'administration pénitentiaire (DAP), the French Prison Administration Department.On the one hand, the relevance of this approach is to question associative participation in public action in the penitentiary sector (which includes prison and probation): in its capacity to bring new services and public problems to the fore, to ensure actions throughout the country, and to influence the functioning of the system and politico-administrative decisions. On the other hand, it enables us to analyze how the State regulates these activities carried out by the private nonprofit sector. Associative interventions, particularly in prisons, are recognized by legislation but are scarcely regulated beyond simple access authorizations. Institutionalization has been carried out in a non-harmonized way, resulting in associations continuing to face disparate administrative treatments and discretionary decisions. Finally, the DAP has created a partnership arena at the central level, providing a forum for negotiation and confrontation, feedback, and leverage to support the development of associative networks.This thesis shows that, through the partnership framework of the associative sector, the central State is not so much disengaging as reconfiguring its actions from a distance. Over the twentieth century, the prison administration has seen many of its social, educational and health-related prerogatives withdrawn in favor of other public services. Nevertheless, it reaffirms its desire to develop a more comprehensive approach to caring for people, even though it leaves or delegates many aspects to associations. Based on its redefined objectives, the DAP formalizes its relationships through partnership agreements, and supports associations while evaluating them based on indicators. From this point on, the associative sector represents an interface between the repressive and social roles of the State. Thus, it faces tensions between participation and denunciation, civic engagement and free labor, all within the framework of asymmetrical and controlled cooperation

Este estudo investiga as práticas de gestão externa de custos mais utilizadas por empresas brasileiras. A motivação do estudo está no reconhecimento de que isoladamente a gestão interna de custos não é suficiente para o sucesso dos negócios. Para tanto, realizou-se um estudo descritivo, utilizando-se como procedimento técnico de coleta de dados uma survey, por meio de questionário, elaborado com base nas práticas de Gestão Externa de Custos - GEXC identificadas na literatura. Este questionário foi enviado pela internet para 250 das 500 maiores empresas constantes na Revista Exame Melhores & Maiores de 2008, das quais, 44 o responderam. Para analisar as informações obtidas por meio da aplicação desse questionário, realizou-se análise descritiva dos dados. Nesta análise foram utilizados gráficos com o objetivo de mostrar detalhadamente as respostas de cada afirmação. Utilizou-se também o ranking médio - RM para as afirmações que compõem o instrumento de coleta de dados utilizando-se a escala likert de 6 pontos. Na sequência, foi realizada a análise fatorial e análise de veriância, com a utilização do software statistical package for the social science (SPSS). Por meio dessas análises foi possível verificar que as empresas da amostra não adotam as práticas de GEXC com a mesma abrangência e profundidade que são tratadas na literatura, a qual descreve a sua relevância na gestão estratégica adotada pelas empresas. Além disso, verificou-se que poucos profissionais possuem experiência em GEXC. No caso da amostra pesquisada, apenas 25% deles afirmou ter experiência nessa área, ou seja, esses resultados sugerem que, no Brasil, a GEXC ainda está dando os primeiros passos. Foi possível ainda identificar, com relação à adoção de práticas de GEXC, que as ações mais amplamente utilizadas pelas empresas são: a) controle de estoque e entrega de determinados materiais diretamente nas linhas de produção do cliente; b) estabelecimento de metas de redução de custos para clientes; c) informações sobre o preço de venda do concorrente.
This study investigates the practices of external management costs most used by Brazilian Companies. The study is motivated by the recognition that, by itself, external management costs is not enough for business success. The technical procedure used for data collection was a survey through questionnaires based on the practices of external management costs, identified on the literature. This survey was send through the internet to 250 of the 500 biggest companies from Revista Exame Melhores & Maiores de 2008, in which, 44 answered it. To analyze the information from the questionnaires, a descriptive analysis of these data was made. In this analysis, graphics were used to demonstrate with details the answers of each assertion. Also the average ranking was used to the affirmations that compose the instrument to collect data using the Likert scale of 6 points. After, it was made a factorial analysis using the statistical software package for the social science (SPSS). Through these analyses it was possible to verify that Brazilian Companies do not adopt the practice of external management costs with the same rage and deepness as said on the literature which describes the relevance of these practices on the company´s strategic management. Besides that, it was verified that few professionals have experience with external management costs. Just 25% of the research sample confirmed to have experience in this field In other words, these results suggest that external management costs is giving the firsts steps in Brazil. It was also possible to identify that the practices most used by companies related to external management costs are: a) stock control and delivering of certain materials directly to client’s assembly line; b) setting cost reduction goals for clients; c) information about competitors’ sales prices.

The definition of the CubeSat standard boosted the research and development of the pico and nano satellites inside of the universities. Besides the standardization of the physical dimensions, the CubeSat specifies a communication protocol between the sub-systems of the satellite, what can make possible the shortening of the time and cost of the project using COTS (Comercial off-the-shelf) components. Although cost is an important requirement for the development of small satellites, the cost reduction must come from the correct architecture choice, not from the loss of system reliability. Focusing in a specific component, like the OBC (On Board Computer), becomes clear that the currents solutions meets the low cost requirements but fails in providing high failure tolerance. Some OBC models do not provide a mechanism of detection and correction of failures, while others cover only partially the failure points with a way to correct errors in external memories. At this job will be proposed an open source architecture with low cost and high reliability for an on board computer with compatibility with the CubeSat standard. The proposal architecture uses a TMS570LS0432 processor from Texas Instruments, which have dual ARM Cortex-R4 core, detection and failure correction in RAM and internal ROM, hardware BIST (built-in self test) at the CPU and RAM memory and others securities characters like clock monitoring and power supply voltage. An external flash memory was used for storage of code and data. Two I2C interfaces for communication between the sub systems, one had been used exclusively for transponder communication and the other one for the other systems. The architecture is complemented with an UART interface for diagnosis and debugging, PWM signals for activate the torque coils and ADC inputs for light measuring in the satellite. A MicroSD card reader has been planned for data storage and a CAN bus for data traffic in real time, ensuring a rigid control of failures and messages receiving. The OBC was electronically tested and is able to be embedded with the others sub systems.
A definição do padrão CubeSat impulsionou a pesquisa e o desenvolvimento de nano e pico satélites por parte das universidades. Além da padronização das dimensões físicas, o CubeSat também especifica um protocolo de comunicação entre os subsistemas do satélite, o que torna possível reduzir o tempo e o custo do projeto através do uso de componentes COTS (do inglês Comercial off-the-shelf ). Embora o custo seja um requisito importante para o desenvolvimento de pequenos satélites, a sua redução não deve decorrer da diminuição da confiabilidade do sistema e sim da escolha de arquiteturas adequadas. Focando em um componente específico, como o OBC (do inglês On Board Computer), fica claro que as soluções disponíveis atendem principalmente ao requisito de baixo custo, mas falham em oferecer alta tolerância à falhas. Alguns modelos de OBC não oferecem nenhum mecanismo de detecção ou correção de falhas, enquanto outros oferecem apenas uma cobertura parcial dos pontos de falha ao introduzirem lógica para correção de erros nas memórias externas. Neste trabalho, será proposto uma arquitetura open source de baixo custo e alta confiabilidade para um computador de bordo compatível com o padrão CubeSat. A arquitetura proposta utiliza o processador TMS570LS0432 do fabricante Texas Instruments, o qual possui: núcleoARM Cortex-R4 em duas CPUs; detecção e correção de falhas em suas memóriasRAM e ROM internas; hardware BIST (Auto-teste interno de fábrica) tanto na CPU quanto na memória RAM; e outras características de segurança como o monitoramento do clock e da tensão de alimentação. Uma memória Flash externa foi utilizada para armazenamento de código e dados. Foram disponibilizadas duas interfaces I2C para a comunicação com os subsistemas existentes em um CubeSat, sendo uma exclusiva para comunicação com o Transponder e outra comum para os demais. A arquitetura é complementada por uma interface UART para diagnóstico e depuração, sinais PWM para acionamento das bobinas de torque e entradas ADC para medição da intensidade da luz solar nas faces do satélite. Estão previstos ainda um cartão MicroSD para armazenamentos de dados e uma interface CAN para tráfego de informações transmitidas em tempo real, garantindo assim um controle rígido de erros e a recepção de mensagens. O computador de bordo foi eletronicamente testado e está apto à integração com os demais subsistemas.

Embora existam investigações teóricas e empíricas sobre consórcio modular, estudos sobre as relações entre os modulistas, o fluxo de informações e a Gestão Interorganizacional de Custos (GIC) em arranjos de consórcio modular são embrionários. O consórcio modular e a GIC induzem as empresas a ultrapassar as fronteiras organizacionais, no intuito de permitir que toda a cadeia de valor se torne mais eficiente. A presente tese, configurada com um Estudo de Caso com Objetos Incorporados, defende a possibilidade de aceitação que a associação entre consórcio modular e GIC promove mútuo aprendizado e maior redução dos custos globais de operações na cadeia de valor automobilística, do que adotadas isoladamente. Entende-se que as abordagens adotadas pelo consórcio modular de Resende (modularização e GIC) são complementares e incluem diversos fatores comuns, tal como a partilha de projetos de P&D, entrosamento de seus funcionários em outras empresas, sistemas integrados de informações, transferência de conhecimento, bem como a necessidade de desenvolvimento de uma gestão interorganizacional mais eficiente. Neste contexto, o consórcio modular constitui-se em um elemento facilitador do processo de GIC, pois o custo admissível dos componentes é definido por equipes interorganizacionais de trabalho, que incluem design de produto, engenharia, compras e engenharia de produção. Assim, as empresas demonstram possuir uma relação de alta interdependência. Porém resta evidente que, nem sempre, os benefícios são compartilhados entre todos os atores envolvidos, em função da assimetria de poder entre a MAN e os modulistas. No que tange à troca de informações de custos os achados indicam forte ocorrência desta iniciativa, porém somente dos modulistas para a MAN. As evidências empíricas obtidas no presente estudo denotam o uso de poder pela MAN aos seus modulistas. O uso do poder pode favorecer a divulgação de dados de custos pelos modulistas, mas isso não garante o êxito da GIC em toda sua plenitude. Essa é uma limitação para a aplicabilidade da GIC através do open book accounting.
Although there are theoretical and empirical research on modular consortium, studies on the relationship between modulists, the flow of information and the Interorganizational Cost Management (IOCM) in modular consortium arrangements are embryonic. The modular consortium and IOCM induce companies to overcome organizational boundaries in order to allow the entire value chain becomes more efficient. This thesis, configured how a Case Study with Embedded Objects, defends the possibility of accepting that the association between modular consortium and IOCM promotes mutual learning and further reducing overall operating costs in the automotive value chain, rather than taken alone. It is understood that the approaches adopted by the modular consortium in Resende (modularization and IOCM) are complementary and include several common factors, such as the sharing of R&D projects, meshing of its employees in other companies, integrated information systems, knowledge transfer as well as the need to develop a more efficient inter management. In this context, modular consortium is on a facilitator of the IOCM process because the allowable cost of the components is defined by inter-working teams, which include product design, engineering, procurement and production engineering. Thus, companies have shown a high interdependent relationship. But it is evident that not always, the benefits are shared between all the actors involved, due to the asymmetry of power between MAN and modulists. Regarding the exchange of the findings indicate a strong occurrence cost information of this initiative, but only the modulists for MAN. The empirical evidence obtained in this study denote the use of power by MAN to its modulists. The use of power may favor disclosure by modulists cost data, but this does not guarantee the success of IOCM in all its fullness. This is a limitation to the applicability of IOCM through open book accounting.

Full textIn the actual world with the importance of the Information Systems in the socio¬economic infrastructure, becomes relevant the study of this market. This thesis tried it, on the supply side through the feedback of some of the main software suppliers and on the demand side through the study of a sample of companies. The subject of study was the Operating Systems and Office Suites for personal computers and the analysis of competition between Open Source Software and Proprietary Software, although the thesis hypotheses and conclusions may extend to other software categories. On the market supply side we concluded that in the competition between two business models, Open Source Software and Proprietary Software, both can create innovation and ensure the survival in the market of the companies that use these business models. On the demand side, we concluded that in this market factors other than brand image, product features or price have influence in the purchasing decision. Factors like network effects, switching costs or lock-in have influence in the buying decision protecting the incumbent and decreasing the market competition level, making it difficult for the competitive alternatives based only on offer and price to gain market share to the incumbent.
No mundo actual a importância dos Sistemas de Informação na infra-estrutura sócio-económica torna relevante o estudo deste mercado. Esta tese procurou fazê-lo tanto do lado da oferta, através do feedback de alguns dos principais fornecedores de software, como da procura, através do estudo de uma amostra de empresas. Foram objecto de estudo os Sistemas Operativos e Office Suites para computadores pessoais e a análise da concorrência entre o Software Open Source e o Software Proprietário, embora as hipóteses e conclusões da tese possam estender-se a outras categorias de software. Do lado da oferta concluiu-se que na competição entre dois modelos de negócio, Software Open Source e o Software Proprietário, ambos podem criar inovação e garantir a sobrevivência no mercado das empresas que se baseiam nos mesmos. Do lado da procura concluiu-se que neste mercado outros factores para além da imagem de marca, características do produto ou preço têm influência nas decisões de compra. Factores como o efeito de rede, custos de mudança ou lock-in influenciam a decisão de compra protegendo o incumbente e diminuindo o nível concorrencial do mercado, tornando mais difícil às alternativas concorrenciais conquistarem mercado ao incumbente apenas com base na oferta e preço.

Full textThis research aimed to identify, by the perspective of the Transaction Cost Economics, how the Open-Book Accounting and the trust influence the satisfaction in the relationship between suppliers and buyer on the automotive sector supply chain. The research was developed through multiple cases study, characterized as explanatory, consisting in a automaker and three of its direct suppliers (first tier). For data collection were used, in addition to documental analysis, semi-structured interviews, in which the speech was analyzed using content analysis. The results show that the OBA is unilateral, forced by the automaker, thus becoming a selective information process, once the vendors try to, as far as possible, protect the value of their information. It was found also that the OBA is used mainly to price adjustments and in conflicting conditions based more on pressure to reduce costs than on joint strategies. The detail level of the information shared presents positively correlation with the probability of price adjustment grant claimed by suppliers. The results shows that the trust is just partial (calculative trust) and the cooperation is not spontaneous, being motivated by the search of benefits. It was also verified that, depending on how the information is used by the automaker, the OBA can have a positive or negative effect on the economic and social satisfaction of the suppliers. For the same reason, the OBA can either generate as much as destroy trust in the relationship. Although suppliers have reported high satisfaction with OBA, paradoxically it was found that none of them share their information spontaneously, leading to the conclusion that they perceive little advantage in the application of OBA. The results indicate that satisfaction of the automaker with the OBA is related to the level of information detail: the more detailed, the greater satisfaction of the automaker with the OBA and the economic-financial results arising from relationships (economic satisfaction). Finally, it was found that the trust has a positive influence on the economic and social satisfaction of both the automaker as suppliers. Generally, considering the analyzed cases, some conclusions could be drawn relative to the OBA in practice: (i) this tool have little utility; (ii) is distorted on its primary purpose - cost management in the supply chain -; (iii) does not necessarily generate benefits for all companies involved in the process; and (iv) it is not necessarily an IOCM tool. It was also possible to conclude that there is a detachment between literature and reality on the companies surveyed in relation to the matters dealt with in this thesis

Full textThe work developed at this thesis has been based on two main objectives. First, it was focused on the optimization of the steps and processes for the fabrication of high efficiency solar cells, reducing production costs. The latter objective was directed to develop solar cells that were efficient and non-dependent on impurities gettering performed through the aluminum diffusion. In order to attend the planned objectives the work was divided into the theoretical objectives and experimental developments. The theoretical optimizations were performed using two different program codes: one was developed at LME (simulacell.pas), being upgraded afterwards (version 2); and the other was acquired commercially, the PC1D. According to the obtained results in complete structures n+p and n++n+p, it was possible to conclude that the homogeneous and double diffused emitter structures can provide high efficiencies, from 25,5% to 26,0%, respectively, for a wide range of thicknesses and surface doping levels. Concerning the experimental developments, this work starts with a low cost simplified process, using Cz silicon solar cells with low base resistivity and the structure n+pp+, \"mesa\" type. This simplified process was also based on the phosphorus/ aluminum diffusion (P/Al), using industrial gases and for analysis grade chemical reagents, as a fabrication process transposition of the process previously developed at LME-EPUSP using silicon substrates with planar technology. The most representative solar cells of the implemented process, A-16-1, provided about a 17% efficiency. The experimental implementations aimed the development of procedure for starting material (silicon) qualification, by using the photoconductive decay technique (PCD) with two surface passivation procedures: thermal oxidation and light phosphorus diffusion. Later, using PCD system, new optimizations of n+ homogeneous emitters and p-type region were performed, followed by passivating thermal oxidations with hydrogenation, maintaining the volume lifetime at high values (approximately 1ms, after each thermal step). These results qualified the used silicon and the consumer materials, as well the new fabrication process developed. This technique has also allowed qualifying the processed Gaussian profile emitters, providing values about 45fA/cm2 for the recombination current density in n+pp+ structures. N+p structures were also developed using Cz silicon with low resistivity 2- 3W.cm of two different manufacturers and FZ with 0.5W.cm. It could be proved the quality of the steps of a complete optimized process resulting implicit open circuit voltages of 652.4mV (Cz silicon - manufacturer type 1), 662.6mV (Cz silicon - manufacturer type 2), and 670.8mV (FZ silicon). According to the theoretical simulations performed using the usual parameters of devices processed at LME (random chemical texturization and SiO2 film), efficiencies between 19%-20% can be reached. However, using a random texturization and a double layer anti-reflection system, a 21% efficiency becomes possible, surpassing the 17% barrier (national record), and proving the potentiality of this laboratory facility for the development of solar cells non-dependent on impurity gettering through the aluminum diffusion.

Full textO Software Livre e Aberto teve na última década um crescimento deveras interessante na forma como é desenvolvido, isto é, por comunidades de programadores e não por empresas tradicionais de software. A Administração Pública, por seu lado, usufruiu de fortes investimentos nas áreas de Tecnologias de Informação e Comunicação. Em função das duas realidades atrás expressas é natural que o Software Livre e Aberto tenha adquirido uma quota, não mensurável, de utilização na Administração Pública que até então era maioritariamente utilizadora de software proprietário. Não se conhecendo factos e números concretos quanto a essa utilização, apenas se consegue constatar que existem instituições a aderir e a implementar esse tipo de soluções. No âmbito deste trabalho contactaram-se os responsáveis técnicos ou gestores de algumas das instituições que estão a implementar soluções de Software Livre e Aberto. Através da realização de entrevistas, procurou-se compreender as principais motivações que impulsionaram essas instituições na mudança do tipo de software que utilizavam. A principal finalidade deste trabalho foi procurar identificar o "porquê" da mudança através do estudo de alguns casos. Constatou-se que algumas das alterações podem ter origem em razões de natureza política ou filosóficas, de cunho técnico, ou de cariz organizacional. Concluiu-se que os principais motivos apontados foram: o custo do licenciamento, a segurança da solução e a disponibilidade do código fonte.
In the last decade the Free/Libre Open Source Software (FLOSS) had a really interesting growth bearing in mind the way it is developed, that is, by developer's communities and not by traditional software companies. The Public Administration, in its turn, benefited of strong investment in the area of Information and Communication Technologies. Considering the two mentioned realities, it is natural that the FLOSS has obtained a non-measurable share of use in the Public Administration, until then, it was predominantly proprietary software. There are no absolute facts and figures about such use, but evidence points to a considerable rise on the number of institutions that are currently joining in the implementation of this type of solutions. The aim of this paper was to inquire managers or administrators of various institutions which already have implemented FLOSS solutions. The purpose was to conduct interviews, in order to understand the fundamental reasons these institutions decided to opt for this type of software. The main goal of this study was to identify the "why" of change through the study of some cases. We have established that change was originated by political-philosophical, technical or organizational reasons. The major justifications mentioned were: license costs, security and source code availability.

Full textIn the light of globalization, the enterprise environments are becoming more competitive; thus, increases the concern and the need to provide a management information system that is effective, reliable and relevant to assist managers to make intelligent decisions. With the use of principles and costing methods linked to services inherent in mining operations and methods, this work is intended mainly identify and understand the weaknesses of the current costing and production system and structure a systematic that supports performance evaluation productive-economic-financial in surface mining. The second objective of this work is to use standard cost method linked to production and business rules and validate it by comparing the accomplished against foreseen in surface mining, through the use of concepts of wastes, the principle costing of partial absorption, cost control and management for production to evaluation of results. The mineral extraction unit studied uses the open pit mining method and outsources the mining operations of pre stripping, drilling, blasting, rock excavation, loading and transportation. The outsourced company uses the costing principle of total absorption and the costing method is the cost centers. Thus, the systematic that support the evaluation of productive-economic-financial performance and the standard cost method were developed and validated in three outsourced services with the goal of verifying its functionality and practicality.

Full textIn their heyday, the World’s fairs, landmarks of the processes of globalization and modernization, did not lack a Chinese participation of multiform and multi-level in the main organizing country, France. The study of the Chinese presence follows chronologically these great events held in Paris, case by case, for nearly a century. The representations treated evolved with time, according to the international context, the Franco-Chinese relationship and the political regime. The question of clarifying the facts and specifying the limits of the place of this country in the French World’s fairs is the origin of the present study. At the end of the dynasty, imperial maritime customs under the direction of foreigners strongly influenced the organizational procedures. Witnessing the mutation of economic life, national pavilions in Paris revealed both the imbalance of the geographical distribution of trade and the disparity of the industrial structure in this country. At the same time, cultural and artistic events presented a continuity that survived the changes. Moreover, the analysis of these participations allows us to examine the possible capacity to present itself on the international scene, as well as to evaluate the first efforts of Chinese industrialization. This thesis aims to draw up an assessment of Chinese participations in France, in order to contribute to one aspect of the history of exhibitions in modern China

The purpose of the research was to investigate the difference between Custom tip and Dome on occlusion, gain, the function of signal processing, and satisfaction when fitting open-fit hearing aids. The experiment research method was adopted. According to different research goals, there were four experiments. The samples and results were described as follows: 1、 The occlusion and occlusion effect was evaluated via objective and subjective methods. On the part of objective method was Real Ear Measurement(REM). The results included:(1) Dome was significantly smaller than Custom tip on REOR-REUR(OU) and REAR-REUR(AU) when the input sound level was 50 dB SPL,(2) When the input sound level was 65 dB SPL, Dome’s OU was significantly smaller than Custom tip’s at 750Hz and 1000Hz. There was no significantly difference between Custom tip and Dome on AU. On the part of subjective method was Q8 and Q9 of the open fitting hearing aids’ satisfaction inventory. The result shows there were no significantly difference between Custom tip and Dome on these two questions. But the Custom tip was same as Dome(48%) on the occasion effect, even better(37%). 2、 The REIG and functional gain did not differ between Custom tip and Dome, regardless of whether 50 dB SPL or 65 dB SPL input sound level were used. Both REIG and functional gain were significantly different within different frequencies(p<.001). 3、 SRT on quiet condition(M=29.81) was significantly better than noise conditions(M=32.67)(p<.01). Using Custom tip(M=30.58) also could achieve better SRT than using Dome(M=31.89)(p<.001). There were no significantly differenct on microphone setting, noise reduction, and the interaction within variables 4、Two methods were used to compare the usage of Custom tip and Dome via the open fitting hearing aids’ satisfaction inventory. There was no significantly difference between Custom tip and Dome on overall subjective rating. However, choosing one of the following solutions set Dome, Custom tip or Same in each questions of the inventory, both the option of Same and Custom tip were significantly more than the option of Dome(p<.01). The recommend about research and clinical field also mentioned in the thesis.

Full textNesta tese, é apresentada uma plataforma IoT desenvolvida através da utilização de tecnologias open source, seguindo uma abordagem de componentes flexíveis. A arquitectura da plataforma está dividida em múltiplas camadas providenciando assim a flexibilidade necessária para permitir a integração de gateways e application servers personalizados. A plataforma IoT proposta suporta a integração de tecnologias Low Power Wide Area Network (LPWAN), tal como LoRa, recorrendo a uma implementação adaptada no network server. O network server suporta comunicações uplink/downlink com uma interface Message Queing Telemetry Transport (MQTT). Este trabalho pode ser aplicado em zonas remotas, como por exemplo, em áreas rurais com o objetivo de suportar o desenvolvimento de soluções IoT. Para que seja possível sustentar vários aparelhos IoT através de diferentes tipos de networks, é necessária uma abordagem multi-protocolar para a plataforma proposta. O principal objetivo desta pesquisa foi providenciar uma alternativa de baixo custo, multi-protocolar e leve, com a implementação de tecnologias longo alcance que sustente aplicações IoT, gateways, aparelhos e os seus respetivos sensores/atuadores.

Porém, a análise morfológica necessita de investigação mais aprofundada. crucial acerca dos fenómenos fisiológicos que ocorrem no sistema cardiovascular. Esta análise pode ser mais detalhada e alargada quando estes dados são transpostos para a análise da Variabilidade da Frequência Cardíaca (VFC). Desta forma, para além dos marcadores da VFC, que fornecem dados sobre funcionamento do coração, modulados pelo Sistema Nervoso Autónomo, é também possível obter informação acerca da condição física do indivíduo, ou, até mesmo, do seu estado mental e psicológico. Com a proliferação de ferramentas, quer de hardware, quer de software, de baixo custo, torna-se possível contornar algumas das limitações de acesso a equipamento médico e respetiva análise destes dados. Juntando ao baixo custo a liberdade do utilizador em configurar o sistema segundo as suas necessidades específicas, numa abordagem “faça você mesmo” (Do-it-Yourself ou DiY ), transcende-se o potencial relativo à eficiência nos processos de monitorização, aumentando exponencialmente a capacidade de recolher dados que, no limite, ajudarão a dar resposta a questões que surgem no meio clínico, científico e tecnológico. Abrem-se, assim, novas oportunidades de experimentação e desenvolvimento de metodologias ou prova de conceitos, para aplicações baseadas em biosinais. Com base em trabalhos anteriores encontrados na revisão da literatura, esta dissertação pretende analisar a fiabilidade de um dispositivo de baixo custo e DiY para análise rítmica do traçado de ECG. Para isso, foram realizadas monitorizações numa população de 21 indivíduos em condições de repouso e posterior corroboração empírica dos dados numéricos obtidos com os dados recolhidos, à priori, por um dispositivo médico. Como uma das bases de análise tomou-se o Intervalo QTc para a Frequência Cardíaca. Foram, ainda incluídos os resultados extraídos a partir de 2 casos de estudo, no âmbito de um estudo exploratório inicial: em um dos indivíduos foi detetada uma forma de onda anómala, posteriormente confirmada como sendo de origem cardiopática; no segundo indivíduo, foram feitas monitorizações em condição de repouso e dinâmica, para as quais foram realizadas as avaliações qualitativas dos segmentos de onda de ECG, para posterior análise rítmica, bem como a análise numérica dos dados da VFC. Os resultados demonstram que a qualidade do sinal adquirido é fiável para a aquisição de ECG com vista à posterior análise rítmica, tanto em condição de repouso, como dinâmica, através das derivações bipolares aplicadas. Foram também detetadas evidências promissoras para a monitorização e prevenção de patologias cardiovasculares, que sugerem o benefício da inclusão de análise morfológica da forma de onda de ECG com recurso às ferramentas utilizadas neste estudo. Porém, a análise morfológica necessita de investigação mais aprofundada.
Electrocardiographic (ECG) data analysis can reveal crucial information about the cardiovascular physiological phenomenon. This information can be further enhanced through Heart Rate Variability (HRV) analysis, that allow the comprehension of the landscape of the Autonomic Nervous System modulation. Hereupon, beyond cardiovascular diagnosis, ECG markers can also reflect workload levels, or even physical and mental performance, through this method. The proliferation of low-cost and Do-it-Yourself (DiY) tools, wether software or hardware tools, has allowed multiple enabling technologies, by allowing the access to devices that can have great potential for biosignals monitoring. For these reasons it has been achieved great advances in research and product development, due to the easy access to develop proof of concept methodologies and prototypes for biosignal applications. Beyond those reasons, the time and costs reduction when using such tools, when comparing with standard medical devices, also represents the main reasons for adopting these choices. Building upon previous work found within the state-of-the-art, this thesis explores the potential of using a low-cost device for ECG signal analysis. With the aim of performing the rhythmical analysis, empirical tests were performed in a population of 21 control subjects in a resting position, for further corroboration of this data with the numerical data, previously acquired, from a medical grade device. The QTc Interval for Heart Rate has been accomplished for both devices, and it was used for this comparison. Also, 2 subjects were additionally included in this research: in one of them it was detected a waveform abnormality, further confirmed as a cardiopathy; the second has performed the recordings in rest and dynamic condition, in the scope of the initial exploratory research, where ECG wave segments analysis and HRV features extraction for numerical analysis were accomplished. Results have demonstrated that the signal quality allows reliable ECG acquisition for further rhythmical and HRV analysis, in stationary and dynamic monitoring, for the bipolar leads applied. There was also evidence that suggest a benefit from including ECG morphological analysis with this hardware and software setup for prevention and diagnosis of cardiovascular disorders, although requiring further investigation.
