Orientador: João Antonio Pereira / Banca: Luiz de Paula do Nascimento / Banca: Roberto Gil Annes da Silva / Resumo: Esse trabalho discute o uso dos materiais piezelétricos, mais especificamente, o Polyvinylidene Fluoride (PVDF) e o Lead Zirconate Titatane (PZT) na análise modal experimental (AME) de estruturas mecânicas. Materiais piezelétricos, também chamados de materiais inteligentes, têm se consolidado como uma nova tecnologia que mostra um grande potencial de aplicação em diferentes áreas da engenharia. Esse tipo de material exibe um acoplamento entre multi-domínios físicos, como por exemplo o acoplamento eletro-mecânico, o térmo-magnético, etc. O acoplamento eletro-mecânico produz um deslocamento elétrico quando o material é sujeito a uma tensão mecânica (efeito direto) e um deformação mecânica quando esse material é submetido a um campo elétrico (efeito inverso). Assim, principalmente por conta desses efeitos, seu uso no campo da análise modal experimental torna-se uma interessante questão a ser investigada. A incorporação de novas tecnologias nos testes estruturais pode agregar novos conhecimentos e avanços tanto na análise modal baseada na relação entrada-saída da estrutura, quanto na mais recente técnica, a análise modal baseada apenas na resposta das mesmas. Os conceitos teóricos para o desenvolvimento são apresentados e discutidos neste trabalho, onde é mostrada a análise modal de uma viga utilizando tanto sensores e atuadores convencionais quanto os produzidos com materiais inteligentes. Os testes de análise modal da viga foram feitos utilizando diferentes combinações de sensores e atuadores e isso pode mostrar as diferenças da estimativa de modos utilizando materiais piezelétricos. Também é apresentada a formulação da relação entre os modos em deslocamento e os modos com diferença de inclinação obtidos com materiais piezelétricos e, finalmente, uma comparação dos resultados obtidos pelas diferentes técnicas. Os testes apresentados mostram...

Piezoelectric materials also called smart materials have becoming a consolidated new technology that shows a large potential of application for different engineering areas. These materials exhibit a multi physics domain field coupling like mechanical and electrical coupling domains, thermal and magnetic coupling and etc. The electro-mechanical coupling domains of the material produces an electric displacement when the material is subject to a mechanical stress (direct-effect) and a mechanical strain when the material is submitted to an electric field (inverse effect). So, mainly due to these effects, the use in the experimental modal analysis field appears to be an interesting issue to be investigated. The incorporation of this new technology in the structural tests might aggregate new acknowledgments and advances in the well consolidated input-output based modal analysis techniques as well as in the more recent output only-based modal analysis. This work aims to present some contribution in this area by using piezoelectric sensors, instead of the conventional ones like accelerometers for modal analysis of mechanical structures. The theoretical concepts and background for the developing of the work are presented and discussed, it is also presented the modal analysis of a beam like structure using conventional sensors/actuators and piezoelectric materials. The modal analysis tests of the beam are conducted using different kinds of sensors/actuator and they give some insight of the difference of the estimated modes shapes by using piezoelectric materials. It is also presented a formulation that shows the relation between... (Complete abstract click electronic access below) / Mestre

Master of Science / Department of Computer Science / Mitchell L. Neilsen / Smart glasses, like smart phones, have separate operating systems, and can execute many different kinds of software and games. Smart glasses can be used to add a schedule, map navigation, interact with friends, take photos and videos, and make video calls with friends through voice control. They can support wireless network access through a mobile communication network. Bluetooth is a radio technology that supports short-range communication between of the devices. It can exchange information between devices including mobile phones, wireless headsets, laptops, etc. Bluetooth technology can effectively simplify the communication between mobile devices. This thesis focuses on smart glasses applications for high-throughput phenotyping which requires a data monitor, data synchronization, Bluetooth service, and voice control between devices. On the Android side, the application, which is extended, is called Field Book. The new software called Field Book AR, includes a data monitor module and a Bluetooth server module to achieve data exchange with smart glasses. On the smart glasses side, the application is called DataReceiver. It receives voice commands from users and controls the actions of Field Book AR. Also, when Field Book detects data changing, it accepts new data and shows changes to the users.

The Internet is gradually expanding to many new devices, in addition to its original native environment that was the Personal Computer. This wave started with mobile devices and as we enter the Internet of Things era, connectivity is possible from cars to light switches. One of the first devices, to follow mobiles, is the Television. Connectivity and two-way interaction on the TV device has in fact started even in the first days of the medium, but had failed to make it widely available, due to technological limitations of the past. Now, this has changed, with the Smart TV devices that can utilize the fast internet connections that are available in most developed countries. However, even though the technology and devices are now widely available there are still challenges in order to make the vast Internet and web content available in the Smart TVs. These challenges, have a familiar resemblance to what happened a few years ago, when internet connectivity was introduced on the mobile phone. Although, it was "feasible" to access any webpage from your mobile device, the experience for the user was often very frustrating, due to many factors, that derived from the fact that the web was designed for large screens and mice of the desktop computers, not the small touch screens and limited hardware of the phone. Nonetheless, these obstacles were successfully overcome, by introducing techniques and methodologies (e.g. Responsive Web Design) to make the web more mobile-friendly and also work from the manufacturers to improve their devices to this direction as well. The success of these actions is now evident, since the access to the web from mobile devices has surpassed the PC, and it is now a standard practice for every new website to be mobile-friendly. In this research work, we will attempt to do one very significant step towards this direction for the Smart TV. In other words, to discover what has to be done to make the web more TV-friendly. To do this, we explore many different TV devices from several manufacturers and see their similarities and differences. We explore numerous user studies and surveys to discover what is the problem in the Web experience on the TV, so that we can propose solutions to make web content TV-friendly. Based on these findings, we design prototypes and put them to the test on different devices and userevaluation. Finally, we propose a set of guidelines, that web designers can apply on their websites to make them TV-friendly, in the hope to introduce the first step towards a friendlier internet era for the TV.

Les systèmes pair-à-pair (P2P) sont utilisés par des millions d'usagers tous les jours. Dans beaucoup de cas, un usager souhaite communiquer, échanger du contenu ou des services à travers différents systèmes P2P. Cela requiert de la coopération entre les différents systèmes P2P, ce qui est très souvent difficile ou même impossible à obtenir, à cause des raisons suivantes; in primis, l'absence d'une infrastructure de routage entre les réseaux, ce qui rend la communication étanche et, in secundis, l'incompatibilité des protocoles et des opérations des susdits systèmes. L'objectif principal de cette thèse est celui de permettre la coopération entre systèmes P2P. La thèse introduit un cadre de coopération rétro-compatible entre systèmes P2P hétérogènes constitué de deux parties. La première est un cadre de routage intra-réseaux permettant à des réseaux hétérogènes de communiquer. La deuxième est une application coopérative, conçue à l'aide et au travers du cadre de routage, dont l'objectif est celui de résoudre les incompatibilités protocolaires des systèmes P2P sous-jacents. Comme étude de cas de notre cadre de coopération, on présente une solution complète permettant une coopération entre des réseaux P2P spécialisés dans l'échange des fichiers pouvant s'appliquer aux réseaux P2P actuels. Dans la deuxième partie de la thèse, on présente une étude de cas d'usage de notre architecture d'interconnexion des réseaux P2P pour la collecte et la gestion des données dans réseaux d'électricité intelligents. / Peer-to-peer systems are used by millions of users every day. In many scenarios, it is desirable for the users from different P2P systems to communicate and exchange content or services with each other. This requires co-operation between the P2P systems, which is often difficult or impossible, due to the two following reasons. First is the lack of an inter-overlay routing infrastructure throughout these systems, caused by the incompatibilities in overlay networks on top of which they are built. Second, there are incompatibilities in the application protocols of these systems. The main topic of this thesis is enabling the cooperation between P2P systems. The thesis introduces a cooperation framework for backward-compatible cooperating heterogeneous P2P systems which constitutes two parts. The first one is an inter-overlay routing framework which allows to inter-routing between heterogeneous overlay networks. The second one is the cooperation application, built on the top of the inter-overlay routing framework, which aims at solving the incompatibilities in the application protocols of P2P systems. As a case study of the cooperation framework, we introduce a complete solution for cooperating P2P file-sharing networks which is applicable for all current P2P file-sharing networks. In the second topic of this thesis, we investigate a case study of using inter-connecting P2P overlays for collecting and managing data in smart grid, a typical example of cyber physical system.

Brinquedos infantis tornaram-se sofisticados ao longo dos anos, evoluindo de produtos físicos simples a brinquedos que acoplam o mundo digital por meio de software e hardware. Com essa sofisticação, veio à tona potenciais problemas de segurança e privacidade infantil em relação ao uso de brinquedos inteligentes. Um brinquedo inteligente consiste de um componente de brinquedo físico conectado a um sistema computacional com serviços on-line para melhorar a funcionalidade de um brinquedo tradicional. Esse tipo de brinquedo ainda não é amplamente conhecido em países com economia em desenvolvimento, como o Brasil. Dessa forma, não se sabe a opinião de consumidores desse tipo de país em relação à aceitação dessa tecnologia quando ela estiver disponível. Esta dissertação de mestrado realizou um estudo comparativo entre países de diferentes níveis de desenvolvimento, avaliando a percepção sobre segurança e privacidade infantil em relação a brinquedos inteligentes. Aspectos como intenção de compra e percepção de inovação foram levados em consideração, pois essas duas percepções podem influenciar a percepção sobre segurança e privacidade infantil. Essas comparações de percepções ainda foram consideradas para variações de gênero e níveis de escolaridade, considerando pessoas de diferentes países de desenvolvimento. Com uma revisão sistemática, constatou-se que não há trabalhos que abordem a percepção sobre segurança e privacidade infantil relacionada a brinquedos inteligentes, comparando países de economia avançada e em desenvolvimento. Para a realização desta dissertação de mestrado, um survey com a aplicação de um questionário foi considerado. Antecedendo a aplicação do questionário, uma entrevista com 14 participantes foi realizada para refinar o questionário que estava em construção. Para analisar os resultados, os testes de estatística não paramétrica Mann Whitney e teste de Independência de Qui-quadrado foram usados para três hipóteses, considerando percepção sobre segurança e privacidade infantil, intenção de compra e percepção de inovação referente a brinquedos inteligentes em relação ao nível de desenvolvimento do país, tratando também de gênero e nível de escolaridade dos participantes. O primeiro resultado obtido, é que há diferença significativa entre os países de diferentes níveis de desenvolvimento em relação a segurança e privacidade infantil no uso a brinquedos inteligentes, sendo que, os países com economia avançada mostram maior preocupação. Em relação à intenção de compra e percepção de inovação, não foi detectada diferença significativa entre os países de diferentes níveis de desenvolvimento. Para co-variáveis como gênero e nível de escolaridade, há diferenças significativas de percepção em relação às três hipóteses se tratando de grupos específicos em relação ao nível de desenvolvimento de países. Por exemplo, testes realizados apenas com o gênero feminino, retornaram diferença significativa. Com os resultados deste mestrado, pesquisas maiores relacionadas podem ser consideradas. Além de que, estratégias de marketing podem ser melhoradas de acordo com as diferenças de percepções encontradas de pessoas que vivem em países de diferentes níveis de desenvolvimento / Children\'s toys have become sophisticated over the years, evolving from simple physical products to toys that engage the digital world through software and hardware. With such sophistication, potential child safety and privacy issues have surfaced concerning the use of smart toys. A smart toy consists of a physical toy component connected to a computer system with online services to enhance the functionality of a traditional toy. This type of toy is not yet widely known in economically developing countries such as Brazil. In this way, the opinion of consumers of this type of country is not known with respect to the acceptance of this technology when it is available. This master\'s research carried out a comparative study among countries with different levels of development, assessing the perception of child safety and privacy about intelligent toys. Aspects such as purchase intent and perception of innovation were taken into account, since these two perceptions may influence perceptions about child safety and privacy. These comparisons of perceptions were still considered for variations in gender and educational levels, considering people from different developing countries. With a systematic review, it was found that there are no studies that address the perception of children\'s safety and privacy related to intelligent toys, comparing countries of advanced and developing economies. For the accomplishment of this masters dissertation, a survey with the application of a structured questionnaire was considered. Before the application of the questionnaire, a interview with 14 participants was performed to refine the questionnaire that was under construction. In order to analyze the results, the non-parametric Mann Whitney test and the Chi-square Independence test were used for three hypotheses considering perceptions about child safety and privacy, purchase intention and perception of innovation regarding smart toys in relation to the level of the country\'s development, also dealing with the gender and level of schooling of the participants. The first result obtained is that there is a significant difference between countries of different levels of development regarding children\'s safety and privacy in the use of smart toys, and countries with advanced economies show greater concern. In relation to the purchase intention and perception of innovation, no significant difference was detected between the countries with different levels of development. For covariables such as gender and educational level, there are significant perceptual differences about the three hypotheses when dealing with specific groups about the level of development of countries. For example, tests performed only with the female gender, returned significant difference. With the results of this masters degree, major related research can be considered. In addition to that, marketing strategies can be improved according to the differences of perceptions found in people living in countries with different levels of development

O presente trabalho visa propor metodologia inovadora e abrangente que permita a avaliação sistêmica das diversas funcionalidades envolvidas no conceito de Redes Elétricas Inteligentes Smart Grids - (REI). Tal metodologia possibilita a avaliação de políticas de implementação destas funcionalidades de acordo com as características atuais das empresas, tendo como balizador central o benefício social fundamentado na visão dicotômica entre Concessionária e Consumidor. A metodologia proposta parte de modelagem inovadora de representação da rede e das funcionalidades emergentes de REIs, culminando em modelo de otimização que visa propor roadmaps tecnológicos fundamentados em avaliações de custos e benefícios de implantação. A importância das contribuições contidas na presente tese reside no fato de que o conceito de REI vem ganhando destaque nos cenários nacional e internacional, sendo apontado por especialistas do mundo todo como uma possível quebra de paradigma no setor elétrico. O referido conceito traz consigo uma série de funcionalidades e novas formas de integração e relacionamento entre os diversos agentes do setor. Tais funcionalidades necessitam de conceituação clara e objetiva, assim como metodologias de análise dos benefícios e dos custos decorrentes de sua aplicação nos respectivos segmentos do sistema de distribuição. Funcionalidades de REIs impactam tanto os processos de gestão do sistema de distribuição como os procedimentos de planejamento, operação e engenharia, além de permitirem ao consumidor, com possível papel adicional de produtor, maior gerência sobre seu consumo de energia. Diante de um cenário com diversos agentes, com alternância de papéis e com intensa interação entre si, somado às funcionalidades sistêmicas e de rede propiciadas pelos avanços tecnológicos crescentes, é fundamental uma análise global que estabeleça políticas ótimas de implantação das funcionalidades de REI, buscando a maximização do benefício social associado. Destarte, o produto principal desta tese, qual seja o modelo de proposição de plano ótimo de implantação de funcionalidades de REI, considerando os custos de implantação e os benefícios associados, não só ao setor elétrico, mas à sociedade como um todo, consiste em ferramenta valiosa para o planejamento de empresas concessionárias de distribuição na definição de roadmaps tecnológicos. Além disso, tal ferramenta permitirá a realização de estudos nacionais que fundamentem o balizamento de políticas públicas para o tema. / This thesis proposes an innovative and comprehensive methodology that allows the systematic evaluation of various functionalities involved in the concept of Smart Grids. Such methodology enables the proposition and evaluation of different policies for the implementation of smart grid functionalities according to the current characteristics of the utilities. Furthermore, the methodology is basically centered on the social benefits that consider a dichotomy view regarding Utility and Customer. This methodology considers an innovative model for network representation and Smart Grid emerging functionalities. Based on that, it leads to an optimization model that produces technologic roadmaps that take into account the evaluation of costs and benefits for the policies implementation. The importance of the contributions in this thesis lay in the fact that the concept of smart grids has been gaining attention in the national and international scenes, being pointed out by experts around the world as a possible paradigm break for the electricity sector. This concept brings a number of functionalities and new forms of integration and relationships amongst the various agents. These functionalities require clear and objective concepts, as well as methods for cost-benefit analysis regarding their implementation on the various segments of the distribution system. Smart grid functionalities impact most of the management processes in a distribution company as well as planning, operation and engineering procedures. Besides that customers are enabled to better manage their energy consumption, especially when playing the role of producers as well. Facing a scenario with several agents playing different roles with intense interaction, as well as systemic functionalities propitiated by advances in technology, one should devise a global analysis in order to establish optimal policies to implement Smart Grid functionalities, pursuing maximization of associated social benefits. In such a context, the main product of this thesis is an innovative model that produces optimal cost effective plans regarding the deployment of Smart Grid functionalities. Such a product is to be applied not only in the electricity sector but in society as a whole, consisting in a valuable planning tool for distribution utilities to define technological roadmaps as well as countrywide studies for the proposition of new public policies for smart grid implementation.

Traditionally the focus of cybersecurity has always been in IT, in order to protect the information and unauthorized access to information systems, use, modification or some kind of action that would compromise the confidentiality, integrity or availability of information. Cybersecurity for smart grid requires a combined focus of information security for IT systems to the communications network and the physical equipment of the electric grid.Thus, the thesis aims to develop a ranking methodology level cybersecurity maturity in smart grids. The methodology is based on two pillars, the first in identifying assets, threats and impacts and the second in carrying out a assessment for the analysis and classification of the 126 requirements maturity level that are grouped into 16 groups of requirements, always applied in a specific use case.The methodology was applied in two use cases of operating systems in a smart grid of a major power distribution company. The results clearly identify the proprietary system has 51% of the requirements at the lowest level while the new system 47% of applications are at the highest level. / O setor el?trico mundial est? passando por um momento revolucion?rio com da internet das coisas no sistema el?trico de pot?ncia, ou seja, as redes el?tricas inteligentes, no Brasil este movimento ainda ? embrion?rio, mas est? ganhando for?a nos ?ltimos anos impulsionado pela necessidade de efici?ncia operacional e o novo padr?o de consumidor mais participativo.As redes el?tricas s?o essenciais para o bem-estar f?sico e econ?mico de uma na??o, desta forma, com a implanta??o das solu??es de redes el?tricas inteligentes ? imprescind?vel que a seguran?a da informa??o seja considerada para proteger os ativos cr?ticos.

No. of bitstreams: 1 107110006.pdf: 2090462 bytes, checksum: 5fecbc3cc993bd7ac1637e41b7b2be41 (MD5) Previous issue date: 2012-10-19 / Com a total dependência pela energia elétrica em todos os setores da sociedade e a consequente regulamentação, é necessário que as concessionárias se preocupem em manter a continuidade do seu fornecimento, além de atender aos padrões que remetem à qualidade. A continuidade do fornecimento de energia elétrica é algo fundamental tanto para os consumidores quanto para a concessionária, a qual deixa de vender energia elétrica e ainda pode ser penalizada por interrupções muito longas ou em áreas críticas (hospitais ou indústrias, por exemplo). Como nem sempre é possível manter a continuidade do fornecimento devido a diversos fatores, sendo os defeitos permanentes os mais críticos, as empresas concessionárias são levadas a procurar novas metodologias e tecnologias para diminuir o tempo que o fornecimento de energia elétrica é interrompido. Nesse trabalho é descrita uma metodologia para o restabelecimento da energia em redes de distribuição de maneira automática. Essa metodologia se baseia no uso de tecnologias de comunicação e na automação dos equipamentos de manobras das redes. Com isso é possível obter os dados do estado da rede em tempo real, e é possível enviar os comandos para tais equipamentos de forma direta, sem a necessidade de intervenção humana. A metodologia aqui apresentada tem como objetivo detectar a localização de um defeito na rede através de leituras dos estados dos equipamentos, e então procurar as melhores manobras que restabeleçam o fornecimento ao máximo de consumidores sem que isso coloque todo sistema de distribuição, ou mesmo parte dele, em sobrecarga. Também é considerado que a rede pode ter sofrido alterações em equipamentos não automatizados (chaves manuais), e que as características de carga mudam no decorrer do tempo. Assim, a topologia deve ser atualizada antes de executar simulações e que os dados para tais simulações devem prever o comportamento da carga para o tempo que a contingência possa durar. Como teste da metodologia, foram executadas simulações em dados de redes reais de distribuição com diferentes topologias e diferentes cenários de defeitos. Os resultados obtidos foram satisfatórios na medida que tais soluções de restabelecimento eram viáveis em termos de carregamento da rede e foram calculadas em um curto espaço de tempo (poucos segundos). Essa agilidade traz vantagens tanto para os clientes quanto para a própria concessionária. / With the total dependency for electric power in all society sectors and the following regumen-tation, is necessary that the utilities worry in maintaining the continuity of power supply, in addition to meeting the standards that refer to quality. The continuity of power supply is fun- damental both for consumers and for the utility, which stops selling electricity and can still be penalized for too long interruptions or in critical areas (hospitals or industries, for example). As it is not allways possible to maintain the continuity of power supply due several factors, being the most critical the permanets defects, the utilities are driven to seek new methods and tecnologies to reduce the time that power supply is interrupted. In this work we describe a methodology for automatic restoration in power grids. This methodology is based on the use of communication technologies and automation equipment maneuvers networks. With this is possible to get the data status from the grid in real time, and also can send commands to these devices directly, without the need for human intervention. The methodology presented here tries to detect the location of a fault on the grid, through readings of the equipments status, and then search for the best maneuvers to restores supply to maximum consumers without putting the entire distribution system, or portion thereof, in overload . It is also considered that the grid may have changed in non-automated equipment (manual keys), and that the load characteristics change over time. Thus, the topology must be updated before running simulations and data for such simulations should predict the behavior of the load for time that can last contingency. As a test of the methodology, simulations were performed on real power grids data with different topologies and different scenarios defects. The results were satisfactory as such restoration solutions were viable in terms of network loading and were calculated in a short time (few seconds). This agility has benefits both for customers and for the own utility.
