I investigated its insertion and participation in the groups of production, associations, as element of construction in new ways of organization, based in the collective work, cooperated and in the self management. I looked for to reveal not only the perspectives of work and meanings attributed to this work for the young, but by means of its form of organization and production, I searched to identify elements produced in these experiences that contributed for a bigger social production – the knowledge and significant learning’s in fight of the popular layers, in a perspective of opposed-culture, Popular Education. The way covered for elaboration of this study is placed in the unit between dialogue, reflection and theoretical deepening, in a methodological perspective of insertion in the groups, participant observation, application of questionnaires, interviews and discussion groups and, still, the use of the photograph, music and video as elements boosters of expression of the subjectivity. This research way it’s based in a perspective theoretician-methodological of ethnographic type, that emphasizes the attempt of comprehension of the elements that they form the cultural and conceptual universe of the participants. The findings reveal that these groups, producers of against-culture, are placed in a platform of exploration and capitalist reproduction for the interaction with the market organized for this system, but at the same time collaborates in the production to knowledge that, allies to an organization and technician-scientific systematization, for the interaction theoretician-practical it can contribute in the sphere of the against-hegemony. / Este estudo dá vida à juventude, entendendo esse segmento como atores sociais e, portanto, capazes de atuar em seu espaço para transformá-lo. Investiguei sua inserção e participação nos grupos de produção, associações, como elemento de construção de novos modos de organização, alicerçados no trabalho coletivo, cooperado e na autogestão. Procurei desvelar não apenas as perspectivas de trabalho e significados atribuídos a esse trabalho pelos jovens, mas mediante sua forma de organização e produção, busquei identificar elementos produzidos nessas experiências que contribuíssem para uma produção social maior – os saberes e aprendizados significativos na luta das camadas populares, numa perspectiva de contra-cultura, de Educação Popular. O caminho percorrido para elaboração desse estudo situa-se na unidade entre diálogo, reflexão e aprofundamento teórico, numa perspectiva metodológica de inserção nos grupos, observação participante, aplicação de questionários, entrevistas e grupos de discussão e, ainda, a utilização da fotografia, da música e do vídeo como elementos impulsionadores de expressão da subjetividade. Esse caminhar da pesquisa funda-se numa perspectiva teórico-metodológica do tipo etnográfico, que enfatiza a tentativa de compreensão dos elementos que formam o universo cultural, conceitual dos participantes. Os achados revelam que esses grupos, produtores de contra-cultura, situam-se num patamar de exploração e reprodução capitalista pela interação com o mercado organizado por esse sistema, mas ao mesmo tempo colaboram na produção de saberes que, aliados a uma organização e sistematização técnico-científica, pela interação teórico-prática pode contribuir na esfera da contra-hegemonia.

Due to the difficulty of finding registrations about the theme focused – sometimes, due to own lack of these registrations – we have to use as methodological resources some interviews, besides documents, newspapers and pictures that turned out essential elements to a best comprehension of the proposed objective. In this sense, it can be understood that the insertion of the Arabic culture in Floriano city happened in a similar way to that occurred in other Brazilian cities. But, thanks particularly to the presence of the Syrian and Lebanese people in this city, it can be inferred that some aspects of the Arabic influence suffered are different from those occurred in other places, once the immigrants from those countries not only assimilated the regional culture but introduced elements of their own culture, as those relating to food habits and architectural style, only to exemplify. With their natural ability for the commerce they contributed specially to the increase of this activity in Floriano, introducing new commercial practices, including the credit sale modality. Little by little, winning difficulties caused by language and by prejudices, they become respected citizens and assumed public functions, confirming definitely their valuable contribution to the development of Floriano city. / O presente estudo trata da chegada do povo árabe em Floriano, numa tentativa de mostrar como aconteceu o processo de integração sócio-cultural desses imigrantes numa cidade do interior do Piauí, bem como identificar os principais aspectos dessa influência sobre a sociedade, através de uma análise do contexto sócio-histórico-econômico. Devido à dificuldade de encontrar registros sobre o tema enfocado – algumas vezes, devido à própria falta desses registros – tivemos de utilizar como recursos metodológicos algumas entrevistas, além de documentos, jornais e fotografias que se tornaram elementos essenciais para uma melhor compreensão do objetivo proposto. Neste sentido, pode-se entender que a inserção da cultura árabe em Floriano aconteceu de modo semelhante à ocorrida em outras cidades brasileiras. Porém, graças particularmente à presença dos sírios e libaneses, pode-se inferir que nessa cidade alguns aspectos da influência árabe sofrida foram diferentes daqueles ocorridos em outros lugares, uma vez que os imigrantes daqueles países não apenas assimilaram a cultura regional, mas também introduziram elementos de suas próprias culturas, como aqueles relacionados a hábitos alimentares e estilo arquitetônico, apenas para exemplificar. Com sua habilidade natural para o comércio, contribuíram especialmente para o crescimento dessa atividade em Floriano, introduzindo novas práticas comerciais , inclusive a modalidade de venda a prazo. Pouco a pouco, vencendo dificuldades causadas pela língua e pelos preconceitos, tornaram-se cidadãos respeitáveis e assumiram funções públicas importantes, confirmando assim sua valiosa contribuição para o desenvolvimento de Floriano.

Le régulateur PID (Proportionnel-Intégral-Dérivée) est la commande par retour d'état la plus connue. Elle permet d'aborder un bon nombre de problèmes de commande, particulièrement pour des systèmes faiblement non linéaire et dont la performance requise est relativement modeste. En plus, en raison de sa simplicité, la commande PID est largement utilisée en l'industrie. Étant donnés que les méthodes de réglage de la commande PID sont basées sur la linéarisation, la synthèse d'un contrôleur autour d'un point d'équilibre est relativement simple, néanmoins, la performance sera faible dans des modes de fonctionnement loin du point d'équilibre. Pour surmonter ce désavantage, une pratique courante consiste en adapter les gains du PID, procédure connue sous le nom de séquencement de gain (ou gain-scheduling en anglais). Il y a plusieurs désavantages à cette procédure, comme la commutation des gains de la commande et la définition -non triviale- des régions de l'espace d'état dans lesquelles cette commutation aura lieu. Ces deux problèmes se compliquent quand la dynamique est fortement non linéaire. Dans d'autres méthodes, la synthèse de la commande utilise des schémas empiriques, ce qui ne permet pas l'analyse de la stabilité globale du processus. Dans ce contexte, ce travail de thèse a pour objectif de synthétiser des contrôleurs PI, basés sur la passivité, de telle sorte que la stabilité globale du système en boucle fermé soit garantie. L'un des avantages à utiliser la passivité est son attrait intuitif, qui exploite les propriétés physique des systèmes. L'idée centrale dans un système passive est que l'écoulement d'énergie entrante au système provenant de l'extérieur n'est pas inférieur à l'incrément de son énergie de stockage. Par conséquence, ces systèmes ne peuvent pas stocker plus d'énergie que celle fournie, dont la différence correspond à l'énergie dissipée. En introduisant le concept d'énergie, cette méthodologie nous permet de formuler le problème de commande en celui de trouver un système dynamique dont la fonction de stockage d'énergie prend la forme désirée. En incorporant le concept d'énergie cette méthode devient accessible à la communauté de praticiens et permets de fournir des interprétations physique de l'action de commande. Dans cette thèse, une méthodologie constructive de commande PI basée sur la passivité est présentée et motivée par des applications à des systèmes physiques. / One of the best known forms of feeding back a system is through a three-term control law called PID (Proportional-Integral-Derivative) controller. PID controllers are sufficient for many control problems, particularly when process dynamics are not highly nonlinear and the performance requirements are modest. Besides, because of its simple structure, the PID controller is the most adopted control scheme by industry and practitioners, beeing the PI the form mostly employed. Since the PI tuning methods are based on the linearization, commissioning a PI to operate around a single operating point is relatively easy, however, the performance will be below par in wide operating regimes. To overcome this drawback the current practice is to re-tune the gains of the PI controllers based on a linear model of the plant evaluated at various operating points, a procedure known as gain-scheduling. There are several disadvantages of gain-scheduling including the need to switch (or interpolate) the controller gains and the non-trivial definition of the regions in the plants state space where the switching takes place - both problems are exacerbated if the dynamics of the plant is highly nonlinear. In other common scenarios, a little information about the process dynamics or only a "good" linear approximation is taken into account when designing the control design. This impedes to analyse the global stability of the system. In this context, the current thesis work is aimed at the designing of PI controllers, based on the passivity theory, such that the stability of the closed-loop system is guarantied. One of the main advantages of passivity concepts is that they offer a physical and intuitive appeal. The primary idea in passive systems is that the power flowing into the system is not less that the increase of storage. Thus, they cannot store more energy than is supplied to it from the outside, with the difference being the dissipated energy. Thus, introducing the concept of energy, this methodology allows to recast the control problem as finding a dynamical system such that system energy function takes the desired form. Also, with this formulation, the communication between practitioners and control theorists is facilitated, incorporating prior knowledge of the system and providing physical interpretations of the control action. In this thesis, a constructive methodology for deriving PI passivity-based controllers is presented and motivated by the application to physical systems.

The purpose of this thesis is to determine the feasibility of using blockchain to implement proof of location. There has been an increasing demand for a way to create a validated proof of location that is economical, and easy to deploy as well as portable. There are several reasons for an increased demand in this technology including the ever-increasing number of mobile gamers that have been able to spoof their location successfully, the increasing number of on demand package shipments from companies such as Amazon, and the desire to reduce the occurrence of medical errors as well as holding hospitals accountable for their errors. Additional reasons that this technology is gaining popularity and increasing in demand is due the continually increasing number of lost baggage claims that airlines are receiving, as well as insurance companies desire to reduce the number of fraud cases that are related to high-value goods as well as increasing the probability of their recovery. Within the past year, there has been an extensive amount of research as well as work that has been completed to create an irrefutable method of location verification, which will permit a user to be able to create time-stamped documentation validating that they were at a particular location at a certain day and time. Additionally, the user is then permitted to release the information at a later date and time that is convenient for them. This research was completed using a Raspberry Pi 3B, a Raspberry Pi 3B+, two virtual Raspberry Pi’s as well as two virtual servers in which the goal was to download, and setup either Ethereum and/or Tendermint Blockchain on each piece of equipment. After completely synchronizing the blockchain it be used to store the verified location data that been time-stamped. There was a variety of issues that were encountered during the setup and installation of the blockchains on the equipment including overclocking processors, which negatively affected the computational abilities of the devices as well as causing overheating and surges in voltage as well as a variety of software and hardware incompatibilities. These issues when looked at individually appear to not have much of an impact on the results of this research but when combined together it is obvious that they reduced the results that could be obtained. In conclusion, the combination of hardware and software issues when combined with the temperature and voltage issues that were due to the overheating of the processor resulted in several insurmountable issues that could not be overcome. There are several recommendations for continuing this work including presyncing the blockchain using a computer, using a device that has more functionality and computational abilities, connecting a cooling device such as a fan or adding a heat sink, increasing the available power supply, utilizing an externally power hard drive for data storage, recreate this research with the goal in mind of determining what process or application was causing the high processor usage, or creating a distributed system that utilizes both physical and virtual equipment to reduce the amount of work on one type of device.

It examined the relationship between the curriculum, eating practices, daily school life and education about food preferences. Using an ethnographically-based methodology, the study combined qualitative and quantitative approaches. It took place in a public state school in Teresina, Piaui. Students, parents of students, teachers and school workers participated in the study, as well as residents and food sellers in the school vicinity. Data were collected by observation of the school routine, semi-structured interviews based on oral history, and a Questionnaire of Food Consumption Frequency (QFCF). Quantitative data were statistically analyzed using GraphPad Prism to estimate aspects about the education of food preferences and the different types of foods consumed. Qualitative data were examined using principles of Depth Hermeneutics, and consisted of: socio-historical analysis; formal or discursive analysis; and interpretation/reinterpretation. The results indicated that there were two dimensions of education on food preferences: the school curriculum and the concealed curriculum that is expressed in daily school life. The School Allotment, a subject that forms part of the school curriculum, encourages sensory, playful and bonding experiences with foods that are grown at school, and this strategy encourages consumption of healthy food and increases knowledge about the origin of food products. In daily school life, eating practices are particularly important: they not only provide healthy eating models in the four meals offered at the school, but they also prioritize socialization, bonding with food, are a way of practically applying the knowledge that has been acquired about food, and advocate the conscious consumption of food by the students to promote wellness through healthy eating. The identified educational dimensions are part of a formative process of the education of food preferences of students, and stimulate the consumption of vegetables and fruit (which nearly doubled during the course of a school year). There was a more than 50% reduction of weekly consumption of sugars and fried food and a substantial increase in the consumption of white meat. There was also a reduction of canned foods and a gradual minimization of the consumption of red meat, snack foods, animal organs and oils. It was clear that in order to develop the education for food preferences as a formative process that can be constructed at school, it is essential to integrate three areas: education/curriculum, food/nutrition and school environment/community. / Estudo sobre educação do gosto alimentar construído por meio de práticas curriculares e cotidianas de uma escola da rede pública estadual do Piauí, localizada na cidade de Teresina, considerando a relação currículo, prática alimentar, cotidiano escolar e educação para o gosto alimentar. A metodologia teve base etnográfica, conjugando abordagens de natureza qualitativa e quantitativa. Ocorreu em uma escola da rede pública estadual de ensino, em Teresina/PI, da qual participaram alunos e pais de alunos, docentes e funcionários, além de moradores e comerciantes da alimentação da região próxima à escola. A coleta de dados se deu por meio de: observação do cotidiano escolar; entrevistas semi-estruturadas, fundamentadas na História Oral; Questionário de Freqüência do Consumo Alimentar (QFCA). Os dados quantitativos foram pré-analisados, estatisticamente pelo programa GraphPad Prism para estimar aspectos da educação do gosto alimentar, especificando os variados gêneros alimentícios consumidos; os dados qualitativos foram examinados a partir dos fundamentos da Hermenêutica de Profundidade que consta de: análise sócio-histórica; análise formal ou discursiva; e interpretação/ reinterpretação. Os resultados indicam: duas dimensões da educação do gosto alimentar, sendo uma relacionada ao currículo instituído na escola e outra voltada para o currículo oculto, expresso no cotidiano escolar; a disciplina Horta Escolar no currículo da escola estudada, ensejou experiências sensoriais, lúdicas e de vínculo com os alimentos naturalmente cultivados na escola, como estratégia para estimular o consumo de alimentos saudáveis e de ampliação do conhecimento acerca da procedência dos gêneros alimentícios a serem consumidos. No cotidiano escolar, as práticas alimentares se destacam, uma vez que não além de serem apresentados modelos saudáveis de alimentação nas quatro refeições oferecidas da escola, priorizam as socializações realizadas e mediadas pelas práticas alimentares, os vínculos construídos, as aplicações práticas dos conhecimentos estudados acerca da alimentação, preconizando a sensibilização dos alunos para um consumo alimentar consciente e promotor do bem-estar por meio da alimentação saudável. As vertentes identificadas constituem um processo formativo da educação do gosto alimentar nos escolares, fomentando, sobretudo, o consumo de hortaliças e frutas, que quase dobra com a experiência vivida de um ano letivo. Constatou-se a redução de mais de 50% do consumo semanal de açúcares e frituras, com substancial aumento do consumo de carne branca. Houve diminuição da predisposição por alimentos enlatados e progressiva minimização do consumo de carne vermelha, salgadinhos, vísceras e óleos. Enfim, evidenciou-se que para desenvolver a educação do gosto alimentar como processo formativo a ser construído também na escola, é indispensável a integração de três áreas: educação/currículo, alimentação/nutrição e ambiente escolar/comunidade.

This research sought to understand how it happened the historical process of insertion of the capoeira in school spaces and contribute to future studies and subsequent adoption of new sources of research in the field of cultural history in Piauí and Brazil. It’s based on the following problem: How did the historical trajectory of capoeira and the process of schooling of this culture through the narratives of capoeira masters of Teresina-PI? The main objective of the study was Investigate how it happened the historical trajectory of capoeira and the schooling process of this culture from the oral testimonies of capoeira masters of Teresina-PI. The research is qualitative and was based on the historiographical field of Cultural History the main method was the use of narratives memories of capoeira masters in Piauí combined and crossed with several sources several traces and fragments such as texts from newspapers and periodicals images and documents official or unofficial in an attempt to revisit rebuild and give meaning to the past. The masters of capoeira the principal actors of this story identified as holders of knowledge about their history and their educational processes and pioneers in teaching and keeping alive the tradition of this art are Master Caramuru Master Tucano Master Zé Carlos and Master Chocolate selected by representation and authority acquired and recognized in the world of capoeira forged in the struggle of the dynamics of this development. The main experience was to realize the extreme difficulty it is to tell the stories of people without history of marginalized groups and treated as less important in the context of official history a problem that worsens when seeking a story that is told by the subjects themselves who lived and built such a story. This is the case of a history of capoeira in Piauí where officials sources seem not to exist there is no care in registering the story of a culture in which the subjects are ordinary people with no social significance from the standpoint of who represents and can officially say "of the" and "about" the other. The research points to the understanding that capoeira of Piauí was born spontaneously just for the fun and joy of practicing an art of beauty and unusual plasticity a fight that gave respect to its practitioners from a small focus, in early 1970 coming to school by the year 1979 the "invasion" literal to school spaces. The narratives of the masters of capoeiras how that its practice is important in the imaginary of the Teresina city by the vastness of knowledge that characterize it as an instrument of awareness and development of criticality with their songs gestures stories traditions poetry secrets mandingas and magic spells where body and spirit fuse and can never be conceived in separate / A capoeira como manifestação cultural brasileira e fenômeno social que envolve pessoas de classes e grupos sociais diversos criada e desenvolvida pelos escravos e seus descendentes no Brasil é capaz de agregar valores educativos significativos possibilitando um olhar diferenciado sobre a diversidade cultural de nosso povo se constituindo historicamente em um dos instrumentos privilegiados de resistência e estratégia de sobrevivência no bojo das complexas sociedades urbanas brasileiras em que após décadas de perseguições e quase chegando à extinção se reinventou e assume a condição de cultura nacional sendo aceita nos currículos escolares e culminando com sua inscrição do IPHAN como Patrimônio Cultural Imaterial Brasileiro. Esta pesquisa procurou compreender como se deu o processo histórico de inserção da capoeira nos espaços escolares além de contribuir para estudos futuros e posterior adoção de novas fontes de pesquisa no campo da história cultural brasileira e piauiense. Está assentada no seguinte problema: Como se deu a trajetória histórica da capoeira e o processo de escolarização dessa cultura a partir das narrativas de mestres de capoeira de Teresina PI? O objetivo principal do estudo foi Investigar como se deu a trajetória histórica da capoeira e o processo de escolarização dessa cultura a partir dos testemunhos orais de mestres de capoeira de Teresina-PI. A pesquisa de natureza qualitativa se amparou no campo historiográfico da História Cultural privilegiando como metodologia o uso das narrativas das memórias dos mestres de capoeira piauienses combinados e cruzados com diversas fontes diversos traços e fragmentos tais como textos de jornais e de revistas periódicas imagens e documentos oficiais ou não oficiais na tentativa revisitar reconstruir e dar significado a esse passado. Os mestres de capoeira atores principais dessa história identificados como detentores do conhecimento sobre sua história e seu processo de escolarização e pioneiros a ensinar e manter viva a tradição dessa arte são Mestre Caramurú Mestre Tucano Mestre Zé Carlos e Mestre Chocolate selecionados pela representatividade e autoridade adquirida e reconhecida no universo da capoeira forjados nos embates da dinâmica de desenvolvimento dessa cultura. A principal experiência foi perceber a extrema dificuldade que é contar as histórias dos “povos sem história” dos grupos marginalizados e tratados como de menor importância no contexto da história oficial problema que se agrava quando se busca uma história que seja contada pelos próprios sujeitos que vivenciaram e construíram tal história. Esse é o caso de uma história da capoeira no Piauí onde as fontes oficiais parecem não existir não havendo o cuidado em se registrar a história de uma cultura em que os sujeitos são pessoas comuns sem significância social a partir do olhar de quem representa e pode oficialmente falar “do” e “sobre” o outro. A pesquisa aponta para o entendimento de que a capoeira do Piauí nasceu de forma espontânea somente pelo prazer e a alegria de se praticar uma arte de beleza e plasticidade incomuns uma luta que dava respeito a seus praticantes a partir de um pequeno foco no início dos anos de 1970 chegando até a escola por volta do ano de 1979 pela “invasão” literal aos espaços escolares. As narrativas dos mestres de capoeira revelam que sua prática é importante no imaginário teresinense pela vastidão de saberes que a caracterizam enquanto instrumento de conscientização e desenvolvimento da criticidade com suas cantigas gestualidades histórias tradições poesias segredos mandingas e magias em que corpo e espírito se fundem e jamais podem ser concebidos em separados

To this end, we have taken the perspective of dialectical, historical materialism. The thread of our analysis is processed methodologically in the intertwining of written and oral sources. For this, we took a qualitative approach compounded of bibliographic and field researches, where we identified and inserted our research subjects through the Oral History. Seeking to meet the goals of this research, we collected data about the professional qualification courses attended by the members, pointing out, in our reflections, the contradictions present in this movement. We realized that, although many, the courses offered by SEBRAE and UFPI were superficial and offered a fragmented knowledge to those who were motivated to attend such courses. Despite this superficiality, this was a milestone for the organization of the workers in the sector, who point their participation as the motivator for the creation of the first local cooperative of tourism guides, the Cooperativa de Condutores e Guias de Turismo de Ilha Grande (Cooperative of Ecotourism Guides of Ilha Grande) – COOPERCIG - that had a short duration and was later disarticulated and restructured, now as ILHAECOTUR. We realized that the offering of courses, for been received passively by and articulated in absentia of the participants, helps the process of alienation and reification of workers in relation to their activity, furthermore, it has become an obstacle to greater coordination among workers acting in this sector, because there is a dispute between workers "skilled" and "unskilled", which contributes only to further exploration of both by capitalist instances which make the tourism in Parnaíba Delta their main product. Therefore, it is concluded that the effects of realization of qualification courses among members of ILHAECOTUR are mostly negative, for they provide to workers a minimum and fragmented knowledge, based on the complexity that involves tourism, generating a training focused on meeting the capitalist needs, making difficult the awareness of these workers to their importance in the development of tourism in the region they inhabit. / A presente pesquisa teve como propósito investigar as experiências dos cursos de qualificação profissional na atividade laboral dos integrantes da Associação de Condutores de Ecoturismo de Ilha Grande – ILHAECOTUR – Piauí, Brasil, que vendem sua força de trabalho para suprir as suas necessidades na região do Delta do Parnaíba em sua extensão piauiense. Para tanto, me apropriei da perspectiva do materialismo histórico dialético. O fio condutor de nossa analise se processa metodologicamente no entrelaçamento de fontes escritas e orais. Para isso tomei uma abordagem qualitativa composta com pesquisas bibliográficas e de campo onde identifiquei e inseri meus sujeitos de pesquisa através da História Oral. Buscando atender aos objetivos da pesquisa, fiz um levantamento dos cursos de qualificação profissional realizados pelos associados apontando em minhas reflexões as contradições presentes nesse movimento. Percebi que apesar de diversos, os cursos ofertados pelo SEBRAE e pela UFPI eram superficiais e ofereciam um conhecimento fragmentado aos que se motivavam a cursa-los. Apesar dessa superficialidade, esse foi um marco para a organização dos trabalhadores do setor que apontam a participação nos mesmos como o motivador para a criação da primeira cooperativa voltada aos condutores de turismo do local, a Cooperativa de Condutores e Guias de Turismo de Ilha Grande – COOPERCIG que teve um curto período de duração e foi posteriormente desarticulada e reestruturada, agora como ILHAECOTUR. Percebi que a oferta dos cursos por ser recebida de forma passiva e articulada a revelia dos interesses dos mesmos colabora com o processo de estranhamento e reificação dos trabalhadores em relação a sua atividade, além disso, se tornou um entrave para uma maior articulação entre os trabalhadores que atuam no setor, pois existe uma disputa entre trabalhadores “qualificados” e “não qualificados” o que colabora apenas com uma maior exploração de ambos pelas instancias capitalistas que fazem do turismo no Delta do Parnaíba seu principal produto. Conclui-se, portanto que os reflexos da realização dos cursos de qualificação entre os membros da ILHAECOTUR são em maioria negativos, pois proporcionam aos trabalhadores um conhecimento mínimo e fragmentado tendo por base a complexidade que envolve o turismo gerando uma formação voltada a suprir as necessidades capitalistas dificultando a tomada de consciência desses trabalhadores para sua importância no desenvolvimento da atividade turística na região que habitam.

Master of Science / Department of Computing and Information Sciences / Mitchell Neilsen / The Raspberry Pi is a versatile computer for its size and cost. The research done in this project will explore how well the Raspberry Pi performs in a clustered environment. Using the Pi as the components of a Beowulf cluster will produce an inexpensive and small cluster. The research includes constructing the cluster as well as running a computationally intensive program called OpenFOAM. The Pi cluster's performance will be measured using the High Performance Linpack benchmark. The Raspberry Pi is already used for basic computer science education and in a cluster can also be used to promote more advanced concepts such as parallel programming and high performance computing. The inexpensive cost of the cluster combined with its compact sizing would make a viable alternative for educational facilities that don't own, or can't spare, their own production clusters for educational use. This also could see use with researchers running computationally intensive programs locally on a personal cluster. The cluster produced was an eight node Pi cluster that generates up to 2.365 GFLOPS.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Quartz crystal is an important electronic element in the field of communication systems, computer systems, etc. It is important to precisely measure the frequency of quartz crystal unit for manufacturing. The Pi-network transmission system recommended by International Electrotechnical Commission (IEC) is generally acknowledged as a measurement technique. However it needs a precise frequency source. The frequency source must be calibrated within a regular period in the process of manufacturing. Frequency counters, time internal counters, phase comparisons, which are the most common frequency calibrations, are introduced in the paper. Nowadays GPS has also become the primary system for frequency calibration. GPS receivers provide 1 PPS (Pulse Per Second) with accuracy < 100 nanoseconds to UTC under normal conditions. Motorola UT Oncore timing GPS with time accuracy < 50ns (1 sigma) uses time RAIM algorithm to ensure the validity and reliability of measurements. The comparison between the precise 1PPS and local reference is implemented. And the phase differences are logged and read by computer. According to the values, the frequency output of DDS is coordinated. In order to reduce the phase ambiguity, local reference is divided before comparison. The calibration can be implemented at any time by GPS. Block diagrams of calibration are presented in this paper.
