A utilização de sistemas embutidos distribuídos em diversas áreas como a robótica, automação industrial e aviónica tem vindo a generalizar-se no decorrer dos últimos anos. Este tipo de sistemas são compostos por vários nós, geralmente designados por sistemas embutidos. Estes nós encontram-se interligados através de uma infra-estrutura de comunicação de forma a possibilitar a troca de informação entre eles de maneira a concretizar um objetivo comum. Por norma os sistemas embutidos distribuídos apresentam requisitos temporais bastante exigentes. A tecnologia Ethernet e os protocolos de comunicação, com propriedades de tempo real, desenvolvidos para esta não conseguem associar de uma forma eficaz os requisitos temporais das aplicações de tempo real aos requisitos Quality of Service (QoS) dos diferentes tipos de tráfego. O switch Hard Real-Time Ethernet Switching (HaRTES) foi desenvolvido e implementado com o objetivo de solucionar estes problemas devido às suas capacidades como a sincronização de fluxos diferentes e gestão de diferentes tipos de tráfego. Esta dissertação apresenta a adaptação de um sistemas físico de modo a possibilitar a demonstração do correto funcionamento do sistema de comunicação, que será desenvolvido e implementado, utilizando um switch HaRTES como o elemento responsável pela troca de informação na rede entre os nós. O desempenho da arquitetura de rede desenvolvida será também testada e avaliada.

"[…]. A aplicação de técnicas estatísticas na análise de problemas económicos, em que é necessário testar hipóteses sobre as relações económicas e prever mudanças nos valores de variáveis relevantes, tem tido uma importância crescente. Algumas relações teóricas entre variáveis económicas podem ser expressas usando modelos matemáticos, cujos parâmetros podem ser estimados usando métodos estatísticos. […].Os gestores de empresas são frequentemente confrontados com processos de tomada de decisão, pelo que a posse de conhecimentos de Estatística e o domínio de software que permita a gestão de informação em tempo real é uma mais-valia, principalmente na análise de situações que incluam cenários de incerteza. Nessa perspetiva, os gestores e todos os outros tomadores de decisão têm de ser capazes de entender a informação e usá-la eficazmente, não esquecendo que “se gerir é tomar decisões, gerir bem é tomar boas decisões".

The IT capability is a organizational ability to perform activities of this role more effectively and an important mechanism in creating value. Its building process (stages of creation and development) occurs through management initiatives for improvement in the performance of their activities, using human resources and IT assets complementary responsible for the evolution of their organizational routines. This research deals with the IT capabilities related to SIG (integrated institutional management systems), built and deployed in UFRN (Universidade Federal do Rio Grande do Norte) to realization and control of administrative, academic and human resources activities. Since 2009, through cooperative agreements with federal and educational institutions of direct administration, UFRN has supported the implementation of these systems, currently involving more than 30 institutions. The present study aims to understand how IT capabilities, relevant in the design, implementation and dissemination of SIG, were built over time. This is a single case study of qualitative and longitudinal nature, performed by capturing, coding and analysis from secondary data and from semi-structured interviews conducted primarily with members of Superintenência de Informática, organizational unit responsible for SIG systems in UFRN. As a result, the technical, of internal relationship and external cooperation capabilities were identified as relevant in the successful trajectory of SIG systems, which have evolved in different ways. The technical capacity, initiated in 2004, toured the stages of creation and development until it reached the stage of stability in 2013, due to technological limits. Regarding the internal relationship capability, begun in 2006, it toured the stages of creation and development, having extended its scope of activities in 2009, being in development since then. Unlike the standard life cycle observed in the literature, the external cooperation capability was initiated by an intensity of initiatives and developments in the routines in 2009, which were decreasing to cease in 2013 in order to stabilize the technological infrastructure already created for cooperative institutions. It was still identified the start of cooperation in 2009 as an important event selection, responsible for changing or creating trajectories of evolution in all three capacities. The most frequent improvements initiatives were of organizational nature and the internal planning activity has been transformed over the routines of the three capabilities. Important resources and complementary assets have been identified as important for the realization of initiatives, such as human resources technical knowledge to the technical capabilities and external cooperation, and business knowledge, for all of them, as well as IT assets: the iproject application for control of development processes, and the document repository wiki. All these resources and complementary assets grew along the capacities, demonstrating its strategic value to SINFO/UFRN

To implement policies and plans at the tourist sector involve disposition to the establishment of parceries among government and private initiative, space to the action of studious, researchers and professionals of several areas of knowledge and formation, able of to give new courses no only at the tourism, but to the economy how a every, seen which the tourism had a effect multiplicator, reaching 52 sectors of the economy. At this sense, the Brazil came pruning for a new phase of politic actuation at the touristy activity. Until the year 2002, the tourism politic in the Brazil no had detail, because herself treated of isolated actions and many without continuity. However, at to start 2003, several actions were developed in order to contribute for the national touristy planning. The principal was the creation of Ministério do Turismo, accompanied of the formulation and implementation of the Plano Nacional do Turismo (2003/2007). This work pretend to understand the implementation at the Rio Grande do Norte of the model of participative administration extolled by Plano Nacional do Turismo. The your centre detail the action of the Conselho Estadual de Turismo do Rio Grande do Norte (CONETUR), to promote the participation at the tourism public policies. The bibliographical research contemplated diverse sources in order to compile knowledge of credential authors in the quarrel of inherent subjects to the participation and to the tourism public policies, especially at the Brazil. A qualitative perspective the case study was adapted as research method and for attainment of the data interviews with the members of the Conselho had been carried through beyond consultation the referring documents the dynamics of functioning of the Conselho. The principal actuations of the CONETUR, the directives tourism public policies already made and directed to implementation, the type of participation at made decision, the principal difficulties of the implementation of the participative administration model of the Plano Nacional do Turismo and the degree of participation of the members of the Conselho at the reunions had been identified. The results had shown that exist some difficulties at the implementation of the participation at the Conselho Estadual de Turismo do Rio Grande do Norte, knowledge of the Conselheiros of CONETUR function, the presence of bodies which doesn t directly connected at the touristy activity; the absence of time of the Conselheiros to be presents at reunions; the discontinuity of the presidency of the Conselho; among others. So, the CONETUR show himself how a Conselho with participative characteristics, but with some adapted needs.

Em tempos de grandes argumentações em torno da globalização, temos vindo a assistir, em Portugal, e um pouco por todo o mundo, à discussão sobre a autonomia dos indivíduos e das instituições. Ao mesmo tempo, discutem-se as vantagens e desvantagens, não só dessa autonomia, mas também de uma maior desconcentração e descentralização por parte do Estado, em geral, e dentro de cada uma das suas unidades orgânicas. O Ministério da Educação português não tem estado alheio a esta discussão e tem produzido legislação no sentido de as concretizar. O presente estudo alinha-se nestas preocupações e tenta determinar se às escolas públicas enquanto instituições estatais, garante do ensino público, tem sido outorgada essa autonomia e qual o seu grau de exercício. Em simultâneo visa aferir das dificuldades que esse processo descentralizador tem vindo experimentar.

The Federal Institution for Education, Science and Technology, in its historical path, has been living different changes. The transformations occurred along the way have been determined by coercive forces from the institutional environment, which has became more and more broad and complex throughout the time, obtaining diverse characteristics and new elements such as non institutional factors1 which started to contribute with the other changes. In this context, this work aims to study the isomorphic practices of the managers in the institutional changes process of the IFRN in 1998 and 2008, as of a theoretical coevolutionary perspective (CHILD; RODRIGUES; LEWIN; CARROL; VOLBERDA, 2003). This theory brings a new point of view for the organization analysis to the organizational studies, since it offers a non deterministic and non linear lection of the evolution process, which means, a coevolution. Thus, the organizations and their institutional and non institutional environment auto evolve, auto organize and auto reproduce. Therefore, the institutional and non institutional factors of the macro environment keep a continuous interdependence relationship with the organizations. For the means of this study, it is important to understand that is impossible to comprehend the object, the isomorphic practices, without considering that the previous institutional changes and its evolutions, its continuations and discontinuations, important in the coevolution process. As such, to call upon the institutional historical track is a fundamental aspect to materialize this study, for the recursive movement is indeed present in the coevolution. Another important point to make this research effective is that it is not possible to abdicate from the hologramatic view2 of this study, which considers the object, the isomorphic practices, part of the whole and this whole is also in the parts, therefore it is impossible to comprehend the object of study outside the context where it belongs. With this, as of the objective previously proposed, it is necessary to describe the characteristics of coevolution of the institutional changes related in 1998 and 2008; analyze the dynamic of the isomorphic mechanisms in its respective institutional change process; and describe the lessons learned which the isomorphic practices left to the IFRN, regarding its benefits and difficulties. All these transformations happened through coercive forces3 of the institutional environment. As of the Nineties, these forces became stronger, the environment became broader and more complex, with the emergency of new environmental factors. This study proposed to study the managing process and its practices, related to the micro environment, although it is required to articulate these actions, the demands and requirements from the macro environment. To make this research effective, semi structured interviews have been conducted with the managers who participated in both institutional change processes. In the results analysis, it has been possible to verify the particularity of each change, the one from 1998 with a strong normative action of the managers against coercive forces from the government for the search of recognition and the institutional legitimation and the one in 2008, which has been characterized by the normative action by managers in agreement with the coercive forces from the government, in favor of the government policy for the technological professional education. However, the results analysis it is possible to notice the evidence of a belonging feeling from the interviewed managers

Uma das áreas de aplicação da optimização é a Engenharia Biomédica, pois a optimização intervém no estudo de próteses e implantes, na reconstrução tomográfica, na mecânica experimental, entre outras aplicações. Este projecto tem como principal objectivo a criação de um novo programa de marcação de exames médicos a fim de minimizar o tempo de espera na realização dos mesmos. É efectuada uma breve referência à teoria da optimização bem como à optimização linear e não-linear, aos algoritmos genéticos, que foram usados para a realização deste trabalho. É também apresentado um caso de estudo, formulado como um problema de optimização não linear com restrições. Com este estudo verificou-se que o escalonamento de exames médicos nunca poderá ser optimizado a 100por cento devido à quantidade de variáveis existentes, sendo que algumas delas não são passíveis de prever com antecedência.
