With the disorganized decentralization occurred in Brazil after the 1988 Constitution, municipalities have risen to the level of federal entities. This phenomenon became known as "municipalism" also brought some negative effects such as low capacity financial, economic and political of these entities. In the face of this reality , the municipalities sought in models of collaborative features to address public policy issues ultrarregionais, one of these models are the Public Consortia. Characterized as the organization of all federal entities that aim to solve public policy implementation alone that they could not, or spend great resources for such. This reality of the municipalities have an aggravating factor when looking at the situation in Metropolitan Regions (MRs). This is because the RMs has a historical process of formation that does not encourage cooperation, since that were created top-down during the military regime. Furthermore, the metropolitan municipalities have significant power asymmetries, localist vision, rigidity earmarked revenues, different scenarios conurbation, difficulty standardization of concepts and others that contribute to the vision of low cooperation of these metropolitan areas. Thus, the problem of this work is in the presence of collaborative arrangements, such as the Public Consortia in metropolitan areas, which are seen as areas of low cooperation. To elucidate this research was used for analysis the cases of CONDIAM/PB and Consórcio Grande Recife/PE, because they are apparently antagonistic, but with some points of similarity. The cases has as foundation the Theory of Common Resources, which provides the possibility of collective action through the initiative of individuals. This theory has as its methodology for analyzing the picture IAD Framework, which proposes its analysis based on three axes: external variables, the arena of action and results. The nature of the method of this research was classified as exploratory and descriptive. For the stage of date analysis, was used the method of document analysis and content, Further than of separation of the cases according to theur especificities. At the end of the study, noted that the CONDIAM/PB was a strategy of municipal government of Joao Pessoa to attract funds from the Federal Government for the purpose of to build a landfill, and over the years the ideology of cooperation was left aside, the prevailing view localist municipalities. In the case of Consórcio Grande Recife/PE, members act with some degree of cooperation, especially the collaborative aspect of the region, however, still prevails with greater strength the power of the state of Pernambuco in the decisions and paths of the consortium. Thus, was conclude that the Public Consortia analyzed are an experience of collaborative arrangement, from the initiative of members, as the theory of common resources says, but has not actually signed as a practice of collective action to overcome the dilemmas faced by metropolitan areas

The research investigates the acting and the importance for the users of the public squares located predominantly in residential areas. It presents the results of the posoccupation evaluations accomplished in three squares, whose physical, environmental characteristics, equipments and fumitures are different in its qualities and amounts, taking in consideration aspects related to the users' physical and psychological comfort and of the inhabitants of the I spill. The collection of data involved physical risings and of files, observations behavious, application of questionnaires and interviews, analyzed qualitative as quantitatively so much for a larger precision and validity of the investigation. The results were obtained through the relationship among the users' perception the environmental attributes and the different levels of apropriation/use of the studied places. They indicate that the aspects composicionais of physical order of the space affects the type and the intensity of use of the squares intimately, contributing positive or negatively for its valor. It is evidenced like this, that the low freqüentation of the public squares of Natal, is due mainly to referring aspects to the physical quality and the amount of the fumitures and urban equipments. It is ended that the investments and the physical planning of these public spaces should be based in the real knowledge of the aspirations of the population objective, in way to allow its largest use and valor

Study public space is studying the city and its dynamics through a representation point. The changes that are observed in these spaces and in the relations established there, or with it, are related to changes that occurred in the city as a whole, in the urban way of living. Study public space allied to urban sociability permits an even better focus on this relation between people in these spaces and with the spaces and in the consequences and fragile aspects this relation can impose to people and cities. This work is aimed towards this relation between public space and urban sociability. Through a conceptual/theoretical discussion aims, specifically, comprehend how to establish and what is the relation between urban space and urban sociability (appropriation/perception of place, tendencies of seclusion), from an isolated analysis of each one of these themes in the contemporaneous city. The Brazilian public space has peculiar characteristics, arising from its historical process of construction, also influenced by the public sphere fragile construction that permeates it, as well as more recent variables such as the sensation of insecurity and commodification of these places. The urban sociability influences and is influenced along all this process of significance and reframing of the public space. The conceptual discussion about each isolate variable provides the necessary coverage for discussion and analysis of the relation between them and the consequence of this relation in the city, such as the notation of relevant experiences of this process of revaluation of the public space. The hereby search is not through a path to reestablish the relation as it already existed, but also for an understanding of the dynamic as is established today and for existing possibilities for maintenance and appreciation of the relation between people and the city by believing in its importance to urban life

This work aims to analyze and evaluate the Urban furniture designed to public areas according to the Revitalization planning for Rio Grande do Norte coastland, defining visual relations among urban elements in the landscape of revitalized public urban areas with cultural, paisagistic and touristic values and the design process used for developing urban furniture to those areas, observing the incoming consequences use to that process in a specific urban context which alters use, functions, cultural images as well as social values attributed to each particular place. Environmental perceptions, legibility of local cultural references and their representation through the design of urban elements, act in a positive or negative manner over the inhabitants cognition process of some particular revitalized area, determining new use and attributions to those areas. Designs for coastal urban interventions try excessively to standardize technical media, construction materials and planning configurations, creating artificial sceneries that segregates users, imposing new structures and usage, generating, consequently, the so called non-places and burlesque regionalism. The research is divided into 4 chapters: 1) Theoretical support (Industrial design; Urban furniture; Public urban spaces; Urban image and environmental perception; Urban occupation and interventions in coastland areas); 2) Methodological procedures and data collection; 3) Analysis of Rio Grande do Norte coastal areas and their urban interventions; 4) Final considerations and Industrial Design contributions to the subject

This master dissertation presents the study and implementation of inteligent algorithms to monitor the measurement of sensors involved in natural gas custody transfer processes. To create these algoritmhs Artificial Neural Networks are investigated because they have some particular properties, such as: learning, adaptation, prediction. A neural predictor is developed to reproduce the sensor output dynamic behavior, in such a way that its output is compared to the real sensor output. A recurrent neural network is used for this purpose, because of its ability to deal with dynamic information. The real sensor output and the estimated predictor output work as the basis for the creation of possible sensor fault detection and diagnosis strategies. Two competitive neural network architectures are investigated and their capabilities are used to classify different kinds of faults. The prediction algorithm and the fault detection classification strategies, as well as the obtained results, are presented

A problemática atual da urbanização coloca questões delicadas referentes ao seu ritmo de crescimento, sua relação com o desenvolvimento econômico, o aparecimento de novas formas urbanas e sua relação com as novas maneiras de articulação capitalista. A compreensão espacial do lazer nas cidades apresenta-se, assim, como tema de grande importância para as sociedades contemporâneas. O interesse e a importância de tratar esse tema na cidade do Natal - enfocando-se a distribuição dos espaços públicos de lazer nos diversos bairros e sua utilização pelos seus habitantes - justifica-se pelo fato dessa capital apresentar um crescimento populacional surpreendente nos últimos anos, tendo uma expansão urbana desordenada que se reflete na carência de infra-estrutura urbana e numa forte segregação espacial. Foram feitas a verificação da disponibilidade de espaços públicos de lazer nos bairros e a identificação dos diversos fatores que interferem na utilização desses espaços, visando contribuir para a compreensão do fenômeno do lazer urbano, bem como, para o aprofundamento da discussão acerca da função social desses, que possibilite montar estratégias para a utilização de forma democrática desses espaços nas cidades. Para tanto foi necessária uma articulação teórica das questões peltinentes ao espaço urbano e ao lazer, que formam uma área epistemológica de interseção quando trata das questões referentes ao direito à cidadania, onde está contemplado o direito à cidade (á moradia e ao seu entomo). Os dados para que caracterizaram as vivências do lazer nos espaços públicos da cidade foram levantados em três fontes: nos documentos (plano diretor da cidade, planos de políticas públicas entre outros), nas entrevistas com a comunidade e nas observações diretas dos espaços de manifestações do lazer. A análise aponta que existe uma distribuição irregular dos espaços públicos de lazer, por bairro e Região Administrativa da cidade do Natal que apresenta relação com a segregação espacial por classe, existente na cidade, fruto da dinâmica econômica e práticas sociais aqui existentes. Constata-se ainda que a camada desprovida desses equipamentos de lazer não age espontaneamente, nem através de seus representantes e mandatários institucionais, em prol da distribuição de oportunidades nesses campos, possibilitando que a segregação continue em círculos viciosos, pois a própria segregação dificulta o encontro, a percepção das diferenças e o conflito, que podem ser resgatados numa nova forma de organização do cotidiano

The purpose of this dissertation is to analyze the role of Public Powers in the enforcement of fundamental social rights, according to the principle of prohibition to social regression. The Federal Constitution of Brazil, situated in a position normative hierarchical superior, disciplines the legal and political process of the country, determining how Public Powers (Legislative, Executive and Judiciary) should act to enforce fundamental rights (social). Thus, features a cast of fundamental rights that aim to ensure social justice, highlighting the concern to ensure social values aimed at reducing social inequalities. The will of the state should be prevented by controlling the constitutionality of measures which restrict fundamental social rights, assuming the principle of human dignity, pillar of Social and Democratic State of Right, a dual role in the brazilian legal system, acting as the presupposition of jurisdictional control of the constitutionality of restrictive acts and as supervisory of omission or insufficient action of the State in the fulfillment of their fundamental duties. The constitutional determinations remove from the legislator the option to create or not the law that prints effectiveness to the social rights, as well as from the Executive the option of to execute or not rules directed at realization of the constitutional parameters, and Judiciary to behave or not in accordance with the Constitution, being given to the Powers only the arbitrariness of "how" to do, so that all functions performed by public actors to use the Constitution as a repository of the foundational values of the collectivity. Any situation that does not conform the principle of proportionality in relation to the enforcement of fundamental rights, especially the social, represents an unacceptable social regression unconstitutional. The constitutional rules and principles postulated by the realization of the rights, freedoms and guarantees of the human person, acting the principle of prohibition to social regression to regulate a concrete situation, whenever it is intended to change, reducing or deleting, the content of a social right. This paper of limit of state action serves to provide to the society legal security and protection of trust, ensuring the core of every social right. This should be effected to be sheltered the existential minimum, as a guarantee of the inviolability of human life, respecting the constitutional will, not falling into social regression

With a focus on the need for effectiveness of fundamental rights of persons with disabilities, this dissertation held a scientific research to analyze the degree of implementation of reservation of positions and public jobs to people with disabilities in the Brazilian State, because the 1988 Federal Constitution expressly determined such a reservation in your article 37, VIII. Highlight that this subject is enough evidence, given the large number of open public competition in recent years in Brazil, as well as recent proposals to grant equal rights to blacks (Bill nº 6,738/2013). In addition, the wording the constitutional device comes fomenting heated discussions on the subject, which are flowing on the doors of the judiciary and are spicy because such protection Microsystem vulnerable group has several gaps in the regulation of this policy. However, the research produced, unlike other related theme, does not address the problem of inefficiency in its constitutional theory, that is, abstractly, but also focuses on a specific analysis of this ineffectiveness within Brazilian society, so that research based on a bibliographical analysis, plus a study case law, at the national level, as well as in field research, while case study, focusing on the technique of the analysis of everyday life, because it was believed that the degree of realization of the constitutional norm debated is not yet a satisfactory degree of effectiveness. Soon, the methodological procedures chosen confirmed such a hypothesis and contributed to the study of realization of the fundamental right to work of people with disabilities in Brazil, the light of a Constitutional State, proposing a constitutionally appropriate model the greater effectiveness of the constitutional norm studied

This paper aims to measure the degree of efficiency in the allocation of public resources in education from the FUNDEB in elementary education in the towns of Rio Grande do Norte in 2007 and 2011. To do so, we must determine to evaluate the efficiency in the allocation of public resources in municipal education in the early and last grades of elementary education; verify that the towns that achieved higher levels of efficiency that were allocated the largest volumes of resources in primary education and analyze which towns reached the worst and the best levels of efficiency in the allocation of public resources in education. This is on the assumption that the relation between the educational policies of local governments and concern for efficiency in the allocation of resources in education is limited only to increase spending on education. It is intended from the model of Data Envelopment analysis, (DEA), with Variable Returns to Scale (VRS), estimate the efficiency of spending on education and municipal pubic purging the problem of outliers. Estimations show that the municipalities of Rio Grande do Norte do not allocate their resources in public elementary education efficiently

The industrial automation is directly linked to the development of information tecnology. Better hardware solutions, as well as improvements in software development methodologies make possible the rapid growth of the productive process control. In this thesis, we propose an architecture that will allow the joining of two technologies in hardware (industrial network) and software field (multiagent systems). The objective of this proposal is to join those technologies in a multiagent architecture to allow control strategies implementations in to field devices. With this, we intend develop an agents architecture to detect and solve problems which may occur in the industrial network environment. Our work ally machine learning with industrial context, become proposed multiagent architecture adaptable to unfamiliar or unexpected production environment. We used neural networks and presented an allocation strategies of these networks in industrial network field devices. With this we intend to improve decision support at plant level and allow operations human intervention independent

This work presents a set of intelligent algorithms with the purpose of correcting calibration errors in sensors and reducting the periodicity of their calibrations. Such algorithms were designed using Artificial Neural Networks due to its great capacity of learning, adaptation and function approximation. Two approaches willbe shown, the firstone uses Multilayer Perceptron Networks to approximate the many shapes of the calibration curve of a sensor which discalibrates in different time points. This approach requires the knowledge of the sensor s functioning time, but this information is not always available. To overcome this need, another approach using Recurrent Neural Networks was proposed. The Recurrent Neural Networks have a great capacity of learning the dynamics of a system to which it was trained, so they can learn the dynamics of a sensor s discalibration. Knowingthe sensor s functioning time or its discalibration dynamics, it is possible to determine how much a sensor is discalibrated and correct its measured value, providing then, a more exact measurement. The algorithms proposed in this work can be implemented in a Foundation Fieldbus industrial network environment, which has a good capacity of device programming through its function blocks, making it possible to have them applied to the measurement process

On this paper, it is made a comparative analysis among a controller fuzzy coupled to a PID neural adjusted by an AGwith several traditional control techniques, all of them applied in a system of tanks (I model of 2nd order non lineal). With the objective of making possible the techniques involved in the comparative analysis and to validate the control to be compared, simulations were accomplished of some control techniques (conventional PID adjusted by GA, Neural PID (PIDN) adjusted by GA, Fuzzy PI, two Fuzzy attached to a PID Neural adjusted by GA and Fuzzy MISO (3 inputs) attached to a PIDN adjusted by GA) to have some comparative effects with the considered controller. After doing, all the tests, some control structures were elected from all the tested techniques on the simulating stage (conventional PID adjusted by GA, Fuzzy PI, two Fuzzy attached to a PIDN adjusted by GA and Fuzzy MISO (3 inputs) attached to a PIDN adjusted by GA), to be implemented at the real system of tanks. These two kinds of operation, both the simulated and the real, were very important to achieve a solid basement in order to establish the comparisons and the possible validations show by the results

Simulations based on cognitively rich agents can become a very intensive computing task, especially when the simulated environment represents a complex system. This situation becomes worse when time constraints are present. This kind of simulations would benefit from a mechanism that improves the way agents perceive and react to changes in these types of environments. In other worlds, an approach to improve the efficiency (performance and accuracy) in the decision process of autonomous agents in a simulation would be useful. In complex environments, and full of variables, it is possible that not every information available to the agent is necessary for its decision-making process, depending indeed, on the task being performed. Then, the agent would need to filter the coming perceptions in the same as we do with our attentions focus. By using a focus of attention, only the information that really matters to the agent running context are perceived (cognitively processed), which can improve the decision making process. The architecture proposed herein presents a structure for cognitive agents divided into two parts: 1) the main part contains the reasoning / planning process, knowledge and affective state of the agent, and 2) a set of behaviors that are triggered by planning in order to achieve the agent s goals. Each of these behaviors has a runtime dynamically adjustable focus of attention, adjusted according to the variation of the agent s affective state. The focus of each behavior is divided into a qualitative focus, which is responsible for the quality of the perceived data, and a quantitative focus, which is responsible for the quantity of the perceived data. Thus, the behavior will be able to filter the information sent by the agent sensors, and build a list of perceived elements containing only the information necessary to the agent, according to the context of the behavior that is currently running. Based on the human attention focus, the agent is also dotted of a affective state. The agent s affective state is based on theories of human emotion, mood and personality. This model serves as a basis for the mechanism of continuous adjustment of the agent s attention focus, both the qualitative and the quantative focus. With this mechanism, the agent can adjust its focus of attention during the execution of the behavior, in order to become more efficient in the face of environmental changes. The proposed architecture can be used in a very flexibly way. The focus of attention can work in a fixed way (neither the qualitative focus nor the quantitaive focus one changes), as well as using different combinations for the qualitative and quantitative foci variation. The architecture was built on a platform for BDI agents, but its design allows it to be used in any other type of agents, since the implementation is made only in the perception level layer of the agent. In order to evaluate the contribution proposed in this work, an extensive series of experiments were conducted on an agent-based simulation over a fire-growing scenario. In the simulations, the agents using the architecture proposed in this work are compared with similar agents (with the same reasoning model), but able to process all the information sent by the environment. Intuitively, it is expected that the omniscient agent would be more efficient, since they can handle all the possible option before taking a decision. However, the experiments showed that attention-focus based agents can be as efficient as the omniscient ones, with the advantage of being able to solve the same problems in a significantly reduced time. Thus, the experiments indicate the efficiency of the proposed architecture
