Influência da escala na análise morfométrica de microbacias hidrográficas

In order to verify the different scales in physical analysis of watersheds, the geomorphic quantitative analysis was done to distinguish homogeneous areas within this land unit. The variables studied were the dimensions, drainage pattern and relief characteristics. The study area is the watershed of the Corrego da Cachoeira, São Paulo State, Brazil. The cartographic scale 1: 50000 (IBGE) and 1: 10000 (IGC) were used to delineate the drainage network and study the morphometric characteristics. The watershed is characterized as an exoreic, fluvial drainage with consequent streams and drainage pattern. The values of the drainage density, frequency of rivers and the ratio of bifurcation are considered low, indicating the formation of the soil on permeable rock. The low values suggested a watershed with relatively mild relief. The detail of the cartography mapping analysed with field study data showed higher values of hydrological compartments and length of the drainage network, reflecting changes in the results obtained on the physical variables analysed.

SAMVC sistema de autoria de museus virtuais colaborativos

The use of graphical objects three-dimensional (3D) multimedia applications is gaining more space in the media. Networks with high transmission rates, computers with large processing and graphics boost and popularize such three-dimensional applications. The areas of 3D applications ranging from military applications, entertainment applications geared up for education. Within the applications related to education, we highlight the applications that create virtual copies of cultural spaces such as museums. Through this copy, you can virtually visit a museum, see other users, communicate, exchange information on works, etc. Thereby allowing the visit museums physically distant remote users. A major problem of such virtual environments is its update. By dealing with various media (text, images, sounds, and 3D models), its subsequent handling and update on a virtual environment requires staff with specialized knowledge. Speaking of museums, they hardly have people on your team with this profile. Inside the GT-MV (Grupo de Trabalho de Museus Virtuais), funded by RNP (Rede Nacional de Ensino e Pesquisa) propose a portal for registration, amendment and seen collaborative virtual museums of Brazil. The update, be it related to work or physical space, a system with a national scale like this, would be impossible if done only by the project team. Within this scenario, we propose the modeling and implementation of a tool that allows editing of virtual spaces in an easy and intuitive as compared with available tools. Within the context of GT-MV, we apply the SAMVC (Sistema de Autoria de Museus Virtuais Colaborativos) to museums where curators build the museum from a 3D floor plan (2D). The system, from these twodimensional information, recreates the equivalent in three dimensions. With this, through little or no training, team members from each museum may be responsible for updating the system

Desenvolvimento de um Sistema de Visão Global para uma Frota de Mini-Robôs Móveis

Navigation based on visual feedback for robots, working in a closed environment, can be obtained settling a camera in each robot (local vision system). However, this solution requests a camera and capacity of local processing for each robot. When possible, a global vision system is a cheapest solution for this problem. In this case, one or a little amount of cameras, covering all the workspace, can be shared by the entire team of robots, saving the cost of a great amount of cameras and the associated processing hardware needed in a local vision system. This work presents the implementation and experimental results of a global vision system for mobile mini-robots, using robot soccer as test platform. The proposed vision system consists of a camera, a frame grabber and a computer (PC) for image processing. The PC is responsible for the team motion control, based on the visual feedback, sending commands to the robots through a radio link. In order for the system to be able to unequivocally recognize each robot, each one has a label on its top, consisting of two colored circles. Image processing algorithms were developed for the eficient computation, in real time, of all objects position (robot and ball) and orientation (robot). A great problem found was to label the color, in real time, of each colored point of the image, in time-varying illumination conditions. To overcome this problem, an automatic camera calibration, based on clustering K-means algorithm, was implemented. This method guarantees that similar pixels will be clustered around a unique color class. The obtained experimental results shown that the position and orientation of each robot can be obtained with a precision of few millimeters. The updating of the position and orientation was attained in real time, analyzing 30 frames per second

Análise da dinâmica espaço-temporal de macrófitas submersas mapeadas com técnicas hidroacústicas no reservatório de Taquaruçu, rio Paranapanema

O objetivo deste trabalho foi avaliar o desenvolvimento da vegetação submersa, em termos da altura dos dosséis, considerando as dimensões espaço e tempo, usando técnicas de hidroacústica. Foram realizados dez levantamentos de campo no período de outubro de 2009 a dezembro de 2010, para aquisição de pontos georreferenciados de altura dos dosséis, frequência de ocorrência de vegetação, bem como de profundidade. Medidas limnológicas também foram feitas, a fim de verificar se suas variações poderiam explicar a distribuição espacial das macrófitas. Os dados de vegetação foram analisados por levantamento e por profundidade; além disso, compuseram um banco de dados implementado em um Sistema de Informação Geográfica. Foram então interpolados e das superfícies resultantes foram geradas cartas, que indicam a distribuição espacial do crescimento ou decaimento da vegetação. Modelos em três dimensões dos dosséis foram produzidos, para representar a ocupação volumétrica das macrófitas submersas. Os resultados mostraram que houve significativa redução da infestação de um ano para outro. Observou-se, ainda, que os maiores dosséis concentram-se em uma profundidade de 2 a 4 m. O mapeamento identificou tanto áreas de crescimento quanto de decaimento, distribuídas de modo heterogêneo. Não foi possível observar relação direta das medidas limnológicas com a dinâmica da vegetação, pois não apresentaram variação espaço-temporal significativa. Foi possível estimar o volume ocupado pelas macrófitas submersas, e a tendência observada é de que o aumento de volume é precedido por uma aparente homogeneização dos dosséis.

Acurácia e precisão: revendo os conceitos de forma acurada

Accuracy concepts that involve systematic and random effects and precision, that involves only random ones, are reviewed in this paper. An objective discussion is presented based on the definitions that appear in the literature, followed by examples that may be enough to clarify some concepts and allow the extension for other applications. The discussion presented aims at raising eventual inconsistencies in the interpretations so as to provide better possibilities of use for those involved with this topic, which is fundamentally important in the quality analysis of cartographic, geodetic and remote sensing or photogrammetric products.

Desenvolvimento de um protótipo de um atlas escolar interativo: projeto e produção

This paper aims at presenting an Interactive School Atlas prototype which was developed for cartography and environmental education. The methodology was based on the theoretical study about child mental development of Piaget theory, in order to elaborate strategies that allow the student a better comprehension about the spatial information understanding. It was defined as study case of sixth grade students, because they belong to the Formal Operation stage, in which the children reach the needed mental operations for understanding cartographic key concepts. This Atlas was developed in two stages: cartographic design and Atlas production. The Atlas implementation was developed seeking the use of Multimedia Cartography and animation resources that may attract students and teachers, instigating them to explore the tools and strategies to lead users to a correct interpretation of map contents. The Atlas was implemented by using the Macromedia Flash and Visual Basic softwares and the MapObjects library. Though the map has bot been evaluated yet, one should point out that it was designed according to the theoretical and methodological knowledge of the cognitive development and its relationship to cartographic conceptions, aiming at adapting the product to children cognitive skills.

O auto da morte e da vida : a escrita barroca de João Cabral de Melo Neto

This dissertation, entitled O Auto da Morte e da Vida: A escrita barroca de João Cabral de Melo Neto, has the aim of analising, interpreting, in a baroque perspective, Cabral s writing in the poem/play Morte e vida severina Auto de Natal Pernambucano, taking as basis the theories of Eugênio D´Ors, Severo Sarduy, Omar Calabrase, Lezama Lima, Afonso Ávila, Affonso Romano de Sant´Anna and others cited in the body of this work. During the analisys we feature confluences, relations, similarities, identification between the Baroque of the counter reformation and the modern Baroque or Neobaroque. We seek to comprehend the baroque which is new in the XX century and Cabral s poetry as an element of the contemporaneity, by updating the concept of the Baroque in the 1600s, when it is detected in its purest characteristic in human relation (the life of the Northwestern brazilian) through an intangible reality (the death). The Baroque as a cultural summary of a period of instability and transformation, with the power of dismantling an already established poetry. The fight between words and things, language and reality

O tratamento cartográfico da informação em saúde do trabalhador

Apesar do reconhecimento da importância dos conhecimentos geográficos e do uso das ferramentas de análise espacial nos estudos da saúde coletiva, esse é um campo ainda pouco explorado pelos pesquisadores brasileiros. em levantamento realizado nas principais revistas científicas que veiculam os resultados de pesquisa em saúde do trabalhador, verificou-se o grande predomínio do uso de tabelas e gráficos como meio de organizar e apresentar os resultados obtidos, e o número reduzido de mapas. Para isso foram examinados todos os artigos publicados em quatro periódicos (Revista de Saúde Pública, Cadernos de Saúde Pública, Revista Saúde e Sociedade e Revista Brasileira de Epidemiologia) no período de 1967 a 2009. Uma vez analisado o conjunto de artigos selecionados no estudo, aqueles que utilizaram representações cartográficas receberam atenção especial. Verificou-se que, embora ainda pouco utilizadas, as ferramentas do geoprocessamento e da geoestatística com suporte em SIG abrem um campo de novas possibilidades no uso da cartografia temática em saúde do trabalhador no Brasil. Contudo, recomenda-se para os editores das revistas científicas o detalhamento de normas técnicas para publicação de figuras cartográficas, assim como a elaboração de pareceres específicos que possam auxiliar os autores em vista das modificações necessárias para a melhoria da qualidade da comunicação visual de mapas e da correlação espacial por meio do tratamento cartográfico.

Estudo das propriedades críticas do processo de contato por par para diferentes atualizações

We study the critical behavior of the one-dimensional pair contact process (PCP), using the Monte Carlo method for several lattice sizes and three different updating: random, sequential and parallel. We also added a small modification to the model, called Monte Carlo com Ressucitamento" (MCR), which consists of resuscitating one particle when the order parameter goes to zero. This was done because it is difficult to accurately determine the critical point of the model, since the order parameter(particle pair density) rapidly goes to zero using the traditional approach. With the MCR, the order parameter becomes null in a softer way, allowing us to use finite-size scaling to determine the critical point and the critical exponents β, ν and z. Our results are consistent with the ones already found in literature for this model, showing that not only the process of resuscitating one particle does not change the critical behavior of the system, it also makes it easier to determine the critical point and critical exponents of the model. This extension to the Monte Carlo method has already been used in other contact process models, leading us to believe its usefulness to study several others non-equilibrium models

Ocidentalização, territórios e populações indígenas no sertão da Capitania do Rio Grande

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana

Arranjos urbanos e subjetivos contemporâneos na invenção de territórios turísticos

We seek consistency empirical and analytical rigor to the concept of touristification in the course of the contemporary arrangements of subjectivity and urbanity stations through a landscape of social (dis)encounters between residents and foreigners living in the capital of Rio Grande do Norte, Natal. In the last three decades the city has become a major destination country for national and international tourism, making tourism an important monitor of choreography in search of synchrony between cities and subjectivities, orchestrated by the cyclical crises and the relentless battle for systemic capitalistic expansion and survival. We proceed with an ethnographic and cartographic inspiration in Ponta Negra, where the waterfront redevelopment in 2000 conducted by the government, influenced the implementation of various establishments, services and practices related to the construction of Natal s major industry hub of tourism and entertainment. We proposed an arch-genealogy of touristification inspared on Michel Foucault analytical perspective, increased by authors in confluence or in different theoretical and methodological approaches, among which stand out Karl Marx, Gilles Deleuze and Felix Guattari, Michael Hardt and Antonio Negri. The reflections that initially turned to the advancement of the sphere of consumerism as the issue capable of articulating the developmental trajectory of the capitalist system and the practice of tourism, promoting some effects (un)desirable in the conflictual dynamics of the condition of the district of Ponta Negra, territory each again (re) produces the designs to meet the consumption by affluent portion of the population and foreign, encountering social exclusion and inclusion differentiated a growing trend. We go forward with an analysis of the "liberation of desire" phenomenal features of the process of producing subjective, providing a breakdown of the recent world s financial crisis initially, but proved social and political crisis also, through a plot derived from the operation of real estate speculation, which Natal is mainly caught through touristification, showing the outlines of a generalized crisis in establishing a new order buoyed by the emergence of a context "biopolitical" since it is a major route that uses the capital to survive and expand, while guiding the process of "strategic beautification" held in Ponta Negra, problematized by us. We conclude by assessing the appropriateness of proposing on further analysis to explore the establishment of a "new social ontology in terms of interference touristification ongoing and the constitution of a "new order" local/global, away from that characterize a system's capitalist overcoming, try to give emphasis in the current stage of the radicalization of a capitalistic utopia

Encontros entre dança, subjetivação e saúde mental

Taking from starting point the contact with the experience of a dancing body language group at Centro de Atenção Psicossocial (CAPS) II in Fortaleza-CE, aiming to investigate the relationship between what we denominate dancing-dispositive and the process of de-institutionalization of insanity. Based in the philosophy of difference and in the cartographic perspective, we used the concept of dispositive in order to make visible the lines that compose it and the way they tangle in the production of different ways of subjectivation through another form of expression using the body. We followed two fortnight groups of body language recording the conversations that took place in the beginning and in the end of the activities. We also recorded our informal talks with the workshopper, with the psychiatrist responsible for the course of formation of artists of CAPS and the choreographer who was part of the artistic formation of the workshopper aiming to elucidate the body, dance and art conceptions which guided such work. Finally, we interviewed some technicians and we participated of a meeting of the team aiming to understand how that activity was perceived. We observed that the use of certain conception of dance in the field of mental health is in consonance with the the Phychiatric Reform, since it provides another way of dealing with the body, different from that produced by the contention and by the discipline. Nevertheless, we understood that there is a risk that, in some moments, the group being more a place of normalization than one of experimenting other ways of relating with yourself and with the others. We also noted that the dancing-dispositive appears as an important analyzer of the connections established at CAPS, indicating a need of the service to be more opened to the production of new care and harboring strategies, breaking the mental health facility logic of incarceration of life which still persists in the quotidian of that institution
