RR3D: Uma solução para renderização remota de imagens médicas tridimensionais

The visualization of three-dimensional(3D)images is increasigly being sed in the area of medicine, helping physicians diagnose desease. the advances achived in scaners esed for acquisition of these 3d exames, such as computerized tumography(CT) and Magnetic Resonance imaging (MRI), enable the generation of images with higher resolutions, thus, generating files with much larger sizes. Currently, the images of computationally expensive one, and demanding the use of a righ and computer for such task. The direct remote acess of these images thruogh the internet is not efficient also, since all images have to be trasferred to the user´s equipment before the 3D visualization process ca start. with these problems in mind, this work proposes and analyses a solution for the remote redering of 3D medical images, called Remote Rendering (RR3D). In RR3D, the whole hedering process is pefomed a server or a cluster of servers, with high computational power, and only the resulting image is tranferred to the client, still allowing the client to peform operations such as rotations, zoom, etc. the solution was developed using web services written in java and an architecture that uses the scientific visualization packcage paraview, the framework paraviewWeb and the PACS server DCM4CHEE.The solution was tested with two scenarios where the rendering process was performed by a sever with graphics hadwere (GPU) and by a server without GPUs. In the scenarios without GPUs, the soluction was executed in parallel with several number of cores (processing units)dedicated to it. In order to compare our solution to order medical visualization application, a third scenario was esed in the rendering process, was done locally. In all tree scenarios, the solution was tested for different network speeds. The solution solved satisfactorily the problem with the delay in the transfer of the DICOM files, while alowing the use of low and computers as client for visualizing the exams even, tablets and smart phones

EUPAT for WoW: Uma ferramenta de assistência à programação por usuário final

Neste trabalho, apresentamos uma ferramenta cujo intuito é auxiliar não-programadores, jogadores de videogame, na criação de extensões na forma de Add-ons para World of Warcraft, o jogo online. Nele, o usuário pode criar extensões customizando completamente sua interface, de forma a reinventar a sua experiência de jogo e melhorar sua jogabilidade. A criação de extensões para aplicativos e jogos surgiu da crescente necessidade de fornecer aos usuários mecanismos eficientes de Programação por Usuário Final, permitindo que os mesmos preenchessem suas necessidades singulares através da criação, customização e especificação de extensões em software. Em World of Warcraft mais especificamente, os Add-ons exploram um tipo de extensão na qual os jogadores passam a programar sua própria interface de usuário ou a fazer uso de interfaces criadas por outros usuários. No entanto, realizar a programação dessas extensões - os Add-ons - não é uma tarefa fácil. Dentro deste contexto, desenvolvemos a ferramenta EUPAT for WoW (do inglês, End-User Programming Assistance Tool for World of Warcraft) que oferece assistência à criação de Add-ons. Além disso, investigamos como usuários jogadores com e sem conhecimento de programação são beneficiados. Os resultados desta pesquisa permitiram refletir sobre as estratégias de assistência de programação por usuário final no contexto de jogos

O turismo de base local como um possível indutor de desenvolvimento rural: uma análise da realidade e das potencialidades no distrito de dondo-moçambique

The current debate on rural development focuses on the territorial approach, recognizing the multifunctional character of rural areas. Emphasize the use of endogenous forces, the need of implement policies which valorize local specificities, the participation of social actors in revitalization of rural areas. In this context tourism enters as a means to induce a new dynamic to rural areas, since the activity is regarded as a channel for the upgrading of the natural and cultural resources and the rural way of life. This study focuses on local-based tourism as a promoter of rural development, giving an analysis of the social reality and potential for this tourism in the district of Dondo. In it, is proposed to analyze the potential for development of local-based tourism in the district of Dondo, assessing the extent to which local reality enables the inclusion of the community in the management of local tourism resources. For this, was showed the inclusion of local-based tourism in the current context of rural development, was identified and organized systematically the factors that influence the implementation of local-based tourism in the study area and was verified as far as possible the study area corresponds to the constraints identified, showing how local-based tourism can best been encouraged. Was adopted a qualitative methodological approach to both the procedures and data processing, but also by critical approach, using bibliographical research, semi-structured interviews that fell on the group of public administrators who work in tourism and community leaders. The critical analysis was based on the principles of sustainability o Sachs particular ecological, social, cultural, economic, space, beyond the analysis of political and institutional aspects. The survey results show that the district of Dondo has a potential for implementing a model of tourism development on a local basis, since it is rich in natural and cultural research, benefits from good network accessibility in the context of the market in the region, the population live according to their habits and customs and value their identity. There is also a good cooperation between community members, although not in tourism, a fact which is observed through the lever of community participation in associations, cooperatives, working in areas such as agriculture, fishing, environment, civic education etc. It also has public funding sources to augment or stimulate local investment. Despite obstacles such as inexistence of policies and local plans for tourism development, lack of awareness of tourism, lack of basic infrastructure, as well as equipment and facilities to support tourism, the results shows that these problems can be solved through a public commitment from both government, and community through a joint planning and participation

A moralidade e a vida pregressa do candidato como condição autônoma de elegibilidade

The objective of this work was about fixing the free will paradigm as negative evaluation of political rights which presents a new classification dde such rights, producing species: a) conditions of eligibility autonomous (free will), b) eligibility requirements heteronomous (will third party) and c) ineligibility (court decisions / administrative). This morality and life history as a condition of eligibility unattended, making a hermeneutic analysis of art. 14, § 9 of the Constitution, considering the justification of the views of the voting Minister Carlos Ayres Brito Appeal in Ordinary No 1069/2006 of the Supreme Electoral Tribunal (where Eurico Miranda). Are fixed concepts of morality and life history from the perspective of the moral act freely and consciously. Has resulted in the identification of the moral virtues of honesty and integrity, which are voluntary acts as a reference to morality and integrity respectively. Justifies the morality and life history as a condition of eligibility unattended. who depend exclusively on the willingness of the candidate. It is noteworthy that the conditions for eligibility as a factual finding does not violate the law and does not allow punitive sanctions or setting a deadline in case of refusal to register the application. Attributed to political parties to take responsibility in their statutes moral criteria for the nomination convention in pre candidates, giving an ethical dimension. Analyzes the law under the Clean Record of morality and life history of the candidate and the possible impact on the electoral context

Corpos brincantes: a cultura corporal do pastoril potiguar

Pastorais, Bailes Pastoris, Festa da Lapinha, Terno de Reis, Pastor, Pastoril Religioso ou Profano... Pastoris do Norte e Nordeste brasileiro. M ário de Andrade designou-o de Pastoril, folguedo de origem ibérica, tendo sua raiz primeira nos villancico. Considerando que o Pastoril é um folguedo popular, porque nele seus participantes engajam sua vida pessoal, sua cultura e suas influências, revelando modos de ser e compreender, que são interiorizados pelos brincantes a partir da vivência de seu contexto social múltiplo e de diferentes sentidos, é que situamos esse folguedo no mundo vivido fenomenológico. A investigação é de natureza fenomenológica, elucidando os elementos citados como cenário do vivido e do sensível. O presente trabalho tem como objetivo refletir sobre a compreensão de corpo encontrado nos pastoris norteriograndenses

A experiência do corpo na dança butô: indicadores para pensar a educação

Neste artigo pretende-se refletir, apoiado em alguns ensaios de Merleau-Ponty e com base na fenomenologia, acerca do corpo e das narrativas e saberes que nele se anunciam na dança butô — modalidade que combina dança e teatro, criada no Japão na década de 1950. De modo geral, o corpo foi compreendido como elemento acessório no processo educativo, e essa compreensão ainda é predominante no contexto atual. Nossa reflexão tenta apontar outros caminhos de entendimento do corpo na educação, a partir de uma atitude que busca superar o instrumentalismo e ampliar as referências educativas, ao considerar a fenomenologia do corpo, e sua relação com o conhecimento sensível, como aquela capaz de amplificar a textura corpórea dos processos de conhecimento. Considerando a experiência do corpo na dança butô, apresentamos indicadores para pensar a educação, relacionados à experiência estética. Dentre eles destacamos: a plasticidade do corpo, a sua produção incessante de ressignificações, a sua abertura à inovação, a sua condição mutante, a sua ruptura com a mecanização gestual, a sua não dissociação entre homem e mundo, pensamento e sentimento. Todos esses aspectos que reúnem o saber recursivo, integrativo e criativo do corpo, são indicadores para pensarmos na educação, por tratar-se de uma nova possibilidade de leitura do real, a partir da linguagem do gesto, em que dialogam saberes e práticas inscritos na experiência corporal

A produção do espaço rural no município de Ceará-Mirim

This research intended to study the process of production of the rural space in the municipal district of Little Ceará-Mirim, looking for to identify the transformations in him happened, above all in the last thirty years. Since the beginning of your historical formation, the area in study had as element modelador and transformer of the physiognomy of your territory the culture canavieira that printed in your economy and in your society marks of a powerful nobility. The sugar-cane is covered of a cyclical character facing acme phases and decadence, as the one that it happens at the present time. Simultaneously, the sphere rural cearimirinense is going by changes by the implantation of modern companies gone back to the papaya production destined to the internal market and more precisely to the external market. Of this context they also consist the supplying farms of this same product. In the group of the establishments in the rural landscape here analyzed, they still interfere the mixed farms, the ones that practice agriculture, the ones that were devoted to the livestock, as well as the farms and the ranches. Another innovation is the caprinocultura developed in modern molds, using the system voisin of pasture rodízio being constituted in a pioneering experience in Brazil. Of that reality they announce other elements, to example of the establishments, being configured as new forms of use of the soil. In the perspective of turning them productive, the challenge resides of overcoming the difficulties in them existent. The reality of the space in screen is replete of lacks in all the instances. It is inferred that the municipal district possesses an enormous potential, however the performance of the administrative components is seen as deficient. He becomes urgent that the municipal public power promotes changes, mainly in what it respects to the social area, with a better attendance to the rural communities, for them to act positively in the process of the development of this municipal district

Acari-RN: da construção do território aos limites da pobreza

Acari-RN is one of the earliest municipalities in the region of Seridó Potiguar in rio Grande do Norte. In this municipality, two feelings coexist: power and loss. The former, justified by the process of occupation, which gave birth to its micro-region and the latter, marked by economic impoverishment, starting from the decade of 1970, with the decline of its main wealth: the cotton economy. From the association of these feelings, the motivation for the construction of this piece of work emerged. In it, poverty and inequality are discussed, in a dialect relation with the territory, through a theoretical-methodological reflection and from the analysis of the data collected in a field research. In order to valorize and enrich the theme and the study of the territory of Acari, it was necessary to compare it with the other municipalities that it generated: Currais Novos, Jardim do Seridó and Parelhas. Therefore, the use of the elements of a quantitative and qualitative research, applied in the study section, aimed at finding the poverty indicators, which make it difficult the development in Acari.

A construção e estruturação do território comercial no bairro Alecrim Natal/RN

The study done has as objective the comprehension of the constructed territorial spaces through the commercial perspective, because it is a social practice which enables the dynamic of the space and the appearing of territories. Related to the territory, we emphasized the interest for the idea of used territory treated by Milton Santos, because we agreed with him believing that is the use of the territory which warrants its legitimacy. Then, the spatial dimension chose concentrates itself into the district of Alecrim, localized at the east zone of Natal/RN, where it is recognized by its strong commercial dynamic which was built during years, facing some events which happened in the context of the city. However, this dynamic counts with a hard dichotomy which involves as the considered by the State formal activities, as the informal one. About the commerce of the district, it has characteristics into its activities whose make him to be considered popular, as by the existing products, as by the strong presence of informal workers that constitutes the district s landscape. The informal workers practice expresses one of the multiples constructed alternative territorialities. We believe that this fact has direct relation with the growing process of the exclusion from the formal jobs market. Still talking about the spatial dimension, this real example of the Alecrim district shows how the techniques changes, together with the capitalism process, may influence one entire spatial dynamic across years, involving many agents, since the transient people from somewhere, until the State. Shall the Geography understand the multiple forms from the space, face to the relations that occur into it and also how new territories have been built

O uso de modelos ocultos de Markov no estudo do fluxo de rios intermitentes

In this work, we present our understanding about the article of Aksoy [1], which uses Markov chains to model the flow of intermittent rivers. Then, we executed an application of his model in order to generate data for intermittent streamflows, based on a data set of Brazilian streams. After that, we build a hidden Markov model as a proposed new approach to the problem of simulation of such flows. We used the Gamma distribution to simulate the increases and decreases in river flows, along with a two-state Markov chain. The motivation for us to use a hidden Markov model comes from the possibility of obtaining the same information that the Aksoy’s model provides, but using a single tool capable of treating the problem as a whole, and not through multiple independent processes

Proposta de válvula bypass para controle de velocidade de PIGs instrumentados: protótipo e simulação em bancada

In the Oil industry, oil and gas pipelines are commonly utilized to perform the transportation of production fluids to longer distances. The maintenance of the pipelines passes through the analysis of several tools, in which the most currently used are the pipelines inspection cells, popularly knowing as PIG. Among the variants existing in the market, the instrumented PIG has a significant relevance; acknowledging that through the numerous sensors existing in the equipment, it can detect faults or potential failure along the inspected line. Despite its versatility, the instrumented PIG suffers from speed variations, impairing the reading of sensors embedded in it. Considering that PIG moves depending on the speed of the production fluid, a way to control his speed is to control the flow of the fluid through the pressure control, reducing the flow rate of the produced flow, resulting in reduction of overall production the fluid in the ducts own or with the use of a restrictive element (valve) installed on it. The characteristic of the flow rate/pressure drop from restrictive elements of the orifice plate is deducted usually from the ideal energy equation (Bernoulli’s equation) and later, the losses are corrected normally through experimental tests. Thus, with the objective of controlling the fluids flow passing through the PIG, a valve shutter actuated by solenoid has been developed. This configuration allows an ease control and stabilization of the flow adjustment, with a consequent response in the pressure drops between upstream and downstream of the restriction. It was assembled a test bench for better definition of flow coefficients; composed by a duct with intern diameter of four inches, one set of shutters arranged in a plate and pressure gauges for checking the pressure drop in the test. The line was pressurized and based on the pressure drop it was possible to draw a curve able to characterize the flow coefficient of the control valve prototype and simulate in mockup the functioning, resulting in PIG speed reduction of approximately 68%.

O cinema como educação do olhar

The knowledge is only possible due to we exist bodily. However, during the educational experience, the epistemic potency of the body is neglected, declining the registers of the intelligibility. The current thesis approaches that problem obliquely: from a body and image philosophy which has revealed other ways of doing those registers in the modernity – understood not as period itself, but as a qualification for the negotiations between the real and the intelligible. The referred ways are explored through Merleau- Ponty’s and Michel Foucault’s works, which offer a spectrum about that new negotiation of the real. In order to approach the studied problem, the visibility and the human body motricity in the cinema are taken as analysis object. The mentioned objects have been analyzed through a corpus of movies of which plots are centered at the formal education and they require from the characters and the spectators engagement into a visual performance. Aiming to approach the object, it is questioned how the Education phenomenon is represented by the cinema; how the body is exposed and how spectators can see it. Analyzing the corpus and articulating Merleau- Ponty’s and Michel Foucault’s theories, it has been possible to state the following thesis: the cinema as an education of the gaze. The general objective of this study is to reveal the educational potency of the filmic experience, which provides a new path of intelligibility for Education. In that sense, the body as a visual operator widens the capacity of understanding the real. The current work is divided in three chapters. The first one brings the methodological approach: it is pointed how the theoretical articulation is properly arranged; it explains the method of using the images as indirect language as part of the reality description; the filmic corpus is presented, as well the criteria for the films choices and for the construction of instrument adopted during the object analysis are described. In the second chapter, it is problematized the incapacity of the western society of formulating the real discursively by debating Merleau-Ponty’s and Foucault’s theoretical contributions about the visual performance displayed on the images while the films are watched and analyzed. In the third chapter, the implications of the education of the gaze provided by the cinema are developed, mainly concerning about the place attributed to the visibility during the formulation of the real. Finally, paths are designed for the construction of another approach for the visibility in Education. Assuming the gaze as an experience of knowledge, this study aims to present other ways of being, seeing, thinking and feeling the world. Therefore, it is a proposal to reset the epistemic and subjectification patterns at the educational context.

Escola: lugar político da diversidade sexual e de gênero

This work aims to understand how the public school system has become a failing institution with regards to sexual and gender diversity. I start from the principle that the school system performs a social sorting operation, leaving out of its halls almost all people who don‘t fit into the established heteronormative social order. First, I explore the experiences of primary school (Educação do Ensino Fundamental) professionals from the public network (Rede Pública Municipal) of the city of Natal-RN. I consider their narratives a result of daily practices which denounce the rules that govern and produce them in a broader context. Then I aim to establish a dialogue with the students who are victims of name-calling, teasing and abuse for not aligning with the ―normal‖ gender standards. At this stage of the research, I conducted fieldwork at the State Secondary School of Rio Grande do Norte (Escola Estadual de Ensino Médio). This investigation is guided by the following questions: What challenges need to be addressed in order to recognize the students who have been excluded from the school environment on account of sexual and/or gender differences; additionally, how can their classroom attendance and positive learning experience be ensured? To what degree is the school community concerned with building education practices which value and acknowledge sexual and gender diversity? The research goals were: to analyze how the school and its professionals deal with sexual and gender diversity, investigating which pedagogical practices silence, freeze and obstruct the diversity of student identities; examine how the school and its subjects work toward building new pathways for learning, for coexistence, and for facing the challenges of ―new‖ social demands such as homoaffection; observe the spaces that are cracked open by the presence and the voices of students who demand recognition of their existence.

Ensinando e aprendendo a ler na escola infantil: reflexões sobre o saber-fazer de uma professora

Este trabalho objetivou uma reflexão sobre a ação mediadora no processo de ensino-aprendizagem da leitura, por mim vivenciada no Núcleo de Educação Infantil (NEI/UFRN) junto a crianças de 6/7 anos, tendo como proposta explicitar os elementos orientadores necessários a esse processo, que se traduzam como referência a outras práticas educativas. Sua realização pressupôs as seguintes questões: que conteúdos estão envolvidos no ensinoaprendizado da leitura? Como os alunos aprendem a ler? Que tarefas são instrumentais no ensino e aprendizado da leitura? Nele foi adotada a concepção de leitura enquanto atribuição de significados a um texto escrito através do processo interativo entre leitor e texto, guiado pelos objetivos/finalidades deste leitor. Adotou os princípios metodológicos da abordagem qualitativa, entre cujas características salienta-se a primazia do interesse pelo processo do que simplesmente pelos resultados ou produto. Seus resultados evidenciaram que a leitura, enquanto prática cultural, pode ser aprendida na escola infantil, espaço de apropriação de saberes mediados pela cultura. Constatou-se que, a exemplo das demais aprendizagens, o aprendizado da leitura implica numa atividade mediada em que o professor, administrando e organizando o meio social educativo, cria espaços de diálogo para as muitas vozes presentes nesse meio. Gera, desse modo, um contexto polifônico, dialógico e de alteridade pela ação de planejar/avaliar/replanejar a sua atuação e a de seus alunos. A relevância deste estudo concerne à intenção de socializar uma vivência, cuja tônica é a reflexão sobre a leitura enquanto prática cultural e as estratégias de ensinar e aprender a ser leitor.
