Yes, nós temos arquitetura moderna! Reconstituição e análise da arquitetura residencial moderna em Natal das décadas de 50 e 60

Brazilian architecture was recognized because of the consecration of the icons of the Carioca and Paulista schools which are represented nationally and internationally by names like Niemeyer, Lucio Costa and Vilanova Artigas, among others. Because of this, classic studies dedicated to the Brazilian case look to present the Southeastern region with the title of father of modern Brazil, at the cost of subjugating various other modern movements and peripheral sayings, whether their values are known or forgotten. On the other hand, there has been an effort, in the sense of registering and analyzing these regional productions of modern Brazilian architecture, an assignment that DOCOMOMO Brasil participates firmly through initiatives like the creation of a Library to aid in the documentation and registration of modernity in Brazil. Inside this context of insertions of the National-Modern scheme, this work has as its objective to present modern potiguar (northern Brazil) architecture through its contemporary residential examples, investigating specifically its constructive, formal aspects, that together that together demonstrate one more architectural emphasis of modern Brazilian architecture: the potiguar. This way, by contributing to the work of the register and the documentation of the Modern Movement and attributing to the modern architecture of Natal it s real worth, we can say: Yes, we have modern architecture

Otimizações da transmissão de imagens em redes de sensores visuais sem fio explorando a relevância de monitoramento dos nós fontes e codificação DWT

The development of wireless sensor networks for control and monitoring functions has created a vibrant investigation scenario, covering since communication aspects to issues related with energy efficiency. When source sensors are endowed with cameras for visual monitoring, a new scope of challenges is raised, as transmission and monitoring requirements are considerably changed. Particularly, visual sensors collect data following a directional sensing model, altering the meaning of concepts as vicinity and redundancy but allowing the differentiation of source nodes by their sensing relevancies for the application. In such context, we propose the combined use of two differentiation strategies as a novel QoS parameter, exploring the sensing relevancies of source nodes and DWT image coding. This innovative approach supports a new scope of optimizations to improve the performance of visual sensor networks at the cost of a small reduction on the overall monitoring quality of the application. Besides definition of a new concept of relevance and the proposition of mechanisms to support its practical exploitation, we propose five different optimizations in the way images are transmitted in wireless visual sensor networks, aiming at energy saving, transmission with low delay and error recovery. Putting all these together, the proposed innovative differentiation strategies and the related optimizations open a relevant research trend, where the application monitoring requirements are used to guide a more efficient operation of sensor networks

A mídia dos outros somos nós: a experiência audiovisual do Ponto de Cultura Cinema para Todos

This research aims to identify the process of appropriation of audio visual (in digital video) for collective symbolic production (participatory video practice that expresses popular culture) in a socio-cultural context where the minorities are. Therefore, we based this study on the students‟ experience of the film and video workshops held by Cinema para Todos (Culture Point Cine for All), in Natal, RN. Culture Point is the basis of the project Programa Nacional de Cultura, Educação e Cidadania Cultura Viva (National Program of Culture, Education and Citizenship - Living Culture) of the Brazilian Ministry of Culture. In 2010, the Cine for All developed three film and video workshops in the state of Rio Grande do Norte (Northeastern of Brazil), in the municipalities of Açu, Lajes and São Gonçalo do Amarante, within a public policy project of socio-cultural inclusion. These three workshops are the focus of this empirical investigation. To support the analysis of this research we consider that the spaces of workshops are sites of the social practices origin, assuming they show the development of the changes of actions that generate new practices. In this socio-cultural context the students as interlocutors process the communicative culture mediation, where come from the logics of action (using digital video) to become a mediatic practice (video auto ethnographic). With the overall goal set and the field of investigative action delimited we considered the methodology of case study suitable for the observation of the object, because it is a phenomenon of modernity, occurring in a context of real life and with little or no control over events. Participant observation and interviews was also applied to this case study. The analytical theoretical support comes from the notion of mediation by Jesús Martín-Barbero and the concept of habitus by Pierre Bourdieu. The research found that a new way of communicating has been developing by this social group, and this reflects the technological change experienced by them. The auto ethnographic videos, short movies, reveal an allegorical trial of the mainstream media, because while they use the mainstream format, they rework the aesthetic, but without revising the history, in fact they proposing to retell the history of themselves full of colorful details and with richness of their forgotten popular culture.

Em nome da cidade vencida: a São Luís republicana em José do Nascimento Moraes (1889 1920)

Cette dissertation a pour but d´analyser la ville de São Luís do Maranhão pendant la Première Republique, d´après le roman Vencidos e Degenerados, de José do Nascimento Moraes, publié en 1915. À partir des rapports entre l´Histoire et la Littérature, nous nous intéressons à la façon dont l´auteur écrit l´histoire d´une ville qui, après la fin de l´esclavage et l´installation de la Republique, conserve des anciens préjugés de race et reste plongée dans l´immobilité economique. Le roman fait partie d´un ensemble d´oeuvres scientifiques et littéraires d´une géneration connue sous le nom de Novos Atenienses (nouveaux athéniens), laquelle discutait la crise économique et culturelle vécue par le Maranhão au tournant des XIXe et XXe siècles. Le discours formulé par les nouveaux-athéniens comprennait des eléments nostalgiques associés au culte des lettres envisageant la conquête de la réconaissance littéraire et le désir d´adapter la ville de São Luis aux modèles de progrès et modernisation de la période républicaine. Dans ce contexte, Moraes introduit les thèmes liés à la discrimination raciale qui demerait après la fin de l´esclavage, qu´il considérait un obstacle au progrès de la capitale de Maranhão, et aussi la cause des pérsecutions littéraires dont il était victime. On a analisé le roman en cherchant compreendre les rapports entre les individus et les rapports qui´ils entretienent avec les spaces de la ville, à partir de questions d´ordre littéraire, raciale et urbaine. En guise de conclusion, la narration de l´oeuvre est dévellopée de façon que la ville, peuplée de gens de couleurs, sert à legitimée l´oeuvre littéraire de Moraes, dont le nom a été oublié dans les principaux cercles littéraires de la capitale pendant la période examinée

Extensões ao Projeto LVWNet: mobilidade, interação com equipamentos reais, comunicação direta, e registro dinâmico de nós

Due to the constantly increasing use of wireless networks in domestic, business and industrial environments, new challenges have emerged. The prototyping of new protocols in these environments is typically restricted to simulation environments, where there is the need of double implementation, one in the simulation environment where an initial proof of concept is performed and the other one in a real environment. Also, if real environments are used, it is not trivial to create a testbed for high density wireless networks given the need to use various real equipment as well as attenuators and power reducers to try to reduce the physical space required to create these laboratories. In this context, LVWNet (Linux Virtual Wireless Network) project was originally designed to create completely virtual testbeds for IEEE 802.11 networks on the Linux operating system. This paper aims to extend the current project LVWNet, adding to it the features like the ability to interact with real wireless hardware, provides a initial mobility ability using the positioning of the nodes in a space coordinates environment based on meters, with loss calculations due to attenuation in free space, enables some scalability increase by creating an own protocol that allows the communication between nodes without an intermediate host and dynamic registration of nodes, allowing new nodes to be inserted into in already in operation network
