Redes em Malha sem Fio ( do inglês Wireless Mesh Networks - WMNs) são previstas serem uma das mais importantes tecnologias sem fio no que se refere ao fornecimento do acesso de última milha em redes multimídia futuras. Elas vão permitir que milhares de usuários fixos e móveis acessem, produzam e compartilhem conteúdo multimídia de forma onipresente. Neste contexto, vídeo 3D está previsto atrair mais e mais o mercado multimídia com a perspectiva de reforçar as aplicações (vídeos de vigilância, controle demissões críticas, entretenimento, etc). No entanto, o desafio de lidar com a largura de banda optante, escassez de recursos e taxas de erros variantes com o tempo destas redes, ilustra a necessidade da transmissão de vídeos 3D mais resistentes a erros. Dessa forma, alternativas como abordagens de Correção Antecipada de Erros (FEC) se tornam necessárias para fornecer a distribuição de aplicações de vídeo para usuários sem fio com garantia de melhor qualidade de serviço (QoS) e Qualidade de Experiência (QoE). Esta dissertação apresenta um mecanismo baseado em FEC com Proteção Desigual de Erros (UEP) para melhorar a transmissão de vídeo 3D em WMNs, aumentando a satisfação do usuário e permitindo uma melhoria do uso dos recursos sem fio. Os benefícios e impactos do mecanismo proposto serão demonstrados usando simulação e a avaliação será realizada através de métricas de QoE objetivas e subjetivas.

Este artigo tem por objetivo analisar a dinâmica de redivisão territorial político – administrativa municipal da Região Norte do Brasil no período de 1988 a 2010. A revisão da malha político – administrativa municipal no Brasil, se associa diretamente à múltiplos fatores, entre os quais destacamos: as mudanças na ordem política e institucional brasileira, principalmente, no que diz respeito a alternância de períodos de centralização e descentralização político administrativa; a redistribuição da população no território e ao processo de urbanização. Esses fatores foram significativos na Região Norte do Brasil.

The invention of a modified nylon mesh for structural reinforcement of dental prostheses is described, said modified nylon mesh comprising polyamide fibres and 0.3%-0.5% v/v silicon dioxide (SiO2), which enables chemical binding between the acrylic resin and the polyamide mesh in order to increase the strength of the resin/polyamide complex in said dental prosthesis.

The work consists of the historical city of Guaratinguetá, as well as data on their quality of life, economic development and population, transportation in Brazil and the transportation system of the city serving as a basis to support the development of the urban network. The urban fabric of the city was raised with plants of the city in different years, documents obtained by the Museum and Hall of Frei Galvão Guaratinguetá well to check the form of land use and growth drivers of the city over time. We studied also the main access roads to the city by focusing on an approach that has been the subject of a proposed urban intervention. A direct interview was performed and recorded with one of those responsible for planning the urban fabric of the city in order to gather information on the historical development, the future possibilities of interventions in the urban as well as problems encountered and other curiosities. Through the study it was observed that the urban grid Guaratinguetá developing a planned since 1970 and that the highlights of most cities in the Paraíba Valley. The work is grounded in concepts of sustainable city and also in quantitative and qualitative data from sectors responsible

The city of Jacareí above average presents a economic growth of the State of São Paulo, fact that comes if reflecting in the quality of life of the citizens, due to lack of infrastructure to hold the growth rhythm. Today the commercial center of the city, presents diverse urban conflicts with its narrow streets and sidewalk making it difficult to the locomotion and the access the areas and building of public interest gifts in this region. Aiming at the arrival of four multinationals that already make gratings investments in the city and the promise of growth and dinamização of the still bigger economy for the next years, this work studies the urban mesh of the city for a possible implantation of a Technological Park that serves of inductive element of the development of the region north of the city of Jacareí. Place, in which, they are being constructed the multinationals and where, according to Managing Plan of the city, the city hall intends to urbanizar in the next years, with the objective to minimize the areas of urban conflict in the commercial center and of form to absorb the growth of the city. From the study of old experiences, of works carried through on the subject, interviews with city planners of the e region after visits to the place, we will go to argue the possibility of implantation of the Technological Park in Jacareí and optimum place for its installation

The perceived exertion has been used for the intensity control and exercise prescription. Among the various scales that estimate the perceived exertion, the Borg’s RPE scale is one of the best known. However, for populations with low levels of schooling or with visual difficulties such as the elderly, the application of these scales becomes more difficult. In previous studies, a color scale of perceived exertion was developed to aim for assistance in application of the scale and interpretation of perceived exertion. This scale showed high correlation with the Borg’s scale and proved to be valid to estimate the perceived exertion. Thereby, the aim of this study was to assess the validity of the color scale of perceived exertion to measure the perceived exertion in adult women of different ages. Participated in the study 12 young adult women with age of 21,7 ± 1,5 years old, and 10 elderly women with age of 60,3 ± 3,5 years old. The participants were submitted to an incremental exercise of treadmill walking with stages of 2 minutes duration. The inicial load was 5,5 km/h and inclination of 6% for young women and 2% for elderly women, both with 2% increments at each stage completed, without changing the speed. Heart rate and oxygen comsuption responses were determined at the 30 finals seconds of each stage. At the 60 finals seconds of each stage participants indicated the perceived exertion for the overall body, for the legs and for the chest, primarily in the color scale and following in the tradicional Borg’s scale. The analysis of variance for repeated measures was used to assess the effect of different loads on the perceived exertion and physiological responses. The correlations betwen physiological variables, color scale and Borg’s scale were analyzed in group and individually. In all analysis the significance...(Complete abstract click electronic access below)
