A engenharia simultânea e o perfil da indústria de confecção da grande Natal/RN utilizando as ferramentas CAD/PDM e ERP

This work presents the research carried through in the industrial segment of confection of clothes of the Great Natal whose objective is to show the profile, enterprise and technological management as also the use of simultaneous engineering in the development of products. The research approaches two studies. The first one presents the current picture of the companies, synthesized through twelve variable. As, through fifteen variable it shows to the level of use of Simultaneous Engineering in the Development of Products and its amplitude in relation to the Integrated Management using tools CAD, PDM and ERP (Computer Aided Design, Product Management Date, Enterprise Resource Planning). The integration of these systems acts aiming the reduction of the cost and the development time of products. The reached results indicate that simultaneous engineering is a competitive advantage and becomes possible: to reduce the life cycle of the product, to rationalize the resources, to incorporate one high standard of the quality to the process and product as well as to personalize the product to take care of the global market. It is important to note that this work also is considered to contribute for the better understanding of the real companies situation of confection located at the Great Natal and its role in the economy of the State of the Rio Grande do Norte

Dificuldades na construção de gráficos de funções

This study describes about graduation s students difficulties of to draw functions graph. Specifically, we intend to observe their abilities evolution, as well as their difficulties during Calculus I subject in engineering course. For that, we show them publications about the elaboration of graphs and its difficulties in obstacle terms and some researches witch contain this subject and that it was done during postgraduate studies in mathematical education. It shows by research methodology aspects related to French didatic s mathematic and some theories of cognitive psychology considering the high value between theoretical-methodological relation that was evidenced in both theoretical conceptions about ways to understand and teach mathematic. This methodology is based on didactic engineering purpose, that consist in preliminaries analysis, conception and didactic sequence analysis prior, trials by application followed analysis up and conclusion. We had also used pedagogicals actions and analysis of results achieved, to classify types of errors made by the 2005 s students during second semester, from conceptions related to the episthemologic and didactics obstacles

Engenharia nos sertões nordestinos: o Gargalheiras, a Barragem Marechal Dutra e a comunidade de Acari, 1909-1958

In Brazil, between the late nineteenth and early decades of the twentieth, polytechnic engineers assumed an important role in discussing the establishment of a modern country. The problem of drought in northeastern Brazil gave the professionals performance, within an interventional process more mounts, the conception plans and measures for the purposeful integration of the territory afflicted. With the foundation of Inspetoria de Obras Contra as Secas (IOCS), in 1909, the actions to combat drought and would be institutionalized, them, studies performed out by technical and scientific committees would be systematically applied in the Brazilian Northeast. So, This work was central objective understand the historical process inplantation of a whole infrastructure of modern character by professional technical and their consequences within the Northeast Geographic space, in specific, in the municipality of Acari in the State of Rio Grande do Norte, in the first half of the twentieth century. The politics of the government, through technical education and scientific engineers polytechnics, would emphasize, during the twentieth century, the building of dams, and irrigation canals, wells, railways, highways, between other elements, that would soon transform the physical space-northeast, specifically, the territory acariense. These works began to contribute to the setting of man backcountry their land, promote the regular practice of agriculture even in periods of drought and, the integration, especially, economic of territory acariense the other producing regions of Rio Grande do Norte and the Northeast as well as promoting the modification of the landscape of the world backcountry. These actions functioned as elements of modernity and progress that transformed the space by favoring by favoring the formation of urban networks (urban) in this space

Sistema de apoio à interatividade em revisões sistemáticas em engenharia de software

A colaboração na pesquisa é uma das tarefas centrais da área acadêmica. Atualmente, muitos pesquisadores estão utilizando meios modernos de troca de arquivos digitais através de ferramentas assíncronas e também com o uso de ferramentas mais sofisticadas, do tipo síncronas. Juntamente com o fato da crescente quantidade de artigos sendo gerados, mais complexos, diversificados e aumentando de forma desorganizada, o que trás ao pesquisador uma tarefa difícil para organizá-los de forma a se extrair o melhor conteúdo destes, isto ocorre porque uma subárea da Engenharia de Software (ES) ainda é bastante mal aproveitada, a Engenharia de Software Experimental (ESE). Utilizando-se de um dos tipos de experimentos que a ESE oferece, as revisões sistemáticas entram como uma solução bastante robusta, na qual o pesquisador pode identificar o conhecimento existente em uma área e planejar devidamente sua pesquisa, evitando a repetição de erros em pesquisas já efetivadas por outros pesquisadores no passado. Contudo, estas duas abordagens, a colaboração virtual de pesquisadores e a utilização de revisões sistemáticas, contem problemas: na primeira, sistemas colaborativos são geralmente difíceis de configurar e usar; na segunda, apesar da robustez da metodologia de revisões sistemáticas, ainda se torna necessário uma rigorosa revisão na literatura para se conseguir um resultado satisfatório. Assim, com o foco de unir estas duas abordagens, este trabalho propõe uma maneira de produzir revisões sistemáticas de forma organizada e com a possibilidade de interação entre usuários, com o desenvolvimento de um sistema interativo, no qual as revisões sistemáticas possam ser geradas por usuários em colaboração com outros e também ser avaliadas seguindo a orientação de um profissional da área, tornando o seu conteúdo mais consistente e de melhor qualidade. O sistema não possui níveis de acesso, ou seja, qualquer pessoa pode se cadastrar e usufruir de seus recursos, seja na área acadêmica ou mesmo na área profissional
