This work deals with the sequencing of Multi-Mixed-Model Assembly Lines in a lean manufacturing environment, where an operational structure where several kanbans support several mixed-model assembly lines, so that all assembly lines can receive parts or sub-assemblies from all suppliers. To optimize this system, the sequencing seeks to minimize the distance between the real consumption and the constant ideal consumption of parts or subassemblies, thereby reducing the scaling of kanbans and intermediate stocks. To solve the sequencing problems, the method Clustering Search was applied along with the metaheuristics Variable Neighborhood Search, Simulation Annealing and Iterative Local Search. Instances from the literature and generated instances were tested, thus allowing comparing the methods to each other and with other methods presented in the literature. The performance of the Clustering Search with Iterated Local Search stands out by the quality and robustness of their solutions, and mainly for its efficiency, whereas it converges to better results at a lower computational cost

In modern days is not practicable to link productivity and profitability without discuss the manufactured products quality. It is of great importance, mainly if the company is looking for a Global Class title, both the product and the process in what it is been fabricated, to attend all the high level quality requirements. This work aims to define the necessary steps for implementing a new project, including the initial viability studies, and then the staff approval, passing through the development of tools and documents necessary to its fabrication, purchasing goods and services to build the installation, and the final stage of implementation, focused on the manufacturing process quality. It will be highlighted a quality tool that helps do decrease the process risks and thereafter increase its reliability after the implementation

Over the years is a significant number of researchers consider constructivism as a methodology above the rest and that can be applied to any educational context, and is therefore the ideal methodology in the present moment. However, as opposed to this idea, there is a growing body of research that consider the methodological pluralism how best to teach in class, precisely because it is not just one, but several methodological practices which vary according to the educational needs of students. This exhibit features four lessons presented to students of 6th and 8th grade of elementary school II, two lessons using experimental activities, a lesson using Demo activity and a lesson using texts textbooks. In all four lessons there was a collection of data on students' understanding about the physical concepts covered by each of the above four lessons either through questionnaires, video recording, and more. Based on Vygotsky's theory of social interaction and constructs Wertsch (1984), this article raises important discussions about the advantages and disadvantages of these three methodologies within the pluralistic proposal

In this work it was made analysis of a simple pressure vessel, using the analytical development studied in Mechanics of Materials disciplines, and then using the standard required by ASME. Following the simulation was realized using Autodesk Mechanical Simulation software to calculate the principal stresses in a pressure vessel. The simulation was done in a single vessel without nozzles, compared with the analytic calculation. After that, the simulation of another fictitious pressure vessel was done by adding three nozzles to verify the influence of the nozzles in the principal stresses and compared with the analytical results. After the simulation, it was found that the principal are bigger in the pressure vessel with nozzles, but they decrease at a small distance from the nozzle becoming equal to the stresses in the vessel without nozzles. The analytical results calculated according to the ASME agree with simulated results

In this era of globalization, with fierce competition in the labor market, using the reduction cost strategy and resources optimization, has become a competitive advantage. In this graduation study, it will be exposed in form of case study the DMAIC project (Define Measure Analyze Improve Control) execution, using of Six Sigma's tools, statistical and quality knowledge, with intent of analyze, improve and control the processes of a selected problem, always demonstrating good practice of methodologies. In an auto parts multinational branch, It was identified a high scrap rate in one of his production lines. This work will study this problem to improve their processes and ensure that these improvements are perpetual. As a result, reached the stipulated goals, increasing Corporation's Intellectual, thereby providing a competitive advantage

Pode-se observar nos últimos anos o crescente uso do termo intercultural(idade) nos discursos educacionais, sobretudo os que tratam da língua estrangeira. Esse termo vem ganhando espaço nos Parâmetros Curriculares Nacionais (PCNs), nas Orientações Curriculares, no Programa Nacional do Livro Didático (PNLD), nos prefácios dos livros didáticos e nas inúmeras investigações acadêmicas publicadas sobre educação. Longe de ser um ensino focado exclusivamente nas estruturas formais, metalinguísticas, nas habilidades comunicativas, na preparação para o mercado de trabalho ou vestibulares, o ensino intercultural tem como objetivo o desenvolvimento de outros aspectos no sujeito aprendiz, como citado nas Orientações Curriculares do ensino médio de 2006: “ter consciência, entender e aceitar esses novos valores e crenças presentes em diferentes grupos sociais”. Se combater esses fatores por si só não é uma tarefa fácil para o professor de línguas, este ainda conta não raras vezes com a falta de formação adequada sobre o assunto, com a influência homogeneizante da mídia, e muitas vezes somente pode recorrer aos materiais didáticos, previamente selecionados pela instituição escolar. Nesse sentido, o objetivo de nosso trabalho é descrever e analisar de que maneira os livros de espanhol do ensino médio escolhidos pelo PNLD-2012, a saber, Síntesis, El arte de leer español e Enlaces, tratam a questão da interculturalidade. A fim de limitarmos o nosso corpus, optamos por analisá-los por um tema comum – o tema alimentação. Essa escolha justifica-se, pois os três livros didáticos escolhidos apresentam uma lição exclusiva para essa temática e acreditamos ser um valioso objeto de reflexões culturais, uma vez que a alimentação de cada comunidade nos remete aos contextos geográfico, econômico, histórico e às necessidades físicas dos habitantes de cada região.
