Caracterização do meio físico para definição de traçado e manutenção de multidutos na região do Vale do Paraíba

The present study characterizes the physical environment for its fragility and its capacity to support, through geological and geomorphological properties in the study area, concerning primarily with a sustainable environmental planning for the construction and maintenance of buried linear works. The study area is located on a portion of the Paraiba Valley, which is between the latitudes 22 °30' S and 23°00' S and longitudes 44°30' W and 45° 15' W, between cities of Aparecida (SP) and Queluz (SP). The methodology was based in the visual interpretation of TM/Landsat-7 images, using as a criterion the element textural image and its way of organizing space. To do so, it was set five levels of textural density, enabling thus to the partitioning of the area in areas counterparts (Z.H.s). As a result, it was identified 133 Z.H.s. By using the same criterion textural image the following physical properties were classified: Erosion Resistance, Permeability, Plasticity X Brittle, Tropia and Relief Asymmetry for each zone counterpart, and then grouped themselves as they hold all properties equal in Units Geoenvironmental (U.G.s). As a result it was identified 18 U.G.s. The work presents, as a final result, a thematic map with favorable or restrictable sectores to the design of buried linear works. Based on this map, it can be propose traces to buried linear works, analyzing their suitability to the physical environment and reducing the impacts caused to the environment.

Seleção de dietas artificiais para manutenção em laboratório do cupim asiático Coptotermes gestroi (Isoptera: Rhinotermitidae)

O cupim exótico Coptotermes gestroi, pertencente à família Rhinotermitidae, é um dos mais prejudiciais para os humanos, do ponto de vista econômico, causando grandes prejuízos no Brasil, principalmente nos estados de São Paulo e Rio de Janeiro. A manutenção de insetos no laboratório pressupõe o uso de uma dieta artificial nutritiva assim, este projeto, pretendeu selecionar a melhor dieta artificial entre 5 testadas, que fosse adequada para manter essa espécie de cupim. Portanto, foram realizados 5 diferentes bioensaios em arenas compostas por câmaras “ninho”, conectadas a câmaras “alimento” , que continham as diferentes dietas ou Pinus sp., madeira utilizada como controle. A sobrevivência dos cupins e o resultado final foi submetido a uma análise de variância que demonstrou que a dieta composta principalmente por  - celulose foi a que apresentou os melhores resultados e foi considerada a dieta mais eficaz na manutenção dos cupins em laboratório.

Aplicação do lean six sigma na linha de produção de turbinas industriais a vapor

This work evaluates the implementation of Lean Six Sigma into the Steam Turbine’s Blades Manufacturing Process, aiming to improve productivity, quality and operational efficiency. Therefore, several tools have been applied, such as VSM, Spaghetti Diagram, Ishikawa, Pareto, DMAIC, Benchmarking and Control Charts, seeking to propose process improvements, as well as Quality Indicators creation. It was obtained a significant waste reduction throughout the process, achieving a lead time reduction of 42% and 83,41% in transport. Also, were introduced the Lean Thinking concepts, such as pull production and Continuous material flow. At the same time, it was possible to calculate the process capability and the sigma level, evaluating and proposing some improvements

Aplicação de um sistema de monitoramento remoto para auxiliar na manutenção preditiva e preventiva de componentes de uma subestação

The increase in energy consumption in the world has caused the electrical systems becoming ever larger and more complex. Because of that becomes necessary to use special tools to efficiently manage the equipment present in these systems. Nowadays a tool very used is the remote monitoring of assets which works collecting signals using sensors processing these signals and make them available to the system user. So the user can use informations that may assist him efficiently in making decisions when doing a maintenance. The system is technically efficient since it improves the measurement process and enables the asset management of a substation by using advanced technology for that and economically viable especially in cases where the user is subject to monetary loss due an interruption of power supply

Melhoria do processo de reparo por meio da redução de Lead Time em uma empresa de som automotivo

The constant search for improvement and survival of the companies makes essential the utilization of cost reduction strategies and resources optimization. This study had as its objective the utilization of Lean Manufacturing tools for the repair process lead time reduction, in a car audio manufacturer. Performing an action research, the major problems were studied, such as the potential causes and the possible improvement activities, using the DMAIC methodology. An action plan was developed for all involved processes and, as a result, the objective was reached by making a direct impact on the customers’ satisfaction and adding a competitive differential for the company

Análise crítica de contratos técnicos como ferramenta para melhoria da gestão da manutenção

Currently, due to the highly competitive search among industries are becoming more tools for managing product that provides higher availability and therefore profitability. Maintenance as a strategic sector and of fundamental importance in business, it seeks to maximize availability and available resources, minimizing costs and waste, which directly impacts the company's results. The present work has as main objective the review of contracts for maintenance services for companies contracted by a chemical company in the Paraíba Valley, since most of its maintenance services are outsourced, and raise these contracts which are more critical and higher risk to the company's success, thus creating a tool for decision-making by maintenance managers in the act of seeking renewals or new contracts to provide services. As a result after drawing up a standard procedure for contracting of services and a better structuring of the same, we developed a method for the calculation of the criticality of the contracts and based on these calculations, charts were prepared which showed that the current scenario of maintenance contracts the company studied. Thus it is possible to evaluate the contracts which are most critical to the success or failure of the company studied, and also pave the way for further studies on how this criticality of a contract can affect the relationship, the contractor x contracted

Auxílio a tomada de decisão na inclusão de sobressalentes de manutenção em estoque utilizando um sistema especialista fuzzy

In the current economic scenario of constant changes, industries seek to increase their profitability decreasing inventory levels. Maintenance and maintenance management, combined with the inventory management of spare parts, has assumed a position of competitive advantage in business. Stock only what you need has become a difficult decision for managers, who are faced with the lack of models and criteria to assist this decision-making. This work proposes a method which supports decision making, on a MATLAB modeling, using criteria established by an expert and his maintenance workers team, focusing on no regular demand of spare parts. The proposed model was adequate to the needs of the company and the maintenance manager in the decision on the storage

Viabilidade de turbinas eólicas de pequeno porte no Brasil

Facing a global scenario where oil is scarce and the emission of CO2 in the atmosphere is a world concern, the search for new methods of energy production becomes the focus of all countries. Based on these assumptions, the wind power gains highlight and happen to be the most exploited around the world, since this does not produce toxic waste, since it uses the wind, no raw material shortage and its cost and efficiency are increasingly attractive. Taking advantage of the geographical features of Brazil, coastal and territorial extension, this study aims to analyze the feasibility of using wind turbines widely used in Germany, one of the countries with the highest production of energy through wind, in Brazil. In order to increase the energy production without causing more environmental impacts, geographical analyses will be made, and to determine the features and costs of production of this type of energy generation, and at the end of this dissertation, will finish for one of the turbines, Montana, is it feasible to install, however due to the Government's little incentive return is not very expressive. With respect to the turbine Passaat, this is infeasible to install under current conditions
