Use of classification in organizing and searching the web

The traditional characteristics and challenges for organizing and searching information on the World Wide Web are outlined and reviewed. The classification features of two of these methods, such as Google, in the case of automated search engines, and Yahoo! Directory, in the case of subject directories are analyzed. Recent advances in the Semantic Web, particularly the growing application of ontologies and Linked Data are also reviewed. Finally, some problems and prospects related to the use of classification and indexing on the World Wide Web are discussed, emphasizing the need of rethinking the role of classification in the organization of these resources and outlining the possibilities of applying Ranganathan's facet theories of classification.

Estudo da viabilidade técnica, econômica e ambiental da substituição de um banco de resistências elétricas de aquecedores por uma caldeira alimentada por biomassa de paletes residuais na indústria de laminação

Given the increasing demand for fossil fuels to power the engines of the global economy, and also the slow process of synthesis of oil, it becomes necessary to develop new sources of renewable energy in addition to improve promising sources that already exist, turning them competitive. Based on this, biomass is shown very promising between the most popular energy sources due to its availability, applicability, and above all, the fact of not emitting green house gases when analyzing the whole carbon cycle. In this sense, this work presents, through an environmental, technical and economic analysis, the impact in an aluminum mill of replacing the use of electricity, in one process, by a boiler fueled with biomass from waste process of packaging the finished product with pallets. Thus, besides the reduction of CO2 emissions, financial gains are targeted, since the main goal of the corporations that require such power is to maximize its profits

Seleção de motobombas para o setor sucroalcooleiro

This work has the purpose to explain how the sugar and alcohol sector works, detail all the processes which uses pumps and assist in the selection and specification of pumps attached with engines, that will make part in important industry processes in the manufacture of sugar and alcohol. A bibliographic revision about the working of sugar and alcohol sector and about pumps were made to help the analysis of a case. This case had the purpose to analyze the selected pumps that were part of a initial project of an industry which aimed a future expansion. The pumps that were selected to made part of the initial project were over dimensioned and were operating out of the best performance point, making the pumps inefficient because the expansion didn't happened. The solution was to select another pump with bigger performance and less power consumption to have a decrease in the energy consumption and in the operational costs of the industry and using the extra electric energy in the industry or selling it

Projeto de um sistema de aquisição dedados para a planta termelétrica do laboratório de máquinas térmicas do DEN/FEG/UNESP

With the purpose of provide students with the practical contact with the operation of a thermoelectric plant, the steam plant Laboratory College of Engineering Guaratinguetá was restored, this work was undertaken so that the necessary equipment was specified for this steam plant had their instrumented processes, enabling greater precision of the measurements performed in the tests and also storing your information. The instrumentation of the plant is to approximate the practices carried out in the laboratory with real situations encountered in industrial steam plant, thus collaborating with the most comprehensive training of students and ensuring the safety of operations performed in the laboratory

O estudo da usinagem em torneamento da superliga à base de níquel Pyromet 31v

The search for materials with higher properties and characteristics (wear resistance, oxidation, corrosion, etc.) has driven research of various materials. Among the materials that are being studied with such properties and characteristics are super alloys based on nickel which has an important role in the aeronautical, automotive, marine, production of gas turbines and now in space vehicles, rocket engineering , experimental aircraft, nuclear reactors, steam-powered plants, petrochemical and many other applications because besides having all the characteristics and properties mentioned above also have an excellent performance at high temperatures. The super alloy based on nickel studied in this work is the super alloy Pyromet 31v normally used in the manufacture of exhaust valves in common engines and diesel engines of high power by cater requirements such as mechanical strength and corrosion resistance at temperatures of approximately 815 ° C. The objective of this work is to produce results to demonstrate more specific information about the real influence of coatings on cutting tools and cutting fluids in turning and thus promote the optimization of the machining of these alloys. The super alloy Pyromet 31v was processed through turning, being performed with various machining parameters such as cutting speed, feed rate, depth in conditions of Minimum Amount of Fluid (MAF), abundant fluid, cutting tools with coating and without coating in early in his work life and with wear. After turning were obtained several samples of chips and the part generated during the machining process, was measured roughness of the material, subsequently made macrostructural analysis of the tools used order to detect possible wear and microstructural analysis of samples collected being that the latter was used for Optical Microscopy, Scanning Electron Microscopy (SEM) and ...
