The research presents as its central theme the study of the bibliographic record conversion process. The object of study is framed by an understanding of analogic bibliographic record conversion to the Bibliograhpic MARC21 format, based on a syntactic and semantic analysis of records described according to descriptive metadata structure standards and content standards. The objective of this research the objective is to develop a theoretical-conceptual model of syntactic and semantic of bibliographic records, from Linguistic studies of Saussure and Hjelmslev of manifestations of human language, which subsidizes the development of a computacional interpreter, focused to the conversion of bibliographic records to MARC21 Bibliographic Format, which can be confirmed both the semantic value of the informational resource represented as the reliability of the representation. Given the aforementioned objectives, the methodological trajectory of the research is based on the qualitative approach, of an exploratory, descriptive and experimental nature, and with recourse to the literature. Contributions on the theoretical plane can be envisaged regarding the development of questions inherent to the syntactic and semantic aspects of bibliographic records, and by involving, at the same time, interdisciplinarity between Information Science, Computer Science and Linguistics. Contributions to the practical field are identified by the fact the study covers the development of the Scan for MARC, a computational interpreter that can be adopted by any institution that wishes to use the conversion procedure for bibliographic record databases to the MARC21 Bibliographic Format from description and visualization schemes of bibliographic records (AACR2r and ISBD), an aspect of the research which is considered innovative.

The Information Access law, sanctioned in November 18, 2011, regulates the constitutional right of access to public information by Brazilian citizens. Although this law requires the provision of information of public interest, it does not define how such information should be made available. Ideally, information should be in an open format, allowing its use in an efficient and fast way. In the official sites of the federal government the way information is currently available does not allow its reuse as they are presented in dynamic pages from the selection parameters and filters. The objective aim of this paper is to present the system called MDDIR Tool, which proposes ways to persist, represent and retrieve digital information resources generated by the Federal Government official sites. Although this system had been designed for a specific purpose, it may be applied to other fields with similar characteristics. The purpose is to facilitate the access to open data, allowing such data to be consolidated and organized , generating new knowledge and information easy to be interpreted by the general population.

This work aims to kinematic and dynamic analysis of a VW Saveiro in order to estimate the power requested to the engine with the imposed movement conditions. Thus, the study will be the basis to the specification of the electric engine, on the conversion of the internal combustion vehicle into electric one. First of all, a literature review was done in order to understand the state of the art for this issue and come up with the technical features of the vehicle in question. The next step is the identification and calculation of all forces acting on the prototype in motion, from 0 to 120 km/h, in intervals of 10 km/h, under the defined conditions of path and time. Then, were determined the values of the torque and rotation of the components from the transmission system, as well as the engine power, for each speed range. The results show the most influential forces on the resistence of the movement in each speed range, and the behavior of the torque curve is verified. Finally, it was also analyzed the implementation of pinwheels on the frontal area of the vehicle, in order to convert wind energy into electrical energy to supply the lighting subsystem of the vehicle and the proposal was validated. Limiting the maximum speed of the vehicle to 90 km/h, it was finally concluded that the power of the electric engine should be 40 HP

Changes are occurring worldwide, including the area of positioning using Global Navigation Satellite Systems in mobile devices such as mobile phones or laptops. This is due to the great improvement and availability of Internet services to these mobile devices. The accuracy and speed of data transmission for these devices makes the technology of sending / receiving data via an internet targeted for optimization. The optimization could allow obtaining, in real-time, coordinates (latitude, longitude and altitude) of suitable quality for users of GPS (Global Positioning System) devices that have wireless Internet access, such as those used to control the eet, locomotion, navigation, agriculture, etc. . The use of the protocol NTRIP (Networked Transport of RTCM via Internet Protocol) in GPS applications is growing every day. Applications are available in C, which creates an opportunity for development with a focus on multiplatform environments. In this context, we propose an application, implemented in a multiplatform environment and the use of NTRIP, able to run on a mobile device for receiving GNSS data

Energy efficiency is an increasingly important issue due to the current scenario where increasing demand is growing faster than the energy supplied. It is important, therefore, analyze and minimize electrical system losses. This study conducts a comparison of a system formed by a photovoltaic generator feeding an LED lamp directly without steps DC-AC -DC conversion, and a system using these conversion steps for the same lamp power. Losses in conversion steps are quantified and the degradation of power quality occurred due to conversion is evaluated

O Repositório Institucional UNESP foi criado em 2013 e, para sua implantação, foi povoado com dados obtidos de forma automática. Considerando a experiência realizada na UNESP, este trabalho tem por objetivo apresentar os processos utilizados para a conversão dos registros coletados de três diferentes fontes de dados (Web of Science, SciELO e Scopus) para inclusão no repositório. A partir da coleta dos registros, os padrões de metadados da Web of Science, da SciELO e da Scopus foram mapeados para o perfil de aplicação de metadados utilizado no repositório. Os registros foram coletados como arquivos XML e, para sua conversão, foram elaboradas folhas de estilo utilizando a linguagem XSLT. Após essa conversão, os arquivos XML foram convertidos em arquivos CSV e, então, importados no Repositório. Conclui-se que os processos de conversão utilizados permitiram alcançar as metas iniciais do Repositório e evitaram a necessidade de inclusão dos registros de forma manual.
