This Bachelor’s Thesis of Bachelor of Computer Science defines a research and a network sensor simulation on non-planar surfaces . The report is composed of an introduction of the research, a theoretic study, a state of the art and a historic context of sensor network. The simulation consists of the formation of terrain, node’s random distribution and a production and a transmission of the node’s packages. Based on these three important topics , the exchange of information/packages between multiple nodes is through breadth-first search algorithm. The active nodes, node quantity and operation range are also defined in the program. After the program analysis the node activation, the packages are created and transmitted to the next node. This process occurs many times and help on the analysis of the sensor network on non-planar surfaces parameters

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

Na literatura da área de Ensino de Física encontramos diversos argumentos em defesa da inclusão, nos currículos escolares do Ensino Médio, de conteúdos de Física Moderna e Contemporânea. A Teoria da Relatividade Especial e Geral (ao lado da Mecânica Quântica) é um dos pilares da Física Moderna. Consideramos significativo e oportuno obter um panorama da produção acadêmica sobre o ensino e aprendizagem deste tópico. Nosso objetivo é sintetizar os avanços, as convergências e sinalizar perspectivas, com o intuito de contribuir para um avanço e defesa dos trabalhos futuros. Assim, procuramos resposta para a questão: Quais as contribuições da pesquisa em Ensino de Física para que a Teoria da Relatividade Especial e Geral (TREG) possa ser abordada no Ensino Médio?

The aim of this paper is to point the main research tendencies in teaching and learning English as a foreign language in the main postgraduate courses in this area, in Brazil, in the period 2005-2010. The adopted methodology for the data collection included the inventory of theses and dissertations, which are included in the sites of the universities with research lines in Applied Linguistics and were produced in the mentioned period. The most productive categories were the ones related to teacher formation, translation, language and technology and studies about teachers and students’ beliefs.

Este trabalho objetivou investigar a produção acadêmica sobre o esporte educacional no contexto brasileiro nas principais revistas cientificas da área da educação física, buscando analisar as principais contribuições sobre este campo de pesquisa para o contexto pedagógico da educação física escolar. Para isso foram analisadas as revistas cientificas indexadas na base de dados da CAPES entre os extratos A2 a B2 na área de Educação Física, buscando avaliar quantitativamente o número de trabalhos publicados nos últimos onze anos (2003 á 2014). Além disso, os trabalhos encontrados passaram por uma analise qualitativa, buscando estabelecer categorias temáticas que possam trazer à tona um quadro do delineamento do estado da arte desse campo de investigação no Brasil, na ultima década. Diante disso, o estudo procurou contribuir para um maior entendimento da atual perspectiva relacionada a produção cientifica sobre esporte educacional no Brasil, onde foram encontrados 15 artigos, o que nos permitiu delinear um quadro da educação física escolar atualmente, fazendo alguns apontamentos em relação a direções futuras neste campo de pesquisa. Ainda são necessários muitos estudos para dar subsídios para os professores, porém este é mais um passo pequeno em direção a um futuro com mais possibilidades e reconhecimentos na área

The quantitative and qualitative increasing of researches in Science teaching imposes the periodical mapping need of scientific production about the subject, with a view to identify its own characteristics and tendencies. In this context, researches such as “State of art”, given his executrix character, constitute in modality inquiring that allow us to outline historical scenes for a given area (or subarea) of knowledge. In this light, this work aims to outline the panorama of Brazilian academic production, represented by dissertations and thesis, in evolution teaching between 1990- 2010. The documents susceptible of analysis were raised in three online data basis and its selection happened from the reading of titles, abstracts and key-words with views to identify the dissertations and thesis that truly approached the Evolution Teaching. The found results evidence the predominance of dissertations related to the number of thesis and the concentration of academic production in Evolution Teaching in Brazil south-east region, especially in São Paulo state. In researches trends we verified the prevalence of investigations related to the previous conceptions of students and professors (in all teaching levels) and to teacher training.

Over the past four decades it occurred a great expansion of science education research in Brazil (TEIXEIRA, 2008). Considering the scientific production in the area, descriptive studies, called state of the art are necessary, but little found in Brazilian scientific literature, especially in the field of science education. In this context, this paper identifies and describes the main features and trends of Brazilian research in the field of education in science museums, released in the form of dissertations and thesis, in the period 1970 to 2010. It is a qualitative and quantitative research, which performs a document analysis, in a bibliographical review. We mapped 153 academic researches, mainly in the Rio-São Paulo axis, mostly in the last decade, showing that the area can be characterized as an emerging field in science education.
