Gerenciador de estudos para dispositivos móveis: aplicativo do aluno

The project is a platform for education that provides a way where teachers can create and share educational content for their classes, and students can download that content to refer to it at any time. The solution is based on two Windows Phone 7 Apps: Kookaburra Teachers, where teachers can add content to their classes, and Kookaburra Students, where students can download and view the content of classroom. To realize the communication between these two applications, we use a Windows Azure server, that server is also responsible for processing some conversions, enabling real-time translation. In addition to storing all the content that is generated during the lessons

Desenvolvimento de sistemas orientado a modelos

The Software Engineering originated with the motivation to mass produce components for increased productivity in production systems. Since its origins, numerous studies have been proposed on the subject as new features in the creation of systems, like the Object- Oriented Programming and Aspect-Oriented Programming, have been established and methodologies have been developed to control them efficiently. However, years of studies in the area were not sufficient to create a methodology for reusing software artifacts really efficient and easy enough to be widespread. Given this, the Model-Driven Development (MDD) is trying to promote it using the modeling of systems as a reference, becoming part of it and establishing a huge productivity gain. One of his approaches is called Model-Driven Software Development (MDSD), which focuses on improving the practices and systems development using Domain-Specific Languages (DSL) for this purpose. In this Final Paper, Xtext is used as a tool to prove the productivity and efficiency of this approach, and for that bibliographic studies were made on the approach and the tool, and show the methodology and a case study to demonstrate results and conclusions regarding this work

Ciências no ensino infantil: contribuições da introdução de atividade lúdicas e investigativas para o processo de ensino e aprendizagem

Here we present the introduction of a range of science´s experimental activities, designed and developed with a focus on the investigative methodology in an interdisciplinary context. The activities have as main theme water and covers topics of heat and temperature, density and states of matter. The relevance of this project is to promote the first contacts of children with Science in an attractive way, and correctly of the scientific point of view, respecting the cognitive level of each child, trying to stimulate the development of hypotheses, creativity and critical thinking, as well as the development of the narrative, descriptive language and drawing. We developed seven lesson plans that were applied in the year of 2012, during three weeks in a school for early childhood education in the city of Bauru. The activities were conducted with fifteen children aged four to six years old together with the teacher responsible for the group. As main contributions in the teaching learning process we cite: acquiring of new vocabulary, progress in the development of hypotheses, development of collective work, evolution of knowledge of the topics covered, and use of the acquired knowledge to new problems and situations

Web Service para geração de VRS no contexto de posicionamento GPS

Internet is fully inserted in contemporary society, specially in relation to entertainment services and trading. Its reach has transposed the traditional desktop computer models coming to mobile devices like cell phones and GPS receivers. Likewise, the scientific community takes its benefits, both for publication of studies and for communication between clusters processing information, such as at LHC, located in Switzerland. Concerning geodetic positioning, researches in the area present the concept of Virtual Reference Stations - VRS, in which is necessary a communication way between the real reference stations and a central system as well as between central system and a service requester. In this work, we analyze the current solutions for generation of VRS with regard to data delivery for the service requester and present a solution based on Web Services as an alternative to the model being developed by Spatial Geodesy Study Group – GEGE/FCT/UNESP. Comparing solutions, it was verified the potential of Web Services to aid in researches of geodetic positioning using VRS. Using such technology, it is obtained interoperability, providing greater flexibility to develop client applications, both development carried out by researchers of the university or by any person or enterprise wishing to use the service

A presença das mulheres nas ciências exatas

Most well-known and studied names in schoolbooks are men's. It gives one the idea that the world of numbers does not belong to female individuals. In order to verify that this thought is a misconception, a research is carried out about women who, despite all prejudice, have faced many adversities, leaving us many contributions on exact sciences and being relevant until the present date. Nowadays, there is not as much sexual discrimination. Women’s under-representation in exact sciences is due to other motives, such as issues of choice and the option of part-time jobs for professional/familiar balance. Maybe because of this, women have little acknowledgment, as it can be seen in Nobel Prize, where of its 851 awards, only 44 were for women. They are present at different degrees of education, such as licentiate graduation, bachelor’s or master’s, but still outnumbered. The number of female graduates was higher than male’s, according to collected data from Mathematics licentiate graduation Department from 2000 until 2012 in UNESP, Guaratinguetá campus

Uso de algoritmos genéticos na otimização do sistema de coleta do palhiço de cana-de-açúcar

The Brazilian government has convinced the world that ethanol deriving from sugar cane is a promissory means of sustainable fuel for vehicles. There is a great growth of ex vehicles , i.e, run both by ethanol and gasoline, due to competent automotive industries and e cient alcohol production technology. In 2009 and 2010 the ethanol production was 25.7 billion liters and 53.8% of sugar cane production was destined to alcohol production. Nevertheless, the sugar production also derived from sugar cane should increase in 2011. Brazil produced 33 million tons of sugar in the last harvest. With sugar cane on the rise production is arising new environmental problems. The harvest using mechanized cut besides improving the logistic transportation system leaves the generating residue in the eld. This residue is a mixture of straw, leavings and scrap of sugar cane named sugar cane crop residue and corresponds to 30% of biomass and can be burned and produce electricity by cogeneration. But the transport the sugar cane crop from the eld is expensive due costs involved in the transport system. This work aims to propose a formulation for the bales collecting problem from sugar cane eld to mill that minimize the costs involved in the transport system. The computational tests use the C++ language and an algorithm based on genetic algorithms techniques

Utilização do protocolo anycast em ambientes virtuais distribuídos visando à escalabilidade do sistema

Distributed Virtual Environments (DVE) allow multiple users interact with a virtual world by sharing, manipulating objects. Each user has his/her own vision of this world and every changes of state of the environment are distributed among other users. Due to technological constraints, most systems for distributed virtual environments support a limited number of users. The major limitation for development of DVE scale are imposed by the communication system. As the number of users grows, the amount of bandwidth required to exchange information in real time among stations to upgrade the environment and keep it in a consistent state for all connected users. Based on this situation is proposed a framework that uses the protocol anycast in the application layer that provides a load balancing among servers in the region and aims at reducing the latency of message delivery between participants selecting the DVE server best suited for the region participant to connect to the environment

The concepts are used to develop applications to solve problems involving Principal Components Analysis (PCA), which are executed in a Beowulf cluster. The results are compared to the ones of an analogous application with sequencial execution, and then it is analized if there was any performance boost on the parallel application

Um método para reconstrução de superfícies baseado em nuvem de pontos visando representações em multirresolução

The representation of real objects in virtual environments has applications in many areas, such as cartography, mixed reality and reverse engineering. The generation of these objects can be performed in two ways: manually, with CAD (Computer Aided Design) tools, or automatically, by means of surface reconstruction techniques. The simpler the 3D model, the easier it is to process and store it. Multiresolution reconstruction methods can generate polygonal meshes in different levels of detail and, to improve the response time of a computer program, distant objects can be represented with few details, while more detailed models are used in closer objects. This work presents a new approach to multiresolution surface reconstruction, particularly interesting to noisy and low definition data, for example, point clouds captured with Kinect sensor

Aplicando Métodos de Mineração Visual de Texto em conteúdo de Fórum de Discussão

We are included in a society where the use of the Internet became very important to our everyday life. The relationships nowadays usually happen through technological devices instead of face to face contact, for instance, Internet forums where people can discuss online. However, the global analysis is a big challenge, due to the large amount of data. This work investigates the use of visual representations to support an exploratory analysis of contents in messages from discussions forums. This analysis considers the thematic and the chronology. The target forums refer to the educational area and the analysis happens manually, i.e. by direct reading message-by-message. The proprieties of perception and cognition of the human visual system allow a person the capacity to conduct high-level tasks in information extraction from a graphical or visual representation of data. Therefore, this work was based on Visual Analytics, an area that aims create techniques that amplify these human abilities. For that reason we used software that creates a visualization of data from a forum. This software allows a forum content analysis. But, during the work, we identified the necessity to create a new tool to clean the data, because the data had a lot of unnecessary information. After cleaning the data we created a new visualization and held an analysis seeking a new knowledge. In the end we compared the new visualization with the manual analysis that had been made. Analyzing the results, it was evident the potential of visualization use, it provides a better correlation between the information, enabling the acquisition of new knowledge that was not identified in the initial analysis, providing a better use of the forum content

Educação do campo e ensino de ciências: Desafios e propostas a partir de princípios agroecológicos

Com o fenômeno da Revolução Verde a partir da década de 1950, o campo brasileiro sofreu grandes modificações como o incentivo a mecanização pesada e o investimento em insumos agrícolas, como fertilizantes e agrotóxicos. O processo de transformação politica e adoção do liberalismo pelo governo ditatorial incentivaram ainda mais a agricultura baseada no modelo da Revolução Verde e também fez ocasionou grandes transformações na educação. Com a redemocratização, tanto a educação como o campo, passaram a ser discutidos intensamente, no governo e nos movimentos sociais. A partir da Constituição Brasileira de 1988, foi elaborada a Lei de Diretrizes e Bases da Educação Nacional (LDBEN 9394/96) e seu artigo 28 dispõe sobre a educação do campo. Porém, somente em 2002, as escolas do campo passaram a ter uma legislação especifica, reconhecendo as particularidades da educação para camponeses. Em 2008, o Governo do Estado de São Paulo lançou a Proposta Curricular com o objetivo de organizar o sistema educacional e, com isso, todas as escolas da rede estadual seguem o mesmo currículo e material didático. O objetivo dessa pesquisa foi analisar os conteúdos do material didático destinado ao 6° ano do Ensino Fundamental da disciplina de Ciências e avaliar se esses conteúdos atendem a perspectiva da educação do campo em uma comunidade no interior de São Paulo e elaborar uma proposta de material didático complementar, embasado nos princípios da agroecologia. Este trabalho apresenta os resultados da pesquisa, realizada junto ao Movimento dos Trabalhadores Rurais Sem Terra – MST, em que se constatou que o material do governo não apresenta nenhuma especificidade ou adequação para os estudantes e escolas do campo e apresenta um material que pode contribuir para a formação desses estudantes

PGCP - Plataforma para Gerenciamento Colaborativo de Projetos

Collaborative Systems are designed to support individuals in order to solve a problem together, or cooperatively (or collaboratively). Such systems have the advantage of not requiring the presence in the same location of the participants. The basis of any Collaborative System is communication, where users interact with each other in order to exchange information. Communication among individuals is accomplished through collaborative tools such as chat, email, document repository, etc.. Using these tools, companies can reduce operational costs, saving on travel and accommodation of its employees to attend meetings. The project members only need a computer with internet access to use collaborative tools. Project management is essential to the quality of the nal product. To perform a proper management, methodologies must be applied using methods, tools and procedures. There are some phases that are considered generic for all software process models, they are: de nition, development, maintenance and activity to support the software process. In this paper is described a platform for project management using the concepts and features of Collaborative Systems. The goal of this platform is to unify various collaborative tools (such as chat and document repository) in a project management system. Using the system, it becomes possible to manage projects, and the ability to maintain an active constant communication between members of each project
