It was observed the metacognitive trajectory of three users from a public university library the state of Sao Paulo to identify the metacognitive strategies that were used during the process of searching for information in a online collective catalog. Its configuration was based on participants' oral reports obtained by the technique of individual verbal protocol to provide an actual configuration of the task ans a closer examination of its natural recovery of information systems. The data collection sessions were recorded, and the recorded data were transcribed and categorized into four units of analyses: 1- expertise, 2-regulation, 3-assessment of knowledge itself and 4- organization of cognitive process. The results showed that knowledge of meta-cognitive strategies affects the quality of the results obtained in the process of searching for information and interferes in the way it implements retrieval on-line catalog, a fact the emphasizes the need for studies to move forward on issues meta-cognition of users of information.

This project aims to explore the many methods used for the development of recommendation systems to user ’ s items and apply the content - based recommendation method on a prototype system whose purpose is to recommend books to users. This paper exposes the most popular methods for creating systems capable of providing items (products) according to user preferences, such as collaborat ive filtering and content - based. It also point different techniques that can be applied to calculate the similarity between two entities, for items or users, as the Pearson ’s method, calculating the cosine of vectors and more recently, a proposal to use a Bayesian system under a Dirichlet distribution. In addition, this work has the purpose to go through various points on the design of an online application, or a website, dealing not only oriented algorithms issues, but also the definition of development to ols and techniques to improve the user’s experience. The tools used for the development of the page are listed, and a topic about web design is also discussed in order to emphasize the importance of the layout of the application. At the end, some examples of recommender systems are presented for curiosity , learning and research purposes

The Brazilian sign language is a visual-spatial language, manifested through the hands, facial expressions and body, being considered a natural language used by the deaf community in Brazil. Thus, in a school context the knowledge of LIBRAS is fundamental to the interpreter and the deaf student, so, the role of the interpreter in the classroom is to mediate the relationship between teachers and students. The objective of this study is to investigate the importance of the interpreter in the educational process of the deaf child and try to map the possible difficulties found by him in his workspace, under his perspective in the classroom. This is a qualitative study, which had the data collection instrument as an open interview with questionnaire, dealing on issues concerning to the role and practice of the interpreter of Libras in the classroom to support the deaf student in school age. Therefore, participated in the study two interpreters of Libras who works in elementary school classrooms in the city of Jaú. The results shown that the interpreter's role is extremely important for the education of children with hearing impairment, but it's not recognized and many times not accepted by teachers and educational institutions, when its real function is respected

This paper seeks to understand-the process by which the child in kindergarten builds the idea of number. Therefore we developed a qualitative study of phenomenological approach that involved field work in the classroom with children of four and five years. Starting from their real-world contexts, their experiences and using the natural language tasks are designed to help the student to go beyond the already known, analyzing how they thinks and what knowledge they bring their lived experience. By interference carried expanded mathematical ideas acquired. The analysis and interpretation of research data shows that the idea of number is built by children from all kinds of relationships created between objects and the world around them, and the more diverse are these experiences, the greater the understanding opportunities and development of mathematical skills and competencies. It showed also that, in kindergarten, children tread just a few ways to build the idea of number

In this project, the main focus is to apply image processing techniques in computer vision through an omnidirectional vision system to agricultural mobile robots (AMR) used for trajectory navigation problems, as well as localization matters. To carry through this task, computational methods based on the JSEG algorithm were used to provide the classification and the characterization of such problems, together with Artificial Neural Networks (ANN) for pattern recognition. Therefore, it was possible to run simulations and carry out analyses of the performance of JSEG image segmentation technique through Matlab/Octave platforms, along with the application of customized Back-propagation algorithm and statistical methods as structured heuristics methods in a Simulink environment. Having the aforementioned procedures been done, it was practicable to classify and also characterize the HSV space color segments, not to mention allow the recognition of patterns in which reasonably accurate results were obtained. ©2010 IEEE.

This paper presents an Advanced Traveler Information System (ATIS) developed on Android platform, which is open source and free. The developed application has as its main objective the free use of a Vehicle-to- Infrastructure (V2I) communication through the wireless network access points available in urban centers. In addition to providing the necessary information for an Intelligent Transportation System (ITS) to a central server, the application also receives the traffic data close to the vehicle. Once obtained this traffic information, the application displays them to the driver in a clear and efficient way, allowing the user to make decisions about his route in real time. The application was tested in a real environment and the results are presented in the article. In conclusion we present the benefits of this application. © 2012 IEEE.
