Topographical surfaces can be represented with a good degree of accuracy by means of maps. However these are not always the best tools for the understanding of more complex reliefs. In this sense, the greatest contribution of this work is to specify and to implement the architecture of an opensource software system capable of representing TIN (Triangular Irregular Network) based digital terrain models. The system implementation follows the object oriented programming and generic paradigms enabling the integration of various opensource tools such as GDAL, OGR, OpenGL, OpenSceneGraph and Qt. Furthermore, the representation core of the system has the ability to work with multiple topological data structures from which can be extracted, in constant time, all the connectivity relations between the entities vertices, edges and faces existing in a planar triangulation what helps enormously the implementation for real time applications. This is an important capability, for example, in the use of laser survey data (Lidar, ALS, TLS), allowing for the generation of triangular mesh models in the order of millions of points.

This paper aims to survey data to analyze the productive capacity of a machining process of rolling bearings by methods-time measurement, in order to identify its bottlenecks and propose improvements in the system. The production times at the company are not known, the method of separation of operations and identification of its activities and the timing of production times and setup become points of departure for this paper. The results from this method of analysis provide clarity in identifying system weaknesses and by them it was possible to carry out the proposals for improvement in some process steps. The implementation of the improvements was not performed, but with the goals of this work was made possible to raise relevant information of the analyzed system

The competitiveness among global markets, the constant need for reducing manufacturing costs and also the growing environmental commitments are fueling the development of techniques for recovery residual parts generated by industrial processes. Among the various areas of a company, we highlight those that involve the processing of raw materials derived from oil, such as polymers (resins), which may take centuries to decompose in the environment and also present as a economic and environmentally strategic point. Thus, this study would examine the recovery of waste polypropylene, from the injection process of a major multinational in the field of home appliances through the recycling by a process comprising the milling, extrusion and chipping of waste material. Easy to deploy, this proposal aims to reduce levels negligible disposal (scrap) of these residues as well as the reintegration of the production process into pieces no visual and no structural importance, aimed at cutting costs and reducing environmental impacts caused. After the survey data in kilograms of waste material generated in a given period of time, and the study of changes in material properties, it would enable the reuse steadily in the injection process

The present research aims to identify conceptions that teachers and students of the early years have in relation to the disciplines of history and geography. The site chosen for the survey was a municipal school in the city of Lençóis Paulista, in São Paulo. The work's theme was chosen after observing a minimization of the teaching of the contents of the above-mentioned disciplines at the expense of mathematical content and mother tongue. In addition, there were difficulties arising from the standardization of education , such as teaching network uses material apostilled . The survey data , together with literature review was conducted with students and teachers in the early years who participated in a semistructured interview . Authors like Callai (1999 and 2005), Cavalcanti (2005 and 1998) and Burke (1992) theoretically supports the research . They have in common a new conception of education that values the small deeds that result in major events. The student, in this view, plays an important role as a subject of social transformation. The research has favored both the analysis of the conceptions of teachers and students, assisting in reflection on teaching practices, but also led to reflect on the training of teachers. The research shows us that the type of material used and the practice adopted may impair the access of students to the language of nature and society

This work aims to investigate the presence of algebra in Brazilian school legislation, from 1980 to the present day. The research was developed through qualitative research, with phenomenological approach, using hermeneutic procedures for the analyzes of legal texts. Survey data were obtained through a survey about the educational legislation, specifically referring to the elementary school, guided by the question how is the presence of algebra in brazilian school legislation that organizes the elementary school?. In possession of the data, the analyzes were carried out considering the historical, social and political environment in which the laws were introduced, focusing the educational landscape of the time, as well as the movements that influenced the teaching of mathematics in the country. The analysis of each text -law were arranged in a row explanatory tables of a meta understanding about the observed. The meta understanding of the documents was drawn up on the basis of the convergence of analyzes that resulted in nuclear ideas of the law texts. At the end a comprehensive synthesis is presented, outlining the movement in which algebra is inserted in schools, through the educational legislation
