13. Design of a passive nonlinear observer and a backstepping controller for surface vessels. / Projeto de um observador passivo não-linear e de um controlador backstepping para navios de superfície.
Dynamic Positioning Systems (DPS) are control systems used to maintain the vessel on a desired position or pre-defined path exclusively by means of active thrusters. A DPS can be separated into a set of dedicated modules with designated tasks. The most significant modules are the position and heading measurement systems, the state estimator, the controller a

14. Posicionamento por GPS na região brasileira durante a intensa tempestade geomagnética de 29 de outubro de 2003
The error due to the ionosphere in the GPS observables depends on the Total Electron Content (TEC) in the ionospheric layer. The TEC varies regularly in time and space in relation to the sunspot number, the season, the local time, the geographic position, and others. However, the TEC can suffer abrupt modifications in its behavior due to the occurrence of in

16. Mecanização de central de navegação inercial com dados a partir da integração de IMU MEMS e receptor GPS / Inertial navigation mechanization through the intergration of an IMU MEMS and a GPS receiver.
The proposal of this work is to present a procedure for integration of the acceleration and angular rate measurements of a low cost Inertial Measurement Unit (IMU) based on MEMS (Micro Electro-Mechanical System) technology with position and speed data from a GPS receiver. Then, it details the equations that have been used to integrate the movement and the at

17. Energia, meio ambiente e economia: o Brasil no contexto mundial
The cycle of fossil fuels as an energy source for mankind is approaching its end. Finite resources, coupled with greenhouse gas, have led to an increased effort in the search for alternative renewable energy sources. Brazil has a leading position, due to a 46% participation of renewable sources in its primary energy supply, compared to the global average of

18. Gestão de estoques de produtos siderúrgicos semi-acabados utilizando uma abordagem híbrida de otimização e simulação
The inventory management is a vital subject witch frequently absorbs substantial part of the budget of an organization. As they do not add value to the product, as less inventories a productive system use more efficient it will be. However the current competitive environment, with the strong presence of global payers, forces the operational costs reduction,

19. Rede ZigBee gerenciada por sistema de monitoramento remoto utilizando TCP/IP e GPRS / ZigBee network managed by remote monitoring system using TCP/IP e GPRS
Este trabalho propõe a integração de técnicas de sensoriamento dinâmico, redes de dados sem fio e internet. A implementação dos nós da rede visa permitir o monitoramento de objetos que se movem tanto numa rede interna, limitada a uma edificação, quanto numa rede externa, através de coordenadas GPSs (Global Position Systems). A rede sem fio, que ut

20. The history desertion : the postmodernism and neoliberalism and ideological sources of global capitalism / A deserção da historia : o pós-modernismo e neoliberalismo como armas ideologicas do capitalismo global : um mal estar mais que um ruptura
It is about a philosophical study developed at the Study Group in Philosophy and Education PAIDEIA, in the Research Line "Politics, Ethics and Education" on the thematic of the historic loss of value in the self-proclaimed "post-modern" theories. The loss of meaning and historical references sounds like a disdain to the past. The intellectual fragility of th

21. AGRICULTURE OF PRECISION: MANAGEMENT OF THE FERTILITY WITH APPLICATION OF THE VARIED RATE OF FERTILIZERS AND ITS RELATION WITH CROP YIELDS / AGRICULTURA DE PRECISÃO: MANEJO DA FERTILIDADE COM APLICAÇÃO A TAXA VARIADA DE FERTILIZANTES E SUA RELAÇÃO COM A PRODUTIVIDADE DE CULTURAS
The agriculture of precision has been an important tool for the characterization of the spatial variability of soil attributes and crops. Thus, there is many options to elaborate thematic digital maps that can improve the soil and crop management. In this work, two croplands that has been managed with precision agriculture during several years were selected.

23. THE SPACE CONSTRUCTION BY TOURISM: GASTRONOMIC TOURISTIC ROUTE OF SANTA MARIA AND SILVEIRA MARTINS / A CONSTRUÇÃO DO ESPAÇO PELO TURISMO: ROTA TURÍSTICA GASTRONÔMICA DE SANTA MARIA E SILVEIRA MARTINS, RS
Tourism is a phenomenon conveyed in the feasibility of transforming and reorganizing geographic space. Tourism reassures cultures and social values, strengthens environmental notions and creates mechanisms to make the economy of a specific place more dynamic. In order to unleash this net of relationships, Tourism needs the articulation among public policies,

24. Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN
Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work
