1. GENERATION AND PERFORMANCE ANALYSIS OF GPS AND GLONASS VIRTUAL DATA FOR POSITIONING UNDER DIFFERENT IONOSPHERIC CONDITIONS
Abstract Several approaches concerning the use in positioning of GNSS (Global Navigation Satellite Systems) can be considered: systems, applied methods and errors that can affect the signals. Following the GLONASS (GLObal NAvigation Satellite System) constellation reestablishment (2011), there was renewed interest in its use with GPS (Global Positioning Syst

2. O contributo de Vilém Flusser para a ética na época da imaginação digital
Resumo O presente artigo pretende demonstrar, a partir da navegação e do naufrágio como metáforas para a existência humana e para o estado atual da civilização ocidental, como o pensamento de Vilém Flusser contribui para uma conduta ética na época da imaginação digital e das imagens técnicas. Flusser é um dos poucos teóricos da mídia e das te

3. Mobile Augmented Reality enhances indoor navigation for wheelchair users
Introduction: Individuals with mobility impairments associated with lower limb disabilities often face enormous challenges to participate in routine activities and to move around various environments. For many, the use of wheelchairs is paramount to provide mobility and social inclusion. Nevertheless, they still face a number of challenges to properly functi

4. Técnica de realidade virtual para manipulação e deformação de superfícies NURBS
The Virtual Reality (VR) mainly deals with the creation of three-dimensional environments generated in real time and made available for multisensory interaction with different devices. A high processing capacity and modeling environments is required for applications of this nature. These applications currently extend to various productive sectors such as ind

5. Utilização de redes neurais de Spikes para tarefas de navegação de agentes robóticos autônomos
Detectar e prevenir possíveis colisões é um dos aspectos mais importantes na robótica móvel. Esta tarefa, embora aparente facilidade quando executada por seres vivos, mantêm sua dificuldade quando modelada e executada por agentes robóticos autônomos. Além disso, roboticistas e pesquisadores têm sempre encontrado na natureza uma fonte inesgotável d

6. uiGloves : uma ferramenta para interação natural através de gestos / uiGloves – a natural interaction method for graph navigation
Esse trabalho apresenta uma ferramenta interativa que foi construída visando obter um novo método de interação natural através de reconhecimento de gestos que pudesse ser utilizado para navegação em grafos. Trata-se de um par de luvas – chamadas uiGloves – que possuem, cada uma, dois LEDs infravermelhos na ponta dos dedos indicador e anelar, que s

7. TÉCNICAS DE NAVEGAÇÃO 3D USANDO O CUBO DE DISTÂNCIAS / 3D NAVIGATION TECHNIQUES USING THE CUBE MAP
The use of 3D viewers is becoming common in several activities. The appearance of new technologies, with the resulting increase in processing power, made possible the creation of larger and richer 3D virtual environments. However, the navigation in 3D environments, especially the multiscale ones, is still a problem for many users. The goal of this work is to

8. Distributed environment in Virtual Reality as support the Cooperative Learning for the Problems Solving / Ambientes distribuídos em Realidade Virtual como suporte à Aprendizagem Cooperativa para a Resolução de Problemas
A great number of researchers believe that problem resolution is inherent from the great part of the teaching and learning processes. It is considered that this methodology presents a better effectiveness when applied cooperatively, in other words, an apprentice improves your acting in solving problems when accomplishes his activity in cooperation with other

9. Wayfinding techniques for multiscale virtual environments
Wayfinding in multiscale virtual environments can be rather complex, as users can and sometimes have to change their scale to access the entire environment. Hence, this work focuses on the understanding and classification of information needed for travel, as well as on the design of navigation techniques that provide this information. To this end, we first i

10. Contribuições das TIC no ensino e aprendizagem de ciências: tendências e desafios / Contributions of ICT to teaching and learning of science: trends and challenges
This work presents a reflection about the NTIC and the teaching of sciences. Specifically it discusses the teachers education and the computer using at the continued teachers education proposal or by using technology sources (computers) in the learning and teaching processes. For that, it was made a research known as knowledge state by analyzing the abstract

11. Synthesis of autonomous controllers in mobile robotics through bio-inspired computing / Sintese de controladores autonomos em robotica movel por meio de computação bio-inspirada
Novel techniques for autonomous robot navigation aim at fulfilling the growing demand for mobile robots in multiple segments of society and in a plethora of tasks. The challenges involved in developing the system which controls the robot allow to say that the intelligence embedded in the current robots is found to be still incipient and limited. In this work

12. Geração de trajetórias para veículos aéreos autônomos não-tripulados
In this work a study on the problem of the trajectory generation for unmanned aerial vehicles is carried through. The main objective is to provide tools of path planning for aerial robots, taking into account some of its main physical constraints of movement. For this, some of the more used techniques for motion planning of grounded robots are argued initial
