1. Caminhada de pessoas com deficiencia visual em areas naturais : um estudo com auxilio do GPS (Sistema de Posicionamento Global) / Walks of people with impairment in natural environment : a study with aids of GPS (Global Positioning System)
This research accomplished 5 walk tasks in natural trails with 16 people with visual impairment, having as hypothesis that they possess satisfactory space orientation to walk alone in natural areas. In the first task, the participants individually located the landmarks and esteemed the accumulated traveled distances. In the second task, they performed the ge

2. O papel das rotas e da obtenção de informações sobre a eficiência no forrageio de dinoponera quadriceps em ambiente natural
In this study, we investigated the role of routes and information attainment for the queenless ant species Dinoponera quadriceps foraging efficiency. Two queenless ant colonies were observed in an area of Atlantic secondary Forest at the FLONA-ICMBio of Nisia Floresta, in the state of Rio Grande do Norte, northeastern Brazil, at least once a week. In the fir

3. Das Minas às Gerais: um estudo sobre as origens do processo de formação da rede urbana da Zona da Mata mineira
The search for the origins, for the way the urban concentration of certain populations have worked provides valuable clues for the comprehension of the present complexity of their network of cities and inspires in those populations a feeling of identification with and appreciation of their local characteristics, allowing for new possibilities for action in r

4. Localização e mapeamento simultâneos com auxílio visual omnidirecional. / Simultaneous localization and mapping with omnidirectional vision.
The problem of simultaneous localization and mapping, known as the problem of SLAM, is one of the greatest obstacles that the field of autonomous robotics faces nowadays. This problem is related to a robots ability to navigate through an unknown environment, constructing a map of the regions it has already visited at the same time as localizing itself on thi

5. Avaliação de Impactos Ambientais: Estudo de Caso das Ações da Petrobrás em Virtude de Acidente de Dois Mil na Baia de Guanabara.
Evaluation of the ambient impact are carried through studies to identify, to foresee and to interpret, as well as prevent the ambient consequences or effect that determined action, plans, programs or projects can cause the health, to human well-being. These studies add alternatives to the plans or projects, as knowledge instruments the service of the decisio

6. Localização de um robô móvel usando odometria e marcos naturais
Diversos métodos de navegação de robôs móveis requerem a medição da posição e orientação do robô no seu espaço de trabalho. No caso de robôs móveis com rodas, técnicas baseadas em odometria permitem determinar a localização do robô através da integração de medições dos deslocamentos incrementais de suas rodas. No entanto, essa técnic

7. Statistical analysis of shape through triangulation of landmarks: A study of sexual dimorphism in hominids
Two objects with homologous landmarks are said to be of the same shape if the configuration of landmarks of one object can be exactly matched with that of the other by translation, rotation/reflection, and scaling. In an earlier paper, the authors proposed statistical analysis of shape by considering logarithmic differences of all possible Euclidean distance
