3. Inclusão de MRI e informação multigrid a priori para inferência bayesiana de fontes de M/EEG / MRI image and multigrid a priori information for bayesian M/EEG source localization
Functional Neuroimaging has evolved in the last few decades with the introduction of techniques such as Positron Emission Tomography or PET and Functional Magnetic Ressonance Image or fMRI [Belliveau et al., 1991]. These allow observing brain activity with a resolution of a few millimeters and, due to the nature of the signal, a time resolution of the order

4. Image matching and classification for UAV navigation.
Unmanned aerial vehicles, known as UAVs, have evolved over the past two decades to sophisticated aircraft robots able to carry out surveillance, recognition, remote sensing and even attack missions. But there are not many alternatives of autonomous navigation systems for most of these aircraft which still require human intervention to navigate. Devices such

5. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

6. Outdoor mapping using mobile robots / Mapeamento de ambientes externos utilizando robôs móveis
Autonomous mobile robotics is a recent research area that focus on the construction of mechanisms capable of executing tasks without a human control. In general, mobile robotics deals with three fundamental problems: environment mapping, robot localization and navigation. Without these elements, the robot hardly could move autonomously from a place to anothe

9. Redes neurais artificiais aplicadas ao problema da localização em ambientes fechados
This thesis addresses the indoor location problem using on artificial neural networks-based techniques. In this system, the received signal strength information (RSSI) provided by standard network wireless interfaces are the basis for mobile devices location prediction. Traditional methods of indoor location have several undesirable characteristics, such as

10. Monitoração e localização de defeitos na soldagem TIG utilizando técnicas de espectrometria
There is an effort made by industries to improve product quality and production methods, and to decrease the production costs. Welding is one of these processes. There are several studies about controlling or monitoring the welding process. This work presents a on-line non-intrusive monitoring system capable of detecting TIG weld defects. In this way, inspec

11. Auto-localização e construção de mapas de ambiente para robôs móveis baseados em visão omnidirecional estéreo. / Simultaneous localization and map building for mobile robots with omnidirectional estereo vision.
This project aims the development of a system for self localization and environment map building for mobile robots in a structured environment. The map is built from images acquired by an omnidirectional stereo system with a hyperbolic double lobed mirror. From a single acquired image, using stereo vision algorithms, the environment around the robot is tridi

12. 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
