14. 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

18. Topics of numbers theory and primality test / Topicos de teoria dos numeros e teste de primalidade
In this work were discussed topics of the theory of numbers and some primality tests. We show properties of whole numbers, and some criteria for divisibility. We also present, beyond the properties of the Common Dividing Maximum and Minimum Common Multiple, geometric interpretations of the same ones. They had been study topics of theory of congruences and fi

21. Modelo da galáxia utilizando contagens de estrelas no infravermelho / Galaxy model by using infrared star counts
The majority of first quantitative models for the structure of Galaxy used the star counts method to explore the most important galactic structure parameters as a whole. Some of the most important models owe to Bahcall \& Soneira (1980), the Besançon group (Robin \& Crezé (1986)), Wainscoat et al. (1992), Ortiz \& Lépine (1993), among others.
