13. Módulo de auto-localização para um agente exploratório usando Filtro de Kalman / Self-localization module for exploratory agent using kalman filter
Construir um robô capaz de realizar tarefas sem qualquer interferência humana é um dos maiores desafios da Robótica Move!. Dispondo apenas de sensores, um robô autônomo precisa explorar ambientes desconhecidos e, simultaneamente, construir um mapa confiável a fim de se localizar e realizar a tarefa. Na presença de erros de odometria, o robô não con

17. Proposta de um modelo de confiança para o protocolo OLSR
This work presents a new computational trust model, developed to improve the packets forwarding in MANET using OLSR protocol. Mobile Ad hoc Networks (MANET) are composed of mobile devices that communicate directly without the need of any prior infrastructure. The nodes in these networks operate as routers. The Optimized Link State Routing Protocol (OLSR) is

19. Preparação e padronização de metodologia de marcação in vitroe estudo de biodistribuição do octreotídeo-[Tyr3]-HYNIC/EDDA/TRICINA-[99mTc / PREPARATION AND STANDARDIZATION OF AN IN VITRO LABELING METHODOLOGY AND STUDY OF [99mTc]-EDDA/TRICINE/HYNIC-[Tyr3]-OCTREOTIDE BIODISTRIBUTION
Somatostatine receptors are widely expressed by several tumors, especially of the neuroendocrine origin. In vivo images of these tumors using radiolabeled somatostatine analogues became a useful clinical tool in oncology. The radiopharmaceutical currently applied is [111In-DTPA-Phe1-D]-octreotide. However, the use of indium-111 (111In) is limited by the prod

21. Determinação dos enantiômeros da atropina em soluções oftálmicas empregando a cromatografia líquida de alta eficiência com fase estacionária quiral / Determination of atropine enantiomers in ophthalmic solutions by liquid chromatography using a chiral stationary phase
There are many therapeutic agents commercialized under racemic form. The enantiomers can show significant differences in the pharmacokinetic and pharmacodynamic profiles. The use of pure enantiomer in pharmaceutical formulations can result in better adjustment of dose and less adverse effects. Atropine, an alkaloid of the Atropa belladonna, is a racemic mixt
