1. Cost effectiveness of the cancer prevention program for carriers of the BRCA1/2 mutation
ABSTRACT OBJECTIVE: To analyze the cost effectiveness of the diagnostic program for the germline mutation in BRCA1/2 genes and of preventative strategies for the relatives of patients diagnosed with ovarian cancer associated with this mutation. METHODS: The study analyzed the cost effectiveness by developing an analysis of the Markov decision process from

2. QoS management in smart grids: a Markovian approach
In Smart Grids, a variety of new applications are available to users of the electrical system (from consumers to the electric system operators and market operators). Some applications such as the SCADA systems, which control generators or substations, have consequences, for example, with a communication delay. The result of a failure to deliver a control mes

3. Green-Markov models - new optimization strategies: a case study for user allocation in co-channel macro/femto networks
The femtocell concept aims to combine fixed-line broadband access with mobile telephony using the deployment of low-cost, low-power third and fourth generation base stations in the subscribers' homes. While the self-configuration of femtocells is a plus, it can limit the quality of service (QoS) for the users and reduce the efficiency of the network, based o

5. Modelo markoviano de decisão para o roteamento adaptativo em redes WDM totalmente ópticas / Markov decision model for adaptive routing in all-optical WDM networks
As redes ópticas WDM têm sido cada vez mais utilizadas, visto que aproveitam melhor a capacidade de transmissão das fibras ópticas. Com o intuito de evitar conversões óptico-elétricas na transmissão de dados entre os nós da rede, dispositivos capazes de manter a comutação dos sinais no domínio óptico são instalados em cada nó, tornando a rede

6. Transformação de redes de Petri coloridas em processos de decisão markovianos com probabilidades imprecisas. / Conversion from colored Petri nets into Markov decision processes with imprecise probabilities.
The present work was motivated by the need to consider stochastic behavior when planning the production mix in a manufacturing system. These systems are exposed to stochastic behavior that is usually not considered during production planning. The main goal of this work was to obtain a method to model manufacturing systems and to represent their stochastic be

7. Methods for truck dispatching in open-pit mining.
Material transportation is one of the most important aspects of open-pit mine operations. The problem usually involves a truck dispatching system in which decisions on truck assignments and destinations are taken in real-time. Due to its significance, several decision systems for this problem have been developed in the last few years, improving productivity

8. Superdifusão de caminhadas markovianas e não-markovianas. / Superdifusion of marcovian na non-marcovian walk.
Random walks are tools used in statistical physics to quantitatively describe the evolution of dynamical systems. Such systems are ubiquitous in Nature and each system requires a unique approach. Models of the motion of biological organisms are constructed based on the randomness observed in search strategies. Markovian models attempt to faithfully reproduce

9. Planning for multi-robot localization / Localização multirrobo cooperativa com planejamento
Em um problema de localização multirrobô cooperativa, um grupo de robôs encontra-se em um determinado ambiente, cuja localização exata de cada um dos robôs é desconhecida. Neste cenário, uma distribuição de probabilidades aponta as chances de um robô estar em um determinado estado. É necessário então, que os robôs se movimentem pelo ambiente

10. Extração de preferências por meio de avaliações de comportamentos observados. / Preference elicitation using evaluation over observed behaviours.
Recently, computer systems have been delegated to accomplish a variety of tasks, when the computer system can be more reliable or when the task is not suitable or not recommended for a human being. The use of preference elicitation in computational systems helps to improve such delegation, enabling lay people to program easily a computer system with their ow

11. Expoente de Hurst e diagrama de fase para persistência induzida amnesticamente em processos não-markovianos. / Hurst exponent and the phase diagram for persistence induced amnestic on a non-Markovian
Nowadays there has been a growing interest in anomalous diffusion: the super difusive and sub-difusive processes. The problem about normal diffusion already well established whereas many problems still exist in anomalous diffusion. Several mathematical models and computational techniques have been developed to model such processes. In this work we studied a

12. PADRÕES DE CRESCIMENTO E PREDIÇÃO DA ESTRUTURA DIAMÉTRICA COM AUXÍLIO DE BANDAS DENDROMÉTRICAS NA FLORESTA NACIONAL DE CAXIUANÃ - PA
In forest management it is fundamental that those in charge know how to plan the logging activities grounded on statistical tools so they can diminish error margins in important decision making situations. Knowledge about informations of growth pattern and diameter distribution projection leads to optimization of the production process. It is so because thos
