Este trabalho objetiva a descrição da hierarquia de critérios usados para a tomada de decisão em jogos de pôquer. Para tal, o método Analytic Hierarchy Process (AHP) foi escolhido. A modelagem em questão será feita junto a um jogador profissional de pôquer brasileiros de vasta notoriedade. Os resultados obtidos atenderam a expectativa e a hipótese lançada, demonstrando que a posição é fator preponderante, e que a sobrevida na competição não é tão relevante para tomada de decisão. Portanto, o pôquer profissional é um esporte que vai além das probabilidades matemáticas, demonstrando que estratégia e fatores psicológicos influenciam fortemente a decisão.

[EN] Routing protocol for low-power and lossy networks is a routing solution specifically developed for wireless sensor networks, which does not quickly rebuild topology of mobile networks. In this article, we propose a mechanism based on mobility entropy and integrate it into the corona RPL (CoRPL) mechanism, which is an extension of the IPv6 routing protocol for low-power and lossy networks (RPL). We extensively evaluated our proposal with a simulator for Internet of Things and wireless sensor networks. The mobility entropy-based mechanism, called CoRPL+E, considers the displacement of nodes as a deciding factor to define the links through which nodes communicate. Simulation results show that the proposed mechanism, when compared to CoRPL mechanism, is effective in reducing packet loss and latency in simulated mobile routing protocol for low-power and lossy networks. From the simulation results, one can see that the CoRPL+E proposal mechanism provides a packet loss reduction rate of up to 50% and delays reduction by up to 25% when compared to CoRPL mechanism., The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was funded by SIDIA Institute of Science and Technology, by Coordenacao de Aperfeicxoamento de Pessoal de Nivel Superior (CAPES), by Fundacao de Amparo a Pesquisa do Estado do Amazonas (FAPEAM)-support programs (Programa Primeiros Projetos (PPP) and Programa de Tecnologia da Informacao na Amazonia (PROTI)-Amazonia-Mobilidade), by Camara Tecnica de Reconstrucao e Recuperacao de Infraestrutura (CT-INFRA) of Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes(MCTI)/Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq), and by Secretaria de Estado de Ciencia, Tecnologia e Inovacao Amazonas (SECTI-AM) and Government of Amazon State, Brazil.

Production lines normally present a verification step, which is responsible for warning about defective devices. That step, in digital television (DTV) production lines, often includes a tuning and decoding check, which basically verifies if DTV devices are capable of presenting audio and video. However, poor signal conditions may cause unnecessary rejections, which happen due to very hostile environments. Based on that, the present paper proposes a verification methodology that reports poor signal conditions during tuning tests, with the goal of indicating that the associated check must be executed again. Tests, in a real environment, showed that the proposed approach is effective and efficient, while revealed that less than 40% of the obtained rejections, in a target production line, were indeed caused by hardware problems.

The present study analyzes the need of development of the Brazilian Stock Market, considering that a significant presence of this market stimulates a policy of long run economic growth. The fact is that there are several empirical evidences associating more developed economies with a well structured Stock Market.The Brazilian Stock Market's structure must be revised and one of the necessary changes is the requirement of tax norms' alterations, creating a tax system which favors simplicity and fairness.As a form of stimulating the Brazilian Stock Market development, it is proposed to reform the existing taxation norms and also the creation of temporary tax incentives to boost the process of more companies going public, as well as reducing the present tax burden which is imposed on national and foreign investors.
