Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

985 The Hanford Site in south-central Washington State produced plutonium for the USDOE weapons program from 1943 to 1989. Plutonium (Pu) production involved the fi ssion of uranium fuels using nine nuclear reactors along the Columbia River, followed by the extraction and concentration of trace product Pu through chemically intensive processing regimes performed in the central portion of the si...

<p>Os reservatórios de água para consumo humano permitem garantir reservas nos sistemas abastecimento e gerir variações do consumo. Contudo, a sua configuração os modos operação podem ter implicações na qualidade da distribuída. Este trabalho apresenta uma caracterização dos em Portugal, incidindo nas características físicas operacionais que condicionam o seu desempenho ponto vista mistur...

In 1998, Bedau et al. de ned a set of metrics for characterizing the long-term evolutionary dynamics of a system. They argued that no known arti cial system demonstrates the unbounded evolutionary activity observed in the fossil record. In response we have developed a series of toy models that approach and eventually succeed in demonstrating unbounded evolutionary activity. The underwhelming su...
