1. Dynamic structural response characteristics of new concept blast walls under hydrocarbon explosions
Abstract Offshore installations activities entail the hazard of explosion accidents with potentially severe consequences to safety of workers, integrity of system, pollution of the environment, and economic losses. Blast walls are generally used for the purpose of reducing the explosion consequences. This study introduce a new concept of blast wall (perforat

2. Geometric optimization associated with the use of high-strength concrete in viaducts
Resumo O Brasil carece de investimentos em infraestrutura rodoviária, uma vez que este é responsável por mais da metade do volume de cargas transportado no território nacional. Quando se aborda o tema de infraestrutura rodoviária, uma das principais variáveis é, sem dúvida, a construção e a manutenção de viadutos. Viadutos em concreto de longarin

4. Risky assets performance measures analysis: a study of potential investment, Sharpe ratio and generalized Sharpe ratio indexes. / Análise de medidas de desempenho de ativos de risco: um estudo dos índices de potencial de investimento, Sharpe e Sharpe generalizado
This master dissertation studies and compares the characteristics of Sharpe ratio and its variants, SRc and SRd, generalized Sharpe ratio (GSR) and investment potential (IP), both GSR and IP associated to any utility function. By the fact that GSR and IP are identical indexes, empiric tests were conducted between SRc and GSR. The indexes were evaluated theor

5. VALIDATION OF THE PROJECT VALUATION CRITERION USING THE REAL OPTIONS THEORY: BRAZILIAN OIL FIELDS E&P, CONSIDERING PRICES AS GEOMETRIC BROWNIAN MOTION / VALIDAÇÃO DO CRITÉRIO DE AVALIAÇÃO DE PROJETOS UTILIZANDO A TEORIA DAS OPÇÕES REAIS: E &P DE CAMPOS DE PETRÓLEO NACIONAIS, SUPONDO PREÇOS COMO MOVIMENTO GEOMÉTRICO BROWNIANO
Financial researchers have discussed a lot about the theoretical advantages of including the managerial flexibility and the financial options analogy in projects valuation criteria. Plenty of authors criticize the currently used investment analysis methods, mainly represented by the discounted cash flow, supported by the notion that the managers should use t

6. Efeito do Tipo de GÃs de ProteÃÃo Sobre o Desempenho do Arame Tubular AWS E71T-1, Utilizando Processo Convencional e Pulsado / The effect of the shielding gas type on performance of the AWS E71T-1 flux cored wire using the conventional and the pulsed process
O arame tubular AWS E71T-1 tem sido utilizado, na grande maioria das aplicaÃÃes, com CO2 e argÃnio. No entanto, para esta mistura de gÃs, as informaÃÃes nÃo foram levantadas, de forma suficiente, com relaÃÃo ao desempenho operacional do arame. Sabe-se que o tipo de gÃs afeta tambÃm a transferÃncia metÃlica, o comportamento do arco, a geometria d

7. Uso de imagens Radarsat-1 para fins de mapeamento de uso da terra e cobertura do solo em ambiente tropical úmido urbano: o caso de Manaus, Estado do Amazonas. / Use of radarsat-1 data in the identification of targets related to land use and land cover in urban humid tropical region: the case of Manaus, state of the Amazon, Brazil
The use of remote sensing data acquired through Synthetic Aperture Radar has been a recent common trend for land use and land cover mapping purposes. The information derived from this kind of data has been applied to distinct related application fields, such as: urban pattern analysis and mapping, settlements identification, urban change detection and even m
