1. Operating Model and Estimation of the Insurance Premium for an Energy Futures Clearing House in Brazil
Abstract Purpose We propose and analyze a new operating model for an energy futures exchange that could be implemented in Brazil, where there is low liquidity for these contracts. The clearing house temporarily assumes the position of customers who fail to answer the margin call, instead of closing the position, as would normally be done under normal condit

2. THEORETICAL UNDERSTANDING OF MORPHOLOGICAL DISTRIBUTION OF HYDROGEN IN AMORPHOUS CALCIUM SILICATE HYDRATE
Determining the morphological distribution of hydrogen atoms in calcium silicate hydrate phase (C-S-H) is of great concern but challenging. In this work, based on the stoichiometric composition of (CaO)1.7(SiO2)(H2O)1.8, a series of amorphous Ca1.7•Si•(O)3.7-x•(OH)2x•(H2O)1.8-x models are constructed using Monte Carlo method, where x represents the m

3. Comparison between traditional project appraisal methods and uncertainty analysis applied to mining planning
Abstract Long-term mining planning is a complex process which involves a large number of variables and uncertainties. Traditional discount cash flow (DCF) is usually used in the evaluation of mining projects. DCF includes net present value (NPV), internal rate of return (IRR), and profitability index (PI). A sensitivity analysis is usually carried out to eva

4. Reliability of reinforced concrete beams designed in accordance with Brazilian code NBR-6118:2014
Resumo O presente trabalho busca avaliar o índice de confiabilidade atingido pelas vigas de concreto armado dimensionadas de acordo com a norma brasileira NBR-6118:2014 em relação ao estado limite último de flexão. As principais estatísticas das resistências são obtidas por simulações de Monte Carlo utilizando o software ANSYS e a ferramenta probab

5. OUTLIER=GROSS ERROR? DO ONLY GROSS ERRORS CAUSE OUTLIERS IN GEODETIC NETWORKS? ADDRESSING THESE AND OTHER QUESTIONS
Abstract This article has theoretically discussed some points regarding outliers caused by errors in geodetic observations (see consideration made). Comments have also been made on the usual 3σ-rule to identify outliers and its common approachs in the simulation of outliers in geodetic networks. Three simulated experiments have been conducted to verify the

6. An application of Earned Value Management (EVM) with Monte Carlo simulation in engineering project management
Resumo As rápidas alterações no mercado, faz que as empresas, cada vez mais, se orientem através de estruturas de projetos. Assim, um projeto difere de uma atividade rotineira pois é único, sendo gerenciado, e proporcionando benefícios esperados sem custos maiores que o previsto. Logo, deve-se planejá-lo e controlá-lo identificando os desvios entre

7. Feasibility of wood production according to productivity class and rotation criteria
Resumo: O objetivo deste trabalho foi avaliar o efeito da rotação florestal sobre a viabilidade técnica e econômica da produção de madeira de eucalipto para carvão, em diferentes classes de produtividade. Utilizaram-se dados de povoamentos de Eucalyptus cuja área foi estratificada em três classes de produtividade: alta, média e baixa. A cada classe

8. An efficient mechanical-probabilistic approach for the collapse modelling of RC structures
Resumo As estruturas em concreto armado são largamente utilizadas ao redor do mundo. Entretanto, a modelagem de seu complexo comportamento mecânico por formulações numéricas eficientes tem sido marginalmente apresentada na literatura. As formulações eficientes possibilitam a precisa e realista representação dos fenômenos mecânicos envolvidos e sã

9. Risks associated with a double-cropping production system - a case study in southern Brazil
ABSTRACT: This study assessed the risk exposure of the production system of a typical farm in southern Brazil. Five possible production systems were analyzed, combining three crops (soybeans, corn seasons and wheat) in different crop-year combinations, for example: “Summer soybeans followed by corn” and “Autumn corn followed by winter wheat”. Five di

10. Satellite Inertia Parameters Estimation Based on Extended Kalman Filter
ABSTRACT: The moment of inertia parameters play a critical role in assuring the spacecraft mission throughout its lifetime. However, determination of the moment of inertia is a key challenge in operating satellites. During satellite mission, those parameters can change in orbit for many reasons such as sloshing, fuel consumption, etc. Therefore, the inertia

12. Crecimiento de grano tridimensional con partículas móviles usando método de Monte Carlo
ABSTRACT In this paper we present a simulation model of grain growth with moving particles in three dimensions using the Monte Carlo method. The effect of concentration and particle size on grain size was studied. In general, it was possible to observe the migration of the particles towards the grain boundaries and the braking that they produce on the moveme
