1. CONDITIONAL PRICING MODEL WITH HETEROSCEDASTICITY: EVALUATION OF BRAZILIAN FUNDS
RESUMO Os resultados empíricos na literatura demonstram que a versão condicional do Modelo de Precificação de Ativos Financeiros (CAPM), particularmente no que se refere ao modelo na forma em espaço de estado, no qual o beta é estimado pelo filtro de Kalman, possui maior poder explicativo do que a sua versão incondicional. A maioria das análises emp�

2. An integrated pit-to-plant approach using technological models for strategic mine planning of copper and gold deposits
Abstract The strategic mine plan is a crucial step for the success of mining companies, and for its development, it is necessary to use a number of inter-related variables that are usually estimated independently. These variables include operational data that is traditionally isolated in information islands between the different departments in the mine or th

3. Decomposition approach for generation and transmission expansion planning with implicit multipliers evaluation
In an electric power systems planning framework, decomposition techniques are usually applied to separate investment and operation subproblems to take benefits from the use of independent solution algorithms. Real power systems planning problems can be rather complex and their detailed representation often leads to greater effort to solve the operation subpr

11. Models for estimation of the optimal investment timing in deep-waters projects / Modelos para estimativa do momento otimo de investimento em projetos em aguas profundas utilizando opções reais
This work proposes two Real Options models for economic evaluation of E&P projects located in deep-water. The models consider the effects of uncertainties related to the oil price and the process of technological evolution. These models are useful for undeveloped reserves of heavy oil in deep-water that depict a great level of uncertainty, as the available t
