1. Accuracy of Nonlinear Formulation of Broiler Diets: Maximizing Profits
Nutritionists need to make commercial decisions about the optimal nutrient content broiler feeds. In order to demonstrate that broiler prices may influence dietary nutrient density, this study developed quadratic feed intake and weight gain equations, according to broiler sex and feeding phase, to be applied in a nonlinear feed formulation model. Four hundre

2. Using Common Features to Understand the Behavior of Metal-Commodity Prices and Forecast them at Different Horizons
The objective of this article is to study (understand and forecast) spot metal price levels and changes at monthly, quarterly, and annual horizons. The data to be used consists of metal-commodity prices in a monthly frequency from 1957 to 2012 from the International Financial Statistics of the IMF on individual metal series. We will also employ the (relative

3. Refinery production planning and scheduling: the refining core business
Intelligent production planning and scheduling are of paramount importance to ensure refinery profitability, logistic reliability and safety at the local and corporate levels. In Brazil, such activities play a particularly critical role, since the Brazilian downstream model is moving towards a demand-driven model rather than a supply-driven one. Moreover, ne

5. Investigating the dynamics of the asymmetry the brazilian gasoline prices: a time series approach. / Investigando a dinâmica da assimetria nos preços da gasolina brasileira: uma abordagem de séries temporais.
This work has the objective to present an econometric analysis of the prices in the Brazilian retail gasoline market, highlighting a non-linear adjustment with the international oil prices and Brazilian exchange rate. In the theoretical part the co-integration analysis with asymmetric error correction models TAR and M-TAR are exposed. Besides, is shown that

6. Three assays on the sector of basic sanitation: Technology of production and efficiency, demand and economic regulation / TrÃs ensaios sobre o setor de saneamento bÃsico: TÃcnologia de produÃÃo e eficiÃncia, demanda e regulaÃÃo econÃmica
No primeiro ensaio deste estudo estima-se uma fronteira estocÃstica de custo translog para o setor de saneamento bÃsico do paÃs, com o objetivo de verificar as propriedades inerentes à tecnologia de produÃÃo e, ainda, estimar o grau de ineficiÃncia tÃcnica presente no setor. Constata-se que o setor nÃo opera com retornos crescentes de escalas, alÃm

7. Modeling the stylized facts in finance through simple nonlinear adaptive systems
Recent work on adaptive systems for modeling financial markets is discussed. Financial markets are viewed as evolutionary systems between different, competing trading strategies. Agents are boundedly rational in the sense that they tend to follow strategies that have performed well, according to realized profits or accumulated wealth, in the recent past. Sim
