25. PERTINENCE CURVES IN FUZZY MODELING OF THE PRODUCTIVE RESPONSES OF BROILERS
ABSTRACT The selection of the type of fuzzy systems pertinence curve allows a better representation of the mathematical model and a smaller simulation error. We aimed to study the effect of pertinence curves in fuzzy modeling of broiler performance, created in different production systems. For the development and testing of fuzzy models, three commercial avi

26. Developing a stepwise approach to simulate a hammer mill through the Whiten model - the adherence for a gold ore
Abstract Comminution represents a large portion of the capital and operating cost of a mineral processing plant. In 1983, Cohen estimated that comminution processes could account for 30% to 50% of the power consumption of the mill, and typically represents 50% of the operating costs of a mine. Therefore, its optimization is directly related to reduction of t

28. A meta-analysis over geometric modeling simplifications in ENVI-met urban climate simulation
Resumo A modelagem do clima urbano requer a descrição da geometria do ambiente construído, entretanto a complexidade do tecido urbano traz incertezas sobre o formato e localização exata das edificações. Portanto, durante o processo de planejamento, modelos de geometria simplificada podem ser mais apropriados que modelos detalhados. Nessa pesquisa foi

29. Experimentation and modeling of soil evaporation in underground dam in a semiarid region
RESUMO Nas regiões semi-áridas, as altas taxas de evaporação interferem na disponibilidade de água no solo. Normalmente, é difícil medir e modelar a evaporação devido à complexidade dos métodos disponíveis, ao baixo teor de umidade do solo e à baixa concentração de vapor de água no ar. Isso também pode dificultar o monitoramento e a simula�

30. MODELING SOIL WATER REDISTRIBUTION UNDER SURFACE DRIP IRRIGATION
ABSTRACT The main objective of this study was to develop a numerical model to simulate water distribution, and the shape of the wetted soil volume, resulting from a point source irrigation at the ground surface (dripper), given soil hydraulic properties and irrigation system parameters. The mathematical model was developed in Fortran 90 at the Department of

32. Research on Sliding Mode Method about Three-Dimensional Integrated Guidance and Control for Air-to-Ground Missile
ABSTRACT Based on adaptive sliding mode-control and back-stepping design method, an integrated guidance and control method with less calculation is proposed, which is designed for air-to-ground missile during the terminal course in three-dimensional space. The model of the control system with nonlinear and coupling is simplified, then the integrated guidance

33. Influence of film coefficient during multicomponent diffusion – KCl/NaCl in biosolid for static and agitated system using 3D computational simulation
Abstract The influence of film coefficient formed during the diffusion of inorganic salts (NaCl and KCl) in biosolids was studied using a 3D computer modeling by Finite Elements Method (FEM) in COMSOL Multiphysics® software combined with SOM-type Artificial Neural Networks (ANN). Such tools have shown that the influence of the film formed in the biosolid/s

35. Towards the Brazilian Space Program Modeling Through the Combination of Stakeholder Theory and System Dynamics Methodology
Abstract: In the last 50 years, Stakeholder (STH) theory has become one of the main instruments of analysis, identification, classification and management of entities in the complex and conflicting corporate environment. In a similar way, System Dynamics (SD) methodology has been used as an instrument for modeling and simulating the dynamics of complex syste

36. Incertezas na simulação hidrológica em pequenas bacias por meio do modelo SWAT
ABSTRACT Hydrological modelling is one of the main tools in water resources management application. However, several factors make it difficult to extrapolate the estimated parameters in basins with large contribution areas to smaller basins. This research analysed the uncertainties of flow simulations in small basins. The methodological process involves the
