1. Numerical Simulation of Debris Flows of the Catastrophic Event of February 2019 in Mirave - Peru
Resumo Os fluxos de detritos são fenômenos geofísicos provocados por chuvas torrenciais, que ocorrem em áreas montanhosas, e se caracterizam pelo desprendimento de materiais de declives e de leitos de rios e seu consequente arraste água abaixo através de bacias e córregos. Os fluxos de detritos carregam consigo, em geral, lodo, água e rochas, e podem

2. Modular modeling approach for FDM printed structures and piezo disks for metamaterial design
Abstract Research in metamaterials has recently gained interest in the field of noise and vibration control. The ability of creating band gap zones with minimum added mass is the main feature behind its success. In addition, the use of 3D printed parts, particularly the Fused Deposition Modeling (FDM), offers a practical solution for manufacturing parts with

3. THERMODYNAMIC ANALYSIS AND MODELING OF BRAZILIAN CRUDE OIL AND ASPHALTENE SYSTEMS: AN EXPERIMENTAL MEASUREMENT AND A PC-SAFT APPLICATION
ABSTRACT Asphaltenes represent the heaviest fraction of crude oils, being recognized by their tendency to self-associate and precipitate. Asphaltene precipitation and subsequent deposition can cause problems in all stages of production. The objective of this paper is to model Brazilian crude oil and asphaltene systems using the PC-SAFT equation of state. Asp

4. Depicting the 3D geometry of ore bodies using implicit lithological modeling: An example from the Horto-Baratinha iron deposit, Guanhães block, MG
Abstract The definition of geological domains is essential for mineral exploration and is traditionally done manually, section by section, in a laborious, time consuming and subjective process, to construct a 3D model. The technique referred to as implicit modeling is an option to model deposits in a fast and practical manner. This article presents the litho

5. Consistency analysis of mechanical properties of elements produced by FDM additive manufacturing technology
ABSTRACT Additive manufacturing (AM) technology refers to the process of producing 3D objects by adding material in successive layers. Fused deposition modeling (FDM) is one of the AM technologies where objects are built by adding layers of melted thermoplastic filament onto the printing surface. Mechanical properties of FDM printed part depend on many influ

8. Modeling of the temperature field generated by the deposition of weld bead on a steel butt joint by FEM techniques and thermographic images.
The aim of this work is to predict the temperature field generated by welding a steel butt joint (API 5L X80). The prediction was modeled by finite element software Abaqus where the subroutine was developed in Fortran so that heat source motion may be included. The motion was based on the Goldak's double ellipsoid. In the model material nonlinearities were i

10. Estudio del impacto en la calidad del aire de las fuentes puntuales en la ciudad de pinar del Río
A study of the impact of stationary sources on air quality on the city of Pinar del Rio, Cuba, using the modeling system MM5-CALMET-CALPUFF was made. The dispersion of SO2, NOx, CO, PM10 and PM25 emitted from 21 sources during 15 days is simulated by the model. This period is representative of the rainy season in Cuba (Summer). The of SO4(2-) and NO3- wet de

11. Escoamento de fluidos complexos e transporte de partÃculas em geometrias irregulares. / Complex fluid flows and particle transport in irregular geometries.
In this work many types of incompressible laminar Newtonian and Non-Newtonian flows are studied. The interplay of these flows with complex geometries was investigated using computational modeling and numerical solution of the conservation of momentum and mass continuity equations. As a first step, the computational modeling of a network of pores was adopted

12. MODELING OF WATER, SEDIMENT AND PHOSPHORUS LOADS IN AN AGRICULTURAL WATERSHED IN SOUTHERN BRAZIL / MODELAGEM DO ESCOAMENTO, DA PRODUÇÃO DE SEDIMENTOS E DA TRANSFERÊNCIA DE FÓSFORO EM BACIA RURAL NO SUL DO BRASIL
Areas under intensive tobacco crop cultivation have been impacting the water balance and increasing soil erosion in Southern Brazil. Application of large amounts of mineral fertilizers, higher than the tobacco requirement, contributes to excessive phosphorus loads in soil and water bodies. The assessment of potential environmental impacts due to changes in l
