13. Impact Damage Analysis with Stress Continuity Constraints Fulfilment at Damaged-Undamaged Regions and at Layer Interfaces
Abstract Low-velocity impacts have a relevant importance for safety of laminated and sandwich composite structures, because they are highly susceptible to damage. In this paper, a 3D cost effective zig-zag model is developed in order to efficiently simulate such impacts. It a priori fulfills the continuity of out-of-plane stresses at layer interfaces, the co

14. Flexible Multibody Dynamics Finite Element Formulation Applied to Structural Progressive Collapse Analysis
Abstract This paper presents a two-dimensional frame finite element methodology to deal with flexible multi-body dynamic systems and applies it to building progressive collapse analysis. The proposed methodology employs a frame element with Timoshenko kinematics and the dynamic governing equation is solved based on the stationary potential energy theorem wri

15. Development of ball mill test for simulation of industrial circuit
Abstract The Bond method for ball mil designing has been used for 60 years. Based on the Work Index test, such method is applied mostly in traditional circuit configuration, which includes multi-staged crushing, followed by rod and ball milling. On the other hand, simulation is a widespread and used technique for comminution, classification modeling, and sim

16. ENERGIA DE BAIXA INTENSIDADE: governos, mercados e instituições no regionalismo energético de América do Sul
Although it is considered to be a priority area of cooperation, the South American energy regionalism shows signs of stalling, evidenced by fruitless negotiations for a South American Energy Treaty. This article explains the paradox that, despite the political will, favorable structural conditions for integration and the creation of ad hoc regional instituti

17. Integración de criterios de desempeños en el mejoramiento energético-ambiental de viviendas sociales existentes en Chile
In Chile, 75% of the existing housing stock was built without energy-environmental considerations. These houses are becoming high energy consumers in the country. Nowadays, it exist different measures to improve the energy efficiency of existing dwellings, but these benchmarks consider only some performance that have implication on the energy demand. Normall

18. Three dimensional Free Vibration and Transient Analysis of Two Directional Functionally Graded Thick Cylindrical Panels Under Impact Loading
AbstractIn this paper three dimensional free vibration and transient response of a cylindrical panel made of two directional functionally graded materials (2D-FGMs) based on three dimensional equations of elasticity and subjected to internal impact loading is considered. Material properties vary through both radial and axial directions continuously. The 3D g

19. State of the art: integrating services for mega events
This paper describes the state of the art of a simplified model for integration of services in mega events. The project context, which was financed by the National Research Council – CNPq, is divided into six major areas or functional groups: Urban Mobility, Tourism, Airports, Security, Energy and Telecommunications. The proposal is described in layers, as

20. Dynamic and static analysis of FGM skew plates with 3D elasticity based graded finite element modeling
The present article deals with static and dynamic behavior of functionally graded skew plates based on the three-dimensional theory of elasticity. On the basis of the principle of minimum potential energy and the Rayleigh Ritz method, the equations of motion are derived in conjunction with the graded finite element approach. Solution of the resulted system o

21. Nonlinear wave transmission and pressure on the fixed truncated breakwater using NURBS numerical wave tank
Fully nonlinear wave interaction with a fixed breakwater is investigated in a numerical wave tank (NWT). The potential theory and high-order boundary element method are used to solve the boundary value problem. Time domain simulation by a mixed Eulerian-Lagrangian (MEL) formulation and high-order boundary integral method based on non uniform rational B-splin

22. Conselho Nacional de Justiça: desenho institucional, construção de agenda e processo decisóriol
After four administrations, a recent analysis of the work by the Brazilian National Council of Justice concludes that "the glass dome has cracked, since the inertia has been broken and taboos have been challenged", thereby injecting new energy into the judiciary system's leading role through its integration into the public arena. This break developed from an

23. Controle preditivo baseado em modelo neuro-fuzzy de sistemas não-lineares aplicado em sistema de refrigeração = : Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant / Model predictive control based on neuro-fuzzy nonlinear systems applied to a refrigeration plant
Refrigeration systems can be found in many different branches of industry and are characterized as great energy consumers with considerable non-linear behavior. Several studies have been developed to promote the reduction of energy costs and to minimize the effects of nonlinearities in these systems. The use of automation and process control, particularly th

24. Study of quantum effects in condensed matter thermodynamics : phase transitions at finite temperature / Estudo de efeitos quânticos na termodinâmica da matéria condensada : transições de fase a temperatura finita
Neste trabalho apresentaremos a extensão dos métodos adiabatic switching (AS), reversible scaling (RS) e integração dinâmica de Clausius-Clapeyron (d-CCI) para o formalismo de integral de tragetória. Desenvolvemos programas de Monte Carlo de integrais de trajetória (PIMC) para implementar esses métodos a fim de incluir efeitos quânticos nos cálculo
