1. Comparação entre simulação e sistema real de vibração com dois graus de liberdade
Resumo Na engenharia, compreender corretamente os elementos que compõem os sistemas vibratórios e a física envolvida nestes é fundamental no projeto de estruturas e máquinas, por exemplo. Embora em muitos casos, no estudo de sistemas vibratórios não seja possível analisar o sistema somente com um grau de liberdade, sistemas com dois graus ou mais sã

3. Concrete road barriers subjected to impact loads: An overview
Abstract Concrete barriers prevent vehicles from entering the opposite lane and going off the road. An important factor in the design of concrete barriers is impact load, which a vehicle exerts upon collision with a concrete barrier. This study suggests that a height of 813 mm, a base width of 600 mm, and a top width of 240 mm are optimum dimensions for a co

5. Modelagem e simulação de agentes com aspectos cognitivos para avaliação de comportamento social. / Modeling and simulation of agents with congnitive aspects to evaluate social behavior.
This work was developed considering concepts of four research areas: computer science, cognitive science, information science and social communication. The main contribution here is to define minimally cognitive agents who actively participate in dynamic of information flow interfering on the messages received and are being affected by them. The model consid

6. Avaliação de mancais hidrodinâmicos com descontinuidades geométricas / Evaluation of hydrodynamic bearings with geometric discontinuities
Hydrodynamic bearings are widely used in rotating machines, being the element responsible for the interaction between the rotor and the supporting structure. Therefore, in order to describe the dynamic behavior of the rotating shafts, it is necessary to know the journal bearings characteristics. For this reason, the purpose of this work is to analyze the dyn

7. Controle da velocidade e da direção entre dois veículos agrícolas / Speed and steering control between two agricultural vehicles
One problems of the mechanical harvest of sugar cane is the lack of synchronization between the harvester and field wagon. This problem can causes crop losses as well as reducing operational capacity. The first occurs when the machines are misaligned and part of the sugar cane is thrown out of the wagon. The operational capacity reduce occurring when the mac

9. A case study on testing CMM uncertainty simulation software (VCMM)
Virtual Coordinate Measuring Machines (VCMMs) are software packages aimed at providing uncertainty estimates for tridimensional measurements. Since they deal with metrology data to derive uncertainty estimates, which are to be used for making decisions related to product quality, they must be evaluated. Although there are international standards to deal with

10. The using of modeling and simulation for the performance comparative analysis between functional layout and distributed layout / Utilização da modelagem e simulação para fins de análise comparativa de desempenho entre o arranjo físico funcional e o arranjo físico distribuído
Recently researches related to new production systems have been proposed in the literature since traditional ones can not attend efficiently to the new profiles of market (especially characterized by higher variety and variability of demand). In the distributed layout, one of the proposed in the literature, machines are scattered on the floor to make possibl

12. Software process model simulation using abstract state machines / Simulação de modelos de processo de software utilizando máquinas de estado abstratas
The definition of software process models in software devoloper organizations is a hard work. There are many decisions to be made and approaches used to decision support: what activities should be undertaken, their sequencing, what work products must be developed, among others. The first step is to obtain the process representation, that should be transforme
