in this article effects of friction stir welding (fsw) tool rotational and traverse speeds were studied on heat generation and temperature distribution in welding zone of aa1100 aluminium alloy. computational fluid dynamics method was used to simulate the process with commercial cfd fluent 6.4 package. to enhance the accuracy of simulation in this study, the welding line that is located workpie...

by new advancements in vehicle manufacturing vehicle quality evaluation and assurance has become a more critical issue. in present work, the vibration transfer path analysis and vibration path ranking of a car interior has been performed. the method is similar to classical multilevel tpa methods but has distinct differences. the method is named vivs which stands for vehicle interior vibration s...

background: simulation can be used for educating, evaluating and assessing psychometric properties of an instrument. the aim of this study was to contextualize and assess the validity and reliability of the interprofessional collaborative assessment tool (icar) in an iranian context using simulation.   methods: in this descriptive study, contextualization of the icar was assessed through severa...

In this brief article I identify and characterize the variety of simulation methodologies relevant to political science research. Having identified them, I then recount a lighthearted tale of one successful application of a computer simulation to a real world problem of enormous significance. Extending the discussion to other examples, I discuss some of the main issues and benefits in simulatio...
