The Taguchi method of experimental design was employed in this study to scrutinize the impact welding processing factors, including rotating speed, travelling and pin profile on ultimate tensile strength, microhardness, strength Friction Stir Welded AA 8052 joint. S/N values for each process specification were calculated using an orthogonal array L9 design. 1150 rpm 28.5 mm/min greatest evaluat...

abstract icssdom is a mathematical synthetic model that was written with fortran77 and in which used sa simulation annealing algorithm like an internal loop in basic structure of icss hydrodynamic simulation model. this model presented by mohseni movahed in 1381. this model is able assess current performance and present optimal operation considering downstream requirement of turnout in real con...

Abstract Aiming at formulating reasonable curing process parameters of powder coating, solving the problems over-drying thin plate and impervious drying thick during combined workpieces with different thicknesses, analyzing optimal temperature range coating by differential scanning calorimetry (DSC), designing a three-factor four-level DOE test scheme within to time are necessary. Using Minitab...

the paper describes an investigation about the application of the new multiple-impedance discontinuities model for optimizing profile diffuser barriers. the new multiple-impedance discontinuities model is much faster than the numerical method, thus it is used in an optimization process. the a-weighted insertion loss was used for the traffic noise spectrum. the result of optimization, which is d...
