...CEline weight rating for fly rods was found to be a function of the stiffness and frequency of the rods. For the first time, an empirical method for the selection of a line weight that matches the performance characteristics of a rod is presented. Keywords: Fly rods, fly lines, vibration, large...

... Abstract Vibration generated by underground railways is difficult to control because of the very limited space available in a tunnel. A popular approach is to use ‘floating slab track’ whereby the rails are fixed to a large concrete foundation separated from the tunnel wall by a resilient...

...-induced swing of ropeway carriers has attracted many researchers. It had been said that it was impossible to reduce the vibration of pendulum type structures such as ropeway carriers by a dynamic absorber. But in 1993, Matsuhisa showed that the swing of carrier can be reduced by a dynamic absorber...
