Parameter Analysis of an Intershaft Dual-Rotor with the Application of Squeeze Film Dampers
The squeeze film damper is usually adopted in the rotor system to suppress the vibrating motion of the rotor system. In this work, not only are the physical parameters of the squeeze film damper analyzed but also the system parameters, like the number of

Phase-controlled nonlinear interferometry [PDF]
We have studied the influence of (relative) phases between fundamental and generated harmonic in a variety of nonlinear optical experiments. The concomitant large coherence length and the various methods of phase-control known from linear optics facilitate amplitude superposition and the generation of novel interference patterns, which may be used to ...
