The harmonic response caused by unbalanced excitation vibration for the high-speed rotating machinery will reduce control accuracy and stability of maglev motor, limit increase its speed. When active magnetic bearing is used to solve vibration, it additional electromagnetic force energy consumption, sometimes leading saturation power amplifier, transfer foundation, causing foundation vibrate. I...

Abstract. One of the major problems in using wind energy is that wind-generated electricity is more unstable than electricity generated by other sources, and therefore integrating wind energy use with traditional power generation systems can be a challenge. This problem can be effectively reduced by having accurate information about the mean and wind speed volatilities. Therefore, in this paper...

Speed ensemble of bistable (combustion) fronts in mean zero stationary Gaussian shear flows inside two and three dimensional channels is studied with a min-max variational principle. In the small root mean square regime of shear flows, a new class of multi-scale test functions are found to yield speed asymptotics. The quadratic speed enhancement law holds with probability arbitrarily close to o...
