Suppression of Base Excitation of Rotors on Magnetic Bearings
International Journal of Rotating Machinery, 2007 This paper deals with rotor systems that suffer harmonic base excitation when supported on magnetic bearings. Magnetic bearings using conventional control techniques perform poorly in such situations mainly due to their highly nonlinear characteristics ...

Measuring the role of surface chemistry in silicon microphotonics [PDF]
, 2005 Utilizing a high quality factor (Q~1.5×10^6) optical microresonator to provide sensitivity down to a fractional surface optical loss of alphas[prime]~10^–7, we show that the optical loss within Si microphotonic components can be dramatically altered by ...
