The power performances we present in this work are

w x comparable to those obtained in the literature 6 at relatively similar frequencies for smaller devices. Even with larger dimensions, our four-emitter finger AlGaAsrGaAs HBT is designed to improve the thermal behavior, and exhibits an output power of 1 W at 1.8 GHz with a high linearity. This can be an advantage in terms of easier fabrication technology and better reliability.

Subsonic #ows over Helmholtz resonators often cause strong periodic pressure #uctuations inside the resonators over a range of outer #ow velocities. The #ow-excitation mechanism is known to be governed by both the shedding of discrete vortices within the shear layer over the ori"ce and the acoustic

In this work, we address the in#uence of period variation on the Westland CH-46E helicopter vibration data. The estimation of the time-varying shaft speed by using a newly developed constrained AR(2) estimator and the well-known EKF estimator will be discussed. The in#uence that the period variation
