This paper proposes an active noise control algorithm for periodic disturbances of unknown frequency. The algorithm is appropriate for the feedback case in which a single error microphone is used. A previously-proposed algorithm for the rejection of sinu-soidal noise sources is extended for the cancellation of multiple harmonics. Unlike many other(More)
The present paper reviews the results obtained with different modalities of treatment employed in isolated fractures of the zygomatic complex. Seventy-three patients were re-examined with respect to infraorbital nerve function. The results obtained suggest that the incidence of hypoaesthesia of the infraorbital nerve following fracture of the zygomatic(More)
