摘要： An active noise control (ANC) system is disclosed for attenuating engine generated noise that contains at least one sinusoidal noise component having an amplitude and frequency that vary with changes in engine rotational speed. The ANC system includes a means for generating an input signal that contains one or more sinusoidal signal components, where each signal component has a frequency corresponding to that of a respective one of the noise components. The input signal is filtered with an adaptive filter having adjustable filtering characteristics to produce a filter output signal. Noise canceling waves are generated by a noise canceling actuator in response to the filter output signal, and the canceling waves are superimposed with the undesirable noise generated by the engine. The level of residual noise resulting from this superposition is sensed and a corresponding error signal is developed. The filtering characteristics of the adaptive filter are adaptively adjusted in accordance with the error signal and sensed indications for the engine rotational speed and acceleration. In the preferred embodiment, the characteristics of the adaptive filter are adjusted according to an algorithm having a convergence factor and a leakage factor, where the value of the convergence factor is scaled as a function of engine acceleration and the value of the leakage factor is scaled as a function of engine speed and acceleration.

摘要： A method, system and computer program product are provided for implementing automatic access control list validation using automatic categorization of unstructured text. Automatic categorization of unstructured text is performed on a plurality of documents of an access control list for determining an average term vector. Each of the documents is scored against the average term vector to identify a dissimilar document, flagged as a possible security risk. Automatic categorization of unstructured text is performed on user information of a plurality of members of a candidate access control list for determining a typical term vector. A similarity score is determined by user information and the typical term vector, members of an access control list that are dissimilar from other members of the access control list are identified.

摘要： An interface panel structure used in an electric machine; comprises a fixed seat with a fixed seat with a holding element and sliding rails and a movable sliding seat installed therein. Fixing holes for accepting the holding element and sliding grooves operated in cooperation with the sliding rails are disposed in the sliding seat. In addition, a guide rod is installed in the sliding seat for touching off the holding the holding element to separate it from the fixing hole. When the holding element and the fixing hole are engaged, the sliding seat with interface outlets disposed at the front face thereof is hidden in the fixed seat fixed in the electric machine. And, there is no need to open holes on the surface of the electric machine by means of the interface panel structure.
