Abstract: Embodiments of the present disclosure relate to a new approach used for adaptively selecting an acoustic feature extractor used in an Artificial Intelligence system. The method comprises: acquiring a frame of acoustic signal; checking a status of a flag to be used to indicate a proper acoustic feature extractor to be selected, the first status of the flag indicates a low-cost feature extractor associated with quasi-stationary acoustic signal, the second status of the flag indicates a high-cost feature extractor associated with non-stationary acoustic signal; processing the frame of acoustic signal by the selected acoustic feature extractor indicated by the checked status; determining, based on data generated in the processing of the frame of acoustic signal, an actual status of the frame of acoustic signal; and updating the status of the flag according to the actual status.

Abstract: A method of pre-placing a reaction material onto a surface of a metal workpiece substrate involves the use of oscillating wire arc welding. The method involves depositing and adhering the reaction material from a consumable electrode rod. In doing so, the reaction material can be deposited at any time before the metal workpiece substrate is ready for joining by reaction metallurgical joining, and the size and shape of the reaction material deposit can be more easily controlled.
