Abstract: PURPOSE: A method is provided to reduce eddy current losses and achieve improved characteristics even in the high frequency. CONSTITUTION: A method comprises a step of designing an alloy by reflecting magnetic and mechanical properties; a step of forming Fe-Al based and Fe-Co based alloy ingots by using a vacuum induction melting system or a vacuum arc melting system; a step of grinding the alloy ingots into lamellar powder; a step of mixing a polymer binder and the lamellar powder; and a step of compacting and hardening the mixture.

Abstract: PURPOSE: A sound source classification device and a method thereof are provided to accelerate computing speed by classifying sound sources based on the characteristic parameters and information about reference sound source. CONSTITUTION: A sound source detection unit(110) detects a segment in which a sound source generates. A sound source characteristic extraction unit(120) extracts characteristic parameters of the sound source. A reference sound source storage(140) stores the information about at least one reference sound source. A sound source classification unit(130) classifies the sound signals based on the characteristic parameters and the information about the reference sound source. The sound source characteristic extraction unit extracts the characteristic parameters using MFCC(Mel-Frequency Cepstral Coefficients) method.
