A METHOD FOR DETERMINING INTRINSIC MODE FUNCTION NUMBER IN VARIATIONAL MODE DECOMPOSITION AND ITS APPLICATION TO BEARING VIBRATION SIGNAL PROCESSING

A Method for Determining Intrinsic Mode Function Number in Variational Mode Decomposition and Its Application to Bearing Vibration Signal Processing

Variational mode decomposition (VMD) method has been widely used in the field of signal processing with significant advantages over other decomposition methods in eliminating modal aliasing and noise robustness.The number (usually denoted by K) of intrinsic mode function (IMF) has a great influence on decomposition results.When dealing with signals

Humanitarian Handicrafts

This paper asks how craft practice can inform historical reconsiderations of handicraft produced within a Supplements humanitarian socio-economic framework (to support humanitarian aims or fund-raising initiatives), and in turn explores how historical processes become materialised in contemporary humanitarian craftwork.By considering the possibilit
