A COMPARISON OF PHYSICAL SOIL ORGANIC MATTER FRACTIONATION METHODS FOR AMENDED SOILS

Selecting a suitable physical fractionation method, to investigate soil organic matter dynamics, from the plethora that are available is a difficult task.Using five different physical fractionation methods, on soils either nontreated or with a history of amendment with a range of exogenous organic matter inputs (Irish moss peat; composted horse man

An effective bearing fault diagnosis model based on machine learning is proposed in this study.The model can separate into three stages: feature extraction, feature selection, and classification.In the stage of feature extraction, multiresolution analysis (MRA) and fast Fourier transform (FFT) are applied to Compressor Electrical Cover extract the
