Comprehensive Separation Algorithm for Single-Channel Signals Based on Symplectic Geometry Mode Decomposition [PDF]

open access: yesSensors
This paper aims to explore the difficulty of obtaining source signals from complex mixed signals and the issue that the FastICA algorithm cannot directly decompose the received single-channel mixed signals and distort the signal separation in low signal ...

Analysis and Experimental Study on Water Vapor Partial Pressure in the Membrane Distillation Process [PDF]

open access: yesMembranes, 2022
In membrane distillation, the vapor pressure difference is the driving force of mass transfer. The vapor pressure is generally assumed by the saturation pressure and calculated by the Antoine equation.

Impact Features Extracting Method for a Reciprocating Compressor Based on the ABC-SGMD Model

open access: yesApplied Sciences
In the typical vibration signal of a reciprocating air compressor, multi-source nonlinear characteristics are exhibited and are often drowned out in background noise, which leads to a lack of robustness in traditional feature analysis methods and ...
