Machine learning-based software sensors for machine state monitoring - The role of SMOTE-based data augmentation

open access: yesResults in Engineering, 2022
A method for flexible vibration sensor-based retrofitting of CNC machines is proposed. As different states leave different fingerprints in the power spectrum plane, the states of the machine can be distinguished based on the features extracted from the ...

Monitoring the metropolitanization process [PDF]

open access: yesDemography, 1988
Abstract Alternative approaches have led to different interpretations of the metropolitanization process in the United States. We identify and illustrate several methods and procedures for monitoring metropolitan-nonmetropolitan population change using the 1950–1980 U.S. decennial censuses.
