An Adaptive Variational Mode Decomposition Technique with Differential Evolution Algorithm and Its Application Analysis

open access: yesShock and Vibration, 2021
Variational mode decomposition is an adaptive nonrecursive signal decomposition and time-frequency distribution estimation method. The improper selection of the decomposition number will cause under decomposition or over decomposition, and the improper ...

A Comprehensive Mixed-Mode Time-Domain Load- and Source-Pull Measurement System [PDF]

open access: yes, 2010
We present a novel test set devised for nonlinear balanced device characterization using load-pull techniques. The system is capable of measuring the voltage and current waveforms at the calibration reference planes while independently tuning the device ...

Differential mode: manifestation in toponymics

open access: yesНеофилология, 2020
We consider toponyms that are related to the same appellative or ascend to the same anthroponym or to the same family anthropolexem. We prove that this kind of nomination of toponyms contradicts its main purpose – to name single objects and creates ...
