Mike: Nearly every analog instrument uses the 4-20 mA loop. Field transmitters, positioners, and variable frequency drives ...

Electrical impedance tomography (EIT) is one of the typical ill-posed inverse problems, where serious ill-posedness and the linear approximation of the forward operator lead to obvious distortions and ...

Renewable energy sources make extensive use of voltage source converters (VSC) for power transfer, and impedance-based schemes provide technical support for their stability analysis. However, due to ...
