Aortic input impedance in cardiovascular disease
Progress in Cardiovascular Diseases, 1982 0 VER the past 2 decades considerable interest has centered around attempts to define and quantify hemodynamic consequences of cardiovascular disorders. In general, these attempts employed traditional hemodynamic measurements, like aortic and ventricular pressures, cardiac output, peripheral resistance, ventricular volumes, ejection fraction, etc., to ...

Impedance-Based Modeling and Common Bus Stability Enhancement Control Algorithm in DC Microgrid
IEEE Access, 2020 In this paper, impedance modeling of a DC microgrid system consisting of a source and load converter, including an input filter, is performed. Impedance-based modeling has been used to derive mathematical models of the output impedance of the source ...

Trombone Transfer Functions: Comparison Between Frequency-Swept Sine Wave and Human Performer Input
Archives of Acoustics, 2013 Source/filter models have frequently been used to model sound production of the vocal apparatus and musical instruments. Beginning in 1968, in an effort to measure the transfer function (i.e., transmission response or filter characteristic) of a ...

Virtual Impedance Shaping for the Bus Conversion System in the Hybrid AC/DC Grid
IEEE Open Journal of Power ElectronicsThe bus conversion system in the hybrid AC/DC grid is usually composed of a three-phase interlinking converter and a DC-side input filter. The impedance interaction between the converter and the input filter may cause instability of the DC-link ...
