An analysis of frequency of continuous blood pressure variation and haemodynamic responses during haemodialysis [PDF]

, 2021
Background: Higher beat-to-beat blood pressure (BP) variation during haemodialysis (HD) has been shown to be associated with elevated cardiac damage markers and white matter ischaemic changes in the brain suggesting relevance to end-organ perfusion.

Frequency Response Analysis of Buck-Boost Inverter

Mìkrosistemi, Elektronìka ta Akustika, 2019
The paper deals with processes analysis in inverter circuits. These processes are described by differential equations with periodical coefficients. Since control signals and voltages operating in an inverter circuit are independent theirs frequencies are

Improving the Convergence of Vector Fitting for Equivalent Circuit Extraction From Noisy Frequency Responses [PDF]

, 2006
The vector fitting (VF) algorithm has become a common tool in electromagnetic compatibility and signal integrity studies. This algorithm allows the derivation of a rational approximation to the transfer matrix of a given linear structure starting from ...

Frequency-Invariant Representation of Interaural Time Differences in Mammals [PDF]

, 2011
Interaural time differences (ITDs) are the major cue for localizing low-frequency sounds. The activity of neuronal populations in the brainstem encodes ITDs with an exquisite temporal acuity of about .

Steady-state visual evoked potentials can be explained by temporal superposition of transient event-related responses [PDF]

, 2011
<p><b>Background:</b> One common criterion for classifying electrophysiological brain responses is based on the distinction between transient (i.e. event-related potentials, ERPs) and steady-state responses (SSRs).

Adaptive Performance Tuning for Voltage-Sourced Converters with Frequency Responses

Applied Sciences, 2020
Renewable generation brings both new energies and significant challenges to the evolving power system. To cope with the loss of inertia caused by inertialess power electronic interfaces (PEIs), the concept of the virtual synchronous generator (VSG) has ...
