In signal processing, system theory, and in information theory signals are either complex valued waveforms or sequences of dimensionless complex numbers.
When analyses were questionable (e.g. large variation in AI values among waveforms), the waveforms were re-analyzed by another technician.
The LV d P/d tmax was predicted on the basis of impedance values and waveform characteristics and this was compared with the LV d P/d tmax measured invasively.
Spontaneous variations in CBFV and arterial blood pressure were measured over a 60-minute period, digitized and then processed calculating the time-averaged values using waveform time integration for 6-s intervals.
Pulsatility index (PI) is equal to systolic (S) minus diastolic (D) amplitude value of arterial waveform, divided by the mean (M) value of the area under the waveform.
In the study, we evaluated the relationship between changes in intrahepatic blood flow and portal pressure (PP) measured intraoperatively in patients with portal hypertension (PHT), aiming to discuss the indicative value of HV waveform and its quantitative index DI firstly, then the cause of changes in HV waveforms both from the histological and hemodynamic angles.
And the binary value of Figure8 waveform data is "101", through the above three kinds of mode similarity measure it can make effective recognition for the mud pulse signal.
(4) In the tensile fracture zone, the precursor information of acoustic emission in the fracturing process of roof includes acoustic emission count more than 1000, AE cumulative counts appear to spurt and the absolute value of the waveform signal intensity of acoustic emission is greater than 0.4 mv.
In the tensile fracture zone, the precursor information of acoustic emission in the fracturing process of roof includes acoustic emission count more than 10,000, AE cumulative counts appear to spurt and the absolute value of the waveform signal intensity of acoustic emission is greater than 4 mV. .
The effect of the circuit is to shift the DC value of the waveform.
