The borehole transmitter of the system is the core where the four measurements frequencies (312.5, 625, 1250 and 2500 kHz) and the vital references frequency (156.25 kHz) are generated.
The results are presented based on FFT and Hilbert-Huang transform to separate and to extract human vital sign frequencies, as well as the micro-Doppler shift characteristics.
Finally, according to (32), (k_{2}) is a function of the vital rates and frequency.
In the single dose phase, AE questioning, vital signs, respiratory frequency and a 12-lead ECG were conducted at the time of drug administration and then at 1, 2, 4, 8, 12, 24, 36 and 48 h after drug.
We evaluated the MV and weaning time, maximum inspiratory pressure, maximum expiratory pressure, vital capacity, respiratory frequency to tidal volume ratio (f/Vt), use of noninvasive ventilation (NIV) post extubation, and re-intubation rate.
Secondary efficacy endpoints comprised additional pulmonary function tests including FEV1 % predicted normal, Forced Vital Capacity (FVC), frequency of asthma exacerbations, and data gathered from patients' telephone diaries including morning and evening Peak Expiratory Flow Rate (PEFR), asthma symptom scores, sleep disturbance scores, and frequency of rescue medication use.
Vital rates, relative frequencies of vital occurrences that affect changes in the size and composition of a population.
We summarized baseline characteristics and prevalence of drugs by indicating chronic condition, overall and by vital status, as frequencies and percentages or means and standard deviations.
We consider the observed frequency of vital sign instability as a minimum prevalence, since the vital signs were recorded as part of the clinical routine.
We assess the effect of Alliaria removal on Maianthemum growth and three vital rates: annual flowering frequency, retrogression of flowering plants to non-flowering the following year and the frequency of prolonged vegetative dormancy (Shefferson 2009).
