A phoneme is a unit of sound in speech. A phoneme doesn't have any inherent meaning by itself, but when you put phonemes together, they can make words. Think of when adults try to get a baby to say his or her first word.
Bioelectrical Impedance Analysis or Bioimpedance Analysis (BIA) is a diagnostic tool that accurately assesses your complete body composition - the measurement of body fat in relation to lean body mass as well as cell membrane integrity, intra and extracellular water, and other specific aspects of body composition.IA also provides a measurement of fluid and body mass that can be a critical assessment tool for your current state of health. BIA also serves to measure your progress as you work to improve your health.
Arterial stiffness can be measured noninvasively by the. use of the PPG technique, which reflects the changes in. blood volume with each heart beat. Perhaps the most. exciting application of PPG waveform analysis is the. possibility of providing a rapid biophysical measure of. diseases or aging process [10]. PPG provides an estimation. of coetaneous blood flow by measuring the dynamic. attenuation of infrared light by the blood volume present in. tissue [11]. Analysis of the PPGâs contour in terms of crest. time revealed age dependence and clinically significant. variations between health and disease, including.
