Body-composition changes with diet and exercise in obese women: a comparison of estimates from clinical methods and a 4-component model
weight loss body composition exercise
2016/5/31
Most methods available to clinicians for estimating
body-composition changes have been validated against estimates
from densitometry, based on a 2-component (fat mass and
fat-free mass) model.
Blind Deconvolution of Ultrasound Sequences Using Nonparametric Local Polynomial Estimates of the Pulse
Blind deconvolution pulse estimation ultrasound
2010/1/6
The problem of reconstructing the reflectivity of a
biological tissue is examined by means of blind deconvolution of
the echo ultrasound signals. It is shown that the quality of the
reconstruction ...
