Near Infrared Oxymetry

Near-infrared spectroscopy (NIRS) and near-infrared optical imaging (NIRI) on turbid media such as biological tissue is a rapid growing field of interest. The techniques offer the ability to use light to non-invasive quantify metabolite concentration and to image structure within the human body. In particular methods for monitoring the blood volume are currently under study. Near infrared light (+/- 700-900 nm) is used in the applications because of the relative transparency of tissue to light in this wavelength region while the oxygen dependent absorption of hemoglobin is still observable.

Order of frictions and stiffnesses…

For lumped systems consisting of different frictions and stiffnesses, there has been confusion in literature about hysteresis curves and virtual play for many decades.
