The instrumentation consisted of direct local fluid force measurement at two locations on the cylinder as well as accelerometers spaced along the cylinder axis.
Results show that the global stiffness of the beam specimen as well as external hammer excitation forces can be successfully and accurately identified from displacement measurement at two points using one camera.
Measurement at two time periods allows for the investigation of changes in residential levels, which likely reflect patterns of use.
The intensity of the remaining green fluorescence of C545T can be tuned and used for ratiometric measurement at two wavelengths.
The amount of dye is proportional to the number of metabolic active cells and can be quantified photometrically by differential measurement at two wavelengths.
The high correlation between the effects of treatment on hip bone mineral density and spine bone mineral density (r=0.90) confirms previous findings 19 that there is minimal gain from taking measurement at two sites rather than one.
