A Preliminary Investigation Comparing Craniofacial Metric Measurements and 3D Virtual Measurements
… 8 skulls and evaluated the standard 24 metric measurements in Delta analysis software in comparison to standard metric measurements. The scanned measurements were then compared to the standard metric measurements using the same landmarks. Of the original 48 measurements, 33 (68.75%) fail to …

Current measurements in electrospinning
Electrospinning provides an economical method of producing nanofibers. The current carried by the main spinning jet is found to be one of the factors in determining the diameter of the fiber product. However, current sources such as the corona discharge and secondary jets will lead to a systematic …

Measurements of Atmospheric Radicals
… in a significant improvement in time-resolution measurements of ambient EPFR. In the second study, concentrations of OH were measured of select PAH and oxidized-PAH in conditions designed to mimic individual cloud droplets exposed to sunlight. Significant concentrations of OH were observed, as …

Measurements of FEL dynamics
The design, implementation and commissioning of a time-resolved electron energy spectrometer system are discussed. Since its installation at the FELIX free-electron laser user facility in Nieuwegein, The Netherlands, the spectrometer system has been in regular use as a diagnostic and investigative …

Modern Rossi alpha measurements
… highly enriched uranium, HEU, Zeus experiment. Measurements are taken at several subcritical configurations, at critical in the presence of a source, and at one supercritical point. During the experiment, the List-mode module generates time tags of incoming neutron pulses. After the experiment, …

Tomographic measurements of barotropic motions
In 1983, continuous acoustic transmissions centered at 133 Hz and with a resolution of 60 ms were transmitted for five days from Oahu to the coast of Northern California (4000 km range). A maximum likelihood estimate of the change in acoustic travel time (based on phase) between received pulses is …

Surface-referenced current meter measurements
… frames. One problem with surface-following measurements is the biasing effects of the waves. A technique for making unbiased measurements is developed. This technique requires that both the sensor velocity and the fluid velocity be measured. A sensor platform, the Surface Acoustic Shear …

Time domain antenna pattern measurements
… ranges causes distortion of antenna pattern measurements: The multi path components have differing path lengths and hence can be separated by illuminating the antenna under test with short-duration pulses. Alternatively, antenna measurements can be made in the frequency domain, and the …

CEBAF Upgrade Bunch Length Measurements
… performed. Three other techniques were used for measurements and comparison purposes without modifying the old procedures. Two of them can be used when the beam is not compressed longitudinally while the other one, the synchrotron light monitor, can be used with compressed or uncompressed …

Measurements of MRI Induced Heating
The appeal of magnetic resonance imaging (MRI) stems from the fact that it can generate internal images of the human body noninvasively, with high temporal and contrast resolution, and without requiring ionizing radiation. Instead, MRI requires the use of a relatively safe radio frequency (RF) …
