Ultrasonic velocity measurements through the calcaneus: Which velocity should be measured?
Osteoporosis International, 1993The assessment of skeletal integrity by the measurement of ultrasonic velocity through the calcaneus has only recently become widely available and is usually made in conjunction with the measurement of broadband ultrasonic attenuation. Using data obtained with a contact ultrasonic bone analyser (CUBA) system, this report examines whether ultrasonic ...

Whether the Greenland and Antarctic ice sheets are shrinking, growing or in equilibrium has become the subject of current scientific investigations because such changes would be of worldwide importance. For instance, melting of the two ice sheets would cause a rise in sea level of as much as 70 m (R H Thomas et al 1985 NASA Tech. Memo.

We argue that Roberts’s argument for the thesis that absolute velocity is not measurable in a Newtonian world is unsound, because it depends on an analysis of measurement that is not extensionally ...

Yarn velocities in the false twist texturing process are a function of time and position within the process. The ability to measure the yarn velocity at discrete positions along the process would be a major step forward for those investigating the process characteristics.

Differential doppler velocity measurements
IEEE Journal of Quantum Electronics, 1969Observed signal characteristics and measurement accuracy are described for a recently developed noncontacting optical velocity sensing method as applied to extended moving surfaces. This method is based on an optical heterodyne measurement of the difference between two Doppler shifts which are produced in the light scattered through two different ...

A method for measuring the modu lus of elasticity of fibers and films by sonic means is described, and the results of an exploratory study of this modulus in various nat ural and synthetic fib ers and films are given. The method is based on the equation for the prop agation of longitudinal (sound) waves in elastic materials, which expresses the ...

Velocity Measurements in Metallic Melts
Volume 1: Symposia, Parts A and B, 2005Various developments of velocity measuring techniques, their tests in different liquid metals, and applications in hot melts are reported. A Mechano-Optical Probe (MOP) performing local measurements up to temperatures of about 700°C has been developed and successfully tested.

The Measurement of Projectile Velocities
Transactions of the American Institute of Electrical Engineers, 1920The paper discusses the requirements imposed by proving ground practise upon a chronograph which is intended for general ammunition testing. Instruments of the standard pre-wvar pattern were entirely inadequate in number for testing the immense quantities of ammunition contracted for by the Government during the war.

Rheometry using velocity measurements
Rheologica Acta, 2008Traditional methods of rheometry employ simple flows such as viscometric flows and measure stress or volumetric flow rate to determine the rheological parameters in the constitutive equation. One can find analytic solutions for stress and volumetric flow rates for these simple flows, and comparison of them with experimental data determines rheological ...

Grain-Stream Velocity Measurements
Transactions of the ASAE, 1971P grain damage is a common problem in the grain industry. The technological changes in grain production and harvesting, especially the recent shift to field shelling of corn, have added to this problem. Either field-shelled or artificially dried corn is often brittle and easily broken. With the repeated handling common in commercial marketing channels,
