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 ...

Journal of Physics E: Scientific Instruments, 1983
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 ...

Textile Research, 1944
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,

Photomicroscopic Sublayer Velocity Measurement
Journal of the Hydraulics Division, 1970The measurement of velocity in the boundary layer region can be a difficult problem using probes. The use of a microscope to observe the motion of small tracer particles can yield quantitative velocity data without disturbing the flow. The application of this technique to turbulent open channel flow is described.
