Laser plasma particle velocities
… signals occurred with regularity. The plasma velocities detected by the probe were determined to be 3.7 X 10(7) cm/sec, 1.5 X 10(7)CM/Sec, 5.6 X 10(6) cm/sec (the bulk of the plasma) and 4.o X 10(6) cm/sec. A fifth, very fast signal at 1,0 X 10(6)cm/sec was also detected but it was not …

Extraction of drilling-angular velocities using a nodal-spatial array of in-plane translational velocities
… technique to extract drilling-angular velocities from a nodal-spatial array of in-plane translational velocities is developed. The technique utilizes numerical methods for simulation of solutions. A finite element method using I-DEAS 4.1 is used for calculation of in-plane translational …

The Impact of Peculiar Velocities on Supernova Cosmology
… We investigate the impact of correlated peculiar velocities on the accuracy of the estimated cosmological parameters calculated using type Ia supernovae. We use mock galaxy catalogues constructed from the Millennium Simulation, the largest dark matter N-body simulation run to date. Supernovae are …

Influence of extreme velocities on dynamic cavity expansion
… cavitation fields with extreme dynamic expansion velocities have little been studied, especially in materials without a definite yield point. In this thesis, DCE in a hardening elastoplastic medium is considered under extreme velocities. Two nonlinear differential equations are used to describe …

Experimental determination of pressures and velocities in plant xylem
… were conducted to determine pressures and velocities in the conducting vessels of the xylem portion of a plant using corn syrup as the working fluid and Plexiglas tubing as the test section. The first experiment was performed using a straight duct to model the flow in a xylem vessel without …

Characterization of microparticle velocities in converging-diverging nozzle systems
… models, and simulations to characterize particle velocities. This thesis utilizes an experimental system incorporating a converging-diverging nozzle to accelerate well characterized particles to high speeds via aerodynamic drag force on the particle and measures the resulting velocities. Velocity …

Measurement of electromagnetic signal velocities in saturated fine-grained soils
… Analysis was developed for measurements of velocities in fine-grained soils. The developed measurement cell was used to undertake velocity measurements in parallel with geotechnical index tests, in order to develop cross-disciplinary relationships. It was found that relationships exist …

Precise radial velocities and simultaneous magnetic flux estimates from intensity spectra
The Radial Velocity (RV) community has made tremendous leaps forward in the past decades detecting and characterising ever smaller and lighter exoplanets. In recent years, this trend has been broken as planet-induced RV signals smaller than 1 m/s are drowned out by the stars' activity. The …
