Studies On The Behaviour Of Solid Particles In Turbulent Gas Flows
… was based upon a vortex method in which the velocity fluctuations of the turbulent flow were simulated by arrays of randomly positioned vortices. The calculation of the motion of the spherical particles was based upon the forces acting upon a particle as a function of the local fluid …

Laser plasma particle velocities
… trace pictures of the probe signal, four velocity 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 …

Structure of turbulence in the marine atmospheric surface layer
… m above the water surface, where the mean wind velocity was 6.74 m/s. This burst period corresponds well with the peaks obtained from the autocorrelation of the streamwise velocity signal and the first moment of the stress spectrum, confirming the quasi-periodic nature of this phenomena. …

Development of a Standardized Method for Actuator Characterization using Active Control of Impedance
… Using data from the sensing apparatus (force and velocity signals), the active control system will drive the second actuator to recreate any load condition the first actuator would be supposed to experience in a real application. <i>[Vita removed May 14, 2012. Gmc]</i>

Functional analysis of middle temporal visual area and its associated behavior
… Microstimulation can introduce an additional velocity signal into MT and the pursuit and saccadic systems usually compute a vector average of the visually evoked and microstimulation-induced velocity signals.

Patterns and drivers of seasonal land-ice-flow around Antarctica
… level. Unlike the Greenland Ice Sheet, where ice velocity signals are well resolved over both inter- and intra-annual timescales, observations of seasonal signals are limited over the grounded ice in Antarctica. Assessing the degree of seasonal ice-flow variability, and establishing a …

Does cerebellar cortex function as a forward internal model for motor control?
… state (i.e. kinematic variables like position, velocity) of the limb. Previous psychophysical, imaging, and patient case studies suggest that the cerebellum is a possible location for implementation of an internal model. However, very few electrophysiological studies have investigated whether …

The Application of Doppler LIDAR Technology for Rail Inspection and Track Geometry Assessment
… Using two pairs of lenses to capture speed signals from both rails individually, the track speed, curvature, and lateral and vertical geometry variations on each side are determined. LIDAR lenses are installed with a slight forward angle to generate velocity signals that contain two …

Characteristics of Coherent Structures in Marine Atmospheric Surface Layer
… layer. With Taylor's hypothesis, the temporal velocity signals have been transformed to spatial fluctuations and then visualize these spatial velocity fluctuations to identify the coherent structures. It has been confirmed that there exist similar coherent structures in the marine atmospheric …

Wave-induced sediment transport on an estuarine intertidal flat
… sensors; field trials of pressure and velocity sensors under estuarine and open-coast waves; and experiments to test whether optical and acoustic backscatter sensors could be used to separately measure the concentration of suspended silts and suspended sands. Comparison of pressure and …
