Onlinepaymentshaveimprovedthe velocity oftrade. Examplesofvelocityvelocity The hunter selects avelocityuniformly at random between 0 and 1 and proceeds in a clockwise direction according to thisvelocity. From theCambridge English Corpus The remaining generalised velocities must be formulated as functions of the previous ones. From theCambridge English Corpus The unknowns (both velocities and stresses) are assumed to vary linearly over each element. From theCambridge English Corpus It is commonly supposed that any explicit numerical method with fixed time-step is destabilized by a sufficiently largevelocityof any particular atom. From theCambridge English Corpus Then the water composition approximately oscillates at each point of the aquifer in phase with the watervelocity. From theCambridge English Corpus Mean shear increases the separation between particle pairs (see figure 4), thereby helping t o decorrelate their random velocities. From theCambridge English Corpus Respiratory excursions substantially modify thevelocityprofile and should be avoided during standard recording. From theCambridge English Corpus The stereoscopic relations which convert the images of the bead trajectories to the three-dimensionalvelocityfield are given in the appendix. From theCambridge English Corpus We further presume that the required characteristics of the mean flow (meanvelocity) and turbulence (intensity, scale size, etc.) may be specified. From theCambridge English Corpus The evolution of the turbulentvelocityfield in these air data is far more coherent than were such measurements in water. From theCambridge English Corpus The constraint a2+p2= 1 ensures that the variance of the turbulentvelocityis correct. From theCambridge English Corpus Unlike the point source cases, there was no indication of singularities in thevelocityfield. From theCambridge English Corpus There was also a reduction in the vertical phasevelocityof the instabilities. From theCambridge English Corpus The usual technique for analysing the problem defined above starts with the derivation of a single equation for the verticalvelocitycomponent. From theCambridge English Corpus The verticalvelocityin the right vortex is spatially distributed as in the left vortex.

From theCambridge English Corpus conduction velocity The average linear conduction velocity of delayed calcium responses was 10.7 + 0.82 m sec-1 (n=75). From theCambridge English Corpus constant velocity This region is moving downstream with aconstantvelocity.
