This phenomenon can be described by the laws of probability and the methods of statistics; from probability distributions it is possible to determine averages or mean values for such parameters as velocity, pressure, etc. These mean values can then be related to the macroscopically measurable ...

Velocity=dXdt=X=−ωX0sin(ωt)Acceleration=d2Xdt2=X=−ω2X0cos(ωt) Inserting the above expression for acceleration, or d2X/dt2, into the equation for Fs yields the following: Mgcd2Xdt2+KX=0−Mgcω2X0cos(ωt)+KX=0−Mgcω2X+KX=−Mgcω2+K=0 Solving this expression for ω...
General expressions for mass dispersion and mass resolution, taking into account the dominant first-order or second-order aberrations, are developed from the exact cycloidal solutions for arbitrary source and image distance from the field boundaries, as well as for arbitrary lengths of motion within ...
At a slope angle of 45°, as the median particle size increased, energy loss around the slope toe decreased, the efficiency of momentum transfer increased, and the distance of the velocity maintenance stage increased. We presented an improved average velocity formula for granular flow and a ...
The distance of the sprayer nozzle was 50 mm from the sample, and a spray pressure of 10 psi with a spray nozzle motion velocity of 1,200 mm min−1 was used. Four passes were used to apply the MALDI matrix. Image-guided SCMS analysis The brightfield and fluorescence ...
