Acceleration error coefficient

It was assumed that the motion of the fictitious particle within the above time steps is rectilinear. This simplification, which accelerates the computer calculation of the trajectories of the fictitious particle, has been show n to be justified (9). The Philips slip correction factor for an accommodation coefficient of unity (Eq. [4]) was used in the calculation of the diffusion coefficients of particles. The values of the dimensionless coagulation coefficients % obtained by the computer simulation for different particle sizes, are given in Table I. The statistical errors of the Monte Carlo simulation were estimated by the standard 3 a method (corresponding to a probability of 0.997) (13). The number of particle pairs that must be generated in order to lower the error to a reasonable level depends both on the initial distance of separation between... 

Remember that expresses the resistance of droplets of the 2th fraction to the air flow, Ai accounts for their concentration n , and j3 for the speed of their vertical gravitational fall according to (3.36) and (3.88). The velocity profiles have basically the same shape in the case of heavy droplets that fall down with acceleration and governed so by coefficients (3.81). There is no big error if these variable coefficients would be substituted by their means. 

Where a, and are regression coefficients, is the spectral acceleration at rock level and 6 is the error term. The values of the regression coefBcients a, and will vary for different site classes and for different time periods. These values were derived based on the statistical simulation of ground motions. For NEHRP site classes Ato D, ten random samples of soil profiles... 

Laurent, et al. examine ten biomacromolecules and colloidal silica in 1.7 MDa hyaluronic acid(5). For all probe particles, s had a stretched-exponential dependence on matrix c, with v = 0.5. 5 was independent of the centrifugal acceleration, i.e., experiments were in a linear domain in which solution viscoelastic properties were not evident. Contrast is to be made with the electrophoretic mobility, as discussed in the next chapter, in which one can enter a nonlinear domain in which particle mobility depends on the applied field E. The constant B was found, to good accuracy, to be linear in the particle radius, except for the very largest spheres. Laurent, et al. also measured the diffusion coefficients D of four smaller probes in the same polymer solutions. Within experimental error, s/D was independent of matrix concentration.
