Root mean square average

The above-mentioned quantity (r2)1,/2 is closely related to the so-called radius of gyration RG, which is the root-mean-square average of the distances of the molecular segments from the... 

Any linear polymer molecule, even a reasonably stiff rod, will coil randomly, provided the chain is sufficiently long. In addition to the size of the monomer units, the tendency for coiling is affected by the forces between the units as well as the interaction between the polymer and the solvent. One measure of the stiffness of a polymer molecule is the end-to-end distance (R). For a polydisperse polymer the root-mean-square average of R (R2)v2 is used. R is affected by the properties of the polymer itself as well as by the interaction of the solvent. The better the solvent the more the polymer... 

This statement refers to the root-mean-square average, which is the square root of the arithmetic average of the values of the square of the speed. 

In this expression, y is the gyromagnetic ratio and is the root-mean-square average of the X component of the fluctuating local field. Note that wo replaces o) in the expression for the relaxation time, which, under the extreme-narrowing condition, becomes 27 [b2l] Tc-Thus, the relaxation time T decreases as Tc increases (i.e., as mobility decreases with, for example, larger molecules or lower temperatures). This regime is depicted for Tj at the left of Figure A5-2 note that Ti is independent of the resonance fi equency coq here. 

In multicomponent systems, such as one- or more-dimensional lattices, successive transfer processes are coherent. The exciton migrates straight forward with constant group velocity, that is, with the r.m.s. (root-mean-square)-average distance from the original site of the excitation in proportion to time. 

Once the moment tensor has been computed, a number of source parameters can be calculated to aid interpretation. The most basic of the source parameters is the scalar seismic moment Mo which is a measure of the irreversible inelastic deformation in the area of the rupture and is the root-mean-squared average of the moment tensor elements ... 

Profilograph (profilometer) n. An instrument that measures the roughness of a surface, usually expressed as the local root-mean-square average in nm (or pm). The profile taken in any direction can be magnified and displayed graphically. Reason RE (1970) The measurement of surface texture, modern workshop technology, Part 2. The Macmillan Co., New York. 

In Eq. (78), 6p denotes the root mean square average of the distribution obtained from the second derivative of Q(n) for n p... 

Turbulent flow is characterized by the presence of eddies, which means that the local flow velocity u generally differs from the time-average value u. The velocity fluctuates in a chaotic way and the average difference between u and equals zero. However, the root-mean-square average...
