WebThis intensity correlation function is directly proportional to the time correlation function of the concentration; at low wavevectors it allows investigation of the diffusion constant of the solution; at higher wavevectors it probes the internal motions of polymer chains. The intensity scattered from a sample is proportional to the irradiated sample … Second- (triangles), third- (circles) and fourth-order (open circles) intensity … WebThe correlation of horizontal and vertical ground motion intensity measures (GMIMs) is an important basis for some researches such as the selection of horizontal and vertical ground motions, etc. Thusly, 975 groups of ground motions are selected from the PEER NGA-West2 database and combined horizontal GMIMs via four combination methods and vertical …
WebWhat is a Correlation Function (Correlogram)? Correlation is a statistical method for measuring the degree of non-randomness in an apparently random data set. When applied to a time dependent intensity trace, as measured with a dynamic light scattering instrument, the correlation coefficients, G (τ), are calculated as shown below, where τ is ... WebThe intensity recorded by each detector is the square of the wave amplitude, averaged over a timescale that is long compared to the wave period but short compared to the fluctuations in : where the overline indicates this time averaging.
