Probabilistic distribution functions such as the Pareto power law and exponential functions are more appropriate than the traditional functions in interpreting these extreme/rare events.
is the one component shear rate (the absolute value brackets are used because viscosity is positive definite), and n is the power law constant.
The most common type of Non-Newtonian power law behavior is shear thickening fluid (n > 1), where the viscosity appears to increase when the shear rate increases [14].
The noise model that presented the higher values of the log likelihood is a combination between power law and white noise which best describes the noise characteristics of all three components.
Under power law distributions, most members of a population occupy the long, low part of the curve at the right (i.

showed that the power law (1) observed in large-sized variables is derived from Gibrat's law [32, 33] under inverse symmetry [24, 25].
Chung and Chi [1] proposed a sigmoid FGM, which is composed of two power law functions to define a new volume fraction and indicated that the use of a sigmoid FGM can significantly reduce the stress intensity factors of a cracked body.
The exponent in this case has a value of 1/7 but it is observed that, the value of exponent varies with the type of terrain therefore; the one-seventh power law is not suitable for wind speed extrapolation and energy estimation.
Thus, empirical power law models that give an inverse relationship between solder joint life and board thickness (raised to a power that varies from one source to another) can be misleading, if generalized.
The math describing such relationships, known as a power law, incorporates an exponent (power) to relate the change in one factor (predator biomass) to another (prey biomass).
