F.R. Larson and J. Miller proposed that creep rate could adequately be described by the Arrhenius type equation: r = A ⋅ e − Δ H / ( R ⋅ T ) {\displaystyle r=A\cdot e^{-\Delta H/(R\cdot T)}} Where r is the creep process rate, A is a constant, R is the universal gas constant , T is the absolute temperature , and Δ H {\displaystyle \Delta ...
The Hollomon–Jaffe parameter (HP), also generally known as the Larson–Miller parameter, [1] describes the effect of a heat treatment at a temperature for a certain time. [2] This parameter is especially used to describe the tempering of steels, so that it is also called tempering parameter.
In optics, Miller's rule is an empirical rule which gives an estimate of the order of magnitude of the nonlinear coefficient. [1]More formally, it states that the coefficient of the second order electric susceptibility response is proportional to the product of the first-order susceptibilities at the three frequencies which is dependent upon.

In the equation shown on this page, it shows the larson-miller parameter to be the activation energy over the gas constant and then has log of the time on the other side. Up until this point natural log was being used, in that case it should be the natural log of time.
In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.The general form of its probability density function is [2] [3] = ().
The solution of the corresponding constitutive equation leads to a relaxation function of the Mittag-Leffler type. It is defined by the power series with negative arguments. This function represents all essential properties of the relaxation process under the influence of an arbitrary and continuous signal with a jump at the origin. [7] [8]
The Miller capacitance can be mitigated by employing neutralisation. This can be achieved by feeding back an additional signal that is in phase opposition to that which is present at the stage output. By feeding back such a signal via a suitable capacitor, the Miller effect can, at least in theory, be eliminated entirely.
The LLG equation describes the rotation of the magnetization in response to the effective field H eff and accounts for not only a real magnetic field but also internal magnetic interactions such as exchange and anisotropy. An earlier, but equivalent, equation (the Landau–Lifshitz equation) was introduced by Landau & Lifshitz (1935): [1]
