Homotopy analysis method

The HAM is an analytic approximation method designed for the computer era with the goal of "computing with functions instead of numbers."

Nicolas Minorsky

In her memorial paper to Nicolas Minorsky published in the IEEE Transactions On Automatic Control, author Irmgard Flügge-Lotz stated that Minorsky's greatest contribution to the development of nonlinear mechanics in the U.S. was Minorsky's early recognition that important papers in the field were being published in the Soviet Union in a language that few American researchers could read.

Nonlinear element

In an electric circuit, a nonlinear element or nonlinear device is an electrical element which does not have a linear relationship between current and voltage.

Organic photorefractive materials

Organic photorefractive materials are a nonlinear medium in which large amounts of information can be recorded and read.

Most nonlinear equations can be solved by using the Parker-Sochacki method, which is a slight variation of the auxiliary variable method.

Unscented transform

In 1994 Jeffrey Uhlmann noted that the EKF takes a nonlinear function and partial distribution information (in the form of a mean and covariance estimate) of the state of a system but applies an approximation to the known function rather than to the imprecisely-known probability distribution.

Variance-based sensitivity analysis

Variance-based measures of sensitivity are attractive because they measure sensitivity across the whole input space (i.e. it is a global method), they can deal with nonlinear responses, and they can measure the effect of interactions in non-additive systems.
