Learn how nonlinear and linear regression models differ, predict variables, and their applications in data analysis for ...

Researchers at the University of Tsukuba employ a modified mathematical technique to make complicated nonlinear equations more tractable, which can lead to more accurate control systems for mechanical ...

Nonlinear frequency conversion exploits the intrinsic interaction between intense optical fields and the polarisation response of a medium to generate new colours of light. When the electric field of ...

The nonlinear susceptibility is a measure of a material's nonlinear response to an applied electric field. It determines the strength of the nonlinear effects and is related to the crystal's symmetry ...
