This article reviews recent progress in the use of silicon nitride and Hydex as non-silicon-based CMOS-compatible platforms for nonlinear optics. New capabilities such as on-chip optical frequency ...

Examples Frequent-flier miles are one example of a non-linear change. American Airlines introduced them as a new concept in the 1980s and gained an advantage over its competitors.

We propose a global smoothing method based on polynomial splines for the estimation of functional coefficient regression models for non-linear time series. Consistency and rate of convergence results ...

Unlike nonlinear marketing, which can be highly interactive, linear marketing takes place regardless of how consumers respond. Consumers also generally do not seek out linear marketing.

For example, Linear Variable Filters (LVF) for use in laboratory analysis systems. Thanks to a special coating technology, these filters have a precisely defined spectral response.

This paper develops an asymptotic theory for estimated change-points in linear and nonlinear time series models. Based on a measurable objective function, it is shown that the estimated change-point ...
