Using the Hanggi ansatz to truncate the evolution equation for probability density, an approximate Fokker–Planck equation (AFPE) is derived. This AFPE is valid for one-dimensional general systems driven by two multiplicative colored noises (τ1≠0 and τ2≠0) that are correlated in color...

Stochastic resonance (SR) induced by the signal modulation is investigated, by introducing the signal-modulated gain into a single-mode laser system. Using the linear approximation method, we detailedly calculate the signal-to-noise ratio (SNR) of a gain-noise model of the single-mode laser,...

Owing to the considerable virtues of semiconductor lasers for applications, they have become the main optical source for fiber communication systems recently. The behavior of stochastic resonance (SR) in direct-modulated semiconductor laser systems is investigated in this article. Considering...

The stochastic resonance phenomenon is studied in a single-mode laser system driven by correlated multiplicative and additive colored noises without modulation by external periodic force. We detect that there are multiple extrema (maximum) in the curve of the mean output laser intensity versus...

Due to the rapid development of the automobile industry and the ever-increasing quantities of produced and sold automobiles in China, many problems such as fuel scarcity and air pollution have emerged. To alleviate such problems, one solution is to promote households to purchase...

To infer on functional dependence of regression parameters, a new, factor based bootstrap approach is introduced, that is robust under various forms of heteroskedastic error terms. Modeling the functional coefficient parametrically, the bootstrap approximation of an F-statistic is shown to hold...

What does the saving-investment (SI) relation really measure and how should the SI relation be measured? These are two of the most discussed issues triggered by the so-called Feldstein-Horioka puzzle. Based on panel data we introduce a new variant of functional coefficient models that allows to...

In performance evaluations, data without explicit inputs (such as index data, pure output data) are widely used. To directly use such data, this paper presents a study on building DEA models without explicit inputs, so-called DEA-WEI models, which are applicable to the evaluation applications...
