Abstract Environmental perturbations and noise are source of mode mixing interferences between the propagating modes a complex multi-mode fiber. Typically, they characterized by their correlation (paraxial) length, spectral content which describes degree coupling various modes. We show that an appropriate control these quantities allows to engineer Levy-type relaxation processes initial excitat...

Levy and Levy (Management Science 2002) present data that, according to their claims, violate prospect theory. They suggest that prospect theory’s hypothesis of an S-shaped value function, concave for gains and convex for losses, is incorrect. However, all the data of Levy and Levy are perfectly consistent with the predictions of prospect theory, as can be verified by simply applying prospect t...

Abstract Traditional exhaustive search methods have high time complexity in solving multilevel threshold problems. To address this problem, a Levy flight based firefly algorithm called LFA is proposed. Otsu regard as its objective function. A series of standard test images were used to evaluate the performance algorithm. The Peak signal noise ratio(PSNR) and Structural similarity index (SSIM) a...

In this paper, by using contraction principle, fractional calculus and stochastic analysis, we study the existence uniqueness of (weighted pseudo) almost automorphic solutions in distribution for differential equations driven L?vy noise. An example is presented to illustrate application abstract results.
