We consider the modeling of light beams propagating in highly forward-peaked turbulent media by fractional Fokker-Planck equations and their approximations Fermi pencil beam models. We obtain an error estimate a 1-Wasserstein distance for latter model showing that spreading is well captured pencil-beam approximation small diffusion limit.
In this paper, an efficient localized meshless method based on the space–time Gaussian radial basis functions is discussed. We aim to deal with left Riemann–Liouville space fractional derivative wave and damped equation in high-dimensional space. These significant problems as anomalous models could arise several research fields of science, engineering, technology. Since explicit solution such e...
We report the observation of defects with fractional topological charges (disclinations) in square and hexagonal patterns as numerical solutions of several generic equations describing many pattern-forming systems: Swift-Hohenberg equation, damped Kuramoto-Sivashinsky equation, as well as nonlinear evolution equations describing large-scale Rayleigh-Benard and Marangoni convection in systems wi...
We review the progress achieved in optical information processing during the last decade by applying fractional linear integral transforms. The fractional Fourier transform and its applications for phase retrieval, beam characterization, space-variant pattern recognition, adaptive filter design, encryption, watermarking, and so forth is discussed in detail. A general algorithm for the fractiona...

ABSTRACT The prototype superconducting cavity system for CESRPhase III was tested in CESR in August 1994. The performance of the system was very gratifying. The cavity operated gradients of 4.5-6 MV/m and accelerated beam currents up to 220 mA. This current is a factor of 3 above the world record 67 mA for SRF[1]. The high circulating beam current did not increase the heat load or present any d...
