A comprehensive summary and update is given of Brouwers’ statistical model that was developed during the previous decade. The presented recapitulated valid for general inhomogeneous anisotropic velocity statistics are typical turbulence. It succeeds improves semiempirical heuristic models century. based on a Langevin diffusion equation which derivation involves (i) application principles physic...

We have investigated the basic statistics of cosmological dispersion measure (DM) -- such as its mean, variance, probability distribution, angular power spectrum and correlation function using state-of-the-art hydrodynamic simulations, IllustrisTNG300, for fast radio burst (FRB) cosmology. To model DM statistics, we first measured free-electron abundance spatial fluctuations. The turns out to b...

The dispersion relation is fundamental to a physical phenomenon that develops in both space and time. This equation connects the spatial and temporal frequencies involved in the dynamic process through the material constants. Electromagnetic plane waves propagating in homogeneous media are bound by simple dispersion relation, which sets the magnitude of the spatial frequency, k, as being propor...

Knowledge of aircraft InfraRed Signature (IRS) is indispensable for assessing their detection probability, and thus their survivability in an hostile environment. By signature, we mean all the quantities for predicting the signal that would be observed by an optronic sensor when the aircraft is in its surroundings. For many reasons, the experimental approach is generally not feasible to evaluat...

in this study the effect of using multi-walled carbon nanotube (mwcnt) on flexural and compressive strengths, ultimate displacement and energy absorption capability of standard cement mortar considering different weight percentages of nanotubes as well as different dispersion methods has been investigated. influential point in adding nanotubes to the composites is their proper dispersion, which...

Pulse propagation in optical fiber links with randomness in the dispersion is investigated theoretically and numerically for systems with and without dispersion management. The main effects of locally correlated noise are inevitable pulse destruction and statistical broadening. However, periodic/quasi-periodic management of fiber randomness, achieved by setting the accumulated dispersion to its...
