Improvements in Turbulent Jet Particle Dispersion Modeling and Its Validation with DNS

open access: yesAtmosphere
Particle dispersion models (PDMs) are essential to capture the influence of unresolved turbulent eddies on particle transport in computational fluid dynamics (CFD) simulations.

Dynamical behavior of solitons of the perturbed nonlinear Schrödinger equation and microtubules through the generalized Kudryashov scheme

open access: yesResults in Physics, 2022
The perturbed nonlinear Schrödinger (NLS) equation and the nonlinear radial dislocations model in microtubules (MTs) are the underlying frameworks to simulate the dynamic features of solitons in optical fibers and the functional aspects of microtubule ...

No wide spread of stellar ages in the Orion Nebula Cluster [PDF]

open access: yes, 2011
The wide luminosity dispersion seen for stars at a given effective temperature in the H-R diagrams of young clusters and star forming regions is often interpreted as due to significant (~10 Myr) spreads in stellar contraction age.

On Some Layer‐Based Risk Measures with Applications to Exponential Dispersion Models [PDF]

open access: yesJournal of Probability and Statistics, 2010
Layer‐based counterparts of a number of well‐known risk measures have been proposed and studied. Namely, some motivations and elementary properties have been discussed, and the analytic tractability has been demonstrated by developing closed‐form expressions in the general framework of exponential dispersion models.

Reactimeter dispersion equation

open access: yesNuclear Energy and Technology, 2016
The aim of this work is to derive and analyze a reactimeter metrological model in the form of the dispersion equation which connects reactimeter input/output signal dispersions with superimposed random noise at the inlet.

Clustering dynamics of Lagrangian tracers in free-surface flows

open access: yes, 2002
We study the formation of clusters of passive Lagrangian tracers in a non-smooth turbulent flow in a flat free-slip surface as a model for particle dynamics on free surfaces. Single particle and pair dispersion show different behavior for short and large

Bayesian Credibility for GLMs [PDF]

open access: yes, 2018
We revisit the classical credibility results of Jewell and B\"uhlmann to obtain credibility premiums for a GLM using a modern Bayesian approach. Here the prior distributions can be chosen without restrictions to be conjugate to the response distribution.

First arriving signals in layered waveguides. An approach based on dispersion diagrams

open access: yes, 2016
The first arriving signal (FAS) in a layered waveguide is investigated. It is well known that the velocity of such a signal is close to the velocity of the fastest medium in the waveguide, and it may be bigger than the fastest group velocity given by the

Ion temperature gradient mode and its solitons with regularized κ-distributed electrons

open access: yesAIP Advances, 2022
The linear and the non-linear behaviors of the ion temperature gradient (ITG) mode in a plasma with regularized κ-distributed electrons are investigated using the fluid model.

Nonlinear dispersion in parabolic law medium and its optical solitons

open access: yesResults in Physics, 2021
This paper studies the optical soliton solutions of a nonlinear Schrödinger equation (NLSE) involving parabolic law of nonlinearity with the presence of nonlinear dispersion by using the generalized auxiliary equation technique.
