Parametric evaluation of 3D dispersion of rockfall trajectories [PDF]

Natural Hazards and Earth System Sciences, 2004
The capability of evaluating and managing rockfall related risks is largely based on numerical modelling. Nevertheless, the reliability and accuracy of rockfall models is greatly affected by the strong uncertainty and spatial variability which ...

Design of photonic crystal fibers with flat dispersion and three zero dispersion wavelengths for coherent supercontinuum generation in both normal and anomalous regions

Results in Physics, 2021
A photonic crystal fiber (PCF) structure with three-zero dispersion wavelengths (ZDWs) and a flat dispersion curve was designed by adjusting the structural parameters (the diameters of small air holes inserted between standard lattices in the first and ...

What Do We Know About the Strange Magnetic Radius?

, 2002
We analyze the q^2-dependence of the strange magnetic form factor, \GMS(q^2), using heavy baryon chiral perturbation theory (HBChPT) and dispersion relations.

Hierarchical Bayesian inference of the Initial Mass Function in Composite Stellar Populations [PDF]

, 2017
The initial mass function (IMF) is a key ingredient in many studies of galaxy formation and evolution. Although the IMF is often assumed to be universal, there is continuing evidence that it is not universal.

Fast and broadband fiber dispersion measurement with dense wavelength sampling

, 2014
We report on a method to obtain dispersion measurements from spectral-domain low-coherence interferograms which enables high accuracy (~ps/(nm·km)), broadband measurements and the determination of very dense (up to 20 points/nm over 500 nm) data sets for

Doping dependent plasmon dispersion in 2H-transition metal dichalcogenides [PDF]

, 2016
We report the behavior of the charge carrier plasmon of 2H-transition metal dichalcogenides (TMDs) as a function of intercalation with alkali metals. Intercalation and concurrent doping of the TMD layers have a substantial impact on plasmon energy and ...

Morphology and scaling in the noisy Burgers equation: Soliton approach to the strong coupling fixed point

, 1997
The morphology and scaling properties of the noisy Burgers equation in one dimension are treated by means of a nonlinear soliton approach based on the Martin-Siggia-Rose technique. In a canonical formulation the strong coupling fixed point is accessed by

The correlation between black hole mass and bulge velocity dispersion in hierarchical galaxy formation models [PDF]

, 2000
Recent work has demonstrated that there is a tight correlation between the mass of a black hole and the velocity dispersion of the bulge of its host galaxy. We show that the model of Kauffmann & Haehnelt, in which bulges and supermassive black holes both

Laser Field Distribution in Photonic Crystal Fiber With Triple Zero Dispersion Wavelengths [PDF]

مجلة التربية والعلم, 1999
The aim of this work is to study the properties of the photonic crystal fibers (PCFs) and the laser field distribution at the zero dispersion wavelengths (ZDWs). Three PCFs are proposed, all the PCFs have one missing hole and one ring of holes around the
