Impact of intrinsic localized modes of atomic motion on materials properties
atomic motion materials properties
<
2010/4/1
Recent neutron and x-ray scattering measurements show intrinsic localized modes (ILMs) in metallic uranium and ionic sodium iodide. Here, the role ILMs play in the behavior of these materials is exami...
Correlations of mesospheric winds with subtle motion of the Arctic polar vortex

2010/2/1
This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings. A ground b...
Optical-Wavelength Paramagnetic Phaser (Lecture Notes). Section 3.1. Nonlinear Balance Equations of Motion
Optical-Wavelength Paramagnetic Phaser Nonlinear Balance Equations class-B lasers
<
2010/4/1
In this work I present a detailed description of the simplest nonlinear model for an optical wavelength paramagnetic phaser, which is an acoustic analog of the class-B lasers. Despite of its simplicit...
Further remarks on mixed fractional Brownian motion
Fractional Brownian Motion Fractional Calculus
<
2010/9/15
We study linear combinations of independent fractional Brownian motions and generalize several recent results from [10] and [17]. As a first new result we calculate explicitly the Hausdorff dimension ...
The quasi-static approximation of the spring-slider motion
quasi-static approximation spring-slider motion
<
2009/11/16
The spring-slider is a simple dynamical system consisting in a massive block sliding with friction and pulled through a spring at a given velocity. Understanding the block motion is fundamental for st...
Collective versus Single--Particle Motion in Quantum Many--Body Systems from the Perspective of an Integrable Model
Single--Particle Motion Quantum Many--Body Systems Integrable Model
<
2010/4/8
We study the emergence of collective dynamics in the integrable Hamiltonian system of two finite ensembles of coupled harmonic oscillators. After identification of a collective degree of freedom, the ...
The role of nonlinear Landau damping and the bounced motion of protons in the formation of dissipative structures in the solar wind plasma

<
2009/11/13
The present work examines the effects arising from the nonlinear Landau damping and the bounced motion of protons (trapped in the mirror geometry of the geomagnetic field) in the formation of nonlinea...
Recently found unstable time-periodic solutions to the incompressible Navier-Stokes equation are reviewed to discuss their relevance to plane Couette turbulence and isotropic turbulence. It is shown t...
Experimental study of nonlinear interaction of plasma flow with charged thin current sheets:1.Boundary structure and motion
nonlinear interaction plasma flow thin current sheets Boundary structure
<
2009/11/9
We study plasma transport at a thin magnetopause (MP), described hereafter as a thin current sheet (TCS), observed by Cluster at the southern cusp on 13 February 2001 around 20:01 UT. The Cluster obse...
A STOCHASTIC MODEL DESCRIBING THE WATER MOTION IN A RIVER
STOCHASTIC MODEL WATER MOTION
<
2009/10/29
In this paper a mathematical model for the movement of water particles
in a river is constructed.
Using the model it will be possible to find an analytic expression for the
distribution function F(...
Kinematic Model of River Ice Motion During Dynamic Breakup
Kinematic Model River Ice Motion Dynamic Breakup
<
2009/10/26
We begin a study of the dynamics of ice motion during river breakup by
formulating a kinematic model. Ice continuity equations are applied to relate
the speeds of a breaking front, a convergence fro...
