Slowly varying
WebbIn a first step, no torque is applied to the particle, so that its motion is described by a Hamiltonian with slowly varying parameters. We show that the torque applied to the satellite, as measured by ∈ s = j s / ( n s J s) induces an distortion of the phase space which is entirely described by an asymmetry coefficient α = ∈ s /μ, where ... Webb17 jan. 2024 · We focus on slowly-varying atmospheric phenomena (timescales from 10 Mars days to a season). Assimilating temperature data into two different global climate models changes the strength and/or spatial pattern of east-west winds at low altitudes.

Webbchannel of constant cross section but varying curvature. In both cases, under the assumption of an arbitrary but slowly varying cross section and curvature, respectively, we show that the velocity component perpendicular to the constraint plane cannot be zero unless cross section and curvature are both constant, and therefore the flow is fully ... Webb10 juni 2011 · The concepts of slowly varying, regular varying and second order regular varying functions are used in extreme value statistics to provide regularity conditions on the behavior of the tail of a distribution function to be able to prove theorems. They can be thought of as smoothness conditions for the tail at infinity.
WebbIn real analysis, a branch of mathematics, a slowly varying function is a function resembling a function converging at infinity. A regularly varying function resembles a … WebbThe slowly varying solitary wave is constructed as an asymptotic solution of the variable coefficient Korteweg-de Vries equation. A multiple scale method is used to determine the amplitude and phase of the wave to the second order in the perturbation parameter.

In the context of Bose-Einstein condensate (BEC), it is often referred to as the Gross-Pitaevskii equation (GPE).
Webb5 feb. 2024 · We study the Quasi-Periodic Pulsations (QPPs) of an M4.4 class solar flare, which occurred in active region NOAA 11165 on 8 March 2011. With the Fast Fourier Transform (FFT) method, we decompose the flare light curve into fast- and slowly-varying components. The 100 s (0.01 Hz) is selected as the cutoff threshold between the fast- …

We obtain existence and bifurcation theorems for homoclinic orbits in three-dimensional flows that are perturbations of families of planar Hamiltonian systems. The perturbations may or may not depend explicitly on time. We show how the results on periodic orbits of the preceding paper are related to the present homoclinic results, and ... chilling temperatureWebbParameter-dependent equilibrium solutions are analyzed as the parameter slowly varies through critical values corresponding to a bifurcation or to a jump phenomena.
