Slowly varying
WebbIf ˆ= 0, the function Uis said to be slowly varying at in nity. If ˆ= 1 , the function Uis said to be rapidly varying at in nity. Examples: The functions xˆand xˆlog(1+x) have regular variation of order ˆat in nity. The function arctanxis … Webb15 maj 1970 · Abstract. A WKB-perturbation technique is applied to study the slow modulation of a Stokes wave train on the surface of water. It is found that new terms directly representing modulation rates ...

WebbAbstract. 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 ... Webb3 dec. 2024 · However, I am wondering if this uniform convergence (or, in fact, some other property of slowly-varying functions such as their explicit representation in terms of the exponential function, see below) can be exploited to prove something like the following:
WebbThis article proposes a deep learning (DL)-based control algorithm-DL velocity-based model predictive control (VMPC)-for reducing traffic congestion with slowly time-varying traffic signal controls. This control algorithm consists of system identification using DL and traffic signal control using VM … WebbDIFFERENCES OF SLOWLY VARYING FUNCTIONS 481 For the converse, suppose L f OPq.Then we shall find F and G nondecreasing such that L s F q G with F and G not slowly varying.

Assimilating temperature data into two different global climate models changes the strength and/or spatial pattern of east-west winds at low altitudes. WebbSV class, the ƒclasses (see e.g. [3], or [5]), and the Beurling classes, the slowly varying one (see e.g. [5]) that contains the SV class, or the RV one (see [6]). It is worth noticing that the Beurling theory includes the Karamata theory (see [6]). In this paper, we propose a new extension of the RV class, defined in terms of the asymp-
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 ...
