Weakly resonant double Hopf bifurcation in coupled nonlinear systems with delayed freedback and application of homotopy analysis method

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2019
In this paper, we study the dynamical behaviors of coupled nonlinear systems with delay coupling by the multiple scales method and the homotopy analysis method.

Algorithmic Foundation of Spectral Rarefaction for Measuring Satellite Imagery Heterogeneity at Multiple Spatial Scales

open access: yesSensors, 2009
Measuring heterogeneity in satellite imagery is an important task to deal with. Most measures of spectral diversity have been based on Shannon Information theory.

Valuation of Credit Derivatives with Multiple Time Scales in the Intensity Model

open access: yes, 2014
We propose approximate solutions for pricing zero-coupon defaultable bonds, credit default swap rates, and bond options based on the averaging principle of stochastic differential equations.

Introduction to the method of multiple scales

open access: yes, 2013
Earlier versions of these lecture notes have been used at the Cork Summerschool on Theory and Mathematics Modelling of Ultrashort Pulse Propagation (2013), and as a part of a graduate course in the theory of nonlinear waves in the period 2014-2016. This version has an improved typography and numerous typoes has been corrected. It also has been extended

Application of the method of multiple scales to unravel energy exchange in nonlinear locally resonant metamaterials [PDF]

open access: yes, 2018
In this paper, the effect of weak nonlinearities in 1D locally resonant metamaterials is investigated via the method of multiple scales. Commonly employed to the investigate the effect of weakly nonlinear interactions on the free wave propagation through

Multi-Scale Pixel-Based Image Fusion Using Multivariate Empirical Mode Decomposition

open access: yesSensors, 2015
A novel scheme to perform the fusion of multiple images using the multivariate empirical mode decomposition (MEMD) algorithm is proposed. Standard multi-scale fusion techniques make a priori assumptions regarding input data, whereas standard univariate ...

Levellism and the Method of Abstraction by

open access: yes, 2008
The use of “levels of abstraction ” in philosophical analysis (levellism) has recently come under attack. In this paper, we argue that a refined version of epistemological levellism should be retained as a fundamental method, which we call the method of ...

Limitations of the Method of Multiple-Time-Scales

open access: yes, 2002
In the Method of Multiple-Time-Scales (MMTS), the introduction of independent time scales and the elimination of secular terms in the fast time variable, T0 = t, lead to the well-known solvability conditions. Starting from first order, free terms (solutions of the unperturbed equations) emerge in every order in the expansion of the approximate solution.

Method of multiple scales in scalar field cosmology

open access: yes, 2021
In this work, the method of multiple scales is applied to analysis of cosmological dynamics. The method is used to construct solutions to the dynamic equations of the Universe filled with a scalar field in the Friedman-Robertson-Walker metric.
