Scaling Analysis and Evolution Equation of the North Atlantic Oscillation Index Fluctuations [PDF]

open access: yes, 2004
The North Atlantic Oscillation (NAO) monthly index is studied from 1825 till 2002 in order to identify the scaling ranges of its fluctuations upon different delay times and to find out whether or not it can be regarded as a Markov process.

Thermal explosion in oscillating ambient conditions [PDF]

open access: yesScientific Reports, 2016
AbstractThermal explosion problem for a medium with oscillating ambient temperature at its boundaries is considered. This is a new problem in thermal explosion theory, not previously considered in a distributed system formulation, but important for combustion and fire science. It describes autoignition of wide range of fires (such as but not limited to

Oscillation and non-oscillation of half-linear differential equations with coeffcients determined by functions having mean values

open access: yesOpen Mathematics, 2018
The paper belongs to the qualitative theory of half-linear equations which are located between linear and non-linear equations and, at the same time, between ordinary and partial differential equations.

Estimating Phase Amplitude Coupling between Neural Oscillations Based on Permutation and Entropy

open access: yesEntropy, 2021
Cross-frequency phase–amplitude coupling (PAC) plays an important role in neuronal oscillations network, reflecting the interaction between the phase of low-frequency oscillation (LFO) and amplitude of the high-frequency oscillations (HFO).

Quartz oscillators: deriving oscillation condition by symbolic calculus [PDF]

open access: yes10th International Conference on European Frequency and Time, 1996
This paper presents the method used to derive the oscillation condition by using symbolic calculus. The program is based on the full nonlinear Barkhausen criterion method. The behaviour of an oscillator is described by a complex polynomial called the characteristic polynomial.

Models of dynamic process of forming stugotine [PDF]

open access: yesTehnika, 2017
The oscillating elements obradog system in principle is conditional on the dynamic character of the process of formation filings. It is necessary to let the frequency of natural oscillation elements of the system tool - workpiece - accessories - machine ...

Likelihood-free inference of experimental Neutrino Oscillations using Neural Spline Flows

open access: yes, 2020
In machine learning, likelihood-free inference refers to the task of performing an analysis driven by data instead of an analytical expression. We discuss the application of Neural Spline Flows, a neural density estimation algorithm, to the likelihood ...

Euler type linear and half-linear differential equations and their non-oscillation in the critical oscillation case

open access: yesJournal of Inequalities and Applications, 2019
This paper is devoted to the analysis of the oscillatory behavior of Euler type linear and half-linear differential equations. We focus on the so-called conditional oscillation, where there exists a borderline between oscillatory and non-oscillatory ...

Oscillations Conditions in Homogenous Systems [PDF]

open access: yesIFAC Proceedings Volumes, 2010
The problem of oscillations detection for nonlinear systems is addressed. The notion of homogeneity in bi-limit from (Andrieu, et al., 2008) is extended to local homogeneity. Next, sufficient conditions of oscillations existence for locally homogeneous systems are formulated.
