Mean Flow from Phase Averages in the 2D Boussinesq Equations
Atmosphere, 2023 The atmosphere and ocean are described by highly oscillatory PDEs that challenge both our understanding of their dynamics and their numerical approximation.

Zero-Hopf Bifurcations of 3D Quadratic Jerk System
Mathematics, 2020 This paper is devoted to local bifurcations of three-dimensional (3D) quadratic jerk system. First, we start by analysing the saddle-node bifurcation. Then we introduce the concept of canonical system.

On Hamiltonian Averaging Theories and Resonance [PDF]
International Astronomical Union Colloquium, 1997 AbstractIn this article, we review the construction of Hamiltonian perturbation theories with emphasis on Hori’s theory and its extension to the case of dynamical systems with several degrees of freedom and one resonant critical angle. The essential modification is the comparison of the series terms according to the degree of homogeneity in both and a

3-dimensional Hopf bifurcation via averaging theory [PDF]
Discrete & Continuous Dynamical Systems - A, 2007 We consider the Lorenz system $\dot x = \s (y-x)$, $\dot y =rx -y-xz$ and $\dot z = -bz + xy$; and the Rossler system $\dot x = -(y+z)$, $\dot y = x +ay$ and $\dot z = b-cz + xz$. Here, we study the Hopf bifurcation which takes place at $q_{\pm}=(\pm\sqrt{br-b},\pm\sqrt{br-b},r-1),$ in the Lorenz case, and at $s_{\pm}=(\frac{c+\sqrt{c^2-4ab}}{2},-

Bayesian model averaging for analysis of lattice field theory results [PDF]
Physical Review D, 2020 Statistical modeling is a key component in the extraction of physical results from lattice field theory calculations. Although the general models used are often strongly motivated by physics, their precise form is typically ill-determined, and many model

Averaging theory at any order for computing limit cycles of discontinuous piecewise differential systems with many zones [PDF]
, 2016 This work is devoted to study the existence of periodic solutions for a class of e -family of discontinuous differential systems with many zones. We show that the averaged functions at any order control the existence of crossing limit cycles for systems ...

Modeling Nondilute Species Transport Using the Thermodynamically Constrained Averaging Theory
Water Resources Research, 2018 Nondilute transport in porous media results in fronts that are much sharper in space and time than the corresponding transport of a conservative, nonreactive dilute species.

System Reliability Analysis Based On Weibull Distribution and Hesitant Fuzzy Set [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2018 This work deals with the hesitant fuzzy number and averaging operator and fuzzy reliability with the help of Weibull lifetime distribution. Fuzzy reliability function and triangular hesitant fuzzy number also computed with α-cut set of the proposed ...
