The Proximal Average: Basic Theory [PDF]

open access: yesSIAM Journal on Optimization, 2008
The notion of proximal average of two convex functions introduced by \textit{H. H. Bauschke, E. Matoušková} and \textit{S. Reich} [Nonlinear Anal., Theory Methods Appl. 56A, No. 5, 715--738 (2004; Zbl 1059.47060)] is extended to finitely many convex functions on a real Hilbert space.

Aperture averaging: theory and measurements [PDF]

open access: yesSPIE Proceedings, 2004
Atmospheric laser communications using direct-detection systems do suffer from severe degradation caused by scintillation. Because the atmospheric cut-off frequency can be as low as 100 Hz, temporal averaging is not applicable in high-speed communications.

On the torus bifurcation in averaging theory [PDF]

open access: yesJournal of Differential Equations, 2020
In this paper, we take advantage of the averaging theory to investigate a torus bifurcation in two-parameter families of 2D nonautonomous differential equations. Our strategy consists in looking for generic conditions on the averaged functions that ensure the existence of a curve in the parameter space characterized by a Neimark-Sacker bifurcation in ...

On Hamiltonian Averaging Theories and Resonance [PDF]

open access: yesInternational 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

On the theory of average case complexity

open access: yes[1989] Proceedings. Structure in Complexity Theory Fourth Annual Conference, 1989
The paper takes the next step in developing the theory of average case complexity initiated by L . A. Levin. A distributional decision problem is a pair \((D,\mu)\) where \(D\) is the set of strings and \(\mu\) is a (distribution) function from strings to the unit interval \([0,1]\).

Adaptive tracking control of flapping wing micro-air vehicles with averaging theory

open access: yesCAAI Transactions on Intelligence Technology, 2018
An input constrained adaptive tracking controller is designed for flapping micro aerial vehicles, wherein the moving averaging filter is adopted to estimate the averaged states of the system.

Limit cycles of Liénard polynomial systems type by averaging method

open access: yesMoroccan Journal of Pure and Applied Analysis, 2020
We apply the averaging theory of first and second order for studying the limit cycles of generalized polynomial Linard systems of the ...

Mean Flow from Phase Averages in the 2D Boussinesq Equations

open access: yesAtmosphere, 2023
The atmosphere and ocean are described by highly oscillatory PDEs that challenge both our understanding of their dynamics and their numerical approximation.
