A new perspective on the Propagation-Separation approach: Taking advantage of the propagation condition [PDF]

open access: yes, 2013
The Propagation-Separation approach is an iterative procedure for pointwise estimation of local constant and local polynomial functions. The estimator is defined as a weighted mean of the observations with data-driven weights.

Smooth Energy: Cosmological Constant or Quintessence? [PDF]

open access: yesThe Astrophysical Journal, 2001
For a flat universe presently dominated by smooth energy, either cosmological constant (LCDM) or quintessence (QCDM), we calculate the asymptotic collapsed mass fraction as a function of the present ratio of smooth energy to matter energy, 0. Identifying the normalized collapsed fraction as a conditional probability for habitable galaxies, we observe ...

Adaptive inexact fast augmented Lagrangian methods for constrained convex optimization [PDF]

open access: yes, 2015
In this paper we analyze several inexact fast augmented Lagrangian methods for solving linearly constrained convex optimization problems. Mainly, our methods rely on the combination of excessive-gap-like smoothing technique developed in [15] and the ...

Numerical Analyses of Weakly Nonlinear Velocity-Density Coupling [PDF]

open access: yes, 2001
We study evolution of various statistical quantities of smoothed cosmic density and velocity fields using N-body simulations. The parameter $C\equiv /( )$ characterizes nonlinear coupling of these two fields and determines behavior of bulk velocity ...

Application of the curvature smoothing technique for four-node quadrilateral Reissner-Mindlin plate element

open access: yesVietnam Journal of Mechanics, 2007
A quadrilateral element with smoothed curvatures for Reissner-Mindlin structure plates is proposed. A curvature matrix at an arbitrary point is normalized by a non-local approximation over a smoothing function.

Monotonicity preserving approximation of multivariate scattered data [PDF]

open access: yes, 2005
This paper describes a new method of monotone interpolation and smoothing of multivariate scattered data. It is based on the assumption that the function to be approximated is Lipschitz continuous.
