Estimation of Kramers-Moyal coefficients at low sampling rates

open access: yes, 2011
A new optimization procedure for the estimation of Kramers-Moyal coefficients from stationary, one-dimensional, Markovian time series data is presented.

Regeneration of Stochastic Processes: An Inverse Method

open access: yes, 2005
We propose a novel inverse method that utilizes a set of data to construct a simple equation that governs the stochastic process for which the data have been measured, hence enabling us to reconstruct the stochastic process. As an example, we analyze the

Model-mapped RPA for determining the effective Coulomb interaction

open access: yes, 2017
We present a new method to obtain interaction part of a model Hamiltonian from the result of the first-principles calculation. The effective interaction contained in the model is determined based on the random phase approximation (RPA).

Stochastic Analysis and Regeneration of Rough Surfaces

open access: yes, 2003
We investigate Markov property of rough surfaces. Using stochastic analysis we characterize the complexity of the surface roughness by means of a Fokker-Planck or Langevin equation.

Convergence analysis of domain decomposition based time integrators for degenerate parabolic equations

open access: yes, 2017
Domain decomposition based time integrators allow the usage of parallel and distributed hardware, making them well-suited for the temporal discretization of parabolic systems, in general, and degenerate parabolic problems, in particular.

Finite sampling interval effects in Kramers-Moyal analysis

open access: yes, 2009
Large sampling intervals can affect reconstruction of Kramers-Moyal coefficients from data. A new method, which is direct, non-stochastic and exact up to numerical accuracy, can estimate these finite-time effects.

Adaptive optics near infrared integral field spectroscopy of NGC 2992

open access: yes, 2010
NGC 2992 is an intermediate Seyfert 1 galaxy showing outflows on kilo parsec scales which might be due either to AGN or starburst activity. We therefore aim at investigating its central region for a putative starburst in the past and its connection to ...

Nomadismes et identités transfrontalières – Anzaldúa avec Nietzsche

open access: yesAmerika, 2011
This article centers upon an analysis of the conceptions of subjectivity theorized by Friedrich Nietzsche and Gloria Anzaldúa. Beyond the basic premise of a comparative method, the approach proposed here consists in elucidating the critical strategies ...
