Short-range correlations in modified planar rotator model

Publikováno v: Journal of Physics: Conference Series 633 (2015) 012105

We introduce a model inspired from statistical physics that is shown to display flexible short-range spatial correlations which are potentially useful in geostatistical modeling. In particular, we consider a suitably modified planar rotator or XY mod

Environmental Time Series Interpolation Based on Spartan Random Processes

Autor: Žukovič, M., Hristopulos, D. T.

Publikováno v: Atmospheric Environment 42 (2008) 7669

In many environmental applications, time series are either incomplete or irregularly spaced. We investigate the application of the Spartan random process to missing data prediction. We employ a novel modified method of moments (MMoM) for parameter in

Spartan Random Processes in Time Series Modeling

Autor: Zukovic, M., Hristopulos, D. T.

Publikováno v: Physica A 387 3995 (2008)

A Spartan random process (SRP) is used to estimate the correlation structure of time series and to predict (extrapolate) the data values. SRP's are motivated from statistical physics, and they can be viewed as Ginzburg-Landau models. The temporal cor

Fast Spatial Prediction from Inhomogeneously Sampled Data Based on Generalized Random Fields with Gibbs Energy Functionals

Autor: Hristopulos, D. T., Elogne, S. N.

An explicit optimal linear spatial predictor is derived. The spatial correlations are imposed by means of Gibbs energy functionals with explicit coupling coefficients instead of covariance matrices. The model inference process is based on physically

A discrete nonlinear mass transfer equation with applications in solid-state sintering of ceramic materials

Autor: Hristopulos, D. T., Leonidakis, L., Tsetsekou, A.

Publikováno v: European Physical Journal B - Condensed Matter Physics, 50(1-2), 83-87 (2006)

The evolution of grain structures in materials is a complex and multiscale process that determines the material's final properties. Understanding the dynamics of grain growth is a key factor for controlling this process. We propose a phenomenological

Report

Spatial Random Field Models Inspired from Statistical Physics with Applications in the Geosciences

Autor: Hristopulos, D. T.

Publikováno v: Physica A: Statistical Mechanics and its Applications, 365(1-2), 211-216 (2006)

The spatial structure of fluctuations in spatially inhomogeneous processes can be modeled in terms of Gibbs random fields. A local low energy estimator (LLEE) is proposed for the interpolation (prediction) of such processes at points where observatio
