On limit theorems for random fields

Lietuvos Matematikos Rinkinys, 2009
A complete separable metric space of functions defined on the positive quadrant of the plane is constructed. The characteristic property of these functions is that at every point x there exist two lines intersecting at this point such that limits limy→x ...

Statistical properties of effective elastic moduli of random cubic polycrystals

Mechanics & Industry, 2023
The homogenized elastic properties of polycrystals depend on the grain morphology and crystallographic orientations. For simplification purposes, the orientations of the grains are usually considered three independent Euler angles.

Associative Hierarchical Random Fields

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2014
This paper makes two contributions: the first is the proposal of a new model-The associative hierarchical random field (AHRF), and a novel algorithm for its optimization; the second is the application of this model to the problem of semantic segmentation.

Asymptotic Behavior of a Nonparametric Estimator of the Renewal Function for Random Fields

Mathematics, 2023
In this paper, we study the asymptotic normality of a nonparametric estimator of the renewal function associated with a sequence of absolutely continuous nonnegative two-dimensional random fields.

Model-Based and Model-Free Point Prediction Algorithms for Locally Stationary Random Fields

Applied Sciences, 2023
The Model-Free Prediction Principle has been successfully applied to general regression problems, as well as problems involving stationary and locally stationary time series.

Large scale random fields generation using localized Karhunen–Loève expansion

Advanced Modeling and Simulation in Engineering Sciences, 2018
In this paper the generation of random fields when the domain is much larger than the characteristic correlation length is made using an adaptation of the Karhunen–Loève expansion (KLE).

Influence of Yield Strength Variability over Cross-Section to Steel Beam Load-Carrying Capacity

Nonlinear Analysis, 2005
Authors of article analysed influence of variability of yield strength over cross-section of hot rolled steel member to its load-carrying capacity. In calculation models, the yield strength is usually taken as constant.

First-order planar autoregressive model

Modern Stochastics: Theory and Applications
This paper establishes the conditions for the existence of a stationary solution to the first-order autoregressive equation on a plane as well as properties of the stationary solution.

ESTIMATION OF SAMPLE SPACING IN STOCHASTIC PROCESSES

Image Analysis and Stereology, 2017
Motivated by applications in electron microscopy, we study the situation where a stationary and isotropic random field is observed on two parallel planes with unknown distance. We propose an estimator for this distance.
