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.

Random Scalar Fields and Hyperuniformity

, 2017
Disordered many-particle hyperuniform systems are exotic amorphous states of matter that lie between crystals and liquids. Hyperuniform systems have attracted recent attention because they are endowed with novel transport and optical properties. Recently,

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.

Ergodicity and Gaussianity for Spherical Random Fields [PDF]

, 2009
We investigate the relationship between ergodicity and asymptotic Gaussianity of isotropic spherical random fields, in the high-resolution (or high-frequency) limit.

On Pfaffian random point fields

, 2013
We study Pfaffian random point fields by using the Moore-Dyson quaternion determinants. First, we give sufficient conditions that ensure that a self-dual quaternion kernel defines a valid random point field, and then we prove a CLT for Pfaffian point ...

Post-failure analysis of landslides in spatially varying soil deposits using stochastic material point method

Rock and Soil Mechanics, 2022
This paper presents the probabilistic analysis of landslides in spatially variable soil deposits, modeled by a stochastic framework which integrates the random field theory with generalized interpolation material point method (GIMP).

Screening of charged singularities of random fields [PDF]

, 2004
Many types of point singularity have a topological index, or 'charge', associated with them. For example the phase of a complex field depending on two variables can either increase or decrease on making a clockwise circuit around a simple zero, enabling ...

Optimal Nonlinear Prediction of Random Fields on Networks [PDF]

Discrete Mathematics & Theoretical Computer Science, 2003
It is increasingly common to encounter time-varying random fields on networks (metabolic networks, sensor arrays, distributed computing, etc.).This paper considers the problem of optimal, nonlinear prediction of these fields, showing from an information ...

Representation of Gaussian Isotropic Spin Random Fields [PDF]

, 2014
We develop a technique for the construction of random fields on algebraic structures. We deal with two general situations: random fields on homogeneous spaces of a compact group and in the spin-line bundles of the 2-sphere.
