Investigating the Number of Monte Carlo Simulations for Statistically Stationary Model Outputs

Axioms, 2023
The number of random fields required to capture the spatial variability of soil properties and their impact on the performance of geotechnical systems is often varied.

Decomposed Mean Euler-Poincaré Characteristic Model for a Non-Gaussian Physiological Random Field

IEEE Access, 2021
This paper introduces a new approach of the mean Euler-Poincaré characteristic for nonGaussian random fields (NGRF), which is based on the decomposition by a basic function named motherwave.

Surface criticality in random field magnets [PDF]

, 2005
The boundary-induced scaling of three-dimensional random field Ising magnets is investigated close to the bulk critical point by exact combinatorial optimization methods.

Random Field-Based Time-Dependent Reliability Analyses of a PSC Box-Girder Bridge

Applied Sciences, 2019
The parameters affecting structural reliability are usually regarded as independent random variables in the current reliability analyses of bridge structures while the randomness of these structural parameters in spatial distribution is neglected.

Seepage–Fractal Model of Embankment Soil and Its Application

Fractal and Fractional, 2022
Over time and across space, the hydraulic conductivity, fractal dimension, and porosity of embankment soil have strong randomness, which makes analyzing seepage fields difficult, affecting embankment risk analysis and early disaster warning.

Mean field conditions for coalescing random walks [PDF]

, 2013
The main results in this paper are about the full coalescence time $\mathsf{C}$ of a system of coalescing random walks over a finite graph $G$. Letting $\mathsf{m}(G)$ denote the mean meeting time of two such walkers, we give sufficient conditions under ...

Review of Recent Developments in the Random-Field Ising Model [PDF]

, 2017
A lot of progress has been made recently in our understanding of the random-field Ising model thanks to large-scale numerical simulations. In particular, it has been shown that, contrary to previous statements: the critical exponents for different ...

Restoration of dimensional reduction in the random-field Ising model at five dimensions. [PDF]

Physical Review E, 2016
The random-field Ising model is one of the few disordered systems where the perturbative renormalization group can be carried out to all orders of perturbation theory.

Multi-field Inflation with a Random Potential [PDF]

, 2009
Motivated by the possibility of inflation in the cosmic landscape, which may be approximated by a complicated potential, we study the density perturbations in multi-field inflation with a random potential.
