Differential Equations and Nonlinear Mechanics, 2007 The stochastic finite element method (SFEM) is employed for solving stochastic one-dimension time-dependent differential equations with random coefficients. SFEM is used to have a fixed form of linear algebraic equations for polynomial chaos coefficients

Finite element based fatigue analysis of 6082 Aluminum alloy under random loading
Journal of Materials and Engineering Structures, 2018 Mechanical and structural components are subject in the most cases during their services to random loading. For this reason, it is necessary to reduce the complex history of these kinds of loading in a series of constant amplitude cycles.

Grey Wolf Optimization algorithm with random local optimal regulation and first-element dominance
Egyptian Informatics JournalDue to the classical Grey Wolf algorithm GWO does not consider the characteristics of the local information of individual in population, a novel local random optimization strategy is proposed to make up for the defect of GWO.

Generating Random Elements of Finite Distributive Lattices [PDF]
The Electronic Journal of Combinatorics, 1997 This survey article describes a method for choosing uniformly at random from any finite set whose objects can be viewed as constituting a distributive lattice. The method is based on ideas of the author and David Wilson for using "coupling from the past" to remove initialization bias from Monte Carlo randomization.

A Discrete-Element-Based Approach to Generate Random Parameters for Soil Fatigue Models
Journal of Marine Science and EngineeringThe structural reliability of bottom-fixed offshore wind turbines is generally influenced by the dispersion of and variability in soil properties, which affect their ultimate capacity, serviceability, and both the short- and long-term fatigue.

On Two Approaches to Slope Stability Reliability Assessments Using the Random Finite Element Method
Applied Sciences, 2019 The random finite element method has been increasingly used in the geotechnical community to investigate the influence of soil spatial variability and to bridge the gap between a traditional design and a reliability-based design. There are two approaches
