Extreme Characteristics of a Stochastic Non-Stationary Duffing Oscillator

open access: yesEngineering Proceedings, 2023
Unexpected responses in dynamic systems can lead to catastrophic failures. Without full knowledge of the system, it is impossible to know whether all of the dynamics have been captured or considered. Furthermore, a large number of Monte Carlo simulations

Non-Stationary Stochastic Global Optimization Algorithms

open access: yesAlgorithms, 2022
Studying the theoretical properties of optimization algorithms such as genetic algorithms and evolutionary strategies allows us to determine when they are suitable for solving a particular type of optimization problem. Such a study consists of three main

Introducing Plithogenic Stochastic Processes with an Application to Poisson Process [PDF]

open access: yesNeutrosophic Sets and Systems
In this paper, we study and define the mathematical form of plithogenic stochastic processes PSP based on set of three classic stochastic processes. This new definition is a generalization of neutrosophic stochastic process.

ON THE QHASI CLASS AND ITS EXTENSION TO SOME GAUSSIAN SHEETS

open access: yesInternational Journal for Computational Civil and Structural Engineering, 2022
Introduced in 2018 the generalized bifractional Brownian motion is considered as an element of the quasi-helix with approximately stationary increment class of real centered Gaussian processes conditioning by parameters.

White noise based stochastic calculus associated with a class of Gaussian processes [PDF]

open access: yesOpuscula Mathematica, 2012
Using the white noise space setting, we define and study stochastic integrals with respect to a class of stationary increment Gaussian processes. We focus mainly on continuous functions with values in the Kondratiev space of stochastic distributions ...

The Stationary Behaviour of Fluid Limits of Reversible Processes is Concentrated on Stationary Points [PDF]

open access: yes, 2012
Assume that a stochastic processes can be approximated, when some scale parameter gets large, by a fluid limit (also called "mean field limit", or "hydrodynamic limit").

Simulation of Nonstationary and Nonhomogeneous Wind Velocity Field by Using Frequency–Wavenumber Spectrum

open access: yesFrontiers in Built Environment, 2021
The time history analysis is used to estimate the peak responses of structures subjected to stationary and nonstationary winds. The time histories of the fluctuating wind processes at multiple points can be simulated based on the spectral representation ...

Simulating Non-Gaussian Stationary Stochastic Processes by Translation Model

open access: yesIEEE Access, 2019
The translation model is a useful tool to characterize stochastic processes or random fields. In this paper, this model is extended to simulate stochastic processes with discrete marginal distributions.

Analyzing long-term correlated stochastic processes by means of recurrence networks: Potentials and pitfalls [PDF]

open access: yes, 2014
Long-range correlated processes are ubiquitous, ranging from climate variables to financial time series. One paradigmatic example for such processes is fractional Brownian motion (fBm).

Stochastic transient analysis of thermal stresses in solids by explicit time-domain method

open access: yesTheoretical and Applied Mechanics Letters, 2019
Stochastic heat conduction and thermal stress analysis of structures has received considerable attention in recent years. The propagation of uncertain thermal environments will lead to stochastic variations in temperature fields and thermal stresses ...
