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 ...

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.

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 ...

Universal tradeoff relation between speed, uncertainty, and dissipation in nonequilibrium stationary states

open access: yesSciPost Physics, 2022
We derive universal thermodynamic inequalities that bound from below the moments of first-passage times of stochastic currents in nonequilibrium stationary states of Markov jump processes in the limit where the thresholds that define the first ...

On Markovian cocycle perturbations in classical and quantum probability

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
We introduce Markovian cocycle perturbations of the groups of transformations associated with classical and quantum stochastic processes with stationary increments, which are characterized by a localization of the perturbation to the algebra of events ...

Thermodynamics and Fluctuations Far From Equilibrium

open access: yesEntropy, 2010
We review a coherent mesoscopic presentation of thermodynamics and fluctuations far from and near equilibrium, applicable to chemical reactions, energy transfer and transport processes, and electrochemical systems.

Stochastic metrology and the empirical distribution

open access: yesPhysical Review Research, 2023
We study the problem of parameter estimation in time series stemming from general stochastic processes, where the outcomes may exhibit arbitrary temporal correlations.
