An Entropy Measure of Non-Stationary Processes
Entropy, 2014 Shannon’s source entropy formula is not appropriate to measure the uncertainty of non-stationary processes. In this paper, we propose a new entropy measure for non-stationary processes, which is greater than or equal to Shannon’s source entropy.

Stability criteria of the Vlasov equation and quasi-stationary states of the HMF model
, 2004 We perform a detailed study of the relaxation towards equilibrium in the Hamiltonian Mean-Field (HMF) model, a prototype for long-range interactions in $N$-particle dynamics.

Entropic Equilibria Selection of Stationary Extrema in Finite Populations
Entropy, 2018 We propose the entropy of random Markov trajectories originating and terminating at the same state as a measure of the stability of a state of a Markov process. These entropies can be computed in terms of the entropy rates and stationary distributions of

Strong Stationary Duality for Diffusion Processes
, 2015 We develop the theory of strong stationary duality for diffusion processes on compact intervals. We analytically derive the generator and boundary behavior of the dual process and recover a central tenet of the classical Markov chain theory in the ...

Strong approximation results for the empirical process of stationary sequences
, 2013 We prove a strong approximation result for the empirical process associated to a stationary sequence of real-valued random variables, under dependence conditions involving only indicators of half lines. This strong approximation result also holds for the

Optimal approximation model of autocorrelation function of digital image
Tongxin xuebao, 2011 Non-stationary stochastic signal was divided into piecewise stationary stochastic signal,and reflecting the sig-nal’s characteristics by autocorrelation function of the piecewise stationary stochastic signal.Generally,the autocorrela-tion function was ...

Introducing Plithogenic Stochastic Processes with an Application to Poisson Process [PDF]
Neutrosophic Sets and SystemsIn 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.

Modeling of Non-Stationary Mass Transfer Process in Groundwater
Nauka ta progres transportuPurpose. Infiltration of contaminated water and accidental spills of chemically hazardous substances into groundwater lead to the formation of large zones of man-made pollution in aquifers. Therefore, it is important to develop protection systems against
