Kolmogorov's criterion states that the necessary and sufficient condition for a process to be reversible is that the product of transition rates around a closed loop must be the same in both directions. A stationary random process X(t) is applied to the input of a system for which h(t) = u(t) t 2 e (-8t). If E[X(t)] = 2, the mean value of the system’s response Y(t) is A. Intuitively, a random process {X(t), t ∈ J } is stationary if its statistical properties do not change by time.

Consider following statements: (i) X (t) is first order stationary. (ii) X (t) has total average power of 36 W. (iii) X (t) is a wide sense stationary.

Thus for a purely non-deterministic process we can approximate it with an ARMA process, the most popular time series model. Thus for a weakly stationary process we can use ARMA models. Elution :- is a process of removing adsorbed material from stationary phase by the movement of mobile phase. Eluent :- It is a solvent that used for separation of absorbed material from stationary phase. Eluate :- is a liquid solution that is a result from Elution. Chromatogram :- It is a graphical represention of Chromatography. The stationary distribution gives information about the stability of a random process and, in certain cases, describes the limiting behavior of the Markov chain.

A trend stationary process is not strictly stationary, but can easily be transformed into a stationary process by removing the underlying trend, which is solely a function of time. Similarly, processes with one or more unit roots can be made stationary through differencing. Intuitively, a random process {X(t), t ∈ J } is stationary if its statistical properties do not change by time. For example, for a stationary process, X(t) and X(t + Δ) have the same probability distributions. In particular, we have FX ( t) (x) = FX ( t + Δ) (x), for all t, t + Δ ∈ J. A stationary random process X(t) is applied to the input of a system for which h(t) = u(t) t 2 e (-8t). If E[X(t)] = 2, the mean value of the system’s response Y(t) is A. 1.
