Markov model

A model used in decision analysis for evaluating potential outcomes of a disease process, which are defined as specific health states, transitions among which are modelled iteratively. In standard decision tree analysis, a patient moves through states—for example, from not treated, to treated, to final outcome; in a Markov process, a patient moves between states (e.g., backwards and forward between continuous ambulatory peritoneal dialysis and haemodialysis). Some states cannot be left once entered (so-called “absorbing states”), including death.

We model the [Ca.sup.2+] channel by using the 3-state Markov chain of Figure 1(a), where C corresponds to the closed state, O to the open state, and B to the inactivated (blocked) state of the calcium channel [11].
Markov chains are required to be ergodic; therefore it can be ensured that the leader has directed paths to all followers in [G.sup.u].

The probability [p.sub.n] that the discrete-time Markov chain defined in Section 2.1, starting from n, will hit N before 1 is given by (40) if a [not equal to] 1/2.

In this section, we present the combinatorial characterization of output functions of Markov chains which are asymptotically independent and of Markov chains with output functions with a singular variance-covariance matrix.
Markov Chains are based on two considerations, the first is the supposition that lithology at any point n depends upon the lithology of the proceeding point n-1.
For the single latent dual redundant system we can ignore the discrete repair assumption (repair only on ground) and model the system with a continuous time Markov chain model.
In this section, we provide a discrete-time Markov chain model for the analysis of the CSMA/CA-based IEEE 802.15.6 MAC.

Let {[N.sup.(1).sub.1], i [member of] the N}, {[N.sup.(2).sub.i], i [member of] N} be the corresponding embedded Markov chains as well as their stationary distributions {[[pi].sup.(1).sub.n]}, {[[pi].sup.(2).sub.n]}, respectively.
