PREDICTIVE GREY MARKOV CHAIN MODEL FOR PITTING CORROSION IN PIPLINES

open access: yesJixie qiangdu, 2016
Based on the Grey theory and Markov Chain theory,two prediction models were built,they are Grey Markov Chain prediction model based on absolute distribution( GMCAD) and Grey Markov Chain prediction model based on probability summation( GMCPS).

On Obtaining Sharp Bounds of the Rate of Convergence for a Class of Continuous-Time Markov Chains [PDF]

open access: yesarXiv, 2019
We study inhomogeneous continuous-time weakly ergodic Markov chains with a finite state space. We introduce the notion of a Markov chain with the regular structure of an infinitesimal matrix and study the sharp upper bounds on the rate of convergence for such class of Markov chains.

Aggregation of Markov chains

open access: yesStochastic Processes and their Applications, 1993
AbstractFor a collection of Markov chains the aggregated process, that is a process for which the transition rates are a mixture of the transition rates of the Markov chains in the collection, is introduced. A sufficient condition is given, called cross-balance, a generalization of global balance to a collection of processes, under which the ...

Living in the edge: demographic responses driven by density‐dependence and pulsed resources in a hibernating mammal

open access: yesEcography, EarlyView.
Populations at the edge of a species' distribution often encounter more challenging environmental conditions than those at the core, requiring unique adaptations and strategies. However, the demographic processes driving these populations remain poorly understood.

Bounds on Lifting Continuous Markov Chains to Speed Up Mixing [PDF]

open access: yesarXiv, 2016
It is often possible to speed up the mixing of a Markov chain $\{ X_{t} \}_{t \in \mathbb{N}}$ on a state space $\Omega$ by \textit{lifting}, that is, running a more efficient Markov chain $\{ \hat{X}_{t} \}_{t \in \mathbb{N}}$ on a larger state space $\hat{\Omega} \supset \Omega$ that projects to $\{ X_{t} \}_{t \in \mathbb{N}}$ in a certain sense.

Drivers of plant community composition and diversity in low Arctic western Greenland

open access: yesEcography, EarlyView.
The Arctic experiences rapid climate change, but our ability to predict how this will influence plant communities is hampered by a lack of data on the extent to which different species are associated with particular environmental conditions, how these conditions are interlinked, and how they will change in coming years.
