Application of Markov chain and entropy analysis to lithologic succession — an example from the early Permian Barakar Formation, Bellampalli coalfield, Andhra Pradesh, India

open access: closedJournal of Earth System Science, 2009
A statistical approach by a modified Markov process model and entropy function is used to prove that the early Permian Barakar Formation of the Bellampalli coalfield developed distinct cyclicities during deposition. From results, the transition path of lithological states typical for the Bellampalli basin is as: coarse to medium-grained sandstone ...

Double coset Markov chains

open access: yesForum of Mathematics, Sigma, 2023
Let G be a finite group. Let $H, K$ be subgroups of G and $H \backslash G / K$ the double coset space. If Q is a probability on G which is constant on conjugacy classes ( $Q(s^{-1} t s) = Q(t)$ ), then the random walk driven by Q on G ...

Fast reactions with non-interacting species in stochastic reaction networks

open access: yesMathematical Biosciences and Engineering, 2022
We consider stochastic reaction networks modeled by continuous-time Markov chains. Such reaction networks often contain many reactions, potentially occurring at different time scales, and have unknown parameters (kinetic rates, total amounts). This makes

On the Structure of Quantum Markov Chains on Cayley Trees Associated with Open Quantum Random Walks

open access: yesAxioms, 2023
Quantum Markov chains (QMCs) and open quantum random walks (OQRWs) represent different quantum extensions of the classical Markov chain framework. QMCs stand as a more profound layer within the realm of Markovian dynamics.

Probabilistic analysis and simulation of crack propagation in concrete pavements and surfaces

open access: yesScientific Reports, 2022
The surface of concrete pavement is susceptible to cracking. The propagation of a crack in a concrete structure may take the form of a one-dimensional line crack, a two-dimensional surface crack, or a three-dimensional volume crack.

A Wavelet-Based Computational Framework for a Block-Structured Markov Chain with a Continuous Phase Variable

open access: yesMathematics, 2023
We consider the computing issues of the steady probabilities for block-structured discrete-time Markov chains that are of upper-Hessenberg or lower-Hessenberg transition kernels with a continuous phase set.
