Markov modeling and performance analysis of infectious diseases with asymptomatic patients

Mathematical Biosciences and Engineering, 2023
After over three years of COVID-19, it has become clear that infectious diseases are difficult to eradicate, and humans remain vulnerable under their influence in a long period.

Trend-Enabled Recommender System with Diversity Enhancer for Crop Recommendation

Agriculture
Achieving optimal agricultural yields and promoting sustainable farming relies on accurate crop recommendations. However, the applicability of many current systems is limited by their considerable computational requirements and dependence on ...

A Second Law for Open Markov Processes

, 2015
In this paper we define the notion of an open Markov process. An open Markov process is a generalization of an ordinary Markov process in which populations are allowed to flow in and out of the system at certain boundary states.

Investigation of a Markov Model for Computer System Security Threats

Моделирование и анализ информационных систем, 2017
In this work, a model for computer system security threats formulated in terms of Markov processes is investigated. In the framework of this model the functioning of the computer system is considered as a sequence of failures and recovery actions which ...

Semi-Markov Graph Dynamics [PDF]

, 2011
In this paper, we outline a model of graph (or network) dynamics based on two ingredients. The first ingredient is a Markov chain on the space of possible graphs. The second ingredient is a semi-Markov counting process of renewal type. The model consists

Comment on "Why quantum mechanics cannot be formulated as a Markov process" [PDF]

, 1996
In the paper with the above title, D. T. Gillespie [Phys. Rev. A 49, 1607, (1994)] claims that the theory of Markov stochastic processes cannot provide an adequate mathematical framework for quantum mechanics.

Jump Markov models and transition state theory: the Quasi-Stationary Distribution approach

, 2016
We are interested in the connection between a metastable continuous state space Markov process (satisfying e.g. the Langevin or overdamped Langevin equation) and a jump Markov process in a discrete state space.

Tornadoes and related damage costs: statistical modelling with a semi-Markov approach

Geomatics, Natural Hazards & Risk, 2016
We propose a statistical approach to modelling for predicting and simulating occurrences of tornadoes and accumulated cost distributions over a time interval.

Interaction of Markov processes

Advances in Mathematics, 1970
For a gentle approach to the problems connected with interacting Markov processes we review first what is known in the absence of interaction. For simplicity let S be a countable (or finite) set, and consider a countable (or finite if S is finite) collection of independent Markov processes on S,with common transition function P t (x,y), x, y ∈ S. It is

A Semi-Markov Modulated Interest Rate Model

, 2012
In this paper we propose a semi-Markov modulated model of interest rates. We assume that the switching process is a semi-Markov process with finite state space E and the modulated process is a diffusive process.
