Dynamic Analysis of an SICR Hepatitis C Infection Model with Stochastic Effects

open access: yesJournal of Harbin University of Science and Technology, 2023
In order to study the influence of uncertain factors on hepatitis C in reality, a randomized SICR hepatitis C model with acute and chronic infection was considered.

Analysis of a stochastic SIR model with fractional Brownian motion [PDF]

open access: yes, 2018
In this article, a stochastic version of a SIR nonautonomous model previously introduced in Kloeden and Kozyakin (2011) is considered. The noise considered is a fractional Brownian motion which satisfies the property of long range memory, which roughly ...

Role of Media and Effects of Infodemics and Escapes in the Spatial Spread of Epidemics: A Stochastic Multi-Region Model with Optimal Control Approach

open access: yesMathematics, 2019
Mass vaccination campaigns play major roles in the war against epidemics. Such prevention strategies cannot always reach their goals significantly without the help of media and awareness campaigns used to prevent contacts between susceptible and infected

Revisiting Online Algorithms: A Survey of Set Cover Solutions Beyond Competitive Analysis

open access: yesIEEE Access
Online algorithms are crucial for real-time decision-making and adaptability across diverse fields, such as operations research, computer science, and combinatorics. These algorithms handle data incrementally and make decisions without prior knowledge of

Simple Degree-of-Freedom Modeling of the Random Fluctuation Arising in Human–Bicycle Balance

open access: yesApplied Sciences, 2019
In this study, we propose a new simple degree-of-freedom fluctuation model that accurately reproduces the probability density functions (PDFs) of human−bicycle balance motions as simply as possible.

A step towards holistic discretisation of stochastic partial differential equations [PDF]

open access: yes, 2003
The long term aim is to use modern dynamical systems theory to derive discretisations of noisy, dissipative partial differential equations. As a first step we here consider a small domain and apply stochastic centre manifold techniques to derive a model.

A stochastic model for the dynamics of electromagnetic waves connected to each other on the mirror

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
The paper develops stochastic differential equations serving as the basis for derivation of master equations for microcavity photons pumped with either classic or quantized contracted fields.

Stochastic modelling [PDF]

open access: yesProceedings of the workshop on Data-driven methods in machine translation -, 2001
This paper gives an overview of the stochastic modelling approach to machine translation. Starting with the Bayes decision rule as in pattern classification and speech recognition, we show how the resulting system architecture can be structured into three parts: the language model probability, the string translation model probability and the search ...

Aviation industry stochastic model based on big data concept

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2018
Modern aviation industry is a complex large-scale system that includes designing, testing, production, operation, maintains services, etc. Thus, it seems reasonable to provide information logistical support throughout the life cycle of single processes ...
