A Two-Stage Mutation Stochastic Model of Carcinogenesis Driven by a Two Level Random Environment [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2020
In this paper, we present a two-stage stochastic model of carcinogenesis in a two level random environment. The random environment switches between two levels, say, 1 and 2 alternately.

Analysis of a Stochastic Inventory Model on Random Environment with Two Classes of Suppliers and Impulse Customers

open access: yesMathematics, 2022
This paper explores the random environment with two classes of suppliers and impulse customers. The system’s greatest inventory size is S, and it has an infinitely large orbit.

Management and Optimal Control Algorithm for Electric Vehicle Charging in Random Environment

open access: yesShanghai Jiaotong Daxue xuebao, 2023
With the increasing scale of electric vehicles (EVs), the adaptive management of its charging behavior becomes an urgent problem to be solved. From the point of view of charging service provider, an online management algorithm for EV charging is proposed

Random Walks in Cooling Random Environments [PDF]

open access: yes, 2019
We propose a model of a one-dimensional random walk in dynamic random environment that interpolates between two classical settings: (I) the random environment is sampled at time zero only; (II) the random environment is resampled at every unit of time. In our model the random environment is resampled along an increasing sequence of deterministic times.

Random walk in changing environment [PDF]

open access: yesStochastic Processes and their Applications, 2020
In this paper we introduce the notion of Random Walk in Changing Environment - a random walk in which each step is performed in a different graph on the same set of vertices, or more generally, a weighted random walk on the same vertex and edge sets but with different (possibly 0) weights in each step.

A Two-Stage Mutation Stochastic Model of Carcinogenesis Driven by a Three Level Environmental Process [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2020
A two-mutation model of carcinogenesis which evolves under the influence of three level random environment on the production process is formulated and analyzed.

Study of crushing of grains of limestone under the effect of cyclic loading with the fractal dimension

open access: yesJournal of Building Materials and Structures, 2018
The grains can be of very diverse nature (size, shape, mineralogy, etc), indeed even if each grain is a fairly simple object, the set of grains is a very complex system in which the geometrical and physical properties of the grains, their forces and ...

The MAP/PH/N/∞ Queueing-Inventory System With Demands From a Random Environment

open access: yesIEEE Access, 2022
This study investigates a multi-server queueing-inventory system in a random environment. The system has an unlimited waiting space and an inventory capacity of $S$ units.

On comparing configuration graphs robustness in a random environment

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
We consider configuration graphs with vertex degrees distributed independently according to the power law, with a truncated parameter τ normally distributed on the interval (a, b).
