A Model for Reinfections and the Transition of Epidemics
Viruses, 2023 Reinfections of infected individuals during a viral epidemic contribute to the continuation of the infection for longer periods of time. In an epidemic, contagion starts with an infection wave, initially growing exponentially fast until it reaches a ...

Analytic Combinatorics of the Mabinogion Urn [PDF]
Discrete Mathematics & Theoretical Computer Science, 2008 The Mabinogion urn is a simple model of the spread of influences amongst versatile populations. It corresponds to a non-standard urn with balls of two colours: each time a ball is drawn, it causes a ball of the other kind to switch its colour.

Sequential Interval Reliability for Discrete-Time Homogeneous Semi-Markov Repairable Systems
Mathematics, 2021 In this paper, a new reliability measure, named sequential interval reliability, is introduced for homogeneous semi-Markov repairable systems in discrete time.

Asymptotic analysis of the steady advection-diffusion problem in axial domains [PDF]
Opuscula Mathematica, 2023 We present the asymptotic analysis of the steady advection-diffusion equation in a thin tube. The problem is modeled in a mixed-type variational formulation, in order to separate the phenomenon in the axial direction and a transverse one.

Mathematical Model of the Reliability Analysis of a Heterogeneous Duplicate Data Transmission System
Современные информационные технологии и IT-образование, 2020 In this work, we consider the mathematical model of the repaired data transmission system as a model of a closed heterogeneous cold standby system with one repair device with an arbitrary number of data sources with an exponential distribution function ...

Quicksort algorithm again revisited [PDF]
Discrete Mathematics & Theoretical Computer Science, 1999 We consider the standard Quicksort algorithm that sorts n distinct keys with all possible n! orderings of keys being equally likely. Equivalently, we analyze the total path length L(n) in a randomly built \emphbinary search tree.

Cruising speed of a cylindrical wing performing small translational-rotational oscillations
Учёные записки Казанского университета: Серия Физико-математические науки, 2022 This work considers the propulsive motion of a flapping wing of a circular cross section. The problem of harmonic translational-rotational oscillations of the wing with an arbitrary phase shift in a viscous incompressible fluid, the motion of which is ...

A note on the MHD flow in a porous channel [PDF]
Theoretical and Applied Mechanics, 2022 In this paper we study the flow of a viscous incompressible conducting fluid through a corrugated channel filled with a porous medium. The fluid flow in the channel is under the action of the transverse magnetic field and driven by the pressure drop ...

, 2021 In this paper we study the asymptotic behaviour of a family of elliptic systems, as far as the existence of solutions is concerned. We give a special attention to the asymptotic behaviour of W and V as ε goes to zero in the system −ε2Δu+W(x)u=Qu(u,v)in ...

Scaling Limits of a Tandem Queue with Two Infinite Orbits
Mathematics, 2023 This paper considers a tandem queueing network with a Poisson arrival process of incoming calls, two servers, and two infinite orbits by the method of asymptotic analysis.
