Basic reproductive number for a general hybrid epidemic model

open access: yesAdvances in Difference Equations, 2018
In this paper, a general hybrid epidemic model with multiple and non-periodic pulses in an environmental period is investigated. The definition and computation for the basic reproductive number R0 $R_{0}$ are established.

Satellite microwave assessment of Northern Hemisphere lake ice phenology from 2002 to 2015 [PDF]

open access: yesThe Cryosphere, 2017
A new automated method enabling consistent satellite assessment of seasonal lake ice phenology at 5 km resolution was developed for all lake pixels (water coverage  ≥  90 %) in the Northern Hemisphere using 36.5 GHz H-polarized brightness temperature (Tb)

The Numerical Simulation in Ballistics

open access: yesNonlinear Analysis: Modelling and Control, 2001
In this paper we examine the movement of the solid body thrown with some angle to the horizon (for example the shot mine). Such movement is described by non-linear system of equations. This system is being approximated by linear system, in segments. The experiment results have been approximated and the dependence of air resistance coefficient from mean

Analysis and optimal control of a Huanglongbing mathematical model with resistant vector

open access: yesInfectious Disease Modelling, 2021
Huanglongbing (HLB) is an incurable disease that affects citrus trees. To better understand the transmission of HLB, the mathematical model is developed to investigate the transmission dynamics of the disease between Asian citrus psyllid (ACP) and citrus

Generalized Finite Difference Method for Plate Bending Analysis of Functionally Graded Materials

open access: yesMathematics, 2020
In this paper, an easy-to-implement domain-type meshless method—the generalized finite difference method (GFDM)—is applied to simulate the bending behavior of functionally graded (FG) plates.

Numerical simulation of electrocardiograms

open access: yes, 2012
This chapter presents a concise overview of various mathematical and numerical problems raised by the simulation of electrocardiograms (ECGs). A model for the propagation of the electrical activation in the heart and in the torso is proposed. Some of its mathematical properties are analyzed.
