Theoretical and numerical results for the nonlinear shallow water problem [PDF]

open access: yesSurveys in Mathematics and its Applications, 2023
In this paper, the nonlinear shallow water problem is studied analytically and numerically. This problem has been studied by different authors in the linear case; here we consider a nonlinear one with non constant coefficients.

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)

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.

Numerical modelling and simulation in sheet metal forming [PDF]

open access: yes, 2004
The application of numerical modelling and simulation in manufacturing technologies is looking back over about a 20–30 years history. In recent years, the role of modelling and simulation in engineering and in manufacturing industry has been continuously

Entropy splitting for high-order numerical simulation of compressible turbulence [PDF]

open access: yes, 2002
A stable high-order numerical scheme for direct numerical simulation (DNS) of shock-free compressible turbulence is presented. The method is applicable to general geometries. It contains no upwinding, artificial dissipation, or filtering.

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.
