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.

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.

Investigation of $$\varXi _c^0$$ Ξ c 0 in a chiral quark model

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
Recently, three new states of $$\varXi _c^0$$ Ξ c 0 were observed in the invariant mass spectrum of $$\varLambda ^+_cK^-$$ Λ c + K - by LHCb collaboration.

Global convergence of RTLSQEP: A solver of regularized total least squares problems via quadratic eigenproblems

open access: yesMathematical Modelling and Analysis, 2008
The total least squares (TLS) method is a successful approach for linear problems if both the matrix and the right hand side are contaminated by some noise.

Numerical analysis of the shock train evolution in planar nozzles with throat length [PDF]

open access: yesFME Transactions, 2023
In the present investigation, the behavior of compressible flow in planar nozzles with throat length is analyzed to determine the flow velocity range and pressure fluctuations in the throat section.

Numerical Simulation of Baroclinic Jovian Vortices [PDF]

open access: yes, 1994
We examine the evolution of baroclinic vortices in a time-dependent, nonlinear numerical model of a Jovian atmosphere. The model uses a normal-mode expansion in the vertical, using the barotropic and first two baroclinic modes.
