Therefore, a mathematical model of a frog population infected with chytridiomycosis was developed to investigate how the inoculation of Jl could reduce the impact of Bd on frogs. The model also illustrates the important role of temperature in the diseases epidemiology. The model simulation results ...
finite maximum agemodelling and simulationfinite volume approximationIMEX-WENOIn this article, we design a high-order implicit-explicit weighted non-oscillatory (IMEX-WENO) scheme for the solution of the population age density model with the nonlinear mortality rate as well as fertility rate. The ...

. As an illustration, we construct a two (space)-dimensional model of a copepod (Calanus finmarchicus) in the NE Atlantic, and demonstrate that its predictions correspond closely with those of an equivalent Lagrangian ensemble. 展开 关键词: population simulation spatial physiological heterogeneity ...
Estimability of natural mortality and other population parameters in alength-based model: Pandalus borealis in Kachemak Bay, Alaska Because stock-assessment models have become more complex, the question of estimability of population parameters is important. We conducted simulation-estim... CH Fu,TJ ...
A cell differentiation model consists of a system of ODE coupled to a PDE.A qualitative analysis, including stability and Hopf-bifurcation, is performed.A numerical analysis stresses the role of some important parameters on the stability and Hopf-bifurcation.The results can be used in some periodic...
Age-Structured Model Demographics A mathematical model which divides a population into different age classes in order to evaluate the effects of age-dependent infection, morbidity or mortality rates or age-specific vaccination schedules, and other factors. ...
Discontinuous Galerkin method for piecewise regular solutions to the nonlinear age-structured population model 来自 NCBI 喜欢 0 阅读量: 37 作者:Piotr Krzyanowski,D Wrzosek,D Wit 摘要: A discontinuous Galerkin approximation of the nonlinear Lotka–McKendrick equation is considered in the frequent case...
The rate of decrease in genetic variability and the number of generations required for fixation of a selectively neutral mutant gene were investigated for a geographically structured population. The population model analyzed is a linear and two-dimensional stepping-stone model of finite size. Genetic ...
We also check the performance of our WENO schemes for long time simulation. We simulate this model for 10 years (t=3650) and plot the total population (the integral of the density u over the length) in Fig. 5, for two different values of C in (33), namely C=2000 for the top pict...
