Mathematical Modeling of Population Dynamics of Pollinators: A Survey [PDF]

open access: yesBiology
In this paper, we develop a systematic review of the existing literature on the mathematical modeling of several aspects of pollinators. We selected the MathSciNet and Wos databases and performed a search for the words “pollinator” and “mathematical ...

Bifurcations in a Plant-Pollinator Model with Multiple Delays

open access: yesJournal of Mathematics, 2023
The plant-pollinator model is a common model widely researched by scholars in population dynamics. In fact, its complex dynamical behaviors are universally and simply expressed as a class of delay differential-difference equations.

Modeling and Numerical Simulation of Semitensioned Mooring Line under Taut-Slack State

open access: yesShock and Vibration, 2023
In this paper, considering the mooring system can be taut-slack in the motion, the dynamic equations of the mooring system are derived by using the theory of large deformation.

A Ratio-Dependent Nonlinear Predator-Prey Model With Certain Dynamical Results

open access: yesIEEE Access, 2020
In order to see the dynamics of prey-predator interaction, differential or difference equations are frequently used for modeling of such interactions. In present manuscript, we explore some qualitative aspects of two-dimensional ratio-dependent predator ...

Accurately model the Kuramoto--Sivashinsky dynamics with holistic discretisation [PDF]

open access: yes, 2005
We analyse the nonlinear Kuramoto--Sivashinsky equation to develop accurate discretisations modeling its dynamics on coarse grids. The analysis is based upon centre manifold theory so we are assured that the discretisation accurately models the dynamics ...

Nonlinear Instability in Dissipative Finite Difference Schemes [PDF]

open access: yes, 1989
A unified analysis of reaction-diffusion equations and their finite difference representations is presented. The parallel treatment of the two problems shows clearly when and why the finite difference approximations break down. The approach used provides

Application of dynamical systems theory to the high angle of attack dynamics of the F-14 [PDF]

open access: yes, 1990
Dynamical systems theory has been used to study the nonlinear dynamics of the F-14. An eight degree of freedom model that does not include the control system present in operational F-14's has been analyzed.

Dynamical Analysis of SIR Epidemic Model with Nonlinear Pulse Vaccination and Lifelong Immunity

open access: yesDiscrete Dynamics in Nature and Society, 2015
SIR epidemic model with nonlinear pulse vaccination and lifelong immunity is proposed. Due to the limited medical resources, vaccine immunization rate is considered as a nonlinear saturation function.

On the Relationship between Equilibrium Bifurcations and Ideal MHD Instabilities for Line-Tied Coronal Loops [PDF]

open access: yes, 2009
For axisymmetric models for coronal loops the relationship between the bifurcation points of magnetohydrodynamic (MHD) equilibrium sequences and the points of linear ideal MHD instability is investigated imposing line-tied boundary conditions.
