Network Inoculation: Heteroclinics and phase transitions in an epidemic model [PDF]

open access: yes, 2016
In epidemiological modelling, dynamics on networks, and in particular adaptive and heterogeneous networks have recently received much interest. Here we present a detailed analysis of a previously proposed model that combines heterogeneity in the ...

Relaxation to Fixed Points in the Logistic and Cubic Maps: Analytical and Numerical Investigation

open access: yesEntropy, 2013
Convergence to a period one fixed point is investigated for both logistic and cubic maps. For the logistic map the relaxation to the fixed point is considered near a transcritical bifurcation while for the cubic map it is near a pitchfork bifurcation. We

THE ROLE OF COST OF LOAN IN BANKING LOAN DYNAMICS: BIFURCATION AND CHAOS ANALYSIS

open access: yesBarekeng, 2022
The gradient adjustment process is used to create a dynamic model of banking loan. The sign of the loan’s marginal profit determines how much money will be loaned in the future.

Adiabatic reduction near a bifurcation in stochastically modulated systems

open access: yes, 1997
We re-examine the procedure of adiabatic elimination of fast relaxing variables near a bifurcation point when some of the parameters of the system are stochastically modulated.

Stabilizing unstable periodic orbits in the Lorenz equations using time-delayed feedback control

open access: yes, 2007
For many years it was believed that an unstable periodic orbit with an odd number of real Floquet multipliers greater than unity cannot be stabilized by the time-delayed feedback control mechanism of Pyragus.

A food chain ecoepidemic model: infection at the bottom trophic level [PDF]

open access: yes, 2014
In this paper we consider a three level food web subject to a disease affecting the bottom prey. The resulting dynamics is much richer with respect to the purely demographic model, in that it contains more transcritical bifurcations, gluing together the ...

The Local Bifurcation of Food web Prey-Predator Model involving fear and anti-Predator behavior

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences
     In this paper, the conditions under which the occurrence of the local bifurcation (such as saddle-node (SN), transcritical (TC), and pitchfork (PT)) of all stable points of a food web model have been investigated.

Population Dynamic Study of Prey-Predator Interactions with Weak Allee Effect, Fear Effect, and Delay

open access: yesJournal of Mathematics, 2022
In this study, a predator-prey model with the Allee effect and fear effect is established. We use the comparison principle to prove boundedness. The zero equilibrium point and nonzero equilibrium point of the model are calculated, and the local stability

Food Quality in Producer-Grazer Models: A Generalized Analysis

open access: yes, 2010
Stoichiometric constraints play a role in the dynamics of natural populations, but are not explicitly considered in most mathematical models. Recent theoretical works suggest that these constraints can have a significant impact and should not be ...

ANALYSIS OF BANKING DEPOSIT COST IN THE DYNAMICS OF LOAN: BIFURCATION AND CHAOS PERSPECTIVES

open access: yesBarekeng, 2022
A dynamic model of banking loan based on the gradient adjustment process is presented. The amount of loan that will be channeled in the future depends on the sign of the marginal profit of loan. In this paper, we study the deposit cost in the dynamics of
