Dynamics of a Discrete Internet Congestion Control Model

Discrete Dynamics in Nature and Society, 2011
We consider a discrete Internet model with a single link accessed by a single source, which responds to congestion signals from the network. Firstly, the stability of the equilibria of the system is investigated by analyzing the characteristic equation ...

A Robust Rational Route to in a Simple Asset Pricing Model (revised March 2004) [PDF]

We investigate asset pricing dynamics in an adaptive evolutionary asset pricing model with fundamentalists, trend followers and a market maker. Agents can choose between a fundamentalist strategy at positive information cost or choose a trend following ...

Efficient computation of quasiperiodic oscillations in nonlinear systems with fast rotating parts [PDF]

, 2006
We present a numerical method for the investigation of quasiperiodic oscillations in applications modeled by systems of ordinary differential equations. We focus on systems with parts that have a significant rotational speed.

Bifurcations and chaos in a discrete SI epidemic model with fractional order

Advances in Difference Equations, 2018
In this study, a new discrete SI epidemic model is proposed and established from SI fractional-order epidemic model. The existence conditions, the stability of the equilibrium points and the occurrence of bifurcation are analyzed.

The Bifurcation of Two Invariant Closed Curves in a Discrete Model

Discrete Dynamics in Nature and Society, 2018
A discrete population model integrated using the forward Euler method is investigated. The qualitative bifurcation analysis indicates that the model exhibits rich dynamical behaviors including the existence of the equilibrium state, the flip bifurcation,

Market Mood, Adaptive Beliefs and Asset Price Dynamics [PDF]

Empirical evidence has suggested that, facing different trading strategies and complicated decision, the proportions of agents relying on particular strategies may stay at constant level or vary over time.

Deterministic randomness in a model of finance and growth [PDF]

Following the literature on growth, cycles and financial development, this paper develops an endogenous growth model where the source of endogenous business cycles relates to the allocation of credit between productive investment and consumption.

Food Security, Fertility Differentials and Land Degradation in Sub-Saharan Africa: A Dynamic Framework [PDF]

We study the impact of differential fertility levels for the food-insecure and food-secure population on the long-run values of the population distribution and resources in a descriptive model where the food security states are determined by a ...

Dynamics of a Conformable Fractional Order Generalized Richards Growth Model on Star Network with N=20 Nodes

Cumhuriyet Science Journal
In this study, we analyze dynamical behavior of the conformable fractional order Richards growth model. Before examining the analysis of the dynamical behavior of the fractional continuous time model, the model is reduced to the system of difference ...
