Dynamics of a ring of three coupled relaxation oscillators
Coupled oscillators Nonlinear vibrations Bifurcations Perturbations
2015/8/27
he dynamics of a ring of three identical relaxation oscillators is shown to exhibit a variety of periodic motions, including clockwise and counter-clockwise wave-like modes, and a synchronous mode in ...
Evolutionary dynamics of a system with periodic coefficients
Replicator equation Parametric excitation Evolutionary dynamics
2015/8/27
We investigate a problem in evolutionary game theory based on replicator equations with periodic coefficients. This approach toevolution combines classical game theory withdiffer-ential equations. The...
On the dynamics of a thin elastica
Elastica Non-local modes DPM Method of direct partition of motion
2015/8/27
We revisit the two degrees of freedom model of the thin elastica presented by Cusumano and Moon(1995) [3]. We observe that for the corresponding experimental system (Cusumano and Moon, 1995[3]), the r...
Coupled Parametrically Driven Modes in Synchrotron Dynamics
Parametric Coupled Oscillators Mathieu Synchrotron
2015/8/26
This work concerns the dynamics of a type of particle accelerator called a synchrotron, in which particles are made to move in nearly circular orbits of large radius. The stability of the transverse m...
Hopf Bifurcations in Two-Strategy Delayed Replicator Dynamics
Replicator Delay Hopf bifurcation Limit cycle Lindstedt
2015/8/26
We investigate the dynamics of two-strategy replicator equations in which the fitness of each strategy is a function of the population frequencies delayed by a time interval T. We analyze two models: ...
ANALYSIS AND IMPLEMENTATION OF THE GAS-KINETIC BGK SCHEME FOR COMPUTATIONAL GAS DYNAMICS
gas evolution model gas-kinetic BGK schemes entropy condition gas-kinetic Lax±Wendroff ˉux
2015/7/1
Gas-kinetic schemes based on the BGK model are proposed as an alternative evolution model which can cure some of the limitations of current Riemann solvers. To analyse the schemes, simple advection eq...

Numerical Schemes Gas Dynamics Discrete Shock Structure
2015/7/1
The effect of artificial diffusion on discrete shock structures is examined for a family of schemes which includes scalar diffusion, convective upwind and split pressure (CUSP)...
Analysis and Design of Numerical Schemes for Gas Dynamics 1 Artificial Diffusion, Upwind Biasing, Limiters and Their Effect on Accuracy and Multigrid Convergence
Design of Numerical Schemes Gas Dynamics usion Upwind Biasing Limiters Accuracy Multigrid Convergence
2015/7/1
The theory of non-oscillatory scalar schemes is developed in this paper in terms of the local extremum diminishing (LED) principle that maxima should not increase and minima should not decrease. This ...
In order to develop a performance baseline for future cooperative, dual aircraft operations, an experimental evaluation of pilot-in-the-loop, dual aircraft system dynamics in visual meteorological con...
