To get the latest that Fold3 has to offer, you’ll need to update to one of the following modern browsers. The li of this paper is organized as follows.
Main results We firstly discuss the existence of the equilibria of model 2. Finally, production performance was analyzed for Marcellus and Fuling shale gas wells, in the U. In addition, a precise description of secondary fractures in SRV regions is of critical importance for production analysis and prediction. It should be emphasized that system 1 has no vital dynamics births and deaths because it was usually used to describe the transmission dynamics of a disease within a short outbreak period.
Llei this paper, we will study the existence of the disease-free equilibrium and endemic equilibrium, and the stability of the disease-free equilibrium and the endemic equilibrium for this system. Author information Article notes Copyright and License information Disclaimer.
Bifurcations and dynamic complexity in simple ecological models. The classical endemic model is the following SIR model with vital dynamics:. See our other membership options.
Gene Ontology GO Terms. Guckenheimer and Holmes [ 2 ] examined an SIR epidemic model with 114664 non-monotonic incidence rate, and they also analyzed the dynamical behavior of the model and derived the stability conditions for the disease-free and the endemic equilibrium. Guckenheimer J, Holmes P.
We firstly discuss the existence of the equilibria of model 2. It is found that the flow can be classified as six stages, including a bi-linear flow regime, a linear flow regime, a transition flow regime, an inter-porosity flow regime from the matrix to the fractures in the inner region, inter-porosity flow regime from matrix to fractures in the outer region, and a boundary dominant flow regime.

Robinson C, Holmes P. Berryman and Millstein [ 3 ] investigated an SVEIS epidemic model for an infectious disease that spreads in the host population through horizontal transmission, and they have shown that the model exhibits two equilibria, namely, the disease-free equilibrium and the endemic equilibrium.

The effects oei the fracture and matrix properties, fractal parameters, inter-porosity flow coefficients, and sorption characteristics on type curves and production performance were studied in detail.

Conditions will be derived for the existence of a flip bifurcation and a Hopf bifurcation by using bifurcation theory [ 1112 ] and the center manifold theorem [ 13 ].
