This article focuses on the numerical solution of a classical, irreversible Gray Scott reaction-diffusion system describing kinetics simple autocatalytic reaction in an unstirred ow reactor. A novel finite element scheme based B-spline collocation method is developed to solve this model. Before applying method, "strang splitting" idea especially popularized for PDEs...
BACKGROUND Available alfentanil pharmacokinetic (PK) sets for target-controlled infusion (TCI) were derived from populations with normal BMI. The performance and accuracy of the models devised by Maitre and colleagues and Scott and colleagues were evaluated in a population including morbidly obese patients. METHODS Alfentanil TCI using Maitre and colleagues' model was administered to 10 obese...
We give a complete classification of the phase portraits in Poincare´ disk for cubic polynomial systemsx˙=1−x−axy2,y˙=−by+axy2, R2 according with values its two parameters and b. These differential systems correspond to Gray-Scott model. Moreover we provide bifurcation diagram parameter plane (a,b) these systems.
Well-posedness in $ L_\infty of the nonlocal Gray-Scott model is studied for integrable kernels, along with stability semi-trivial spatially homogeneous steady state. In addition, it shown that solutions to system converge those classical diffusive limit.
