Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]
Computer Methods in Biomechanics and Biomedical Engineering, 2010 The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Electronic Journal of Qualitative Theory of Differential Equations, 2002 The method of quasilinearization for nonlinear impulsive differential equations with linear boundary conditions is studied. The boundary conditions include periodic boundary conditions. It is proved the convergence is quadratic.

Solvability of a fourth order boundary value problem with periodic boundary conditions
International Journal of Mathematics and Mathematical Sciences, 1988 Fourth order boundary value problems arise in the study of the equilibrium of an elastaic beam under an external load. The author earlier investigated the existence and uniqueness of the solutions of the nonlinear analogues of fourth order boundary value

Perturbations of periodic boundary conditions
SIAM Journal on Mathematical Analysis, 1982 We consider perturbations of the problem (*) \(-x''+bx=\lambda ax,x(0)- x(1)=0, x'(0)-x'(1)=0\) both by changes of the boundary conditions and by addition of nonlinear terms. We assume that at \(\lambda =\lambda_ 0\) there are two linearly independent solutions of (*) and that a is bounded away from zero. When only the boundary conditions are perturbed
