Finite Element Analysis of the Ramberg-Osgood Bar
In this work, we present a priori error estimates of finite element approximations of the solution for the equilibrium equation of an axially loaded Ramberg-Osgood bar. The existence and uniqueness… Expand
On the numerical solution of perturbed bifurcation problems
Some numerical schemes, baseduponNewton's and chord methods, for thecomputations of the perturbed bifurcation points as well as the solution curves through them, are presented. The "initial" guesses… Expand
Finite difference solutions of the heat equation in a molten polymer flowing in a circular tube
We present the mathematical equations that govern heat transfer in a polymer melt flowing in a circular tube with constant ambient temperature, taking into account the viscous dissipation effects.… Expand
A Lumped-Parameter Model for Nonlinear Waves in Graphene
A lumped-parameter nonlinear spring-mass model which takes into account the third-order elastic stiffness constant is considered for modeling the free and forced axial vibrations of a graphene sheet… Expand
On the shooting method for a class of two-point singular nonlinear boundary value problems
This paper is concerned with the application of the shooting method to a class of two-point singular nonlinear boundary value problems. An explicit fourth order single-step method for the solution of… Expand

As induction agents for cardioanesthesia, sufentanil (S) and fentanyl (F) are usually employed in combination with nondepolarizing muscle relaxants. We investigated potential interactions of these… Expand
A Note on the Proof of the Perron-Frobenius Theorem
This paper provides a simple proof for the Perron-Frobenius theorem concerned with positive matrices using a homotopy technique. By analyzing the behaviour of the eigenvalues of a family of positive… Expand
An initial value problem method for a class of two-point weakly singular nonlinear boundary value problems
We present an iterative method, based on the solution of singular initial value problems, for the numerical integration of a class of two-point weakly singular nonlinear boundary value problems.
