On the Marangoni and gravity flow in an inclined channel of an arbitrary section
Abstract In this paper we use a lubrication approximation in order to investigate the flow of a thin layer of…
On the Marangoni flow on an inclined plane
Abstract We consider the flow of a uniform thin layer (rivulet, trickle) of viscous fluid down an inclined plane driven…
The numerical approximation to positive solution for some reaction-diffusion problems
Abstract A one-dimensional reaction-diffusion problem, with the reaction term of the form \(u^{p}\), \(p>1\) is considered. For \(p=3\), we deduce…
On the bifurcation and variational approximation of the positive solution of a nonlinear reaction-diffusion problem
Abstract We consider a nonlinear, second-order, two-point boundary value problem that models some reaction-diffusion processes. When the reaction term has…
A unified treatment of boundary layer and lubrication approximations in viscous fluid mechanics
Abstract It is a matter of every day experience to find the boundary layer and lubrication approximations exposed as if…
Random Walkers Cellular Automata for Diffusion Processes
Abstract Smooth concentration fields and balance equations for systems of random walkers are obtained by using the coarsegrained space‐time averaging…
On the Misra-Prigogine-Courbage theory of irreversibility 2. The existence of the nonunitary similarity
Abstract Stochastic processes and dynamical systems in measure spaces are defined as classes of random variables in the Doob sense.…
Derivation of one-dimensional hydrodynamic model for stock price evolution
Abstract It was proved that balance equations for systems with corpuscular structure can be derived if a kinematic description by…
Perturbed-Steffensen-Aitken projection methods for solving equations with nondifferentiable operators
Abstract We use perturbed Steffensen-Aitken methods to approximate a locally unique solution of an operator equation in a Banach space. Using…
On the approximate solutions of implicit functions using the Steffensen method
Abstract We use inexact Steffensen-Aitken-type methods to approximate implicit functions in a Banach space. Using a projection operator our equation reduces to…
