The corrosion resistance of a metal surface in contact with an aqueous medium can, in principle, be improved by imposing conditions that cause the otherwise chemically active surface to be passivated. In this work, several different control strategie

Simulation of deposit growth on a two-dimensional substrate was studied based on a new model that tracks individual cubic particles as they form a deposit structure. The present model is an extension of the classical ballistic deposition model. Effec

We describe two methods for modeling the thermal conductivity and temperature profile in a graded composite film. The film consists of a random binary composite, whose concentration varies in the direction perpendicular to the film surface, and a fix

The Portevin-Le Chatelier (PLC) effect, otherwise known as serrated yielding, repeated yielding, or jerky flow, has been a subject of investigation for many years. Modeling studies, and experiments have shown that the oscillatory PLC stress-strain dy

A new approach to obtaining information about a chaotic system is considered. The essence of the method lies in analysis of the statistics of repetitive experiments carried out under slightly varying initial conditions. This approach does not require

A method of linear feedback is shown to be applicable to the control or suppression of spontaneously occurring relaxation oscillations in a two-dimensional model for the passivation of a metal surface exposed to an aqueous medium. For the operating c

Some aspects of the steady-state behavior of a simple model for the dissociative chemisorption of a diatomic gas on a metal surface are considered. It is shown that within certain ranges of values for the rate parameters, multiple steady states exist

We describe methods for automating the control and tracking of states within or near a chaotic attractor. The methods are applied in a simulation using a recently developed model of thermal pulse combustion as the dynamical system. The controlled sta

Over the past 30 years or so, some fascinating new developments have taken place in a field that is now called “nonlinear science.” These developments have been of such magnitude that historian Alan Beyerchen concluded “There is every reason to
