The method of upper-lower solutions for continuous parabolic equations is extended to some finite difference system for numerical solutions. The idea of this method is that by using the upper or lower ...

This is a preview. Log in through your library . Abstract Boundary perturbation methods, in which the deviation of the problem geometry from a simple one is taken as the small quantity, have received ...

Fuzzy Fredholm integral equations represent a class of mathematical problems in which uncertainty is incorporated directly into the model via fuzzy numbers. These equations extend the classical ...

Find the forces on the object. Find the new momentum (based on the force and the small time interval) Find the new position (based on the velocity and time interval). Simple. And it even works most of ...

Northwestern University researchers have developed a more efficient and stable method to conduct electrocatalytic reactions. The technique, which fluidizes catalyst particles in electrolyte instead of ...
