The management of coal ash in utility boilers continues to be one of the most important fuel property considerations in the design and operation of commercial boilers. The behavior of mineral matter in coal can significantly influence furnace sizing, heat transfer surface placement, and convection pass tube spacing. Ironically, many of the more reactive, low rank U. S. coals must have larger fu...

Statecharts are a tool to model the reactive behavior of an object or system. Statecharts can be extended to execute on separate machines and coordinate with each other to achieve complex reactive behavior. We propose using a framework of classes to take statechart diagrams and make them executable on separate machines to handle pervasive computing concerns.
