A bioreactor integrated with an electrically driven membrane separation process (Reverse Electro-Enhanced Dialysis REED) is under investigation as potential technology for enhancing lactic acid bioproduction. In order reveal the operation of the integrated process to achieve a specific production goal, a methodology for goal driven control system development is expanded to handle periodically o...

Software development projects that utilize object-oriented techniques often adopt an iterative incremental process model. This process model uses many rapid passes over the fundamental development steps of analysis, design, and implementation to gradually refine the definition of the problem and evolve a solution to that problem. This model has proven useful but it is more difficult to visualiz...
