A system for creating an agreement and tracking compliance with terms of an agreement between a seller and a purchaser for the sale of loans includes deal management logic and a rules processor. As the water travels through the mechanical filter before reaching the biological filter, the water has been processed and cleaned by the mechanical filter, preventing the mechanically filtered elements from being disposed on the biological filters, to improve the reliability of the biological filter. In an illustrative embodiment, the balanced BST is built by identifying a central pointer at a midpoint of the pointer list, a left range of pointers before the midpoint, and a right range of pointers after the midpoint. The method further comprises comparing the first economic value with the second economic value to identify the operating mode that provides the higher economic value, and operating the turbine facility in the identified operating mode. The MEMS element is mounted on the ASIC element, so that there is a gap between the micromechanical structure and the surface of the ASIC element.
