Abstract. Decomposing a system into views is relatively easy. The tricky part is putting the views back together without creating unexpected interference between the views. We argue that basing decomposition on the closed world approach helps in avoiding certain kinds of surprises when views are composed. The composition mechanism can statically enforce that the behaviors described by different...

this paper describes an optimal design for multivariable pi controller with a high gain structure for an irregular system by genetic algorithm. pi controllers with a high gain structure leads to the asymptotic decomposition of the fast and slow modes in the closed loop system that have unique characteristics. the slow modes are asymptotically uncontrollable and unobservable; therefore, they hav...

in this study, an intelligent system for sorting closed shell and open shell pistachio nuts, was designed and developed based on combined acoustic and artificial neural network (ann) techniques. the system included a microphone, pc, material handling equipment and an air reject pneumatic mechanism. the microphone, placed under the steel plate, received sound signals generated by the pistachio n...
