Energy based seismic design getting attraction since it accounts for all structural (hysteretic behavior of members), earthquake (amplitude, duration and frequency content) soil (bearing capacity, characteristics. To develop an efficient energy procedure, accurate determination the fundamental periods deposits is crucial. Hence, several analytical, numerical approximate methods were suggested i...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...
