multi frequency vibrations of a system of two isotropic circular plates interconnected by a rolling visco-elastic layer that has nonlinear characteristics are considered. the system with two circular plates and interconnecting discrete continually distributed rolling visco nonlinear elastic rheological elements presents the model of hybrid nonlinear system. the analytical solutions of first asy...

We propose a distributed dynamic frequency allocation algorithm that achieves performance close to that of a centralized optimal algorithm. In our network model, nodes are grouped into a number of clusters. Each cluster chooses its transmission frequency band based on its knowledge of the interference that it experiences. The convergence of the proposed distributed algorithm to a sub-optimal fr...

The AECOO industry is highly fragmented; therefore, efficient information sharing and exchange between various players are evidently needed. Furthermore, the information about facility components should be managed throughout the lifecycle and be easily accessible for all players in the AECOO industry. BIM is emerging as a method of creating, sharing, exchanging and managing the information thro...

In this work, we consider output-feedback distributed model predictive control (DMPC) based on state estimation with bounded process disturbances and output measurement noise. Specifically, a scheme observer-enhanced moving horizon (DMHE) is considered for purposes. The DMHE ensures that the estimates of system reach small neighborhood actual values quickly then maintain within neighborhood. Th...

abstract irregular extraction from agricultural wells around parishan lake, moreover fall of groundwater surface and water salty, would affect the level of lake water and move lake water into wells. in this study we have evaluated the externalities of extraction from agricultural wells around the lake. therefore feedback effect is considered between agricultural activity around the lake and lev...
