The structural control can provide the potential protection through passive and active control techniques. Structures with base isolations have been successfully implemented and proven effective in the vibration mitigation. To enhance the functionality of base isolations, a hybrid control system can be considered using a combination with active control devices. This research applies the hybrid ...

Spider dragline silk with its superlative tensile properties provides an ideal system to study the relationship between morphology and mechanical properties of a structural protein. Accordingly, we synthesized two hybrid multiblock copolymers by condensing poly(alanine) [(Ala)(5)] blocks of the structural proteins (spidroin MaSp1 and MaSp2) of spider dragline silk with different oligomers of is...

We address the issue of the quality of hybrid simulation, an experimental method used in earthquake engineering to examine the response of structural systems to dynamic excitation. After describing the typical sources and the effects of measurement and actuation errors, we present a reachability-based formulation of error propagation in hybrid simulation. This approach predicts possible (sets o...

in this paper, optimal design of hybrid solar-wind- diesel energy system with battery storage for reliable load in arsoon village in ardabil is presented. the village has 35 households that mean daily energy consumption is estimated 63.4 kwh. in this design optimization is implemented, considering loss of power supply probability (lpsp) index for reliable load providing, with minimum total cons...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...

Conversion of fossil fuels to electrical power is the most popular method of electrical power generation. Due to the depletion of fossil fuels and the increase in air pollution, the necessity of using high efficiency power generation systems is increasing. High temperature fuel cells, such as solid oxide fuel cells (SOFC) and molten carbonate fuel cells (MCFC), have high efficiency. According t...

Effective real-time testing of structural control devices relies on a hybrid test system that couples virtual structures under dynamic loading with physical sub-structures or devices in a dynamic test rig. The use of sensors and actuators in a closed-loop feedback system maintains the dynamic equilibrium of the overall system comprising the physical test article and virtual modelled structure. ...
