The attractiveness of semi-active control systems mainly relies on their assumed "inherent stability", which makes them almost as reliable and fault-tolerant as passive control systems.
The final result, once the input parameters of the vibration control devices are properly designed, is an assembled structural system in which the glazing façade works as passive control system for the primary structure.
In past, many researchers have investigated the performance of various control techniques such as passive control viz.
Participants in Arm 3 will serve as passive controls and no acupressure plasters will be administered.
The applied tensile force, if needed, is to produce a net thrust below a critical level for buckling, and the boundary damping is introduced by a frictional force and a braking torque, which may be regarded as a passive control and depends linearly on the transverse and angular velocities of the controlled edge.
An optimization method is presented for design of an eccentrically braced frame (EBF), which is used as a passive control device for seismic design of building frames.
To dampen pressure fluctuations and to reduce noise, acoustic dampers are widely applied as a passive control means to stabilize combustion/engine systems.
A multi-storey shear planer frame coupled with a tuned mass damper (TMD) system as the passive control device is considered in the numerical simulation for controlling both displacement and acceleration subjected to base excitation.
The bone defects were divided for each time period into 7 groups, as follows: passive control group (CONT), active control groups (BOS), (HACS) and (COS) (no simvastatin), and groups (BOS + SIM), (HACS + SIM) (carrier and simvastatin combination).
Permeable coverings have been demonstrated to be an effective solution as a passive control method for indoor air conditions, especially in the summer season and, consequently, are an energy saving technique.
On the other hand, permeable coverings can be considered as a passive control method of indoor conditions and, consequently, have implications in the perception of indoor air quality, local thermal comfort, and energy savings.
