This is interesting in view of the documented role of cytokinin in nodule initiation and strongly suggests that the levels of active cytokinins are actively controlled in the nodule apex.
To ensure persistent excitation of the system to achieve convergence of estimated parameters, both axes of the device are actively controlled by an appropriately designed adaptive controller.
It is levitated by two HMBs at both ends in five-degree-of-freedom with proportional-integral-derivative (PID) controllers; among which four radial directions are actively controlled and one axial direction is passively controlled.
The currents in the battery and the supercapacitor are actively controlled by two bidirectional buck boost converters.
By this definition, it is physically reasonable comparing the quality of several design candidates since all candidates are actively controlled with the same energy consumption.
In this context, the trajectory generation techniques available to date have been designed for a servicing satellite, the attitude and position of which are actively controlled.
The structure is comprised of pneumatically inflated sections that are actively controlled and stabilized to balance external disturbances and support the structure.
In fact, the proposed strategy presents a structure consisting of four dc boost converters, which are actively controlled in order to produce two output dc-biased sinusoidal voltages across the load.
In the UK, two species in particular, the house mouse and the brown rat, are actively controlled to limit damage in growing crops, loss and contamination of stored crops and structural damage to facilities, as well as to comply with the law.
