Under the long time operation, some uncontrollable factors will affect the Maglev train-at-ground structure vertical coupling vibration, including the supported stiffness change of subgrade, uneven settlement and the supported void.
The result will also reveal uncontrollable factors of real operation which not show in program simulations but affect the performance of the turbines e.g. solid particle, unsteady wind speed and climate.
Because the success of emplacement and operation depends inevitably on uncontrollable aspects of the target environment, unattractive failure probabilities for individual vehicles must be tolerated that are higher than the typical '3-sigma' (99.5%) values typical for spacecraft.
In general, the filament size of the ReRAM can have random fluctuation owing to the randomly distributed oxygen vacancy (Vo) of binary metal oxide switching layers and the uncontrollable current flowing during the set operation.
Under the circumstance of uncontrollable climate change, effective measures for reservoir operation should be put forward to maintain the ecological integrity and ensure water release and storage capacity of aquatic ecosystems.
If a MEN is improperly designed, its operation may be unstable or even uncontrollable regardless of the advances of control techniques.
Imperfect and incomplete understanding of reaction kinetics compounded with uncontrollable variations not only prevent achieving an optimal operation of batch and semi-batch reactors, but also give rise to potential risks of violating product end-use properties, ecological or safety constraints.
There is growing, and often uncontrollable, anger among the people over the military operations being conducted across Balochistan.
Furthermore, the proposed scheme is robust against the insufficient data from uncontrollable DGs, since it provides an improved and stable operation even when there is no communication with uncontrollable DGs and loads.
The cavity growth rate (CGR) or the moving rate of the gasification face is affected by controllable (operation pressure, gasification time, geometry of UCG panel) and uncontrollable (coal seam properties) factors.
