But it can be difficult to wind down when you're wound up with caffeine or other stimulants.
However, due to the uncertainty of wind characteristics and the limitation of forecasting precision, it is difficult to accurately schedule wind power generation.
Slipstream is affected by the movement of the train relative to the ground, but this is difficult to include in wind-tunnel tests.
"We're trying to make this stress-free for the animals, which is difficult to do given the wind and heat.
Thus, it is difficult to argue that the wind profile at the site follow the log law or power law.
It is difficult to tell if he is winded from the pursuit or engaged in some kind of victory lap.
However, due to the isolation, the energy stored in the leakage inductor of the primary winding is difficult to be transferred to the output.
Hence it is difficult to determine if these genes activate wound healing by fibrinogenesis or if, on the contrary, they destroy fibrin clots by fibrinolysis.
In the absence of any performance advantage, the use of the edge technique for the spaceflight Doppler wind sounder is difficult to justify.
Because the PDF of transient power sags of wind power is difficult to obtain, it is difficult to employ common methods to deal with the uncertainty of transient power sags such as the stochastic methods or fuzzy methods [22, 23].
