If permissions is granted for further tests, it will not be until they are completed that Cuadrilla can be sure that the well will produce oil at a commercially viable rate.
For example, in Figure 2, the only viable rate control action for the queue size vector [4,0] is to activate transmitter 1 individually.
The optimal prediction performance corresponds to the point closest to the top left corner of the ROC plot (i.e. 100% true viable rate, 0% false viable rate).
The false viable rate obtained with SpoMBEL1693 (23.5%) was lower than that (46.4%) obtained with iMM904.
The ROC curve plots the true viable rate against the false viable rate thus allowing comparison of different models and methods without requiring arbitrarily choosing this parameter a priori [ 40].
If we allow evolution of the dispersal distance, we expect that for each viable rate of climate change, an optimal, evolved, dispersal distance should arise over time.
Estimated willingness to pay among vulnerable groups who most need insurance is, on average, lower than commercially viable rates.
Fracking is also likely to take at least five years to produce commercial quantities of natural gas, and although a government-commissioned geological survey found that decades-worth of the fuel are likely to lie below the surface, it is not known how much can be extracted at economically viable rates.
AD-SOFC systems could likely convert WWT plants into net generators of electricity rather than net consumers of electricity while generating economically viable rates of return on investment if the costs of SOFC systems are within a factor of two of the DOE/SECA cost targets.
Each insurance plan is supposed to have at least one FQHC in its network of providers and it is supposed to offer viable rates to at least one FQHC per county, but the details of what this means are not so clear.
Like most lizards, Komodo dragons are largely solitary from birth and generally remain asocial [6], with no evidence for behaviors that would enable viable rates of direct bacterial transmission between individuals' mouths [2].
