The variation process depends on continual variation of a constant factor, such as a theme or a group of harmonies.
A major reason for selecting alternating current for power networks is that its continual variation with time allows the use of transformers.
A new design of gear transmission unit with continual variation of gear transmission ratio, for application in wind turbines (WT), has been developed.
Other traditional detection methods are also becoming more and more of limitation due to continual variation of microorganisms, emergence of new pathogens and flaw of method itself such as low accuracy, poor specificity and so on.
The reaction of the blood is maintained as constant as possible by a continual variation of the respective values of... several factors, so that an estimation of the value of any one, or any particular clinical symptom, such as whether alkaline reserve, free CO2 rapid breathing, may be wholly misleading.
Folk songs were extended by a continual series of variations which played behind the melody as it was repeated.
So for selection to gradually modify a population over a long period of time, in the manner suggested by Darwin, a continual supply of variation is needed.
Most forms of selection reduce the amount of genetic variation within populations, which may be counteracted by the continual emergence of new variation via undirected mutation and recombination.
Consistent, directional change requires the continual addition of new variation (by mutation at the population level, by speciation at the species level).
We offer several suggestions for a new stress test that include: continual updates and testing; variation across markets; and, like the recent FRB stress test, the scenario should be based on real (rather than nominal) price patterns.
