"functional modes" is correct and usable in written English.
You can use it to refer to a variety of related functions or modes of operation. For example, "The program provides several functional modes to manage the workflow."
Accordingly, functional architectures contain two functionally distinct ingredients: a repertoire of functional modes, conceptualized as phase flows, and additional operational influences acting at a continuum of time scales relative to the ones pertaining to the functional modes.
Which architecture is best utilized will thus be context dependent: unpredictable contexts demand for high flexibility do not even allow for complex functional modes, while the utilization of architectures whose functionality heavily depends on operational signals would be wasteful for the performance of repetitive and standardized actions.
ITSIE provides two distinct functional modes that are very useful from an educational and industrial point of view.
It is composed by a set of functional modes and a set of transitions to which statistical information regarding the system dynamics has been added.
This is done by testing the complementarities of three functional modes of knowledge (contextual, technological, and reconciliatory) in actuating the policy science of sustainability.
This Interactive Tool for System Identification Education ITSIEE) provides two distinct functional modes that are very useful from an educational point of view.
As more robotic technology has been developed and implemented for rehabilitation training, the conventional rehabilitation methodology is expected to change and to have various functional modes other than Continuous Passive Movement (CPM).
The directions of fluctuations in the most cooperative functional modes differ mainly around the dynamically key regions, i.e., the hinge axes, which appear to be more flexible in substrate complexes.
