Work schedules may differ by the time of day (i.e. day, evening, night), fixed versus rotating schedules, direction of rotation, number of hours worked per week, number of consecutive days worked, number of rest days, and so on.
If the transition graph allows more than one rotation number, then this probability distribution exhibits rotational chaos.
Control conditions were imposed on: Reynolds (Re), rotation number (Ro), buoyancy number (Bu) numbers for both rotating channels, radial outward flows were controlled in the ranges of: 5000 ⩽ Re ⩽ 15000, 0 ⩽ Ro ⩽ 0.3 and 0 ⩽ Bu ⩽ 0.23 respectively.
Let us introduce the rotation number for (2.1).
By definition (2.16) for the rotation number, we obtain (4.41).
Such a number is called the rotation number of (2.1).
Simple expressions are obtained to correlate integral time scale with rotation number.
A key feature of an orbit of a degree-one circle map is its "rotation number".
Thus, the rotation number for the analytic case may not give accurate information.
We next introduce the definition of rotation number of a continuous path in (mathbf{R}^{2}).
Let f be a circle homeomorphism with irrational rotation number ρ.
