Without unambiguous cues to depth, the direction of this rotating walker remains ambiguous; the changing 2-D pattern can be interpreted as a walker rotating in either clockwise (CW) or counter-clockwise (CCW) directions, with the respective interpretations having opposite starting orientations relative to the observer (Figure 1B).
The rotating disk allows the fiber to collect along the direction of rotation, because the rotating disc exerts a tangential force on the polymer jet to stretch and align the resulting fibers.
The geometry of this arrangement, as well as the rotating direction of individual rotating beam in an array, can be readily controlled by the configuration and topological charges of the vortex array.
Its primary purpose is to take advantage of the Magic Angle effect in MRI of human extremities, particularly the knee joint, by being capable of rotating the direction of the main magnetic field B0 about two orthogonal axes around a stationary subject and achieve all possible angulations.
For interactions with the Z instability, the shoulder abduction angle was small, which had the effect of rotating the direction of maximal stiffness vertically, toward the Z axis (Figure 8; third row).
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.
The plate has a principal direction of anisotropy rotated at an arbitrary angle relative to the coordinate axes.
It is shown that the time history of the magnitude of the unsteady loading is almost completely unaltered by angle of attack for the step gust, but it's direction of action rotates forward by an angle equal to the angle of attack, extending an earlier result by Howe for a flat plate in a turbulent flow to airfoils of arbitrary thickness.
With the increase of the rotating Reynolds number, the magnitude of rotating EMHD velocity decreases in axial direction and increases in lateral direction.
The angular momentum of rotating objects is a vector that has a value and a direction.
