In order to avoid artifacts, the rotational velocity, the sample's distance to the center of rotation, and the rotational acceleration (during velocity transitions) have to be chosen appropriately.
Non-accidental head injury, or "Shaken Baby" syndrome, caused by rotation-acceleration strains on the brain in the still loosely connected infant skull causes bleeding and swelling that can lead to catastrophic intracranial damage and can severely impair normal brain development (and can even lead to death) [ 23].
Rotation and acceleration supervene on spacetime interval relations.
Considering its anti-Machian models, we are inclined to say that motions such as rotation and acceleration remain absolute, or nearly-totally-absolute, according to the theory.
On the other hand, Mach is quite correct that Newton's argument in the Scholium leaves open the logical possibility that the privileged, true sense of rotation (and acceleration more generally) is some species of relative motion; if not motion properly speaking, then relative to the fixed stars perhaps.
Special focus in this paper goes to merging of heterogeneous data (displacements, rotations, and accelerations) obtained from different measurement systems.
The nodal co-ordinates, incremental displacements and rotations, velocities, accelerations and the equations of motion of the system are defined in terms of a fixed global co-ordinate system, while the total strains in the beam element are measured in element co-ordinates which are constructed at the current configuration of the beam element.
Additionally, note that the robot slips prior to rotation if the acceleration a does not satisfy Eqs.
GPS data combined with analysis of acceleration, rotation rate, and airspeed revealed that the secret to the birds' success may be their collapsible wings.
In other words, the robot can traverse the stairs without any slipping or rotation if its acceleration is controlled in the stable area (D).
We cannot put a body or system into a state of rotation (or other acceleration) without thereby changing the spacetime interval relations between the various bits of matter at different moments of time.
