s Proof of the Density of Rotations of a Circle through an Irrational Angle, ArtículoOne of the theorems of Nicole Oresme′s (ca. 1320-1382) says that, for two points moving uniformly but incommensurably along a circle, "no sector of a circle is so small that two such mobiles could...
whirling,gyration- the act of rotating in a circle or spiral pivot- the act of turning on (or as if on) a pivot; "the golfer went to the driving range to practice his pivot" pronation- rotation of the hands and forearms so that the palms face downward ...
Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 90° clockwise from point A. If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A′ li...
FreeCAD says something about ignoring a degenerate arc of circle, may or may not be related.Here is the full text from the terminal output:$ ./FreeCAD_0.21.0-Linux-x86_64.AppImage FreeCAD 0.21.0, Libs: 0.21.0R33675 (Git) © Juergen Riegel, Werner Mayer, Yorik van Havre and others...
A parallelogram, for example, has rotational symmetry of order two, and a square has rotational symmetry of order four. How do you know if a shape has rotational symmetry? To determine if a shape has rotational symmetry, spin the shape in a circle. If the original shape can be seen ...
Fix an irrational numberα, and consider a random walk on the circle in which at each step one moves tox+αorx−αwith probabilities 1/2, 1/2 provided the current position isx. If an observable is given we can study a process called an additive functional of this random walk. One ...
Humans can adapt their motor commands in response to alterations in the movement environment. This is achieved by tuning different motor primitives, generating adaptations that can be generalized also to relevant untrained scenarios. A theory of motor pr

We study the ergodic properties of compositions of interval exchange transformations (IETs) and rotations. We show that for any IET T, there is a full measure set of alpha is an element of [0, 1) so that T circle R-alpha is uniquely ergodic, where R-alpha is rotation by alpha.关键...
radius of the rollers is equal to or greater than R-X units and less than R units. Each roller crushes the coating at spaced locations to trap fluid between the rollers and the pocket. The rotor has an average diameter that interferes with the tangent circle of the stator-roller assembly....
