Section 3 synthesizes a class of planar 1R1T, 1R2T PMs with large rotational angles and two kinds of spatial PMs with high rotational ability and bifurcated motion by means of the Lie group theory. Using the proposed moving platform, Section 4 constructs a hybrid mechanism, of which mobility...
Rotational Symmetry of a Rhombus A rhombus has four equal sides but of varying angles. A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees. Also Check: Line Symmetry or Reflection Symmetry ...
As defects frequently govern the properties of crystalline solids, the precise microscopic knowledge of defect atomic structure is of fundamental importance. We report a new class of point defects in single-layer transition metal dichalcogenides that can
The 3D electro-mechanical mapping system NOGA XP (Biosense Webster, Inc., Irvine, CA, USA) allows simultaneous measurement of local electrical activity and mechanical motion of myocardial tissue. The data are generated by electro-magnetic tracking of a miniaturized sensor located at the tip of the...
A PU-equivalent PM can perform three degrees of freedom (3-DOF) motion that is identical to the end motion of a PU serial chain. The two axes of rotation always intersect and remain perpendicular. In other words, the rotation center of a PU-equivalent PM is restricted to a line; thus,...
In a 5-axis machine tool, which includes rotational axes, the orientation of the tool changes in various directions during machining. A workpiece may be machined by the tool side rather than the tool end, so the relation between the machined surface and the motion of the tool cannot be suff...

Versions Notes Abstract In this paper, the Penrose process is used to extract rotational energy from regular black holes. Initially, we consider the rotating Simpson–Visser regular spacetime, which describes the class of geometries of Kerr black hole mimickers. The Penrose process is then studied...
Review Reports Versions Notes Abstract In many real-world settings, image observations of freely rotating 3D rigid bodies may be available when low-dimensional measurements are not. However, the high-dimensionality of image data precludes the use of classical estimation techniques to learn the dynamics...
Versions Notes Abstract We demonstrate the emergence of an effective “time” axis in the ground state of a gauged rotational symmetry theory in four-dimensional Euclidean space. In so doing, we remove the necessity of Wick rotation to Lorentz spacetime, an arbitrary and sometimes ill-defined proc...
