dκ is a small angle rotated by the rotating camera around the main optical axis, which causes each image point to make a circular motion around the image main point. Since the rotation angle dκ is small, the motion of the imaging point can be considered to move on the tangent of the...
The order in which the transformations are applied influences the final orientation of the moving reference frame, even if the rotations are performed around the same point [1]. There are several ways to select rotation angles. Some of them are listed below....
In addition, we evaluate 1 A reliable eigenfrequency in matrix method is the value which the solution converges to as the grid point N increases (see Sect. 3), and larger N only gives the result with higher precision and consumes more computing time. However, in the current calculations, ...
4.19C shows a top view of the vortex chamber in the vicinity of the nozzle. V.V. Babenko suggested that the nozzle be executed as a turning point. V.N. Turick realized a rotary nozzle scheme to study various methods of controlling coherent vortex flow structures in a vortex chamber. Sign...
Another Approach — The Flyback Chronograph with Tachymeter Scale Assuming that the lack of either space or a navigator make the use of the multi-sequence timing board impractical, there is another approach that we can use to determine the speed per mile, over sequential measured miles — a fl...
a magnetic field is tremendous and it may – with consideration to their reciprocal interactions – contribute to the whole spectrum of results observed herein. Also, because opposite poles rotate around a certain point, the charged molecules present in a medium will move in an unpredictable, ...
A Later Version of this article was published on 29 November 2017 The Original Version of this article was published on 18 June 1998Abstract Rotating relativistic stars have been studied extensively in recent years, both theoretically and observationally, because of the information they might yield ...
Eventually, the star reaches a point where it becomes unstable to axisymmetric perturbations and collapses to a black hole. The instability grows on a secular timescale, in the sense that it is limited by the time required for viscosity to redistribute the star’s angular momentum. This time...
If, in this case, the center of rotation of the workpiece is not accurately known, there may occur a portion around the axis of the workpiece which escapes being cut by the tool. To avoid this situation, the lathe operator makes a point of aligning the tip of the tool to the dead ...
a rotor electrode that is disposed to face the stator electrode and is used for modulating the frequency of the first radio frequency together with the stator electrode; a vacuum seal that performs vacuum sealing around a rotation shaft for rotating the rotor electrode; and a bearing that is in...
