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
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....
We consider the quasinormal modes, quasibound states and superradiant instability of a rotating hairy black hole, which possesses a Horndeski hair as devia
Every single photon that approaches the observer determines a point on the (α, β)-plane of the image, which can be visible with the help of telescope. The size and shape of the shadow depends on the parameters of black hole as well as on the inclination angle θ0. The pictorial ...
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...
[1] as the massless rotating solution, perturbed by its mass. The key point of this second-step procedure is to find the viable ODE, by separating the angle-dependent rotating metric, parameterized by the spina, and the additional (r-dependent, without cosmological constant) corrections due to...
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, ...
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...
(7) From the event horizon formula, it can be observed that when (a2 + m2) ≤ 2, the rotating black-bounce space- time represents a black hole. However, when the condition (a2 + m2) > 2 is satisfied, resolving it yields J > M2 β2 − m2 M2 , (8) where = Mβ, at this...
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 ...
