The paper deals with the electromagnetic forces in induction machines when the rotor is performing eccentric motion with respect to the stator. The studied eccentric motions of the rigid cage rotor are cylindrical circular whirling motion, symmetric conical whirling motion and the combination of these two basic modes of eccentric motions. The multi-slice, time stepping finite element analysis i...

We consider the formation of double white dwarfs (DWDs) through dynamical interactions in globular clusters. Such interactions can give rise to eccentric DWDs, in contrast to the exclusively circular population expected to form in the Galactic disk. We show that for a 5 yr Laser Interferometer Space Antenna (LISA) mission and distances as far as the Large Magellanic Cloud, multiple harmonics fr...

The circular grating is used as the measurement standard component in the robot joint-angle test system, however the measurement error is inevitable due to the installation eccentricity. In order to correct the measurement error, both the compensation model and eccentric detection test are needed to be investigated. Firstly, the compensation model about angular error is deduced according to the...

We have performed a detailed analysis of orbital motion in the vicinity of a nearly extremal Kerr black hole. For very rapidly rotating black holes—spin parameter a J=M > 0:9524M—we have found a class of very strong-field eccentric orbits whose orbital angular momentum Lz increases with the orbit’s inclination with respect to the equatorial plane, while keeping latus rectum and eccentricity fix...

The anisotropic emission of gravitational waves during the merger two supermassive black holes can result in a recoil kick merged remnant. We show here that eccentric nuclear disks - stellar eccentric, apse-aligned orbits directly form as result. An initially circular disk stars will align orthogonal to hole direction with distinctive 'tick-mark' eccentricity distribution and spiral pattern mea...
