Induction Motor Hybrid Coordinate Transformation Model and Its Application
Journal of Harbin University of Science and Technology, 2018 For the strong coupling problem between the rotor current and the air gap flux in the expression of the electromagnetic torque expression of the induction motor，the hybrid coordinate transformation is adopted by the αβ0 transformation and the MT0 ...

Misconceptions About General Relativity in Theoretical Black Hole Astrophysics [PDF]
, 2010 The fundamental role played by black holes in our study of microquasars, gamma ray bursts, and the outflows from active galactic nuclei requires an appreciation for, and at times some in-depth analysis of, curved spacetime.

Are Simple Real Pole Solutions Physical? [PDF]
, 2000 We consider exact solutions generated by the inverse scattering technique, also known as the soliton transformation. In particular, we study the class of simple real pole solutions. For quite some time, those solutions have been considered interesting as

Hidden Symmetries of M Theory [PDF]
, 1998 A worldvolume action for membrane is considered to study the target space local symmetries. We introduce a set of generators of canonical transformations to exhibit the target space symmetries such as the general coordinate transformation and the gauge ...

Recovery of a Smooth Metric via Wave Field and Coordinate Transformation Reconstruction [PDF]
SIAM Journal on Applied Mathematics, 2017 In this paper, we study the inverse boundary value problem for the wave equation with a view towards an explicit reconstruction procedure. We consider both the anisotropic problem where the unknown is a general Riemannian metric smoothly varying in a ...

Magnifying perfect lens and superlens design by coordinate transformation [PDF]
, 2007 The coordinate transformation technique is applied to the design of perfect lenses and superlenses. In particular, anisotropic metamaterials that magnify two-dimensional planar images beyond the diffraction limit are designed by the use of oblate ...

A Novel High-Squint Spotlight SAR Raw Data Simulation Scheme in 2-D Frequency Domain
Remote Sensing, 2022 Raw data simulation is the front-end work of synthetic aperture radar (SAR), which is of great significance. For high-squint spotlight SAR, the frequency domain simulation algorithm is invalid because of the range-azimuth coupling effect.

Note on ingoing coordinates for binary black holes [PDF]
, 2003 In a previous paper, a binary black hole four-metric was presented in a post-Newtonian corotating coordinate system valid only up to the holes' apparent horizons.
