Cultural relic is the carrier of information, such as production, life, science and technology, art and so on. However, due to natural and man-made reasons, artifacts are often destroyed. Excavation site is the most common variety of cultural relics, the need for cultural relics repair. Because the artifacts are generally made on the rotating disk, so the object of this study is the rotating de...

The problem of constructing global models describing isolated axially symmetric rotating bodies in equilibrium is analyzed. It is claimed that, whenever the global spacetime is constructed by giving boundary data on the limiting surface of the body and integrating Einstein’s equations both inside and ouside the body, the problem becomes overdetermined. Similarly, when the spacetime describing t...

Rotating stellar models of 1.2 M down to 0.6 M have been computed to investigate the effects of rotation on the lithium depletion of low-mass, pre-main sequence stars. The models were generated under three different rotation laws (rigid body rotation, local conservation of angular momentum over the whole star, and local conservation of angular momentum in radiative zones and rigid body rotation...

The gravitational couplings of intrinsic spin are briefly reviewed. A consequence of the Dirac equation in the exterior gravitational field of a rotating mass is considered in detail, namely, the difference in the energy of a spin12 particle polarized vertically up and down near the surface of a rotating body is h̄Ω sin θ. Here θ is the latitude and Ω = 2GJ/(cR), where J and R are, respectively,...

The temperature distribution due to a rotating or dithering Gaussian laser beam on a finite body is obtained numerically. The authors apply various techniques to solve the nonhomogeneous heat equation in different spatial dimensions. The authors’ approach includes the Crank-Nicolson method, the Fast Fourier Transform (FFT) method and the commercial software COMSOL. It is found that the maximum ...

In this paper, we present a method for recovery of shape and surface re ectance of specular object from color images taken with the light source rotating. The image sequence is taken with a xed camera while the light source is relatively rotating around the axis parallel to the optical axis of the camera. We derive the relationship between the body re ectance at every object surface point and t...
