We have developed a new method for transforming images with per-pixel displacements into textures that have correct parallax when texture-mapped, in the usual way, onto polygons. Our new method results from factoring the 3-D image-warping equations of McMillan and Bishop into a prewarp followed by standard texture mapping. The pre-warp handles only the parallax effects resulting from the direct...

To solve the problems of serious deformation and support difficulty deep narrow gob-side coal pillars, an optimized hydraulic roof cutting structural model for structure pillars in kilometer–deep shafts was established based on 6302 working face Xinhe mine. The influence factors such as angle height stress evolution analyzed, principle pressure relief revealed, industrial application conducted....

The goal of this study is investigating reduction of residual stresses from welding carbon steel plates through vibrationstress reliefmethod vs. thermal method. In order to carry out the required experimental tests, carbon steel plates were welded together under specific conditions as samples. Some of the samples were vibration stress relieved, some were thermal stress relieved while the rest r...
