In this paper we investigate the impact of different finite difference method (FDM) on estimation of the curvatures and other geometry properties of an implicit surface extracted from volumetric data. The FDM estimation case studies of the geometrical features are conducted on the surface in different resolutions which are refined surface, medium surface and coarse surface. A ground truth is established...
Intra-industry trade has become a main trade form in recent years. This paper focused on the empirical work on the determinants of intra-industry trade in Chinese manufacturing. We studied the determinants of intra-industry trade in Chinese manufacturing by considering the country characteristics and industry characteristics synchronously. Based on the regression analysis, we found that the level...
In this paper, a new family of two-dimensional (2D) wavelength-time codes, which uses one-dimensional (1D) optical orthogonal codes (OOCs) with the maximum cross-correlation value of two as the time-spreading codes is proposed and analyzed. By relaxing the cross-correlation functions to at most two, the new 2D codes can provide larger code cardinality to accommodate more subscribers. They also have...
Isosurface extraction is always an interesting topic in the field of computer graphics and scientific visualization. This study surveys isosurface construction methods, particularly in implicit surface polygonization using tracking partition. An investigation is conducted on the implementation of it. With reference of original Jules Bloomenthalpsilas implementation, an extension of the implicit surface...
