In this paper , a rigidity theorem of hypersurface in real space form will begiven.In addition, we obtain rigidity theorems of submanifold in sphere which improvethe result of Hou and Xu.
The formula of the curve tangent slope at some peculiar point in the orthograph on the stereoscopic surface intersecting line and the method of making tangent are given as well.
This article not only discusses the ruled surface features of uniparted hyperboloid and its application in archtecture engineering but also discusses the teaching of the ruled surface.
Dual light path Laser Doppler Vibrameter System that can meet the out-of-plane vibration measurement for the slope plane and any curved surfaces is first proposed.
Based on human factor engineering, semi-generative therblig-based Computer Aided Process Planning (CAPP) technology was present to improve productivity and standard process operation for Shipyard.
The invention relates to a cambering printing machine, in particular to a high-speed cambering printing machine which can automatically proof the version.
It is over a hundred times faster than previous techniques, has less limitations as it works on curved surfaces, and, it only takes 40% longer to render it compared to the standard perfect material models.
The passengers are expected to spend about four minutes in this suborbital space, where they can experience weightlessness and observe the curvature of Earth.
In the Euclidean approach, the history of the universe in imaginary time is a four-dimensional, curved surface like the surface of the Earth, but with two more dimensions.
In the world of digital 3D modeling, it often occurs that we are looking for surfaces that are not perfectly smooth, but have some sort of surface detail.
