Robert C. process is robust, because it bases its decisions on grou s of mutual1 is rela Pively fast, % consistent features, and it ecause it concentrates on key features that are automatically selected on the basis of a detailed analysis of CAD type of models of the objects. @

Обсуждается развитие методов автоматизации подготовки чертежей на основе так называемых модулей, содержащих одновременно параметрическое представление части чертежа и соответствующие геометрические элементы. Как этапы эволюции модульной технологии автоматизации проектирования рассматриваются варианты применения модулей для простого объединения элементов без параметрического представления с возм...

This paper presents a necessary and sufficient condition for global convexity of planar curves and some applications of this condition. In addition, various ideas about the concept of convexity in CAGD are discussed. © 1997 Elsevier Science B.V.

The research is financed by the Chinese national 863 plan projects. No. 2006AA05Z409 Abstract Wind power generation potential of Guangzhou has been analyzed based on the wind speed data collected in the recent 30 years. In order to make the results more accurate, the Weibull distribution function is introduced and the two parameters can be identified by CAD method together with local weather da...

Here what I would like to accomplish is to set something of the stage from which the growing recognition of what I shall now term technoscience’s visualism—a term which can accommodate both sciences and engineering, and both imaging and design practices—takes its recognition. I shall very briefly look at the ‘godfathers and peers’ who help set this stage, and then proceed to an examination of a...
