Three dimensional models of shaft were completed on CATIA Part Design module with the Chinese national standard(GB) process structures such as chamfers, threads
In this paper,the smooth connection between two B-spline surfaces is discussed.First,a brief proof of some simple sufficient conditions of G~0 and G~1 continuit
Study of image enhancement shows that the quality of image heavily relies on human visual system. In this paper, we apply this fact effectively to design a new image enhancement method for medical ima
A new product conceptual design approach is put forward based on Hopfield neural networks models. By research on the mechanisms of Hopfield neural networks, the
