In this paper, the basic ideal of the Event Space Theory and Analyzing Events are expatiated on. Then it is suggested that how to set up event base library in developing application software. Based above the designing principle of facing methodology. Finally, in order to explain how to apply the Event Space Theory in developing economic evaluation software, the software of “sewage treatment CAD...

Today, they are students in colleges and universities. Tomorrow, they will be engineers in various industrial sectors. One of the primary goals of education is to prepare people for successful careers in the real world. As in every course, students want to obtain the maximum value of a CAD related course for their future careers. They want to obtain knowledge and skills that are most practical ...

Constructing a full CAD model of a part requires feature descriptions from all sides; in this case we consider surface patches as the geometric primitives. Most previous research in surface patch extraction has concentrated on extracting patches from a single view. This leads to several problems with aligning and combining partial patch fragments in order to produce complete part models. We hav...

The mass customization can make customized products with the mass products efficiency, which will become mainstream manufacturing mode in the 21 century. The design for mass customization is the most important factor in the mass customization, on the base of extracting the excellences of the modulization design and the variant design, the article brings forward an idea of module-based variant d...

This paper proposes several H∞ performance preserving controller reduction methods. One of the advantages of the proposed methods is that the weighting functions for controller reduction is easy to compute and is readily available from standard H∞ control design software. Numerical simulations show that the proposed methods are at least as effective as the best method available in the literature.

Since they help to specify the shape of real objects, geometric constraint systems encountered in CAD domain are often invariant by isometries. But other transformation groups can be considered to improve the solving process. More precisely, using different transformation groups leads to a new approach of decomposition which generalize in some sense the classical approaches. This paper presents...

cad and office integration ole for design and modeling a new technology for ca software What to say and what to do when mostly your friends love reading? Are you the one that don't have such hobby? So, it's important for you to start having that hobby. You know, reading is not the force. We're sure that reading will lead you to join in better concept of life. Reading will be a positive activity...
