In this contribution we present tool support addressing the multiple perspectives problem. For organizing and integrating multiple stakeholders, the development processes and notations they use, and the partial specifications they produce we use the ViewPoints framework. A formalization of the ViewPoints framework based on distributed graph transformation builds the foundation of our tool. Intr...

We describe an algorithm for solving an important geometric problem arising in computer-aided manufacturing. When machining a pocket in a solid piece of material such as steel using a rough tool in a milling machine, sharp convex corners of the pocket cannot be done properly, but have to be left for finer tools that are more expensive to use. We want to determine a tool path that maximizes the ...

Shoulder geometry of tool plays an important role in friction-stir welding because it controls thermal interactions and heat generation. This work is proposed and developed a coupled rigid-viscoplastic numerical modeling based on computational fluid dynamics and finite element calculations aiming to understand these interactions. Model solves mass conservation, momentum, and energy equations in...

Learning geometry must begin in a simple way from concrete to abstract, an intuitive perspective analysis, exploration long-term mastery. 3D Holograms are need assist teachers and students learning geometry. This research develops valid, practical effective Hologram. Research development used the ADDIE model. The Hologram is validated by material media experts field tested. Data analysis quanti...

A rapid geometry engine (RAGE) has been developed to allow for preliminary design analysis without labor-intensive CAD support. The geometry tool builds complex aircraft configurations using a component-based approach. Basic algorithms for creating the primary components are presented and discussed. Examples of many widely varying geometry models are shown. A select geometry model is analyzed w...
