This paper presents a framework for a learning based approach to dynamically evolve the conceptual structure of a database in order to facilitate virtual representation of data in a CAD environment. A generic object model is presented which spans applications from a wide range of engineering design domains. The object model is complemented with a schema model. The object model and the schema mo...

Integrating analytic tools within a production Computer Aided Design (CAD) environment provides designers the opportunity to evaluate the impact of design decisions much earlier in the design process than previously possible. Softdesk Energy is a design tool that integrates building energy analysis capabilities into a highly automated production drafting environment (AutoCAD and Softdesk AutoAr...

This paper presents two concurrent engineering tools for serving in process planning. The ®rst one, as``design for manufacturing'' utility, evaluates critical interactions between several types of machining features (i.e., holes, pockets, etc.) on prismatic parts, and modi®es original design (if possible) and re¯ects the modi®cations to all down-and upstream stations in CAD/CAM integration. The...

This experience report describes the development of the CASE environment CADDY Computer-Aided Design of non-traditional Databases 1 which oflers an integrated set of tools for specifying, analyzing, and prototyping a database application on a conceptual level. This environment was designed and implemented during the last four years at Braunschweig Technical University (Germany). The process of ...

A solution to get the problem off, have you found it? Really? What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the fundamentals of computer aided geometric design is one book that we really recommend you to r...

We give an overview of resultant theory and some of its applications in computer aided geometric design. First, we mention different formulations of resultants, including the projective resultant, the toric resultant, and the residual resultants. In the second part we illustrate these tools, and others projection operators, on typical problems as surface implicitization, inversion, intersection...

Graduate students can usually be classi ed in two categories: research engineers and practicing engineers. The microelectronic systems education of these two groups of students have di erent objectives. This paper describes a one semester course developed to meet the objectives for both groups of students. The course lectures cover custom and semicustom CMOS VLSI circuit design, and the laborat...

The following paper illustrates my ongoing research on the design of adaptive interaction (dialogs) in the context of database applications. I propose a separation between content (focus) and presentation and the use of guidelines rather than explicit speciications in order to achieve adaptive dialog descriptions. The resulting design process is far more complex than that for static interaction...
