NURBS were introduced into CAD/CAM systems predominantly for the representation of conventional objects, such as conics and quadrics. Among these, the circle played a critical role in representing a myriad of parts used in the every-day practice. Being the most universally used object, the circle has enjoyed the most popularity in science and engineering.(More)
This paper presents a methodology to repair flawed migrated models that are designed with knowledge-guided NURBS (KGN). Incompatible traditional CAD packages that are based on NURBS technology have been for many years carrying out the exchange of models and data through either neutral file formats (IGES or STEP) or proprietary formats. The exchange process(More)
Integrated high frequency devices require high permittivity dielectric materials with low loss as well as low sintering temperatures. Ceramics with higher permittivity (50<¿r<350) than conventional low temperature co-fired ceramics (5 < ¿r < 10) will drive further miniaturization of embedded capacitor components and resonators. For microwave and mmwave(More)
