N-sided hole filling plays an important role in vertex blending. To deal with the case that the corner is surrounded by rational surfaces (i.e. NURBS surfaces), an algorithm to fi...

This note conjectures that if two surface patches intersect with G1 continuity along an entire curve, the probability is one that the curve is rational. This idea has significance...

While process variations are becoming more significant with each new IC technology generation, they are often modeled via linear regression models so that the resulting performanc...
