Sharp Features on Multiresolution Subdivision Surfaces
In this paper we describe a method for creating sharp features and trim regions on multiresolution subdivision surfaces along a set of user-defined curves. Operations such as engr...

Sharp or smooth?: comparing the effects of quantization vs. frame rate for streamed video
We introduce a new methodology to evaluate the perceived quality of video with variable physical quality. The methodology is then used to assess an existing guideline that high fr...

Complexity of admissible rules
We investigate the computational complexity of deciding whether a given inference rule is admissible for some modal and superintuitionistic logics. We state a broad condition unde...
