Computer simulation is widely recognized nowadays as a major tool for scientific discovery as well as engineering testing. Correspondingly, typical challenges in today's scientific computing can be profoundly different from most numerical analysis...

Visual computing is a wide area that includes computer graphics and image processing, where the ``eyeball-norm'' rules. I will briefly discuss two case studies involving numerical methods and analysis applied to this area. The first involves motion...

The possibility that a discrete process can be fruitfully approximated by a continuous one, with the latter involving a differential system, is fascinating. Important theoretical insights, as well as significant computational efficiency gains may lie...
