Optimal Parsing Trees for Run-Length Coding of Biased Data
Abstract-- We study coding schemes which encode unconstrained sequences into run-length-limited (d, k)-constrained sequences. We present a general framework for the construction of...

Animating developable surfaces using nonconforming elements
We present a new discretization for the physics-based animation of developable surfaces. Constrained to not deform at all in-plane but free to bend out-of-plane, these are an exce...
