Contouring Curved Quadratic Elements
We show how to extract a contour line (or isosurface) from quadratic elements—specifically from quadratic triangles and tetrahedra. We also devise how to transform the resultin...

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...

A computable type theory for control systems
— In this paper, we develop a theory of computable types suitable for the study of control systems. The theory uses type-two effectivity as the underlying computational model, bu...

Innovations in computational type theory using Nuprl
For twenty years the Nuprl ("new pearl") system has been used to develop software systems and formal theories of computational mathematics. It has also been used to expl...

A Computational Approach to Binding Theory
This paper is a first step towards a computational account of Binding Theory (BT). Two algorithms that compute, respectively, Principle A and B have been provided. Particular atte...
