Abstract We prove, using a non-standard complexity assumption, that any language in NP has a 1-round (that is, the verifier sends a message to the prover, and the prover sends a me...
We examine learning culture in a popular online game, World of Warcraft. We analyze the way players learn this complex game through chat conversation with peers. We describe three...
Abstract. A solid object in 3-dimensional space may be described by a collection of all its topologically distinct 2-dimensional appearances, its aspect graph. In this paper, we st...
In computer graphics and engineering many classes of complex objects can be designed with L-systems. We present a concept for enhancing timed and parametric L-systems with physics...
In this paper, we introduce localized homology, a theory for finding local geometric descriptions for topological attributes. Given a space and a cover of subspaces, we construct...
